Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Abstract

Background: Cognitive bias modification (CBM), targeting attentional biases (ABM) or interpretation biases (CBMI), are prototypical examples of mechanistically derived treatments, but their effectiveness is contentious. We examined the relative effectiveness of CBM for anxious and depressive symptomatology.

Methods: For this systematic review and network meta-analysis (NMA), we searched PubMed, PsycINFO, EMBASE and Cochrane Central Register through January 15 th 2019, We included randomized controlled trials of CBM versus control conditions for adults with clinical or subclinical anxiety or depression. Two researchers independently selected studies and evaluated risk of bias with the Cochrane Collaboration tool. Primary outcomes encompassed anxiety and depression in trials targeting these conditions. We computed standardized mean differences (SMD) with a restricted maximum likelihood random effects model.

Findings: From 1665 records, we selected 82 trials, 65 (N=3788) on anxiety and 17 (N= 863) on depression. In a well-connected network of anxiety trials, CBMI outperformed waitlist (SMD = -0·48, 95% CI: -0·84 to -0·12) and sham training (SMD = -0·31, 95% CI: -0·53 to -0·09) for the primary outcome. ABM showed benefits only in sensitivity analyses excluding PTSD trials. Prediction intervals were large, including an SMD of 0. Networks of depression trials displayed evidence of inconsistency.

Interpretation: CBM interventions showed consistent but small benefits, however heterogeneity and risk of bias undermine the reliability of these findings. Larger, definitive trials for CBMI for anxiety might be warranted. Insufficient evidence precludes conclusions for depression.
