Abstract
(2002) American Journal of Psychiatry 159, 1044; Sigurdsson E, van Os J, Fombonne E. . Are impaired childhood motor skills a risk factor for adolescent anxiety? Results from the 1958 U.K Birth Cohort and the National Child Development Study. . June; . : . –6. . [OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] QUESTION: Do delayed childhood motor skills predict persistent anxiety in adolescence? Longitudinal cohort study. United Kingdom. 6850 people born during one week in March 1958 participating in an ongoing national birth cohort study. Data were collected when participants were 7, 11 and 16 years old. Motor impairment was measured using parental reports of the child’s not walking at 18 months of age and teacher reports of poor hand control at age 7; ‘clumsiness’ at age 7; poor hand control at 11 years, andpoor coordination at 11 years. Demographic information and emotional problems were controlled for. Maternally rated anxiety at 11 and 16 years. 8% of boys and 3% of girls had motor impairment. Boys with poor motor skills at age 7 had higher levels of … [1]: {openurl}?query=rft.jtitle%253DAmerican%2BJournal%2Bof%2BPsychiatry%26rft.stitle%253DAm.%2BJ.%2BPsychiatry%26rft.issn%253D0002-953X%26rft.aulast%253DSigurdsson%26rft.auinit1%253DE.%26rft.volume%253D159%26rft.issue%253D6%26rft.spage%253D1044%26rft.epage%253D1046%26rft.atitle%253DAre%2BImpaired%2BChildhood%2BMotor%2BSkills%2Ba%2BRisk%2BFactor%2Bfor%2BAdolescent%2BAnxiety%253F%2BResults%2BFrom%2Bthe%2B1958%2BU.K.%2BBirth%2BCohort%2Band%2Bthe%2BNational%2BChild%2BDevelopment%2BStudy%26rft_id%253Dinfo%253Adoi%252F10.1176%252Fappi.ajp.159.6.1044%26rft_id%253Dinfo%253Apmid%252F12042195%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=10.1176/appi.ajp.159.6.1044&link_type=DOI [3]: /lookup/external-ref?access_num=12042195&link_type=MED&atom=%2Febmental%2F6%2F1%2F18.atom [4]: /lookup/external-ref?access_num=000175951300023&link_type=ISI

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.
