There are studies that point to the efficacy of online therapy, demonstrating that some clients can only appeal to psychotherapy that way, despite their manifest necessity.
Online psychotherapy is an offer of an alternative help made possible when traditional psychotherapy is not accessible, and it does not intend to replace the face-to-face relation. The goal is to reach people who need help and would not get that another way.
The online service lasts 50 minutes, just like the meeting at the medical office. The online service has the same ethical precepts of confidentiality and privacy as the ones in the face-to-face meeting. In order to use that tool, the person concerned need to have access to the internet via webcam.
