Abstract
Depression and anxiety are common in young people, yet many do not receive adequate support. Current guidelines recommend digital interventions as an effective approach; however, there is a need for more accessible, evidence-based programmes that are co-developed with young people and rigorously evaluated. The bilingual digital programme, MoodHwb, was co-designed with young people with depression and in collaboration with parents, carers, professionals and a digital media company. MoodHwb aims to support young people in managing their mood and well-being. An early evaluation study provided initial support for the programme theory and indicated its acceptability among users. The programme has since been refined based on feedback, and a feasibility randomised controlled trial has been completed.
