The head of the Teen Intervention Center believes that troubled youth are not getting the message if they complete the center’s 5-week education program but still have subsequent encounters with law enforcement. When they first come to the center, teens are broken up into groups of 15 to meet with a counselor and answer questions about what society defines as acceptable versus unacceptable behaviors.

(a) If you were the head of counseling at the center, what knowledge might you gain by asking each group of teens similar questions at the end of the 5-week program?

(b) Is there any reason to expect different responses to the initial questions and those asked at the end of the program? Explain.

(c) What type of research design would you be using if you administered a questionnaire to the same group of individuals at the outset of treatment, at the end of treatment, and 6 months after treatment?
