Eating disorders, substance use disorders, and impulsiveness among disordered gamblers in a community sample.
Disordered gambling and many eating disorders (EDs) involve recurrent loss of impulse control. We examined rates of specific EDs, ED psychopathology, substance use disorders, and their interrelationships with impulsiveness among community members with disordered gambling. Community-recruited adults with pathological (n = 95) or problem (n = 9) gambling (N = 104; 51% female) completed structured interviews and questionnaires. We observed high rates of substance dependence, lifetime EDs, and current ED psychopathology; 20.8% of women (vs 1.9% of men) had a DSM-IV ED, and 37.8% (vs 3.9%) had an ED according to proposed DSM-5 criteria. Although disordered gambling severity was not associated with ED diagnosis or severity of ED psychopathology, greater disordered gambling severity and an ED diagnosis were both associated with increased impulsiveness. These findings suggest that impulsiveness might constitute a common personality characteristic that underlies disordered gambling and EDs.
