摘要

儿童最早可在 3 岁时被确诊为自闭症,并开始接受早期干预。在非洲,发病年龄(2-3 岁)与诊断年龄(8-10 岁)之间往往存在很大差距。我们在肯尼亚农村地区开展了一项研究,以验证社会交流问卷 (SCQ) 作为筛查工具的有效性。这项研究在肯尼亚沿海地区进行。研究参与者包括 172 名被诊断患有神经发育障碍 (NDD) 的儿童(其中 84 名患有自闭症)和 112 名对照组儿童。通过使用 Cronbach's alpha、确证因子分析(CFA)和最大似然法评估 SCQ 的概念模型,对内部一致性进行了评估。此外,还利用 ROC 分析评估了截断分数的敏感性和特异性,并利用 IRT 框架评估了项目难度和辨别质量。因子分析显示,DSM-IV-TR 的三因子模型(均方根近似误差(RMSEA)= 0.050;比较拟合指数(CFI)= 0.974;塔克-刘易斯指数(TLI)= 0.973)和 DSM-5 的双因子因子结构(RMSEA = 0.050;CFI = 0.972;TLI = 0.974)具有充分的拟合模型。全组所有项目(Cronbach's α = 0.90)和所有三个领域(Cronbach's α = 0.68-0.84)的信度系数均为可接受到优秀。与典型发育组相比,推荐的 15 分临界值在 ASD 组中产生了 72% 的灵敏度和 100% 的特异性。我们提供了 SCQ 充分的因子结构和良好的内部一致性的早期证据。我们还注意到,推荐的临界值具有足够的预测效力。

Evaluation of the Psychometric Properties of the Social Communication Questionnaire in Rural Kenya.

Evaluation of the Psychometric Properties of the Social Communication Questionnaire in Rural Kenya.

Children can be reliably diagnosed with autism as early as 3 years of age, and early interventions are initiated. There is often a significant gap between the age of onset of symptoms (2-3 years) and diagnosis (8-10 years) in Africa. We conducted a study to validate the Social Communication Questionnaire (SCQ) as a screening instrument in a rural setting in Kenya. The study was conducted along the Kenyan Coast. Study participants included 172 children with a neurodevelopmental disorder (NDD) diagnosis (84 of which were autism) and 112 controls. Internal consistency was evaluated through the use of Cronbach's alpha, confirmatory factor analysis (CFA) with maximum likelihood procedure to assess the conceptual model for the SCQ. Additionally, the sensitivity and specificity of cut-off scores using ROC analysis and item difficulties and discrimination quality using an IRT framework were also assessed. Factor analysis revealed an adequate fitting model for the three-factor DSM-IV-TR (root mean squared error of approximation (RMSEA) = 0.050; Comparative Fit Index (CFI) = 0.974; Tucker-Lewis Index (TLI) = 0.973) and two-factor DSM-5 factor structure (RMSEA = 0.050; CFI = 0.972; TLI = 0.974). The reliability coefficient alphas for the whole group for all items (Cronbach's α = 0.90) and all three domains (Cronbach's α = 0.68-0.84) were acceptable to excellent. The recommended cut-off score of 15 yielded 72% sensitivity and 100% specificity in the ASD group compared to the typically developing group. We provide early evidence of the adequate factor structure and good internal consistency of the SCQ. We also note that the recommended cut-off yielded sufficient predictive validity.

期刊介绍: The Journal of Autism and Developmental Disorders seeks to advance theoretical and applied research as well as examine and evaluate clinical diagnoses and treatments for autism and related disabilities. JADD encourages research submissions on the causes of ASDs and related disorders, including genetic, immunological, and environmental factors; diagnosis and assessment tools (e.g., for early detection as well as behavioral and communications characteristics); and prevention and treatment options. Sample topics include: Social responsiveness in young children with autism Advances in diagnosing and reporting autism Omega-3 fatty acids to treat autism symptoms Parental and child adherence to behavioral and medical treatments for autism Increasing independent task completion by students with autism spectrum disorder Does laughter differ in children with autism? Predicting ASD diagnosis and social impairment in younger siblings of children with autism The effects of psychotropic and nonpsychotropic medication with adolescents and adults with ASD Increasing independence for individuals with ASDs Group interventions to promote social skills in school-aged children with ASDs Standard diagnostic measures for ASDs Substance abuse in adults with autism Differentiating between ADHD and autism symptoms Social competence and social skills training and interventions for children with ASDs Therapeutic horseback riding and social functioning in children with autism Authors and readers of the Journal of Autism and Developmental Disorders include sch olars, researchers, professionals, policy makers, and graduate students from a broad range of cross-disciplines, including developmental, clinical child, and school psychology; pediatrics; psychiatry; education; social work and counseling; speech, communication, and physical therapy; medicine and neuroscience; and public health.
