The Classmates Social Isolation Questionnaire for Adolescents (CSIQ-A): Validation and Invariance across Immigrant Background, Gender and Socioeconomic Level

Elisa Cavicchiolo, Laura Girelli, Fabio Lucidi, Sara Manganelli, Fabio Alivernini


It is widely acknowledged that the social relationships of adolescents with their classmates can have a significant impact on their adjustment to the school environment and their psychological well-being. This study, based on a random sample of 36,712 students, investigates the psychometric properties and the validity of the Classmates Social Isolation Questionnaire for Adolescents (CSIQ-A), a time-efficient instrument intended to measure peer relatedness at school. Confirmatory factor analysis established the bidimensional structure of the scale. The CSIQ-A showed measurement invariance across gender and across students with different immigrant backgrounds and socioeconomic status. A positive correlation between peer acceptance, peer friendship and positive affect provided support for the criterion validity of the measure. The CSIQ-A proved to be a psychometrically sound measure, which can be reliably used with  adolescents with different sociodemographic and cultural characteristics. In conclusion, the CSIQ-A makes it possible to directly measure the effects of classroom interventions that are aimed at promoting peer relatedness and preventing social isolation.
