This research looked at the effectiveness of motivational interviewing (MI) to treat disordered gambling. MI is a therapy that helps to move a client toward reducing their gambling by confirming and supporting their desire to change. Through a systematic review of existing MI studies and a meta-analysis of their results, this research provides a stronger indication of the effectiveness of MI than is possible with a single study. The researchers examined whether MI led to a change in the number of days gambled per month, and a change in the average dollars lost per month. The researchers also examined the long-term effects of MI on these outcomes.
