The purpose of the study is to conduct a meta-analysis of the relationship between peer attachment and adjustment-related variables of adolescents. This study covers masters’ theses, doctoral dissertations, and journals published in Korea for the past nine years from 2010 to 2018. The final study consisted of 293 papers, made up of 157 master s theses, 12 doctoral dissertations, and 124 journals. The coding of data classified the data by study type, school level, and individual adjustment type with criteria suggested by Lipsy and Wilson (2001), and by Cooper (2010). The effect size was calculated by Fisher s Z score and was converted to a correlation for ease of interpretation. The overall effect size and effect sizes by moderator variables were all analyzed in terms of the random effect model. The results showed that positive peer attachment and positive adjustment had medium effect size, whereas positive peer attachment and negative adjustment, negative peer attachment and positive adjustment, and negative peer attachment and negative adjustment had small effect size. As a result of examining the magnitudes of the effects by study type, school level, and adjustment type, there were significant differences in the effect sizes of positive peer attachment and positive adjustment, positive peer attachment and negative adjustment, and negative peer attachment and positive adjustment. However, there were only significant differences in the effect sizes of negative peer attachment and negative adjustment according to school level. Based on these results, we discuss the relevance with prior study, present an interpretation of the results, and discuss the significance of the outcomes.
