Oppositional Defiant Disorder: What You Should Know

Last update: 07 November, 2019

Oppositional Defiant Disorder (ODD) involves antisocial behavior that leads to hostility and disobedience. As the name suggests, children with ODD are defiant and uncooperative with authority figures. Children usually develop oppositional defiant disorder around the age of eight.

If children have a defiant attitude for six months or more, they could have ODD. It’s important to consult a psychologist to get an accurate diagnosis.

Oppositional defiant disorder can be seriously detrimental to children’s development. It makes it very difficult to get along well at home, at school, or in any other social environment.

It’s important to mention that there are certain factors that increase a child’s risk of developing ODD. For example, many more boys than girls are diagnosed with the disorder.

Risk factors for developing oppositional defiant disorder

  • Being male.
  • Family history of drug addiction and disorders like ADHD, among others.
  • History of negligence or abuse.
  • Violent behavior, unable to maintain discipline.
  • Growing up surrounded by conflict and stress.
Oppositional Defiant Disorder: What You Should Know

While experts aren’t sure about the causes of ODD, they believe that hereditary and environmental factors are the most likely culprits. Some other possible causes are:

Biological factors

Many children with oppositional defiant disorder have at least one family member with a mood disorder.

An imbalance in certain chemical substances in the brain can affect behavior. Consequently, researchers believe that changes in serotonin levels could trigger ODD.

The inability to manage emotions and control impulses can also contribute to violent and hostile behavior towards other people.

Environmental factors

The environment where children spend most of their time is a key factor in the development of any kind of disorder. Children, just like everyone else, are directly affected by their context. Problems in their immediate surroundings can lead to disruptive behavior.

The environmental factors that are most relevant are:

  • Frequently changing schools.
  • Constantly changing caregivers.
  • Parents’ divorce.
  • Instability at home.

Symptoms of oppositional defiant disorder

It isn’t always easy to tell the difference between a child with a strong personality and a child with ODD. Nevertheless, there are some symptoms that can help you identify the disorder.

Children with ODD invariably act out at home, but they might not show any signs of the disorder at school. Each child is different. Here are some of the most common symptoms:

  • Low self-esteem.
  • Problems with concentration.
  • Generalized aggressiveness.
  • Deliberately bothering other people.
  • No impulse control.
  • Feelings of resentment and vengeful behavior.
  • Resistance to following rules or requests.
  • Children with ODD don’t like working in a group, so they tend to isolate themselves.
  • Rebelliousness, defies authority figures, no respect for established boundaries.
  • Blaming others for their mistakes or bad behavior.
  • Always irritable or in a bad mood, easily frustrated.
  • Deliberate and constant verbal abuse. Uses a vocabulary full of bad words, isn’t afraid to say them to anyone in order to cause harm.

Effects of ODD

If ODD isn’t treated in time, these problems will follow the child into adulthood. In extreme cases, the individual with ODD could end up incapacitated, and completely unable to cope in social situations.

Adults with untreated ODD are also more likely to become addicted to drugs, which makes the problem even worse.

At school, children with untreated ODD often fail and drop out. What’s more, they have trouble forming relationships with the other students, so they end up forming unhealthy friendships elsewhere.

ODD also has a profound impact on interpersonal relationships and family life. Over time, the characteristic antisocial and hostile behavior of oppositional defiant disorder makes it nearly impossible for people with this condition to maintain relationships.

In conclusion, it’s crucial to diagnose and treat ODD in children as soon as possible. The sooner the problem is identified, the better. With the proper treatment and support, children with ODD can learn to cope and go on to live full and happy lives.
