Effectiveness of nurse-practitioner-delivered brief motivational intervention for young adult alcohol and drug use in primary care in South Africa: a randomized clinical trial

To assess the effectiveness of brief motivational intervention for alcohol and drug use in young adult primary care patients in a low-income population and country. A randomized controlled trial in a public-sector clinic in Delft, a township in the Western Cape, South Africa recruited 403 patients who were randomized to either single-session, nurse practitioner-delivered Brief Motivational Intervention plus referral list or usual care plus referral list, and followed up at 3 months. Although rates of at-risk alcohol use and drug use did not differ by treatment arm at follow-up, patients assigned to the Brief Motivational Intervention had significantly reduced scores on ASSIST (Alcohol, Smoking and Substance Involvement Screening Test) for alcohol-the most prevalent substance. Brief Motivational Intervention may be effective at reducing at-risk alcohol use in the short term among low-income young adult primary care patients; additional research is needed to examine long-term outcomes.
