title: Motivational subtypes and continuous measures of readiness for change: concurrent and predictive validity.
abstract: This study compared the concurrent and predictive validity of motivational subtypes versus a continuous measure of readiness for change as measured by the University of Rhode Island Change Assessment Scale (URICA; E. A. McConnaughy, J. O. Prochaska, & W. F. Velicer, 1983) in 252 individuals participating in a substance abuse treatment study (38% female; mean age = 36). Hierachical cluster analysis identified a 2-cluster solution. Consistent with previous research, both the motivational subtypes and the continuous readiness measure exhibited good concurrent validity with both baseline characteristics and change process variables. Neither readiness-for-change measure predicted end treatment outcomes. Measures of readiness for change based on the URICA exhibit limited clinical utility, because they are not able to predict future behavior.
