The present study investigated spousal interdependencies in well-being and the sources of these interdependencies among Americans and Japanese. We collected high-powered three-wave longitudinal and cross-sectional data from a wide age range of participants (Ns = 3,012 American couples aged 26–96 and 2,307 Japanese couples aged 24–76) and assessed a variety of well-being measures. Study 1 replicated previous findings that American spouses’ well-being was positively associated with each other. Studies 2a and 2b generalized the findings of Study 1 to Japanese spouses. Both Studies 1 and 2b showed conflicting results: There were effects of mutual influence and shared environmental factors’ influences on American and Japanese spouses’ well-being in a longitudinal actor-partner interdependence model when using the cross-lagged panel model, but not when using the random intercept cross-lagged panel model. These findings illustrate that the interdependent nature of well-being is an essential feature of American and Japanese married couples.
米国人の縦断的夫婦データと日本人の横断的・縦断的夫婦データを用いて、幸福感が配偶者間で関連しているかどうかを検討しました。米国人・日本人ともに、先行研究に基づいた縦断データ分析（CLPM）を行うと同様の結果が得られた一方で、新たな縦断データ分析（RI-CLPM）を行うと異なる結果が得られたのが特徴です。
