Distress and avoidance in generalized anxiety disorder: exploring the relationships with intolerance of uncertainty and worry.
Theory and research suggest that treatments targeting experiential avoidance may enhance outcomes for patients with generalized anxiety disorder (GAD). The present study examined the role of experiential avoidance and distress about emotions in a treatment-seeking sample with a principal diagnosis of GAD compared with demographically matched nonanxious controls and sought to explore their shared relationship with two putative psychopathological processes in GAD: intolerance of uncertainty and worry. Patients with GAD reported significantly higher levels of experiential avoidance and distress about emotions compared with nonclinical controls while controlling for depressive symptoms, and measures of these constructs significantly predicted GAD status. Additionally, experiential avoidance and distress about anxious, positive, and angry emotions shared unique variance with intolerance of uncertainty when negative affect was partialed out, whereas only experiential avoidance and distress about anxious emotions shared unique variance with worry. Discussion focuses on implications for treatment as well as future directions for research.
