RESUMEN

INTRODUCTION: Although substance use is commonly associated with mental disorders, limited data on this association are available from low and middle income countries such as South Africa. The aims of the study were i) to determine patterns of substance use in young adults, ii) to identify trends of common psychiatric disorders in relation to use of specific substances, and iii) to determine whether specific psychiatric disorders were associated with use of specific substances in the South African population. METHODS: Data were drawn from the South African Stress and Health (SASH) study, a nationally-representative, cross-sectional survey of South African households that forms part of a World Health Organisation (WHO) World Mental Health (WMH) initiative to standardise information on the global burden of mental illness and its correlates. Data from a subset (n = 1766; aged 18 to 30 years) of the SASH sample of 4351 individuals were analysed. The Composite International Diagnostic Interview Version 3 (CIDI 3.0) was used to elicit basic demographic details and information regarding mental illness and substance use. Multiple regression analyses, adjusted for age and gender, were used to identify associations between mental disorders and substance use. RESULTS: Significant associations were found between substance use and mood and anxiety disorders, with a particularly strong relationship between cannabis use and mental disorder. CONCLUSION: The results are consistent with those from previous studies, and reinforce the argument that comorbid substance use and mental disorders constitute a major public health burden.

RESUMEN

INTRODUCTION: Evidence suggests that comorbid psychopathology can negatively affect treatment outcomes in substance users. In South Africa, limited information exists regarding the prevalence, nature and role of psychiatric comorbidity in substance users. This study examined psychiatric comorbidity and its association with specific substance use, and young adult substance users in treatment for substance use. METHODS: Male and female inpatient substance users (n=95; ages 17-30 years) were sampled consecutively in order of admission from three clinics in Cape Town. An interview schedule was administered to elicit patients' sociodemographic and substance use history details. The computer-assisted Diagnostic Interview Schedule DSM IV (C-DIS IV) was administered to screen patients for current psychiatric disorders. RESULTS: The sample was largely male, Coloured, Muslim and single. Cannabis (51.6%) and crystal methamphetamine (17.9%) were the most common first substances of use. Heroin (53.7%) and crystal methamphetamine (33.7%) were the most common substances for which treatment was sought (primary substances). The most common comorbid psychopathologies were anti-social personality disorder (ASPD 87.4%) and conduct disorder (CD 67.4%). Regression analyses showed a marginally significant association between specific phobia and first use of cannabis, but indicated no statistically significant associations between psychopathology and substance use. CONCLUSION: The results demonstrated a high proportion of previously unidentified comorbid psychopathology in inpatient substance users. Further research is needed to investigate psychiatric comorbidity in inpatient substance users.

RESUMEN

Research has shown a positive relationship between substance use and delinquent-type behaviours among adolescents. The aim of this study is to explore the temporal relationships between these outcomes through secondary data analysis of a longitudinal study of high-school students' risk behaviours. Two regression models were compared and gender, socioeconomic status and repeating a grade were found to be consistent predictors of delinquent-type behaviour. Alcohol (OR: 1.26, CI: 1.02-1.55, p = 0.03) and drug use (OR: 1.10, CI: 1.03-1.16, p = 0.002) in the ordinal regression models were significantly associated with delinquent-type behaviours at Time 2 only. A transition model use was then used to measure delinquent-type behaviours as predicted by the previous time period, and results indicated that gender and delinquency were predictive of delinquency. Smoking also significantly interacted with delinquent-type behaviour to increase future risk of this behaviour. The findings point to the need for intervening early with adolescents who show delinquent-type behaviour.

RESUMEN

OBJECTIVE: To evaluate the effects of a high school peer educator training programme on the sexual behaviour and related psychosocial outcomes of peer educators. METHOD: A total of 728 students from 15 randomly selected public high schools in the Western Cape, South Africa, with a peer education programme and 15 matched comparison schools were recruited, comprising 295 students in the intervention group and 433 students in the comparison arms of the study respectively. Age of sexual debut, use of condom at last sex and psychosocial outcomes such as decision making, goal orientation, critical thinking and self-esteem were measured at baseline and follow-up 18 months later. RESULTS: At follow-up, there were no significant differences in the age of sexual debut, use of condom at last sex, goal orientation, critical thinking and self-esteem scores of the peer educators compared to students in the comparison group. Decision-making scores were significantly higher in the peer educators, compared to students in the comparison group (adjusted difference between means 0.14, 95% CI 0.02 to 0.26). CONCLUSION: Even a highly intensive peer education training programme had limited effects for the peer educators themselves. It is clear that community factors, gendered power relations and poverty need to be addressed to have a lasting impact.

RESUMEN

PURPOSE: Little is known regarding the links between mental disorder and lost income in low- and middle-income countries. The purpose of this study was to investigate the association between mental disorder and lost income in the first nationally representative psychiatric epidemiology survey in South Africa. METHODS: A probability sample of South African adults was administered the World Health Organization Composite International Diagnostic Interview schedule to assess the presence of mental disorders as defined in the Diagnostic and Statistical Manual of Mental Disorders, version IV. RESULTS: The presence of severe depression or anxiety disorders was associated with a significant reduction in earnings in the previous 12 months among both employed and unemployed South African adults (p = 0.0043). In simulations of costs to individuals, the mean estimated lost income associated with severe depression and anxiety disorders was $4,798 per adult per year, after adjustment for age, gender, substance abuse, education, marital status, and household size. Projections of total annual cost to South Africans living with these disorders in lost earnings, extrapolated from the sample, were $3.6 billion. These data indicate either that mental illness has a major economic impact, through the effect of disability and stigma on earnings, or that people in lower income groups are at increased risk of mental illness. The indirect costs of severe depression and anxiety disorders stand in stark contrast with the direct costs of treatment in South Africa, as illustrated by annual government spending on mental health services, amounting to an estimated $59 million for adults. CONCLUSIONS: The findings of this study support the economic argument for investing in mental health care as a means of mitigating indirect costs of mental illness.

RESUMEN

Intimate or dating relationships play an important role in young people's psychosocial development and well-being. Yet, we know relatively little about how teenagers conceptualise and experience them. Research knowledge about young people's intimate relationships is largely gleaned from studies whose primary focus has been on adolescent sexuality and violence. This study explored intimate relationships using qualitative data from 12 focus-group discussions and 25 in-depth individual interviews with Grade 8 (mean age = 14.6 years) and Grade 11 (mean age = 17.2 years) young people recruited from Cape Town schools. Although there is overlap between these findings and previous research, this study delved into the microdynamics of teenagers' relationship practices and conceptualisations. Their discussions provide insight into a nebulous dating landscape that is highly gendered and greatly influenced by peer relations. There was a heterogeneity of experience with relationships and sex. Implications for intervention development are discussed.

RESUMEN

BACKGROUND: Alcohol represents a major public health challenge in South Africa, however little is known about the correlates of alcohol use among rural adolescents. This article examines community influences on adolescents' use of home-brewed alcohol in a rural region of South Africa. METHOD: A total of 1600 high school adolescents between 11 and 16 years of age participated in this study. Seven hundred and forty (46.3%) were female and 795 (49.7%) were male. Data on gender were missing for 65 students (4.0% of the sample). The age range was 11-29 years (mean age 16.4 years; Standard deviation = 2.79). A survey questionnaire on adolescent risk behavior that examined adolescents' use of alcohol and various potential community influences on alcohol use was administered. Factor analysis was used to group community-level variables into factors. Multiple logistic regression techniques were then used to examine associations between these community factors and adolescents' use of home-brewed alcohol. RESULTS: The factor analysis yielded five community-level factors that accounted for almost two-thirds of the variance in home-brewed alcohol use. These factors related to subjective adult norms around substance use in the community, negative opinions about one's neighborhood, perceived levels of adult antisocial behavior in the community, community affirmations of adolescents, and perceived levels of crime and violence in the community (derelict neighborhood). In the logistic regression model, community affirmation was negatively associated with the use of home-brew, whereas higher scores on "derelict neighborhood" and "adult antisocial behavior" were associated with greater odds of drinking home-brew. CONCLUSION: Findings highlight community influences on alcohol use among rural adolescents in South Africa. Feeling affirmed and valued by the broader community appears to protect adolescents against early alcohol use. In contrast, perceptions of high levels of adult anti-social behavior and crime and violence in the community are significant risks for early alcohol initiation. Implications of these findings for the prevention of alcohol use among adolescents in rural communities are discussed.

RESUMEN

OBJECTIVES: Tobacco use has been found to be related to contextual-environmental characteristics. This study focuses on the influence of contextual norms on adolescent smoking behavior with consideration of racial differences. METHODS: Data for this study were derived from the South African Community Epidemiology Network on Drug Use survey. Students (n = 1,277) completed a self-administered questionnaire (available in Afrikaans, Xhosa, and English). School-level aggregate measures were developed from the items: whether they thought smoking was wrong, whether they thought they would be seen as "cool" if they smoked, how many of their closest friends smoked, and whether they had repeated a grade level in school. RESULTS: The results of this analysis revealed that after controlling for demographic characteristics, aggregate measures of importance for ever smoking were whether there were school norms of perceiving that smoking was not wrong, perceiving that smoking was cool, and high prevalence of having friends who smoke. Recent smoking was only predicted by attendance at schools with increased levels of academic failure. Black South Africans were less likely to ever smoke than Coloured or White. CONCLUSIONS: This study highlights the saliency of both compositional (academic failure) and ecological (collective perceptions about smoking) characteristics in predicting ever and recent smoking. Collective perceptions of smoking in a predominantly Black school were largely negative. These findings can be used to target school norms regarding tobacco use in Cape Town.

RESUMEN

Mental health problems in childhood and adolescence pose a major threat to public health. Epidemiological studies in high, middle and low income countries indicate that approximately one in five children and adolescents suffer from a mental disorder. In many instances these persist into adulthood. In South Africa, HIV infection, substance use, and exposure to violence increase vulnerability to mental disorders. Child and adolescent mental health services play a key role in reducing the burden of mental disorders in childhood and later in adulthood. This paper focuses on service needs for children and adolescents in South Africa. It commences with a discussion of the prevalence of child and adolescent psychiatric disorders after which the legal and policy context of child and adolescent psychiatric services is described. A framework for child and adolescent mental health service provision is presented, following which steps for reducing the extent of unmet service need are considered. The paper concludes with a call to scale up child and adolescent mental health services in South Africa, based on the stark realities of unmet need and the constitutional rights of children and adolescents to appropriate mental health care.

RESUMEN

Amongst the psychological theories that have been used to help understand why people have unprotected sex, the Theory of Planned Behaviour (TPB: Ajzen 1991) has earned a prominent position. This article is a critical review of 11 peer-reviewed studies conducted in sub-Saharan Africa during 2001 to 2009, which used the TPB as a model of predicting sexual risk behaviour in young people. All the studies revealed the predictive ability of the TPB in urban, rural, and traditional African settings, with R (2) coefficients ranging between 0.14 and 0.67. With data comparing favourably to those obtained in the international literature, these studies indicate that the TPB can be used to study sexual risk intentions and behaviour in sub-Saharan African youth, and question arguments against the theory's use in non-Western settings.

RESUMEN

BACKGROUND A recent situational analysis suggests that post-apartheid South Africa has made some gains with respect to the decentralization and integration of mental health into primary health care. However, service gaps within and between provinces remain, with rural areas particularly underserved. Aim This study aims to calculate and cost a hypothetical human resource mix required to populate a framework for district adult mental health services. This framework embraces the concept of task shifting, where dedicated low cost mental health workers at the community and clinic levels supplement integrated care. METHOD The expected number and cost of human resources was based on: (a) assumptions of service provision derived from existing services in a sub-district demonstration site and a literature review of evidence-based packages of care in low- and middle-income countries; and (b) assumptions of service needs derived from other studies. RESULTS For a nominal population of 100 000, minimal service coverage estimates of 50% for schizophrenia, bipolar affective disorder, major depressive disorder and 30% for post-traumatic stress disorder and maternal depression would require that the primary health care staffing package include one post for a mental health counsellor or equivalent and 7.2 community mental health worker posts. The cost of these personnel amounts to £28 457 per 100 000 population. This cost can be offset by a reduction in the number of other specialist and non-specialist health personnel required to close service gaps at primary care level. CONCLUSION The adoption of the concept of task shifting can substantially reduce the expected number of health care providers otherwise needed to close mental health service gaps at primary health care level in South Africa at minimal cost and may serve as a model for other middle-income countries.

RESUMEN

BACKGROUND: The Camberwell Assessment of Need (CAN) is a widely used instrument to assess the service needs for people with a severe mental illness. No reliability data are available for its use in South Africa. METHOD: Interrater and test-retest reliability were documented for a sub-sample of 194 patients participating in a needs assessment study among people receiving mental health services. Initially, the CAN was administered by one field worker, while another observed and also made ratings. The participant was then re-interviewed approximately one week after the initial interview. RESULTS: With the exception of 'psychotic symptoms' (κ = -0.4) and 'looking after home' (κ = 0.008), Cohen's κ coefficients for interrater reliability ranged from 0.150 to 0.760 for Section 1 of the CAN. Test-retest reliabilities for Section 1 resulted in moderate to substantial agreement, with Cohen's κ coefficient ranging from 0.25 to 0.81. High correlations were reported for the test-retest reliabilities of the remaining sections of the CAN (r = 0.719-0.845). However, the figures for the interrater reliabilities were lower and more variable (r = -0.082-0.408). CONCLUSION: The results of this study suggest that with additional interviewer training, the CAN is a relatively reliable instrument for assessing the needs of youths with severe mental illness.

RESUMEN

Peer education is popular both with governments and with young people. The purpose of this quasi-experimental study was to evaluate the effectiveness of a government-led peer education program on the self-reported sexual health behavior and related psychosocial outcomes of adolescent students in public high schools in the Western Cape of South Africa. Grade 10 students (n = 3934), at 30 public high schools (15 intervention, 15 comparison) were recruited to the study. In the intervention schools, peer educators were recruited and trained to provide information and support to their fellow students. Sexual health behaviors and related psychosocial outcomes of students were measured at baseline and at follow up 18 months later. Comparisons were made between those in the intervention and comparison group schools. We were unable to detect a significant difference in the age of sexual debut, use of condoms at last sex, goal orientation, decision-making or future orientation for students in the intervention group as compared to students in the comparison group. The findings suggest that the peer education program was not effective in reducing the age of sexual debut or condom use. Issues around the implementation of the program suggested that this was sub-optimal. Governments who advocate widespread use of peer education as an approach need to recognise barriers to implementation and ensure ongoing monitoring and evaluation of effectiveness and cost effectiveness.

RESUMEN

PURPOSE: Although adolescents are at high risk for human immunodeficiency virus (HIV) infection, they have not been, included in HIV vaccine trials. METHODS: In preparation for enrollment in HIV vaccine trials, 100 HIV-negative adolescents aged 14-17 years from Cape Town were recruited into a cohort. HIV, syphilis, pregnancy testing, and sexual risk questionnaires were conducted at varying intervals for a year. RESULTS: The mean age of the participants was 15 years, and 70% of them were female. Recruitment was completed within 3 months. Retention was found to be 82% at 1-year follow-up. The main reasons for dropout were as follows: relocation to other communities, phlebotomy, and visit frequency. In a Cox proportional hazards model, only female gender was significantly associated with retention. No change in reported sexual risk occurred, but the proportion of individuals who were aware of their partner's HIV status was significantly higher (17% at baseline, 83% at 1-year follow-up; p < .001). Five pregnancies were reported during follow-up. CONCLUSIONS: To our knowledge, this is the first prospective adolescent HIV-prevention cohort in Southern Africa. Despite reports of risky sexual behaviors and high pregnancy rates, HIV seroconversions did not occur in the retained cohort. HIV-prevention trials with high-risk adolescents will require rigorous efforts to prevent future pregnancies, and may require risk eligibility criteria. Retention may improve with transport provision, visits with incentives, and efforts to retain males.

RESUMEN

BACKGROUND: Little is known about the treated prevalence and services received by children and adolescents in low- and middle-income countries (LAMICs). The purpose of this study is to describe the characteristics and capacity of mental health services for children and adolescents in 42 LAMICs. METHODS: The World Health Organization Assessment Instrument for Mental Health Systems (WHO-AIMS), a 155-indicator instrument developed to assess key components of mental health service systems, was used to describe mental health services in 13 low, 24 lower-middle, and 5 upper-middle-income countries. Child and adolescent service indicators used in the analysis were drawn from Domains 2 (mental health services), 4 (human resources), and 5 (links with other sectors) of the WHO-AIMS instrument. RESULTS: The median one-year treated prevalence for children and adolescents is 159 per 100,000 population compared to a treated prevalence of 664 per 100,000 for the adult population. Children and adolescents make up 12% of the patient population in mental health outpatient facilities and less than 6% in all other types of mental health facilities. Less than 1% of beds in inpatient facilities are reserved for children and adolescents. Training provided for mental health professionals on child and adolescent mental health is minimal, with less than 1% receiving refresher training. Most countries (76%) organize educational campaigns on child and adolescent mental health. CONCLUSIONS: Mental health services for children and adolescents in low- and middle-income countries are extremely scarce and greatly limit access to appropriate care. Scaling up of services resources will be necessary in order to meet the objectives of the WHO Mental Health Gap Action (mhGAP) program which identifies increased services for the treatment of child mental disorders as a priority.

RESUMEN

This paper has the following aims: (i) to explore the extent to which students who received an intervention involving HIV/AIDS and sexuality perceived that their teacher cared for their health and well-being, (ii) to investigate the characteristics of students who reported to have caring teachers and (iii) to document the association between students' perceptions of care and reported onset of sexual activity. Data were obtained from the second follow-up survey of a prospective study carried out among high school students in South Africa (Cape Town and Mankweng). We analyzed data from 3483 students who met the inclusion criteria. Students from the intervention group perceived greater care from teachers than students in the control group. Female students and students from Cape Town perceived having received more care, and their perception of care was associated with the number of lessons received, how often students expressed their opinions in class and how often teachers talked about HIV/AIDS, condoms and abstinence. Students who perceived that their teacher cared for their health and well-being were less likely to initiate sexual intercourse. This is the first paper to demonstrate the salience of the concept of care in studies of school-based HIV/AIDS prevention programs in sub-Saharan Africa.

RESUMEN

This study was designed to evaluate the efficacy of the HealthWise South Africa HIV and substance abuse prevention program at impacting adolescents' polydrug use and sexual risk behaviors. HealthWise is a school-based intervention designed to promote social-emotional skills, increase knowledge and refusal skills relevant to substance use and sexual behaviors, and encourage healthy free time activities. Four intervention schools in one township near Cape Town, South Africa were matched to five comparison schools (N = 4040). The sample included equal numbers of male and female participants (Mean age = 14.0). Multiple regression was used to assess the impact of HealthWise on the outcomes of interest. Findings suggest that among virgins at baseline (beginning of eighth grade) who had sex by Wave 5 (beginning of 10th grade), HealthWise youth were less likely than comparison youth to engage in two or more risk behaviors at last sex. Additionally, HealthWise was effective at slowing the onset of frequent polydrug use among non-users at baseline and slowing the increase in this outcome among all participants. Program effects were not found for lifetime sexual activity, condomless sex refusal and past-month polydrug use. These findings suggest that HealthWise is a promising approach to HIV and substance abuse prevention.

RESUMEN

BACKGROUND: Approximately half of the countries in the African Region had a mental health policy by 2005, but little is known about quality of mental health policies in Africa and globally. This paper reports the results of an assessment of the mental health policies of Ghana, South Africa, Uganda and Zambia. METHODS: The WHO Mental Health Policy Checklist was used to evaluate the most current mental health policy in each country. Assessments were completed and reviewed by a specially constituted national committee as well as an independent WHO team. Results of each country evaluation were discussed until consensus was reached. RESULTS: All four policies received a high level mandate. Each policy addressed community-based services, the integration of mental health into general health care, promotion of mental health and rehabilitation. Prevention was addressed in the South African and Ugandan policies only. Use of evidence for policy development varied considerably. Consultations were mainly held with the mental health sector. Only the Zambian policy presented a clear vision, while three of four countries spelt out values and principles, the need to establish a coordinating body for mental health, and to protect the human rights of people with mental health problems. None included all the basic elements of a policy, nor specified sources and levels of funding for implementation. Deinstitutionalisation and the provision of essential psychotropic medicines were insufficiently addressed. Advocacy, empowerment of users and families and intersectoral collaboration were inadequately addressed. Only Uganda sufficiently outlined a mental health information system, research and evaluation, while only Ghana comprehensively addressed human resources and training requirements. No country had an accompanying strategic mental health plan to allow the development and implementation of concrete strategies and activities. CONCLUSIONS: Six gaps which could impact on the policies' effect on countries' mental health systems were: lack of internal consistency of structure and content of policies, superficiality of key international concepts, lack of evidence on which to base policy directions, inadequate political support, poor integration of mental health policies within the overall national policy and legislative framework, and lack of financial specificity. Three strategies to address these concerns emerged, namely strengthening capacity of key stakeholders in public (mental) health and policy development, creation of a culture of inclusive and dynamic policy development, and coordinated action to optimize use of available resources.

RESUMEN

INTRODUCTION: Mental health facilities in Uganda remain underutilized, despite efforts to decentralize the services. One of the possible explanations for this is the help-seeking behaviours of people with mental health problems. Unfortunately little is known about the factors that influence the help-seeking behaviours. Delays in seeking proper treatment are known to compromise the outcome of the care. AIM: To examine the help-seeking behaviours of individuals with mental health problems, and the factors that may influence such behaviours in Uganda. METHOD: Sixty-two interviews and six focus groups were conducted with stakeholders drawn from national and district levels. Thematic analysis of the data was conducted using a framework analysis approach. RESULTS: The findings revealed that in some Ugandan communities, help is mostly sought from traditional healers initially, whereas western form of care is usually considered as a last resort. The factors found to influence help-seeking behaviour within the community include: beliefs about the causes of mental illness, the nature of service delivery, accessibility and cost, stigma. CONCLUSION: Increasing the uptake of mental health services requires dedicating more human and financial resources to conventional mental health services. Better understanding of socio-cultural factors that may influence accessibility, engagement and collaboration with traditional healers and conventional practitioners is also urgently required.

RESUMEN

The present study examines the impact of the HealthWise South Africa prevention intervention on condom use self-efficacy. Students from the Cape Town area were assessed at the beginning and end of each school year, beginning in the 8th grade and ending in the 11th. The intervention was delivered in 12 lessons during the 8th grade and 6 lessons during the 9th grade. Using three-level multiphase mixed-effects models, we found that HealthWise had a statistically significant positive effect on condom use self-efficacy, although effects differed for boys and girls. HealthWise had an effect during the first phase of the intervention (8th grade) for girls and during the second phase (9th grade) for boys. We speculate that the gender differences occur because the 8th grade lessons of the intervention taught skills such as discussion, decision making, and negotiation, which may be more salient to girls, and a 9th grade lesson explicitly focused on condom use within the context of sexual relationships, which may have been more salient to boys.
