This presentation will discuss gambling-related illegal behaviors (GRIB) in the context of presentation, course, and treatment outcomes of pathological gambling (PG) disorder. Among individuals with PG, differences have been found between those who engage in GRIB and those who do not. Recent studies in this area will be briefly reviewed. Original data collected through the Gambling Treatment Program at Louis Stokes Cleveland VA Medical Center in Brecksville, OH will also be presented. This research extends existing literature and evaluates differences between GRIB and non-GRIB groups during the course of residential pathological gambling treatment. This data includes measures of quality of life and gambling-related cognitions as indicators of treatment outcome. In addition, group differences on variables related to demographics, onset of pathological gambling, financial difficulties, type of illegal behavior, and aftercare attendance will be presented. The research in timely, considering proposed changes in the PG diagnostic criteria.
