Families, teachers, and clinicians use SUPER digital platform in addition to usual rehabilitative and educative interventions.

Families, teachers, and clinicians perform usual rehabilitative and educative interventions.

SUPER digital platform was implemented to ensure synergy between ASD families, health services, and schools through different tools to share rehabilitative and educational objectives and strategies. It was designed following the ASD International Guidelines and the recommendations of the ICF-CY and was organized into two areas: General (to promote scientific knowledge on ASD) and Personalized (restricted virtual space for groups of users following an individual with ASD).

Questionnaire created ad hoc for taking charge: it is a parent-report instrument with 22 items based on a 5-points Likert Scale. Higher scores (maximum 110) mean a better perception of taking charge, while lower scores (minimum 22) mean a worse perception about taking charge.

SUPER Questionnaire is an instrument created ad hoc to evaluate the acceptability of SUPER platform for parents, clinicians and teachers of children with ASD. It is composed by 38 items based on a 5-points Likert Scale. Higher scores (maximum 190) mean optimal acceptability of SUPER within the rehabilitative taking charge, while lower scores (minimum 38) mean a worse level of acceptability.

SUS (System Usability Scale) is a standardized tool for measuring the perceived usability of an interactive system, such as websites, user interfaces, and web applications. It consists of 10 items that are scored on a Likert scale, from 1 (strongly disagree) to 5 (strongly agree). The SUS scores below 68 reveal usability issues with the system, while scores higher than 68 indicate acceptable levels of usability. More specifically, scores over 80 suggest an "excellent" usable system, scores between 68 and 80 can be considered "good", scores between 51 and 68 indicate "fair" results, scores below 51 are "poor", and scores below 36 reflect "unusable" systems.

The Parenting Stress Index-Short Form (PSI-SF) is one of the most commonly used measures of parenting stress both in clinical and research contexts. The PSI-SF is a 36-item, self-report measure with three subscales: Parental Distress (PD), Parent-Child Dysfunctional Interaction (PCDI), and Difficult Child (DC). Items are scored using the following 5-point scale: 1) SA (Strongly Agree); 2) A (Agree); 3) NS (Not Sure); 4) D (Disagree); 5) SD (Strongly Disagree).The normal range of scores is between the 15th and 80th percentile. Scores at or above the 85th percentile are considered high and Defensive Reponding scores at 10 or below are considered extremely low.

Vineland Adaptive Behavior Scales- 2 (VABS-2) is designed to measure adaptive behavior in daily settings for children and adults from birth to 90 years of age. The Vineland-II items are arranged from 11 simple to more complex behavior subdomains across four main domains: Communication, Daily Living Skills, Socialization, and Motor Skills. It also provides an optional Maladaptive Behavior Index. Items are arranged in a developmental sequence within each subdomain, with each item rated on a 3-point scale (i.e., 0 = Behavior Never Performed, 1 = Behavior Sometimes or Partially Performed, or 2 = Behavior Usually or Habitually Performed).

The Adaptive Behavior Composite and domains yield age-based standard scores with a normative M=100 and SD=15, and subdomains yield standard scores with a M=15 and SD=3.
