Drinking patterns of pathological gamblers before, during, and after gambling treatment.

Despite the high co-occurrence of alcohol consumption and gambling, few studies have investigated alcohol use changes during gambling treatment. Using latent growth modeling, we examined weekly alcohol use trajectories of treatment-seeking pathological gamblers across 36 weeks, allowing rates of change to differ across the 12-week pretreatment, during-treatment and posttreatment periods. For these secondary data analyses, we retained drinking gamblers (N = 163) from a combined sample of two randomized clinical trials for the treatment of pathological gambling. Results indicated a decrease in alcohol use corresponding with treatment entry and maintenance of less drinking during treatment and posttreatment. Despite these decreases in alcohol use overall, 31% (50 of 163) of participants exhibited risky drinking during the treatment or posttreatment periods. Gender, age, at-risk drinking (at any point in the 36-week interval), baseline gambling severity, treatment condition, and gambling during treatment predicted latent alcohol use growth factors. Although entry into gambling treatment was temporally associated with reductions in alcohol use in this retrospective analysis, a substantial portion of the sample exhibited at-risk drinking after treatment entry, suggesting that interventions targeting reductions in alcohol use may be useful for this population.
