The Social Attribution Task-Multiple Choice (SAT-MC) tests the ability to extract social themes from viewed object motion. This form of animacy perception is thought to aid the development of social inference, but appears impaired in schizophrenia. The current study was undertaken to examine psychometric equivalence of two forms of the SAT-MC and to compare their performance against social cognitive tests recommended for schizophrenia research. Thirty-two schizophrenia (SZ) and 30 substance use disorder (SUD) participants completed both SAT-MC forms, the Bell-Lysaker Emotion Recognition Task (BLERT), Hinting Task, The Awareness of Social Inference Test (TASIT), Ambiguous Intentions and Hostility Questionnaire (AIHQ) and questionnaire measures of interpersonal function. Test sensitivity, construct and external validity, test-retest reliability, and internal consistency were evaluated. SZ scored significantly lower than SUD on both SAT-MC forms, each classifying ~60% of SZ as impaired, compared with ~30% of SUD. SAT-MC forms demonstrated good test-retest and parallel form reliability, minimal practice effect, high internal consistency, and similar patterns of correlation with social cognitive and external validity measures. The SAT-MC compared favorably to recommended social cognitive tests across psychometric features and, with exception of TASIT, was most sensitive to impairment in schizophrenia when compared to a chronic substance use sample.
社会归因任务-多项选择测试（SAT-MC）检验了从观察到的物体运动中提取社会主题的能力。这种生动感知形式被认为有助于社会推理的发展，但在精神分裂症中似乎存在障碍。本研究旨在检验两种形式的 SAT-MC 的心理测量等效性，并将其与推荐用于精神分裂症研究的社会认知测试进行比较。32 名精神分裂症（SZ）和 30 名物质使用障碍（SUD）参与者完成了两种 SAT-MC 形式，贝尔-莱萨克情感识别任务（BLERT）、暗示任务、社会推理意识测试（TASIT）、模糊意图和敌意问卷（AIHQ）以及人际功能问卷。评估了测试的敏感性、结构和外部有效性、测试-重测可靠性以及内部一致性。与 SUD 相比，两种 SAT-MC 形式的 SZ 得分均显著较低，每种形式都将约 60%的 SZ 归类为受损，而 SUD 为约 30%。SAT-MC 形式表现出良好的测试-重测和并行形式可靠性、最小的练习效应、高内部一致性以及与社会认知和外部有效性测量相似的相关模式。SAT-MC 在心理测量特征上与推荐的社会认知测试相比具有优势，并且与 TASIT 不同，与慢性物质使用样本相比，它对精神分裂症的损伤最敏感。
