Figure 6 displays a forest plot of the standardized mean difference (SMD) of depression in adult psychotherapy trials (k=12), stratified by type of psychotherapy. The overall SMD was −0.37 (95% CI, −0.55 to −0.19). For cognitive behavior therapy trials (k=5), the SMD was −0.39 (95% CI, −0.70 to −0.08). For problem-solving therapy trials (k=3), the SMD was −0.26 (95% CI, −0.52 to 0.00). For dialectical behavior therapy trials (k=1), the SMD was −0.22 (95% CI, −0.64 to 0.20). For psychodynamic/interpersonal therapy trials (k=2), the SMD was −0.77 (95% CI, −1.32 to −0.22). For other nondirect therapy trials (k=1), the SMD was −0.18 (95% CI, −0.74 to 0.38).
