The study investigated protective factors (school commitment/importance, parent/peer disapproval of antisocial behavior, positive future orientation, and religion) hypothesized to lower risk for antisocial behavior among adolescents who, as children, had been physically abused. Protective factors also were investigated for comparison, nonabused children, and for children at risk on abuse and other factors: low socioeconomic status and early antisocial behavior.
Analyses used a two-step hierarchical regression approach. In step 1, age, gender, and early antisocial behavior were entered as controls. In step 2, each protective factor was entered separately as a predictor. A final regression model in each case examined the additive (combined) effect of all protective factors on a given outcome. Tests of predictor-by-group interactions were used to examine group differences.
Among abused and nonabused children, having a strong commitment to school, having parents and peers who disapprove of antisocial behavior, and being involved in a religious community lowered rates of lifetime violence, delinquency, and status offenses. Having a positive future orientation appeared less powerful as a protective influence. Exposure to an increasing number of protective factors was for each outcome associated with a diminution in risk for antisocial behavior.
Protective factors represent targets for preventive intervention that are viable for children as they enter adolescence. The fact that protective factors were predictive of lower antisocial behavior in both the abuse and comparison groups suggests that protective effects are more universal than they are unique to a given group of children.
本研究调查了一些假设的保护因素(对学校的投入/重视程度、父母/同伴对反社会行为的不认可、积极的未来取向和宗教信仰),这些因素被认为可以降低童年时期遭受身体虐待的青少年出现反社会行为的风险。同时,也对这些保护因素在未受虐待儿童以及因虐待和其他因素(低社会经济地位和早期反社会行为)而处于风险中的儿童中进行了比较研究。
分析采用两步分层回归方法。第一步,将年龄、性别和早期反社会行为作为控制变量纳入。第二步,分别将每个保护因素作为预测变量纳入。每个案例的最终回归模型检验了所有保护因素对给定结果的累加(综合)效应。通过预测变量与组别的交互作用检验来考察组间差异。
在受虐待和未受虐待的儿童中,对学校有强烈的投入、有不认可反社会行为的父母和同伴以及参与宗教团体,都降低了终身暴力、犯罪和违规行为的发生率。积极的未来取向作为一种保护影响似乎作用较小。对于每种结果而言,接触越来越多的保护因素与反社会行为风险的降低相关。
保护因素是预防性干预的目标,对于进入青春期的儿童来说是可行的。保护因素在受虐待组和对照组中都能预测较低的反社会行为,这一事实表明保护作用比特定儿童群体所特有的作用更为普遍。
