The purpose of this study is to demonstrate empirically the moderating effects of parental relationships in the relationship between neighborhood disorder and depression. Neighborhood disorder is a problem to be solved for social progress in that it causes socioeconomic inequality and adversely affects mental health. Therefore, this study emphasizes the importance of parent attachment in mitigating the negative effects of depression in neighborhood disorder. we used data from the 6th year of the “Korean Youth Panel” for the second year middle school students. The results of the analysis were as follows: First, neighborhood disorder had a negative effect on depression. Second, parental attachment had a negative effect on parental attachment among social and psychological factors. But not significant. Third, the results of this analysis maintained statistical significance even under the control of socio-economic variables. Finally, only parent attachment showed a moderating effect on the relationship between the neighborhood disorder and the depression. In other words, it is confirmed that when the parental attachment level is high, the size of depression can be offset in the process of the community disorder having a static effect on depression. Therefore, in this study, the results of empirical verification show that parental attachment plays an important social support role in affecting depression in neighborhood disorder.
