Abstract： As a kind of negative social behavior, aggression not only brings harm to others, but also disturbs social harmony and order and threatens public security. Numerous studies have discussed the inducing factors of aggression, among which social exclusion has been widely concerned as a strong predictor. However, the studies about the association between social exclusion and aggression have shown mixed results. Theoretically, there are two main arguments about the relationship between social exclusion and aggression. The general aggression model suggests that social exclusion triggers negative emotions, hostile cognition, or a high level of physiological arousal, which leads to aggression. While the emotional numbness hypothesis argued that social exclusion causes individuals to be a state of physiological or emotional numbness, which avoids the occurrence of aggressive behaviour. Empirically, the effect sizes of this relationship reported in the existing literature were far from consistent, with r values ranging from -0.02 to 0.74. Therefore, this meta-analysis was conducted to clarify the strength of the relationship between social exclusion and aggression and reveal possible moderators.
Through literature retrieval, 92 studies (99 independent effect sizes, a total of 65564 subjects) met the inclusion criteria were selected. A random-effects model was selected to conduct the meta-analysis in Comprehensive Meta-Analysis 3.3 software, aiming at testing our hypotheses. The results of heterogeneity test illustrated that there was significant heterogeneity among 99 independent effects, indicating that the random effect model is suitable for subsequent meta-analysis. Based on the funnel chart and Egger’s regression test of intercept, no significant publication bias was found in the included studies.
The main effect analysis indicated a significant positive correlation between social exclusion and aggression (r = 0.38, 95% CI [0.34, 0.41]); The moderation analyses revealed that the relationship between social exclusion and aggression was moderated by age, research methods, aggression types (reactive aggression vs. proactive aggression), social exclusion and aggression measurement tools, and research design (cross-sectional study vs. longitudinal study), but not by individualism index and gender.
The results of this meta-analysis can clarify the controversy of the correlation between social exclusion and aggression, indicating that excluded individuals are often accompanied by the increase of aggression level. Future research are encouraged to strengthen the prevention and intervention of aggressive behavior caused by social exclusion among low-age groups, especially preschool children and primary school students.

Abstract： Estimating the prevalence of college students’ mental health problems in China can provide evidence support for the improvement of mental health policies and the development of educational activities. A meta-analysis was conducted on the prevalence and influencing factors of major mental health problems among Chinese college students during 2010~2020. The results showed that sleep problem, depression and nonsuicidal self-injury were severer problems among college students. In recent ten years, the prevalence of anxiety, depression, sleep problem and suicide attempt among college students have increased significantly, while the prevalence of nonsuicidal self-injury has decreased significantly. Measuring tools, detection standards and detection time were the key factors leading to different prevalence. On the whole, the mental health of college students in northeast and central China was better than that in western and eastern China. Gender, birthplace, only child or not were not the key factors affecting the mental health of college students. In the future, we should endeavor to develop mental health assessment tools and determine detection standards that fit Chinese characteristics and are in line with the psychological characteristics of Chinese college students, and on this basis, carry out large-scale screen and control of psychological and behavioral problems.

Abstract： " The prevalence of mental health problems of senior high school students in China needs urgent attention. It has attracted many researchers’ attention, but their results were inconsistent. In order to clarify the detection rates and influencing factors of mental health problems of senior high school students in China in recent ten years, we performed a meta-analysis using 252 retrieved studies. The results showed that the prevalence from high to low were depression (28%), anxiety (26%), sleep problems (23%), self-injury (23%), suicidal ideation (17%), somatization (10%), suicide plan (7%), and suicide attempt (3%). The prevalence of mental health problems of senior high school students in China was affected by the year of publication, measurement tools, detection standards, detection time, grade, and region. In the future, efforts should be made to prepare standardized evaluation tools, build a long-term mechanism of mental health education, and focus on the mental health problems of senior class and underdeveloped area senior high school students.

Abstract： The prevalence of mental health problems of primary school students in China were different. In order to integrate the survey results and analyze the causes, meta-analysis was used to synthesize the relevant studies in recent ten years from 2010 to 2020 (101 articles, 289396 subjects). The results showed that: (1) The prevalence of mental health problems in primary school students from high to low were sleep problems (25.2%, 95%CI = [0.160, 0.373]), depression (14.6%, 95%CI = [0.120, 0.175]), anxiety (12.3%, 95%CI = [0.063, 0.227]), aggressive behavior (4.1%, 95%CI = [0.017, 0.099]), withdrawal (3.8%, 95%CI = [0.023, 0.062]), disciplinary behavior (3.7%, 95%CI = [0.018, 0.073]) and somatization (3.6%, 95%CI = [0.017, 0.073]). (2) Measurement tools, measurement standards and detection period were the key factors causing the fluctuation of prevalence of mental health problems among primary school students in China. Generally speaking, the overall mental health status of primary school students in China is acceptable except that the prevalence of sleep problems, depression and anxiety are high. In the future, we should develop mental health assessment tools and detection standards suitable for Chinese primary school students to provide support for the prevention and accurate intervention of mental health problems.

Abstract： The prevalence of mental health problems of junior high school students is very different in many studies, which fails to provide sufficient basis for the formulation of mental health policy and the construction of mental health service system. In order to identify the overall prevalence of mental health problems and clarify its influencing factors, a meta-analysis of literature retrieved from 2010 to 2020 was performed. The results showed that: (1) Junior high school students faced different degrees of mental health problems, among which the prevalence of anxiety, depression and self-harm ranked in the top three. (2) Some aspects of mental health problems of junior high school students showed a worsening trend with the development of the years, especially anxiety and suicide attempt. (3) The prevalence of mental health problems of junior high school students is seriously affected by the inconsistency of measurement tools, detection criteria and detection time. (4) Generally, the prevalence of mental health problems in junior high school students increases with the grade, especially anxiety. (5) The prevalence of mental health problems among girls is higher than that of boys, especially suicide. (6) Junior high school students in the central and western regions are more likely to have mental health problems, especially anxiety and self-harm, than those in the northeast and eastern regions. In the future, scientific measurement tools and standards should be developed based on the Chinese background, and a mental health dynamic monitoring system and school mental health service system should be established.

Abstract： Loneliness and mobile phone addiction are common phenomena in our daily life, seriously affecting our physical and mental health. Recently, numerous empirical studies have discussed the relationship between these two constructs based on different theoretical perspectives. However, the reported effect sizes of this relationship based on cross-sectional designs are far from consistent. Therefore, this meta-analysis was conducted to explore the strength and moderators of the relationship between loneliness and mobile phone addiction. One hundred and thirty-one studies consisting of 134 independent samples involving 73,543 participants were identified and a random-effects model was selected to conduct this meta-analysis. The results of the funnel plot and Egger’s intercept illustrated no publication bias. Furthermore, the results of the main-effect test indicated that there was a moderate and positive correlation between loneliness and mobile phone addiction (r = 0.25, 95%CI= [0.23, 0.27]). Additionally, the moderation analyses revealed that the strength of the relationship was moderated by the type of participants, but not by gender and measurement tools of loneliness and mobile phone addiction. The results supported the compensatory Internet use theory and the deficient self-regulation model. Longitudinal or experimental studies are needed in the future to further explore the direction of the relationship between loneliness and mobile phone addiction.

Abstract： More and more researchers are concerned about the threat and impact of temperature and temperature variability on mental health. Temperature and temperature variability has direct or indirect effects on mental health indicators such as emotional well-being, emotional disorders such as depression, schizophrenia, organic mental disorders such as Alzheimer's disease, substance abuse and dependence, suicidal ideation and behavior. Most researchers explain the mechanism of temperature's influence on mental health from physiological aspects such as meteorological emotional effect, brown adipose tissue theory, and serotonin theory. Children and adolescents, the elderly, workers are vulnerable to temperature and high temperature pressure. There are also gender, age, and socioeconomic status differences in the effects of temperature change on mental health. In future studies, it is necessary to further distinguish different temperature indexes, pay more attention to the relationship between low temperature and mental health, control the interference of other factors on the relationship between temperature and mental health, and reveal the differences between individuals and groups.

Abstract： Social anxiety has become a serious public health concern in our society. It is imperative to examine risk factors for this problem. Among these predictive variables, self-esteem has been one of the most examined risk factors for social anxiety. Numerous studies have explored the relationship between self-esteem and social anxiety among Chinese students. However, these results are far from consistency. Therefore, this meta-analysis was conducted to explore the relation between self-esteem and social anxiety among Chinese students, and investigate the moderating effects of measurement tools of social anxiety, participant types, and gender. Through literature retrieval, 58 independent effect sizes together with 32181 participants which met the inclusion criteria of meta-analysis were selected. Heterogeneity test indicated that random effects model was appropriate for the meta-analysis. The results of funnel plot and Egger’s intercept illustrated no publication bias. Main-effect test indicated a significant negative correlation between self-esteem and social anxiety (r = −0.35, 95%CI = [−0.39, −0.31]). Further moderation analyses revealed that the association between self-esteem and social anxiety was moderated by measurement tools of social anxiety, but not by the type of participants and gender. The results supported the fear management theories of self-esteem and the cognitive models of social anxiety. Longitudinal or experimental studies are needed in the future to reveal the causal relationship between self-esteem and social anxiety.
