The transtheoretical model has been applied to many addictive disorders. In this study, psychometrics properties of the University of Rhode Island Change Assessment (URICA) scale were evaluated in 234 pathological gamblers initiating treatment. Four components were identified--reflective of precontemplation, contemplation, action, and maintenance stages--with internal consistency from .74 to .88. Cluster analyses identified 4 patterns of responding, ranging from ambivalent to active change. The 4 clusters differed with respect to baseline gambling variables and treatment engagement and outcomes assessed 2 months later. A continuous measure of readiness to change was also correlated with gambling severity and predictive of reductions in gambling. This study provides initial support for reliability and validity of the URICA in treatment-seeking gamblers, and it suggests that stage of change may have an impact on outcomes.
