Depression is a common health problem in adolescents. Negative attentional bias has been theorized to play a critical role in the onset and maintenance of depression, suggesting that reduction of such biases may treat symptoms of depression. Recent studies have shown that attention bias modification(ABM) training could reduce depressive symptoms in both dysphoria and previously depressed adult patients.To test the effectiveness of ABM training on the treatment of depressive symptoms in depressed adolescents, we designed a randomized, double-blind, placebo controlled trial in adolescents with major depressive disorder(MDD).
