Internal Consistency of the Serbian Translation of the Stanford Social Dimensions Scale and Association to Strengths and Difficulties Questionnaire Scores in Male and Female Individuals on the Autism Spectrum and Non-Autistic Individuals

We aimed to evaluate the internal consistency of Stanford Social Dimensions Scale (SSDS) translated to Serbian and to test it against the Strengths and Difficulties Questionnaire (SDQ). The sample consisted of 200 patients (32% ASD) of the Institute of Mental Health in Belgrade, Serbia (68 females, 132 males, M[subscript age]=9.61, SD[subscript age]=4.06). Internal consistency coefficients were within good/acceptable range for Social Motivation, Affiliation, Recognition and Unusual Approach subscales and below acceptable for Expressive Social Communication subscale. The non-autistic group scored higher on all subscales compared to the ASD group. All SSDS subscales positively correlated with SDQ Prosocial Behaviors scale. The SSDS is a valuable instrument for accessing sociobehavioral phenotype in both individuals on the autism spectrum and non-autistic individuals.
