RT Article T1 External Trigger Factors for Violent Offending: Findings From the U.K. Prisoner Cohort Study JF Criminal justice and behavior VO 44 IS 11 SP 1389 OP 1412 A1 Freestone, Mark C. A2 Ullrich, Simone 1973- A2 Coid, Jeremy LA English YR 2017 UL https://krimdok.uni-tuebingen.de/Record/1701019124 AB The role of “triggers” for violence is seldom considered when assessing risk of violence in prisoners and forensic patients. A sample of 494 cases from a two-phase study of violent prisoners in England and Wales were rated for presence of acute risk factors and “triggers” occurring before the index offense. Logistic regression was performed to test prediction of acute factors and triggers by preoffense static and stable dynamic factors. Regression models were then built to investigate associations between triggers and violent reoffending post release. Although stable dynamic risk factors were accurately predicted by static actuarial risk, neither were associated with specific violence triggers. An argument with a stranger resulting in violence was associated with future violent reoffending. Violence triggers are highly context-specific but cannot be predicted using existing risk factors. They have a complex relationship with preexisting dynamic factors resulting in future violence. K1 Violence K1 Offending K1 Trigger K1 Risk K1 Acute K1 Prisoner DO 10.1177/0093854817713237
