What is Conduct Disorder?

According to DSM-IV criteria, conduct disorder may be diagnosed when a child seriously misbehaves with aggressive or nonaggressive behaviors against people, animals or property that may be characterized as belligerent, destructive, threatening, physically cruel, deceitful, disobedient, or dishonest. This may include stealing, intentional injury, and forced sexual activity. Keep in mind that this behavior disorder consists of a pattern of severe, repetitive acting-out behavior and not of an isolated incident here and there.

As stated, conduct disorder is a repetitive and persistent pattern of behavior in which the basic rights of others, or major rules and values of society are violated, as shown by the presence of three (or more) of the following behavior patterns in the past 12 months, with at least one behavior pattern present in the past six months:

Aggression to people and animals:
Often bullies, threatens, or intimidates others.
Often initiates physical fights.
Has used a weapon that can cause serious physical harm to others (for example, a bat, brick, broken bottle, knife, gun).
Has been physically cruel to people.
Has been physically cruel to animals.
Has stolen while confronting a victim (for example, mugging, purse snatching, extortion, armed robbery.
Has forced someone into sexual activity.

Destruction of property:
Has deliberately engaged in fire setting with the intention of causing serious damage.
Has deliberately destroyed others' property (other than by fire setting).

Deceitfulness or theft:
Has broken into someone else's house, building, or car.
Often lies to obtain goods or favors or to avoid obligations (in other words, "cons" others)
Has stolen items of nontrivial value without confronting a victim (for example, shoplifting, but without breaking and entering; forgery).

Serious violations of rules:
Often stays out at night despite parental prohibitions, beginning before age 13 years
Has run away from home overnight at least twice while living in parental or parental surrogate home (or once without returning for a lengthy period)
Is often truant from school, beginning before age 13 years

According to DSM-IV, in order to diagnosis conduct disorder in a teen, the disturbance in behavior must be causing significant problems in that person's life, including at school, with friends and family, and on the job. In other words, if a child gets into serious trouble one time, learns from the experience and never does it again, he or she probably does not have a conduct disorder.

Conduct disorder may be diagnosed in an individual 18 years or older if that individual displays some of the behaviors listed above but does not appear to have behaviors normally found in Antisocial Personality Disorder.

According to Merck's Manual, the onset of conduct disorder is usually in late childhood or early adolescence. Conduct disorder appears to be much more common in boys than girls. Children with conduct disorder seem to have an inability to correctly "read" other people, and instead will misunderstand the intentions of others, many times believing that people are threatening them or putting them down, when this is not really the case. They tend to react to these supposed threats or put-downs in an aggressive manner with little show of feeling or remorse. They do not tolerate frustration well. They also tend to generally behave in a reckless manner, without regard for normal safety issues.

Kids with conduct disorder frequently will threaten suicide, and these threats should generally be taken seriously.

Boys with conduct disorder will be more inclined to fight, steal and participate in acts of vandalism, such as fire setting. Girls with conduct disorder are more likely to lie, run away and be involved in severe sexual acting-out behavior, including prostitution. Both boys and girls with conduct disorder are at an extremely high risk of substance abuse along with severe difficulties getting along in school.

What are the signs of Oppositional Defiant Disorder (ODD)?

According to the DSM-IV, if a child's problem behaviors do not meet the criteria for Conduct Disorder, but involve a pattern of defiant, angry, antagonistic, hostile, irritable, or vindictive behavior, Oppositional Defiant Disorder may be diagnosed. These children may blame others for their problems.

Oppositional Defiant Disorder is a pattern of negativistic, hostile, and defiant behavior lasting at least six months, during which four (or more) of the following are present:

Often loses temper.
Often argues with adults.
Often actively defies or refuses to comply with adults' requests or rules.
Often deliberately annoys people.
Often blames others for his or her mistakes or misbehavior.
Is often touchy or easily annoyed by others.
Is often angry and resentful.
Is often spiteful or vindictive.

It is important to note that a counselor or therapist will consider a diagnosis of oppositional defiant disorder only if the behavior occurs more frequently than is typically observed in individuals of comparable age and developmental level. In other words, the problems and conflicts between teens and parents are as old as time itself, and some conflict is normal and inevitable. However, when the parent/child conflict becomes increasingly severe and appears to be spiraling out of control, then ODD might be considered. Also, as teens are growing and learning, they will sometimes do some very ill-advised things that can cause them problems, both legal and in school. However, if this behavior does not repeat itself and is a one-time event, then a behavior disorder is probably not present.

For a diagnosis of ODD to be made, the disturbance in behavior must be causing significant problems in school, in relationships with family and friends, and in the workplace. ODD will not be diagnosed if the the therapist suspects that the teen's behaviors are being directly caused by another psychotic or mood disorder, such as bipolar disorder.

Kids with oppositional defiant disorder will show some of the same behaviors as those listed above for conduct disorder, including being very negative, angry and defiant. However, with ODD, one does not generally see the mean or cruel behavior that is present in conduct disorder, such as cruelty to animals.

How does the therapist find a diagnosis for my teen?

As you can see from the behaviors listed above, there is a large overlap between conduct disorder and oppositional defiant disorder, with similarities in both disorders that include defiance, rebellion against authority, school problems, disobedience, anger and resentment, and bullying of brothers and sisters. In order to differentiate between the two, one of the things a therapist will generally look at is how a teen treats animals. Is he or she mean or cruel to the family pets or kind to them? Another area that is looked at is whether or not there have been legal problems, what those legal problems were, and if they are recurring or one-time events. For example, many young teens experiment with shoplifting and end up getting caught, but this does not mean they have either a conduct disorder or ODD. However, if they keep doing it or their activities turn to more serious stealing behavior, it is probably safe to assume that there is a more serious behavior problem going on. Setting fires and stealing, such as breaking into cars and stealing stereos, are more serious offenses that would generally tend to indicate a conduct disorder rather than oppositional defiant disorder.

To further complicate the process of making a diagnosis, some research is now beginning to show that conduct disorder may be a component of childhood bipolar disorder and there is a possibility that the behaviors attributed to conduct disorder or ODD are perhaps motivated by a mood disorder. Bipolar disorder, formerly known as manic-depressive illness, described in simplest terms is a chemical imbalance in the brain that causes major mood swings, from elation to severe depression, which many times can be helped greatly with the right medication. According to the book, The Bipolar Child, teens with bipolar disorder can experience mood shifts from very elated to very depressed several times in a day, making it nearly impossible for these teens to concentrate and get anything done. These mood shifts can cause symptoms that are similar to attention deficit hyperactivity disorder (ADHD), and therefore this is just one more diagnostic dilemma for the therapist. Other research shows that teens with ADHD can also present in a very similar way as those with either conduct disorder or ODD. The possibility that both conduct disorder and ODD may be a component of ADHD or bipolar disorder is being researched. Therefore, both bipolar disorder and ADHD as well as conduct disorder or ODD are processes that the psychiatrist/therapist must take into consideration when attempting to diagnose a teen who is displaying severe behavior problems, such as those listed above. The psychiatrist/therapist may resolve the problem of overlapping behaviors and disorders by assigning more than one diagnosis to a child (dual diagnosis). And as many parents have discovered, because distinguishing among these disorders can be quite difficult, their child may receive one diagnosis from the therapist or psychologist and a different diagnosis from the psychiatrist. This only further adds to the concerns of the parents, leaving them to wonder if anybody at all knows what is really going on!

According to Merck's Manual, more than half of teens with conduct disorder stop exhibiting these behaviors in early adulthood, but about one third of the cases persist, developing into antisocial personality disorder or other mood or anxiety disorders. Children with conduct disorder tend to have a higher than expected incidence of medical and psychiatric illness at follow-up.

Treatment of Conduct Disorder and ODD

Treatment of all medical, neurological and psychiatric conditions by the appropriate caregivers can improve self-esteem and self-control. These kids will sometimes respond favorably to a very structured approach with clearly stated rules and immediate consequences for breaking rules. A home rules contract, which is set up with the help of the therapist and enforced uniformly by all caregivers, can clarify rules and consequences and provide structure for the teen. However, in some cases, only separation from the current environment, i.e. removing the child from the influence of his peers and/or a bad home environment, with external discipline and consistent behavior management and modification offer hope for success.

In the event that problems have become severe enough to require more intensive behavior modification in a residential setting, the World Wide Association of Programs six-level behavior modification programs can offer hope to parents who are dealing with teens diagnosed with either conduct disorder or oppositional defiant disorder.

I know a 6 year old that meets all the standards for ODD. In addition, she is cruel to animals (kicks her cats) and to people (pushed down a boy and repeatedly kicked him, pinched a child at school, slapped another child in the face, says mean things to other children, kicks and hits her mother). What would one make of this? The people in charge of this child think nothing is wrong. I have been begging them for years to get her some help.


Not much you can do when parents bury their heads in the sand.

I personally think it's a rare instance when ODD stands alone. Many of the kids on this board could have been diagnosed with it at one time or another -- mine included.

If she's unresponsive to traditional parenting and intentionally hurting animals and people, she could have a mental illnesses. Hope her parents intervene sooner rather than later.
