Anxiety sensitivity (AS) is an established cognitive risk factor for anxiety disorders. In children and adolescents, AS is usually measured with the Childhood Anxiety Sensitivity Index (CASI). Factor analytic studies suggest that the CASI is comprised of 3 lower-order factors pertaining to Physical, Psychological and Social Concerns. There has been little research on the validity of these lower-order factors. We examined the concurrent and incremental validity of the CASI and its lower-order factors in a non-clinical sample of 349 children and adolescents. CASI scores predicted symptoms of DSM-IV anxiety disorder subtypes as measured by the Spence Children's Anxiety Scale (SCAS) after accounting for variance due to State-Trait Anxiety Inventory scores. CASI Physical Concerns scores incrementally predicted scores on each of the SCAS scales, whereas scores on the Social and Psychological Concerns subscales incrementally predicted scores on conceptually related symptom scales (e.g. CASI Social Concerns scores predicted Social Phobia symptoms). Overall, this study demonstrates that there is added value in measuring AS factors in children and adolescents.
焦虑敏感性（AS）是焦虑症已确定的认知风险因素。在儿童和青少年中，AS通常用儿童焦虑敏感性指数（CASI）来衡量。因素分析研究表明，CASI由与身体、心理和社会担忧相关的3个低阶因素组成。关于这些低阶因素的有效性研究较少。我们在349名儿童和青少年的非临床样本中检验了CASI及其低阶因素的同时效度和增量效度。在考虑了状态-特质焦虑量表得分造成的方差后，CASI得分预测了斯宾斯儿童焦虑量表（SCAS）所测量的DSM-IV焦虑症亚型症状。CASI身体担忧得分逐步预测了SCAS各量表的得分，而社会和心理担忧子量表的得分逐步预测了概念上相关症状量表的得分（例如，CASI社会担忧得分预测社交恐惧症症状）。总体而言，本研究表明，在测量儿童和青少年的AS因素方面具有附加价值。
