ABSTRACT
This paper investigates the mood changes of youth groups during the social closure control of the COVID-19 pan-demic and the primary causes of those changes, taking Chinese online video platforms as an example. We also compare the main concerns of various periods to provide feasible references and suggestions on psychological interventions for young people during the social closure control period. In this study, we identified mood changes during the COVID-19 pandemic with 31,213 comments on the news videos of the Bilibili video platform through four stages: data collection, data processing, LDA topic modeling, and mood identification. Through a comparative analysis, we investigated the topical features of young people's mood changes in three COVID-19 periods: pre-, mid-, and late-epidemic. As a result, we found that social isolation measures such as closure and homeschooling with long-term Internet use during the epidemic were more likely to cause depression in young people. © 2023 IEEE.
ABSTRACT
Background Due to the limitation of drug treatment and other adverse reactions, many psychological treatments always adopt rehabilitation training or non-drug intervention methods, while physical exercise is considered as an auxiliary way. A mass of literature has verified the therapeutic benefits of physical exercise to reduce depression and anxiety in clinical populations. However, little attention is paid to the mental health benefits of exercise for non-clinical populations. The purpose of this meta-analysis is to systematically aggregate and quantify findings of the effect of physical exercise on depression and anxiety in non-clinical populations, through which to evaluate whether physical exercise intervention as a non-drug means can effectively improve the depressive and anxious moods of college students. Significance This paper combines sport and psychotherapy and links kinesiology and psychology, which can deepen readers' understanding and stimulate their interest in the practice of sport and exercise psychology. The 2019 novel coronavirus disease (COVID-19) has swept the world, causing a global epidemic with serious physical and psychological consequences, and this study may help policymakers and health care professionals to make effective recommendations for psychological interventions for college students. Methods The study was based on five electronic databases: CNKI, Wan Fang Data, SinoMed, PubMed, and Web of Science. The quality of the selected articles was evaluated by the PEDro scale. The Meta-Analysis was performed using R-4.0.4, which computed pooled estimates of effect size and respective 95% confidence intervals (95% CI) for intervention. Bias and sensitivity analyses were calculated to explore the source of heterogeneity, and subgroup analyses were performed according to time, frequency, and event. Results Synthesizing all the trials, the results show that the study heterogeneity of physical exercise on the improvement of depressive mood in college students is relatively high (I2=63%, P<0.01), which has a medium effect (SMD=-0.63, 95% confidence interval=-0.80 to -0.46). The results reveal low heterogeneity in anxious mood (I2=36%, P = 0.04), with a medium effect (SMD=-0.58, 95% confidence interval=-0.71 to -0.44). Conclusion The Meta-Analysis confirms the effective and positive role of physical exercise in reducing depressive and anxious moods of college students. Physical exercise can be used as a non-medical method to improve the mental health state of college students and promote full development. Further research should evaluate the impact of various sports and specific exercise prescriptions on college students' negative emotions, so as to apply them to complementary and alternative therapies.
ABSTRACT
This study investigated the impact of increased depressive feelings during the COVID-19 pandemic on the suicidal behavior of Korean high school students using the 17th Korea Youth Risk Behavior Web-Based Survey (KYRBS). We classified the independent variables into four groups ("no depressive mood and no increase in depressive feelings [group A]", "no depressive mood and increase in depressive feelings [group B]", "depressive mood and no increase in depressive feelings [group C]", and "depressive mood and increase in depressive feelings [group D]"). Compared to group A, group D showed an odds ratio of 18.30 in men and 14.87 in women for suicidal behavior after accounting for demographic and health behavioral characteristics. We found that depressive mood and a relatively short-term increase in depressive feelings had a synergistic effect, rather than an additive one, on suicidal behavior. Based on this result, we claim that an appropriate intervention method is necessary to prevent adolescents' depressive mood from developing into suicidal behavior during the pandemic.
