Influence of Smartphone Dependence, Mental Health, and Resilience on Military Life Adjustment Among Soldiers: A Cross-Sectional Study

Purpose: This study aimed to examine the influence of smartphone dependence, mental health, and resilience on military life adjustment among soldiers.Method: Data from a total of 173 subjects were collected from February 11, 2025 to March 8, 2025, using a self-report questionnaire. The data were analyzed using independent t-tests, one-way ANOVAs, the Scheffé test, Pearson’s correlation coefficient, and multiple linear regression analysis.Results: Resilience (β=.65, p<.001), high-risk smartphone dependence (β=-.17, p=.001), mental health (β=-.14, p=.027), and the experience of difficulties in military life (β=-.12, p=.001) were identified as factors influencing military life adjustment. These variables accounted for 83.0% (F=67.92, p<.001) of the variance in military life adjustment.Conclusion: The findings of this study demonstrate the necessity of developing integrated intervention programs to enhance military life adjustment among soldiers. In particular, as resilience was identified as the most influential factor, interventions aimed at strengthening resilience, along with strategies for regulating smartphone use, promoting mental health, and alleviating service-related stress, are warranted.
