Sense of coherence has significant implications for the mental health of left-behind children in rural China. This study was conducted to explore the impact of physical exercise and social support on sense of coherence in rural left-behind children. A survey was conducted among 964 rural left-behind children in Hunan Province of China aged 10–15 (Mage = 12.01 ± 1.97 years; 529 girls and 435 boys). AMOS 21.0 software was applied to build the model and perform cross-lagged analysis. Physical exercise and social support in left-behind children predict each other, and physical exercise can positively predict social support and sense of coherence in left-behind children two months later (P < 0.05); social support can significantly positively predict sense of coherence in left-behind children two months later (P < 0.05). Both physical exercise and social support have an impact on sense of coherence in left-behind children, and physical exercise can affect sense of coherence in left-behind children through the mediating effect of social support. • Physical exercise has a positive impact on sense of coherence of rural left-behind children. • Social support has a positive impact on sense of coherence of rural left-behind children. • Physical exercise has a positive impact on social support of rural left-behind children. • Social support plays a partial mediating role between physical exercise and sense of coherence.

Objective: This study was designed to investigate the situation of social anxiety among left-behind children in rural areas of Hunan Province, China, and to study the effect of social anxiety on loneliness. Methodology: A total of 797 left-behind children were selected from rural areas in Hunan Province, China. The basic information questionnaire for left-behind children, Social Anxiety Scale for Children, Perceived Social Support Scale and UCLA Loneliness Scale were used for investigation. Results: (1) The social anxiety score of left-behind children in China is 6.84 ± 4.28, higher than non-left-behind children, and the score of boys is lower than that of girls, with no significant difference. The score of left-behind children in grade 5 is significantly lower than that of left-behind children in other grades. (2) The overall loneliness score is 16.30 ± 5.10, higher than non-left-behind children, and the score of boys is significantly higher than that of girls. (3) Social anxiety has a significant positive predictive effect on loneliness (P < 0.01). Regression analysis shows that social anxiety not only affects loneliness directly, but also affects loneliness indirectly through the mediating role of perceived social support. Conclusions: Social anxiety is a risk factor for loneliness of left-behind children in rural areas. In the influence of social anxiety on loneliness, social support plays a partial mediating role.

Exercise dependence is a psychological problem that cannot be ignored and is positively related to anxiety and depression of college students. However, only a few effective intervention methods are available to deal with exercise dependence. This study aims to investigate the intervention effects of motivation interviewing Chinese modified on the mental health of college students with exercise dependence. Thirty college students with exercise dependence were selected from Hunan University of Science and Technology in Hunan province of China to participate in the experiment. The participants were divided equally into the intervention and control groups. A three-week motivation interviewing Chinese modified session was conducted in the intervention group, whereas no intervention was carried out in the control group. This strategy allowed for the vertical and the horizontal comparison of the intervention objects' situation before and after the experiment. The State-Trait Anxiety Inventory and other Scales were used to evaluate the effects of the intervention and explore the intervention effects of motivation interviewing Chinese modified on the mental health of college students with exercise dependence. After three weeks of motivation interviewing Chinese modified, differences in state anxiety, depression, self-satisfaction, negative emotion, energy, and positive emotion in the intervention and control groups before and after the intervention appear to be statistically significant (P < 0.05). Motivation interviewing Chinese modified can improve the mental health level of college students with exercise dependence. Hence, motivation interviewing Chinese modified is good for the treatment of addiction behaviors and provides a reliable intervention method for exercise dependence. [ABSTRACT FROM AUTHOR]
