The psychometric properties of the Finnish Young Schema Questionnaire in chronic pain patients and a non-clinical sample.
We investigated the latent factor structure of the Finnish Young Schema Questionnaire (YSQ-S2-extended; short form) in samples of chronic pain patients (n=271) and controls (n=331) with confirmatory factor analysis (CFA). The data in the total sample supported the 18-factor structure as hypothesized by Young, J. E., Klosko, J., & Weishaar, M. E. (2003). Schema therapy: A practitioner's guide. New York: Guilford Press. The diagonally weighted least squares estimation method gave repeatable parameter estimates in successive confirmatory factor analyses (CFA). The internal consistency of the YSQ-S2-extended was adequate to high in both samples and the groups showed equal goodness-of-fit statistics in CFA. This study consisted of the oldest population so far (mean age 47 years) and supported the use of the Finnish version of the YSQ-S2-extended in clinical practice.
