Reduced Health-Related Quality of Life Due to Mobile Phone Dependence in a Sample of Chinese College Students: The Mediating Role of Chronotype and Sleep Quality

PURPOSE

Presenting a chain mediation model to investigate whether mobile phone dependence results in a reduction in health-related quality of life (HRQoL) among Chinese college students, through the mediating effect of chronotype and sleep quality.

DESIGN AND SETTING

A cross-sectional survey was conducted on students from a Chinese university using a validated structured questionnaire.

SAMPLE

2014 freshmen.

MEASURES

The study measured the students' level of mobile phone dependence using the Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use. Chronotype and sleep quality were measured by the Chinese version of the Morningness-Eveningness Questionnaire (MEQ) and the Pittsburgh Sleep Quality Index (PSQI), respectively. HRQoL was evaluated using the five-level EuroQol five-dimensional questionnaire (EQ-5D-5L), including a descriptive system and a visual analog scale (VAS).

ANALYSIS

Descriptive statistical analysis, correlation analysis, and mediation analysis.

RESULTS

Mobile phone dependence had a significant negative effect on HRQoL as indicated by both the EQ-5D-5L index score and EQ-VAS score (P < .001 for both). Additionally, it was found to significantly predict chronotype (MEQ score) (β = -.546, P < .001) and sleep quality (PSQI score) (β = .163, P < .001). Chronotype negatively predict sleep quality (β = -.058, P < .001), and sleep quality was a significant negative predictor of HRQoL (EQ-5D-5L index score, β = -.008, P < .001; EQ-VAS score, β = -1.576, P < .001).

CONCLUSION

Mobile phone dependence negatively impacts students' HRQoL through chronotype and sleep quality, and there is a chain mediating effect. Students should consider making lifestyle changes to improve their HRQoL and promote health.

Smartphone dependency and mental health among Chinese rural adolescents: the mediating role of cognitive failure and parent-child relationship

Background

With the widespread use of smartphones in daily life, smartphone dependency has become a global problem, especially among adolescents. Existing research studies have supported the association between smartphone dependency and the mental health of Chinese rural adolescents, but the underlying mechanism is still unclear.

Objective

The present study used a survey to test whether smartphone dependency may be associated with mental health in Chinese rural adolescents. The mediating role of cognitive failure and parent-child relationship was also examined.

Materials and methods

In total, 941 adolescents (45.91% male; mean age = 14.05, SD = 1.04) in rural areas of mainland China were recruited to complete four scales, including the Mobile Phone Dependence Scale (MPDS), Cognitive Failures Questionnaire (CFQ), Family Adaption and Cohesion Evaluation Scales (FACES), and Mental Health of Middle School Students Scale.

Results

The results showed that both cognitive failure and parent-child relationship acted as mediators in the effect of smartphone dependency on mental health among Chinese rural adolescents, and smartphone dependency also affected parent-child relationship by influencing cognitive failure, thus affecting mental health among Chinese rural adolescents indirectly.

Conclusion

The present study suggests that improving parent-child relationships and reducing cognitive failure can reduce the impact of smartphone dependency on the mental health of Chinese rural adolescents.
