Translation and Validation of a Chinese Version of the Stroke Self-Efficacy Questionnaire in Community-Dwelling Stroke Survivors.

Background: Self-efficacy is a significant factor influencing stroke survivors' participation in self-care and outcomes. The Stroke Self-Efficacy Questionnaire (SSEQ) is a stroke-specific measure of stroke survivors' self-efficacy in performing daily functional activities and self-management. However, there has been no Chinese version of the questionnaire.

Objective: The current study aims to examine the reliability and validity of a translated Chinese version of SSEQ (SSEQ-C).

Methods: The English version of SSEQ has been translated into Chinese. A descriptive study was conducted. A convenience sample of 135 Chinese stroke survivors (mean age 58.9, SD 9.75) was recruited from three community centers and a stroke support group. Eligible participants completed the SSEQ-C, and the Chinese versions of General Self-Efficacy Scale (GSES), Frenchay Activities Index (FAI), and Stroke-Specific Quality of Life Scale (SSQOL). Thirty of the participants completed the questionnaires at baseline and 4 weeks afterwards.

Results: SSEQ-C had a high internal consistency (Cronbach's α 0.92). Test-retest reliability was satisfactory with the intraclass correlation coefficient of the total scale 0.52. Positive correlations were found between the total scores of SSEQ-C, GSES, FAI, and SSQOL (Spearman's ρ: 0.48-0.68, p < 0.01), suggesting acceptable convergent validity. Principal component analysis suggested a two-factor model, namely "Live with new challenges" and "Activity and exercise engagement" in contrast to the single-factor model for the original questionnaire.

Conclusion: The results suggest SSEQ-C is a reliable and valid tool for measuring Chinese community-dwelling stroke survivors' self-efficacy in managing post-stroke condition. More studies are warranted to confirm the two-factor model of the questionnaire.
