- Description: The study is a psychobiographical case study based on the life of a Victorian baby farmer Amelia Dyer (1837-1896). She was executed for the murder of babies who were placed in her care over a period of 30 years. Psychobiography is a qualitative method of enquiry which explores the life of a unique individual subject through the lens of a psychological theory for the purpose of creating a coherent psychological case study. The psychoanalytic theoretical lens of Karen Horney was used to trace the evolution of Amelia Dyer’s sense of self within the Victorian culture of respectability. Baby farming referred to an unregulated business of adoption and fostering of infants, mostly illegitimate infants for a fee. Insufficient social structures and support for unwed mothers and children encouraged the business practice as women had very little choice for childcare. Baby farming was open to abuse and exploitation and hundreds of babies lost their lives due to insufficient care or infanticide. Amelia Dyer showed special talents and creativity from a young age, was ambitious and wanted to be self-reliant in a culture that did not provide women with opportunities to live out their ambitions. Baby farming became a business venture for her in the early stages of her life which later evolved into sadistic abuse and murder of the infants. Her evolution from a creative and hardworking young girl to a sadistic murderer of children is what qualifies her as a suitable subject for the exploration of Karen Horney’s dynamic theory of neuroses and the development of the neurotic self within culture. Extensive biographical data was collected and processed into salient themes. The study integrates the theory of Karen Horney, the life experiences of Amelia Dyer and Victorian respectability and demonstrates the value of using psychobiography as the method of inquiry into the exploration of the unique individual. The findings of the study demonstrated that Amelia Dyer and her social context were inextricably bound by a vicious cycle of psychic and emotional vi conflicts related to fear, control and self-hatred by the internalization of gender stereotypes and norms. The contribution of the study as a whole rests with its demonstration of the value of a holistic and reflexive exploration of the unique individual woman. It demonstrates the value of Horney’s in-depth theoretical understanding of the ambivalent core of selfhood that lies behind observable acts of behavior. The study as a whole contributes towards building upon holistic and integrative therapeutic frameworks in the understanding of diversity amongst women and mothers in culture.

- Description: Medicinal plants have long been used in folkloric medicine in various parts of the world. Presence of phenolic compounds has been attributed to their medicinal properties. Despite various medicinal uses, scientific claims of anti-hypertensive activities are still deficient. Therefore, hydroethanolic (70% ethanol) extracts of the leaf and root parts of T. officinale (TOL and TOR respectively) were investigated for anti-hypertensive antioxidant, diuretic activities, and effects on lipid profile in L-Name-induced hypertensive Wistar rats. Phytochemical screening of TOL and TOR was assessed by known standardized method. Acute toxicity profile of the plant was also evaluated by Lorke’s method. Total phenolic and flavonoid contents were assessed using Folin Ciocalteau and Aluminium chloride colorimetric methods; while, 2, 2-diphenyl-1-picrylhydrazyl (DPPH), 2, 2’–azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS)and ferric antioxidant reducing power (FRAP) protocols were used for their radical scavenging and total antioxidant capacities respectively. Spontaneously hypertensive rats were used for acute antihypertensive study while for the 21 days antihypertensive study, hypertension was induced by administering L-Name (40 mg/kg) for 4 weeks and, CODA 8 Non-invasive tail cuff machine was used to measure blood pressure. With the aid of a semi-auto chemistry analyzer, lipid profile of Taraxacum officinale (TO) was determined using Biosinol reagents. TOL and TOR also significantly reduced systolic, diastolic and mean arterial blood pressures up until 4 hours with the leaf part most active in single dose study using SHR model. TOL and TOR also significantly lowered systolic, diastolic and mean arterial blood pressures with the leaf part most active in 21 days study using and L-Name-induced HTN models. However, these plant extracts did not have a diuretic effect, but seems to exert its antihypertensive effects by modulating NO production and possibly bioavailability, by acting via an endothelium-dependent pathway. This study validates the traditional use of the leaf part of the plant as an antihypertensive agent.

- Description: The current study is a psychobiography. The subject was chosen through purposive sampling based on the researcher’s personal interest and the remarkable impact this woman had within her society. Ellen Kuzwayo also meets the requirements of a psychobiography in that she is historically well known, inspirational, and her life has been completed. The study applies a qualitative research method in the form of a psychobiography, which aimed to describe Ellen Kuzwayo`s life accordingto Daniel Levinson`s Life Structure Theory of Adult Development. Levinson`s theory divides the lifespan into four developmental eras, each with its own biopsychosocial character. Each era in turn is divided into shorter periods of development. Levinson`s theory was chosenbecause it is specifically relevant to the development of women. The findings of the study indicate that Kuzwayo’s life was consistent with the pattern of development which Levinson (1996) identified. Kuzwayo was relatively successful in resolving the life tasks and transitional periods proposed by Levinson. This research study has given a positive demonstration of the value of development theory to investigate a particular human life. Furthermore, it emphasized the uniqueness of individuals in coping with the challenges of life. As a result it has opened up the possibility of perceiving people and their actions in a different way. Consequently, recommendations are offered in order to extend psychobiographical research on the life of Ellen Kuzwayo.

- Description: In response to the growing demand for a test of cognitive ability for South African adults, the Human Sciences Research Council (HSRC) adapted the Wechsler Adult Intelligence Scales, third edition (WAIS-III) for English-speaking South Africans. However, since the publication of the South African adaptation in 2001, there has been some concern whether some bias may not still be present in the measure. Consequently, this study aimed to qualitatively explore the item content of the South African adaptation of the WAIS-III in order to identify items that might still be potentially biased with specific reference to cultural and linguistic issues. The researcher employed purposive sampling, a non-probability technique, to select psychology professionals to act as expert reviewers. The sample consisted of 20 registered psychologists, psychology lecturers and psychology interns from the predominant culture and language groups of the Eastern and Western Cape. Qualitative and quantitative data were collected by means of a Bias Review Questionnaire which consisted of fixed-choice questions, as well as sections in which specific comments could be indicated. The questionnaire was distributed to 20 selected participants who were qualified to administer psychometric measures and were registered with the Health Professionals Council of South Africa (HPCSA). Qualitative data was analysed using Tesch’s model of thematic content analysis, and five main themes relating to potential bias were identified, namely: Culture, Language, Education, Socio-economic status, and Format. The qualitative data was re-submitted to the expert review group for approval and further comment. Quantitative data obtained from the Bias Review Questionnaire was analysed by obtaining frequency counts, which were converted to percentages, per subtest and aspect reviewed. The major findings of the study were as follows: 1. Cultural bias is evident in the South African adaptation of the WAIS-III. The differential meanings ascribed to concepts, terms, phrases and words by diverse cultures impact on test performance, as does familiarity with stimulus materials used in the measure. 2. Language bias was detected against groups with English as their second or third language owing to the unfamiliar, and sometimes archaic, terms and vocabulary used in the measure. The intended meanings of the translated items are unclear and confusing for test-takers. 3. South African test-takers have experienced vastly divergent educational opportunities which impact on intelligence test performance. The measure contains potential bias against individuals from disadvantaged educational backgrounds. 4. The content of the items is not relevant to test-takers from deprived socioeconomic backgrounds that have been unable to access good-quality education. 5. Format bias was found to exist with respect to the timed tests. Cultural groups who do not value speededness are disadvantaged by the structure and format of the measure. Based on the findings of this study, certain recommendations were made. These include: 1. Additional qualitative investigation of the WAIS-III , with a view to further adaptation in an effort to eradicate bias on cultural or linguistic grounds, and 2. Conducting further Differential Item Functioning (DIF) analyses and establishing construct equivalence across cultural and linguistic groups to promote this objective. Among the contributions believed to have been made by this study are the identification of potentially biased subtests and items on the grounds of culture and language, which will facilitate possible further revision and adaptation of the measure. Additionally, the variables that were considered important influencing factors of cognitive test performance have been documented and are accessible for future research that will supplement the present study.

- Description: With the changing landscape in South Africa to a full democracy, increased research has been undertaken in the psychometric field on local and national normative studies regarding various assessment measures. Given that the Raven’s Coloured Progressive Matrices (CPM)is purported to be culture-free and not heavily dependent on verbal and language skills;it has been extensively normed throughout the world for various population groups. While norms for normal populations of children have been developed in South Africa, these studies were based on race and gender predominantly and without taking into consideration the effects of socio-ecological factors on test performance. The research study aimed to understand the influence of socio-ecological factors on the expression of cognitive scores amongst a geographically diverse sample of South African learners. Through this study, research on the interplay between context and cognition was to be located within the Ecological Systems model of Bronfenbrenner. A secondary aim of the study was to develop an index that will guide test selection and interpretation of assessment results, taking into account the influence of socio-ecological factors and providing a conceptual framework for future test development. The study employed a quantitative methodology on a South African sample consisting of primary school children aged between the ages of 6 years to 11 years. The sample was drawn from schools in the Port Elizabeth areain South Africa that wereclassified into low, medium and high opportunity, based on context. The results indicated that the type of school had a significant impact on test performance, suggesting that contextual factors were influential in this process.The item analysisconductedfurther indicated that learners from a low opportunity school performed significantly lower than the other two schoolsin the sample. The index development provides a foundation for further research that would enhance the interpretation of test results. In the South African context, this is considered important, given our political history and our diversity wherea“one size fits all” approach is not possible.

- Description: With the changing landscape in South Africa to a full democracy, increased research has been undertaken in the psychometric field on local and national normative studies regarding various assessment measures. The Raven’s Coloured Progressive Matrices (CPM) is one of the measures that have already been extensively normed throughout the world for various population groups. In South Africa, local norms for normal populations of children have been developed by groups of researchers in the Grahamstown (Eastern Cape) as well as the Bloemfontein (Free State) areas. With a South African school educational system that focuses on Inclusive Education, there is a growing need for mainstream schools to identify learners who are at risk for learning disabilities in order to develop appropriate supportive intervention plans. The research aimed to establish psychometric normative screening data based on the Raven’s CPM, and to compare these with the established and published international and local Raven’s CPM norms. In addition, the researcher developed pilot classification scores for the early screening and detection of at risk learners in order to encourage the potential role and use of the Raven’s CPM in the identification of cognitive learning barriers. The sample consisted of 388 primary school learners identified as having cognitive barriers to learning. Archival data was used that was gathered from a Psychological clinic that provided screening services to schools in the Nelson Mandela Metropolitan area. The results of the study indicated that there was a proportional relationship between age and test performance. Gender differences were found where the males in this study outperformed the females. There was a significant difference in the Raven’s CPM test performance with respect to the grade levels of the learners. The study developed a special set of norms with cognitive classification scores that will aid in the early identification of learning disabilities.

- Description: The present study sought to explore the functional changes that occur in the vasculature of HIV positive participants of African origin in Mthatha district of South africa which might lead to increased risk in their cardiovascular system. Available literature shows that arterial stiffness plays an important role in cardiovascular events such as stroke, vasculitis and myocardial infarction. Measurement of (aortic pulse wave velocity; PWV) provides some of the strongest evidence concerning the prognostic significance of large artery stiffening. This study was aimed at investigating the relationship between anthropometry, age, E-Selectin level, cytokine levels, haemodynamic variables, blood counts and blood lipid profile with pulse wave velocity. Some traditional cardiovascular risk factors such as alcohol, and smoking were also taken into account. This was a cross-sectional study comprising of 169 participants (62 males and 107 females). 63 were HIV negative (group A), 54 HIV positive on treatment (group B), and 52 were HIV positive not on treatment (group C). Pulse wave velocity (PWV) was assessed using the Sphygmocor Vx. Statistically, ANOVA was used for variables with normal distribution and non parametric tests were used for variables with skewed distribution. Notable significant differences were seen in the means of the following variables across all the 3 groups. Conclusion: This study showed that HIV infected patients with or without antiretroviral therapy have increase arterial stiffness which is associated with an increased cardiovascular risk. The sphygmocor is an accurate, non invassive and useful tool in the evaluation of arterial stiffness and its use in clinical practice should be encouraged. PWV and the augmentation index (AIx) are the two major non- iv invasive methods of assessing arterial stiffness. Life style modification should be incorporated into the management of HIV patients so as the continuous monitoring of their haematological and lipid profile.

- Description: The primary aim of this study was to investigate the seasonal changes that occur in the anthropometric, physical and motor characteristics of elite junior soccer players over the course of a training year. The participants targeted were elite soccer players from the NMMU-FCK Soccer School of Excellence and a total of 18 players between the ages of 15 to 18 years were recruited to comprise the sample for the study. The participants in the sample were assessed on four separate occasions. Each testing period was separated by a three month interval with the first testing period taking place in June 2005, at the start of their pre-season period, and the last testing session taking place in March of the following year, at the end of their playing season. In order to determine which specific characteristics of soccer were to be tested, the relevant literature was reviewed to establish the requirements, attributes and indicators of success in elite soccer. Therefore the test battery used was compiled in an attempt to address each of the identified physical attributes that contributes to successful soccer play. The battery included the following tests: weight, height and percentage body fat to represent the anthropometric characteristics. The physical characteristics were assessed by testing flexibility, anaerobic speed endurance, aerobic endurance, and muscular strength tests (1 RM bench and leg press, grip strength, and isokinetic knee strength). The motor assessments comprised of tests for speed (10-m, 20-m, and 40-m), explosive leg power (vertical jump), agility, and soccer-specific tests (dribbling and shooting at goal). In addition maturity status during the study was assessed using grip strength and height scores. All of the participants within the study sample were assessed on each day of the testing period, in alphabetical order, and this order was maintained during each testing period. Each of the four testing sessions lasted three days. On entering the Nelson Mandela Metropolitan University-Biokinetics and Sport Science Centre (NMMU-BSSC) laboratory on day 1, the participants completed the test battery in the following order: anthropometric measurements (weight, height, skinfolds), flexibility test (sit and reach), leg power test (vertical jump), muscular strength tests (1RM bench press, 1RM leg press, grip strength), and an aerobic endurance test (Multi-Stage Shuttle Run). The tests conducted on day 2 of the test battery were conducted as field tests at the NMMU-FCK soccer playing fields and the participants completed the tests in the same alphabetical order as day 1. The testing battery was conducted in the following order: speed tests (10m, 20m, and 40m sprinting), agility test (Illinois agility run), soccer-specific tests (dribbling and accuracy tests), speed endurance test (Yo-Yo intermittent recovery test). Testing on day 3 consisted of Isokinetic dynamometry strength testing and was conducted at the NMMU-BSSC. Each participant completed the testing protocol according to the same alphabetical order as was used on days 1 and 2. In order to achieve the aim of the study, the following objectives were set: to determine the anthropometric, physical and motor characteristics of the participants at the pre-season, start of season, mid-season and end of season stages of the training year and to identify the peak scores achieved for each variable tested; to compare the variables tested at each of the four testing sessions to determine the progression of each variable tested and to identify at which testing session peak performance related fitness was achieved; to compare the results obtained with relevant data from other research literature; and to monitor the maturation status of the participants. Based on the results achieved it can be concluded that the participants achieved peak physical fitness at the mid-season period (testing session 3). It would appear that the attainment of these results was determined by the participants being exposed to both a pre-season and an in-season training period. It seems that both the completion of the specific types of training that occurred during these two periods, as well as the competitive matches played, elevated the participants physical fitness to the levels required for success at the elite level.

- Description: Physical inactivity and resultant chronic diseases of lifestyle (CDLs) are becoming a global epidemic as secular modernization and the sedentary lifestyles it brings with it become universal. The importance of physical activity (PA) in reducing morbidity and mortality from CDLs and related conditions has been well established. Since it is generally significant that the onset of many CDLs lies in childhood through to adolescence, preventative strategies should start as early in life as possible. Currently, university students are failing to engage in the levels of PA recommended for better health outcomes over the short and long term. To make matters worse, there is increasing evidence of a decrease in PA during the transitional phase from adolescence to adulthood. This study aimed to determine the physical activity (PA) levels, sedentary behaviour and health-related fitness (HRF) characteristics of female university students. In addition, the participants‘ perceived barriers to PA were investigated. The study was exploratory-descriptive and employed a quantitative research design. Five hundred and thirty-one full-time female students, between the ages of 18 and 46, studying at Nelson Mandela Metropolitan University‘s (NMMU) South, North, Second Avenue and Missionvale campuses participated in the study. The participants (n=531) completed an online survey which determined their PA levels, sedentary behaviours and perceived barriers to PA participation. A health-related fitness (HRF) assessment was also administered to 68 participants who completed the online survey. Their height, weight, and waist and hip circumferences were measured, as well as their cardiovascular fitness (CF). The majority (88 percent) of the participants reported low and minimal levels of PA, and 44 percent were either overweight or obese. The participants had a low-risk waist-to-hip ratio (WHR) (M=0.70). The majority of the population (94 percent) had poor cardiovascular fitness (CF). A high prevalence of sitting time was recorded among the participants: on average 855 minutes (14 hours) on a usual weekday and 720 minutes (12 hours) on a usual weekend day. Students reported the greatest length of sitting time at work/attending lectures/studying. Cross tabulations and Chi2 tests indicated no significant relationships among PA and HRF (BMI, WHR and CF) and sedentary behaviour and HRF. The ANOVA and t-test results for PA, sedentary behaviour and HRF related to various demographic variables, found small (0.19 < d < 0.50) and medium (0.49 < d < 0.80) significant differences by race (d=0.43; d=0.52), home language (d=0.41; d=0.44) and living arrangement (d=0.38; d=0.28). No significant relationship was found to exist between age, year of study and faculty of registration and sedentary behaviour or HRF. The participants listed: Not enough time; too expensive to exercise; and, no friends who can exercise with me as the most important barriers to participation in PA. Academic obligations (3.08 mean) was found to be the most important barrier to PA.

- Description: There is a global increase in research on the benefits of animals and the value of incorporating them into interventional practices. This is referred to as animal-assisted interventions. Due to the novelty of this type of intervention and the accompanying complexity of variables, a need exists to explore the various aspects within these interventions. Looking specifically at animal-assisted interventions within the mental health field, this study focuses on the psycho-therapeutic value of companion animals, such as dogs and cats. The primary aim of this study was to identify the mechanisms through which an animal-assisted intervention exerts its influence. A secondary aim was to indentify salient methodological aspects within the included studies. A systematic review of existing literature was undertaken to explore these factors. Each study was appraised against specific inclusion and exclusion criteria and themes were extracted. The data was synthesised, integrated and discussed in relation to previously conducted studies in relevant fields. Six themes emerged from the systematic review. These included enhanced comfort, the living nature of animals, physical contact, adjunctive nature, an affinity for animals, as well as methodological considerations. Based on these emergent themes conclusions were drawn as to the psycho-therapeutic influences of companion animals. This may serve as informative knowledge regarding animal-assisted interventions for practitioners seeking additional methods to reach treatment goals. Information is also provided for researchers interested in the field, particularly methodological considerations, before embarking on a study of animal-assisted intervention efficacy.

- Description: Research has shown that Attention Deficit Hyperactivity Disorder (ADHD) is one of the commonest neurodevelopmental disorders which has a negative impact on a child. However, to date limited research has been conducted on learners, and specifically those learners with ADHD, within a National Education stream. Furthermore, running concurrently with this are new developments in education in South Africa. An inclusive educational policy favours the incorporation of all children into a mainstream scholastic setting, regardless of their diverse needs. In addition to educational changes for children with ADHD, many parents are presently unable to afford the medication commonly used to treat the disorder, resulting in both parents and teachers having to manage these children with limited professional support. It is widely accepted that early assessment and intervention are necessary in order to maximise a child’s potential. For this reason, the primary aim of this study was to explore and describe the developmental profile of children with ADHD on the Griffiths Mental Development Scales-Extended Revised (GMDS-ER). Further aims were to compare the performance of the clinical sample to a normal South African sample. In order to achieve these aims, a quantitative, exploratory-descriptive research design was employed. The sample (N = 38) of ADHD were selected by means of a non-probability, purposive sampling procedure, from various pre-school and primary schools in the Nelson Mandela Metropole. The normal sample (N = 38) was drawn from an existing database created during the revision of the Scales. Information was collated using the Conners 39 Item Teacher Rating Scale, biographical data, as well as the results of an assessment from the GMDS-ER. In this study the general performance of the ADHD sample on the GMDS-ER was found to be above average. Furthermore the performance of these children on the six Subscales of the GMDS-ER ranged from average to superior, with the poorest performance being on the Eye and Hand Co-ordination Subscale, and the best performance being on the Performance Subscale. Significant differences between the ADHD and normal sample were found on the General Quotient (GQ) as well as three of the six Subscales, namely, the Hearing and Speech, Eye and Hand Co-ordination and Performance Subscales. Generally, the results of the study suggest that a specific developmental profile for children with ADHD exists. Additionally, the study highlighted the success with which the GMDS-ER can be utilised on a specific clinical population.

James Warren “Jim” Jones was selected through purposive sampling because of his instrumental role in organising the largest mass suicide in recorded USA history. Kernberg‟s (1979; 1985; 2004) object relations theory was used to illuminate his life and personality dynamics, a theory focused on describing the borderline personality organisation. The study employed a qualitative single case study design, and data was analysed according to the principals set out by Yin (1994) as well as Miles and Huberman (1994). Results indicated that Kernberg‟s (1979; 1985; 2004) theory was suitable in shedding light on the life of this infamous historical figure, which resulted in an increased understanding of the application of this psychological theory. Lastly, it contributed towards increasing the limited number of psychobiographical studies conducted in South Africa.

- Description: Type 2 diabetes mellitus (DM) is a frequent adverse effect of antiretroviral drugs for those who are on ARVS. People with type 2 DM can suffer multiple complications that hinder the quality of life. In South Africa research has shown significant increase in neuropathy, heart and kidney diseases among patients living with type 2 DM and HIV/AIDS compared to DM without HIV. Accessed knowledge lacked consistency on the predictors of DM in HIV/AIDS patients with regards to the type of ARVS with higher risks of DM. Research needed to be done to find the determinants of type 2 DM in HIV/AIDS context. The purpose of this study was to describe the determinants of type 2 DM among HIV/AIDS patients on ARVS in the OR Tambo District, SA in order to develop intervention strategies to mitigate the long-term effects of type 2 DM. A quantitative research methodology using a case control retrospective study was used. A sample of 177 (33%) cases with HIV/AIDS and type 2 DM was selected using a one stage stratified sampling with allocation proportional to size of each stratum of the four sub-districts of OR Tambo District. Two non-diabetic patients with HIV/AIDS were selected as controls per case unpaired and totalled up to 354 (67%) controls. A self-administration questionnaire adopted from the WHO (2011) STEPwise surveillance tool for chronic diseases was used for data collection. Stata (standard version 13.0, Stata Corp., Lakeway Drive USA) was used for data management and analysis. Findings of the study revealed determinants of type 2 DM grouped as the socio-demographic determinants; tertiary education and marital status, levels of physical activities; lack of vigorous activity and sport, types of diets; high fruits and vegetables and healthy eating out at restaurants, arterial blood pressure; lack of routine BP check and known HPT and types of ARVS used in HIV/AIDS therapy. Compared with patients who received FDC, the risk of type 2 DM was 43 times and 22 higher when a tri-therapy regimen contained Ritonavir and Lopinavir respectively . The majority of DM patients (n=177) were diagnosed type 2 DM after ARVS at n=108 (61%). In managing the diabetic patients a shift from a single disease to multiple-chronic disease focus is required to mitigate the complex drug interactions that exist in the control of NCDs such as HIV/AIDS, DM, HPT and other long-term diseases. The HIV/AIDS and type 2 DM awareness and care intervention strategy is recommended as healthy lifestyle, monitoring of side effects and drug interactions, enhanced FDC roll out and elimination of unsafe ARVS to improve the health outcomes of type 2 DM patients in an HIV/AIDS context in OR Tambo District.

- Description: Type 2 diabetes mellitus (DM) is a frequent adverse effect of antiretroviral drugs for those who are on ARVS. People with type 2 DM can suffer multiple complications that hinder the quality of life. In South Africa research has shown significant increase in neuropathy, heart and kidney diseases among patients living with type 2 DM and HIV/AIDS compared to DM without HIV. Accessed knowledge lacked consistency on the predictors of DM in HIV/AIDS patients with regards to the type of ARVS with higher risks of DM. Research needed to be done to find the determinants of type 2 DM in HIV/AIDS context. The purpose of this study was to describe the determinants of type 2 DM among HIV/AIDS patients on ARVS in the OR Tambo District, SA in order to develop intervention strategies to mitigate the long-term effects of type 2 DM. A quantitative research methodology using a case control retrospective study was used. A sample of 177 (33%) cases with HIV/AIDS and type 2 DM was selected using a one stage stratified sampling with allocation proportional to size of each stratum of the four sub-districts of OR Tambo District. Two non-diabetic patients with HIV/AIDS were selected as controls per case unpaired and totalled up to 354 (67%) controls. A self-administration questionnaire adopted from the WHO (2011) STEPwise surveillance tool for chronic diseases was used for data collection. Stata (standard version 13.0, Stata Corp., Lakeway Drive USA) was used for data management and analysis. Findings of the study revealed determinants of type 2 DM grouped as the socio-demographic determinants; tertiary education and marital status, levels of physical activities; lack of vigorous activity and sport, types of diets; high fruits and vegetables and healthy eating out at restaurants, arterial blood pressure; lack of routine BP check and known HPT and types of ARVS used in HIV/AIDS therapy.

- Description: There has been a large amount of research on infidelity and its effects on relationships. However, a new phenomenon, that of online infidelity, has emerged and with it comes some confusion as to what exactly constitutes an act of infidelity while exploring the limits of cyberspace. While some research has been done internationally on the perceptions of online infidelity, studies conducted in South Africa are lacking. The aim of the present study was to explore and describe student perceptions of online infidelity. Social Constructionism was used as the theoretical framework for the study. A qualitative approach was used and the study was exploratory and descriptive in design. Semi-structured interviews were conducted, with the sample size of the study being twelve. Thematic analysis, as outlined by Braun and Clarke, was used in order to analyse the obtained data. Two main themes emerged, namely Defining Online Infidelity, and Reasons Surrounding Perceptions of Online Infidelity. The findings of the present study will provide a better understanding of perceptions of online infidelity within the South African context, and can be used for further research.

- Description: In the last decades, there has been an escalating consumption of antibiotics with the number of antibiotic prescriptions increasing worldwide. Overuse or inappropriate use of antibiotics has resulted in a major increase in the development of multi-drug resistant pathogens. Antimicrobial resistance is one of the world’s most serious public health problems with great implication in terms of morbidity, mortality, and costs. To date, there has been no formal antibiotic use study conducted in the West Wollega zone of Ethiopia to assess antibiotic utilization. The objective of this study was to determine the pattern of antibiotic use in two hospitals in the West Wollega zone of Ethiopia, namely Gimbie Adventist Hospital and Nedjo Hospitals, using drug utilization metrics and the costs associated. In addition it was to assess the correlation between diagnosed infectious diseases and antibiotic prescriptions. This study was a cross-sectional, retrospective, descriptive review of antibiotic usage in the two hospitals in the year 2007. Prescriptions dispensed in the first month of each quarter of 2007 were reviewed. The number of prescriptions screened, antibiotic courses started, antibiotic days by specific agent and overall, the cost of individual and all antibiotics, the number and type of infectious diseases diagnosed were collected from which core drug use indicators were calculated. The correlation between infectious disease diagnosed and the antibiotic days prescribed were analyzed. A total of 18568 antibiotic and non-antibiotic prescriptions were reviewed retrospectively in the four months of the study period, 47 percent of which contained at least one antibiotic. The average number of antibiotics per prescription was 1.33 and 1.09 whilst the percentage of injectable antibiotics prescribed was 83.2 percent and 3.76 percent to outpatients and inpatients respectively. Antibiotics prescribed from the Essential Drug List (EDL) and List of Drugs for District Hospital (LDDH) were 63.0 percent, 74.8 percent, and 90.8 percent and 76.1 percent for outpatients and inpatients respectively. 98.6 percent of outpatient and 97.0 percent inpatient prescribed antibiotics were actually dispensed. Penicillins and quinolones were the most prescribed antibiotics in both inpatient and outpatient departments constituting 43.46 percent and 24.08 percent respectively. The antibiotic utilization ratio, incidence of outpatient antibiotic use, incidence of inpatient antibiotic use, the number of Defined Daily Doses (DDD)/1000inhabitants/year and DDD/100 Occupied Bed Days (OBD) for the zone was 0.16, 17.25, 23.56, 158.61, and 70 respectively. Antibiotic cost constituted 33.7 percent of all expenditure on drug, cost of antibiotic per patient care day and cost per antibiotic day was 3.84 Ethiopian Birr (ETB) ($0.40) and 6.29 ETB ($0.66) respectively. The correlation between infectious diseases diagnosed and antibiotic prescription shows significant variation. At outpatient departments alone an average number of antibiotic courses started was 2.7 at Gimbie Adventist Hospital and 7.6 for Nedjo Hospital. When overall antibiotic days prescribed and required was compared in both hospitals, there were 2.4 and 5 times more antibiotic days prescribed than were required for Gimbie and Nedjo Hospitals respectively. This suggests that the overuse of antibiotic is worse in the government hospital (Nedjo Hospital) than in the mission hospital (Gimbie Adventist Hospital). This study suggested that there was overuse of antibiotics in the West Wollega hospitals although further investigation is needed to identify its underlying causes and nature. It is recommended that the health personnel, the hospital management, the zonal and regional Health Bureau, the regulatory bodies and Non-Governmental Organizations (NGOs) work hand-in-hand to promote the rational use of antibiotics in this region so that the consequences and financial cost of antimicrobial resistance can be prevented.

- Description: Job satisfaction and motivation play an important role in job retention and increased productivity of pharmacists which in turn improves pharmaceutical care performance. Pharmacies in Port Elizabeth have an increased pharmacist shortage and many community or retail pharmacies must overcome challenges to retain pharmacists. The study was quantitative in nature. A descriptive and exploratory approach was used. The research objective was to conduct a questionnaire survey of pharmacists working in community pharmacies in Port Elizabeth to assess the levels of job satisfaction and report the findings with recommendations to management. A modified Job Descriptive Index questionnaire was used to determine the level of job satisfaction. The variables used to determine the level of satisfaction was job content, monetary remuneration, promotion, co-workers, and supervision. Retention strategies was used to determine effective strategies managers can use to retain pharmacists. Positive and negative aspects of community pharmacy was also determined. A total of 48 pharmacies were approached by the researcher, 27 questionnaires were distributed to eligible participants which met the inclusion criteria and 23 questionnaires was returned, thus giving a response rate of 85%. It was observed that job satisfaction was positive in areas of job experience or content, customer interaction, interpersonal relationship with co-workers and supervision. The areas of job dissatisfaction were monetary remuneration and promotional opportunities. The retention strategies which received the most effective score were competitive financial packages (87%) and personal development (86%). The means of the retention strategies were high and even closer to 5 which indicated the “most effective” score. The pharmacists were not satisfied with monetary remuneration, promotion, recognition and performance appraisal provided by the organisations. The pharmacists are feeling over burden towards the workload. Management in this regard should pay attention to findings.

- Description: Background: The steady increase in deaths due to non-communicable diseases (NCDs) in South Africa is raising concern, as 63% of all deaths worldwide are attributed to NCDs and these diseases cause 36 million deaths each year, with 80 % of incidences occurring in low-and middle-income countries. In rural communities where income is increasing, the prevalence of NCDs are increasing as well. Due to the lack of NCD prevention and treatment in rural communities, it is expected that, if health promotion strategies are not implemented and socio-economic development in South Africa continues, there will soon be an uncontrollable NCD epidemic. It has been found that dietary risks affected people’s healthirrespective of their age, gender or residential sociodemographic development and that dietary improvement might prevent one in every five deaths worldwide.Aim:The aim of this study was to determine the factors that influence the perceptions and behaviour in a rural community with a low socio-economic status regarding dietary habits and to use the knowledge to formulate an effective dietary modification strategy.Designand methodology:For this study,action research with a quantitative and qualitative component was followed.The quantitative component focuses on measureable aspects, and the qualitative component focuses on meaning. Data was collected following the standard operating procedure for anthropometry, blood pressure and blood glucose. Further methods used were questionnaires, 24-hour dietary recalls and focus group discussions. Data were analysed using Microsoft Excel, FoodFinder3 and other calculations.Sample and setting:A convenience sample (n = 16) wasused and this study was undertaken on request of the non-governmental organization, Karoo Angels and included all participants who earn an income and who do not work for themselves, that were willing to participate and living in Rietbron and Vondeling, in the Sarah BaartmanDistrict in the Eastern Cape. Results:Weight changes took place, both the crafters in the mild thinness category gained weight, one gained 3.9 kg and the other 0.5 kg. The three crafters in the normal category did not have to gain or lose weight, but all three ofthem gained an average of 3.6 kg. For the group who had to lose weight, no statistically significant weight change took place from before the intervention (76.08 ±17.67 kg) to after the intervention (75.81 ± 17.81 kg, t(10) = 0.692, p = 0.505). The maximum weight lost ivwas 3.1 kg and the maximum weight gained was 3.2 kg. Changes took place regarding BMI, waist circumference, waist-to-hip ratio and neck circumference. Some positively changed their BMI status.After the implementation of the intervention, there was a slight decrease in frequency of alcohol consumption, but smoking and physical activity remained mostly the same. Hypertension was the most prevalent NCD and is linked to smoking and alcohol consumption which is prevalent in this study. Fruit and vegetable consumption is low, and a slight increase in consumption was evident. A maximum dietary diversityscore of seven and minimum of two, where the mean was 3.81was found. The crafters’ diet did not meet the DASH diet recommendation,the mean energy distribution is of all macronutrients differ with ±4% and none of the participants’ mean micronutrients intake met the recommendations of the DASH diet or RDA. Factors that prevent them from reaching their goals included low income, low availability of fruit, vegetables and transport and no storage for food.Conclusion:It is important to consider the individuals’ living conditions, resources, knowledge, motivation and social group. The environment and resources available have a significant impact on the lifestyle of the individuals. Directing efforts of behaviour change to increase dietary diversity as the main objective, might be a more efficient way to change behaviour.Recommendations:Future studies should consider doing this study over a longer time period. The involvement of a psychologist would also be beneficial to assist the process of behaviour change.

- Description: Background: Globally, childhood mortality remains high with 5.3 million deaths occurring in children under the age of five years in 2018. Of these deaths, 43 000 were children from South Africa, with malnutrition being a significant risk factor contributing to disease and death. Breastfeeding has many benefits and reduces childhood mortality. Current primary health care strategies in South Africa are not having an adequate impact on breastfeeding rates, therefore appropriate messages need to be targeted at the community in order to improve breastfeeding rates. Participatory approaches have been identified as an effective tool to promote child health. Community dialogues led by skilled Early Childhood Development (ECD) mentors from the community might be key in order to improve caregivers’ knowledge, attitudes and practices (KAP) in relation to breastfeeding and Prevention of Mother to Child Transmission of HIV (PMTCT). Aim : The aim of the study was to explore the potential effects of community dialogues, led by ECD mentors, on caregivers’ knowledge, attitudes and practices (KAP) in relation to breastfeeding and prevention of mother-to-child transmission of HIV (PMTCT). Methods: Quasi-experimental design was used to compare the KAP of caregivers in relation to breastfeeding and PMTCT. Convenience sampling was used to include 63 caregivers who participated in the umbrella project (mixed-methods) and 61 caregivers who did not participate in the project. Ethics approval was obtained from the Nelson Mandela University Faculty Postgraduate Studies Committee. Participants had to provide written informed consent. A skilled interviewer used a structured questionnaire to assess the KAP of all participants. Data were captured on an Excel spreadsheet and analysed in collaboration with a statistician, who analysed the data using Microsoft Excel. Descriptive statistics were applied to numerical data, while frequency distributions were applied to categorical data. Correlations were calculated to describe the degree of relationship between two variables. Inferential statistic tests, conducted at a significance level of 0,05, were used for hypothesis testing. The t-test and analysis of variance (ANOVA) were used in tests involving mean values. Scheffé’s test was used in ANOVA to determine between which of the groups a statistically significant difference was found. Results: In the intervention group more than double the number participants (35%; n=22) had a good knowledge of breastfeeding when compared to participants (15%; n=9) in the control group. Additionally, the intervention group participants displayed better attitudes towards the RtHB (p=0.02). However, control group participants showed better knowledge towards the HIV (p=0.01). Finally, results suggest that in the intervention group, participants (33%; n=21) were more likely to have a good total KAP score in relation to breastfeeding and PMTCT when compared to participants (11%; n=7) in the control group. In the intervention group, better knowledge correlated with good practices relating to the RtHB (r=0.27). However, in the control group, positive attitudes correlated with better practices relating to HIV (r=0.29). Younger intervention group participants displayed better breastfeeding related practices (p=0.011). Additionally, younger control group participants displayed better knowledge of breastfeeding (p=0.001). Intervention group participants whose choices were influenced by their husband/ partner (p =0.016) and/ or radio/ magazines/ newspapers (p=0.004) had positive attitudes towards HIV. Control group participants whose choices were influenced by their other family members (p=0.043) and/ or clinic staff (p=0.016) had good knowledge of sharing their knowledge. Conclusions and recommendations: The intervention group displayed a better knowledge of breastfeeding as well as more desirable attitudes towards the RtHB, when compared to the control group. However, the control group displayed better knowledge of HIV, which could be due to the control group having more younger participants when compared to the intervention group. The community dialogue intervention had a positive impact on caregivers KAP relating to breastfeeding and PMTCT, which included all the different categories combined. In order to improve the Sakha Esethu intervention programme, managers need to provide guidance to the mentors on how to initiate conversations regarding HIV and discuss the stigma associated with HIV and breastfeeding. Results showed that including grandmothers and husbands or partners in the target population will benefit the intervention. Additionally, the use of radio needs to be considered especially for discussions regarding HIV. Lastly, sustainability needs to be improved due to many participants not remembering certain detail regarding topics that was discussed. , Thesis (MSc) -- Faculty of Health Sciences, 2021

Convenience sampling was used to include 63 caregivers who participated in the umbrella project (mixed-methods) and 61 caregivers who did not participate in the project. Ethics approval was obtained from the Nelson Mandela University Faculty Postgraduate Studies Committee. Participants had to provide written informed consent. A skilled interviewer used a structured questionnaire to assess the KAP of all participants. Data were captured on an Excel spreadsheet and analysed in collaboration with a statistician, who analysed the data using Microsoft Excel. Descriptive statistics were applied to numerical data, while frequency distributions were applied to categorical data. Correlations were calculated to describe the degree of relationship between two variables. Inferential statistic tests, conducted at a significance level of 0,05, were used for hypothesis testing. The t-test and analysis of variance (ANOVA) were used in tests involving mean values. Scheffé’s test was used in ANOVA to determine between which of the groups a statistically significant difference was found. Results: In the intervention group more than double the number participants (35%; n=22) had a good knowledge of breastfeeding when compared to participants (15%; n=9) in the control group. Additionally, the intervention group participants displayed better attitudes towards the RtHB (p=0.02). However, control group participants showed better knowledge towards the HIV (p=0.01). Finally, results suggest that in the intervention group, participants (33%; n=21) were more likely to have a good total KAP score in relation to breastfeeding and PMTCT when compared to participants (11%; n=7) in the control group. In the intervention group, better knowledge correlated with good practices relating to the RtHB (r=0.27). However, in the control group, positive attitudes correlated with better practices relating to HIV (r=0.29). Younger intervention group participants displayed better breastfeeding related practices (p=0.011). Additionally, younger control group participants displayed better knowledge of breastfeeding (p=0.001). Intervention group participants whose choices were influenced by their husband/ partner (p =0.016) and/ or radio/ magazines/ newspapers (p=0.004) had positive attitudes towards HIV. Control group participants whose choices were influenced by their other family members (p=0.043) and/ or clinic staff (p=0.016) had good knowledge of sharing their knowledge. Conclusions and recommendations: The intervention group displayed a better knowledge of breastfeeding as well as more desirable attitudes towards the RtHB, when compared to the control group. However, the control group displayed better knowledge of HIV, which could be due to the control group having more younger participants when compared to the intervention group. The community dialogue intervention had a positive impact on caregivers KAP relating to breastfeeding and PMTCT, which included all the different categories combined. In order to improve the Sakha Esethu intervention programme, managers need to provide guidance to the mentors on how to initiate conversations regarding HIV and discuss the stigma associated with HIV and breastfeeding. Results showed that including grandmothers and husbands or partners in the target population will benefit the intervention. Additionally, the use of radio needs to be considered especially for discussions regarding HIV. Lastly, sustainability needs to be improved due to many participants not remembering certain detail regarding topics that was discussed. , Thesis (MSc) -- Faculty of Health Sciences, 2021

- Description: This study explored and described the perception of clinical psychologists regarding thebarriers to the provision of psychological services in urban public health settings for people with first-episode schizophrenia. The qualitative research study utilised an explorative, descriptive interpretive research design. Purposive sampling was utilised to gain access to clinical psychologists, who had at least two years of public health experience working with people recently diagnosed with schizophrenia. Data was gathered from 11 participants from the Nelson Mandela Bay Health District of the Eastern Cape by means of in-depth interviews that were conducted in English by the researcher until data saturation had occurred. A computer-assisted qualitative thematic analysis of the collected data was conducted using NVIVO software. The findings have been categorised according to three broad domains: 1)contextual barriers 2)health care system-related barriers and 3)first-episode schizophrenia syndrome-related barriers. Several specific sub-themes were identified for each of these main domains allowing for recommendations and suggestions to be provided for attending to and overcoming these perceived barriers.
