Validation of a translated Chinese version of the Participation Strategies Self-Efficacy Scale: a cross-sectional study

Purpose To examine the psychometric properties of a Chinese version of the Participation Strategies Self-Efficacy Scale (PS-SES) among stroke survivors. Methods The PS-SES was translated into Chinese. A cross-sectional descriptive study was conducted with 336 stroke survivors recruited from the neurology departments of five hospitals in China. Reliability, concurrent validity, and construct validity of the scale were determined. Results The Chinese version of the PS-SES (PS-SES-C) showed good internal consistency and test-retest reliability, with a Cronbach's alpha of 0.98 and an intraclass correlation coefficient of 0.79. There was a moderate to strong positive correlation between the PS-SES-C and Chinese version of the General Self-Efficacy Scale (r = 0.59, p < .001), positive correlations between the PS-SES-C and Chinese versions of the Modified Barthel Index (r = 0.59, p < .001), Rivermead Mobility Index (r = 0.70, p < .001), and Reintegration to Normal Living Index (r = 0.70, p < .001), and a negative correlation between the PS-SES-C and National Institutes of Health Stroke Scale (r = -0.63, p < .001). Known-group validity and factorial validity were also supported. Conclusions The PS-SES-C is a reliable and valid instrument for assessing self-efficacy in managing the participation of Chinese stroke survivors.
