Abstract
A methodology for evaluating Likert-type scales is presented. Multitrait scaling is a straightforward approach to scale analysis that focuses on items as the unit of analysis and utilizes the logic of convergent and discriminant validity. Multitrait scaling is illustrated with the Multitrait Analysis Program, using patient satisfaction data from the Medical Outcomes Study.

The present interpretation of construct validity is not "official" and deals with some areas where the Committee would probably not be unanimous, but the present writers are solely responsible for this attempt to explain the concept and elaborate its implications.

Form II of the Patient Satisfaction Questionnaire (PSQ), a self-administered survey instrument designed for use in general population studies, well represents the content of characteristics of providers and services described most often in the literature and in response to open-ended questions.

Loneliness was uncorrelated with the six different health-related behaviors assessed in this study and the results of this study indicate that the ULS-8 is reliable, valid, and a better substitute for the Uls-20 than is the U LS-4.

Using the notion of a generalized proximity function comparison discussed by Hubert (1978), alternative indices are proposed for evaluating correlational pattern within a multitrait-multimethod matrix and complement the original Campbell-Fiske emphasis on ordinal comparison when assessing convergent and discriminant validity.
