To examine the factor structure of autism spectrum disorder (ASD) and the psychometric properties of the German Symptom Checklist for Autism Spectrum Disorders (SCL-ASD). Data were collected from 312 clinical referrals with suspected ASD (2-18 years). Confirmatory factor analyses and analyses of reliability, convergent and divergent validity were performed. A bifactor model with one general ASD factor and two specific factors (interaction-communication; restricted, repetitive behaviors) provided an adequate data fit. Internal consistencies of the SCL-ASD subscales and the total scale were > .70. Correlations with measures of ASD traits were higher than correlations with measures of externalizing and internalizing symptoms. The results support a factor structure consistent with DSM-5/ICD-11 criteria. The SCL-ASD has sound psychometric properties.
检验自闭症谱系障碍（ASD）的因子结构和德国自闭症谱系障碍症状清单（SCL-ASD）的心理计量学特性。数据来源于 312 名疑似 ASD 的临床转诊患者（2-18 岁）。进行了验证性因子分析和可靠性、聚合和发散效度分析。具有一个一般 ASD 因子和两个特定因子（交互-沟通；受限、重复行为）的双因素模型提供了较好的数据拟合。SCL-ASD 分量表和总量表的内部一致性系数均大于.70。与 ASD 特征测量的相关性高于与外部和内部症状测量的相关性。结果支持与 DSM-5/ICD-11 标准一致的因子结构。SCL-ASD 具有良好的心理计量学特性。
