Cognitive-Motivational Behavior Therapy for Pathological Gamblers
Study Details
Study Description
Brief Summary
In the proposed two-arm randomized controlled trial, 200 patients meeting DSM-IV criteria for PG will be randomized to 12 sessions of Cognitive-Motivational Behavior Therapy (CMBT) or to Cognitive Behavior Therapy (CBT).

Detailed Description
CMBT has been developed by our team over the last five years, and has shown very promising results in a small, NIMH-funded randomized pilot trial (R21 MH 064568). We will assess patients biweekly during the active treatment phase and follow them for 12 months after the end of treatment to obtain data on long-term treatment outcome. We hypothesize that CMBT will show higher efficacy and retention than CBT in the treatment phase, and that gains will be maintained at a higher rate during follow-up.
A second major purpose of the proposed study is to elucidate the presumed mechanisms of change by examining potential mediators (readiness to change, irrational beliefs about gambling, coping skills, therapeutic alliance) and moderators (psychiatric comorbidity with Axis I and II disorders, family history of PG, impulsivity, and baseline motivation to change) of treatment response. A better understanding of how the proposed interventions work will help advance the science and treatment of PG and will be helpful in the future refinement and adaptation of CMBT. Identifying patient subgroups for which the intervention is particularly effective is essential for rational treatment selection. Thus, the immediate goal of the project is to compare CBMT versus CBT for the treatment of PG. A long-term goal of the proposed research is to establish effective treatment procedures that reduce the considerable individual and social costs of PG.

---|---|
Active Comparator: CBT The CBT treatment developed by Ladouceur (Consultant) will serve as control condition (outline of published treatment manual by Ladouceur & Lachance, 2006. This treatment served as a model for the cognitive-behavioral component in CMBT and has received empirical support in two studies from Ladouceur's lab (Sylvain et al., 1997; Ladouceur et al., 2004). It places strong emphasis on cognitive correction of erroneous beliefs about gambling and also focuses on coping skills training and relapse prevention. CBT also lasts 12 weekly sessions. |

Experimental: CMBT We used the NIMH-funded R21 mechanism to develop and test the CMBT intervention (Wulfert et al., 2003, 2005; 2006). Treatment will be implemented in 12 weekly sessions (3 motivational enhancement sessions, 8 sessions of cognitive-behavioral treatment, 1 session of relapse prevention) |

Outcome Measures
Primary Outcome Measures
- patient retention [60 weeks]
Retention will be measured by the number of treatment sessions attended
Secondary Outcome Measures
- gambling behavior [60 weeks]
Our primary measure will be money lost gambling. Secondary measures will include days gambled; scores on the PG-YBOCS, proportion of patients meeting diagnosis of PG and of those having achieved abstinence.
