Analysis of the validity and reliability of a questionnaire to measure students’ perception of inclusion of sustainability in engineering degrees

Abstract

There are multiple questionnaires in the literature that try to gather university students’ perception about sustainable development (SD), but they are mainly focused on determining the students’ knowledge and attitude about sustainability. As the existing questionnaires did not fit the type of analysis that is intended to carry out, a new questionnaire was developed, adapted to the aims and context (engineering students) of the pretended study. The questionnaire contains two scales; one to determine the level of insertion of sustainability and the other to measure the importance that students give in their training process to the three dimensions of sustainability: economic, environmental and social. This new instrument requires a validation process to ensure its content – validity, reliability and clarity. The aim of this paper is to describe the validation process.
