注意控制量表（ACS; Derryberry & Reed, 2002）在许多研究中被用来评估对注意力的执行控制，但没有发表的数据检验英文版的因素结构。目前的研究解决了这一需求，并测试了ACS子量表的预测和收敛效度。在研究1中，探索性因子分析得到了一个双因子模型，其中包括聚焦和转移子量表。在研究2中，验证性因子分析支持该模型，并表明与冰岛版本的因子结构相比，该模型具有更好的拟合性（Olafsson et al., 2011）。研究3检验了ACS量表与工作记忆、焦虑和认知控制测量之间的相关性。研究4检验了混合反扫视任务的子量表和反应时间之间的相关性，揭示了反扫视性能和进程延迟与聚焦得分之间的正相关，以及切换试验性能和转移得分之间的正相关。此外，这些发现部分支持了最近研究中注意到的专注和特质焦虑之间以及转移和抑郁之间的独特关系。虽然结果总体上支持ACS的有效性，但需要使用基于绩效的任务进行额外的研究。
The Attentional Control Scale (ACS; Derryberry & Reed, 2002) has been used to assess executive control over attention in numerous studies, but no published data have examined the factor structure of the English version. The current studies addressed this need and tested the predictive and convergent validity of the ACS subscales. In Study 1, exploratory factor analysis yielded a two-factor model with Focusing and Shifting subscales. In Study 2, confirmatory factor analysis supported this model and suggested superior fit compared to the factor structure of the Icelandic version (Olafsson et al., 2011). Study 3 examined correlations between the ACS subscales and measures of working memory, anxiety, and cognitive control. Study 4 examined correlations between the subscales and reaction times on a mixed-antisaccade task, revealing positive correlations for antisaccade performance and prosaccade latency with Focusing scores and between switch trial performance and Shifting scores. Additionally, the findings partially supported unique relationships between Focusing and trait anxiety and between Shifting and depression that have been noted in recent research. Although the results generally support the validity of the ACS, additional research using performance-based tasks is needed.
