Meta-Analysis: Effectiveness of therapist-guided remote vs. in-person cognitive behavioral therapy

Study Design and Population: This systematic review and meta-analysis investigated the efficacy of therapist-guided remote cognitive behavioral therapy (CBT) compared to traditional in-person CBT. The authors conducted a comprehensive search across several databases, including MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials, up to July 4, 2023. A total of 54 randomized controlled trials (RCTs) were included, encompassing 5463 adult patients presenting with various clinical conditions. The study meticulously assessed the risk of bias and extracted data using a standardized approach, and outcomes were analyzed using a random-effects model.

Main Findings: The primary analysis focused on patient-important outcomes, comparing the effectiveness of remote and in-person CBT across diverse conditions such as anxiety and related disorders, depressive symptoms, insomnia, chronic pain or fatigue syndromes, body image or eating disorders, tinnitus, alcohol use disorder, and mood and anxiety disorders. The meta-analysis, based on moderate-certainty evidence, found little to no difference in effectiveness between remote and in-person CBT (standardized mean difference [SMD] −0.02, 95% confidence interval −0.12 to 0.07), suggesting that both delivery methods are comparably effective across a range of disorders.

Implications for Practice: The findings indicate that therapist-guided remote CBT is nearly as effective as in-person CBT for treating a variety of mental health and somatic disorders. This supports the potential for remote CBT to significantly increase access to evidence-based care, especially in settings where in-person therapy is not feasible or is limited by geographic, economic, or social barriers. Future research should explore optimizing remote CBT delivery methods to further enhance accessibility and efficacy.
