Gambling Among Adults in Germany: Prevalence, Disorder and Risk Factors

Abstract

Aims: The present study aimed at analyzing prevalence of participation in gambling activities, gambling disorder as well as associated risk factors in the German adult population. Methods: Data came from the 2009 Epidemiological Survey of Substance Abuse (ESA) using a mixed-mode design including questionnaires, telephone and Internet interviews. The cross-sectional random sample consisted of 8,006 subjects aged 18 to 64 years. The response rate was 50.1 %. Results: With a 12-month prevalence of 48.0 %, gambling was a common activity differing by gender (males: 53.9 %, females: 42.0 %). Prevalence of pathological gambling (PG; past 12 months) was estimated at 0.3 % and at 1.1 % for subthreshold pathological gambling (SPG). Various socioeconomic characteristics were related to SPG and/or PG. Male gender and non-German nationality have shown the greatest risk factors for PG. Moreover, gambling frequency and multiple gambling participation were positive associated with SPG and PG. A strong association was found for preference for Internet gambling with SPG and for preference for gaming machines and sports events with PG. Conclusions: The results indicate that SPG was genuinely different from gambling without endorsing any DSM-IV criteria calling for more research on the clinical relevance and classification of this subgroup. Furthermore, findings highlight the need for prevention and intervention measures that target subjects with specific socioeconomic and gambling-related risk factors.
