Note:
Model includes tasks from all phases (i.e., BLERT, ER40, Eyes, Hinting, TASIT)
Model includes tasks administered during all phases with RAD and AIHQ-B
Model includes tasks administered during all phases with IBT-B; Δ indicates change in adjusted R2 after accounting for NC block; VIF values for all predictors across models < 2.5 indicating acceptable multicollinearity, bold values indicate p<.05; SLOF Self-Report not administered during phases Three and Four; AIHQ-B = Ambiguous Intentions and Hostility Questionnaire Blame Index, BLERT-B = Bell Lysaker Emotion Recognition Task, ER40-B = Penn Emotion Recognition Task, Eyes = Reading the Mind in the Eyes Task, Hinting = Hinting Task, IBT-B = Intentionality Bias Task, RAD = Relationship Across Domains Task, TASIT-S = The Awareness of Social Inference Test, SSPA = Social Skills Performance Assessment, SLOF = Specific Levels of Functioning, UPSA-B = UCSD Performance-Based Skills Assessment - Brief.
