Boys are diagnosed with Conduct-Dissocial Disorder (ICD-11 6C91) more often than girls — roughly two to four times as often in childhood — but girls develop it too, often showing it differently and being identified later. Sex is a population pattern, not a prediction for any one child; persistent, severe behaviour across settings is what warrants a developmental check, formed only by a Pinnacle clinician.

*Yes — boys are diagnosed more often, but the difference is smaller than many parents expect, and it never changes what your child needs.*

## In short
Conduct-Dissocial Disorder (ICD-11 **6C91**) is identified more frequently in boys than in girls — commonly cited at roughly two to four times as often in childhood. But this is a pattern across populations, **not** a prediction for any one child. Girls do develop it too, often showing it differently, so it can be missed. What matters far more than your child's sex is *what they are doing, how often, and whether it is getting in the way of family, school and friendships.*

## Why the difference — and why it matters less than you think
The higher rate in boys partly reflects how the condition tends to appear: boys more often show outward, physical defiance and aggression that adults notice quickly. Girls more often show relational patterns — manipulating friendships, deceitfulness, running away — which are easier to overlook, meaning some girls are simply identified later, not less affected.

A few points worth holding onto:
- **Sex is a statistic, not a verdict.** A boy is not destined to develop this; a girl is not protected from it.
- **Behaviour is the signal, not gender.** Persistent aggression, serious rule-breaking, cruelty or destructiveness lasting many months — across home *and* school — is what warrants a closer look.
- **Context shapes behaviour.** Stress, learning difficulties, unmet communication needs and difficult environments all feed conduct patterns, and all respond to the right support.

## When to seek a developmental check
Reach out if challenging behaviour is **frequent, severe, and spans more than one setting** for six months or more, or if it is harming your child's relationships or learning — regardless of whether your child is a boy or a girl. Earlier support means gentler, more effective help.

## The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an online list or a child's sex. We look at the whole child: communication, emotional regulation, environment and strengths. Begin with a [developmental check](/), understand the measure behind our plans through [the AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated), and explore how [behavioural therapy](/behavioural-therapy) builds calmer, more confident days.

## Trusted sources
WHO ICD-11 classification of Conduct-Dissocial Disorder (6C91); American Academy of Pediatrics guidance on disruptive behaviour in children; NICE guidance on antisocial behaviour and conduct disorders.

**Next step —** Worried about your child's behaviour, boy or girl? [Book a developmental check with a Pinnacle clinician](/).

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
