A psychologist has developed a treatment she believes will prevent child abuse. Unfortunately, the

psychologist was unable to find enough people who abuse their children to conduct a study to

demonstrate the effectiveness of the treatment. Ignoring the ethical considerations of such an

experiment, design a study that would accomplish the following:
a. produce a sufficient sample of child abusers for the study
b. demonstrate conclusively a cause and effect relationship between the treatment and a reduction in

child abuse
