Stages of change in anxiety: psychometric properties of the University of Rhode Island Change Assessment (URICA) scale.

Readiness for change is increasingly cited as an important variable in the health behaviours literature, yet there remains a dearth of research related to this construct in mental health. This study examined the psychometric properties of the University of Rhode Island Change Assessment (URICA) scale in two samples. In Study 1 (n = 252), undergraduates completed the URICA and were administered measures of hopelessness, the consequences of worry, self-esteem, anxious symptomatology, and social desirability. The reliability and validity of the URICA were generally supported, although the goodness-of-fit with the intended subscales was only moderate. The Precontemplation, Contemplation and Maintenance subscales correlated as expected with ancillary measures, but the Action subscale did not. In Study 2 (n = 81), individuals with panic disorder were administered the URICA at initial assessment and following cognitive behavioural therapy. The URICA demonstrated excellent reliability, significantly predicted treatment retention and dropout, and showed modest utility for predicting treatment outcome. Confirmatory factor analysis, however, revealed an inadequate fit to the intended subscales. The implications of these findings are discussed and directions for future research highlighted.
