     This article focuses on the importance of expert validation in the construction and evaluation of questionnaires, particularly in the context of satisfaction surveys. The article highlights that the involvement of experts provides an overview and helps understand the limitations of the coefficients used, such as Aiken's V and Cronbach's Alpha, as well as their proper interpretation.

     The text mentions that expert validation can also provide additional information about the interpretation of results and key concepts in the evaluation of measurement instruments. Furthermore, it points out that expert validation can be useful in assessing the agreement among experts' ratings in an impact study.

     Next, the importance of Aiken's V and Cronbach's Alpha in evaluating the validity of data obtained through questionnaires is emphasized. Aiken's V assesses the convergent and discriminant validity of a questionnaire, while Cronbach's Alpha evaluates the internal consistency of scale items.

     It is highlighted that obtaining positive results in both coefficients enhances the validity of data by demonstrating good convergence, discrimination, and consistency in measuring the target construct.

In conclusion, the article emphasizes that expert validation and the use of coefficients such as Aiken's V and Cronbach's Alpha are fundamental in improving the validity of data in satisfaction surveys and other measurement instruments.     These tools provide valuable information to ensure the accuracy and reliability of the results.
