Validation of the Farsi version of the Pain Management Self-Efficacy Questionnaire (F-PMSEQ)

Introduction: Pain management is a complex process that is managed through a multi-disciplinary team in which nurses have a significant role. The present study aimed at translating and examining the psychometric properties of the Pain Management Self-Efficacy Questionnaire (PMSEQ) among Iranian nurses. Methods: This was a cross-sectional, methodological study conducted in 2019 among nurses working in two teaching hospitals in Sanandaj (Tohid and Kosar). The participants were selected using a convenience sampling method. Responsiveness; interpretability; and face, content, and construct validities were examined using exploratory and confirmatory factor analyses. In addition, internal consistency and stability were examined using the Cronbach’s alpha, test-retest, respectively. Results: Overall, 410 nurses (210 for the EFA and 200 for the CFA) were included in the sample. In the exploratory factor analysis, two factors of Comprehensive pain assessment and Pain management with eigenvalues of 6.36 and 1.91, respectively, were extracted. The two factors together explained 56.64% of the variance of nurses’ pain management self-efficacy. The confirmatory factor analysis indicated that the model had a moderate fit to the data ((RMSEA: 0.12; NFI: 0.84; NNFI: 0.86; CFI: 0.88; IFI: 0.88; RFI: 0.81; GFI: 0.76; AGFI: 0.69; PGFI: 0.59; RMR: 0.09; Standardized RMR: 0.09). Total questionnaire and the two factors (i.e. Comprehensive pain assessment and Pain management) had internal consistency coefficients of 0.891, 0.876, and 0.803, respectively. Conclusion: The Farsi version of PMSEQ had good internal consistency and reliability, as well as content and construct validity, and can be used in future studies.
