Abstract
Background and aims: Adolescent mental health has declined in recent decades. Few studies have explored whether shifts in interpersonal behaviours- both in-person and online- can help explain this decline. Using data from two Swedish cohorts (2007-2008, 2023-2024), we examined (1) 15-year time trends (2007-2008 vs. 2023-2024) in interpersonal behaviours (victimization, aggression, prosocial behaviours) and mental health (externalizing/internalizing problems); (2) one-year bidirectional associations between them; (3) the unique role of cybervictimization/cyberaggression in relation to mental health; and (4) adolescents' accounts of online experiences that made them 'feel bad'.
Methods: Two longitudinal school cohorts of Swedish adolescents (2007-2008: N = 911-987, Mage = 13.71-14.76 years; 2023-2024: N = 768-806, Mage = 13.89-14.89 years) completed self-report measures of interpersonal behaviours and mental health. In 2023-2024, a subset of adolescents (n = 127, 16.5%) answered open-ended questions about negative online experiences.
Results: From 2007 to 2008 to 2023-2024, prosocial behaviours moderately declined for girls and boys, while internalizing problems increased moderately for girls and weakly for boys. Meanwhile, victimization, aggression, and externalizing problems increased at a weak-to-moderate level among girls. Victimization and being treated well by others showed moderate bidirectional relationships with mental health. Cybervictimization/cyberaggression had weaker associations with mental health than did in-person behaviours. According to the qualitative analysis of negative online experiences, adolescents reported harassment, social exclusion, perceived standards/expectations, time-consuming activities, and exposure to distressing content.
Conclusions: Deteriorating adolescent mental health over the past 15 years has occurred alongside rising interpersonal difficulties. The findings further suggest a reciprocal relationship between social challenges and mental health, with hostile online environments amplifying- but not primarily driving- these issues. A holistic perspective that accounts for both in-person and online experiences is essential to better understand and support adolescent well-being.
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.
