This research project aims to evaluate the feasibility and effectiveness of a new approach to tailored mobile applications using the Chorus Participatory Mobile Framework. PHP and IOP program participants—patients and therapists--will be consented and enrolled by study staff. Study participants will be invited to workgroups specific to their program to discuss the usability of Chorus and be asked to complete surveys on demographics, satisfaction, self-efficacy, and involvement with Chorus and usability of the tool.
