Lifetime mental disorders and suicidal behaviour in South Africa

There is relatively little data on the relationship between lifetime mental disorders and suicidal behaviour in low and middle income countries. This study examines the relationship between lifetime mental disorders; and subsequent suicide ideation; plans; and suicide attempts in South Africa. Method: A national survey of 4185 South African adults was conducted using the World Health Organization Composite International Diagnostic Interview (CIDI) to generate psychiatric diagnoses and suicidal behaviour. Bivariate; multivariate and discrete-time survival analyses were employed to investigate the associations between mental disorders and subsequent suicide ideation; plans; and attempts. Results: Sixty-one percent of people who seriously considered killing themselves at some point in their lifetime reported having a prior DSM-IV disorder. Mental disorders predict the onset of suicidal ideation; but have weaker effects in predicting suicide plans or attempts. After controlling for comorbid mental disorders; PTSD was the strongest predictor of suicidal ideation and attempts. There is a relationship between number of mental disorders and suicidal behaviour; with comorbidity having significantly sub-additive effects. Conclusion: Consistent with data from the developed world; mental disorders are strong predictors of suicidal behaviour; and these associations are more often explained by the prediction of ideation; rather than the prediction of attempts amongst ideators. This suggests some universality of the relevant mechanisms underlying the genesis of suicidal thoughts; and the progression to suicide attempts

Explanatory models of mental disorders and treatment practices among traditional healers in Mpumulanga, South Africa

Objective: In many traditional belief systems in Africa; including South Africa; mental health problems may be attributed to the influence of ancestors or to bewitchment. Traditional healers are viewed as having the expertise to address these causes. However; there is limited information on their explanatory models and consequent treatment practices. The present study examines traditional healers' explanatory models (EMs) and treatment practices for psychotic and non-psychotic mental illnesses. Method: 4 focus group discussions (8 healers in each group) and 18 in-depth interviews were conducted. Four vignettes were presented (schizophrenia; depression; panic and somatization) and traditional healers' views on the nature of the problem; cause; consequence; treatment and patient expectations were elicited. Results: Traditional healers held multiple explanatory models for psychotic and non-psychotic disorders. Psychotic illnesses appear to be the main exemplar of mental illness and were treated with traditional medicine; while nonpsychotic illnesses were not viewed as a mental illness at all. Additionally; traditional healers do not only use herbs and substances solely from ""traditional"" sources but rather have incorporated into their treatment practices modern ingredients that are potentially toxic. Conclusion: Interventions aimed at increasing the mental health literacy of traditional healers are essential. In addition; investigations of the effectiveness of traditional healer treatment for psychiatric disorders should be conducted
