Much like traditional therapy, it really all comes down to the client's determination and effort to take support from the therapist and apply it to their lives. 

CBT (cognitive behavioral therapy) can be applied and implemented into a session whether in person or over video. 

Seeking help and changing one's life is ultimately up to the end-user. There's no one that can do it for us.

A small 2014 study also found that teens who were counseled over the phone for obsessive compulsive disorder found just as much success in treatment as their peers who met therapists face-to-face. And more recently, researchers in South Carolina found that veterans who experience post-traumatic stress disorder respond just as well to therapy over videoconference to treatment received in office.

Journal of Telemedicine and Telecare, Susan E. Palsbo, Center for Health and Disability Research, 2007: This study was conducted to determine if telepractice was equivalent to in-person service delivery. Results show that "post-discharge therapy and evaluation using video conferencing are equivalent to face-to-face therapy and evaluation for post-stroke patients."
