The effect of compliance-improving interventions on the cognitive-behavioural treatment of pathological gambling.
This exploratory study investigated the effect of interventions designed to improve compliance and reduce dropout rates during the outpatient treatment of pathological gambling at a University-based gambling treatment clinic. Forty subjects (29 males, 11 females, mean age = 37.6) meeting DSM-IV criteria (APA, 1994) for pathological gambling were randomly assigned to either a cognitive-behavioural treatment or a cognitive-behavioural treatment combined with interventions designed to improve treatment compliance. Compliance was indicated by the completion of all treatment sessions. Outcome measures were DSM-IV criteria assessed by structured clinical interview, South Oaks Gambling Screen scores, and percentage of income gambled. Logistic regression analyses identified pretreatment characteristics predicting compliance and outcome. Compliance-improving interventions significantly reduced dropout rates, resulting in superior outcomes at posttreatment compared to the cognitive behavioural treatment alone. At 9-month follow-up, there was no difference in outcome between treatments, although both produced clinically significant change. Comorbid problem drinking, drug use, and problem gambling duration predicted poor compliance. Poor outcome was predicted by comorbid problem drinking. The clinical implications of these results are discussed in light of the exploratory nature of the study and the need for future research to address compliance, outcome, and comorbidity issues.
