Examining a Digital Health Approach for Advancing Schizophrenia Illness Self-management and Provider Engagement

Problem Statement: Among schizophrenia-spectrum populations, adherence to treatment is poor, community-based supports are limited, and efforts to foster illness self-management have had limited success. These challenges contribute to frequent, lengthy, and costly hospital readmissions and poor functional outcomes. Digital health strategies, in turn, hold considerable promise in the effort to address these problems. Across healthcare domains, digital health is a rapidly growing area due to its potential reach, accessibility, low cost, and implications for the use of data to customize treatments and identify risk trajectories. Despite this promise and for reasons that are not entirely clear, the development and study of digital health strategies for more severe mental health conditions such as schizophrenia is much less developed than other domains of healthcare. Objective: This feasibility trial will examine a digital health platform designed to enhance illness self-management and treatment engagement for individuals with schizophrenia. Technology: The investigators and collaborators have developed and piloted a digital technology called App4Independence (A4i). This platform was designed to (i) help prevent social isolation through behavioral activation prompts and peer-peer strategy sharing, (ii) enhance coping with schizophrenia symptoms through functions that draw on evidence-based strategies (e.g., texted tips derived from cognitive and behavioral therapies) and provide a novel technology that assists with the identification of auditory hallucinations, (iii) enhance treatment adherence through scheduling, text and reminder functions, (iv) track level of wellness/risk and progress on personal goals through both active (self-ratings) and passive (sleep monitoring proxy) metrics, and (v) facilitate communications with care providers through a provider dashboard summarizing platform-collected data gathered between appointments. Partners: This study builds on a partnership between the Centre for Addiction and Mental Health (research capability, mental health service and associated expertise, access to patient populations) and MEMOTEXT, a health technology company with a track record of success in digital health approaches across multiple health conditions and care contexts. Study Design: This single blind, randomized controlled trial examines the feasibility of A4i. Feasibility metrics include study recruitment and retention, rate of technology use, safety, and utility in clinical interactions. Other outcome metrics include symptomatology, treatment adherence, patient-provider alliance, and quality of life. In this trial, study participants will be randomized to either treatment or control conditions, with pre-post outcomes measured over a 6-month period. Implications: This research will provide critical information for the development of this new technology in the larger effort to address a key problem in the schizophrenia field - how to leverage technology to enhance illness self-management and care engagement in resource-limited service contexts. These findings will lay the groundwork for larger trials assessing the impacts of A4i on hospital readmission and functioning - providing essential evidence for commercialization and expanded access to this tool. This work is at the forefront of international efforts to explore and validate digital health approaches for schizophrenia.
