Paranoia involves the misattribution of threat to nonthreatening stimuli or situations, such as the false belief that a car is stalking you or that a friendly face is threatening. Paranoia can occur across psychopathology, including psychosis-spectrum disorders, mood disorders, and PTSD. Coping with Paranoia is a computer-based, cognitive-behavioral therapy program designed to teach skills to reduce distress associated with paranoia. The program is interactive, self-paced, and includes animated tutorials, exercises, and games intended to help teach cognitive-behavioral strategies to address symptoms of paranoia. I am currently evaluating the acceptability and feasibility of this novel treatment. This project is in collaboration with Jennifer Gottlieb at Boston University.
