Five criteria are proposed for evaluating performance in research studies: the directness of sampling, the responsiveness of the target, the reliability of the observers, the frequent assessment of the target during the intervention period, and the critical nature of the target. A case study illustrates effectiveness of the criteria. (Author/CR)
