This study examined the role of experiential avoidance and difficulties engaging in goal-directed behavior when distressed in the relationship between anxiety sensitivity (AS) and depressive symptom severity. A sample of 391 undergraduate students completed a series of questionnaires assessing the constructs of interest. Results provided support for a model where experiential avoidance and difficulties engaging in goal-directed behavior mediate the relationship between the AS dimensions of fear of cognitive dyscontrol and fear of publicly observable anxiety reactions and depressive symptom severity. The ability of this model to distinguish participants (N=53) reporting clinical levels of depression from those without (N=53) was then examined. The model was found to reliably distinguish between participants with and without clinical levels of depression. However, only experiential avoidance was a significant mediator. Implications for research on the role of AS in depression vulnerability and treatment are discussed.
本研究考察了在焦虑敏感性（AS）与抑郁症状严重程度之间的关系中，经验性回避以及在痛苦时难以进行目标导向行为所起的作用。391名本科生样本完成了一系列评估相关构念的问卷。结果支持了这样一个模型：经验性回避和难以进行目标导向行为在对认知失控的恐惧和对公开可见焦虑反应的恐惧这两个AS维度与抑郁症状严重程度之间起中介作用。然后检验了该模型区分报告临床水平抑郁的参与者（N = 53）和未报告临床水平抑郁的参与者（N = 53）的能力。发现该模型能够可靠地区分有和没有临床水平抑郁的参与者。然而，只有经验性回避是一个显著的中介变量。文中讨论了AS在抑郁易感性和治疗中的作用的研究意义。
