This study was to explore the roles, feelings and adaptive processes of four Taiwan daughters-in-law in the traditional funerals for their fathers-in-law or mothers-in-law. In-depth interview based on qualitative research was used to collect the data for the purposes of the study. By transcribing, coding, inducting and analyzing the data, the findings of the study were as follows: 1.The roles of daughters-in-law were the opinion-supporters, but not the decision-makers; were the executers and monitors in the funerals; and the assistances and feeling-supporters for their husbands. 2.Only one of the subjects was intellectual and rational in the funeral for her mother-in-law. The others, on the contrary, might feel sad, regret, busy, upset, panic, fear or worried in the funerals. 3.The common phenomenal in the adaptive processes of four subjects was to suppression their feelings in the funerals. Even though the funerals were finished, they still felt fear, guilty or sad. Suggestions for the death education, the attitudes and service quality of the agents for funerals, grief counseling and future studies were discussed in the end of the study.
