A number of previous studies have indicated that pathological gambling is often associated with depression. Equally, a number of theoretical models of pathological gambling have included depression as a key variable. Here we report a study of depression in pathological gamblers identified within a random sample of 1,615 adults living in the major cities of Galicia (northwest Spain). Pathological gamblers were identified on DSM–IV diagnostic criteria. Depression was evaluated with the Beck Depression Inventory, subjects being classified ‘depressive’ if they obtained a score of 18 or more. Of 19 pathological gamblers who completed the Beck Depression Inventory, 21% were depressive; by contrast, only 9% of the other subjects were depressive. The Beck scores of pathological gamblers were positively correlated with the severity of their addiction as indicated by the number of DSM–IV-specified symptoms reported.
