- Description: Due to the complex nature of chorioamnionitis, women are often misdiagnosed, undiagnosed or only diagnosed after birth when it is too late to prevent maternal and neonatal complications. A lack of a comprehensive best practice guidelinefor screening and managing women withchorioamnionitis resultsin delayed treatment and management that could minimise maternal and neonatal complications. Saving Babiesreported that unexplained intra-uterine deathsremained the main primary (obstetric) cause of death for babies with a weight above 1000g (24.4%of all deaths). Of these unexplained uterine deaths, 33% are of normal birth weight (>2500g), and,therefore,most likely term gestation. Saving Babies further reported that 22.9% of all live births in South Africa was premature and 22.8% of birthswere unexplained intra-uterine deaths. Prematurity is one major complication of chorioamnionitis. When susceptibility for chorioamnionitis is considered during early pregnancy, it is possible to intervene and prevent or even reduce the incidences and complications of chorioamnionitis.A qualitative research study was conducted in three phases. In Phase One(Part One), a theoretically constructed patient scenario of chorioamnionitis was presented to ten midwives,and semi-structured individual interviews were done to elicit information regarding how they screen for and manage chorioamnionitis. In Phase One(Part Two), experienced medical practitioners in the field of obstetrics and gynaecology were individually interviewed, also using semi-structured individual interviewsto gain their views regarding chorioamnionitis as a contributing factor to maternal morbidity and mortality. Qualitative findings in Phase Oneindicated that there is a general lack of knowledge regarding chorioamnionitis among midwives, resulting ininadequate screening, misdiagnosis and mismanagement of the condition. Experienced medical practitioners confirmed that chorioamnionitis is underdiagnosed, misdiagnosed or undiagnosed and underreported,and they hold views that it is difficult to treat and control pregnancy-related infections according to current practice.An integrative literature review was conductedin Phase Twoand literature regarding diagnostic biomarkers, screening options to diagnose chorioamnionitis and management of chorioamnionitis were extracted. After evidence synthesisofPhase Oneand Phase Twodata, a best practice guidelinefor screening and managing viiwomen withchorioamnionitiswas developed usingthe National Institute for Health and Clinical Excellence guideline development approach in Phase Three. The purpose of the best practice guideline for screening and managing women with chorioamnionitis was to provide a guideline onhow to manage women who are at risk and those who present with signs and symptoms of chorioamnionitis at any stage during their pregnancy. Five recommendations were made that involve screening for chorioamnionitisand causative factors, biomarkers to diagnose chorioamnionitis, management of chorioamnionitis that includes pharmacological and non-pharmacological management, and health education to women.Ethics for this research study were guided by the ethical principles and guidelines of the Belmont Report. The trustworthiness of this research study was adopted from Ravitch and Carl,and was based on criticality, reflexivity, collaboration, and rigour.

- 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: The first study conducted in South Africa of a prominent figure traces back as far as 1939. Since then, extensive research has been done in the field of psychobiography, resulting in a growing interest in this field and evolving into an established research genre in South Africa. Despite the increase in the use of psychobiographies as a research approach internationally and specifically in South Africa, its use is still considered relatively under-utilised and, therefore, the pursuit of further development of psychobiographies in South Africa is required. In light of South Africa’s effort to promote and advance the use of psychobiographies, South African researchers may be motivated to continue studying significant and exceptional lives in South Africa and abroad. Viktor Frankl was selected for this study based on his uniqueness, significance and his interesting life. He is also considered an exceptional individual who has shaped modern psychological thinking. Frankl had written over 40 books on his theory and many studies have been conducted based on his existential theory. Frankl’s contribution to the academic world has been recognised and acknowledged by significant institutions through his own and others’ research. Although much has been written on the life and work of Frankl, none of the literature utilises specific psychological focus and no psychobiographical study of the life of Frankl exists. Therefore, the researcher selected Frankl as the subject for this psychobiography through purposive sampling. The aim of the study was to provide a psychological exploration and description of Frankl’s life against the backdrop of his socio-cultural context. In order to achieve this aim, the researcher employed two psychological frameworks to guide in the description and exploration of his life. The psychological frameworks included Levinson’s life structure theory of adult development and Frankl’s existential theory. The study aimed to describe Frankl’s development with the use of Levinson’s theory while describing how he attained meaning in his life with the use of his own existential theory. Due to the exploratory-descriptive nature of this study, the objective fell within the inductive research approach. The researcher utilised a systematic coding method to arrange the data. The theoretical framework of Levinson’s life structure theory guided the coding system, as well as the key concepts of Frankl’s existential theory. In addition, the researcher utilised Alexander’s guidelines for the extraction of salient data, together with McAdam’s methods and recommendations for managing the data. Lastly, the researcher followed the 12-step method of conducting a psychobiography, as proposed by Du Plessis. Findings from this study found a correlation between Frankl’s life and the eras and transitional periods as theorised by Levinson’s theory. The findings of this study, therefore, support the use of Levinson’s theory with regards to the time frames and its use in understanding Frankl’s development. Also, the researcher found that Levinson’s theory was useful in understanding Frankl’s personality development within his context throughout his lifespan. With regards to Frankl’s existential theory, the researcher found that the use of the theory was suitable in understanding Frankl’s search for meaning. Frankl’s concepts of freedom of will, will to meaning, meaning of life, existential vacuum, supra-meaning, dimensional ontology, the three triads and noö-dynamics assisted in explaining Frankl’s drive to find meaning in his life, take responsibility to attain such meaning and to strive for transcendence beyond his suffering. The researcher found Frankl’s theory useful in explaining his drive, motives, needs and patterns of behaviour within this context. The holistic and integrative approach of the study allowed for an in-depth exploration and description of Frankl’s life and development within his socio-historical context. In addition to contributing to the existing body of knowledge on Frankl, his life and his theory, the study also contributed to the growing field of psychobiographical research. The study acknowledged and highlighted that further in-depth examination of the lives of extraordinary personalities could significantly contribute to psychobiographical studies. Based on the psychological frameworks used to explore and describe Frankl’s life, recommendations are made for future research.

- Description: The focus of this study is on mothers, motherhood and the Babies in Mind programme as an early intervention strategy for mothers in South Africa. The rate of maternal mental ill health in our country is alarming. Research consistently confirms that maternal mental health directly affects infant and child mental health. One of the major determinants of mental health is mother-infant attachment. Studies have indicated the range of deleterious effects that maternal mental ill-health and mother-infant attachment issues have on offspring from infancy to adulthood. This has implications for the mental health of future generations and society at large. Researchers have called for evidence-based interventions that address maternal mental health and mother-infant attachment, especially in developing countries. South Africa has no national prevention or treatment programme to address these needs. This study investigated the Babies in Mind programme as an early intervention option to address the gap in promoting maternal mental health and mother-infant attachment. A social constructionist, narrative study was employed to meet the objectives of the study. The aim was to explore mothers’ perceptions of the impact of the Babies in Mind programme, with particular reference to their mental health and their relationships to their infants. Focus was placed on understanding the social constructions of motherhood at the community level and how these constructions were reconstructed through the programme. Purposive sampling was employed and focus groups were conducted to collect the relevant data. The data was analysed using thematic analysis. The findings indicated that mothers’ experiences of the Babies in Mind programme were positive and there were improvements in their mental health and relationships to their infants. A relationship model for mothers was developed based on the themes that emerged from the data analysis. A platform for continued support and discussion was organised via a social media (Whatsapp) support group. Twelve 7guidelines were suggested for the implementation of intervention programmes such as the Babies in Mind programme at the community level.

- Description: Traumatic Stress Disorder (PTSD). While the literature provides detailed and comprehensive approaches and counselling modalities to working with clients who experience traumatic events, there is not much evidence on the experiences of individuals who reside in high crime communities. It follows, that the psychological and emotional experiences, as well as needs of such individuals may present with specific requirements from the therapeutic alliance. This study aimed to explore the psychological and emotional effects of repeated exposure to high crime and violence and the implications this posed to traumatic experiences. The study further aimed to develop a set of guidelines that can be drawn upon when working therapeutically with clients who reside in high crime communities. The study draws on a qualitative methodology and 17 participants were interviewed. The transcripts were analysed using thematic analysis and five themes were identified, relevant to the aims and objectives that were set. The findings suggest that the psychological and emotional experiences of individuals who reside in high crime communities, is experienced at a more heightened and prolonged period, thus making the psychotherapeutic intervention employed, more specific. To this effect, the guidelines developed provide specific strategies and approaches thatwere developed based on the themes identified and verified by a panel of psychological experts. The study contributes to the field of trauma, counselling and violence, in that it focuses on an area of trauma that has not been adequately focused on withinthe South African context, as well as in global contexts.

- 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: Best practice guidelines (BPGs) are the use of scientific evidence to direct patient care and guide clinical care to integrate best patient outcomes. The implementation of BPGs in operating theatre nursing improves patient safety and quality of care and enhances patient outcomes. Although BPGs are crucial, the implementation thereof is not well operationalised in clinical practice, especially in an area such as the operating theatres in public hospitals in the Nelson Mandela Bay Health District(NMHD)in the Eastern Cape Province. The study thus developed strategies that could be used to facilitate the implementation of best practice guidelines in the operating theatres at public hospitals in the NMBHD. Understanding registered nurses’ knowledge, attitudes, and practices (KAP) with regard to implementing BPGs in the operating theatre is important, as it will assist in the development of strategies to facilitate the implementation of BPGs.The study was conducted in three phases. Phase One comprised of a quantitative approach. Data collection was achieved by means of a self-administered questionnaire which was distributed to registered nurses in the operating theatres of public hospitals in the NMBHD. The purpose of the questionnaire was to establish their knowledge, attitude and practice with regard to best practice guidelines and the implementation thereof. Recommendations made by participants for strategies to facilitate the implementation of BPGs in operating theatres were also explored. Descriptive and inferential statistics were utilised to analyse and describe the data. Descriptive statistics were used to describe the profile of the sample, including the demographic data measures of central tendency, for example the mean and standard deviation (SD) and correlation techniques.Chi²analysis was performed to test for significance of the associations between the registered nurses’ demographic variables and their KAP. Data were categorised into three levels, namely lower (score < quartile 1 i.e. bottom 25%). Middle (quartile1 ≤ score ≤quartile i.e. in the middle 50%) and higher (score > quartile 3 i.e. top 25%).Findings from this research study revealed the limited knowledge, attitude and practice of OT nurses about BPGs. During Phase Two an integrative literature review approach was followed in order to identify the best available evidence with regard to the facilitation of the implementation of best practice guidelines in operating theatres. Lastly, Phase Three: strategies that could be used to facilitate the implementation of best practice guidelines in operating theatres were developed. The researcher developed the conceptual framework using the six elements of Dickoff, James and Weidenbach (1968:422). The conceptual framework informed the development of strategies. The strategies are a synthesis of the conclusions drawn from the research findings (phase one and two) and the conceptualization thereof. The strategies were reviewed by six-panel members. Each panel member was supplied with the format for evaluation of the strategies which was based on the criteria established by Chinn and Kramer (2018:156) the results of which included in chapter 7. The researcher ensured that the data obtained was valid and reliable, necessary to assist the researcher to produce quality research. Ethical considerations were maintained throughout. In general, the results of this thesis indicate that the developed strategies that could be used to facilitate the implementation of best practice guidelines, in operating theatres at public hospitals in the NMBHDare unique and could be implemented in theatres in public hospitals. The researcher succeeded in achieving the purpose for this study, because the strategies which are understandable, clear, simple, applicable and significant to operating theatre unit has been developed for use by operating theatre nurses, to facilitate the implementation of best practice guidelines in operating theatres at public hospitals in the NMBHD.

- Description: Best practice guidelines (BPGs) are the use of scientific evidence to direct patient care and guide clinical care to integrate best patient outcomes. The implementation of BPGs in operating theatre nursing improves patient safety and quality of care and enhances patient outcomes. Although BPGs are crucial, the implementation thereof is not well operationalised in clinical practice, especially in an area such as the operating theatres in public hospitals in the Nelson Mandela Bay Health District(NMHD)in the Eastern Cape Province. The study thus developed strategies that could be used to facilitate the implementation of best practice guidelines in the operating theatres at public hospitals in the NMBHD. Understanding registered nurses’ knowledge, attitudes, and practices (KAP) with regard to implementing BPGs in the operating theatre is important, as it will assist in the development of strategies to facilitate the implementation of BPGs.The study was conducted in three phases. Phase One comprised of a quantitative approach. Data collection was achieved by means of a self-administered questionnaire which was distributed to registered nurses in the operating theatres of public hospitals in the NMBHD. The purpose of the questionnaire was to establish their knowledge, attitude and practice with regard to best practice guidelines and the implementation thereof. Recommendations made by participants for strategies to facilitate the implementation of BPGs in operating theatres were also explored. Descriptive and inferential statistics were utilised to analyse and describe the data. Descriptive statistics were used to describe the profile of the sample, including the demographic data measures of central tendency, for example the mean and standard deviation (SD) and correlation techniques.Chi²analysis was performed to test for significance of the associations between the registered nurses’ demographic variables and their KAP. Data were categorised into three levels, namely lower (score < quartile 1 i.e. bottom 25%).

- Description: The psychological testindustry has produced a wide variety of psychological tests that are used by professionals to facilitate measurement and decision-making. Tests are updated and revised periodically in order to remain current, valid and reliable in what is a competitive psychometric industry. Despite the prevalence of test revisions, especially in recent years, a number of authors have commented on the lack of comprehensive guidelines for test revision. Guidelines shouldcover aspects such as what the different types of revision are, when to embark on a revision, whatprocessto followand how test users should use revised tests. Test revision differs from test construction in a number of ways. There are external factors that affect the regularity with which a test should be revised. Test revision also involves more role players than test construction, including the opinions of those test users who may be resistant to any change in the previous test edition. Finally, revised tests sometimes have to contend with requirements from the test publisher who purchased the test or distribution rights from the developer. Test revision is expensive and time consuming, which leaves little scope for experimentation or trial-and-error. The availability of expertise, as well as the human and financial resources required to complete test revisionscan make such projects unaffordable, especiallyforprofessionals indeveloping countries, such as South Africa.It may be more feasible for such professionalsto collaborate with international revision projects. By doing so they cangain experience in test revision, contribute indigenous information that could shapethe revision ofan international test, increase opportunities to engage with international users, and potentially source international funding for research in their own country. The current studydevelopeda comprehensive and practical set of 30 guidelines to assist those involved in test revision. These guidelines were peer-reviewed and refined. Finally, the guidelines were field-tested using a case study of a recently revised ivdevelopmentaltest, the Griffiths III. Professionals from South Africa, including the present researcher,formed part of the international team for the extensive revision of the Griffiths III, which makes this test an ideal case study from both the perspectives of the developed test revision guidelines as well as collaboration of professionals from a developing country in an international test revision. The knowledge gainedfrom the development of guidelines and international collaboration in test revision is reflected on.
