Development and validation of a questionnaire for measuring the sustainability factors of quality management systems

This study elaborates on the development of a questionnaire as a survey instrument for measuring the sustainability factors of quality management systems. The scope covers the discussion on the content and face validity performed by the experts. The analysis contributes to the existing body of knowledge by utilising the content validity index (CVI), kappa-coefficient and Aiken-V. Validity analysis comprises two stages; the first involves a content validity approach by nine experts using a four-rating scale measurement (relevance level). The second stage requires face validity by lay experts using a five-rating scale measurement (importance level). The preliminary questionnaire consists of three constructs with two categorical questions. The outcome from the content analysis shows that two items were removed from the values and technique constructs, respectively. This paper significantly contributes to guiding other researchers in conducting content and face validity of the preliminary item questionnaire developed within the context of quality management.
