.80, p < .005), and small-sized effects in comparison to a passive (random g = .15, p < .005) or active treatment (random g = .13, p < .05). Also, larger effect sizes were found in studies of CBT combined with additional psychosocial treatment (random g = .31, p < .005) than for studies of CBT combined with pharmacotherapy (random g = .20, p < .05), or CBT alone (random g = .17, p < .05).
