D.Litt. et Phil. / A problematic aspect of the latter half of the twentieth century in the South African health context, has been the change of the incidence of hypertension amongst black South Africans from being barely. endemic to being a virtual epidemic. This change in hypertension has had several negative components, notably the development of malignant hypertension wherein a markedly accelerated rate of development in hypertension has led to severely high incidences of morbidity and mortality amongst black South Africans notably in urban areas. Many researchers have cited the rapid process of urbaniztion as being the major cause, of this rapid rise in the relative incidence of hypertension amongst black South Africans. Whereas previously, the rapid rise of hypertension in urbanizing black South Africans has been attributed to the social readjustment, associated with urbanization, recent research have suggested that it is not only stressrelated, but also related to a change in basic lifestyle. Basic lifestyle changes have been found to include a change in work ethic from being a rural, cooperative work ethic, to being an urbanized firstworld type A, aggressive, competitive workstyle. This has led also to changes in eating habits with the ingestion of more salt, fats and oils, and has led to a hurried, but non exercised lifestyle. Because of the rapid increase of incidence of hypertension amongst black South Africans, the treatment of this condition has become problematic~ While black South Africans do not respond as well to traditional pharmacological interventions in this condition, they also show side-effects which make it very difficult for them to continue taking this medication. The cost aspects have also been noted to be prohibitively high and the availability of medicines because of the cost aspects has been projected to decline in the coming century. For this reason it would be "important to address other adjunctive measures to treat hypertension amongst black South Africans. In addition to standard harmacological interventions , it appears that there has been mention in the Iiterature of. lifestyle changes to be an efficacious intervention method in stabilizing and reducing blood pressure amongst hypertensives. This has however not been investigated individually or systematically amongst black South Africans. It was therefore the purpose of this study to investigate the effectiveness of lifestyle intervention programs, notably an aerobic exercise intervention, a dietary intervention, and an intervention to increase assertiveness and therefore reduce the aggressiveness associated with the competitive working style acquired by black South Africans. In order to test the efficacy of these treatment measures, a large group of black mineworkers were selected on a basis of meeting the diagnostic criteria for essential hypertension. These black mineworkers were then systematically sUbjected to an aerobic exercise intervention, a dietary intervention, and anger management by means of assertiveness training. Various measures were performed on a pretest and posttest basis. All three interventions were shown to have moderate efficacy. It was found that aerobic exercise, the dietary intervention and the anger management to be associated with a decline in both systolic and diastolic blood pressure, and to be associated with a reduction in the taking of hypertensive medication as ordered by the attending physicians. The aerobic exercise intervention also indicated that black South African mineworkers are relatively unfit and a ch~nge in fitness resulted in a decline in systolic and diastolic blood pressure. The dietary intervention proved to be efficient in terms of changing lifestyle eating habits. Of note is the fact that there was a substantial decrease in the taking of medication when compared to a· control group. It would appear from this research that the specific forms of lifestyle change in black hypertensives noted in this study would be an efficient adjunct or even a substitute for present treatment of hypertension amongst black mineworkers.

M.A. / The effective management of resources is of cardinal importance to ensure the continued existence of an organisation. Within the context of the South African Police Service police officials render a service to their clients on a daily basis, which entails working with people and being in constant contact with people. Their work relates to trauma and problems and involves extensive exposure. As a result of the intense and dynamic nature of the service providers' contact with the community, they expend a lot of energy and suffer emotional exhaustion. Excessive exposure to trauma, a considerable workload regarding dossiers, a poorly functioning judicial system, official red tape in the organisation, frustration at the administrative system and severe staff shortages lead to individual burnout. Burnout in the work environment is a dynamic phenomenon and is assessed as a syndrome. The occupational fatigue syndrome is a distinctly defined reaction which occurs in the human science professions. It is a multidimensional syndrome on account of complex interactions in the work environment. Occupational fatigue is of a progressive nature and manifests itself in various degrees of severity. Police personnel are furthermore subjected to an ongoing process of transformation as a result of political and constitutional changes in the country. Continuous adjustment and constant exposure to trauma and contact with clients lead to exhaustion and decline in productivity.

M.Sc. / The present study describes the experiences of participants on an Adventure Therapy project at the Ekupholeni Mental Health Clinic in Katlehong. It details an account of the violence, both political and everyday, that face South Africans, particularly children and youth. It also attempts to detail the reconstructive challenges facing a democratic South Africa on the road towards healing. The implicit values underlying the research process are the values of Community Psychology and the Action Research method. Themes were drawn from four taped interview (two group and two individual) sessions. These themes suggest that participants have had positive experiences of pride, dignity, control, responsibility and unity through involvement with the project. These experiences are however not without their contradictions. An attempt has also been made to report on this dialectic. The study makes recommendations regarding the improved functioning of this project and also more widely applicable lessons for working with communities. The recreation of community is a struggle better expressed as a process rather than an event. Further documentation of this project is recommended to build on this baseline data.

M.A. / Hubley (1990) notes that Acquired Immunodeficiency Syndrome (AIDS) is a relatively recently recognized disease. It is caused by infection with the Human Immunodeficiency Virus (HIV), which attacks selected cells in the immune system and produces defects in functioning. These defects may not be apparent for years. They lead, however, to a severe suppression of the immune system's ability to resist harmful organisms. This leaves the body open to an invasion by various infections, which are therefore called opportunistic diseases, and to the development of unusual cancers. The virus also tends to reach certain brain cells. This leads to so-called neuropsychiatric abnormalities or psychological disturbances caused by physical damage to nerve cells. Many of those infected with HIV may not even be aware that they carry and can spread the virus. Combating it is a major challenge to biomedical scientists and health-care providers. HIV infection and AIDS occur among the most pressing public policy and public health problems world-wide. Since the first HIV/AIDS cases have been reported in 1981, through mid-1993, more than 600 cases were reported in South Africa. This is only the tip of the iceberg of HIV/AIDS infection as it was estimated that between 2 and 2.5 million South Africans had been infected with the virus through the early 1990s but not yet developed the clinical symptoms. In terms of the historical data from previous surveys (ie. the results of the 1996 survey) in South Africa confirmed the trend of a growing HIV/AIDS epidemic. HIV infection has increased in all provinces, but Kwa-Zulu Natal and Mpumalanga had the highest HIV prevalence rates of 18,23% compared to 1994's '14,35% and 16-18%, compared to 12-16% respectively (see table 1).. Of particular concern are the pregnant women in South Africa under twenty years where a prevalence of 12,78% has been found. Thirty per cent of babies born to HIV positive women in South Africa are infected. Of the 3638 births in VVitbank — a rather small town in Mpumalanga-.Province — in 1996, 219 of the women were tested HIV positive (Masiphile Vol. 1: 1997).

D.Cur. / The purpose of this study was to generate an interpersonal communication skills approach for adolescents. Through this approach adolescents will be given an opportunity to formulate new stories on their interpersonal communication skills in the form of stories about constructive communication skills. This will enable adolescents to maintain their important interpersonal relationships. Adolescence is a period characterised by the occurance of many adjustments and changes. Continually higher demands are made from adolescents in terms of career choices, the choice of friends, release from parents and parental homes, development of autonomy and the successful completion of the adolescent developmental phase. The climate of reconciliation in the post apartheid South Africa pressurise adolescents even more. Sources of support is consequently of great importance to adolescents during this phase of change. Sources of support for example the families of adolescents, members of the community and especially the peer group plays a significant role. interpersonal relationships with the aforementioned groups of persons and individuals must be maintained in order to ensure continued support during and in order to successfully complete the developmental phase of adolesence. This requires constructive interpersonal communication skills. It is however evident that adolescents do not posess all of the required constructive communication skills which would enable them to maintain these important interpersonal relationships. The abovementioned lead to the following questions which were addressed in phase one, -two and -three of this research: Over which interpersonal communication skills do adolescents posess? Which specific interpersonal communication skills needs to be addressed in the interpersonal communication skills approach in order to maximise adolescent's ability to communicate interpersonally with a view to improve, maintain and restore their mental health? Which guidelines can be given for the operationalising of the interpersonal communication skills approach for adolescents? A qualitative, investigative, descriptive and contextual design was followed. The research was conducted in three phases with a pre-phase which preceeded phase one of the research. A topical scenario to be utilised in the course of the research was established in the pre-phase of the research through group interviews with adolescents. In phase one of the research role play was conducted and written dialogue was obtained based on the scenarios identified in the pre-phase. An interpersonal communication skills approach was generated in phase two of the research. In phase three of the research certain guidelines were described for the operationalising of the approach. The researcher concluded from the results obtained in phase one of the research that the interpersonal communication of adolescents included in this research were characterised by an entanglement within four repetative circular interpersonalcommunication patterns. These four repetative circular interpersonal communication patterns are initiated and maintained by certain feelings, thoughts and behaviour. The four repetative circular interpersonal communication patterns are the following: Recurrent circular interpersonal patterns of defocusing and externalizing the topic under discussion; Recurrent circular interpersonal patterns of struggling for power between the adolescent and the other conversationist; Recurrent circular interpersonal patterns of not listening to the other conversationist; and Recurrent circular interpersonal patterns of not focusing on feelings while conversating.

D.Litt. et Phil. / Although PMS has been described almost since the beginning of the written history of medicine, it is still not completely understood. There are many theories about its causation and treatment, and a proliferation of symptoms are ascribed to it. The prevalence of PMS in relation to the total population is still unknown, because premenstrual symptoms or a combination of these range from almost 25% to 100% amongst women. Furthermore, different criteria for the assessment of the prevalence of PMS are used by different researchers. Researchers are in agreement, however, that no single definition for PMS exists. Some women experience mainly psychological symptoms, while others present predominantly physical symptoms. Very little is known of the prognosis of the natural history of PMS. The precise causes of menstrually-related distress is not known, although much has been written about the role that nutrition plays in PMS. A direct relationship has not been identified between individual levels of, and changes in, oestrogen and progesterone alone, and the reported psychological, behavioural and physical changes associated with the cycle. Certain observable behaviours are associated with the premenstrual phase of the cycle, such as aggressive and illness behaviour. An important aspect is the link between premenstrual changes and psychopathology, especially mood disorders. Many researchers report a positive association between premenstrual changes and mood disorders, especially depressive disorders. Women suffering from depressive disorders are reported to frequently experience a premenstrual exacerbation of symptoms and a deterioration in functioning. Most studies have found that women report both psychological and somatic symptoms. The psychological symptoms are, owever, more commonly reported and have also been found to be more distressing for women. In respect of aetiological theories, the literature shows a major subdivision between the biological causes and the psychological basis. Potential causes, according to a biological approach include abnormalities in gonadal steroids, excessive fluid retention, hypoglycemia, abnormalities in prostaglandin metabolism, allergy to endogenous hormones and endogenous opiate withdrawal. Research results in each of these areas are conflicting and conclusions reached are speculative. Most psychological aetiologies originate from the psychoanalytical school and include a rejection or resentment of the feminine role, as well as a repressed wish for a child. At present, the psychoanalytical theories have not been supported by controlled studies and, therefore, still remain speculative. The uncertainty of the causes of PMS is reflected in the numerous treatments proposed in the literature. A review of the literature shows that treatment for PMS is generally given indiscriminately for a divergent group of symptoms, without regard for the fact that growing evidence suggests that the Syndrome is made up of a variety of distinct, but related, symptoms. A girl's first menstruation is a developmental milestone with psychological and physiological concomitants. Adolescents of both sexes tend to view menstruation negatively. Many adolescents associate menstruation with dysmenorrhea. Studies have shown that up to 91% of girls report dysmenorrhea, and it is also the leading cause of recurrent short-term school absenteeism among adolescent girls. Dysmenorrhea cannot be ignored, as it leads to a loss in self-esteem, with all the accompanying problems. If an adolescent does not get help with her PMS symptoms, she may be negatively affected. The purpose of the present study was to cross-culturally investigate the psychological concomitants of the premenstrual symptomatology in adolescent girls. Four hypotheses were tested: In an analysis of symptoms associated with PMS, a single factor reflecting will emerge to account for a significant percentage of the variance observed; Dysmenorrhic adolescents will experience a greater number of negative premenstrual symptoms than non-dysmenorrhic adolescents; Adolescents experiencing a number of negative premenstrual symptoms will report lower self-esteem; Adolescents of different cultural groups will report PMS symptoms that are IV commensurate with their culturally-based health beliefs. In order to test these hypotheses, one hundred and twenty five adolescent girls of all race groups, between 13 and 18 years of age, who were not taking any contraceptive, participated in the study. The Premenstrual Assessment Form (PAF) and the Index of Self-Esteem (ISE) were used. Physical and emotional discomfort emerged as two clear interpretable factors. It would appear that for this sample, PMS is not a unitary phenomenon, but consists of dual factors which are depended on cultural expectations. By observing dysmenorrhic and nondysmenorrhic adolescent girls, it was found that dysmenorrhic girls manifested a significantly higher degree of low mood and loss of pleasure, "endogenous" depressive features, lability, "atypical" depressive features, hysteroid features, hostility and anger, social withdrawal, anxiety, impulsivity, organic mental features, general physical discomfort, water retention, autonomic physical changes, fatigue, impaired social functioning, impaired miscellaneous mood and behaviour changes and miscellaneous physical changes than non-dysmenorrhic girls. Non-dysmenorrhic girls showed a significantly higher degree of well-being when compared with dysmenorrhic girls. Thus, the present study supported the findings of previous research which suggested that dysmenorrhic girls will experience more negative premenstrual symptoms than nondysmenorrhic girls. In respect of self-esteem, girls reporting a number of negative premenstrual symptoms were found to have a lower self-esteem than those reporting fewer negative premenstrual symptoms. In respect of culture, it was found that culture seemed to play a role in the girls' perceived experiences of PMS. The present study indicates that adolescent girls do experience many negative symptoms and, if these are not adequately dealt with, they may adversely affect them in adulthood.

D.Ed. / This inquiry focused on the inclusion of the psycho-biology of learning in teachers activities in school practice. The research question addressed a sample of teachers personal interpretation of the effect of an in-service programme on their practice. The programme consisted of a study of aspects of the biology of learning and how to convert these to instruction. The main claim or thesis of the study was that an inclusive model of education would be incomplete without a psycho-physiological view of learning. After a comprehensive literature review, a field study was launched making use of the following methods: focus group interviews, personal sketches and individual interviews. The data was collated and interpreted per data category and especially as a configuration. Findings from the field study were used to illuminate the thesis or claim that founded the study.

D.Litt. et Phil. / This research focuses on self-concept improvement for adults. A self-image enhancement programme has been developed and its impact tested with regard to shortand medium term developments. Various training approaches have been compared to establish whether massed or spaced sessions training is more effective, and whether individual follow-up after the programme is of advantage. Self-image enhancement is seen as central to a person's functioning and psychological well-being. Self-management and the improvement of the self have taken an important role in today's society where a lot of emphasis is placed on personal achievement and self-actualisation. The background to the research is the question of self-enhancement versus selfconsistency. The self-enhancement thinking promotes the possibility for adult change, while the consistency theories emphasise resistance to change. While an integrated view that places self-image change within the frame of a stable personality becomes necessary, this research aims at establishing the positive changes expected to take place after the self-image enhancement programme. The theories and therapy approaches underlying the design of the self-image enhancement programme include rational-emotive therapy, self-efficacy theory, locus of control theory, and the concept of learned helplessness and learned optimism. The main and subhypotheses were formulated regarding the improvement of the following variables: Total self-concept, physical and personal self, acceptance of others, self-confidence, self-esteem, self-control, nervousness, sociability, formal relations, and self-efficacy. Self-criticism and external locus of control were expected to decrease. The subjects that made up the sample were drawn from companies in Johannesburg and consisted of 133 participants. They were tested before the intervention started, at the end of the course, and again five months later. The self-image enhancement programme was administered to groups of 10 to 12 people. The measurement instruments included the short version of the MMPI, used as the screening device, Vrey's Adolescent Self-Concept Scale, Acceptance of Others Scale, the PHSF Questionnaire, Rotter's Internal-External Locus of Control Scale, and a self efficacy scale. The latter measurement instrument had to be adjusted from another selfefficacy questionnaire and an item analysis was completed. The statistical results show that the self-image enhancement programme is effective in achieving improvement of most of the self-concept variables for all experimental groups taken together. The achieved change was maintained over the medium term except for the self-efficacy and self-control variables. The variables that remained unchanged were acceptance of others, sociability and formal relations, although, based on the literature, an improved self-image is expected to occur with an improved acceptance of others. More research is required regarding interpersonal aspects and self-image enhancement. Regarding the effectiveness of various types of training groups, previous research has not been conclusive. It has also not been established through this study that massed training sessions differ in their effectiveness from spaced sessions, but further research is indicated. The same applies to the role of individual feedback sessions after a training programme. An encouraging finding has been that the self-image enhancement programme is also helping individuals with psychological problems to better their self-image and self- perceptions. This has been shown through the improved results of the MIN PI rejected group and relates to the subhypotheses formulated for this research. This research has confirmed that self-concept improvement during adulthood can be achieved and should in fact be seen as part of ongoing self-development and selfmanagement.

Separate bibliographical references are given at the end of Chapter 7 / The general aim of this research was (1) to develop a holistic and integrated theoretical model for the effective management and evaluation of occupational learning programmes in the South African skills development context, and (2) to develop a valid and reliable measure comprising the elements and dimensions of the theoretical model. The research used a non-experimental cross-sectional survey design. Data were collected from a sample of 652 respondents comprising learning and development managers, learning and development assessors/facilitators/moderators, skills development officers/providers and apprentices/learners. The sample was drawn from organisations representing 5 Sector Education and Training Authorities (SETAs) and the South African Board for People Practices (SABPP). A selfadministered questionnaire was developed for the purposes of this research and its psychometric properties were rigorously scrutinised in accordance with the existing scale development protocols and scientific conventions. Exploratory factor analysis was conducted to establish the factorial structure of the new Learning Programme Management and Evaluation (LPME) scale. The factorial structure was confirmed using confirmatory factor analysis. Further statistical tests conducted include structural equation modelling, multi-group structural equivalence, Pearson product moment correlations, multiple regression analyses and tests for significant mean differences. The findings of this research confirmed an 11 dimensional structure LPME scale. The research confirmed the structural equivalence of the LMPE scale for males and females and type of learning programme. Age, education and occupation were found to be significant predictors of the LMPE sub-scales. This research contributed a valid and reliable LPME scale for the effective management and evaluation of occupational learning programmes in the South African skills development context. To this end, the research provides recommendations for practice and future studies. / Business Management / D. Com. (Industrial and Organisational Psychology)
