약한 자기통제력과 부정적 양육방식이 청소년 비행에 미치는 상호작용효과

This study aimed to test the interaction effect between low self-control and poor parenting leading to juvenile delinquency, proposed by the biosocial perspective in criminology. It was further examined if the interaction varies on age, as is proposed by the interaction theory. Data from the 3rd, 5th, and 7th wave of the fourth graders panel of the Korean Children and Youth Panel Survey 2010(KCYPS 2010) were fitted into negative binomial regression models. Low self-control was found to be fairly consistent over the years and have strong effects on delinquency for all ages. Compared to the low self-control, poor parenting was less strongly correlated with delinquency, and its impact on delinquency was strongly significant only for sixth graders (3rd wave sample). The hypothesized interaction effect of low self-control and poor parenting was discovered only for sixth graders, but the direction was negative. It suggested either ‘the increasing effect of low self-control on delinquency becomes stronger as the parenting gets better’ or ‘the devastating impact of poor parenting on offense gets worse as the level of self-control increases.’ Therefore, poor parenting practices such as abuse and/or neglect are never to be administered to the adolescents who can adequately control themselves. Even to the juveniles with low self-control, any attempt of poor parenting appeared to be little effective in deterring their problem behaviors. Several suggestions for future research were proposed including, as an example, a test of bidirectional relationships among self-control, parenting, delinquent friend, and delinquency, etc.
