An Examination of the Effectiveness of Smoking Cessation Treatment Interventions for Individuals with Severe Mental Illness: A Pilot Randomized Controlled Trial
Bibliographic record
Abstract
To evaluate the effectiveness of two different smoking cessation interventions for individuals with severe mental illness. Study participants (N = 61) randomly assigned to the SC-R group (n = 29) were offered 24 weeks of no cost Nicotine Replacement Treatment (NRT); participants assigned to the SC + group (n = 32) were offered 24 weeks of no cost NRT plus two initial individual counselling sessions of motivational interviewing and weekly psychosocial group support for 24 weeks. At 6 months the smoking cessation outcome was 7% for the SC-R group and 14% for the SC + group, but there was no statistically significant difference between the groups. Both groups showed a significant decrease in the number of cigarettes smoked per day and significant improvement in physical health functioning. Clients with severe mental illness, high prevalence of co-occurring substance use and experience of homelessness, are both interested and able to quit smoking and reduce cigarette use.

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.
