There was no difference on any personality trait between problem gamblers with alcohol problems and problem gamblers without alcohol problems. Gender was found to moderate the relationship between reward drive and problem gambling, with heightened reward drive associated with greater gambling problems for men, but not women. Rash impulsivity was associated with problem gambling for men and women. For example, unlike previous research, there were no differences detected between problem gamblers with or without alcohol use problems on either measure of impulsivity.
Replication of this result with a larger sample is needed. In relation to this limitation, a second limitation pertains to how the problem and non-problem gamblers were recruited.
Since it was found that the majority of the problem gamblers came from gambling treatment centres, unlike the non-problem gamblers who were recruited from ads in newspapers, it is possible that these two samples differed on several characteristics — some of which may have influenced the results. Third, the cause and effect relationship between personality traits and gambling could not be determined through the study; longitudinal research, whereby behaviour and personality are assessed across time, is needed to assess such effects.
However, heightened reward drive was only associated with greater gambling problems for men, not women. Some researchers have argued that based on the relationship between impulsivity and treatment dropout, treatment methods should target impulsivity as a means of enhancing treatment retention. Gender moderated the relationship between comorbidity and RI only. The significant positive relationship found between RI and comorbidity for females only was a novel finding for the current study.
Further research is needed to develop an understanding of the etiology of comorbidity. Merinuk, N. Report bugs here. Please share your general feedback.

Inferences drawn from these data should not be extrapolated to populations that are differentially aged and should be cautiously applied to young adults inhabiting different environments.
The limitations of self-report data are now well-known. In spite of their limitations, self-report data are economical and robust enough that their use is very common. These data were cross-sectional and thus causal inference must remain tentative. In spite of its limitations, this study produced valuable new information that can inform research at the interface of personality and substance use; build upon recent work that has addressed the nature of impulsivity; and drive enhancement of prevention and treatment programs, including those carried out by colleges and universities.
