Many children with Oppositional Defiant Disorder (ODD) have other mental health problems like depression, anxiety, or Attention Deficit/Hyperactivity Disorder (AD/HD). Their difficult behaviours are often a reaction to the symptoms of these conditions.
Children with ODD are more likely than other children to have a family history of behavior problems, mood problems, or substance abuse. Sometimes if care-giving is poor, supervision is lacking, or there is family discord or exposure to violence, children will respond by developing the symptoms of ODD. Having a mother with untreated depression also makes children more likely to have ODD. Both ODD and CD are associated with harsh parenting practices.
