The CDC recently organized a panel to examine whether a series of constructs consistently acted as risk and/or direct protective factors for youth violence across four longitudinal studies. Analyses first examined constructs commonly assessed across all four studies and then included constructs unique to each study.
This paper describes findings from the Pittsburgh Youth Study (PYS) as part of this supplement to the American Journal of Preventive Medicine documenting the findings from the project.
Participants were boys in the youngest cohort of the PYS (N=503), which was initiated in 1987-1988. Constructs measured at age 12 years were trichotomized to test whether they acted as risk and/or direct protective factors in predicting violence (i.e., assault, rape, robbery) across ages 13-14 years and 15-18 years.
Multivariate logistic regressions with predictors present across studies indicated that depressed mood (OR=1.96) and low religious observance (OR=1.88) were risk factors for violence at ages 13-14 years, whereas peer delinquency acted as both a risk (OR=2.34) and direct protective factor (OR=0.44). Low peer delinquency was also a direct protective factor (OR=0.41) for violence at ages 15-18 years. Analyses including predictors specific to the PYS indicated that negative attitude toward delinquency (OR=0.50) was protective against violence at ages 13-14 years, whereas the risk factors of low perceived likelihood of being caught (OR=1.81) and high neighborhood disorder/crime (OR=1.77) predicted violence at ages 15-18 years.
Some factors may be best conceptualized as direct protective factors for nonviolence, whereas other constructs act primarily as risk factors that increase the probability of adolescent violence.
疾病预防控制中心最近组织了一个小组,以检查四个纵向研究中一系列结构是否一致地充当青年暴力的风险和/或直接保护因素。分析首先检查了所有四项研究中共同评估的结构,然后包括了每项研究特有的结构。
本文描述了匹兹堡青年研究(PYS)的结果,作为美国预防医学杂志增刊的一部分,记录了该项目的结果。
参与者是 PYS 中最年轻队列的男孩(N=503),该队列于 1987-1988 年启动。在 12 岁时测量的结构被三进制化,以测试它们是否在预测 13-14 岁和 15-18 岁之间的暴力行为(即攻击、强奸、抢劫)中充当风险和/或直接保护因素。
具有跨研究存在的预测因子的多元逻辑回归表明,情绪低落(OR=1.96)和低宗教信仰(OR=1.88)是 13-14 岁时暴力的风险因素,而同伴犯罪行为则是风险(OR=2.34)和直接保护因素(OR=0.44)。低同伴犯罪行为也是 15-18 岁时暴力的直接保护因素(OR=0.41)。包括 PYS 特定预测因子的分析表明,对犯罪的消极态度(OR=0.50)对 13-14 岁时的暴力具有保护作用,而低被抓获可能性的风险因素(OR=1.81)和高邻里紊乱/犯罪(OR=1.77)则预测了 15-18 岁时的暴力行为。
一些因素可能最好被概念化为非暴力的直接保护因素,而其他结构主要作为增加青少年暴力可能性的风险因素。
