Biased attention and dysphoria: Manipulating selective attention reduces subsequent depressive symptoms

Selective attention for dysphoric stimuli has been observed in individuals with depression and those at risk for depression. To date, no studies have investigated the effects of directly manipulating selective attention for dysphoric stimuli on depressive symptoms. Mild to moderately depressed college students (N=34) were randomly assigned to complete 4 sessions of either attention training (AT) or no training (NT) during a two-week period. Participants completed self-reported assessments of depressive symptoms at baseline, post-training, and follow-up. Participants in the AT condition had a significantly greater decrease in depressive symptoms from baseline to follow-up than participants in the NT condition. This group difference was mediated by change in attention bias. Our findings suggest that biased attention may have a causal role in the maintenance of depressive symptoms.
