The developmental relation between aggressive behaviour and prosocial behaviour: A 5-year longitudinal study.

BACKGROUND: Past research has shown links between both children's aggressive behaviour and a lack of prosocial behaviour to later maladaptation. Both types of behaviours have also been identified as crucial in children's social and emotional development and later (mal)adaptation. However, little is known about the way they predict each other over time. METHODS: We utilised a large, ethnically diverse, longitudinal population sample of girls and boys (N = 1,334) to examine the bidirectional cross-lagged links between aggressive and prosocial domains of behaviour from age seven to eleven. Teacher, parent and child self-reports were utilised to assess aggressive behaviour and prosocial behaviour. RESULTS: The results revealed that aggressive behaviour measured one year predicted decreases in prosocial behaviour in the following year. Conversely, prosocial behaviour did not predict changes in aggressive behaviour in the subsequent year. Furthermore, peer difficulties were examined and found to be an important mediator of the link between aggressive and prosocial behaviour. Specifically, peer difficulties mediated the links between aggressive behaviour and prosocial behaviour one year later, particularly during the first three years of school attendance. CONCLUSIONS: Implications of the findings for the design of intervention strategies to reduce children's aggressive behaviour are discussed

The impact of school exclusion in childhood on health and well-being outcomes in adulthood:Estimating causal effects using inverse probability of treatment weighting

BackgroundPrevious evidence has suggested a strong association between school exclusion and health outcomes. However, as health risks are themselves related to the risk of experiencing a school exclusion, it has been challenging to determine the extent to which school exclusion impacts later health outcomes, as opposed to reflecting a marker for pre-existing risks.AimThe aim of the current study was to address this challenge in estimating the medium-to-long-term impact of school exclusion of health and well-being outcomes.MethodsTo this end, we used an inverse propensity weighting approach in the Next Steps data set (N = 6534, from wave 1, 2014, to wave 8, 2015).ResultsWe found that after weighting for propensity of treatment scores estimated based on a wide range of factors, including previous health indicators, there was a significant effect of school exclusion on a wide range of health and well-being outcomes.DiscussionThese results provide some of the most robust evidence to date that school exclusion harms long-term health outcomes.ConclusionThe findings suggest that policies should aim to reduce exclusion and ensure access to preventative health support for those who experience a school exclusion

The role of student-teacher relationships in the association between negative parenting practices and emotion dynamics:Combining longitudinal and ecological momentary assessment data

Emotion dysregulation is increasingly implicated as a transdiagnostic risk factor in the etiology of mental health problems. This project aimed to explore the links between emotion regulation, negative parenting and student-teacher relationships using longitudinal and ecologically valid data. A sample of n = 209 young people enrolled in the 'Decades-to-Minutes' (D2M) study, based in Zurich, Switzerland, provided data from the ages of 7-20 via parent- and self-report questionnaires and ecological momentary assessment. Data were analyzed using Dynamic Structural Equation Modeling (DSEM). Worse student-teacher relationships predicted increased negative affectivity and emotional lability. Negative parenting practices predicted emotional lability only via their impact on student-teacher relationships. The findings point to worse student-teacher relationships as risk factors in the socioemotional development of children and young people
