The purpose of this study was to find out the impact of unmarried men and women s ego-state and life position toward life on their emotional, normative, and functional intentions for marriage. As a way of doing this, an online survey of 570 unmarried men and women in their 20s and 40s across the country was conducted, and 549 people were analyzed, excluding insincere responses. The results of the study were as follows. firstly, there were significant differences in emotional and monthly marriage intentions in relation to demographic and sociological variables, and significant differences in party and functional marriage intentions in terms of gender, final education, occupation, age, and average monthly income. Secondly, among the changes in the ego-state of unmarried men and women, controlled parents and nurturing parents affected the intention of emotional, normative and functional marriage. Thirdly, self-positive among unmarried men and women s life position toward life affected emotional, normative, and functional intentions of marriage, and self-denial, which is also a variable in life, affected emotional intent of marriage. The implication of this study is that it can provide basic information on national policy measures related to low birth rates and marriage, and provide ways to promote marriage intentions from transactional analysis perspective. Further study needs to explore the main variable of transactional analysis and marriage intentions, taking into account more diverse demographic and social variables.
