Prevalence and Incidence of Nonsuicidal Self-Injury Among Federally Sentenced Women in Canada
Bibliographic record
Abstract
Nonsuicidal self-injury (NSSI) is a complex behavior that is not uncommon in the general population, yet little is known about the prevalence of this behavior among incarcerated women. Two studies were conducted to determine the prevalence and incidence of NSSI in federally sentenced Canadian women. In Study 1, a mixed-methods design that included a qualitative interview and a written questionnaire with a sample of 150 incarcerated women was used. In Study 2, archival data were analyzed for a random sample of 400 incarcerated women. Results indicated lifetime prevalence rates of NSSI ranging from 24% to 38%. Incidence of self-injury in a federal institution over a 1-year period was found to be 3.6 per 27.4 person-years (i.e., number of years incarcerated). Both studies indicated that for the majority of women in both samples, NSSI was first initiated in the community, prior to incarceration in a federal correctional institution.

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.
