- Description: In 1981, a number of reports of death from immune system failure began to cause alarm in medical circles. The Human Immunodeficiency Virus (HIV) was identified as the cause of a condition known as Acquired Immune Deficiency Syndrome (AIDS). To date, there is no cure for AIDS, and as a result it is perceived as the deadliest medical condition of the century. While intensive research remains focused on development of a vaccine, there has been a strong move toward a more preventative approach that is holistic in nature, and encompasses behavioural and social components as being of equal importance. Going hand in hand with HIV/AIDS are Sexually Transmitted Infections (STIs). STIs are increasing around the world and in South Africa at a remarkable rate. Like HIV/AIDS, STIs are also transmitted during sex, more specifically through body contact during sex. Research has identified adolescents as a group that is particularly vulnerable to HIV and STI infection. Life-skills programmes use experiential learning to engage learners and are particularly popular because they empower individuals to make responsible, well thought out decisions based on well developed values and beliefs. There are however, various variables and agents that impact upon the success of HIV/AIDS and STI education. It is therefore suitable to adopt a biopsychosocial approach to underlie a HIV/AIDS and STI life-skills programme. Health models, such as the AIDS Risk Reduction Model, based on this approach should take into consideration important psychological variables to cope with changes in behaviour, as well as prepatory behaviours inclined towards preventing risky behaviour. The Ubuntu Education Fund is a non-government, international organisation that offered a life skills programme in HIV/AIDS, STIs, Rape and Child Abuse to learners in Grades 6 - 9. This study focused on HIV/AIDS and STIs. The sample size was 260 learners from the Nelson Mandela Metropolitan Region. A quasiexperimental one group pre-and post-test design was used to determine if there was a difference between the knowledge of these learners pre- and post- the life skills programme. The results of the study indicate that there was a small increase in knowledge after the life-skills programme intervention. In some schools there was even a decrease in knowledge. This study suggests that the life-skills programme was flawed and that it needs to be reviewed. The implications of these findings are discussed with suggestions for future interventions.

- Description: Metronidazole is a synthetic, nitroimidazole-derivative antibacterial and antiprotozoal agent (ed. McEvoy, 2001). It has been reported that crystallization occurs in aqueous suspensions of metronidazole benzoate, a bland-tasting prodrug of metronidazole, as a result of conversion from the anhydrous to the monohydrate form, thereby compromising the stability and clinical efficacy of the substance due to the particle size growth (Hoelgaard & Moller, 1983). A generic South African based pharmaceutical company commenced formulation of an aqueous metronidazole benzoate suspension and experienced problems with crystallization that occurred in products stored at 2 to 8 °C. This study aimed to continue development of the product in order to identify a formulation that prevents formation of the hydrate form of metronidazole benzoate and the accompanying crystal growth. A variety of metronidazole benzoate suspensions were manufactured on a laboratory scale using a number of natural and synthetic suspending agents, including magnesium aluminium silicate, povidone K90, xanthan gum and Avicel® RC-591 (microcrystalline cellulose and carboxymethylcellulose sodium), over a range of concentrations. Analytical quantification methods were developed and validated, and the physicochemical properties of the raw material and finished products were fully characterized. Rheological tests were performed in order to characterize the suspension flow properties. Real-time and accelerated stability studies and a temperature cycle study were conducted in accordance with the International Conference on Harmonization (ICH) guidelines. Conversion of metronidazole benzoate to the monohydrate form took place in suspensions containing xanthan gum 0.65 percent m/v under real-time and accelerated storage conditions. The suspensions containing Avicel® RC-591 were found to be physically and chemically stable after the temperature cycle and over the 12-week period whilst stored at 25 ºC / 60 percent RH and 5 ºC. The suspensions were chemically stable whilst stored at 40 ºC / 75 percent RH but showed sedimentation at this accelerated condition. The metronidazole benzoate contained in these products remained in the anhydrous state under all storage conditions and were consequently concluded to be the most stable formulations out of all the products analyzed in the current study. The suspending agent system consisting of microcrystalline cellulose and carboxymethylcellulose sodium thus shows promise in preventing the conversion of metronidazole benzoate from the anhydrate to the monohydrate form, thereby inhibited the subsequent increase in particle size due to crystal growth.

- Description: Traditional medicine has a long history of being used for treating various ailments ranging in severity. Although traditional medicine has typically been the health care for the poorest levels of society, there is a worldwide growth in popularity. The growing popularity of traditional medicine, termed the green boom, may be ascribed to people taking a more holistic approach to maintain their health. Traditional medicine is widely used on a regular basis by 70% of South Africans. Various indigenous medicinal plants are used for the preparation of traditional herbal medicine. These plants are mostly indigenous to the regions were it is used. In this study four medicinal plants (Bulbine frutescens, Leonotis leounurus, Melianthus major & Zantedecshia aethiopica) that are traditionally used in the Eastern Cape region for treating burn wound infections, were collected for investigation. The in vitro antibacterial activity of these plants was tested against different bacterial strains of eight different bacteria. The bacteria used in this investigation included bacterial strains of four Gram-positive bacteria, S. aureus, methicillin-resistant S. aureus (MRSA), E. feacalis, S. pyogenes and four Gramnegative bacteria, P. aeruginosa, A. baumanii, K. pneumoniae and P. mirabilis. Traditional preparations as well as three different extracts (methanol, aqueous & acetone) of the plants were used for in vitro antibacterial activity testing. The microtitre plate assay and agar dilution assay were used for determining the antibacterial activity of the traditional preparations and plant extracts against the different bacterial strains. In the microtitre plate assay the antibacterial activity was tested using the bacterial growth indicator, INT and a microtitre plate spectrophotometer to determine the minimal inhibitory concentrations of the plant extracts and traditional preparations. The microtitre plate assay was used for testing the antibacterial activity of the plants against the bacterial strains of five bacteria, S. aureus, MRSA, P. aeruginosa, A. baumanii and K. pneumoniae. The bacterial strains of the three bacteria, S. pyogenes, E. feacalis and P. mirabilis were not compatible with the microtitre plate assay using INT and spectrophotometric readings to determine bacterial inhibition. Therefore the agar dilution assay were used as an alternative method for determining the MIC’s of the plant extracts against the bacterial strains of these bacteria. The initial plant extract concentration in the microtitre plate assay differed with the different plant extracts in the microtitre plate assay. Acetone followed by methanol extracted the highest plant extract concentrations with the different medicinal plants. M. major followed by L. leonurus produced the highest plant extract concentrations following extraction with the different extraction solvents. Consequently the acetone extract of M. major had the highest plant extract concentration before serial dilution in the microtitre plate assay. Uniform plant extract concentrations were tested in the agar dilution assay. The methanol extract followed by the acetone extract of the plants gave the highest antibacterial activity against the different bacterial strains. The extracts of M. major followed by L. leonurus inhibited the highest number of bacterial strains in the microtitre plate assay and the extracts of B. frutescens inhibited the lowest number of bacterial strains. The acetone and methanol extracts of M. major were the only extracts that displayed antibacterial activity in the agar dilution assay. The bacterial strains of P. mirabilis were the only bacteria that were inhibited using this method. The bacterial strains of S. pyogenes and E. feacalis were not inhibited at any of the plant extract concentrations in the agar dilution assay.

- Description: The purpose of this study is to investigate specific contributing factors affecting quality assurance in the diagnosis of conventional cervical smears. More than half of South- African women fail to have one cervical smear in their lifetime and +/- 50 percent of those who do have cervical smears taken, are lost to follow-up. Since cervical cancer is the most common malignancy amongst women in developing countries, the medical profession will have to endeavor to screen a higher rate of women and ensure a 100 percent quality assurance with every patient treated in order to reduce the unacceptable high incidence of cervical carcinoma. At this stage it seems like an impossible task to screen all women in South Africa, due to far-off rural areas, shortage of medical professionals and the lack of knowledge of some women of the necessity of cervical smears. Many newly qualified South-African doctors leave the country to go and work elsewhere. South Africa then in turn has to recruit doctors from other countries to staff the State hospitals and clinics. Some areas have one doctor to thousands of patients, insufficient nursing personnel and inadequate equipment. Doctors in some areas cannot cope with the volume of work and the long hours. One has to accept that the quality of the management of some patients is affected negatively. There are a number of medico-legal issues (world wide) in relation to aspects of cervical cancer prevention practices which are controversial and are of particular concern to all of those involved in cervical cancer prevention. Various countries have therefore formed different national organizations to address the medico-legal issues in screening for the prevention of cancer. These organizations monitors procedures, internal quality control as well as external quality control. In South Africa, medico-legal cases are not so prevalent, but may become so shortly. The South-African medical professionals therefore have to ensure that their quality of work conforms to accepted good practice in all circumstances. State hospitals serve thousands of patients per month and it is an every day occurrence to see long queues of patients sitting waiting for doctors and who often have to come back the following day. The situation appears to be much improved in private practice and since patients have medical cover and accessible medical facilities. Since cervical cancer is the most common malignancy amongst women in developing countries, the medical profession will have to endeavor to screen a higher rate of women and ensure a 100 percent quality assurance with every patient treated in order to reduce the unacceptable high incidence of cervical carcinoma. At this stage it seems like an impossible task to screen 100 percent of women in South Africa, due to far-off rural areas, the shortage of medical professionals and ignorance of patients. Quality assurance is therefore of paramount importance to every medical professional for every patient treated. Laboratories all worldwide have been, or are in the process of being accredited by their specific accreditation authorities. The main reason for this is improvement of quality control and therefore quality assurance. The South African National Accreditation Society (SANAS) now accredits various laboratories in South Africa with the view of accreditting all laboratories within a certain time limit. The Ampath laboratory Port Elizabeth was successfully accredited during 2001. Accredited laboratories have to uphold a very high degree of quality to remain accredited. A team of professionals inspects the laboratory every 2 years and other quality assurance staff inspects the laboratories every few months. All aspects of the laboratory are checked, e.g. the qualification of staff, their registration with the Health Professions Council of South Africa (HPCSA), their curriculum vitaes, equipment, safety of the laboratory etc. Since the laboratory chosen for this study, is accredited, the author evaluated every cervical smear that was received in the laboratory since the year 2000, with the following objectives in mind: · Whether the presence or absence of an endocervical component has an effect on the adequacy of cervical smears · To determine the effect of using smaller coverslips on quality assurance in the cytology laboratory · Evaluate the effect that manual re-screening of smears has on quality assurance in the cytology laboratory. As there is a shortage of cytotechnologists and pathologists worldwide, several countries make use of automated screening devices as primary screening or secondary screening for quality assurance. These devices were tested in some laboratories in South Africa but were found to be very expensive and sensitivity and specificity were not up to standard. Sensitivity is a measure of the ability of a test to detect the abnormal - Sensitivity is the ratio of true positives to true positives + false negatives. Specificity is a measure of the ability of a test to correctly identify the negative - Specificity is the ratio of true negative to true negatives + false positives. The automated screening machines failed to identify abnormal cells amongst inflammatory cells, as well as in very blood stained smears. Several other problems also occurred and an increasing number of smears had to be manually rescreened, thus making this exercise costly and not helpful as a quality assurance instrument. The slides used for this thesis, have been retrieved from the archives of the Ampath laboratory in Port Elizabeth. Fourteen specific contributing factors affecting quality assurance in the diagnosis of cervical smears are also discussed and conclusions and recommendations given.

- Description: This study aimed at exploring the developmental profile of HIV positive/AIDS infants and children (three to 35 months) over a period of 11 months in the Nelson Mandela Metropole, utilising the Revised Extended Griffiths Scales of Mental Development (GSMD). The purpose was to generate information about the development of HIV positive/AIDS infants and children, highlighting developmental strengths and weaknesses to ultimately aid the custodians of these children with their interventions. A non-probability purposive sampling method was applied, and a longitudinal profile was generated as participants were assessed twice. Participants were all outpatients at Kwazakhele Day Clinic, Dora Nginza and Livingstone Hospitals in the Nelson Mandela Metropole, and were located for the study through their caregiver’s attendance of an HIV support groups at the Dora Nginza Hospital. Data was analysed statistically using descriptive statistics and Hotelings-T² tests. Results indicated a significant difference between first and second assessment on the General Quotient and on two of the six subscales, namely Eye-Hand Co-ordination (D) and Practical Reasoning (F). It was deduced that development declined or did not improve as participants aged.

- Description: Due to the early age at which children are exposed to rape and child abuse, preventative programs should be implemented as early as possible. Schools provide ample opportunity to reach learners of all ages. Educators have regular contact with learners and have a key role to play in the implementation of comprehensive health and education life skills programs. Non-Governmental Organisations (NGO) can link up with schools to combat abuse that affects children in South African communities. The Ubuntu Education Fund requested the Health and Development Research Institute (HDRI) of the University of Port Elizabeth to assist with the evaluation of the Mpilo-Lwazi life skills program for grade 6 to 9 learners at 5 primary and 5 secondary schools in the Nelson Mandela Metropole. The schools were selected by non-probability convenience sampling and the learners via simple random sampling. The life skills program addressed issues of HIV/AIDS, STI and rape and child abuse and the requested evaluation encompassed both the quantitative pretest-posttest assessment of knowledge plus a qualitative focus group assessment of perception of the content and presentation of the life skills program. A multiple pretest-post-test quasi-experimental research design was used. This study focused on the quantitative aspect of rape and child abuse and aimed to describe learners’ base line knowledge before receiving education in rape and child abuse life skills programs and acquired knowledge after the program had been implemented. Descriptive statistics were employed to describe the pre and post test information and the Hotelling’s T2 was used to identify variation in profiles. Posthoc t-tests established significant differences between grades. Structured questionnaires were used to achieve the aims of the research. Results of both the quantitative and qualitative findings were collated to be presented to the Ubuntu Education Fund. The results of the study were as follows: ix The results indicated that the overall level of knowledge regarding Rape and Child Abuse among the sample of grade six to nine learners was average. A small increase in knowledge was identified in the post-test. The area most successful for knowledge increase was the section relating to general information on the victims of Rape and Child Abuse. An area where knowledge actually decreased was that on reporting the rape or abuse. Knowledge of rape and child abuse alone is not sufficient to bring about change in behaviour. Changes in beliefs, such as increased awareness that rape and child abuse are prevalent in families and communities, and attitude change are necessary to facilitate the adoption of health-promoting behaviour. Future education efforts need to introduce health educators into the Rape and Child Abuse life skills program at schools in educating the learners. The format of teaching should also take into account the preferred method of presentation indicated by the learners as this would facilitate optimal intake of information.

- Description: Due to the early age at which children are exposed to rape and child abuse, preventative programs should be implemented as early as possible. Schools provide ample opportunity to reach learners of all ages.

- Description: This study aims to discover the meaning that primary school children place on the loss of a parent and the impact it has on the children’s lives. As it is an emotive topic, and because of the difficulties of interviewing children, qualitative techniques of research data collection are considered the most appropriate. The study will explore, discover and describe children’s personal experiences of loss in a phenomenological and contextual manner. The sample in the study will be selected according to non-probability and purposive sampling techniques. Because children are being interviewed, the researcher will ethically approach gatekeepers for permission, and gain their informed consent. Data will be collected using semi-structured interviews, in which the researcher will interact with the interviewees in a natural setting. Data analysis will be done according to Tesch’s eight steps for analysing qualitative research data (Creswell, 1994:155). Once this process has been completed, the data will be verified against the four criteria that Guba (in Krefting, 1991:214-222) developed for testing the trustworthiness of qualitative research findings. The results of the study, as well as conclusions and recommendations drawn from the data, will be disseminated by means of a written report.

- Description: From a social constructionist perspective, the self of the therapist is the only tool that she takes into therapy with her. The study of the therapeutic self therefore becomes important as this impacts on the quality of therapy received by the client. This treatise explores the development of the researcher’s therapeutic self through the storying of significant learning experiences in the course of her training in counselling psychology. An analysis of the narrative reveals the substance of some of the soul tattoos that make up her therapeutic self. The study was undertaken from an action research approach, thus emphasising the investigation of the therapeutic self in the field and feeding this information back into the practice of counselling psychology in the course of the research project. The themes extracted in the analysis reveal the process of action learning and what constituted significant learning experiences for the researcher. The researcher found that certain conditions were required for the formation of soul tattoos and that merely obtaining a masters degree in counselling psychology was not sufficient preparation for the practice of counselling psychology.

- Description: The changes that have taken place in the South African educational system over the past few years have placed teachers under increasing stress. While abundant overseas literature is available regarding teacher stress, limited studies have focused specifically on South African samples. Female teachers, and working mothers, often experience additional stressors to men. Studies on women’s health have received little attention in comparison with the magnitude of research conducted on men’s health. The aim of the current study was to explore and describe the stress, coping resources and adjustment of married mothers in the teaching profession, and to explore and describe the patterns of stress and coping resources of these women. A non-experimental, exploratory descriptive study was employed. A biographical questionnaire and three paper-and-pencil measures, namely the Experience of Work and Life Questionnaire, the Coping Resources Inventory and the Personal, Home, Social and Formal Relations Questionnaire, were administered to 31 full-time primary school teachers who are married mothers of dependent children under the age of 14 years. A non-probability convenience sampling technique was employed. Descriptive statistics and cluster analysis were used in the data analysis. The results of the WLQ for this sample indicated that the mean score for the total level of stress fell within the high range, but with regards to the mode, the majority of the participants had average scores. The results of the CRI indicated an average level of coping resources for the present sample. The sample scored slightly above average on seven of the eleven components of the adjustment areas of the PHSF and slightly below average on the other four components. The participants in cluster one had average levels of stress and an average level of coping resources. The participants in cluster two scored very high levels of stress and average levels of coping resources. The participants in cluster three had very high levels of stress and low levels of coping resources. Suggestions were made for future research involving the stress, coping resources and adjustment of married mothers in the teaching profession. Finally, the limitations as well as the value of the research were outlined.

- Description: There has been a shift in the South African education system from a purely grade-oriented system to that of a learner-centred outcome-based system of education which challenges higher educational institutions and their faculties to adjust their goals to this system. In South Africa there is evidence of poor academic performance at higher education institutions. Among other things, noncognitive factors may be important mediators of academic success. With the expansion of higher education and the increased emphasis on access, retention and life-long learning, it is a good reason to explore the nature of different learning styles (Healey & Jenkins, 2000). Learning styles and personality types has been identified as significant predictors of academic performance. The present study aimed to contribute to this body of research in general and to Kolb’s (1981) theory of experiential learning and his conceptualisation of learning styles in particular. The aims of the study were to explore and describe the learning styles of first year university students (Aim 1), to explore and describe the learning styles of first year university students per faculty (Aim 2), and to explore the relationship between learning styles and academic performance for students in the various faculties (Aim 3). The study used an explorative descriptive and correlational research method and was conducted within a quantitative framework. Participants were selected using a non-probability convenience sampling technique. The sample was comprised of 391 first year university students to whom Kolb’s Learning Style Indicator was administered as part of the Explore programme during orientation week. Descriptive statistics were used in order to explore and describe the learning style of the learners for the sample as a whole and per faculty. Data for the learning styles and academic performance categories were cross tabulated so as to comment on the relationship between learning styles and academic performance per faculty. Small cell sizes made it impossible to analyse the latter data statistically. Across the six faculties the Accommodator learning style was the most represented, followed by the Diverger learning style. No significant relationship was found between learning styles and academic performance. The implications of the findings for counselling and teaching students are highlighted and suggestions to expand the research through using larger samples are also made.

- Description: Worldwide millions of children are victims of neglect and physical and mental harm, including sexual abuse and exploitation. South Africa, however, is widely believed to have not only one of the highest incidences of rape in the world, but also one of the highest levels of Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) transmission. With research findings showing that HIV and other Sexually Transmitted Infections (STIs) are rapidly increasing globally, young people are, and continue to be, at the forefront of the AIDS pandemic. Therefore, it is suggested that prevention programmes should be aimed particularly at the young. Schools have specifically been recognized as the setting for preventative Life Skills Programmes, having the potential to reach billions of children worldwide. The aim of this study is to explore and describe the perceptions of grade eight and nine learners with regard to the Life Skills Programme that focuses on HIV/AIDS and STI's, rape and child abuse education in the Port Elizabeth region. In order to fulfil the above aim, a qualitative study was undertaken within an exploratory descriptive approach. A non-probability sample of four schools was selected. Focus groups, utilising an unstructured interview, were used to gather qualitative data on the learners' perceptions of the Life Skills Programme. The focus groups consisted of 10 - 12 grade eight and nine learners who were selected using simple random sampling. The data was thematically analysed using Tesch's approach. The major findings of the present study, based on the six general themes, include the following: 1. Most of the learners perceived the educators, as well as the teaching methods utilised by the educators, positively. 2. Although the learners perceived the presenters of the Life Skills Programme positively, it was suggested that teachers, health care professionals, family members and peers should be involved in presenting the Life Skills Programme. 3. Learners reported various levels of comfort discussing different topics presented in the Life Skills Programme. 4. Learners of all the schools perceived the Life Skills Programme to be very relevant. 5. Learners recommended that more children, especially children from deprived communities, should be included in the programme. In addition, learners felt that counselling services should be available in conjunction with the Life Skills Programme. 6. Differences were noted in completing the first and the second questionnaire. Learners reported that they felt more comfortable completing the second questionnaire. They perceived the interviewing process positively.

- 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.

- Description: The South African context necessitates developmental assessment measures with particular characteristics. A critical examination of a variety of potential measures indicates that there are very few measures available to meet these specific needs. The GMDS-ER is judged to be one such measure. This study explores the performance of South African children aged 4 to 7 years of age as it relates to that of British children (from the standardisation sample). The samples consisted of normal South African (n=129) and British (n=161) children, where normalcy refers to the absence of sensory, physical, or mental handicap. The study was done in an attempt to explore the suitability of using the GMDS-ER in the South African context. More specifically, the following two aims were pursued: 1. To explore and describe the general development of each of four year groups of a sample of British and South African children by utilising the general developmental quotient of the GMDS-ER 2. To explore and describe the comparative developmental profiles of each of the four year groups of a sample of British and South African children across the six developmental areas represented by the subscales of the GMDS-ER. Descriptive statistics and simple t-tests were used to accomplish Aim 1 and Hotellings T2 tests were mainly used in order to accomplish Aim 2. The major findings of the present study were as follows: 1. South African and British children’s overall performances (as measured by the GMDS-ER GQ) are similar. A great deal of variability exists between the GMDS-ER profiles of normal South African and British children (i.e., when individual subscales and year groups are considered). 3. In general, South African children performed better on the Locomotor and Personal-Social Subscales, while British children performed better on the Language and Practical Reasoning Subscales. Performance on the Eye and Hand Coordination Subscale was similar for the two samples and on the Performance Subscale performance was too variable to come to any general conclusions. In view of the findings, caution with regard to the use of the British-based norms in the South African context is recommended. Recommendations are made for the use of the GMDS-ER to help with the identification of specific classes of disorders in the South African context. Further investigation into the applicability of the GMDS-ER for South African use as well as the establishment of South African norms are final recommendations.

- Description: The South African context necessitates developmental assessment measures with particular characteristics. A critical examination of a variety of potential measures indicates that there are very few measures available to meet these specific needs. The GMDS-ER is judged to be one such measure. This study explores the performance of South African children aged 4 to 7 years of age as it relates to that of British children (from the standardisation sample). The samples consisted of normal South African (n=129) and British (n=161) children, where normalcy refers to the absence of sensory, physical, or mental handicap. The study was done in an attempt to explore the suitability of using the GMDS-ER in the South African context. More specifically, the following two aims were pursued: 1. To explore and describe the general development of each of four year groups of a sample of British and South African children by utilising the general developmental quotient of the GMDS-ER 2.

- Description: As the divorce rate consistently rises, the occurrence of single parent families are becoming increasingly prevalent. Despite the marked increase in single custodial parents, research on this population (and more importantly, into the positive aspects such as their subjective well-being) has been neglected. Over the past three decades, psychologists have shifted the emphasis of their research from examining demographic and pathogenic factors to a positive psychology framework focusing on personality and resilience. The general aim of this study was to explore and describe the subjective wellbeing, including satisfaction with life and general happiness, of divorced, single custodial parents. In addition, this study aimed to identify potential patterns among the aspects of subjective well-being investigated and aimed to explore the relationships between these patterns. Thirty-five participants were included for participation in this study by means of non-probability, purposive sampling. The research measures included a biographical questionnaire, the Satisfaction with Life Scale (SWLS) and Affectometer-2 Scale (AFM-2). The data were analysed by the researcher and an independent statistician in terms of descriptive statistics and cluster analysis, or according to content analysis. This reflects a triangulation data collection and analysis method. Key findings included the following: The results of the SWLS indicated that the majority of participants reported being slightly dissatisfied with their lives. The results of the AFM-2 indicated that the participants generally had high levels of positive affect, and low levels of negative affect. However, the participants’ overall levels of happiness were still relatively low. A four cluster solution was obtained, with the clusters being significantly different from each other on all input variables. The first cluster experienced high levels of positive affect, low levels of negative affect, and high levels of overall happiness. The second cluster experienced predominantly slight dissatisfaction with their lives, high levels of positive affect, low levels of negative affect, and slightly low levels of overall happiness. The third cluster reported mostly dissatisfaction with their lives, low levels of positive affect, high levels of negative affect, and very low levels of overall happiness. The fourth cluster experienced predominantly slight satisfaction with xi life, slightly high levels of positive affect, neutral levels of negative affect, and low levels of overall happiness. It appeared that clusters containing participants who were satisfied with their jobs, were involved in a personal relationship and who participated in leisure activities, all experienced higher levels of subjective well-being. Overall, this study emphasises the value of and the need for South African research on the subjective wellbeing of divorced, single custodial parents.
