Abstract: | This study examined the efficacy 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. 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. Outcome measures included number of DSM-IV criteria met, perception of
control/self-efficacy, desire to gamble, and frequency of gambling episodes. Analyses revealed a significant treatment group × time
interaction (η2partial = .39). Specifically, the group treatments resulted in significant improvements in the dependent measures, while the Wait-List
group remained relatively stable. Overall, CBGT-mapping and TSF had no significant differences on any outcome measure at follow-up
assessments. Analysis of post-treatment and 6-month follow-up reveal a significant improvement in gambling outcomes (i.e.,
fewer DSM-IV criteria met, greater self-efficacy, and fewer gambling episodes (η2partial = .35), with treatment gains maintained at 6 months. 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. |
