Attentional bias modification based on visual probe task: methodological issues, results and clinical relevance.

INTRODUCTION Attentional bias, the tendency that a person has to drive or maintain attention to a specific class of stimuli, may play an important role in the etiology and persistence of mental disorders. Attentional bias modification has been studied as a form of additional treatment related to automatic processing. OBJECTIVES This systematic literature review compared and discussed methods, evidence of success and potential clinical applications of studies about attentional bias modification (ABM) using a visual probe task. METHODS The Web of Knowledge, PubMed and PsycInfo were searched using the keywords attentional bias modification, attentional bias manipulation and attentional bias training. We selected empirical studies about ABM training using a visual probe task written in English and published between 2002 and 2014. RESULTS Fifty-seven studies met inclusion criteria. Most (78%) succeeded in training attention in the predicted direction, and in 71% results were generalized to other measures correlated with the symptoms. CONCLUSIONS ABM has potential clinical utility, but to standardize methods and maximize applicability, future studies should include clinical samples and be based on findings of studies about its effectiveness.
