Adolescent-onset psychosis: prevalence, needs and service provision
Bibliographic record
Abstract
BACKGROUND: Little is known of the epidemiology and care needs of people with adolescent-onset psychosis. AIMS: To examine prevalence and the cross-sectional disability, needs and service provision for adolescent-onset psychosis in areas of central Scotland with a total population of 1.75 million. METHOD: We identified and contacted 103 young people using an opt-out research design. Fifty-three participants and their carers and keyworkers were interviewed using a modified version of the Cardinal Needs Schedule. RESULTS: The 3-year prevalence was 5.9 per 100,000 general population. Twenty-one (20%) adolescents were not in contact with mental health services; 80% of first admissions were to adult acute psychiatric wards. Those interviewed had high levels of morbidity: 29 (55%) had serious to pervasive impairment of functioning; there were relatively high levels of side-effects, negative symptoms, anxiety, occupational, friendship and family difficulties. Care provision was better for'clinical'than for'social'domains; 20% had five or more unmet needs; 17% had at least one intractable problem. CONCLUSIONS: This low-prevalence disorder requires an assertive multi-agency approach in the context of a national planning framework.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
