Outline
To investigate the dynamic development trajectories of internet addiction in children and adolescents after COVID-19, and the influence of factors such as gender, ethnicity, parental education and non-suicidal self-injury, and provide a reference for the formulation of precision psychological intervention programs.
In the Chengdu Positive Child Development Cohort, we conducted follow-up surveys at four time points from December 2019 to June 2022, using the Internet Addiction Scale (IAT) and the Deliberate Self-Injury Scale (DSHI). The study involved 3 865 students from grades 1 to 6. The latent growth mixture model (LGMM) was used to analyze the development trajectory of internet addiction in children and adolescents. Factors associated with changes in each latent category of internet addiction were analyzed using multiple logistic regression.
There was a clear upward trend in internet addiction among children and adolescents over time. The developmental trajectories among children and adolescents with internet addiction could be categorized into four distinct groups, labeled as C1 "low-level-slow-rise group" (77.7%), C2 "low-level-deteriorating group" (9.3%), C3 "high-level-remitting group(8.2%) and C4 "high-level-stable group" (4.8%). Males, non-Han ethnicity, maternal education below junior high school, and non-suicidal self-injury were identified as risk factors associated with adverse trajectory changes in internet addiction among children and adolescents.
Children and adolescents with internet addiction exhibited significant group heterogeneity and individual differences in their development trajectories, so precise psychological intervention programs should be given according to different categories to use limited psychological resources to improve the intervention effect rationally.
