The authors evaluated gambling behaviors, including Internet gambling, among patients seeking free or reduced-cost dental or health care. Three hundred eighty-nine patients at university health clinics completed a questionnaire that included the South Oaks Gambling Screen (SOGS; H. R. Lesieur & S. Blume, 1987). All respondents had gambled in their lifetimes, with 70% gambling in the past 2 months. On the basis of SOGS scores, 10.6% were problem gamblers, and 15.4% were pathological gamblers. The most common forms of gambling were lottery, slot machines, and scratch tickets. Internet gambling was reported by 8.1% of participants. Compared to non-Internet gamblers, Internet gamblers were more likely to be younger, non-Caucasian, and have higher SOGS scores. This study is among the first to evaluate the prevalence of Internet gambling and suggests that people who gamble on the Internet are likely to have a gambling problem. Results also illuminate the need to screen patients seeking health care services for gambling problems.

These data suggest that about 10 percent of active older adults experience gambling problems, which are associated with poor physical and mental health.

This study investigated gender differences among treatment-seeking pathological gamblers. During treatment intake, 115 pathological gamblers completed the Addiction Severity Index (ASI; A. T. McLellan et al., 1985), including a section on gambling severity, as well as the South Oaks Gambling Screen (H. R. Lesieur & S. B. Blume, 1987). When age and income were controlled, gender differences emerged in ASI gambling, alcohol, and legal scores. Men initiated gambling, began gambling regularly, tried to stop gambling, and first entered gambling treatment at a younger age than women. Women were more likely to be living with someone with a gambling or drinking problem but themselves had fewer alcohol and legal problems. Results suggest that gender differences exist in the initiation of gambling dysfunction and its psychosocial correlates. Understanding these differences may assist in developing treatments that address differential needs of male and female pathological gamblers.

This study evaluated the prevalence and correlates of substance abuse histories in 341 consecutive admissions to gambling treatment programs. After controlling for gender, income, and site, gamblers with substance abuse treatment histories (SATH; 31%) had more severe problems than gamblers with no substance abuse treatment histories (NSATH) on the Gambling, Alcohol, Drug, Psychiatric, and Employment scales of the Addiction Severity Index. The SATH group had more years of gambling problems and gambled more days in the month prior to initiating gambling treatment. The SATH gamblers were also more likely to be receiving treatment for mental health problems and reported greater lifetime psychiatric distress than NSATH gamblers. These data suggest that pathological gamblers with substance abuse treatment histories may present more persistent and severe gambling dysfunction and psychiatric problems than those without such histories.
