STD-related knowledge, beliefs and attitudes of Xhosa-speaking patients attending STD primary health-care clinics in South Africa.

The primary aim of this study was to describe patients at sexually transmitted disease (STD) clinics in Cape Town, South Africa, in terms of gender, education and age differences relative to their STD knowledge and beliefs, their condom use, as well as their attitudes towards condom use and their condom-use behaviour. The information was collected with a view to developing a health education intervention. Structured interviews were conducted with 2978 randomly sampled Xhosa-speaking STD clinic attenders about their knowledge, beliefs and practices regarding STDs and related behaviours. More males (75%) than females (25%) presented for STD treatment. The majority of patients (92%) were younger than 35 years. Female patients were found to be more aware than male patients of the sexual nature of STD transmission, valued personal autonomy in sexual behaviour and expressed a greater need to use condoms. Males perceived STD symptoms to be more serious, had more misconceptions about the cause of STDs and also more negative beliefs and attitudes towards condom use. Only 34.9% of the patients reported using condoms in the last 6 months while only 24.5% reported regular use. Those who reported condom use were more knowledgeable about the sexual transmission of STDs and the effects of STDs on the neonate. They also had fewer misconceptions about the causes of STDs and perceived STD symptoms to be more serious, attached greater value to personal autonomy in sexual behaviour and condom use and had more positive outcome expectancies of refusing sex than those who never used condoms. The data suggest that targeted interventions directed at males will have to address their inadequate knowledge regarding STDs in terms of transmission, causes, consequences, prevention and cure. Their negative beliefs and attitudes towards condoms will need special attention, especially in view of their multiple partner behaviour. Interventions directed at females will need to improve their knowledge regarding STD consequences, causes, recognition of symptoms as well as improve their knowledge of aspects of prevention and cure. All interventions must facilitate personal autonomy in decision making about sexual behaviour and condom use for both men and women, through skills development programmes that promote self-efficacy in the individual and instil a culture of mutual respect of such in the community.

The learning curve: health education in STI clinics in South Africa.

This qualitative study aims to assess health education practice in sexually transmitted infection (STI) clinics in South Africa with a view to develop improved health education programs in such clinics. Health workers' knowledge of and attitudes towards health education practice, their perceived health education skills, the content of health education in STI clinics and the organizational structure as context for health education were investigated. In-depth interviews were conducted with 18 health care workers practicing in the area of STI control. A lack in knowledge and skills required for effective health education practice was reported. The constraints posed by health workers' current knowledge and skills around health education and the organizational structure in terms of the absence of policy and protocols to govern health education, limited time, space and resources, impede on the actual practice of health education. It seems that these obstacles to health education facilitate a biomedical approach to STI management. This approach is further portrayed in the power dynamics between the health workers as well as between health workers and patients. The data suggest that a health education intervention needs to be directed at an individual level namely at health workers and at the organizational level, i.e. the clinic that provides the context for health education. The newly adopted district health system which equally embraces medical care and health promotion augers well for a holistic management of STIs in South Africa. This would ensure the recognition of all categories of health workers' contributions to health education within their own functions, strengths and time limitations.

The socio-cultural contexts of sexually transmitted diseases in South Africa: implications for health education programmes.

Sexually transmitted diseases (STDs) are widespread in South Africa and contribute to the growing HIV epidemic. As an important step in curtailing the spread of STDs, this study explores STD patients' illness representations within its socio-cultural context, particularly gender relationships. In-depth interviews were conducted with Xhosa- and Zulu-speaking patients in clinics in Cape Town, Western Cape (N = 67) and in rural areas of Kabokweni, Mpumalanga (N = 21) The findings suggest that STD patients' illness representations are reflections of their socio-cultural understanding of disease and of culturally defined gender relations. This, in turn, impacts on their general perceptions of the cause of STDs, their perceptions of the risk of contracting STDs, them entering and using formal and traditional medical treatment and on their ideas of prevention. Thus, healthy behaviours need to be facilitated through multiple educational strategies focusing on an improved understanding of the cause of the STD in its context of gender relations, the development of interpersonal and technical skills, as well as focusing on cues for action.

Effectiveness of health education and health promotion: meta-analyses of effect studies and determinants of effectiveness.

Interventions to promote health that have been developed over the last 20 years in the relatively new scientific health education tradition, have often been evaluated for their effectiveness. Meta-analyses of effect studies on various subfields, show that these interventions generally have quite substantial effects (mean effect sizes, ES, of 0.46 for primary prevention and 0.49 for secondary prevention and patient education). A planned and systematic application of social science theory in intervention development is a strong determinant of effectiveness. However, learning principles such as rewards and feedback, that have been shown to increase effectiveness, are often not or not adequately applied. Also, too few interventions focus on possibilities to facilitate the desired behavior (such as reminders, financial stimuli, and skills improvement). The potential effectiveness of interventions in practice may be increased by systematic development of adoption and implementation strategies, including the creation of 'linkage systems' between intervention developers and representatives of the target and user systems.

Values of hypercompetitive and personal development competitive individuals.

The value systems of hypercompetitive and personal development competitive individuals were examined in a sample of university undergraduates. As expected, people higher in hypercompetitiveness and in personal development competitiveness were both more likely to endorse values related to self-contained individualism such as achievement, hedonism, and a striving for an exciting and challenging life, but only hypercompetitives endorsed the value of power and control over others. Moreover, the data indicated that people higher in personal development competitiveness were more prone to endorse values related to ensembled individualism. In particular, they strongly endorsed values associated with social concern, that is, with caring about the well-being of others and with treating them with respect and as equals, whereas hypercompetitives expressed a lack of such concern. Discussion centered on the socialization process and how it can foster the development of different competitive orientations.

A pre-intervention survey to determine understanding of HIV and AIDS in farm worker communities in Zimbabwe.

A cumulative total of 41,298 AIDS cases have been reported in Zimbabwe as of March 1995. Of concern is the growing evidence of high levels of seroprevalence among rural farm workers. A pre-intervention survey was conducted by interview in one district to examine behavioral factors likely to place farm workers in marginalized rural communities at risk for sexually transmitted diseases (STD) and HIV infection. Seven hundred seventy commercial farm workers from 17 randomly selected commercial farm participated in the study. We found that farm worker communities, which are characterized by educationally disadvantaged women when compared with men (p < .001), have had little exposure to AIDS prevention activities. Beliefs that AIDS is brought about by divine or ancestral retribution were upheld by less education women (p < .001). A significant association was found with respect to perceived risk to HIV and low self-efficacy among uneducated women who articulated helplessness and an inability to protect themselves from HIV infection. Among more educated men, we found acknowledgment about multipartnering and that changes in behavior are more likely to develop as a result of changes in normative values (p = .075). Condom use among men, which is probably the most effective barrier against STD infection, was shown to be associated with age (p < .01) and education (p < .01). The study concludes with recommendations for an appropriate intervention.

Stapedius reflex measurements during surgery for cochlear implantation in children.

Electrically evoked stapedius reflex measurements were obtained in 19 children during surgery for cochlear implantation. They all received the Nucleus device. Stapedius reflexes could be elicited in all the children with congenital deafness but not in all the children with an etiology of meningitis. The intraoperative stapedius reflex thresholds were compared with postoperative values obtained after fitting of the speech processor and with the children's long-term behavioral most comfortable levels (C-levels). The intraoperative reflex thresholds were considerably higher than the postoperative reflex thresholds (44 "stimulus level steps" on the average), which could in part be ascribed to the influence of anesthetics used during surgery. It was concluded that, especially in children with an etiology of meningitis, the intraoperative stapedius reflex threshold (even after corrections for the concentration of the volatile anesthetics used) was a weak predictor of the C-level.

Locus of control and adjustment to cancer.

The English form of the Cancer Locus of Control Scale was administered to an heterogeneous sample of 68 cancer patients. A principal components analysis confirmed the three subscales described in the original Dutch form, however, with five items excluded. Correlations with other measures indicated that high internal control over the course of the illness was associated with a tendency to adopt an attitude toward cancer of 'fighting spirit' whereas high internal control over the cause of the illness was associated with an 'anxious preoccupation' about cancer. No specific relationship was found between scale scores and either depression and anxiety or the tendency to be emotionally controlled. It was concluded that the scale provides a valid measure of perceptions of control of cancer patients and is a useful method of assessing these important psychological responses.

Rehabilitation outcomes of long-term survivors treated for head and neck cancer.

BACKGROUND: Little is known about the rehabilitation outcomes of long-term survivors following treatment for head and neck cancer. There are, for example, no studies on physical and psychosocial rehabilitation outcomes of T1 glottic larynx carcinoma, despite the fact that these form the majority of head and neck cancer sites. Thus, this investigation afforded a unique opportunity for examining similarities and differences among T1 glottic larynx patients, laryngectomy patients, and those who had surgery for cancer of the oral cavity and/or oropharynx along a variety of physical and psychosocial dimensions. METHODS: To describe the impact of these three types of head and neck cancer and their treatment on the physical and psychosocial functioning of long-term survivors, a self-report questionnaire was completed by 110 patients treated between 2 and 6 years previously in a major cancer center. RESULTS: Data indicate that a higher percentage of patients treated with laryngectomy or commando procedures still experience severe psychosocial distress between 2 and 6 years after their last treatment than do patients treated with radiotherapy for a T1 carcinoma of the glottic larynx. Psychosocial and physical complaints are still reported by many laryngectomy patients, apparently the result of problems in effective communication with others. Many commando procedure patients experience problems with respect to food intake, and with disfigurement and its consequences. T1 larynx patients mainly experience a considerable number of physical complaints. The greater the time that had elapsed since treatment, the fewer the psychosocial problems associated with head and neck tumors. Open discussion of the illness in the family, social support, and perceptions of adequate information from the specialist are the most important predictors of positive rehabilitation outcomes. CONCLUSIONS: This study indicates that T1 larynx patients report many physical complaints even though several years had elapsed since treatment. Also, laryngectomy patients may need psychosocial guidance for a longer posttreatment period and that health care personnel must involve the partner as much as possible in all communications. Commando procedure patients in particular feel hindered by their disfigurement and its consequences. Future research with respect to validation of the specific head and neck modules is needed.
