The effects of a visual search attentional bias modification paradigm on attentional bias in dysphoric individuals

Abstract

Background and ObjectivesAttentional Bias Modification (ABM) may constitute a new type of treatment for affective disorders. ABM refers to computerized training programs that have been developed based on laboratory findings in experimental psychology. Meta-analyses have reported moderate effect sizes in anxiety disorders. Two small studies have also claimed an effect in dysphoria. Furthermore, a series of studies in individuals with low self-esteem has shown that they benefit from a single session of an ABM variant based on a visual search task. The current study tested the working mechanism of visual search ABM in dysphoria. MethodsForty dysphoric individuals engaged in a single session of ABM training or control training. Attentional bias for positive and negative facial expressions was assessed pre- and post training. Positive and negative mood states were assessed throughout the procedure. ResultsAttentional training had no effect on attentional bias. Positive and negative mood states were not differentially affected by training condition. LimitationsSmall treatment effects may have gone undetected and there are some methodological differences with prior research. ConclusionWe found no evidence that engaging in a single session of a visual search ABM modifies attentional biases for happy, sad or disgusted facial expressions.
