What Research Shows

A major meta-analysis by Barak et al. (2008) in the Journal of Technology in Human Services examined 92 studies and found that online therapy is equally effective as in-person therapy for many mental disorders, including depression and anxiety disorders.

The study by Carlbring et al. (2018) in the Journal of Affective Disorders confirmed these findings: internet-based CBT (Cognitive Behavioral Therapy) showed effect sizes comparable to face-to-face for depression, social phobia, and generalized anxiety.

Who Benefits Most

Ideal for:

People with mild to moderate depression or anxiety, those living in remote areas, individuals with mobility issues, and those who would avoid in-person therapy due to stigma.

Less suitable for:

People in acute crisis, with severe personality disorders, active suicidal ideation, or psychotic episodes. These cases require face-to-face intervention.

Online therapy doesn't replace in-person therapy — it complements it. And for millions of people who otherwise wouldn't seek help, it's the gateway.

The best therapy is the one you actually do. If the online format gets you started, that's enough.
