Question 5

On a bad day, have you ever been irritable? Have you ever used a harsh tone or even been verbally

disrespectful to your parents or teachers? Everyone has a short temper from time to time, but current

statistics indicate that between 16% and 20% of a school population suffer from a psychological condition

known as Oppositional Defiance Disorder, or ODD.

ODD symptoms include difficulty complying with adult requests, excessive arguments with adults, temper

tantrums, difficulty accepting responsibility for actions, low frustration tolerance, and behaviors intended to

annoy or upset adults. Parents of children with ODD can often feel as though their whole relationship is

based on conflict after conflict.

Unfortunately, ODD can be caused by a number of factors. Some students affected by ODD suffer abuse,

neglect, and severe or unpredictable discipline at home. Others have parents with mood disorders or have

experienced family violence. Various types of therapy are helpful in treating ODD, and some drugs can treat

particular symptoms. However, no single cure exists.

The best advice from professionals is directed toward parents. Therapists encourage parents to avoid

situations that usually end in power struggles, to try not to feed into oppositional behavior by reacting

emotionally, to praise positive behaviors, and to discourage negative behaviors with timeouts instead of

harsh discipline.

Based on the passage, which of the following statements seems most true?

Options :

A : Harsh disciplinary measures must be used to control children with ODD.

B : Parents of children with ODD often engage in risk-taking activities.

C : A variety of parenting techniques can be used to help children with ODD.

D :

Children with ODD must be physically aggressive to be diagnosed.
