The current study sought to investigate measurement discrepancies in self-report assessment of experiential avoidance (EA). Recent research indicates that EA may be more appropriately conceptualized as a multidimensional construct, operationally defined in terms of specific avoidance strategies. To test this notion, EA was measured using two self-report assessment instruments, the Acceptance and Action Questionnaire-II (AAQ-II) and the Multidimensional Experiential Avoidance Questionnaire (MEAQ) in a convenience sample of university students. Measurement differences across measures and unique contributions to prediction of posttraumatic stress symptoms (PTSS) and engagement in problematic behaviors were evaluated. Both the AAQ-II and MEAQ were found to significantly mediate the effect of childhood trauma exposure on PTSS. However, when levels of PTSS were dummy coded into dichotomies of those with a likely PTSD diagnosis and those without, the MEAQ was a stronger predictor symptoms of those with a likely PTSD diagnosis than AAQ-II did. These results provide initial support for the discriminant validity of the MEAQ, which appears to be a more specific predictor of trauma-related symptoms.
本研究旨在调查经验性回避（EA）自我报告评估中的测量差异。近期研究表明，EA可能更适合被概念化为一个多维结构，根据特定的回避策略进行操作性定义。为了验证这一观点，在一个大学生便利样本中，使用两种自我报告评估工具，即接受与行动问卷第二版（AAQ-II）和多维经验性回避问卷（MEAQ）对EA进行测量。评估了各测量方法之间的测量差异以及对创伤后应激症状（PTSS）预测和问题行为参与的独特贡献。发现AAQ-II和MEAQ均显著介导了童年创伤暴露对PTSS的影响。然而，当将PTSS水平虚拟编码为可能患有创伤后应激障碍（PTSD）诊断者和未患诊断者的二分法时，对于可能患有PTSD诊断者，MEAQ比AAQ-II是更强的症状预测指标。这些结果为MEAQ的区分效度提供了初步支持，MEAQ似乎是创伤相关症状更具体的预测指标。
