RESULTS
A total of 30 studies with 5,159 patients met the inclusion criteria. Compared with control, the effect (standardized mean difference) at completion of treatment was −0.30 (95% CI, −0.48 to −0.13) for face-to-face cognitive behavioral therapy (CBT), −0.14 (−0.40 to 0.12) for face-to-face problem-solving therapy, −0.24 (−0.47 to −0.02) for face-to-face interpersonal psychotherapy, −0.28 (−0.44 to −0.12) for other face-to-face psychological interventions, −0.43 (−0.62 to −0.24) for remote therapist-led CBT, −0.56 (−1.57 to 0.45) for remote therapist-led problem-solving therapy, −0.40 (−0.69 to −0.11) for guided self-help CBT, and −0.27 (−0.44 to −0.10) for no or minimal contact CBT.
