Self-control is always crucial in many areas of life. Therefore, self-control failure is the source of many of the difficulties people face in their lives and also at the center of several problems, especially among adolescents. In this regard, the purpose of the study was to examine the mediating role of multi-screen addiction (MSA) in the relationship between self-control and procrastination among adolescents by using structural equation modeling (SEM). A cross-sectional design and an online questionnaire was used in this study. The study group composed of 390 adolescents studying at various high schools in Turkey. The results of correlation analysis showed that self-control was negatively correlated with MSA and procrastination. MSA also positively correlated with procrastination. Furthermore, the findings showed that MSA mediated the relationship between self-control and procrastination. The fit index of the SEM was found to be satisfactory. The results of the study were addressed in the context of the existing literature, and then suggestions were presented.
