Psychiatry is employing smartphone technology as an innovative tool in the assessment and treatment of schizophrenia and other serious mental illness. Prominent in this endeavor is Dror Ben-Zeev, an assistant professor of psychiatry at Dartmouth Medical School and director of the Thresholds-Dartmouth Research Center in Chicago. In a new study, Ben-Zeev and his colleagues evaluated a range of approaches, including the use of mobile phones to gather information about patients' symptoms, moods and medication use. The phones could then be used to deliver real-time, real-world interventions, such as prompts to take medication or engage in healthy behaviors like diet, exercise or stress-reducing activities. "We are using the technology that is already in your pocket to create a completely new medium for psychotherapeutic intervention," says Ben-Zeev. "You can have therapy with you and accessible to you whenever and wherever you have the need, potentially anywhere in the world."
