Twelve-step facilitated versus mapping-enhanced cognitive-behavioral therapy for pathological gambling: A controlled study

Abstract

AIM: This study examined the ef?cacy of two group treatments for pathological gambling, a node-link mapping-enhanced cognitive-behavioral group therapy (CBGT-mapping) and twelve-step facilitated (TSF) group treatment. PARTICIPANTS: Forty-nine participants meeting criteria for pathological gambling were recruited from local newspaper advertisements. These participants were randomly assigned to one of three conditions: TSF (n = 11), CBGT-mapping (n = 18), and Wait-List control (n = 9); 11 refused treatment prior to randomization. METHODS: Outcome measures included number of DSM-IV criteria met, perception of control/self-ef?cacy, desire to gamble, and frequency of gambling episodes. RESULTS: Analyses revealed a signi?cant treatment group x time interaction (n^2 (partial) = .39). Speci?cally, the group treatments resulted in signi?cant improvements in the dependent measures, while the Wait-List group remained relatively stable. Overall, CBGT-mapping and TSF had no signi?cant differences on any outcome measure at follow-up assessments. Analysis of post-treatment and 6-month follow-up reveal a signi?cant improvement in gambling outcomes (i.e., fewer DSM-IV criteria met, greater self-ef?cacy, and fewer gambling episodes (n^2(partial) = .35), with treatment gains maintained at 6 months. CONCLUSION: These results are consistent with previous research for group treatment for pathological gambling and provide support for the utility of TSF and a mapping-based CBT therapy as viable intervention for pathological gambling.
