Abstract

Background: Problematic smartphone use may threaten student well-being, especially among nursing students who rely on smartphones for academic and clinical activities. This study estimated potential problematic smartphone use among Greek nursing students, examined its association with quality of life (QoL), and explored whether contextual factors modified these associations. Methods: A cross-sectional study was conducted among 331 nursing students in Greece from September to November 2025. Participants completed an anonymous online questionnaire including sociodemographic data, the Smartphone Addiction Scale–Short Version (SAS-SV), and the World Health Organization Quality of Life–BREF (WHOQOL-BREF). Results: The mean SAS-SV score was 29.30 ± 9.69, and 18.9% of students screened positive for potential problematic smartphone use. Mean overall QoL and general health satisfaction were 3.80 ± 0.78 and 3.97 ± 0.88, respectively. Higher SAS-SV scores were associated with lower physical, psychological, and environmental QoL, but not with social QoL. Years of study moderated only the association with environmental QoL. Conclusions: Problematic smartphone use was associated with poorer physical, psychological, and environmental QoL among Greek nursing students. These domain-specific findings extend existing evidence and support integrating digital well-being, self-regulation, and sleep-hygiene strategies into nursing education and student-support services.
