AS13-02 - Classification across the life course: recommendations of the ICD working group on mental and behavioural disorders in children and adolescents
Bibliographic record
Abstract
The divide between child and adult disorders disrupts the continuity of clinical care and is untenable in the face of evidence for continuity of psychopathology across ages. The ICD-11 Working Group on Classification of Mental and Behavioural Disorders in Children and Adolescents has set out to integrate the categories previously grouped as “Disorders with onset usually occurring in childhood and adolescence” in the main classification. The primary aim is to provide a classification that will facilitate efficient clinical care and will be easy to use for a range of medical and non-medical professionals across the World. The recommendations are based on literature reviews, group discussions and consultations with leading professionals. Clinical utility is the primary criterion. The principal proposals are: (1) A grouping of neurodevelopmental disorders will include autism, learning disorders, attention-deficit/hyperactivity disorder and other categories open to individuals irrespective of age; (2) Conduct disorder and Antisocial Personality disorder can be merged into a single category ‘Conduct/dissocial disorder’ diagnosed based on aggressive and deceptive behaviors in children and in adults; (3) Feeding and eating disorders can be merged into a single grouping with the same categories available to all age groups; (4) Categories that appear clinically useful but have insufficient evidence will be included in the main classification, but marked as ‘requiring further testing’; these may include disruptive mood dysregulation with dysphoria disorder, psychopathy, catatonia and avoidant-restrictive food intake disorder. The proposals are subject to further consultation and field testing.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
