COVID-19 public health proscriptions have created severe if temporary, barriers to accessing face-to-face psychotherapy across the world. As disruptive as these are, they come on top of more long-standing barriers to getting psychotherapy faced by millions in need. eHealth interventions offer an avenue for redressing both types of barriers, but evidence about their efficacy remains a concern. This review of reviews and metaanalyses outlines the strength of evidence and effect sizes for guided and unguided approaches to eHealth interventions targeting common problems in psychotherapy (i.e., depression, anxiety, substance abuse, and general well-being). After a comprehensive search, a total of 65 reviews and meta-analyses were identified and evaluated for treatment effects, moderators, acceptability, and attrition. Findings show eHealth is acceptable and effective at improving depression, anxiety, alcohol-related problems, and general mental health compared to waitlist, and can even offer benefit as an adjunct to traditional psychotherapy. Mixed evidence was found when comparing guided versus unguided interventions as well as the strength of benefit relative to active controls and the degree to which these approaches are associated with attrition. eHealth interventions have the potential to be an effective tool for redressing both new and old psychotherapy access barriers.
