There are many paradoxes existed between adult women's intergeneration relationships. The power structure between mother-in- laws/daughter-in-laws and the attachment relationship between mother/daughter are the sources of the paradox. Different perceptions of women in two generations would possibly bring in negative consequences. This study attempts to identify perception differences commonly found in adult women's intergeneration relationships. Factors related to the interpretation of those differences are also explored. In this study, 35 women in 12 families were interviewed individually. They were from different generations and varied in demographic backgrounds. Results indicated that perception discrepancies of women in different generations existed in three areas: boundary setting, responsibility of care, and parenting practice. Those differences would be managed under four circumstances: understanding the situation the other experienced, isolation or transcendence of self, the involvement of significant others, or experiencing crisis or transition in life.
