We investigated the mediating roles of anger and hostility in the relationship between social support and moral disengagement. Participants were 315 college students who completed the Perceived Social Support Scale, the Aggression Questionnaire to assess anger and hostility, and the
Moral Disengagement Questionnaire. Multiple mediation analysis results indicated that high levels of anger and hostility were associated with low levels of social support and high levels of moral disengagement. In addition, the total indirect effects and specific indirect effect of social
support on moral disengagement through anger and hostility were all significant, suggesting that anger and hostility mediated the relationship between social support and moral disengagement. Implications of these findings are discussed.

The purpose of this study was to examine parents' perceived social change and its relations with adolescents' reports of childrearing attitudes in urban and rural China. The participants were high school students and their parents in a Northern region of China. Parents completed a measure of perceived social change, and the adolescents completed a measure of childrearing attitudes including parental warmth, control, and encouragement of independence. The results indicated that urban parents had higher scores than rural parents on major dimensions of perceived social change including work-related opportunities, self-improvement in work, and high-tech experiences. Urban adolescents reported lower parental control and higher parental encouragement of independence than rural adolescents. In addition, parents' reports of opportunities and prospects were positively associated with adolescents' reports of parental warmth and encouragement of independence in childrearing across the urban and rural groups, suggesting that parents who perceived more challenges and opportunities to pursue self-advancement and personal career goals were more likely to support the use of warm and sensitive parenting and to encourage their children to develop independent behaviors. The results indicated the implications of social change for socialization and adolescent development in Chinese context.

This study aimed to investigate the features of only child status related to physical health, mathematics achievement, and school feelings and expectations from a different perspective. A representative sample of 91,619 Grade 4 students with an average age of 10.4 ± 0.7, among which 28,631 were only children, were assessed. We used propensity score matching (PSM) and the average treatment effects on the treatment to analyze data. The treatment was the only child of a family. The results indicated that only children have better academic achievement and school feelings (only for urban only child girls), while non-only children have better physical status and anaerobic fitness (AF). In addition, gender and rural vs. urban areas differences were also explored. The adverse situation for rural only boys is emphasized for families, researchers, and governments to focus on. Some suggestions are given under the Two- and Three-Child Policy.

Purpose– The purpose of this paper is to investigate the developmental trajectory and patterns of physical aggression and relational aggression over time, and also to examine the gender differences of the three-year developmental process as well as the impact of the developmental trajectory on mental health.Design/methodology/approach– Participants: the participants of this study were newly enrolled junior school students. The study spanned three years with continuous tracking performed once every other year. Measures: class play questionnaire. Aggressive behaviors were measured by an adaptive Chinese version of the revised class play assessment. Statistical analysis: to address the questions of the present study, the latent class growth model (LCGM) was used to analyze the three-year longitudinal data by Mplus 6.1.Findings– The initial level of physical aggression in boys was higher than that in girls. There were three types of developmental trajectory for boys, corresponding to a lower initial level-increasing group, a middle initial level-increasing group and a higher initial level-stable group. However, girls demonstrated different patterns, corresponding to a lower initial level-increasing group, a middle initial level-increasing group and a higher initial level-decreasing group. In contrast to the physical aggression, the initial level of relational aggression in boys was lower than that in girls. There were four types of developmental trajectory for boys, corresponding to a lower initial level-increasing group, a middle initial level-increasing group, a middle initial level-declining group and a higher initial level-declining group. Girls illustrated different patterns, corresponding to a lower initial level-stable group, a middle initial level-increasing group and a higher initial level-declining group. Different developmental trajectory of physical and relational aggression would influence the interpersonal relationship.Originality/value– This paper used a person-centered latent variable approach instead of the variable-centered approach to investigate the developmental trajectory and patterns of physical aggression and relational aggression over three year by employing the LCGM. The initial level of physical aggression in boys was higher than that in girls. In contrast, the initial level of relational aggression in boys was lower than that in girls. There were gender differences in the pattern of physical and relational aggression development trajectory. Different developmental trajectory of physical and relational aggression would influence the interpersonal relationship.

AbstractAn alarming number of students drop out of junior high school in developing countries. In this study, we examine the impacts of providing a social–emotional learning (SEL) program on the dropout behavior and learning anxiety of students in the first two years of junior high. We do so by analyzing data from a randomized controlled trial involving 70 junior high schools and 7,495 students in rural China. After eight months, the SEL program reduces dropout by 1.6 percentage points and decreases learning anxiety by 2.3 percentage points. Effects are no longer statistically different from zero after 15 months, perhaps due to decreasing student interest in the program. However, we do find that the program reduces dropout among students at high risk of dropping out (older students and students with friends who have already dropped out), both after eight and 15 months of exposure to the SEL program.
