Researchers in a wide range of disciplines are frequently involved in the development and revision of multiple-item measuring instruments, including scales, tests, inventories, questionnaires, surveys, subscales, and testlets. Scores obtained from these measuring instruments are usually employed in subsequent analyses that address substantive research questions. To a substantial degree, the quality of these instruments determines the extent to which the analyses and modeling efforts produce trustworthy results. To construct scales of high psychometric quality, researchers must engage in many activities aimed at building initial versions of the instruments and then repeatedly revising them to improve their performance.
