Assessing the evidence-base of conventional and non-conventional veterinary therapies
The quality of any investigation depends, in part, on the quality of the data collection instruments used. Therefore, in this communication, we intend to present the various stages of the process of preparing a questionnaire. We will guide our approach by following parameters considered essential, namely: research objectives and hypotheses, questionnaire sections, questionnaire questions, response scales and methods of data analysis. In addition to construction, we will also address two important characteristics quality instruments: validity and reliability.
Experience has shown that the benefits resulting from well-designed questionnaires can be substantial in terms of the quality of the information collected.
