The aim of the research is to understand and compare the values related to marriage, childbearing and parenting between two generations of mothers and daughters in urban centers of Ilam County. The research method was cross-sectional survey, and data were collected by a researcher-made questionnaire. The cluster sampling method was conducted to gather data of 350 women aged 15 to 30 who have never married, and women aged 35 to 65 who have been married at least once. The findings show that the greatest generational difference are related to the attitudes towards marriage (traditional-modern), relationships outside marriage, childbearing, the appropriate number of children and criteria of spouse selection. In these fields, modern values are more prevalent in the attitudes of daughters compared to those of their mothers. There is consensus between both generations on the necessity of marriage, attitudes towards divorce, the suitable marriage age for girls and boys, the age gap between girls and boys for marriage, parenting, opposition to polygamy and the appropriate marriage time for girls. The findings indicate that the alignment and consensus of the two generations in a significant number of attitudes and differences in other dimensions have caused the generational difference to be more prominent than the generational gap or conflict in this research. Increasing family resilience, fostering intergenerational dialogue in the family, accepting intergenerational differences in the family as a life process in the modern era, and reducing traditional parental authority can prevent intergenerational differences from turning into intergenerational conflicts.
