Promoting Peer Connectedness Through Social-Emotional Learning: Evaluating the Intervention Effect Mechanisms and Implementation Factors of a Social-Emotional Learning Programme for 9 to 12-Year-Olds.

There is little evidence regarding the effect mechanisms of social-emotional learning programs on children's peer relationships. The current study evaluated a novel school-based social-emotional learning program for the first year of secondary school assessing effects on social-emotional skills, peer connectedness, happiness, student and teacher classroom climate. The sample included 19 intervention classrooms (n = 399) and 16 waitlist-control classrooms (n = 281), with a mean age of 10.34 (SD = 0.76) and 48.8% girls. The main intervention effect analysis followed a per-protocol approach and was thus conducted with eight classes that finished all sessions (n = 195) and the control group classes (n = 281). It was further hypothesized that increases in social-emotional skills would predict peer connectedness and class climate increases, which would predict happiness. Results indicated significant intervention effects for social skills, peer connectedness and happiness. Classroom climate declined for both groups, seemingly affected by the school transition. Hypothesized relationships between target variables were partly supported with significant effects of social-emotional skills on connectedness and significant effects of peer connectedness on happiness for children reporting connectedness decreases. Additional analyses were conducted including all classrooms to compare the intervention's effectiveness across different implementation progress groups. Significant group differences were found, indicating that implementation aspects impact intervention outcomes. The findings indicate that universal, school-based social-emotional leaning programs are effective approaches to support peer relationships in the context of the school transition. However, more implementation support seems to be needed to ensure best-practice delivery and achieve maximal intervention effectiveness.

Early adolescents' perspectives on factors that facilitate and hinder friendship development with peers at the time of school transition.

Supportive peer relationships are fundamental for mental health and well-being. Hence, peers and friends are a valuable resource, especially at the time of transition from primary to secondary school. Yet, current literature lacks both novel approaches to studying friendship development and how to involve early adolescents in research that is being conducted about them. Within the present study we used novel participatory research methods involving early adolescents who were active in the analysis of their own generated data. We aimed to better understand their perspectives on factors that facilitate and hinder friendship development with peers during the time of school transition between primary and secondary schools. A total of 916 pupils (Mage = 10.44 years, range = 9-16) participated in 54 participatory workshops that were conducted in Austria. We used reflexive thematic analysis to analyze qualitative data from portions of a large series of participatory workshop activities. Moreover, we actively involved participants in the analysis of their own generated data. Themes were structured into personal, interpersonal, and external factors. We found that early adolescents valued kind peers that (a) give them a feeling of safety, (b) show supportive and empathic actions, (c) manage conflicts, (d) avoid negative behavior, (e) spend time with them, and (f) communicate in the offline and online environments. Although shared norms of behavior can support friendship development, friendship jealousy and tolerating bigger friendship groups were identified as important potential barriers. Additionally, external factors (i.e., given circumstances), such as similarities, physical proximity, and duration of acquaintance were included in our data but were perceived as less important by early adolescents. Our results supplement the existing peer relationship literature by showing which factors early adolescents themselves chose as most relevant for friendship development. We conclude with a discussion regarding the implications for school psychology practice and future research.
