Abstract
Clarke GN, Hornbrook M, Lynch F, et al. A randomized trial of a group cognitive intervention for preventing depression in adolescent offspring of depressed parents. Arch Gen Psychiatry2001 Dec; 58 : 1127 –34 [OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] QUESTION: In adolescents with depressive symptoms and who have depressed parents, does a group cognitive intervention prevent or delay the onset of the subsequent development of a full depressive episode? Randomised {allocation concealed*}††, blinded {data collectors, data analysts, and study investigators}†,*, controlled trial with 24 months of follow up (median 14 months of follow up). Health maintenance organization (HMO) in Portland, Oregon, USA. 94 adolescents (mean age 15 y, 60% girls) with both subsyndromal depression and a parent with either a current episode of major depression or dysthymia, or an episode in the previous 12 months. 83% were followed for up to 24 months. 45 adolescents were allocated to usual HMO care plus a … [1]: {openurl}?query=rft.jtitle%253DArchives%2Bof%2BGeneral%2BPsychiatry%26rft.stitle%253DArch%2BGen%2BPsychiatry%26rft.aulast%253DClarke%26rft.auinit1%253DG.%2BN.%26rft.volume%253D58%26rft.issue%253D12%26rft.spage%253D1127%26rft.epage%253D1134%26rft.atitle%253DA%2BRandomized%2BTrial%2Bof%2Ba%2BGroup%2BCognitive%2BIntervention%2Bfor%2BPreventing%2BDepression%2Bin%2BAdolescent%2BOffspring%2Bof%2BDepressed%2BParents%26rft_id%253Dinfo%253Adoi%252F10.1001%252Farchpsyc.58.12.1127%26rft_id%253Dinfo%253Apmid%252F11735841%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=10.1001/archpsyc.58.12.1127&link_type=DOI [3]: /lookup/external-ref?access_num=11735841&link_type=MED&atom=%2Febmental%2F5%2F3%2F78.atom [4]: /lookup/external-ref?access_num=000172586000004&link_type=ISI

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.
