Few autism spectrum disorder (ASD) screening tools have been developed and validated in Africa. This study aimed to examine the psychometric properties of the Social Communication Questionnaire (SCQ) when used with Nigerian adolescents. Parents and caregivers of two hundred and five adolescents completed the SCQ Lifetime form while the adolescents were assessed for ASD using the Autism Diagnostic Observation Schedule, 2nd Edition (ADOS-2). Factor structure and convergent and discriminative validity were examined, along with the sensitivity and specificity of the SCQ in identifying participants with an autism spectrum disorder. The confirmatory factor analysis (CFA) was used to examine the factor structure, while logistic regression and Pearson's correlation coefficient were used to examine the validities. The SCQ had good internal consistency, discriminative, and convergent validity. A cut-off score of 10 revealed sensitivity = 0.81 and specificity = 0.88 for the identification of autism spectrum disorder. AUC was 0.83, p < 0.001, 95% CI [0.77, 0.90]. The results of this study provide evidence to support the retention of the original four factors of the SCQ. The SCQ has good psychometric properties when used with Nigerian adolescents.
自闭症谱系障碍 (ASD) 的筛查工具在非洲开发和验证的很少。本研究旨在考察社会交往问卷 (SCQ) 在尼日利亚青少年中的心理测量特性。205 名青少年的父母和照顾者完成了 SCQ 终身形式，而青少年则使用自闭症诊断观察量表，第二版 (ADOS-2) 进行 ASD 评估。同时考察了因子结构和收敛和判别效度，以及 SCQ 在识别自闭症谱系障碍参与者方面的敏感性和特异性。验证性因子分析 (CFA) 用于检验因子结构，而逻辑回归和 Pearson 相关系数用于检验效度。SCQ 具有良好的内部一致性、判别和收敛效度。截断值为 10 时，对自闭症谱系障碍的识别灵敏度为 0.81，特异性为 0.88。AUC 为 0.83，p < 0.001，95%CI [0.77, 0.90]。本研究结果为保留 SCQ 的原始四个因素提供了证据。SCQ 在尼日利亚青少年中具有良好的心理测量特性。
