Abstract
Academic procrastinatory behavior is defined as postponing the academic attainment against one’s wishes to do so and it is a serious problem for undergraduate students. To our knowledge, there has, however, been less attention paid to the relationship between academic procrastinatory behavior and self-identity. To elucidate a peculiar factor regarding academic procrastination during adolescence, 354 students who were enrolled at either a university educational department or a nursing professional school were asked to complete measurements of identity status and academic procrastination. Our results showed the following two points: (1) indices of present commitment and future commitment pursuit were significant predictors of students’ academic procrastination, but one of past crisis was not; (2) it suggested that a previous finding(Shanahan & Pychyl,2007) which the need to delay academic tasks until the late moment was alleviated as a function of ego identity status maturity was not necessarily supported. Theoretical and educational implications of these findings and also prospective studies were discussed.
