A novel version of Copenhagen Psychosocial Questionnaire-3: Turkish validation study.

PURPOSE: The aim of the study was to adapt the Copenhagen Psychosocial Questionnaire Version-3 (COPSOQ-3) into the Turkish language.

METHODS: This is a methodologic study. The field study occurred in four workplaces (call center, hospital, plastic and metal industries). The Kaiser-Meyer-Olkin (KMO) Measure of Sampling Adequacy and Bartlett's Test of Sphericity were used to assess the suitability of the sample for factor analysis. The principal component analysis and varimax rotation methods were used to identify the factor structure.The internal consistency was assessed using the Cronbach's alpha coefficient.

RESULTS: In total, 1076 respondents' questionnaires were evaluated. Fifty-eight percent of the participants were men and the mean age was 31.1 ± 7.7. Sampling adequacy was considered adequate (KMO =0.929). The factor analysis of the Turkish COPSOQ (COPSOQ-TR) identified 19 factors with eigenvalues higher than one and explained 66.1% of the total variance. The Cronbach's alpha values of 23 dimensions were over 0.70. The Cronbach's alpha values of control over working time and predictability were 0.54 and 0.66, respectively. The model was an excellent fit (Chi-Square = 8514.5, x2 /df = 2.48, RMSEA = 0.038, SRMR = 0.053, CFI = 0.98).

CONCLUSIONS: Findings show that COPSOQ-TR is a reliable and valid instrument that can be a useful tool to measure psychosocial risks in the Turkish language.
