가족구조와 친구연결망이 청소년의 삶의 만족도에 미치는 효과 = Effects of Family Structure and Friendship Network on Korean Adolescents` Life Satisfaction

다국어 초록 (Multilingual Abstract)

Relationships in family and friendship are known to have important effects on adolescents`ife satisfaction. However, most of studies concerning those effects cannot but have an important limitation when they merely depend on respondents` subjective evaluation of those relationships rather than capturing the structure of the relationships. This paper aims to estimate the structural effect of adolescents` networks on life satisfaction, controlling for adolescents` attachment to interacting others, based on global friendship network data(N=356) collected at a highschool in 2008. First, this paper confirmed previous studies that adolescent`s attachments to both parents and friends are significantly related to higher level of life satisfaction. Second, for the structural effect, we found the disadvantage of first-born child and the positive effect of popularity (i.e., in-degree centrality) among classmates on life satisfaction, while single-parent family and expansiveness (i.e., out-degree centrality) in friendship networks did not show any significant effect. Third, the positive effect of parental attachment is stronger for students from single-parent family and that of popularity in friendship network stronger for first-born students. These structural effects call for future research on the specific mechanism from network structure to subjective well-being.
