Abstract
A moderate positive association has consistently been observed between psychosis and violence in existing literature. However, substantial variation is present across individual studies, and there is preliminary support for negative affect (i.e., anger, hostility, anxiety) as a causal link between these two constructs to explain the heterogeneity of results. Due to the limited scope of previous reviews and relevant studies published since, a systematic review of 35 empirical studies ( N = 15,597) was conducted to examine if, across existing literature that includes all three constructs, negative affect may correlate or mediate the preestablished relationship between psychosis diagnosis and/or symptoms and violence. Anger or hostility was positively associated with violence or physical aggression for individuals with a diagnosis and/or symptoms of psychosis in 31 (89 %) of the studies, of which seven were cross-sectional, nine were retrospectively predictive, and 19 were prospective. Anger which followed positive psychosis symptoms played a positive statistically mediating role in participants' subsequent violence in all six studies that investigated this pathway. Within studies that examined other forms of negative affect (anxiety, depression, fear), nine discovered positive association with violence, six found negative association, and seven demonstrated no association. These results align with theoretical models of violence in individuals with psychosis, suggesting that psychosis is a sometimes necessary but often insufficient risk factor for violence. When assessing violence risk for individuals with psychosis, negative affect may be critical to consider alongside symptoms in case formulation and to target in subsequent intervention efforts, as opposed to symptoms in isolation.

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.
