This study investigated the longitudinal relationships among self-concept, parenting behaviors, peer relationships by ACLM(Autoregressive Cross-Lagged Modeling) for early adolescents’students. For this analysis, metric invariance, configural invariance, and error covariance invariance assumptions were met. The data was Korean Education Longitudinal Study (KELS) collected by Korea Educational Development Institute (KEDI), for three years (1st year, 2013, elementary 5th), (2nd year, 2014, elementary 6 th) (3rd year, 2015, middle 1st).
The results showed that the self-concept, parenting behaviors, and the peer relationships had a significant autoregressive effect (p<.01) across three years in the group. But, the autoregressive effects for the self-concept and parenting behavior were larger than the peer relationships’ autoregressive effect. That is, the peer relationship is less stable than self - concept or parenting behavior, and therefore it is more likely to change over time.
The cross-lagged regressive effects showed that the self-concept is more influenced by the parenting behaviors than peer relationships. The parenting behaviors were also influenced by the self-concept, and these two variables were complementary causality that acted as cause and effect. In the relationship between the self - concept and the peer relationships, the self - concept only acted as a cause of the peer relationship.
