Correlates of Motivation to Change in Pathological Gamblers Completing Cognitive-Behavioral Group Therapy

Abstract:

Objectives: The present study analyzes the association between the motivation to change and the cognitive-behavioral group intervention, in terms of dropouts and relapses, in a sample of male pathological gamblers. The specific objectives were as follows: (a) to estimate the pbkp_redictive value of baseline University of Rhode Island Change Assessment scale (URICA) scores (i.e., at the start of the study) as regards the risk of relapse and dropout during treatment and (b) to assess the incremental pbkp_redictive ability of URICA scores, as regards the mean change produced in the clinical status of patients between the start and finish of treatment. Method: The relationship between the URICA and the response to treatment was analyzed by means of a pre-post design applied to a sample of 191 patients who were consecutively receiving cognitive-behavioral group therapy. The statistical analysis included logistic regression models and hierarchical multiple linear regression models. Results: The discriminative ability of the models including the four URICA scores regarding the likelihood of relapse and dropout was acceptable (area under the receiver operating haracteristic curve:. 73 and. 71, respectively). No significant pbkp_redictive ability was found as regards the differences between baseline and posttreatment scores (changes in R2 below 5% in the multiple regression models). Conclusions: The availability of useful measures of motivation to change would enable treatment outcomes to be optimized through the application of specific therapeutic interventions. © 2012 Wiley Periodicals, Inc.
