The change process questionnaire (CPQ): A psychometric validation

Abstract

Tracking therapeutic processes and outcomes session to session, known as feedback-informed treatment (FIT), has shown many significant benefits for systemic family therapists. However, more clinically useful FIT measures are needed in our field. In response, we conceptualize core dimensions of the therapeutic change process and propose a measure—the Change Process Questionnaire (CPQ)—based on some of those dimensions to provide a clinically useful FIT measure. Developed as a 25-item measure, this study evaluated the measure's psychometric properties, resulting in a refined version with 18 items organized into four subscales (client relationships, client well-being, therapist regard, and therapeutic effect) that demonstrate some alignment with core dimensions of the change process. In this article, we provide a preliminary overview of the CPQ's psychometric validity and potential to contribute to the therapeutic change process and its accompanying scholarly literature.
