Research has revealed that problematic smartphone use is a cause of procrastination. This study investigated the predictive role of problematic smartphone use on procrastination with consideration of the mediating effect of psychological flexibility. The moderating role of gender in the frequency of checking smartphones was also tested in this mediational model. Of total, 471 undergraduate students (369 female, 102 male) with a mean age of 20.65 participated in the study. The study was conducted face to face in classroom settings, and the results of the analysis revealed that psychological flexibility indeed affected the relationship between problematic smart phone use and procrastination. In addition, moderated mediation analysis suggested that female university students were significantly impacted. Finally, it was observed that psychological flexibility played a significant role amongst the female university students surveyed in the relationship between problematic smart phone use and procrastination.
