This article describes the development and psychometric evaluation of self-report measurement instruments in (nursing) research. The aim of this study is to gain more insight into, and understanding of the use of such instruments. To be more specific, this paper deals with: (1) What is a self-report measurement instrument?; (2) How to develop such an instrument?; (3) What is its psychometric quality in terms of validity and reliability?; (4) How to analyze an instrument statistically?; (5) Which are the pros en cons of a self-report measurement instrument in general?; and (6) Where do we find examples of good measurement instruments? These six questions will be answered with the help of several practical research examples. The article concludes with a few suggestions for literature concerning existing measurement instruments and their psychometric qualities.
