HCAT Measures

One of the major goals of HCAT lab is to develop sound measures for key constructs. Measurement is our passion. We believe that knowledge advances rapidly with (even small) gains in precision.


Below is (1) a list of our measures and (2) a list of measures we use all the time. Our goal is to expand this page to one day include all measures we find useful. Bookmark it now and you will have access to an ever growing catalogue of our measures and those we collect. All of our measures are free to use for any purpose. We don’t believe in charging $ for using measurement tools. In fact, we believe charging $ for using measurement tools is anti-science.
