Adolescence is a period of major change. Teenagers seek more autonomy, shape their identity, are more influenced by relationships with peers and often test limits — their own and those of the adults around them.
Taking some risks can be part of this developmental journey. However, when
repeated aggressive, dangerous or delinquent behaviours appear, we need to look for what may lie behind them, rather than simply labelling the teenager as “difficult” or “delinquent”.
Adolescent delinquency is a complex phenomenon. It has no single cause and is rarely explained by one factor alone. Individual characteristics, family and social circumstances, school difficulties, peer relationships, experiences of violence or bullying, substance use and mental health problems can all interact.
That is why effective management starts with
understanding and prevention rather than assigning blame.
The family: presence, communication and boundaries
In adolescence, the parent–child relationship changes. Teenagers need more personal space and autonomy, but this does not mean they stop needing their parents’ presence.
Positive parental involvement does not mean constant control. It means that parents know what is happening in their child’s life, take an interest in their friends and activities, notice changes in behaviour and remain available to talk.
At the same time, teenagers still need clear and consistent boundaries. Boundaries work best when they are understandable, age-appropriate, applied fairly consistently and gradually leave more room for responsibility and independence.
The goal is not a teenager who obeys everything. It is a young person who gradually learns to make choices, anticipate consequences and take responsibility for their actions.
Listen before judging
Communicating with a teenager is not always easy. They may answer in single words, withdraw, get angry or reject adults’ advice.
This does not mean parents should stop trying.
Often, listening needs to come before advice. Questions such as “What happened?”, “How do you see it?” or “Is anything bothering you lately?” can open a dialogue far more than an interrogation or a lecture.
Teenagers don’t need their parents to agree with every choice they make. But they do need to know that they can come back to them even when they have made a mistake.
This does not cancel the consequences of a behaviour. But it creates the conditions for the family to deal with it.
The role of the school
School is one of the most important settings in a teenager’s daily life. An environment where students feel they belong, are treated with respect and can turn to an adult when they are struggling has significant protective value.
At the same time, changes such as a sudden drop in school performance, frequent absences, isolation, repeated conflicts or marked aggression may indicate that a teenager needs more attention.
None of these behaviours on its own means a child will become delinquent. But it can be a reason for
early assessment and support.
When does a change in behaviour need closer attention?
Changes in mood and behaviour are common in adolescence. What matters most is their intensity, their duration and how far they affect the functioning and safety of the teenager or the people around them.
Particular attention is needed when there is persistent aggression or violent behaviour, repeated risky acts, significant withdrawal from school or family, substance use, serious changes in sleep or mood, or behaviours that put the teenager or others at risk.
Behind a difficult behaviour there may be an equally difficult emotion or a situation the teenager does not know how to handle.
So the question is not only “How do we stop this behaviour?” but also “What is this behaviour trying to tell us?”
The pediatrician and the adolescent’s psychosocial health
Pediatric care in adolescence is not only about height, weight, vaccines or physical symptoms.
The primary care pediatrician can follow the child’s development as a whole and discuss issues such as mood, school, relationships, sleep, substance use, sexual health, the internet, bullying and behaviours that may put the teenager at risk.
It is especially important to make room for the teenager themselves to speak and feel heard.
The pediatrician does not replace a mental health specialist. But they can be an important first point of recognition and support, assess whether further evaluation is needed and, when necessary, refer to a child psychiatrist, psychologist or other appropriate service.
In more complex cases, cooperation between the family, the pediatrician, the school and mental health professionals can be decisive.
Positive parental involvement: neither absence nor suffocating control
Being a positive presence in a teenager’s life can mean something very simple:
Showing interest without interrogating. Listening without always rushing to offer a solution. Knowing where your child is and who they spend time with, in an age-appropriate way. Setting boundaries and explaining why they exist. Recognising effort and not only results. Leaving room for independence while remaining available when the teenager needs you.
And perhaps the hardest of all: keeping the relationship going even when you need to disagree with the behaviour.
We are not looking for “someone to blame” — we are looking for what the teenager needs
A teenager’s delinquent behaviour should not automatically become their identity.
A teenager who breaks a rule, gets involved in a conflict or makes a seriously wrong choice is not necessarily a “delinquent teenager”. We need to assess the behaviour, the context in which it occurred, whether it is repeated, its consequences and the factors that may be feeding it.
The family, the school and health professionals have different but complementary roles. Early communication between them can help a difficulty to be recognised before it develops into a bigger problem.
Standing firmly by the teenager
Adolescence requires a delicate balance: freedom and boundaries, trust and supervision, independence and presence.
Parents don’t need to be perfect, and teenagers don’t need to be cooperative all the time.
But there needs to be a relationship secure enough to withstand disagreements, mistakes and difficult periods.
Because prevention does not start when delinquency appears. It starts much earlier — with relationship, communication, consistent boundaries and early recognition when a teenager is struggling.
