In this Editorial, we are pleased to introduce the 26 papers included in the 2026 Special Issue of\n                    <jats:italic>JCPP Advances<\/jats:italic>\n                    . This Special Issue aimed to advance our understanding of transdiagnostic mechanisms, dimensions, and practices in child and adolescent mental health, and includes original articles, reviews, commentaries, and an editorial perspective. Collectively, these articles illustrate three main \u2018transdiagnostic\u2019 conceptualisations; (i) mechanistic approaches identifying shared biological, cognitive, or affective processes across diagnostic boundaries; (ii) dimensional approaches mapping symptom covariance onto hierarchical structures such as the general \u2018\n                    <jats:italic>p<\/jats:italic>\n                    \u2019 factor and internalising, externalising, and neurodevelopmental spectra; and (iii) developmental, clinical\u2010staging approaches treating early, non\u2010specific features as precursors to a broad range of later\u00a0outcomes. Methodologically, the current Special Issue highlights both the opportunities and limitations of large existing datasets, multi\u2010informant assessment, and neuroimaging and genomic approaches, while underscoring the persistent difficulty of modelling transdiagnostic dimensions developmentally. Importantly, while translation into routine clinical care remains limited, the field is now well\u00a0positioned to test the clinical utility and effectiveness of transdiagnostic dimensional assessments and interventions in routine care.\n
