The purpose of this study is to evaluate the feasibility and effectiveness of their ongoing use of the Chorus Participatory Mobile Framework to support clinical care. Chorus is a framework and web application that allows users to rapidly create a broad range of automated text messaging (SMS), interactive voice (IVR), or mobile web applications using a simple and accessible visual interface without requiring any server programming. There will be two broad populations using Chorus: (1) programs (e.g. OCD Intensive Treatment Program) in which all participants will receive participatory mobile messaging and (2) programs (e.g. Adult Acute PHP) in which patients will be randomized to receive either participatory mobile messaging or no mobile messaging. Across all programs, Kandace Whiting and Armen Arevian will train PHP and IOP therapists starting with creating simple, basic, useful messaging content in Chorus to support patients in achieving program goals. Examples of messages include Cognitive Behavioral Therapy (CBT), symptom management, and stress management cues to patients in the Obsessive Compulsive Disorder Clinic, patients in the Adult Eating Disorder Clinic, and parents from The Achievement, Behavior, Cognition (ABC) Child Programs.
