Depression among childless middle-aged and elderly people is a serious social problem in Korea. However, few studies examine the influence of life satisfaction on the depression of spouses as actors and partners. Hence, this study analyzes the influence of life satisfaction (a positive factor childless married couples may have) on depression. This cross-sectional study employed data on couples to analyze the effect of life satisfaction on the depression of childless married couples as actors and partners via the actor-partner interdependence model. The Korea Longitudinal Study of Aging was employed to investigate life satisfaction and depression among 207 childless middle-aged and elderly couples. Regarding actor effects, wives' (β = -0.285, = 0.004) and husbands' (β = -0.403, < 0.001) life satisfaction significantly affected individual depression. Regarding partner effects, husbands' life satisfaction (β = -0.255, = 0.011) significantly affected wives' depression, and the wives' life satisfaction (β = -0.375, < 0.001) significantly affected husbands' depression. A childless actor's life satisfaction affected own and partner's depression. Thus, spouses should work together to improve their life satisfaction, thereby improving their depression.
韩国的中年和老年无子人群中存在严重的抑郁问题。然而，很少有研究关注配偶作为演员和伴侣的生活满意度对抑郁的影响。因此，本研究分析了生活满意度（无子已婚夫妇可能具有的积极因素）对抑郁的影响。本横断面研究采用夫妻数据，通过演员-伴侣相互依存模型分析了生活满意度对演员和伴侣无子已婚夫妇抑郁的影响。韩国老龄化纵向研究调查了 207 对无子的中年和老年夫妇的生活满意度和抑郁情况。关于演员效应，妻子（β=-0.285， = 0.004）和丈夫（β=-0.403， < 0.001）的生活满意度显著影响了个体的抑郁。关于伴侣效应，丈夫的生活满意度（β=-0.255， = 0.011）显著影响妻子的抑郁，妻子的生活满意度（β=-0.375， < 0.001）显著影响丈夫的抑郁。无子的演员的生活满意度会影响自己和伴侣的抑郁。因此，配偶应该共同努力提高生活满意度，从而改善抑郁状况。
