1) What it is
Conduct Disorder is a mental health condition in children and teenagers where there is a repeated and persistent pattern of behaviour that breaks rules and/or violates the rights of other people.
It goes beyond occasional misbehaviour or being “naughty.” Conduct Disorder is usually diagnosed when behaviours are:
- ongoing and frequent
- happening across multiple settings (home, school, community)
- causing serious disruption or harm
Examples can include:
- aggression toward people or animals
- damaging property
- lying or stealing
- serious rule-breaking
Conduct Disorder is treatable, and support usually involves family-based and behavioural interventions.
2) What it feels like (real-life examples)
From the young person’s perspective
Some young people may feel:
- constantly angry or on edge
- misunderstood or judged
- ashamed but acting tough to hide it
- like rules are unfair or don’t matter
- numb or disconnected
- overwhelmed underneath the behaviour
They may say:
- “Everyone is against me.”
- “I’m always in trouble.”
- “I can’t control it when I’m angry.”
- “People push me and I react.”
From the parent or carer’s perspective
Parents and carers often feel:
- exhausted and overwhelmed
- frightened for safety
- stuck in constant conflict
- worried about exclusion from school
- anxious about police or social services involvement
3) Common signs & symptoms
Patterns can vary, but common signs include:
Behaviour patterns
- frequent aggression (fights, bullying, threats)
- cruelty to animals (in some cases)
- damaging property (vandalism, fire-setting)
- stealing and lying
- serious rule-breaking, such as:
- staying out late
- running away
- truancy
- repeated boundary violations
Emotional signs
- extreme irritability or anger
- low frustration tolerance
- difficulty showing empathy (not always)
- defensiveness and blaming others
- shame hidden beneath hostility
School and social impact
- repeated punishment or exclusion
- conflict with authority figures
- difficulty maintaining friendships
- involvement in risky peer groups
Some young people show callous-unemotional traits (appearing cold or uncaring), but this is not true for everyone.
4) What causes it / risk factors
Conduct Disorder usually develops through a combination of factors rather than one single cause.
Common risk factors include:
- trauma, abuse, or neglect
- unstable or unsafe home environments
- inconsistent boundaries or lack of structure
- exposure to violence
- bullying or social rejection
- learning difficulties or neurodiversity
- untreated ADHD (often overlapping)
- parental stress, mental illness, or substance misuse
- poverty, housing instability, or community stress
Difficult behaviour is often communication of unmet needs:
“I don’t feel safe, heard, or in control — so my behaviour becomes the message.”
Support is most effective when it includes family and environment, not just the child.
5) Triggers (what can make it worse)
Common triggers include:
- criticism, shaming, or rejection
- being told “no” or losing control
- sensory overload or frustration
- conflict at home or school
- major transitions (moving house, school changes)
- hunger, tiredness, or poor sleep
- learning difficulties and academic stress
- peer pressure
- chaotic routines or inconsistent rules
Many incidents occur when the young person feels:
- trapped
- disrespected
- overwhelmed
- powerless
6) What helps right now (fast relief tools)
These are de-escalation strategies for parents and carers.
Lower intensity
- speak slowly and quietly
- use fewer words
- keep your body language calm
Avoid arguing during escalation
When emotions are high, reasoning won’t work. Try:
- “I can see you’re angry. We’ll talk when it’s calmer.”
Offer two safe choices
This restores a sense of control:
- “You can sit here quietly or go to your room — you choose.”
Prioritise safety
If there is risk:
- move others to safety
- keep physical distance
- seek external help if needed
Repair after the incident
When calm:
- name what happened
- explain the impact
- reconnect before consequences
7) Longer-term self-help strategies
This is primarily about family systems and skills, not the child “trying harder.”
1) Consistent routines and boundaries
Children benefit from:
- predictable structure
- clear expectations
- calm, consistent consequences
2) Reduce shame, increase connection
Shame fuels aggression. Connection reduces defensiveness.
A key message:
“I don’t like the behaviour, but I still care about you.”
3) Teach emotional regulation skills
Teach these outside of crisis moments:
- breathing techniques
- anger scales (1–10)
- safe exit strategies
- physical ways to release energy
4) Reinforce positive behaviour
Notice and reinforce:
- cooperation
- calm moments
- small improvements
This is more effective than constant punishment.
5) Work closely with school
Ask about:
- behaviour plans
- pastoral or SEND support
- mentoring or emotional literacy programmes
8) Treatment options (what usually helps)
Conduct Disorder responds best to family-based and systemic support.
Common approaches include:
- parent training programmes
- family therapy
- behavioural interventions
- coordinated multi-agency support
- treatment for co-existing conditions such as ADHD or trauma
Evidence-based guidance supports structured family and behavioural interventions.
9) Medication overview (plain-English)
There is no medication that directly treats Conduct Disorder itself.
Medication may be considered if there are co-existing conditions such as:
- ADHD
- severe anxiety
- depression
- mood disorders
This is always assessed by a specialist.
10) Work, relationships & daily life tips
For parents and carers
- pick your battles
- use calm consequences, not shouting
- prioritise safety and repair
- keep routines predictable
- seek support for yourself
For school life
Helpful supports include:
- clear behaviour plans
- safe “time out” spaces
- mentoring
- emotional skills programmes
For the young person
Focus on:
- building trust with safe adults
- identity beyond “the bad kid”
- strengths, interests, and goals
11) When to seek urgent help
Seek urgent support if:
- there is serious violence
- weapons are involved or threatened
- the young person is out of control and unsafe
- siblings or parents are at risk
- there is risk of criminal exploitation or gangs
- the young person is self-harming or suicidal
If anyone is in immediate danger, contact emergency services.
