Perceived Stress and Smartphone Application-Based Addiction Among Chinese Young Adults: The Mediating Role of...

Previous research has established the significant role of perceived stress in contributing to Smartphone addiction, but the specific effects and mechanisms through which perceived stress influences smartphone application-based addiction (SABA) among young adults remain insufficiently understood.

This study investigates the relationship between perceived stress and the smartphone application-based addiction (SABA) in emerging adulthood, focusing on the mediating role of psychological distress and the moderating role of self-control.

We conducted a cross-sectional survey of 1.911 young adults in Southwest China, utilizing the Perceived Stress Scale (PSS-4), the Smartphone Application-Based Addiction Scale (SABA), the Patient Health Questionnaire-4 (PHQ-4), and the Brief Self-Control Scale (BSCS).

Perceived stress positively predicted psychological distress (β = .47, t = 24.38, P < .001), psychological distress positively predicted Smartphone application-based addiction (β = .42, t = 7.04, P < .001), and perceived stress positively predicted smartphone application-based addiction (β = .65, t = 11.46, P < .001). Psychological distress was a mediating variable between the relationship between perceived stress and smartphone application-based addiction, with a mediating effect size of .19 (95% CI = [.13, .26]), accounting for 22.62% of the total effect. Self-control moderated the relationship between perceived stress and psychological distress in young adults (β = -.03, t = -7.09, P < .001).

Our findings reveal a positive correlation between perceived stress and SABA, with psychological distress serving as a mediator. The impact of perceived stress on SABA is more signiicant among individuals with lower self-control, indicating that targeted interventions for these groups may be particularly beneicial.
