本研究以69名年龄在18-40岁的成年人为样本，评估了社会沟通问卷（SCQ）的有效性。参与者包括21名被诊断为自闭症谱系障碍（ASD）和智力残疾（ID）的成年人，以及48名被诊断为自闭症谱系障碍但未被诊断为ASD的人。SCQ的灵敏度为。的专一性。77分，作者建议的分界点是15分（Berument et al., 1999）。然而，当敏感性优先于特异性时，最佳临界值为12，即敏感性为。特异性为0.60。总量表（alpha= 0.87）、社会互动量表（alpha= 0.83）和限制性重复行为量表（alpha= 0.81）的内部一致性较好，而沟通量表（alpha= 0.48）的内部一致性较差。SCQ有望成为早期发育历史可能无法获得的成人ID的筛查措施。建议在成人中采用比作者最初建议的更低的临界值。(C) 2012 Elsevier Ltd.版权所有。
This study assessed the validity of the Social Communication Questionnaire (SCQ) in a sample of 69 adults, aged 18-40 years old. Participants included 21 adults diagnosed with an autism spectrum disorder (ASD) and intellectual disability (ID), and 48 individuals diagnosed with ID and no diagnosis of an ASD. The SCQ yielded a sensitivity of .71 and a specificity of .77 at the authors' recommended cutoff score of 15 (Berument et al., 1999). However, when sensitivity was prioritized over specificity, the optimal cutoff score was 12, which yielded a sensitivity of .86 and a specificity of .60. The internal consistencies of the total scale (alpha=.87), the social interaction subscale (alpha=.83), and the restricted repetitive behavior subscale (alpha=.81) were good, but the communication subscale performed poorly (alpha=.48). The SCQ shows promise as a screening measure for adults with ID whose early developmental history may be unavailable. A lower cutoff score than the authors originally proposed is recommended in adults. (C) 2012 Elsevier Ltd. All rights reserved.
