Abstract
Introduction: Collective Moral Disengagement (CMD) employs mechanisms that distort moral perception and justify questionable behaviors within a group, allowing members to ethically disengage from harmful actions. The aim of this study was to evaluate the psychometric properties of the Classroom Collective Moral Disengagement Scale (CCMDS) in Peruvian adolescents. Method: A sample of 646 Peruvian adolescents from seven secondary educational institutions (average age 13.73 years) was analyzed. The scale was translated into Spanish and assessed using Confirmatory Factor Analysis and Item Response Theory. Results: The instrument was found to follow a unidimensional model with 17 items, showing adequate fit indices and reliability (a = .97; w = .97). Invariance by sex and age was confirmed, demonstrating equivalence across both groups. The IRT results supported the scale’s reliability and validity. Conclusions: The scale has been shown to have high levels of psychometric quality, making it suitable for evaluating strategies that may pose a risk to the school environment for this population.
