Editorial: 'Have you seen me lately' - Revisiting our understanding of significant mental health disorders for children and adolescents.

This editorial introduces the Journal's 2026 Annual Research Review (ARR). Three themes emerged in this year's ARR. The first revisits and expands our understanding of four longstanding mental health disorders - non-fatal self-harm, early conduct problems, eating, disorders and developmental language disorders. A second theme focuses on intervention development and efficacy by reviewing research on modifying school climates and behavioural treatments to address young children's exposure to trauma. A final paper provides a systematic review of meta-analyses on the predictive validity of caregiver sensitivity. Cumulatively, this set of review papers provides important updates on a wide range of prevalent and meaningful disorders, expanding our understanding of aetiology, developmental course, and in many cases, success (or lack thereof) to assess and treat these conditions.
