Turkish cultural adaptation, validity, and reliability of the stroke activity scale in individuals with Hemiparesis

Abstract

ABSTRACT Aim The aim of this study was to make the Turkish cultural adaptation of the the Stroke Activity Scale (SAS). Method This study was designed as a methodological research. The psychometric properties of the SAS scale were evaluated by validity and reliability analyses. Results The average age of 84 stroke patients (mean ± SD) was 59.52 ± 14.03 years. Kaiser-Meyer-Olkin (0.816) and Bartlett’s Test of Sphericity (χ2 = 288.968, df = 10, p < 0.001) showed that the data set can be factored. A one-factor structure was obtained with Principal Component Analysis (PCA). The factor loads of the items obtained with PCA and Confirmatory Factor Analysis (CFA) were found to be statistically significant. The obtained chi-square statistics (χ2 = 2.227, p = 0.694), normalized chi-square/freedom (χ2/sd) value (0 ≤ 0.557 ≤ 2) and other goodness of fit indices showed good compliance. The positive highly significant correlation (r = 0.846, p < 0.001) between the SAS and Rivermead Mobility Index (RMI) scales confirmed the Concurrent validity. Cronbach’s alpha (0.864) value showed high reliability and Intraclass Correlation Coefficient (ICC) value (0.983, p < 0.001) showed excellent agreement. Conclusions In this study, which was conducted for the Turkish adaptation of the SAS scale, the 5-item and 1-factor structure was evaluated as a valid and reliable scale for evaluating the balance abilities of stroke patients living in Turkey.
