父母婚姻冲突、不良同伴交往对初中生攻击行为的影响: 一个有调节的中介模型

摘要： 采用问卷法对1406名初一学生进行调查，考察了不良同伴交往在父母婚姻冲突与初中生攻击行为关系间的中介效应，以及冲动性对这一中介过程的调节效应。结果发现：（1）在控制了性别、年龄、家庭人均月收入和父母受教育水平之后，婚姻冲突显著正向预测青少年攻击行为；（2）不良同伴交往在婚姻冲突与攻击行为关系间起着显著的部分中介作用；（3）冲动性对中介路径“婚姻冲突 → 不良同伴交往→攻击行为”具有显著的调节效应。
Abstract: It is valuable to realize that a family not only is the most basic and vital units of the society, but also has a far–reaching influence on development of the individual. Under the psychological field of vision, the parental marital conflict is a key point which has effect the stability of family systems. Moreover, many empirical studies indicate that marital conflict is associated with adolescent aggressive behavior . At the same time, the peer is also increasingly important in determining adolescents academic, physical, and socio–emotional well–being. Based on the family systems theory, the present study investigated the mediating effect of deviant peer affiliation on the relationship between parental marital conflict and adolescent aggressive behavior, and impulsivity ’s moderation of the effect of peer context. Children’s Perception of Inter–parental Conflict Scale(CPIC), the Negative Urgency– Premeditation–Perseverance–Sensation seeking–Positive Urgency (UPPS–P) Scale, aggressive behavior questionnaire and deviant peer affiliation questionnaire were administered to 1406 adolescents (Mean age =12.90, male =699)from junior middle school in Guangdong province in southern China. Chi–square test and t test showed that there were no differences between students who lost to attrition gender, age and other variables in this study. The assessment was conducted in class. All materials and procedures were approved by the Ethics in Human Research Committee of author’s university. The results presented mean, standard deviations, and the bivariate correlations between the variables involved in this study. Path analyses were tested to use the bootstrapping method in the structural equation modeling software Mplus 7.1, with the full–information maximum likelihood estimation. Congruent with our hypothesis, the mediation model seems to perfectly fit the data: x2/df= 2.012, CFI= .99, RMSEA= .027. The bias–corrected bootstrapping result indicated that the indirect effect of parental marital conflict on adolescent aggressive behaviors through deviant peer affiliation was significant (standardized indirect effect = .02; 95% CI [ .001, .02]). As shown in results, consistent with the hypothesized pathway, when controlling for gender, age and family income, parental marital conflict was positively associated with adolescents deviant peer affiliation
