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.
This two-day seminar provides a comprehensive introduction to the field of scale construction and development in the social and behavioral sciences, especially as applied to empirical settings where measuring instruments consist of multiple components or items with no guessing. Throughout the seminar, many empirical examples are utilized from the clinical, educational and social disciplines. The popular latent variable modeling software Mplus is used for all the examples, along with a detailed discussion of the command syntax and interpretation of the output.
Participants in this seminar can expect to come away with:
1. A nuanced understanding of the conceptual foundations and basic mathematical and statistical relationships underlying behavioral instrument construction and development.
2. The ability to understand, interpret and explain the output from statistical software for achieving the goals of psychometric scale construction and revision.
3. An appreciation of the advantages of a thorough study of the underlying latent structure of a tentative version of a multi-component instrument.
4. Practical tools and strategies for constructing an initial version of a scale.
5. Methods for revising a scale in order to achieve higher psychometric standards.
6. The ability to deal with issues arising in the practice of scale construction and development.
