 The study aims to provide a systematic review and narrative synthesis on whether digital health interventions, DHIs, improve parental outcomes such as mental health literacy, help seeking or uptake of services for children with mental health problems. The results show that there is no high quality evidence that DHIs can improve these outcomes and more research is needed to evaluate DHIs using rigorous study designs and consistent measures.
