Abstract

Both dysfunctional and self-efficacy-related cognitions are theorized as etiological and maintaining factors in agoraphobia. Exposure therapy is an effective treatment and central component of CBT for agoraphobia, but the role of changes in these cognitions as a mechanism of action has not been established. The present review aims to evaluate (a) whether exposure without cognitive interventions elicits changes in cognitive variables and (b) whether cognitive changes mediate outcomes in exposure-based treatments. We searched PsycInfo and PubMed for studies on agoraphobia (with or without panic disorder) and exposure as a treatment component. Fifteen articles with 29 relevant study arms (N = 921) were identified for a meta-analysis of cognitive changes after exposure. Seventeen articles (N = 1881) were included in a systematic narrative review of cognitive mediation. A random effects model revealed a large effect of cognitive improvement after pure exposure treatments, d = 1.02 (95% CI 0.81-1.23). The systematic review mostly supported changes in cognition as mediators of symptom change. Improved study designs and statistical methods in future mediation studies are needed to strengthen causal interpretation. Cognitive change is a...Continue Reading
