Preteens are undergoing social conflicts since they are trying to please parents, friends and teachers all at the same time. Some of this turmoil may be expressed through increased anger and rebellion directed toward parents and other adults. Preteen anger usually occurs when children encounter some situation that they cannot control or which does not come out as they expected. They are angered and frustrated by things that upset their routine or their plan. Their anger is self-centered.
Adults are a common target for anger as they seek to set and enforce limits.
Total control usually leads to open rebellion. This age group is likely to express anger verbally with sarcastic remarks and sulkiness. They may also fight, kick, hit and slam doors. Preteens need to be shown socially acceptable ways to express and vent their anger. Whereas parents would like angry children to think and speak rationally, in lowered tones with controlled feelings, some do not always display such control themselves.
