The Attentional Control Scale for Children (ACS-C) is a widely used self-report questionnaire that measures attentional control in youth. Previous research examined factor-structure and validation of the ACS-C and yielded a 2-factor structure with Attentional Focusing and Attentional Shifting subscales. This study used a confirmatory factor analysis in a large, ethnically diverse sample of clinic-referred anxious youth (N = 442, ages 7-16 years) to compare model fit of three models, the original two-factor model of the ACS-C, a two-factor model of a modified ACS-C (two items re-assigned from Attentional Focusing to Attentional Shifting, three items removed from Attentional Focusing, and two items removed from Attentional Shifting), and a single-factor model. Results reveal best model fit for the two-factor modified ACS-C. This model had strong factorial invariance across sex, partial invariance across ethnicity, and was variant across age. Also, total and subscale scores for the two-factor modified ACS-C correlated with anxiety and depression symptom scale scores, supporting its concurrent validity. Findings confirm the two-factor structure of the modified ACS-C. Future research implications relating to attentional control in children are discussed.
儿童注意控制量表（ACS-C）是一种广泛使用的自评问卷，用于衡量青少年的注意力控制。先前的研究检验了 ACS-C 的因子结构和验证，并得出了具有注意力集中和注意力转移两个分量表的 2 因素结构。本研究在一个由临床转诊的焦虑青少年组成的大型、种族多样化的样本中（N=442，年龄 7-16 岁），使用验证性因素分析比较了三种模型的拟合优度，即 ACS-C 的原始两因素模型、修改后的 ACS-C 的两因素模型（将两个项目从注意力集中重新分配到注意力转移，从注意力集中中删除三个项目，从注意力转移中删除两个项目）和单因素模型。结果表明，修改后的 ACS-C 的两因素模型具有最佳的模型拟合度。该模型在性别、种族和年龄方面具有较强的因子不变性。此外，两因素修改后的 ACS-C 的总分和分量表得分与焦虑和抑郁症状量表得分相关，支持其同时效度。研究结果证实了修改后的 ACS-C 的两因素结构。讨论了与儿童注意力控制相关的未来研究意义。
