Longitudinal patterns of adolescent mobile phone dependence: Results from the person-centered approach

This study aimed to identify possible subgroups of adolescent mobile phone dependence and explore whether each subgroup remains stable over time and the effects of three important interpersonal supports. A total of 1214 adolescents completed three surveys across one year. The study found that there were three growth subgroups of mobile phone dependence: the “low-risk” group, the “medium-risk” group, and the “high-risk” group. The “low risk” and “high risk” groups showed a decreasing trend, while the “medium risk” group showed an increasing trend. The transformation occurred between subgroups. Friend support decreased the likelihood of transitioning to “high-risk” groups and other support increased the likelihood of transitioning to “low-risk” groups. This study contributes to understanding the developmental differences in adolescent mobile phone dependence. It emphasizes the importance of considering interpersonal support in reducing mobile phone dependence. This study could stand as a base for further studies in mobile phone dependence.
