How to tell the difference between ODD and conduct disorder (CD)

Oppositional defiant disorder (ODD) and conduct disorder (CD) are the most common behavior disorders in children and adolescents. These disorders are characterized by irritability, aggression, and defiance. These behaviors can be a challenge for families, caretakers, and teachers.

Though they may have shared roots and overlapping symptoms, ODD and CD aren’t the same. Understanding the differences in ODD vs. conduct disorder can help guide the right support. Each condition requires a different approach for the most effective care.

Navigating ODD and conduct disorder can feel difficult for children and their families, but there’s hope. With the right resources and treatment, it’s possible to help kids regulate their emotions and build positive relationships.

Telling the difference between CD and ODD

Though often grouped under the same umbrella of disruptive behavior disorders, ODD and CD have some key distinctions. These include symptoms, age of onset, and risk factors.

• Symptoms: People with ODD or conduct disorder show signs of aggression, defiance, irritability, risky behavior, and emotional dysregulation. Defiance is often associated with ODD, as well as angry and irritable moods. CD, on the other hand, is more severe and may put others at risk. Behaviors among people with CD include bullying, theft, destruction of property, or violence toward other people or animals.

• Age of onset: Symptoms of ODD show up in the preschool years — most often before age eight. If untreated, ODD can lead to CD, which is typically diagnosed later in childhood. There are two primary types of CD based on age of onset: childhood-onset, which begins before age 10, and adolescent-onset, which starts after age 10.

• Risk factors: While family environment can play a role in ODD, this condition often stems from internal factors like temperament and coexisting conditions like attention-deficit hyperactive disorder (ADHD) and anxiety. While genetic and biological factors can play a role in whether a child develops CD, external factors heavily contribute to the development of CD, including trauma, abuse, peer influence, and other social factors.

Why ODD and CD can seem similar

There are many similarities between conduct disorder and ODD, which can make them hard to tell apart.  Both involve patterns of disruptive behavior and difficulty managing emotions.

Behavioral patterns

Children with ODD or CD often display patterns of disruptive and noncompliant behaviors. They might talk back to teachers, refuse to follow rules, or argue with authority figures. This goes beyond typical childhood defiance that may be common as children learn to explore and express themselves. With ODD or CD, these behaviors are more intense and last longer, making it hard to follow social norms like listening to others or taking turns.

This can significantly impact kids’ day-to-day life, whether at home or in school. It can make it harder for them to learn in a traditional classroom setting or build relationships with their peers.

Emotional dysregulation

Additionally, kids with ODD or CD have difficulty in managing their emotions. This may result in frequent emotional outbursts and make it hard for them to cope with intense feelings like anger, frustration, or disappointment. They may experience a disproportionate response to small setbacks. This means that being told “no” or not getting their way can trigger an emotional outburst.

The symptoms of ODD and CD can make kids feel isolated. They might feel like no one understands them or like they’re constantly getting in trouble. If left unaddressed, ODD and CD can lead to more serious issues like unhealthy substance use or criminal activity. Early treatment is essential.

Can you have both conduct disorder and ODD?

It’s possible to have both oppositional defiant disorder (ODD) and conduct disorder. They’re related conditions, but not the same. ODD is characterized by ongoing defiance and irritability, while conduct disorder involves more serious rule-breaking or harmful behavior.

Sometimes ODD comes first, but it doesn’t always turn into conduct disorder. When both are present, behaviors can feel more intense and harder to manage.

The good news is that support can make a big difference. With the right help, many kids learn better ways to manage emotions and behavior over time.

Treatment for ODD or CD

The current diagnostic criteria for CD and ODD considers the number of symptoms, not the severity of each symptom. This can make it easy to misdiagnose children with mild or borderline ODD and CD. With that in mind, it’s important for a diagnosis to consider symptom severity, to avoid children being misdiagnosed or having their disruptive actions considered as “just a phase.”

Once a child is diagnosed, treatment for ODD and conduct disorder can begin. There’s no cure for ODD and CD, but there are many ways to manage and treat symptoms. This can include a combination of therapy and lifestyle changes.

• Cognitive behavioral therapy (CBT): CBT is one of the most widely used types of talk therapy. In CBT, you learn to identify negative thoughts that may be fueling unhelpful behaviors. Then, you’re guided into replacing those thoughts with healthy beliefs. Learning how to navigate negative thoughts and find ways to express yourself in healthy ways can help kids manage the symptoms of ODD or CD.

• Parent management training (PMT): For parents of kids with ODD or CD, it’s crucial to learn how to manage their child’s behaviors while providing a safe and supportive environment. PMT gives parents strategies for managing defiant behaviors, improving their relationship with their child and fostering positive family dynamics.

• Multisystemic therapy (MST): MST is often used to treat conduct disorder, as it addresses the complex external factors that influence CD. MST focuses on the broader environment that a child lives in. It involves working with the child, family, school, and community to create positive change.

• Medication management: Medication is typically not the first line of treatment for disruptive behavioral disorders. However, when other conditions, like ADHD, occur alongside ODD or CDD, medication can be a helpful part of a comprehensive treatment. Work with your provider to determine if medication is right for you or your child.

Clinician’s take

In my experience, ODD shows up as arguing, defiance, and trouble with authority. Conduct disorder is more serious. It includes behaviors like aggression, lying, or breaking rules in ways that can harm others. With the right support, symptoms of both conditions can improve. Early intervention can make a big difference.
