title: Interrater reliability decline under covert assessment.
abstract: This article highlighted representative studies on a methodological problem that may generalize to other observational methods and circumstances. A number of strategies have been suggested to combat this problem. Despite the need for additional research on this methodological problem and the remedial tactics discussed here, studies that deal with interrater reliability decline will surely be evaluated as more credible than those that overlook the problem.
