Adaptation and Validation of An Environmental Attitudes Scale Among University Students

Objective: The aim of this study was to adapt and validate the AMANA Scale to assess environmental attitudes among higher education students. Methodology: An instrumental and cross-sectional research design was conducted with a sample of 130 university students. Data collection included demographic variables (age, gender, and location) and specific sustainability indicators, such as waste sorting and renewable energy usage. The psychometric properties were evaluated through internal consistency and confirmatory factor analysis (CFA). Results: The validation process resulted in a parsimonious scale consisting of 7 items distributed across two factors. The instrument demonstrated high internal consistency with a Cronbach’s Alpha of 0.81. Regarding structural validity, the sample adequacy was confirmed by an overall KMO of 0.79 and a significant Bartlett’s Test (χ 2 =364.21,p<.01). The two-factor model showed an exceptional fit, yielding an RMSEA of 0.00, a TLI of 1.041, and a BIC of -36.22, indicating a perfect and parsimonious fit between the theoretical model and the empirical data. Conclusion: The 7-item, two-factor AMAN-A scale is a highly robust, reliable, and efficient tool for measuring environmental attitudes. These findings provide a solid foundation for diagnosing environmental awareness and designing effective sustainability programs within university populations.
