Researchers from the University of Zurich compared treatment outcomes of an Internet-based intervention with a face-to- face intervention for depression. For that purpose, they divided a group of 62 participants suffering from depression into two groups. The number of sessions and the content of each session were identical for both interventions. Results showed that the Internet-based intervention was just as effective as a face-to- face intervention. Also, a 3-month follow-up revealed that participants who received “online therapy” were actually more stable than the ones who benefited from face-to- face interventions.

Data from a total of 40 randomized controlled trials was compiled into one systematic review by a group of Swedish researchers. The purpose was to evaluate the safety, efficacy, and cost- effectiveness of online therapy. It appears that I-CBT (internet-delivered cognitive behavioral therapy) is a viable option for children, adolescents, and adults who are struggling with mood and anxiety disorders. Compared to face-to- face interventions, I-CBT proves to be a safe, efficient and cost-effective alternative.

Researchers divided a sample of 69 participants into two groups: guided online intervention and live group treatment. The aim of the study was to assess the long-term effects of online therapy. Results indicated that that online therapy is at least as effective as group therapy and the effects are visible up to 3 years after treatment.

One of the largest studies on the effectiveness of “eHealth” was conducted with the help of U.S. Veterans Affairs. Within a four-year period, the number of psychiatric admissions of patients who received remote clinical videoconferences decreased by 24%. Also, the participants’ total days of hospitalization dropped by a significant 26%, for both men and women. As a conclusion, people who receive a mix of online therapy and hospital care will spend roughly 25% less time in the hospital, which translates to fewer expenses.

Another systematic review on the effectiveness of online therapy revealed that there are factors outside online therapy that can significantly influence the outcome of this intervention. In other words, client engagement and realistic expectations can positively impact the outcome of online interventions. Also, when it comes to online therapy, age and other demographics don’t seem to play a significant role.

“The use of eHealth has shown promising results in various mental health treatments, especially when guidance from a care provider is included. eHealth also provides opportunities for self-management and continuity of care. This combination of advantages of online and offline guidance and treatment render positive outcomes, making it a good alternative to regular face-to-face treatment.”
