The purpose of this study was to investigate the relationship between a daughter's cognition of her mother in adolescence and adulthood, and the factors that determined that relationship using longitudinal data. The participants were 20 female nursing students who were interviewed 11 years after they wrote their life histories. Several patterns in the participants' cognition of their mother in the 2 periods were identified on the basis of the following points: (a) the goodness-badness of their cognition of mother untill adolescence, and (b)the positivity- negativity of their cognition in adulthood. We analyzed typical cases in each pattern, and examined their features and contributing factors. The main factor found to affect the participants' cognition of their mother in adulthood was their cognition in adolescence: in the interview two-thirds of the participants stated still retained the cognition described in their life histories. On the other hand, some of the participants mentioned the positive aspects of their cognition of mother, even though they described problem in adolescence. Some told positively what they had described negatively, and some found out positive aspects keeping negative cognition. Besides their cognition of the goodness-badness in their life histories, the cognitive development and situational factors also effected changes in their cognition. This showed that the change could be attributed to both how serious the problems they described in their life histories were and to their degree of cognitive development and situational factors. We found that there was no relationship between the pattern of change and factors such as whether they were married or had children.
