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

BackgroundThe Stroke Self-Efficacy Questionnaire (SSEQ) is a self-report scale that measures stroke survivors' self-efficacy and covers specific domains of functioning after stroke.ObjectivesWe aimed to determine the validity and reliability of the Persian version of the SSEQ.MethodsThis 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.ResultsIn 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.ConclusionsThe 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.
