Objectives: This study compared problem gamblers, problem substance users, dual-problem individuals, and persons without these problems in the general population.
Methods: On the basis of computer-assisted telephone interviews of a random sample of Texas adults (n = 6308) standard instruments were used to gauge substance use and gambling problems in the general population.
Results: Compared with those having a substance use or gambling problem only, dual-problem individuals were more likely to be young, never-married men, without conventional religious affiliations. There was more dysfunctionality (as evidenced by treatment-seeking and problems with the law) among dual-problem respondents than among those troubled exclusively by gambling or substance use problems.
Conclusions: Screening and treatment for gambling problems should be offered in drug treatment and criminal justice arenas.
