VALIDATION OF A QUESTIONNAIRE ON INCLUSIVE EDUCATION: TEACHER AND STUDENT VERSION

ABSTRACT

Current legislative framework in the field of inclusive education requires collection methodologies aligned with the latest paradigms. Thus, this study aims to present the metric qualities (reliabillity and validity) of the Questionnaire on Inclusive Education, in its dual version: teachers and students. Based on the literature review and the consultation of validated instruments, an initial version, assessed by ten experts, was established for content validity (CV) analysis. All items were considered representative, presenting indices (IVC) higher than .90 and moderate agreement (k>.30). In the pre-test, with ten participants (n teachers=5, n students=5), reliability was confirmed at the level of total internal consistency (α teachers =.83; α students =.95) and temporal stability (r teachers=.92; r students=.80). The construct validity was analyzed by applying the final version to 305 teachers, aged 27 to 68 years (M=51.41; SD=7.73) and 82 students, aged 6 to 20 years (M=12.96; SD=3.32). The correlations between sections are moderate but contribute significantly (.74>r<.85) to the total. The exploratory factor analysis indicates a three-factor and a one-factor solution explaining 41.88% and 48% of the total variance, for teachers and students, respectively. The questionnaire is a reliable tool to study perceptions, practices and inclusive cultures experienced at school.
