Abstract

Background: The use of instruments developed for people with autism spectrum disorder (ASD) and intellectual and developmental disabilities (IDDs) is recommended for assessing mental health in these groups. This is the first study to investigate the structural validity and internal consistency of the Psychopathology in Autism Checklist (PAC) among autistic children and adolescents with IDDs.

Methods: A total of 600 children aged 2-19 years (M = 9.2 years, SD = 4.5 years, 66% male) with IDDs (full-scale IQ M = 81.29, SD = 18.65) participated, including 194 individuals with ASD. Parents completed the PAC, Strengths and Difficulties Questionnaire (SDQ) and Vineland Adaptive Behaviour Scales (VABS). Full-scale IQ was assessed using an individualised intelligence test, and the extent of autism characteristics was assessed using the Autism Diagnostic Observation Schedule-2.

Results: Confirmatory factor analyses revealed acceptable fit indices for a three-factor solution. The internal consistency was adequate for most of the PAC subscales. The PAC showed meaningful overlap and differentiation with the SDQ, VABS, measures of intellectual functioning and a measure of autism symptoms.

Conclusions: Overall, satisfactory internal consistency and validity were found for the PAC (with the exception of the psychosis subscale). These findings provide preliminary support for the use of the PAC in children and adolescents with ASD and IDDs.

儿童青少年自闭症心理病理量表的结构效度。

背景：推荐使用为自闭症谱系障碍（ASD）和智力和发育障碍（IDDs）患者开发的工具来评估这些群体的心理健康。本研究首次在自闭症儿童和青少年中探讨自闭症精神病理学量表（PAC）的结构效度和内部一致性。方法：共600例2 ~ 19岁IDDs儿童（M = 9.2岁，SD = 4.5岁，66%为男性）（全量表IQ M = 81.29, SD = 18.65），其中ASD 194例。家长们完成了PAC，优势和困难问卷（SDQ）和Vineland适应行为量表（VABS）。使用个性化智力测验评估全面智商，使用自闭症诊断观察表-2评估自闭症特征的程度。结果：验证性因子分析揭示了三因素解决方案的可接受的拟合指数。大多数PAC分量表的内部一致性是足够的。PAC与SDQ、VABS、智力功能测量和自闭症症状测量显示出有意义的重叠和差异。结论：总体而言，PAC的内部一致性和效度令人满意（精神疾病分量表除外）。这些发现为在患有ASD和IDDs的儿童和青少年中使用PAC提供了初步支持。

期刊介绍： The Journal of Intellectual Disability Research is devoted exclusively to the scientific study of intellectual disability and publishes papers reporting original observations in this field. The subject matter is broad and includes, but is not restricted to, findings from biological, educational, genetic, medical, psychiatric, psychological and sociological studies, and ethical, philosophical, and legal contributions that increase knowledge on the treatment and prevention of intellectual disability and of associated impairments and disabilities, and/or inform public policy and practice. Expert reviews on themes in which recent research has produced notable advances will be included. Such reviews will normally be by invitation.
