The 2005 British Columbia Smoking Cessation Mass Media Campaign and Short-term Changes in Smokers Attitudes
Bibliographic record
Abstract
The effect of the 2005 British Columbia (BC) smoking cessation mass media campaign on a panel (N = 1,341) of 20-30-year-old smokers' attitudes is evaluated. The 5-week campaign consisted of posters, television, and radio ads about the health benefits of cessation. Small impacts on the panel's attitudes toward the adverse impacts of smoking were found, with greater impacts found for those who had no plans to quit smoking at the initial interview. As smokers with no plans to quit increasingly recognized the adverse impacts of smoking, they also increasingly agreed that they use smoking as a coping mechanism. Smokers with plans to quit at the initial interview already were well aware of smoking's adverse impacts. Respondents recalling the campaign poster, which presented a healthy alternative to smoking, decreased their perception of smoking as a coping mechanism and devalued their attachment to smoking. Evidence was found that media ad recall mediates unobserved predictors of attitudes toward smoking.

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.
