    The purpose of this study was to develop a Japanese version of the Pure Procrastination Scale (PPS-J), and examine its reliability and validity. The original version of the scale was developed to measure procrastination, a phenomenon that involves a voluntary delay of an intended course of action despite expecting to be worse off for doing so. In this study, a confirmatory factor analysis was conducted on 195 university students. The scale has a 12-item, three-factor structure consisting of “implemental procrastination,” “decisional procrastination,” and “untimeliness.” It was confirmed that it had sufficient internal consistency and construct validity. It was also shown to have acceptable retest reliability in a study of 57 university students. A daily life survey of 44 university students showed the substantial construct validity of the PPS-J. Overall, the results suggest that the PPS-J is a valid scale for measuring procrastination.

    This study aimed to examine the process of adaptation after the experience of regret, with a focus on regulatory focus as a factor determining regulation strategies for regret, cognitive emotion regulation as a regulation strategy for regret, and preparatory functions of regret. We evaluated a model in which regulatory focus influences cognitive emotion regulation and how it influences preparatory function through regret using a questionnaire survey administered to 430 university students. The results suggest that several processes lead to preparatory functions of regret. For example, there seems to be a process whereby “positive reappraisal,” promoted by promotion focus, reduces regret and enhances preparatory function, and another process whereby several maladaptive strategies promoted by prevention focus increase regret, which facilitates preparatory function. In addition, some maladaptive strategies are strengthened by promotion focus, and some adaptive strategies are associated with prevention focus and increased regret.
