摘要目的 考察青少年精神质、父母监控及同伴行为问题对外化行为问题的影响机制.方法 采用家长教养问卷、同伴问题行为自评问卷、Achenbach青少年自评量表、艾森克人格问卷,对全国7个城市的2 504名10～ 16岁青少年进行调查,用多元回归分析及SPSS Bootstrap法检验.结果 ①母亲监控、父亲监控、精神质、同伴行为问题及外化行为问题的得分分别为(4.02± 1.00)分、(3.49±1.19)分、(3.10±2.77)分、(1.25±0.27)分和(5.10±4.63)分;②父母监控水平高的青少年更少出现外化行为问题(β母亲=-1.240,』β父亲=-0.981,P＜0.05);③同伴行为问题部分中介了母亲监控和父亲监控与青少年外化行为问题的关系,中介效应占总效应的比例分别为25.0％和26.2％;④精神质调节了同伴行为问题的中介效应(系数乘积a1b3母亲=-0.016,a1 b3父亲=-0.014,P＜0.05),即精神质水平越高,父母监控通过同伴行为问题减少青少年外化行为问题的效应越强.结论 父母监控既直接影响也通过监管不良同伴交往间接影响青少年外化行为问题,青少年精神质在其中起调节作用.

abstractsObjective To explore the influence of parental monitoring,peer delinquency and psychoticism on externalizing problem in adolescents.Methods 2 504 adolescents aged 10-16 from 7 provinces in China participated in the surveys with externalizing problem,parental monitoring,peer delinquency and psychoticism were measured.The mediating effect of peer delinquency and the moderating effect of psychoticism were tested by stepped multiple linear regression and Bootstrap procedures.Results ①The scores of maternal monitoring,paternal monitoring,psychoticism,peer delinquency and externalizing problem were (4.02±1.00),(3.49±1.19),(3.10±2.77),(1.25±0.27) and (5.10±4.63) respectively;②Parental monitoring negatively predicted externalizing problem in adolescents(βmother =-1.240,βfather =--0.981,P＜0.05).③Peer delinquency played a partial mediating role in the relation between parental monitoring and externalizing problem,the percentages of mediating effect to total effect respectively were 25.0％ and 26.2％.④The mediation effect of peer delinquency was moderated by psychoticism (a1b3mother =-0.016,a1b3father =-0.014,P＜0.05).Conclusion Psychoticism moderated the mediation effect of peer delinquency in the relation between parental monitoring and externalizing problem in adolescents.
