The effect of neuroticism on mobile phone addiction among undergraduate nursing students: a moderated mediation model.

BACKGROUND

Mobile phone addiction (MPA) has numerous deleterious effects on college students, including depression, anxiety, cognitive impairments, and sleep disorders. Undergraduate nursing students play a crucial role as a significant reserve workforce in clinical nursing practice, and their compromised mental health status significantly influences the quality of nursing work and nurse-patient relationships in the future.

OBJECTIVES

This study aims to investigate the associations between neuroticism and MPA among undergraduate nursing students, the mediating effect of self-control and the moderating effect of psychological capital.

METHODS

A total of 900 undergraduate nursing students participated in the survey, wherein the Eysenck Personality Questionnaire Short Form Scale China Version-Neuroticism Subscale (EPQ-RSC-N), Self-Control Scale (SCS), Positive Psychological Capital Questionnaire (PPQ), and Mobile Phone Addiction Tendency Scale (MPATS) were employed for assessment. To analyze the available data, various statistical methods were utilized, including common method bias test examination, descriptive statistics, chi-square tests, independent samples t-tests, Pearson's correlation analyses, as well as the Hayes' PROCESS Macro models 4 and 14.

RESULTS

(1) The prevalence of MPA in this study was found to be 34.89%. (2) The MPA was positively correlated with neuroticism (r = 0.287, p < 0.001), and was negatively correlated with self-control (r = -0.467, p < 0.001) and psychological capital (r = -0.260, p < 0.001). (3) Self-control played a partially mediating role in the association between neuroticism and MPA, with an effect size of 0.151, accounting for 52.98% of the total effect. (4) Psychological capital played a moderating role in the association between self-control and MPA. More specifically, with an increase in the level of psychological capital increases, the predictive effect of self-control on MPA gradually strengthens (β = -0.072, SE = 0.019, t = -3.708, p < 0.001).

CONCLUSION

The prevalence of MPA was relatively high among undergraduate nursing students, with neuroticism exerting a direct influence on it. Self-control served as a mediating factor that could partially alleviate MPA associated with neuroticism. Psychological capital has the ability to regulate the relationship between self-control and MPA. Therefore, enhancing self-control capabilities and cultivating psychological capital levels can effectively manage MPA among undergraduate nursing students.
