Physical aggression was defined as conduct disorder (i.e. violating the basic rights of others, disregarding age‑appropriate social norms) or physical aggression (e.g., kicking or hitting other children).
Indirect aggression is defined as non‑physical behaviour to cause harm to others. It includes behaviours such as gossiping and social exclusion.
High/low behaviour was determined by the 10th/90th percentile cutpoints (as appropriate).
