Testing the psychometric properties of the Chinese (Cantonese) version of SATIS-Stroke in people with chronic stroke

Purpose: To culturally adapt and examine the psychometric properties of the Chinese (Cantonese) version of SATIS-Stroke (C-SATIS-Stroke) in people with chronic stroke. Materials and methods: Forward and backward translations were performed in accordance with available guidelines. We administered the C-SATIS-Stroke to 101 people with stroke and 50 healthy older adults. We assessed the test–retest and internal reliability, measurement error, known-group validity, correlations with other outcome measures, optimal cut-off score and ceiling and floor effects. Results: C-SATIS-Stroke demonstrated excellent internal consistency (Cronbach’s α = 0.959) and good test–retest reliability (intraclass correlation coefficient_3,1 = 0.913). Compared with healthy controls, people with chronic stroke had lower C-SATIS-Stroke scores. The mean C-SATIS-Stroke score was significantly correlated with the mean scores of the Activities-specific Balance Confidence Scale, Stroke Impact Scale, Community Integration Measure and Survey of Activities and Fear of Falling in the Elderly. The cut-off score to distinguish the levels of satisfaction with activity and participation between people with chronic stroke and healthy older adults was 80 out of 108 (sensitivity: 77%; specificity: 72%). C-SATIS-Stroke exhibited ceiling effects but not floor effects. Conclusions: C-SATIS-Stroke is a reliable and valid measure for assessing satisfaction with social participation among Chinese people with chronic stroke.IMPLICATIONS FOR REHABILITATION Satisfactory semantic, idiomatic, cultural, and conceptual equivalence of the C-SATIS-Stroke are in line with those of the original English version of the SATIS-Stroke Excellent reliability and validity of the C-SATIS-Stroke are also in line with those of the original English version of the SATIS-Stroke The C-SATIS-Stroke can be used to assess the subjective satisfaction feeling in terms of social participation among Chinese people with chronic stroke.
