Leaders of Peer Groups in Chinese Early Adolescents: The Roles of Social, Academic, and Psychological Characteristics in Group Leadership

Leadership in peer groups is an important issue in adolescent socioemotional development, yet it has received limited attention in research. This one-year longitudinal study examined peer group leadership and the roles of social, academic, and psychological characteristics in the dynamics of group leadership. Participants included 1061 Chinese students (initial mean age =11.17 years; SD = 6.98 months; 49.4% female). Data were collected from peer assessments, teacher ratings, and self-reports. The longitudinal social network analysis (SIENA) indicated that peer group leadership was fluid with leadership status evolving over time across groups in a hierarchical manner. Adolescents displaying higher social competence and aggression and lower shyness were more likely to become group leaders. Academic performance and loneliness were not significantly associated with the dynamics of peer group leadership. The results help understand peer group leadership and contributions of social behaviors to the attainment of leadership status in peer groups in early adolescence.

Changes in adolescents' daily-life solitary experiences during the COVID-19 pandemic: an experience sampling study

BACKGROUND

Adolescent solitude was drastically impacted by the COVID-19 pandemic. As solitude is crucial for adolescent development through its association with both positive and negative developmental outcomes, it is critical to understand how adolescents' daily-life solitary experiences changed as a result of the pandemic.

METHODS

Using three waves of Experience Sampling Method data from a longitudinal study, we compared adolescents' daily-life solitary experiences in the early (nT1=100; MAge=16.1; SDAge=1.9; 93% girls) and mid-pandemic (nT2=204; MAge=16.5; SDAge=2.0; 79% girls) to their pre-pandemic experiences.

RESULTS

We found that adolescents with lower levels of pre-pandemic social support and social skills reported wanting to be alone less and feeling like an outsider more at both time points during the pandemic. In the mid-pandemic wave, adolescents with higher levels of pre-pandemic social support and social skills reported decreases in positive affect compared to the pre-pandemic wave.

CONCLUSION

This study shows that adolescents' daily-life solitary experiences worsened throughout the COVID-19 pandemic. There should be continued concern for the wellbeing of all adolescents, not only those already at risk, as effects of the pandemic on mental health might only manifest later.

Unsociability and Psychological and School Adjustment in Chinese Children: The Moderating Effects of Peer Group Cultural Orientations

This study examined the moderating effects of cultural orientations of peer groups on the relations between unsociability and psychological and school adjustment in Chinese children. Participants included 1,092 students (527 boys, M age = 12.21 years) in the sixth grade in elementary schools. Data on individualistic and collectivistic cultural orientations, unsociability, and adjustment were obtained from multiple sources including peer nominations, teacher ratings, self-reports, and school records. Using the Social Cognitive Map method, 193 peer groups were identified. Among the results, unsociability was negatively associated with peer preference and academic achievement in groups low on individualistic orientation but not in groups high on individualistic orientation. Unsociability was also negatively associated with peer preference more strongly in groups with higher scores of collectivistic orientation. The results suggested that, in general, unsociable children performed better in social and academical areas in more individualistically oriented groups and less collectivistically oriented groups. The cultural context of peer groups may play a significant role in shaping social and school adjustment of unsociable children.

Shyness and Psychological Maladjustment in Chinese Adolescents: Selection and Influence Processes in Friendship Networks

Few studies have been conducted to examine the role shyness plays in friendship selection and influences processes, particularly how befriending shy peers affects individual's psychological adjustment. To address these gaps, this study investigated the selection, de-selection, same behavior influence effects of shyness in the friendship network in Chinese adolescents using the longitudinal social network analysis. It also explored the possible pathways that transmit indirect influences of friends' shyness to individual's psychological maladjustments (i.e., loneliness and depressive symptoms). A sample of adolescents (N = 1254, 48.4% girls, M_age = 13.20 years at Time 1) were followed for three years in middle schools. The results showed that adolescents tended to befriend those who had similar shyness level during T1-T2 interval, but the friendships between shy friends were more likely to terminate during T2-T3 interval. Moreover, adolescents were found to become more similar with their friends in shyness over time. The study also found that friends' shyness at T1 would influence individual's loneliness at T3 via 1) increasing friends' loneliness at T2 or 2) increasing individual's shyness level at T2. Those two pathways, however, were not found for depressive symptoms. These findings indicate that shyness plays an important role in the friendship formation and dissolution and befriending shy peers may have implications for adolescents' development of shyness and loneliness.

Fuzzy cognitive maps in systems risk analysis: a comprehensive review

Fuzzy cognitive maps (FCMs) have been widely applied to analyze complex, causal-based systems in terms of modeling, decision making, analysis, prediction, classification, etc. This study reviews the applications and trends of FCMs in the field of systems risk analysis to the end of August 2020. To this end, the concepts of failure, accident, incident, hazard, risk, error, and fault are focused in the context of the conventional risks of the systems. After reviewing risk-based articles, a bibliographic study of the reviewed articles was carried out. The survey indicated that the main applications of FCMs in the systems risk field were in management sciences, engineering sciences and industrial applications, and medical and biological sciences. A general trend for potential FCMs’ applications in the systems risk field is provided by discussing the results obtained from different parts of the survey study.

Affiliation with depressive peer groups and social and school adjustment in Chinese adolescents

The purpose of the present study was to examine the role of depressive peer group context in individual social and school adjustment in a sample of 1,430 Chinese adolescents (672 boys, mean age = 15.43 years) from middle (n = 430) and high (n = 1000) schools. Peer groups were identified using the Social Cognitive Map technique. One-year longitudinal data on depression and social and school adjustment were obtained from self-reports, peer nominations, teacher ratings, and school records. Multilevel analyses showed that group-level depression positively predicted later individual depression. Moreover, group-level depression negatively predicted later social competence, peer preference, school competence, and academic achievement, and it positively predicted later peer victimization and learning problems. The results suggest that affiliation with more depressive peer groups contributes to more psychological, social, and school adjustment problems in a cascading manner among Chinese adolescents.
