The relationship between momentary experiential avoidance and anxiety symptoms.

ABSTRACT

BACKGROUND: Experiential avoidance (EA) may serve as a risk factor for a wide range of anxiety-related psychopathology. Anxiety is thought to trigger the use of EA, while also serving as a consequence of EA efforts. Previous ecological momentary assessment (EMA) studies found that EA was associated with greater anxiety in nonclinical undergraduates and patients with social anxiety disorder. METHODS: The present study examined the in-the-moment, bidirectional relationship between EA, perceived stress, and two facets of anxiety (autonomic arousal and worry/misery) in a sample of treatment-seeking patients broadly diagnosed with an anxiety-related disorder (N = 46). Participants completed a baseline assessment followed by an EMA assessment period (assessments three times daily for seven days). We hypothesized that there would be a bidirectional relationship between EA and anxiety/stress. RESULTS: Results largely supported a unidirectional relationship such that greater EA at one time point predicted higher stress at a later time point controlling for previous stress levels and linear time. Trend-level associations between EA and anxiety symptoms are discussed. CONCLUSIONS: The current study provides important insight into the relationship between EA and anxiety symptoms in a clinical sample of participants with anxiety-related disorders.
