The Psychological Well-Being Post-Traumatic Changes Questionnaire (PWB-PTCQ) is an 18 item self-report measure to assess perceived changes in psychological well-being following traumatic events. The aim was to test its psychometric properties. Across three samples, evidence is provided for a single factor structure (invariant across clinical and general populations), high internal consistency (α >.87), six month stability, incremental validity over and above existing measures of posttraumatic growth as a predictor of subjective well-being, convergent validity with existing measures of posttraumatic growth (r =.50-.56. p <.001), concurrent validity with personality and coping measures, predictive validity of change in well-being over time, discriminant validity with social desirability, and prediction of clinical caseness.
