Review: psychoeducational interventions reduce depressive symptoms in cancer.

Study selection Scientific studies or systematic reviews of scientific studies (ie, qualitative or quantitative reviews that examined specific hypotheses, used a comprehensive search strategy, and stated explicit conclusions) were selected if they compared a psychoeducational intervention with usual care or an attentional control group, and some level of depression was the measured outcome; practice guidelines based on research were also included. Exclusion criteria included studies of children with cancer, spouses of patients with cancer, and interventions that were not strictly psychoeducational (eg, exercise).
