Objectives: This study aimed to measure motivation for substance use treatment by using the University of Rhode Island Change Assessment (URICA). The composite URICA scores for Readiness To Change (RTC) and Committed Action (CA) were used to investigate their predictive validity regarding whether patients were still in substance use treatment 3 months after entering treatment.
Methods: The sample consisted of 95 patients from substance use disorder treatment facilities in Norway. The patients were interviewed and given a self-administered URICA at pretreatment and 3 months later.
Results and Conclusions: RTC and CA did not predict being in treatment 3 months later, and only minor associations were found with other investigated variables. The results indicate that the predictive validity of URICA for measuring motivation to change in substance use is low and URICA should be used with caution.
