Abstract
Background: The current article reports on the findings from a cross-sectional survey conducted among college students on a subjectively reported and objectively measured smartphone screen time (ST) and its relation to mental well-being.
Methods: We explored the magnitude of discrepancy between subjectively reported and objectively measured smartphone ST. Moreover, we assessed the interaction of mental well-being with personality traits among subjects with a discrepancy between the subjectively reported and objectively measured smartphone ST. The mental health of study participants was assessed using the WHO well-being index. Personality was assessed using the Big Five Inventory (BFI)- 10. A total of 202 students shared screenshots of the phone ST function and were included in the analysis.
Results: A total of 145 (71.8%) participants underestimated their daily smartphone ST, whereas 56 (27.7%) of them overestimated ST. In the regression analysis, the predicted odds of poor mental well-being were 1.43 times greater for subjects with higher neuroticism scores in the overall sample. Moreover, the predicted odds of poor mental well-being were 1.593 times greater for subjects with higher neuroticism scores among the study subjects who underestimated their ST.
Conclusions: The findings of the current study suggested that the magnitude of discrepancy between the subjectively estimated and objectively estimated ST varies across college students, with the discrepancy being significantly higher among those who overestimated their ST. The predicted odds of poor mental well-being were about one and a half times greater for subjects with higher neuroticism scores among college students who underestimated their ST.
