DSM-IV-defined common mental disorders: Association with HIV testing, HIV-related fears, perceived risk and preventive behaviours among South African adults
Background. There are few reports from South Africa on how common mental disorders may be associated with HIVrelated perceptions and behaviours.Methods. Between 2002 and 2004, 4 351 South African adults were interviewed. Psychiatric diagnoses of depression, anxiety and substance abuse disorders were based on the Diagnostic and Statistical Manual, 4th edition (DSM-IV). HIVrelated fears, perceived risk and behaviour change were measured using multi-item scales. We analysed forms of behaviour change that were appropriate for risk reduction (such as changes in sexual behaviour) separately frombehaviour changes that were inappropriate to prevent HIV (such as care over things touched or avoiding certain social situations).Results. The presence of any DSM-IV-defined disorder during the previous 12 months was associated with previous HIV testing, increased HIV-related fears, and high levels of perceived risk of HIV. There were no associations between depression, anxiety and substance abuse disorders and appropriate forms of behaviour change for HIV riskreduction. However, individuals with an anxiety or a depressive disorder were more likely to report inappropriate forms of behaviour change. For example, individuals with any depressive and/or anxiety disorders were 1.57 and 1.47 times more likely, respectively, to report avoiding certain social situations to prevent HIV/AIDS compared withthose who did not have such disorders (
