Transition Mate: A Mobile Phone App to Support Self-Management and Transition in Young People with Chronic Illness

Moving from children's health services to adult health services is a stressful transition for young people with chronic illnesses like Type 1 diabetes, cystic fibrosis, or inflammatory bowel disease. During this changeover, young people often disengage from care, leading to worsening health. This study is testing a smartphone app called TransitionMate, designed to help young people manage their health independently and stay connected to adult care services during this critical period. Participants use the app for up to 18 months as they make the transition to adult services. The app supports self-management, provides reminders, and acts as a health companion during what can be a confusing and unsupported time. Researchers will track whether the app reduces emergency hospitalisations and helps young people stay engaged with their care. You may be eligible if you are aged 16 to 21, are a current patient of the Sydney Children's Hospital Network with a chronic illness, and are transitioning to adult services within the next 12 months. You must own a personal smartphone (iPhone or Android). Young people with intellectual disability affecting phone use, or whose primary diagnosis is a mental health disorder, are not eligible.
