Conduct-Dissocial Disorder
What is Conduct-Dissocial Disorder?
Conduct-Dissocial Disorder (ICD-11 6C91) is a repetitive, persistent pattern of behaviour that violates others' basic rights or major age-appropriate social rules — recurring aggression, destruction, deceit or serious rule-breaking lasting around 12 months and disrupting daily life. It is recognised in children and adolescents and is distinct from ordinary defiance or a short phase. Behaviour often reflects underlying drivers such as trauma, learning needs or co-occurring conditions, so compassionate, whole-child assessment matters.
When defiance hardens into a pattern that harms others or breaks the rules that keep a child safe, there is a name — and a path forward.
In short
Conduct-Dissocial Disorder (ICD-11 6C91) is a repetitive, persistent pattern of behaviour in which the basic rights of others, or major age-appropriate social rules, are violated. This goes well beyond ordinary mischief or a difficult phase — it means recurring aggression, deliberate destruction, deceit or serious rule-breaking that lasts months and disrupts home, school or community life. It is recognised in children and adolescents, and importantly it is understandable and supportable, not a verdict on your child's character.What the pattern looks like
In ICD-11, the picture includes sustained behaviours such as physical aggression towards people or animals, bullying or intimidation, destroying property, lying or stealing, and serious violation of rules (for example, persistent truancy or running away). For a clinician to consider this label, the behaviours must be repetitive and persistent over a meaningful period (around 12 months), clearly beyond what's expected for the child's age, and causing real difficulty in everyday settings — not a single incident or a short-lived reaction to stress.Context matters enormously. Many children show these behaviours in response to trauma, instability, unmet learning needs, communication frustration, or co-occurring conditions such as ADHD. A careful assessment looks behind the behaviour, not just at it. That is why early, compassionate evaluation matters: the earlier the drivers are understood, the more responsive support can be.
When to seek support
Reach out for a developmental review if defiant, aggressive or rule-breaking behaviour is frequent, escalating, harming others, or persisting across months and settings. Sudden behaviour change, self-harm, or risk to safety warrants prompt medical attention rather than waiting.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app, a checklist or a single conversation. Our approach explores the whole child through behavioural therapy and family-centred support, individualised on the conduct-dissocial disorder profile so that the reasons behind behaviour guide the plan.Trusted sources

What to watch
Frequent or escalating physical aggression, bullying, destroying property, persistent lying or stealing, and serious rule-breaking such as truancy or running away — lasting months and occurring across home, school and community, beyond what's expected for the child's age.
Try this at home
Respond to repeated rule-breaking with calm, consistent and predictable routines rather than escalating consequences — and keep a simple note of what happens before and after incidents, as these patterns help a clinician understand the drivers.

Frequently asked
Is Conduct-Dissocial Disorder the same as a child being naughty or going through a phase?
No. Ordinary mischief, testing limits and difficult phases are a normal part of growing up. Conduct-Dissocial Disorder describes a repetitive, persistent pattern of behaviour — lasting around 12 months — that seriously violates others' rights or major social rules and disrupts daily life across settings. A clinician distinguishes the two carefully.
What causes this kind of behaviour in a child?
There is rarely one cause. Behaviour can reflect trauma, family or environmental stress, unmet learning or communication needs, and co-occurring conditions such as ADHD. A good assessment looks behind the behaviour to understand its drivers, which then guide support.
Can it be helped?
Yes. Early, compassionate, family-centred support — including behavioural therapy and structured, consistent routines — can make a real difference. The earlier the drivers are understood, the more responsive the plan can be.
How is it assessed at Pinnacle Blooms Network?
Through a clinician-administered structured assessment, the AbilityScore®, alongside developmental and behavioural review at a Pinnacle Blooms Network centre. Any diagnosis is formed only by a qualified clinician, never from an app or checklist.
