Deficits in social cognition are common in psychiatric disorders. Validated social cognition measures with good psychometric properties are necessary to assess and target social cognitive deficits. Two recent social cognition tests, the Combined Stories Test (COST) and the Social Knowledge Test (SKT), respectively assess theory of mind and social knowledge. Previous studies have shown good psychometric properties for these tests, but the test-retest reliability has never been documented. The aim of this study was to evaluate the test-retest reliability and the inter-rater reliability of the COST and the SKT. The COST and the SKT were administered twice to a group of forty-two healthy adults, with a delay of approximately four weeks between the assessments. Excellent test-retest reliability was observed for the COST, and a good test-retest reliability was observed for the SKT. There was no evidence of practice effect. Furthermore, an excellent inter-rater reliability was observed for both tests. This study shows a good reliability of the COST and the SKT that adds to the good validity previously reported for these two tests. These good psychometrics properties thus support that the COST and the SKT are adequate measures for the assessment of social cognition.
社会认知缺陷在精神障碍中很常见。为了评估和针对社会认知缺陷，有必要使用具有良好心理测量学特性的经过验证的社会认知测量方法。最近的两项社会认知测试，即联合故事测试（COST）和社会知识测试（SKT），分别评估心理理论和社会知识。先前的研究表明这些测试具有良好的心理测量学特性，但测试-重测信度从未被记录过。本研究旨在评估 COST 和 SKT 的测试-重测信度和评分者间信度。COST 和 SKT 被两次施测给 42 名健康成年人，两次评估之间大约有四周的时间间隔。COST 观察到极好的测试-重测信度，SKT 观察到良好的测试-重测信度。没有证据表明存在练习效应。此外，两项测试都观察到了极好的评分者间信度。本研究表明 COST 和 SKT 具有良好的信度，这增加了之前报道的这两种测试的良好有效性。因此，这些良好的心理计量学特性支持 COST 和 SKT 是评估社会认知的合适方法。
