8. Not all evaluative researchers have the luxury of measuring the client on the target behavior or problem before treatment begins. This weakness can be dealt with by measuring the client several times during the first treatment period, followed by a change in the treatment while continuing to measure the client’s target behavior or problem repeatedly during the second treatment period.
