Abstract

Objective: Repetitive negative thinking (RNT) e.g., worry in generalized anxiety disorder (GAD) and rumination in depression, is often targeted during psychological treatments. To test the hypothesis that negative interpretation bias contributes to worry and rumination, we assessed the effects of inducing more positive interpretations in reducing RNT.
Method: Volunteers diagnosed with GAD (66) or Depression (65) were randomly allocated to one of two versions of Cognitive Bias Modification (CBM-I), either with or without RNT priming prior to training), or a control condition, each involving 10 internet-delivered sessions. Outcome measures of interpretation bias, a behavioral RNT task and self-reported worry, rumination, anxiety and depression were obtained at baseline, after home-based training and at 1-month follow up (self-report questionnaires only). Results: CBM-I training, across diagnostic groups, promoted a more positive interpretation bias and led to reductions in worry, rumination, and depressive symptoms, which were maintained at follow up. Anxiety symptoms were reduced only in the GAD group at follow up. There were no differences between CBM-I versions; brief priming of RNT did not influence CBM-I effectiveness. Level of interpretation bias post training partially mediated the effects of CBM-I on follow-up questionnaire scores. Conclusions: In contrast to some recent failures to demonstrate improvements following internet-delivered CBM, we found that self-reported RNT and negative mood were reduced by CBM-I. This is consistent with a causal role for negative interpretation bias in both worry and rumination, suggesting a useful role for CBM-I within treatments for anxiety and depression.
