Objective: The coronavirus disease-2019 (COVID-19) pandemic has significantly altered daily life, potentially impacting children’s digital media usage. This study investigates changes in smart device usage among children in South Korea, considering the pandemic’s effects. Methods: A longitudinal analysis was conducted on a cohort of 313 children aged 8–11 years from 2018 to 2021. The study measured weekly usage of personal computers (PCs), tablet PCs, and smartphones, comparing pre-pandemic (up to 2020) and post-pandemic periods. Partial correlation analysis was employed to assess the impact of COVID-19, controlling for covariates such as age, household income, and parental education. Results: The analysis revealed a significant increase in smart device usage time following the onset of the pandemic. This increase remained statistically significant even after accounting for covariates. Notably, both age and maternal education level were significant factors influencing device usage. Conclusion This study demonstrates a significant shift in the digital behavior of children aged 8–11 in the context of the COVID-19 pandemic. The increase in smart device usage underscores the pandemic’s far-reaching impact on children’s daily routines and suggests a need for further research into its long-term effects. The findings highlight the importance of considering external societal changes when analyzing trends in digital media usage among children.

Objective: The primary purpose of this literature review is to explore and integrate findings from various psychological autopsy (PA) studies to identify critical risk factors associated with adolescent suicide and evaluate the methodologies employed in these investigations. Methods: A systematic review of 15 studies reporting psychological autopsies of adolescent suicides was conducted. Data sources included databases such as PubMed, Google Scholar, and RISS. Studies were selected based on empirical research focused on adolescent suicides, conducted since 1970, and written in English. Two reviewers independently screened and selected studies, with a third reviewer resolving any disagreements. The studies were analyzed for sample characteristics, included variables, and specific features of the PA methodology. Results: The review identified consistent findings across studies, highlighting the significant role of mental illnesses and sociodemographic factors in adolescent suicides. Methodological variations were noted in interview timing, source selection, and the use of semi-structured interviews. The review also emphasized the importance of comprehensive data collection, including social network and mobile activity data, to better understand suicide risk factors. Key challenges identified include retrospective data bias and cultural differences affecting the generalizability of findings. Conclusion The review underscores the need for standardized PA procedures, particularly tailored to adolescents, to improve the reliability and validity of findings. The consistent association of psychiatric disorders with suicide risk emphasizes the urgent need for effective mental health interventions. Future research should focus on developing ethical, culturally sensitive, and methodologically rigorous approaches to enhance the understanding and prevention of adolescent suicide.
