The current study aimed to test the factorial structure and psychometric properties of a parent version of the Multidimensional School Climate Questionnaire (MSCQ), a multi-informant and multidimensional measure of school climate recently developed and validated in Italian for a student version, by also providing evidence of measurement invariance between students and parents. Participants were 320 parents, mostly mothers, and 339 students enrolled in four middle schools in Northern Italy. The confirmatory factor analysis (CFA) showed a good fit for the expected six-dimension model (Student Support, Home-school Relations, Student Relations, Student-Teacher Relations, Educational Climate, Justice). All factors were positively correlated with each other and reported good Cronbach's alphas and composite reliability scores ([omega]). Full configural and metric and partial scalar invariance were achieved between parents and students. These findings confirm that the parent version of the MSCQ is a psychometrically sound measure to assess multidimensional perceptions of school climate. Lastly, limitations and practical implications are discussed.
