Article Abstract
Background: Physical activity and experiencing bullying is a protective and risk factor for mental health, respectively. Adolescents who suffer from bullying tend to be trapped in rumination, leading to mental health problem. However, the interaction among them from the perspective of increasing protective factors and reducing risk factors is unclear. This study explored whether rumination mediated the association between experiencing bullying and mental health problems and the moderating role of physical activity.
Method: This study investigated 13,983 students from high school in Jiangxi Province, China, and assessed for experiencing bullying, rumination, mental health problems (depressive, anxiety, and insomnia symptoms), and physical activity. Moderated mediation analysis was conducted using R software (version 4.1.1).
Results: Significant differences were observed in rumination, physical activity and mental health problems between adolescents who have experienced bullying and those who have not (p < 0.001). Rumination mediated the relationship between experiencing bullying and depressive symptoms (β= 0.45, 95 % CI [0.42, 0.48]), anxiety symptoms (β= 0.37, 95 % CI [0.35, 0.39]), and insomnia symptoms (β= 0.36, 95 % CI [0.33, 0.38]). Moreover, physical activity moderated the relationship between rumination and depressive symptoms (coeff = -0.03, p < 0.001), anxiety symptoms (coeff = -0.02, p < 0.001), and insomnia symptoms (coeff = -0.01, p < 0.001).
Conclusions: Rumination and physical activity mediated and moderated, respectively, the relationship between experiencing bullying and adolescents' mental health problems. These findings indicate that schools and society should establish a campus bullying early warning system, pay attention to bullying incidents and promote physical activity.

In many countries little is known about the attitudes and ethical beliefs of practicing psychiatrists towards the use of coercive practices. This is true as regards Russia where coercion was used for political purposes during the Soviet period. However, substantial changes have occurred in the psychiatric system in recent decades with a focus on patients' rights and the idea of consent.

Background: The ability to access and evaluate online health information is essential for young adults to manage their physical and mental well-being. With the growing integration of the internet, mobile technology, and social media, young adults (aged 18-30 years) are increasingly turning to digital platforms for health-related content. Despite this trend, there remains a lack of systematic insights into their specific behaviors, preferences, and needs when seeking health information online.

Background: Ecological momentary assessment (EMA) is increasingly being incorporated into intervention studies to acquire a more fine-grained and ecologically valid assessment of change. The added utility of including relatively burdensome EMA measures in a clinical trial hinges on several psychometric assumptions, including that these measure are (1) reliable, (2) related to but not redundant with conventional self-report measures (convergent and discriminant validity), (3) sensitive to intervention-related change, and (4) associated with a clinically relevant criterion of improvement (criterion validity) above conventional self-report measures (incremental validity).
Objective: This study aimed to evaluate the reliability, validity, and sensitivity to change of conventional self-report versus EMA measures of rumination improvement.
