Fatigue as a central bridge: temporal dynamics between problematic smartphone use and depressive symptoms in Chinese adolescents.
Background: The prevalence of problematic smartphone use (PSU) has been increasing among adolescents in recent years, often co-occurring with depressive symptoms, which poses additional challenges to adolescent mental health. Despite growing concern, the mechanisms underlying the co-occurrence of PSU and depression remain poorly understood. To address this gap, the current study employed cross-lagged panel network analysis to investigate the temporal relationships between specific symptoms of PSU and depressive symptoms over time.
Methods: Data were collected at three time points (T1, T2, and T3), with six-month intervals between each wave. Participants self-reported their levels of depressive symptoms and PSU. A total of 558 participants (52.5% male; mean age at T1 = 13.83, SD = 0.78) were included in the final analysis. Two cross-lagged panel networks were constructed to examine the bidirectional relationships between depressive symptoms and PSU from T1 to T2 and from T2 to T3.
Results: In the T1-T2 network, Withdrawal from PSU and Fatigue from depressive symptoms not only emerged as the most influential symptoms but also acted as bridge symptoms linking the co-occurrence of these two mental health issues. In the T2-T3 network, the structure of network became denser, with the most influential symptoms primarily stemming from depressive symptoms, such as Sleep Disturbance and Feeling of Failure. Negative Life Consequences from PSU and Fatigue from depressive symptoms served as key bridge symptoms.
Conclusions: The findings provide valuable insights into the temporal dynamics underlying the co-occurrence of PSU and depressive symptoms during adolescence, with Fatigue appearing to play a significant role in linking these two mental health issues over time. Future studies should account for individual differences in how symptoms evolve over time and explore how these symptoms develop and persist at the individual level.
期刊介绍：
Child and Adolescent Psychiatry and Mental Health, the official journal of the International Association for Child and Adolescent Psychiatry and Allied Professions, is an open access, online journal that provides an international platform for rapid and comprehensive scientific communication on child and adolescent mental health across different cultural backgrounds. CAPMH serves as a scientifically rigorous and broadly open forum for both interdisciplinary and cross-cultural exchange of research information, involving psychiatrists, paediatricians, psychologists, neuroscientists, and allied disciplines. The journal focusses on improving the knowledge base for the diagnosis, prognosis and treatment of mental health conditions in children and adolescents, and aims to integrate basic science, clinical research and the practical implementation of research findings. In addition, aspects which are still underrepresented in the traditional journals such as neurobiology and neuropsychology of psychiatric disorders in childhood and adolescence are considered.
