NCT02613754

Brief Summary

The aim of this study is to conduct a trial to investigate the efficacy of adding Contingency Management (CM) to Treatment as Usual (TAU) for the treatment of Disordered Gambling. Results from this experiment will provide the first evidence of the additional efficacy of best-practice CM and whether it can be easily integrated into a clinical environment. Additionally, this study will correlate clinical outcomes with psychological measures and participant responses to develop new predictive treatment outcome measures.

Study Arms (2)

Contingency Management

EXPERIMENTAL

Contingency Management (CM+): This procedure is designed to reinforce treatment attendance, non-gambling behaviour, and study completion. Participants will earn points that will be recorded on vouchers that could be subsequently redeemed for gift cards at a variety of local businesses. Submission of evidence of gambling behaviour or non-attendance re-sets the point value for future vouchers to the starting level. This intervention is in addition to Treatment as Usual.

Behavioral: Contingency ManagementBehavioral: Treatment as Usual

Treatment as Usual

ACTIVE COMPARATOR

Treatment as Usual (TAU): This is typically a semi-structured approach for delivering cognitive behavioural therapy addressing the participant's experiences, thoughts, and emotions relating to their gambling.
