Development and Validation of the Social Adjustment Scale for Adolescents with Tourette Syndrome in Taiwan

Purpose: The aim of this study developed the psychometric properties of the social adjustment scale for adolescents with Tourette syndrome (SASATS). Design and methods: A cross-sectional study design was conducted. 346 adolescents with Tourette syndrome(TS) were purposively sampled from pediatric outpatient departments at two hospitals in Taiwan. The scale was developed through a phenomenological study of adolescents with TS and by reviewing the literature. The reliability analysis of the SASATS was performed using the corrected item-total correlations coefficients, Cronbach alpha coefficients, and test-retest correlations. An exploratory factor analysis and confirmatory factor analysis were used to examine the construct validity. Results: The content validity index of 0.89 was obtained, and acceptable model fit was achieved according to the explanatory factor analysis and confirmatory factor analysis. The final scale had 17- items and four factors: relationship between self and TS, academic performance, family relationship, and peer interaction. Acceptable values of 0.81 and 0.87 were obtained for the test-retest and internal consistency reliabilities, respectively. Conclusions: The SASATS is a reliable and valid instrument for evaluating social adjustment status in TS adolescents. (C) 2019 The Authors. Published by Elsevier Inc.
