Validación de un cuestionario sobre formación docente para atender a la diversidad

Although there are numerous studies linked to the analysis of the training needed by teachers to respond to student diversity, there are few valid and reliable instruments that allow us to assess the preparation required to do so from a broad and up-to-date perspective. Under these coordinates, the current study aims to analyse the psychometric characteristics of a questionnaire designed ad hoc and aimed at assessing the training needed to cater for an increasingly diverse student population. After designing and applying the instrument to a sample of 376 teachers, its reliability and validity are studied. For the reliability study, the internal consistency of the questionnaire was calculated using Cronbach's alpha coefficient. For the validity analysis, we chose to calculate the content validity, using the technique of expert judgement in the field, and the construct validity, using factor analysis. The results obtained show that an instrument has been developed for the systematic and orderly collection of information from the target population, which is at the same time congruent, internally consistent, valid and highly reliable. In this sense, the instrument represents a valuable and up-to-date contribution to the scientific field in which it is framed.
