中年期における子どもの有無と夫婦関係――主観的幸福感との関係から――

抄録

This study is aimed at examining the relations between parenthood and the marital relationship from a perspective of subjective well-being in middle-aged adults. An online survey was conducted with parents and non-parents from 45 to 60 years of age (N=558). Descriptive analysis suggested that both the frequency of actions as a couple and the degree of intimacy with one's spouse in non-parents were higher than in parents. Hierarchal multiple regression analysis and mediation analysis indicated that actions as a couple predicted higher levels of subjective well-being through the medium of intimacy with one's spouse in non-parents and fathers, while actions as a couple directly predicted higher levels of subjective well-being without the medium of spousal intimacy in mothers. The results mentioned above might reflect both the effects of actions as a couple on spousal intimacy and the specificity of middle-aged mothers.
