Outline
To analyze the heterogeneity of mobile phone dependence development trajectory in middle school students and its association with loneliness and self-control ability, so as to provide reference for the prevention of mobile phone dependence in middle school students.
A total of 941 grade 1 students from 4 public middle schools in Xiangxi Autonomous Prefecture, Hunan Province were selected for the follow-up survey by random cluster sampling from October 2023 to April 2024 and October 2024. Mobile Phone Addiction Index (MPAI), University of California, Los Angeles Loneliness Scale-20 (UCLA-20) and Self-control Scales (SCS) were used for questionnaire survey. The heterogeneity of the developmental trajectory of middle school students' mobile phone dependence was analyzed by the latent growth curve model (LGMM), and the influencing factors of the developmental trajectory of middle school students' mobile phone dependence were explored by multiple Logistic regression analysis.
The development trajectory of middle school students mobile phone dependence could be divided into four categories: C1 "low risk slow decline group (n=438, 44.6%)", C2 "medium risk slow rise group (n=272, 29.7%)", C3 "high risk rapid decline group (n=73, 8.6%)" and C4 "high risk rapid rise group (n=158, 17.1%)". There were significant differences in the distribution of mobile phone dependence development track heterogeneity subgroups among sex, only child, lodging, and left-behind students (χ2=117.79, 44.88, 37.09, 130.50, P < 0.01). The results of the multinomial Logistic regression model analysis showed that, with C1 group as the reference, C2, C3, and C4 were positively correlated with students loneliness [OR (95%CI)=1.04 (1.02-1.06), 1.11 (1.08-1.14), 1.12 (1.09-1.14)]; C2 and C4 groups were negatively correlated with students self-control [OR(95%CI)=0.97(0.96-0.99), 0.95(0.93-0.97)] (P < 0.01).
The development trajectory of mobile phone dependence among middle school students is heterogeneous. Reducing the loneliness of individuals and cultivating good self-control ability are helpful to alleviate mobile phone dependence behavior among middle school students.
