However, the potential adaptability of procrastination, largely considered as a maladaptive construct, and its possible developmental connection to perfectionism remains unclear. The purpose of this study was to examine the individual differences of the multidimensional models of both perfectionism and procrastination, as well as investigating potential links between the two constructs. Methods: A convenience sample of 206 undergraduate students participated in this study. Participants completed a questionnaire consisting of 236 questions regarding the variables under investigation. Results: The adaptive model of procrastination yielded largely insignificant results and demonstrated limited links with adaptive perfectionism, while maladaptive procrastination was consistently associated with maladaptive perfectionism, lending further evidence of a unidimensional model of
