The Williams family was self-referred by the mother, Mrs. Jane Williams. The reason given for the referral was the acting-out behavior of the 17-year-old son, Ian. Ian was reported to lose his temper easily and when he did, to be "uncontrollable." He had pulled a knife on his mother and 16-year-old sister, Dianne, ordered his sister around, demanded that she do things for him such as making him meals, and physically pushed her when she did not listen to him.
