ABSTRACT
Background: The outbreak of COVID-19 had a widely negative effect on adolescents' academics, stress, and mental health. At a critical period of cortical development, adolescents' cognition levels are highly developed, while the ability of emotion control is not developed at the same pace. Faced with negative emotions such as stress and social loneliness caused by COVID-19, adolescents' "hot" executive function encounters severer emotional regulation challenges than ever before. Objective: The present study established a moderated mediation model to investigate the impact of rumination on "hot" execution function among Chinese middle school students during the COVID-19 pandemic, and the specific role of depression and mindfulness in the association. Materials and methods: This cross-sectional study was conducted on 650 students recruited from a province in central China. The participants completed questionnaires and experiment between July 2021 and August 2021. Rumination Responses Scales, Self-rating Depression Scale, and Mindful Attention Awareness Scale were used to measure the level of rumination, depression, and mindfulness. The reaction time and accuracy of the emotional conflict experiment were recorded to reflect the "hot" executive function. Results: The results of the moderated mediation model indicated that rumination of middle school students significantly and positively predicted depression in adolescents (ß = 0.26, p < 0.001). Meanwhile, the indirect effect of depression on the relationship between rumination and "hot" executive function was significant; depression partially mediated this relationship (word-face congruent condition: ß = -0.09, p < 0.01; word-face incongruent condition: ß = -0.07, p < 0.05). Furthermore, mindfulness buffered the association between rumination and depression, according to moderated mediation analysis (ß = -0.11, p < 0.001). For adolescents with low levels of mindfulness, the relationship was substantially stronger. Conclusion: In the context of the COVID-19 pandemic, middle school students' rumination would lead to depression, which can negatively impact their "hot" executive function. Besides, mindfulness could resist the adverse effect of rumination on depression. The educators should pay more attention to students' mental health, provide targeted strategies that boost mindfulness to promote their cognitive flexibility, and thus protect the normal development of their executive function during crisis events.
ABSTRACT
During the COVID-19 pandemic, the mental health state of adolescents had caused widespread concern, especially the various problems caused by the relationship between adolescents and their parents in the long isolation at home. Based on the mindfulness reperceiving model and Rogers's Self-theory, this study aimed to explore the roles of adolescents' self-concept clarity and mindfulness level in the relationship between parental psychological control and adolescent depression. A total of 1,100 junior high school students from China completed the questionnaires regarding parental psychological control, depression, self-concept clarity, and mindfulness. Moderated mediation analyses suggest that parental psychological control affects adolescent depression via self-concept clarity. The association between parental psychological control and depression is moderated by self-concept clarity. The effect was stronger among adolescents with high mindfulness levels than those with low. This study suggests that it is necessary to consider both parental factors and adolescents' factors in the future. The interventions on self-concept or mindfulness may ameliorate adolescent mental problems more effectively.
ABSTRACT
Background: The purpose of this study was to assess the level of knowledge, attitude and practice of COVID-19 among staff in China-Guinea Friendship Hospital, and to confirm the effect of nosocomial infection management. Methods: This cross-sectional study was conducted in December 2021. Information on socio demographic data, knowledge, attitude and practices related to COVID-19 was collected through a self-administered questionnaire. Results: A total of 143 employees participated in the survey, with a response rate of 99.31% and a vaccination rate of 95.10%. The average knowledge score of COVID-19 was 8.39 ± 1.3 points (10 points in total), without significant differences between subgroups with different demographic variables (P > 0.05); more than 80% of the participants had a positive attitude, and 72.03-93.01% of the participants could take appropriate preventive practices in different environments such as hospital, outdoor or home. Conclusion: The staff of the China-Guinea Friendship Hospital has good knowledge of COVID-19, a positive attitude and appropriate preventive practices. It can be concluded that the current nosocomial infection management is active and effective. Therefore, this study suggests that comprehensive activities such as training, promotion and supervision of COVID-19-related knowledge and countermeasures should be widely and continuously implemented in healthcare facilities, which will continuously improve the overall KAP level of hospital staff and play an important role in curbing the COVID-19 pandemic.
