The Acceptance and Action Questionnaire-II (AAQ-II) is a self-report measure designed to assess experiential avoidance as conceptualized in acceptance and commitment therapy (ACT). The current study is the first to evaluate the psychometric properties of the AAQ-II in a large sample of adults (N = 376) with mild to moderate levels of depression and anxiety who participated in a study on the effects of an ACT intervention. The internal construct validity and local measurement precision were investigated by fitting the data to a unidimensional item response theory (IRT) model, and the incremental validity of the AAQ-II beyond mindfulness, as measured by the Five Facet Mindfulness Questionnaire, was assessed. Results of the IRT analyses suggest that the AAQ-II is a unidimensional measure of experiential avoidance and has satisfactory reliability for group comparisons in mild to moderately depressed and anxious populations. Item functioning was found to be independent of gender and slightly dependent on age in this sample. Furthermore, the AAQ-II showed incremental validity beyond 5 mindfulness facets in explaining depression, anxiety, and positive mental health. This study suggests the AAQ-II shows promise as a useful tool for the measurement of experiential avoidance in mild to moderately depressed and anxious populations.
接受与行动问卷-II（AAQ-II）是一种自我报告的测量工具，旨在评估接受与承诺疗法（ACT）中所概念化的经验性回避。本研究是首次在一个有轻度至中度抑郁和焦虑的成年人（N=376）的大样本中评估 AAQ-II 的心理测量特性，他们参加了一项关于 ACT 干预效果的研究。通过将数据拟合到一个单维项目反应理论（IRT）模型，研究了内部结构效度和局部测量精度，评估了 AAQ-II 相对于正念（由五因素正念问卷测量）的增量有效性。IRT 分析的结果表明，AAQ-II 是经验性回避的单维测量工具，在轻度至中度抑郁和焦虑人群中进行群体比较时具有令人满意的可靠性。在该样本中，项目功能被发现独立于性别，而略微依赖于年龄。此外，AAQ-II 在解释抑郁、焦虑和积极心理健康方面表现出超越 5 正念方面的增量有效性。本研究表明，AAQ-II 有望成为衡量轻度至中度抑郁和焦虑人群中经验性回避的有用工具。
