Abstract

Abstract: Objectives: A recent report from the US Institute of Medicine indicated that identifying core elements of psychosocial interventions is a key step in successfully bringing evidence-based psychosocial interventions into clinical practice. Component studies have the best design to examine these core elements. Earlier reviews resulted in heterogeneous sets of studies and probably missed many studies.Methods: We conducted a comprehensive search of component studies on psychotherapies for adult depression and included 16 studies with 22 comparisons.Results: Fifteen components were examined of which four were examined in more than one comparison. The pooled difference between the full treatments and treatments with one component removed was g = 0.21 (95% CI: 0.03∼0.39). One study had sufficient statistical power to detect a small effect size and found that adding emotion regulation skills increased the effects of CBT. None of the other studies had enough power to detect an effect size smaller than g = 0.55. Only one study had low risk of bias.Conclusions: The currently available component studies do not have the statistical power nor the quality to draw any meaningful conclusion about key ingredients of psychotherapies for adult depression.
