| Popis: | The purpose of this research was to determaine the psychometric properties of Gilliam Autism Rating Scale (GARS) among Autistic Children and Adolescents in Isfahan. The Statistical population of the study was all Autistic Children and Adolescents (3-18 years), out of which 100 were selected randomly as the statistical sample. Data were collected by administering GARS. Content and face validity of the scale were confirmed by psychology experts. For estimating concurrent validity the correlation between GARS and CARS was 0.80. Its reliability was 0.89 through Chronbach's alpha. The sample was compared with normal children through discriminant analysis. The cut-off point was 52, sensitivity was 99 and specificity was 100 percent. Findings showed that GARS is a valid scale for measuring autism.With regard to its proper validity and reliability, this scale can be used in psychotherapy and research centers. Also, results showed that there was no significant correlation between age and autism symptoms and there was no significant difference between boys and girls in autism symptoms. |
