Examining Depression Among Perpetrators of Intimate Partner Homicide
Bibliographic record
Abstract
Male depression has been recognized as an important factor in some cases of intimate partner violence but there is a paucity of literature connecting depression and intimate partner homicide (IPH). This retrospective study provides a preliminary analysis that distinguished depressed from nondepressed perpetrators of IPH from a sample of 135 cases analyzed by a coroner's homicide death review committee in Ontario, Canada. Depressed perpetrators were more likely to commit homicide-suicide and had almost 1.5 times the number of risk factors present than nondepressed perpetrators. Consistent with the existing literature, the results indicated that depressed perpetrators were significantly older, more likely to commit homicide-suicide than homicide only, more likely to have prior threats or attempts of suicide, more likely to have been abused or witnessed domestic violence as a child than nondepressed perpetrators and more likely to exhibit sexual jealousy. The implications for these findings are outlined in terms of training of mental health professionals and public awareness about the potential lethality of domestic violence.

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.
