Abstract
Addington J, Van Mastrigt S, Addington D. Duration of untreated psychosis: impact on 2-year outcome. Psychol Med 2004;34:277–84.[OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] Q Does the duration of untreated psychosis influence outcomes one year after initial treatment? ### ![Graphic][5]</img>Design: Prospective cohort study. ### ![Graphic][6]</img>Setting: Early Psychosis Program, Calgary, Canada; timeframe not stated. ### ![Graphic][7]</img>Population: 200 people (mean age 23 years), out of the 278 people admitted to the Calgary Early Psychosis Program, who completed the one year follow up assessment. Eligible participants had experienced their first episode of psychosis (DSM-IV criteria using Structured Clinical Interview), had significant positive symptoms (rated ⩾4 on Positive and Negative Syndrome Scale), and had received less than three months prior treatment. ### ![Graphic][8]</img>Prognostic factors: The duration of untreated psychosis was correlated with symptoms and social functioning on entering the programme and after one year. Whether or not the length of untreated psychosis independently predicted symptom outcome and quality … [1]: {openurl}?query=rft.jtitle%253DPsychological%2Bmedicine%26rft.stitle%253DPsychol%2BMed%26rft.aulast%253DAddington%26rft.auinit1%253DJ.%26rft.volume%253D34%26rft.issue%253D2%26rft.spage%253D277%26rft.epage%253D284%26rft.atitle%253DDuration%2Bof%2Buntreated%2Bpsychosis%253A%2Bimpact%2Bon%2B2-year%2Boutcome.%26rft_id%253Dinfo%253Adoi%252F10.1017%252FS0033291703001156%26rft_id%253Dinfo%253Apmid%252F14982133%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/external-ref?access_num=10.1017/S0033291703001156&link_type=DOI [3]: /lookup/external-ref?access_num=14982133&link_type=MED&atom=%2Febmental%2F7%2F4%2F101.atom [4]: /lookup/external-ref?access_num=000220290700009&link_type=ISI [5]: /embed/inline-graphic-1.gif [6]: /embed/inline-graphic-2.gif [7]: /embed/inline-graphic-3.gif [8]: /embed/inline-graphic-4.gif

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.
