Readiness to change in pediatric chronic pain: initial validation of adolescent and parent versions of the Pain Stages of Change Questionnaire.

Despite the clinical importance of readiness to change in predicting treatment outcomes among adults, no studies have examined this construct among pediatric pain patients. Because parents play a key role in adolescent pain management, both adolescent and parent readiness to adopt a self-management approach to pain merit further study. The primary goal of the current study was to validate adolescent and parent-report adaptations of the adult Pain Stages of Change Questionnaire (PSOCQ). Participants included 259 adolescent patients with chronic pain syndromes and their parents presenting to 2 pediatric pain management clinics. Using confirmatory factor analytic techniques, a 4-factor solution was supported for the parent version (PSOCQ-P) that included Precontemplation, Contemplation, Action, and Maintenance factors, whereas the adolescent version (PSOCQ-A) version supported a three-factor model that combines the Action and Maintenance scales. Within both versions, each of the factors was found to be internally consistent. The PSOCQ-A and PSOCQ-P showed evidence of criterion validity through significant correlations with coping strategies and pain catastrophizing. Stability findings at 4 and 8 weeks after a multidisciplinary pain clinic evaluation are reported. Associations between pediatric PSOCQ scores and demographic, pain, and functional domains were explored to inform future research. Further validation of the PSOCQ-A and PSOCQ-P measures with new, separate samples of pediatric pain patients and parents are needed before use in clinical contexts.
