The aim of the current study was to investigate the psychometric properties of the BASC-2 (Behavior Assessment System for Children, Second Edition) Atypicality subscale in a sample of adolescents receiving mental health services.
A large sample (n = 1916) of adolescents aged 12-20 years (median = 14.7 years) completed the BASC-2. A parent and teacher also completed the measure for each child. We analyzed internal consistency and interrater reliabilities for the Atypicality subscale, as well as the Depression and Hyperactivity subscales for comparison. Further analyses explored the influence of a participant's subscale scores, gender, and quality of relationships with adults on interrater agreement.
All subscales demonstrated good internal consistency; however, interrater agreement was low for all subscales. Gender, Atypicality subscale score, and self-reported quality of relationships with adults could not account for poor interrater agreement.
The Atypicality subscale has strong internal consistency across informants. Low interrater agreement for the Atypicality subscale, as well as other scales, however, presents a challenge when interpreting multi-informant scales.
本研究旨在调查心理健康服务中青少年样本中 BASC-2（儿童行为评估系统，第二版）非典型性分量表的心理计量学特性。
对 1916 名 12-20 岁的青少年（中位数=14.7 岁）进行了大样本分析。每位儿童的父母和老师都完成了该测试。我们分析了非典型性分量表的内部一致性和评分者间信度，以及抑郁和多动分量表进行比较。进一步的分析探讨了参与者的分量表分数、性别以及与成年人关系的质量对评分者间一致性的影响。
所有分量表均表现出良好的内部一致性；然而，所有分量表的评分者间一致性均较低。性别、非典型性分量表得分和自我报告的与成年人的关系质量不能解释评分者间的低一致性。
非典型性分量表在不同的信息提供者中具有很强的内部一致性。然而，非典型性分量表以及其他量表的评分者间低一致性在解释多信息提供者量表时带来了挑战。
