This assessment utilizes the Riggio Social Skills Inventory to objectively evaluate participants' social interaction skills. The total score ranges from 10 to 40, where higher scores indicate better social interaction skills. The inventory consists of 10 items, each scored on a scale from 1 (Never) to 4 (Always). Scores for each item are summed to compute a total score, with higher total scores representing better outcomes in social interaction skills. The inventory includes subscales that measure aspects of verbal and non-verbal communication.

Time frame: 3 weeks post-intervention

Social Skills Rating System - Parent Version (SSRS-P)

A 3-point Likert scale (1 = Never, 2 = Sometimes, 3 = Often) is used for scoring. The total score ranges from 31 to 93, where higher scores indicate better social skills. Scores for each subscale are summed, contributing to the total score. The SSRS-P is a validated instrument commonly adopted in clinical trials of psychiatric and neurological disorders.
