The Impact of Optimism and Pain Interference on Response to Online Behavioral Treatment for Mood and Anxiety Symptoms.

Objective: This study aimed to explore a) if high pain interference has a negative effect on response to computerized cognitive behavioral therapy (cCBT) for anxiety and depression and b) whether high optimism can buffer the negative effects of pain interference on cCBT outcomes.

Methods: We performed a secondary analysis of data on 403 participants from the randomized controlled clinical trial "Online Treatment for Mood and Anxiety Disorders in Primary Care." It examined the impact of cCBT, with and without access to an Internet support group, on health-related quality of life (HRQoL), mood, and anxiety symptoms.
