Procrastination is a widespread phenomenon that has been associated with a host of cognitive, emotional, and motivational factors but about which a clear and integrated picture is still lacking. The aim of this study was to use primary established psychological procrastination-related factors in the literature to examine whether reliable subgroups of procrastinators can be identified through cluster analysis. To this end, 180 French-speaking students were asked to complete a measure of procrastination and four questionnaires assessing impulsivity, cognitive emotion regulation, self-esteem, and global motivation. Four clusters were identified: two with the lowest scores of procrastination (‘‘High regulated'' and ‘‘Regulated/low motivated''), one with higher scores of procrastination (‘‘Emotional''), and another with even higher scores (‘‘Unregulated''). The findings provide insights into the dynamic relationships between key procrastination-related factors and the mechanisms linked to the self-regulation difficulties that characterize trait procrastination. cop. 2014 Elsevier Ltd.
