Validity and Reliability of the Hungarian Version of the Pain Self-Efficacy Questionnaire Among Women with Endometriosis and Chronic Pelvic Pain.

BACKGROUND

Our study aimed to perform Hungarian cross-cultural adaptation and assess the reliability and validity of the Pain Self-Efficacy Questionnaire (PSEQ) in women diagnosed with endometriosis and chronic pelvic pain.

METHODS

The current study was conducted in Hungary among women aged 18-50 (34.39 ± 6.68 years). We examined the reliability of the Hungarian version of PSEQ (PSEQ-HU) by applying internal consistency and test-retest evaluations. Confirmatory factor analysis was used to determine the construct validity of the PSEQ-HU, while Spearman's rank correlation coefficient established the convergent validity using the 36-Item Short-Form Health Survey, numeric rating scale (NRS), Pain Catastrophizing Scale, and Perceived Stress Scale. To determine discriminant validity, two groups were created based on NRS (0-4 no or mild pain, 5-10 moderate or strong pain). The results were analyzed using IBM SPSS version 28.0 software with a significance level of ≤0.05.

RESULTS

A total of 262 women participated in this study. The Cronbach's α was 0.97, and the intraclass correlation coefficient (ICC) values showed adequate reliability (ICC = 0.94. 95% confidence interval 0.88-0.97) for the PSEQ-HU. Based on the Spearman's correlation coefficients the convergent validity showed significant results ( = 0.22-0.63; ≤0.001).

CONCLUSION

We concluded that the PSEQ is a reliable and valid measurement among Hungarian women with endometriosis-related pelvic pain.
