Procrastination is defined as "the act of needlessly delaying tasks to the point of experiencing subjective discomfort"(Solomon and Rothblum, 1984). Although there have been many procrastination studies in Europe and United States, Japanese students have not been investigated in terms of their procrastination. This study examined the frequency of Japanese university students' procrastinatory behavior on academic tasks and its relation to depression and personality. The subjects were 143 male and 121 female undergraduate students enrolled in an introductory psychology class, who completed the Procrastination Assessment Scale for Students (PASS), a measure of academic procrastination, the Self-rating Depression Scale (SDS), and the Temperament and Character Inventory (TCI), a measure of four temperament and three character dimensions of Cloninger's personality theory. The results indicated that a high percentage of students procrastinated on several academic tasks. Academic procrastination was positively correlated with depression and novelty seeking, and negatively correlated with persistence and self-directedness.
