Translation and validation of the Persian version of the Stroke Self-Efficacy Questionnaire in stroke survivors.

Background: The Stroke Self-Efficacy Questionnaire (SSEQ) is a self-report scale that measures stroke survivors' self-efficacy and covers specific domains of functioning after stroke.
Objectives: We aimed to determine the validity and reliability of the Persian version of the SSEQ.
Methods: This descriptive cross-sectional study included 124 stroke patients in the sub-acute phase (between 2 weeks and 3 months of stroke onset). The original SSEQ was translated to Persian and back-translated to English. Demographic, neurologic examination, 'Persian Stroke Self-Efficacy Questionnaire (SSEQ-P)', and 'General Self-Efficacy Scale' (GSE-10) data were collected. The reliability of the questionnaire was evaluated by test-retest assessment among 30 people with stroke at an interval of two weeks. Factor analysis was used to assess the validity of SSEQ-P. Cronbach's alpha assessed internal consistency in all participants. Statistical analysis was performed by SPSS software version 23 and SmartPLS version 3.
Results: In this study, the mean of SSEQ scores was 87.99 ± 37.09. Content Validity Ratio (CVR) and Content Validity Index (CVI) were favorable. Convergent validity of the questionnaire was reported ( r  = 0.669) using GSE. Factor loadings of items in SSEQ ranged from 0.41 to 0.92. Validity indices (AVE = 0.75, SRMR = 0.07) showed that the single-factor model of the present study owns a favorable fit. Test-retest reliability and Cronbach's alpha values of SSEQ in the present study were calculated at 0.80 and 0.97, respectively.
Conclusions: The Persian version of the SSEQ depicted acceptable reliability and validity and can be utilized to evaluate the self-efficacy of patients with stroke.HIGHLIGHTSStroke Self-Efficacy Questionnaire (SSEQ) is a self-report scale that measures stroke survivors' self-efficacy.The Persian version of the SSEQ demonstrated acceptable reliability and validity and can be used in stroke patients.
