So I took little pieces here and there from articles, books, and webpages and compiled them into own comprehensive approach to validating questionnaires.
I have used this approach to publish questionnaire-based articles.
A typology is similar to an index except the variable is measured at the nominal level.
Indexes are constructed by accumulating scores assigned to individual attributes, while scales are constructed through the assignment of scores to patterns of attributes.
The index of consumer confidence, for example, is a combination of several measures of consumer attitudes.
Alternative forms reliability checks how similar the results are if the research is repeated using different forms of the scale.
Internal consistency reliability checks how well the individual measures included in the scale are converted into a composite measure. Internal validation checks the relation between the individual measures included in the scale, and the composite scale itself.
Also, I was awarded a grant to validate a questionnaire evaluating clinicians’ impressions of electronic decision making tools.
I guess journal editors and reviewers think that I know what I am doing, or maybe they are deferring to my “expertise” because, like my university professors, they are not sure about what to do.
