Exploring the Factor Structure of Environmental Attitudes Measure in a Sample of Indonesian College Students

The purpose of this study was to validate and evaluate the factor structure of the instrument for measuring attitudes towards the environment using factor analysis and multidimensional polytomous Rasch model. Participants in this study were 595 Indonesian university students (293 male and 302 female) with an age range of 18-24 (mean age = 21.01, SD = 1.65). The 22-items of Environmental Attitudes Measure were administered using online survey systems. This study generates a three-dimensional factor structure of environmental attitudes in the Indonesian college samples and supports the original scale's theoretical basis. The results of the multidimensional analysis of the polytomous Rasch model show that the psychometric characteristics of this instrument are excellent and have high separation reliability, both for items and person. The findings of this study can be used in future research to examine the interrelationship of environmental attitudes with other variables in the Indonesian sample. Limitations of this study are also discussed.
