Personality traits of alcohol and other drug users in Cape Town, South Africa
The Substance Use Risk Profile Scale (SURPS) is a relatively new questionnaire that assesses individual personality risk for substance-related problems. Preliminary findings have indicated that the SURPS is a useful measure for identifying characteristics predisposing some individuals to alcohol and other drug (AOD) use. High levels of hopelessness, anxiety sensitivity, sensation seeking, and impulsivity are each associated with specific patterns of substance use caused by underlying motivational susceptibilities. Furthermore, incorporating these traits into tailored prevention and treatment efforts have shown value in other countries. The present study enrolled a community sample in Cape Town, South Africa and asked respondents about their demographics, history of AOD use, personality as measured by the SURPS, and other mental health indicators. This information was used to identify personality risks in the local population and validate the utility of the SURPS for the first time in Sub-Saharan Africa. Results found that sensation seekers had a significantly higher risk for alcohol, tobacco, cannabis, cocaine, and hallucinogen use compared to other personality groups and controls. As expected, respondents demonstrating anxiety sensitivity also showed high-risk use of alcohol, but less high-risk illicit drug use . Finally, the hopelessness group exhibited a higher risk for opioid use but overall, hopelessness and impulsivity had little impact on concurrent substance use, which contrasts with other literature. Unlike findings from mostly European and North American samples that indicate generalizability, this study did not find structural or concurrent validity for the SURPS. This provides evidence against it being adopted as a culturally appropriate assessment tool in a diverse South African population.
