Background: Mobile phone addiction has many negative effects on undergraduate students, such as depression, anxiety, loneliness, inattention, cognitive impairment, weakened immunity, impaired vision and sleep disturbance. Nursing students are the reserve army and important reserve force of clinical nursing, and poor mental health has an important impact on the quality of work and the nurse-patient relationship in future nursing. Objective: To investigate the relationship between neurotic personality and mobile phone addiction in undergraduate nursing students, and to examine the pathways through which stress perception and self-control play a role in the relationship by constructing a chain-mediated model. Methods: Nine hundred undergraduate nursing students from 10 universities in Shaanxi Province were selected as subjects. The Eysenck Personality Questionnaire Short Form Scale China Version-Neuroticism subscale, the Stress Perception Scale, the Self-Control Scale, and the Mobile Phone Addiction Tendency Scale for College Students were used to assess neurotic personality, subjective stress, self-control, and mobile phone addiction tendency, respectively, in undergraduate nursing students. Chained mediated effects analysis was performed using Model 6 of the SPSS procedure written by Hayes, and mediated effects testing was performed using the bootstrap method. Results: (1) The detection rate of mobile phone addiction among undergraduate nursing students was 34.89%. (2) The propensity for mobile phone addiction among undergraduate nursing students was positively correlated with both neurotic personality (r = 0.287, P < 0.01) and stress perception (r = 0.362, P < 0.01), and negatively correlated with self-control (r = -0.468, P < 0.01). (3) Stress perception and self-control mediated the relationship between neurotic personality and mobile phone addiction, with relative mediation effect values of 19.73% and 22.87%, respectively. (4) Neurotic personality may have an indirect effect on the tendency to mobile phone addiction among undergraduate nursing students through the stress perception-self-control chain, with a relative mediation effect value of 22.42%. Conclusion: Neurotic personality, stress perception and self-control are important influencing factors in triggering mobile phone addiction among undergraduate nursing students, and neurotic personality not only directly affects the tendency of mobile phone addiction among undergraduate nursing students, but also may indirectly affect their tendency to become mobile phone addicted through the chain mediating effect of stress perception and self-control. |
