摘要

Excessive mobile phone use has raised concerns about addiction among college students, yet research specifically addressing firefighter students remains limited. This study investigates how meaning in life (MIL) is associated with problematic smartphone use (PSU) in firefighter students, with positive affect (PA) and negative affect (NA) as mediators. Data from 606 participants (Mage = 22.73; SD = 2.67, 97% male) were collected across two waves, assessing MIL, PA, NA, and PSU. Structural Equation Modeling (SEM) with item parceling revealed that both PA (B = − 0.09, SE = 0.04, p = .042, 95% CI [-0.176, − 0.003]) and NA (B = − 0.05, SE = 0.01, p = .001, 95% CI [-0.073, − 0.017]) significantly mediate the MIL-PSU relationship. Specifically, higher MIL correlates with reduced PSU, mediated by increased PA and decreased NA. These results highlight the critical role of emotional states in the MIL-PSU link, offering insights for intervention strategies that focus on enhancing MIL and emotion to curb PSU in firefighter students. Additionally, the insignificant direct association between T1-MIL and T2-PSU among students with prior firefighting experience, in the absence of mediation by PA/NA, suggests the important and complex role of previous firefighting experience, which should be further explored when developing interventions tailored to firefighter students with and without such experience.
