Summary
Brief summary
The purpose of the study is to investigate the effectiveness of a 5-minute intervention DVD on (1) increased compliance with self-exclusion orders, (2) increased uptake of concurrent mental health treatments, self-help resources and groups, and counseling, and (3) reduction in gambling related-harms and severity of problem gambling. The design will include a randomized controlled trial (an intervention group (DVD) and a control group receiving current standard procedures) in which the DVD will be provided to a sample of self-excluders and outcomes compared to a sample receiving ‘treatment as usual’ that is, the standard self-exclusion information package and procedure.

Specific hypotheses:
1. That a 5-minute intervention DVD informing self-excluders of the nature and requirements of the program and utilizing motivational interviewing principles guiding self-evaluation and appraisal coupled with benefits of accessing complementary treatment interventions will:
a. Increase the proportion of self-excluders taking up referrals to appropriate mental health treatment interventions
b. Increase compliance with self-exclusion requirements as assessed by reduced number of detected and self-reported breaches
c. Reduced severity of gambling behaviour and harms as assessed by scores on the PGSI of the CPGI, DSM-IV, patterns of self-reported behaviour and expenditure, improved relationships and psychological well being, and measures of gambling-related harms, in addition to event history (timing of breaches relative to initiating self-exclusion).
