ABI:62-item questionnaire to track outcomes in autism spectrum disorder (ASD). Each item was answered on 1 of 2 possible dimensions: quality (how well person carries out particular behavior; 1 to 13 items) or frequency (how often particular behavior occurs; 14 to 62 items). Each item was rated on scale of 0 (never) to 3 (very often) for frequency and 0 (without help) to 3 (not at all) for quality. Higher score=severe symptoms/more frequency. ABI core domain score was from 2 domains: social communication (23 items; 3 sub-domains) and repetitive/restrictive behavior (RRB;15 items; 4 sub-domains). Domain and sub-domain scores: calculated as average of non-missing items (ie, sum of all non-missing items divided by number of non-missing items); scores ranged from 0 to 3, higher scores=more severe symptoms of ASD. ABI core domain score=sum of social communication and RRB domain scores divided by total number of items in these 2 domains. Negative changes in ABI core domain score=improvement.

ABI was 62-item questionnaire completed on a web/mobile application or on paper. It tracks outcomes in ASD. Each ABI item was answered on 1 of 2 possible dimensions, quality (how well a person carries out a particular behavior; 1 to 13 items) or frequency (how often a particular behavior occurs; 14 to 62 items). Each item was rated on scale of 0 (never) to 3 (very often) for frequency and 0 (without help) to 3 (not at all) for quality. Higher score indicated severe symptoms/more frequency. The ABI social communication domain score consisted of 23 items; with 3 sub-domains. The domain and sub-domain scores were calculated as the average of the non-missing items (ie, sum of all non-missing items divided by the number of non-missing items). For both domains and its sub-domains, scores ranged from 0 to 3 with higher scores indicating more severe symptoms of ASD. Negative change in score indicates improvement.

SRS-2: 65-item scale measured extent of autistic social impairment and included 5 subscales: social awareness, social cognition, social communication, social motivation, and restricted interests and repetitive behavior. Each of 65 items had 4 responses: not true, sometimes true, often true, and almost always true. Scoring value for each item was 0 to 3. If a response to an item was missing, then pre-defined median value for item (0 or 1) was imputed. SRS-2 was not scored if 7 or more item responses were missed. Total raw score was sum of item response values. Each subscale was obtained by adding response values and converted total raw score to standardized T-score based on gender and rater (parent or caregiver). Total T-score was categorized: within normal limits (\<=59), mild (60 to 65), moderate (66 to 75) and severe (\>=76). For total score T-score, higher scores=more severe symptoms. SRS T-score had mean of 50 and standard deviation of 10. Negative changes in T-scores=improvement.

HDRS17 is clinician-administered rating scale designed to assess severity of symptoms in participants diagnosed with depression. Each of 17 items is rated by clinician on either 3-point (0-2) or 5-point (0-4) scale with rating of 0: absent, 1: doubtful to mild, 2: mild to moderate, 3: moderate to severe, and 4: very severe. A total score (0 to 52) was calculated by adding scores of all 17 items. For each item as well as total score, higher score represents more severe condition.

HDRS17 is a clinician-administered rating scale designed to assess severity of symptoms in participants diagnosed with depression. Each of the 17 items is rated by clinician on either a 3-point (0 to 2) or a 5-point (0 to 4) scale which used a rating of 0: absent, 1: doubtful to mild, 2: mild to moderate, 3: moderate to severe, and 4: very severe. HDRS17 total score is calculated as sum of 17 item scores and ranges from 0 to 52. For each item as well as the total score, higher scores indicate greater severity of depression.

The LSAS is a 24-item, semi-structured interview on the severity of Social Anxiety Disorder. The LSAS separately assesses fear and avoidance of 24 social situations. The scale is divided into 2 subscales, 13 situations concerning performance anxiety, and 11 situations pertaining to social situations. The 24 items are first rated on a Likert Scale from 0 to 3 on fear felt during the situations (0=none, 1=mild, 2=moderate, 3= severe), and then the same items are rated regarding avoidance of the situation (0=never, 1=occasionally, 2=often, 3=usually) with higher scores indicating greater social anxiety. The LSAS fear/anxiety and avoidance subscale was calculated by summing the 24 fear/anxiety and avoidance item scores of the LSAS, and ranges from 0 to 72. Combining the total scores for the Fear and Avoidance sections provides an overall score with a maximum of 144 points and a minimum of 0 points. Higher scores indicated higher probability of social anxiety disorder (SAD).
