Title
  • Creating Valid and Effective Measures: Using –optifact- to Create Better Summated Rating Scales
Author
  • Paul Millar
Physical Description
  • preprint
Notes
  • While scales are an integral part of the measurements involved in many research projects, few researchers make the effort to ensure that these scales are valid, reliable, uni-dimensional and consistent with relevant correlates. This presentation outlines how the Stata routine –optifact- can be used to create summated rating scales that are better measures of the concept at issue, yet often require fewer questions. An example using a major Canadian survey is presented to illustrate the potential for better analysis and potentially substantial cost savings in survey research.
