This study was conducted to develop a measurement model for the environmental ethics questionnaire. The research methodology was correlational and was conducted in measurement model. The statistical population of the study included all the 14391 secondary high school students in Hamadan city. The sample size, which was selected by stratified relative sampling method, was 986 students. The tool for data collection was the researcher-made Environmental Ethics Questionnaire (2019), which consisted of 5 components (i.e., water, soil, air, plants and animals). The initial questionnaire was developed on the basis of theoretical foundations and research background and contained 130 items. The content validity of the questionnaire was assessed by CVR method and the items with the relative validity coefficient of less than 0.29 (i.e., 26 items) were deleted. In addition, in a pilot study, the reliability of the questionnaire was calculated through Cronbach's alpha. After implementation of the questionnaire, the results showed that the structural model of environmental ethics has goodness of fit (GOF= 0.614). The results, also, indicated that all the questionnaire questions had a significant effect on their component. The results of the model, also, showed that the water component had the greatest effect on environmental ethics and the air component had the least effect on it. In addition, the results showed that there is a high internal correlation between the components of environmental ethics. In conclusion, it can be said that the researcher-made Environmental Ethics Questionnaire (2019) has the necessary psychometric characteristics for measuring environmental ethics.
