Predictive Factors of Violence in Prison

Overview

Prison concentrates people with violent behavior and patients suffering from psychiatric disorders. Aggression are daily, the suicide rate is 5 to 10 times higher than the ordinary environment and current prevention devices have shown their limits. That's why, in order to improve the violence's prevention in prison, the investigator propose to identify the predictive factors of violence by studying retrospectively the link between the psychiatric profile and commission of violence after being jailed.

From the 1st January to the 31 December 2012, every man incarcerated was screened thanks to the Mini International Neuropsychiatric Interview (MINI) to establish the presence of a current and/or past psychiatric diagnoses. In addition, collection of violent incidents based on penitentiary's reports (aggression, suicide, self-mutilation, intoxication, murder…) was conducted . Then statistic analysis compared psychiatric characteristics of prisoners according to whether they commit violence or not within 12 months after being jailed, distinguish the authors of self and hetero aggressive violence. Those tests are completed with a cluster analysis to precise psychiatric from criminological profiles of dangerousness.
