Suppose you need to evaluate your practice where you are treating a group of 12 victims of violent crimes. These clients were victimized at some time in the past 3 months and they are experiencing anxiety as a result, and you will measure anxiety as one means of evaluating the success of your service. You are providing a group treatment intervention where you will meet with your 12 clients once per week for a period of 6 months. You have four questions to answer: (1) What are the two criteria for selecting a research design that you should answer? (2) How do you answer these two questions in this situation? (3) What research design do you think would be feasible in the typical practice situation where you faced this situation? (4) Does this design control for the threats that should be of
special concern?
What will be an ideal response?
Ans: The two questions should be (1) How long has the problem been in existence? and (2) How long is the treatment period? This problem happened in the past 3 months and the treatment will be for 6 months. Because the problem was a single-incident trauma, you would expect that victims will recover on their own over a period of time. The amount of time for this spontaneous recovery is not clear, but the fact that treatment occurs over a 6-month period of time might suggest that maturation is a special concern. The comparison group design controls for maturation but the one-group pretest–posttest design does not.
