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.

Brief report: The impact of attention deficit hyperactivity disorder (ADHD) symptoms on academic performance in an adolescent community sample.

Less is understood about the relationship between ADHD symptoms and academic performance in adolescents than the relationship in younger children. As such, the aim of the present study was to investigate the prospective relationship between ADHD symptoms and academic performance in a community adolescent sample. Three hundred and twenty-four participants, aged 15 and 16, in their final year of compulsory education, completed measures of ADHD, anxiety, depression, and motivation, and a test of general cognitive ability. Participants were also asked for permission for their academic grades to be viewed on a later occasion (approximately 6 months later). In regression analyses, ADHD symptoms were the most significant independent psychopathological predictor of academic performance, and were almost as significant as motivation and cognitive ability. The results suggest that adolescents with more ADHD symptoms are likely to encounter greater academic difficulties.
