The Effect of Social Support and Self-Efficacy on Academic Procrastination with Smartphone Addiction as an Intervening Variable in Completing Final Students' Assignments

Abstract

This study aims to analyze the effect of social support and self-efficacy on academic procrastination with smartphone addiction as an intervening variable in final year students of the Faculty of Accounting, Pamulang University. This study uses a quantitative approach with a survey method. A total of 124 final year students were selected as respondents through a purposive sampling technique. Data were collected using a psychological scale to measure academic procrastination, smartphone addiction, social support, and self-efficacy. Data analysis was performed using the SmartPLS program. The results showed that social support did not have a significant effect on academic procrastination (p> 0.05), but had a negative and significant effect on smartphone addiction (p <0.01). Smartphone addiction was proven to have a positive and significant effect on academic procrastination (p <0.05). Self-efficacy did not have a significant effect on academic procrastination (p> 0.05), but had a positive and significant effect on smartphone addiction (p <0.01). Furthermore, the results of this study also prove that smartphone addiction significantly mediates the influence of social support (p < 0.05) and self-efficacy (p < 0.01) on academic procrastination. This study provides theoretical and practical implications in understanding the role of smartphone addiction as a mechanism that connects social support and self-efficacy with academic procrastination behavior in final year students.
