Efficacy of Interpretation Bias Modification in Depressed Adolescents and Young Adults.

This study evaluated the efficacy of a four-session Cognitive Bias Modification-Interpretation program for 45 depressed adolescents and young adults (14-21 years old; 12 males, 33 females; Beck Depressive Inventory, Second Edition ≥ 14) randomized to an active intervention condition (repeated exposure to positive outcomes of depression-relevant ambiguous scenarios; n=23) or a control condition (n=22). Both conditions experienced reductions on a Test of Interpretation Bias at post-treatment, with no significant between-group differences. When limited to those with negative bias at baseline, the intervention group showed greater improvement in interpretation bias at mid- and post-treatment. In addition, the intervention group overall had greater improvements in self-reported negative cognitions than the control group at post-intervention and two-week follow-up. However, there were no differences between groups in depression or anxiety symptom change. Potential factors contributing to mixed findings are discussed.
