NCT00578357

Brief Summary

The main aim of this randomized controlled trial is to evaluate the sustained efficacy of a personalized feedback intervention for problem gamblers. Adult problem gamblers who express an interest in self-help materials for gamblers will be recruited from respondents to a random digit telephone survey, which also collects the baseline data. Subjects will be randomly assigned to receive personalized feedback about their gambling, or to a waiting list control group. Three-month, six-month, and 12-month follow-up surveys will be conducted by mail to assess gambling over the intervening periods. Collaterals will be requested as part of the 12-month follow-up and interviewed by telephone. Gambling at three- six- and 12-months will be compared between the groups. Change in perception of gambling norms and sex will be tested as mediational and moderating variables.
