Validation and cross-cultural adaptation of an Arabic version of the chronic pain self-efficacy scale.

BACKGROUND

Self-efficacy in pain sufferers includes beliefs about one's capacity to tolerate pain. For usage by Arabic-speaking individuals, the Chronic Pain Self-Efficacy Scale (CPSS), which was initially developed in English, must be translated and modified into the Arabic language.

OBJECTIVE

To assess the CPSS's psychometric qualities for subjects suffering from chronic pain in Arabic.

METHODS

This was a cross-sectional survey that followed Beaton et al.'s guidelines. The CPSS underwent cross-cultural adaptation and Arabic translation in the initial phase. Then, the reliability and validity of the Arabic version of CPSS were examined. A total of 329 patients completed the questionnaire (40.7% males and 59.3% females).

RESULTS

The subscales had good internal consistency, the Cronbach's alpha was 0.870 for subscale 1 (self-efficacy for managing pain), 0.935 for subscale 2 (physical function self-efficacy), and 0.925 for subscale 3 (coping with other symptoms self-efficacy). Test-retest total scores had an acceptable intraclass correlation coefficient (ICC) of 0.743 (95% CI -0.29 to -0.196, p = 0 . 92 ). When performing principal component analysis with varimax rotation [exploratory factor analysis ( EFA )> 0 . 4 ], the test is helpful. Regarding construct validity, the correlation between the total score of Beck depression inventory (BDI) and CPSS subscales and total score have significant moderate negative correlations ( r =- 0 . 479 ; p = 0 . 001 ) except the pain management subscale has significantly weak negative correlations ( r =- 0 . 345 ; p = 0 . 001 ).

CONCLUSION

The Arabic version seems to be a reliable and valid instrument for evaluating a person's self-efficacy in chronic pain among Arabic-speaking individuals making it a good and acceptable instrument.
