The immediate objective of this project was to demonstrate the feasibility of Remote Exercises for Learning Anger and Excitation Management (RELAX). The application is a remote, technology- enabled, anger treatment and management system based on current evidence-based CBT interventions. The project's objective was to show that RELAX (1) enables the practice of anger management strategies remotely through mobile phone interfaces; (2) integrates with evidence-based treatments through the implementation of an existing CBT anger management course; (3) provides information, direction, and feedback through physiological sensors and signal analysis; and (4) supports communication and direction by the therapist through a web-based therapist interface.
