Psychometric properties of the Finnish Pain-Self-Efficacy Questionnaire in musculoskeletal rehabilitees
The study examined the psychometric properties of the Pain Self-Efficacy Questionnaire (PSEQ) and its associations with depressive symptoms and health-related quality of life. Its ability to explain depressive symptoms and health-related quality of life independently of neuroticism was also studied. Participants of the study were 74 rehabilitees at the beginning of their musculoskeletal rehabilitation program. The psychometric structure of the Finnish PSEQ was examined using principal components analysis, its test-retest reliability using Cronbach’s alpha coefficient and the intraclass correlation coefficient and change over time using a t-test. Associations with depressive symptoms and health-related quality of life were examined with correla-tion coefficients. Linear regression analysis was used to study the ability of the PSEQ to explain depressive symptoms and health-related quality of life independently of neuroticism. The Finnish PSEQ seems to have a unidimensional and internally consistent psychometric structure. Its test-retest reliability is good. The PSEQ is associated with current depressive symptoms as expected but does not explain its variance once neuroticism is controlled.
