The Spence Children’s Anxiety Scale (SCAS) has demonstrated good psychometric properties in several countries and cultures. Nevertheless, most of the previous studies that explore these properties have combined clinical and community samples. We aimed to validate the Spanish version of the SCAS in a large clinical sample (N = 130) of children and adolescents. The Spanish adaptation of the SCAS showed good internal consistency for the total scale, and good test-retest reliability for all the subscales. Furthermore, its convergent and discriminant validity were supported by significant correlations with other anxiety questionnaires (Screen for Child Anxiety Related Emotional Disorders [SCARED], Youth Self-Report [YSR] subscales for anxiety disorders and internalizing symptomatology), and lower or non-significant correlations with depression symptoms and externalizing symptoms scales respectively. For the first time in a purely clinical sample, the original factor structure of the SCAS based on six correlated factors was confirmed. Future studies need to evaluate whether the factorial structure of the present instrument is the most suitable for use in clinical populations.

西班牙临床样本中儿童版 Spence 儿童焦虑量表 (SCAS) 的心理测量特性

Spence 儿童焦虑量表 (SCAS) 在多个国家和文化中表现出良好的心理测量特性。尽管如此，之前探索这些特性的大多数研究都结合了临床和社区样本。我们的目的是在大型临床样本中验证 SCAS 的西班牙语版本（ñ= 130) 的儿童和青少年。SCAS 的西班牙改编版在总量表上表现出良好的内部一致性，在所有分量表上都表现出良好的重测信度。此外，它的收敛效度和区分效度得到了与其他焦虑问卷（儿童焦虑相关情绪障碍筛查 [SCARED]、青少年自我报告[YSR] 焦虑障碍和内化症状的分量表），分别与抑郁症状和外化症状量表的相关性较低或不显着。首次在纯临床样本中确认了基于六个相关因素的 SCAS 的原始因子结构。未来的研究需要评估本仪器的阶乘结构是否最适合临床人群使用。
