The purpose of this study was to examine whether adult attachment mediates the relationship between family health and married women's marriage satisfaction, and to verify whether spouse support regulates the mediating effect of adult attachment. Therefore, in order to collect data on these variables, data were collected using an online survey method for 213 married women across the country. As a result of the study, first, the results of analyzing the relationship between family health, adult attachment, marriage satisfaction, and spouse support all showed significant correlations. Second, as a result of verifying the mediating effect of adult attachment, the mediating effect of adult attachment was confirmed in the relationship between family health and marriage satisfaction. Third, it was confirmed that the moderating effect of spouse support in the relationship between adult attachment and marriage satisfaction was significant as a result of confirming whether spouse support regulates the relationship between adult attachment and marriage satisfaction. Fourth, as a result of confirming the controlled mediating effect of spouse support, it was verified that the effect of family health on marriage satisfaction through adult attachment was controlled by spouse support. Based on this, the significance and limitations of this study and the suggestions of subsequent studies were discussed.
