This study identified constellations of childhood risk factors associated with violent criminal behavior in early adulthood. Police data were used to sample violent and nonviolent offenders from a population of young adult males with a history of juvenile probation. Risk factors were retrieved from their juvenile probation files. A single classification tree analysis organized these into a decision tree for violent criminal behavior with good predictive accuracy. Two constellations of risk factors were associated with a high risk of violent criminal behavior. The first consisted of juvenile delinquents who had been moderately involved with criminal peers, who had committed offenses under the influence of drugs, and who came from a dysfunctional family. The second was characterized by having been severely involved with criminal peers and having had criminal family members. Presenting with depressive symptoms in childhood was associated with a low risk of violent criminal behavior. These constellations bear clinical importance as they provide targets for personalized interventions.

与青少年暴力犯罪行为相关的青年犯罪因素的星座

这项研究确定了与成年初期暴力犯罪行为有关的儿童期危险因素的星座。警方的数据被用来对一群有少年缓刑历史的成年男性进行暴力和非暴力犯罪者抽样。从其青少年缓刑档案中检索到风险因素。单一的分类树分析将这些信息组织到暴力犯罪行为的决策树中，并具有良好的预测准确性。两个危险因素群与暴力犯罪行为的高危险性有关。首先是少年犯罪分子，他们与犯罪同伴有中等程度的关系，他们在毒品的影响下犯了罪，并且来自一个功能失调的家庭。第二个特点是与犯罪同伴严重交往，并有犯罪家庭成员。在儿童时期表现出抑郁症状与暴力犯罪行为的低风险有关。这些星座具有临床重要性，因为它们为个性化干预提供了目标。
