Predicting Predatory Behavior in a Population of Incarcerated Young Offenders

Abstract

Predatory relationships are characterized by violence or threats of violence and their prediction and prevention are matters of critical importance within the custodial setting. In an attempt to predict predatory behavior, 251 consecutive admissions to a secure custody Young Offenders Unit in a maximum security detention centre were administered the Young Offender-Level of Service Inventory (YO-LSI). Subjects ranged in age from 16 to 19 years. Twenty-eight of them subsequently displayed aggressive behavior toward other residents and had to be isolated. The YO-LSI distinguished predators from nonpredators and showed satisfactory interobserver reliability and internal consistency. Results suggested that predators have more extensive criminal histories and criminal sentiments, as well as more substance abuse, educational/employment, family, peer, and psychological problems.
