Several techniques for conducting studies of measurement integrity are explained and illustrated using a heuristic data set from a study of teachers' participation in decision making (D. L. Taylor, 1991). The sample consisted of 637 teachers. It is emphasized that validity and reliability are characteristics of data, and do not inure to tests as such (B. Thompson, 1991, 1992). An instrument found to produce valid, reliable data in one study may not do so in another because of phenomena external to the instrument. Because of this dilemma, an investigation of measurement integrity should be included as an important part of every study. Failure to do so may result in inaccurate findings that wrongly influence a field. Two tables present the illustrative data. (SLD)
