RESUMO
BACKGROUND: Self-efficacy has been shown to play an important role in rehabilitation outcomes of stroke patients. The Stroke Self-Efficacy Questionnaire Brazil (SSEQ-B) is designed to assess self-efficacy of functional performance after stroke. OBJECTIVE: This research sought to address the structural validity of the SSEQ-B using exploratory and confirmatory factorial analyses. METHODS: This is a cross-sectional study. We performed a reliability assessment and structural validation of the SSEQ-B in 115 Brazilian stroke survivors living in Rio Grande do Sul or São Paulo. Results: Sample mean age was 62.7 ± 14.2 years. Internal consistency presents a Cronbach's Alpha (αC) of 0.829. Exploratory factorial analysis using the scree plot method revealed a bifactorial structure, consisting of activity and self-management domains. While confirmatory factorial analysis suggested a trifactorial structure, the loading ranges between factors 1 and 3 were very similar, suggesting they could be collapsed - resulting in the same factors found in the scree plot analysis. Both structures with subscales showed good construct validity. CONCLUSION: SSEQ-B is a valid and reliable measure of stroke self-efficacy. The preferred structure of the SSEQ-B is bifactorial and includes the domains activity and self-management.
