Summary: One hundred and sixty subjects who took the EPPS in 1963 when they were in the university were given the same test again recently. The two sets of scores they obtained on the two occusions were compared with each other. Significant differences were found on many of the EPPS scales. The group showed greater needs on Ach., Ord., Ant., Dom., Het., and Agg, than they did thirteen years ago while their needs on Aff., Int., Suc., and Aba. showed decreases. Men and women showed a similar trend of need change but they differed in the magnitude of the changes. It seemed that these need changes did not have much relation with the general social change of the community, but were rather a result of personal development of the subjects. It was also found that the need changes could be described in terms of the EPPS factors extracted in a previous study.
