What kind of actions result in psychological issues in teens?

Good list from @basilfawlty89. I would add: parents who are overly controlling, don't create space for a child to explore their own ideas or emotions... are more highly likely to see delinquent tendencies in 11-15 year olds. This is based on Scottish research.

So parents who think the goal is control have no understanding of their role. Children may become rebellious or passive aggressive because their emotions have no way to go, and the only clear path they see is resistance.

By the time they are in late teens they need to have processed their emotions, thinking, values etc and begin to make responsible decisions, feeling as though their parents are supportive, listen, care, create space... but still provide guidance.
