Informing school sex education using the stages of change construct: sexual behaviour and attitudes towards sexual activity and condom use of children aged 13-16 in England
Bibliographic record
Abstract
A survey of 3820 school children in England aged 13-16 years examined sexual activity using the Transtheoretical Model (TTM) Stages of Change. A quarter (26%) of teens were sexually experienced, 44.8 per cent did not use contraception and 48.9 per cent did not use condoms, every time. Past history of condom and contraceptive use, and partner willingness to use condoms were the best predictors of being in Action or Maintenance stage for condom use. Of virgins, 19.82 per cent were in Contemplation or Preparation stages for intercourse, and 85.4 per cent would use condoms every time. Sex education should be tailored to Stage, and signposting to sexual health and contraception services. Copyright © 2007 SAGE Publications.

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.
