Development of the Academic Procrastination Behavior Scale for Yobiko Students and the Examination of its Reliability and Validity

Abstract

[Purpose]

  This study aimed to develop a scale that measures the degree of procrastination behavior of Yobiko students (or prep-school students) in completing their academic tasks and examine its validity and reliability.

[Methods]

  As a preliminary study, 295 students of a Yobiko in Tohoku region were surveyed. Based on their responses, 15 items were created to develop a procrastination behavior scale for Yobiko students (PBS-P). Then, 560 students were administered the PBS-P, and factor analysis was performed.

[Results & Discussion]

  Factor analysis of the scale identified two factors: “Delay in voluntary tasks” with 6 items and “Delay in deadline tasks” with 5 items. These factors had a high degree of consistency (α of .83 and .80, respectively). The results of this study confirmed the reliability (internal consistency) and validity (factorial and concurrent validity) of the “Academic Procrastination Behavior Scale for Yobiko Students.”

[Conclusion]

  This scale makes it possible to measure the academic procrastination behavior of Yobiko students and is considered to contribute to the planning of academic and school life support.
