Promoting an Evidence-Informed Approach to Addressing Problem Gambling in UK Prison Populations
Bibliographic record
Abstract
International studies find that between a quarter and a third of offenders may be defined as problem gamblers. No comparable studies have been conducted in the UK during the last decade, which has seen unprecedented changes in gambling legislation and opportunities. The present study in two English prisons (one male and one female) found that levels of problem gambling were in line with global estimates. 27.8% of men and 18.1% of women were rated as medium-risk and problem gamblers. Gambling problems were linked to current and previous offending for between 7% and 13% of all offenders.

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.
