Abstract: Problematic gambling and depression commonly co-exist, with limited research indicating that depression and/or psychological distress appear to reduce with brief interventions for problem gambling. The present study was designed to examine the effect, over 36 months, of a brief problem gambling intervention on depression in a population of people seeking help for gambling issues. One-hundred and thirty-one participants were recruited from adult (18+ years) gambler callers to the New Zealand national gambling helpline. They received a manualised version of the helpline’s brief intervention, and were assessed at baseline, 12 and 36 months. Overall, problem gambling severity reduced from a score of 17 (using the Problem Gambling Severity Index) at baseline to a score of 7.5 at 36 months. The percentage of participants with depression reduced from 74% at baseline to 41% at 36 months. For both problem gambling and depression, the greatest reduction was in the first 12 months. Multiple logistic regression analyses at baseline showed an association between problem gambling and depression. Repeated measures logistic regression indicated that reduced problem gambling severity reduced depression and that there was no independent time effect taking place (i.e. the decreased depression was not due to natural recovery). Thus a single brief telephone intervention for problem gambling substantially reduced the prevalence of depression. This has clinical and public health implications with a benefit being that people with depression and co-existing gambling problems may not necessarily need additional treatment for depression if they receive treatment for their gambling issues. View article details, references and access options
