Objectives: The purpose of this study identified the perceived quality of parent-child relationships and attitudes toward filial duty contracts among young adult children. Also, this study is to examine the effects of sociodemographic characteristics and perceived quality parent-child relationships on the attitudes toward filial duty contracts and the requirement for filial duty contract details. Method: For this study, a survey was conducted with 210 college student children in young adulthood in Seoul and Gyeonggi-do. The questionnaire consisted of the ‘Attitudes toward Filial Duty Contracts Scale’, the ‘Requirement for Filial Duty Contract Details Scale’, and the ‘Quality of Parent-Child Relationships Scale’ with a demographic questionnaire. Specifically, the Attitudes toward Filial Duty Contracts Scale consisted of the support for contract, the intention of contract, and reservation contract amount on young adult children's mind. Data were analyzed by means of descriptive statistics and multiple regression analysis. Results: The major findings of this study are as follows: First, young adult children reported the relationship with mother better than father's and mid levels of support and intention of filial duty contract. They also showed that their reservation contract amount on their mind was about 500 million won. Second, the multiple regression analyses revealed that gender and pride of one's father positively related to their support for filial contract. Also, gender, the pride of one's father, and emotional closeness to one’s father significantly affected their intention of filial contract. In addition, among the variables, only monthly family income significantly predicted their reservation contract amount. Finally, the multiple regression analyses revealed that birth order and gender significantly predicted the normative duty contract. Also, the pride of one’s father significantly affected the emotional support contract. However, filial duty contract details such as caregiving for sick parents, physical support, and economic support have been found to be meaningless. Conclusions: The findings suggest that preparative education of aging for parents who are considering making the filial duty contracts with their children should include some realistic advice. These pieces of advice include their parent-child relationship and consideration of their own overall asset sizes.
