    Impact of common mental disorders during childhood and adolescence on secondary school completion
    (Health and Medical Publishing Group (HMPG), 2009) Myer, Landon; Stein, Dan J.; Jackson, Pamela B.; Herman, Allen A.; Seedat, Soraya; Williams, David R.
    There are few data from South Africa and other low- and middle-income countries on how mental disorders in childhood and adolescence may influence different aspects of socio-economic position, including educational attainment. We examined the association between early-onset disorders and subsequent educational achievement in a nationally representative sample of 4 351 South African adults. After adjusting for participant demographic characteristics and traumatic life events, post-traumatic stress disorder, major depressive disorder and substance-related disorders were each associated with increased odds of failing to complete secondary education (odds ratios and 95% confidence intervals 2.3, 1.0-5.1; 1.7, 1.2-2.5, and 1.7, 1.2-2.5, respectively). These data point to the role that early-life mental disorders may play in educational achievement and subsequent socio-economic position over the life course.

    Life stress and mental disorders in the South African Stress and Health study
    (Health and Medical Publishing Group (HMPG), 2009) Seedat, Soraya; Stein, Dan J.; Jackson, Pamela B.; Heeringa, Steven G.; Williams, David R.; Myer, Landon
    Background. Although stressful life events (SLEs) are associated with psychopathology, the contribution from distal and proximal events and the specificity of their association with common mental disorders require further exploration. We examined the association of recent life events and past adversities to mood, anxiety, substance use and impulse control disorders in South Africa. Methods. Data were analysed from the South African Stress and Health study, a population-based study of mental disorders in a nationally representative sample of 4 351 adults. Psychiatric disorders were assessed with the Composite International Diagnostic Interview (CIDI). This included questions covering early and later SLEs (negative life events, relationship stress, partner violence, social strain and adverse events during childhood) and various socio-demographic variables. Logistic regression models were constructed for 3 957 respondents (2 371 female, 1 586 male) with no missing covariate data, to assess life stress and socio-demographic predictors of 12-month and lifetime disorder. Results. Recent negative life events and relationship problems were significant predictors of any 12-month disorder and any lifetime disorder. Physical partner violence predicted any lifetime disorder. There was evidence of specificity for the prediction of mood versus anxiety disorders, with childhood adversity specifically associated with mood disorders but not anxiety disorders. Single marital status was the strongest socio-demographic predictor of any 12-month and any lifetime disorder. Conclusions. Stressful life events, distal and proximal, contribute significantly and independently to the prediction of major psychiatric disorders among South Africans, underscoring the importance of screening adversities in adults with common mental disorders, and of providing appropriate adjunctive interventions.

    Mental health service use among South Africans for mood, anxiety and substance use disorders
    (Health and Medical Publishing Group (HMPG), 2009) Seedat, Soraya; Williams, David R.; Herman, Anna A.; Moomal, Hashim; Williams, Stacey L.; Jackson, Pamela B.; Myes, Landon; Stein, Dan J.
    Background. Europe and North America have low rates of mental health service use despite high rates of mental disorder. Little is known about mental health service use among South Africans. Design. A nationally representative survey of 4 351 adults. Twelve-month DSM-IV (Diagnostic and Statistical Manual, 4th edition) diagnoses, severity, and service utilisation were determined using the World Health Organization Composite International Diagnostic Interview (CIDI). Twelve-month treatment was categorised by sector and province. South Africans in households and hostel quarters were interviewed between 2002 and 2004 in all nine provinces. Outcome measures. 4 317 respondents 18 years and older were analysed. Bivariate logistic regression models predicted (i) 12-month treatment use of service sectors by gender, and (ii) 12-month treatment use by race by gender. Results. Of respondents with a mental disorder, 25.2% had sought treatment within the previous 12 months; 5.7% had used any formal mental health service. Mental health service use was highest for adults with mood and anxiety disorders, and among those with a mental disorder it varied by province, from 11.4% (Western Cape) to 2.2% (Mpumalanga). More women received treatment, and this was largely attributable to higher rates of treatment in women with mood disorders. Age, income, education and marital status were not significantly associated with mental health service use. Race was associated with the treatment sector accessed in those with a mental disorder. Conclusions. There is a substantial burden of untreated mental disorders in the South African population, across all provinces and even in those with substantial impairment. Greater allocation of resources to mental health services and more community awareness initiatives are needed to address the unmet need.

    Perceived discrimination and mental health disorders : the South African Stress and Health study (SASH)
    (Health and Medical Publishing Group (HMPG), 2009) Moomal, Hashim; Jackson, Pamela B.; Stein, Dan J.; Herman, Allen; Myer, Landon; Seedat, Soraya; Madela-Mntla, Edith; Williams, D. R.
    Objectives. To describe the demographic correlates of perceived discrimination and explore the association between perceived discrimination and psychiatric disorders. Design. A national household survey was conducted between 2002 and 2004 using the World Health Organization Composite International Diagnostic Interview (CIDI) to generate diagnoses of psychiatric disorders. Additional instruments provided data on perceived discrimination and related variables. Setting. A nationally representative sample of adults in South Africa. Subjects. 4 351 individuals aged 18 years and older. Outcomes. 12-month and lifetime mood, anxiety and substance use disorders. Results. In the multivariate analyses, acute and chronic racial discrimination were associated with an elevated risk of any 12-month DSM-IV disorder when adjusted for socio-demographic factors, but this association was no longer statistically significant when adjusted for other sources of social stress. In fully adjusted models, acute racial discrimination was associated with an elevated risk of lifetime substance use disorders. Acute and chronic non-racial discrimination were associated with an elevated risk of 12-month and lifetime rates of any disorder, even after adjustment for other stressors and potentially confounding psychological factors. The association of chronic non-racial discrimination and 12-month and lifetime disorder was evident across mood, anxiety, and substance use disorders in the fully adjusted models. Conclusion. The risk of psychiatric disorders is elevated among persons who report experiences of discrimination. These associations are more robust for chronic than for acute discrimination and for non-racial than for racial discrimination. Perceived discrimination constitutes an important stressor that should be taken into account in the aetiology of psychiatric disorders.

    Perpetration of gross human rights violations in South Africa : association with psychiatric disorders
    (Health and Medical Publishing Group (HMPG), 2009) Stein, Dan J.; Williams, Stacey L.; Jackson, Pamela B.; Seedat, Soraya; Myer, Landon; Herman, Allen; Williams, David R.
    Background. A nationally representative study of psychiatric disorders in South Africa provided an opportunity to study the association between perpetration of human rights violations (HRVs) during apartheid and psychiatric disorder. Prior work has suggested an association between perpetration and post-traumatic stress disorder (PTSD), but this remains controversial. Methods. Subjects reported on their perpetration of human rights violations, purposeful injury, accidental injury and domestic violence. Lifetime and 12-month prevalence of DSM-IV (Diagnostic and Statistical Manual, 4th edition) disorders were assessed with Version 3.0 of the World Health Organization Composite International Diagnostic Interview (CIDI 3.0). Socio-demographic characteristics of these groups were calculated. Odds ratios for the association between the major categories of psychiatric disorders and perpetration were assessed. Results. HRV perpetrators were more likely to be male, black and more educated, while perpetrators of domestic violence (DV) were more likely to be female, older, married, less educated and with lower income. HRV perpetration was associated with lifetime and 12-month anxiety and substance use disorders, particularly PTSD. Purposeful and DV perpetration were associated with lifetime and 12-month history of all categories of disorders, whereas accidental perpetration was associated most strongly with mood disorders. Conclusion. Socio-demographic profiles of perpetrators of HRV and DV in South Africa differ. While the causal relationship between perpetration and psychiatric disorders deserves further study, it is possible that some HRV and DV perpetrators were themselves once victims. The association between accidental perpetration and mood disorder also deserves further attention.
