Note. Means, standard deviations, and between-group comparisons on demographic and primary measures. BDI-II = Beck Depression Inventory, 2nd Edition; SRS-2 = Social Responsiveness Scale, 2nd Edition, SCI = Social Communication and Interaction, RRB = Restricted Interests and Repetitive Behavior (though we used raw SRS-2 scores in our analyses, T scores are reported above for interpretability); ACIPS = Anticipatory and Consummatory Interpersonal Pleasure Scale; TEPS = Temporal Experience of Pleasure Scale; LiCQ = Loneliness in Context Questionnaire; ADOS-2 = Autism Diagnostic Observation Schedule, 2nd Edition; CS=ADOS-2 Comparison Score on 1–10 metric.
