Telepsychology in the context of "Telephone counseling"

Telephone counseling (also known as telephone therapy, telephone-based or telephone-delivered psychological treatment) refers to the use of the telephone to deliver any type of psychological treatment or therapy (such as cognitive behavioral therapy) for mental health difficulties (like depression, anxiety). Telephone therapy can be as effective as traditional, face-to-face therapy. Along with online therapy, it is a type of telepsychology service. In telephone-based therapy, there is verbal communication, but no non-verbal communication which is present in video calls, for example.
