Background: This study was to identify the factors
influencing smartphone dependence among late school-
aged children, focusing on grit and family strengths.
Methods: A cross-sectional descriptive study was
conducted with 218 children in grades 5 and 6 who were re-
cruited from elementary schools in U and Y cities. The data
were collected through self-reported questionnaires,
including smartphone dependence, grit, family strengths and
general characteristics, for the month of December
2019, just before the novel coronavirus pandemic after
obtaining approval from IRB. The collected data were
analyzed using multiple regression.
Results: Smartphone usage time, the main purpose of
smartphone usage (game and social networking), and
grit were identified as significant factors of smartphone
dependence. This model explained 38% of the total var-
iance showing the variable of grit with the greatest variance.
Conclusions: A strategy to develop grit is needed to reduce
smartphone dependence among late school-age
children.
