Abstract

The purpose of this study was to examine the reliability and validity of the Chinese version of the SSIS Autism Spectrum Scale Teacher Form, a scale of the SSIS-Rating Scales (Social Skills Improvement System Rating Scales) created by Gresham and Elliott. The scale consists of 15 items divided into two subscales: social skills and problem behaviors related to autism. The participants included 541 school-age children aged 4 to 18 years old (266 females, 275 males). The Autism Behavior Checklist-Taiwan Version Teacher Form was used as a criterion measure. Data analyses were performed using SPSS 25 and Mplus 8.3 statistical package programs, with procedures including reliability testing, criterion-related validity testing, and confirmatory factor analysis (CFA). The results suggested that the SSIS Autism Spectrum Scale Teacher Form has adequate internal consistency reliability, test-retest reliability, and convergent validity. In addition, the confirmatory factor analysis results supported the two-factor structure of the Chinese version of the SSIS Autism Spectrum Scale Teacher Form.
