Mental health apps that serve as supplements to ongoing therapy have been developed for mobile devices. Here are some examples of currently available apps:
Mobile Therapy provides patients with a mood map which appears on their cell phones randomly throughout the day. When the map pops up the patient places a dot on the map to represent how they're feeling. Later the therapist can print out and chart the patient's moods. The app also offers exercises and techniques based on the patient's responses.
This app has been beta tested and a journal article written on the results of the research.
Another app addresses the problem of getting teenagers to do CBT homework. They aren't too enthusiastic about written work but doing homework on their mobile devices is a different story.
Two other apps help patients with severe depression and schizophrenia by prompting them with techniques and homework.
The full article and radio show from NPR more fully describes these apps.
