Abstract
BACKGROUND: Despite the importance of understanding ethical climates in Indonesian organizations, a standardized scale for measuring this is lacking. Therefore, this study aims to adapt, validate, and ensure the consistency of the Ethical Climate Questionnaire (ECQ) within Indonesia's cultural context. METHODS: Data were collected from 565 Indonesian individuals aged 18 or older, using an online survey and convenience sampling. To ensure accurate measurements, Beaton's guidelines were followed. Reliability was assessed using Cronbach's alpha and McDonald's omega, while validity was examined through various analyses including content validity index and confirmatory factor analysis. RESULTS: The Indonesian version of the ECQ measures egoist, benevolent, and principled ethical climates reliably (Cronbach's alpha: egoism=0.809, principle=0.920, benevolence=0.910). Validity analyses confirm the questionnaire's validity. Demographic analysis shows age impacts the principle dimension, while organizational type affects all dimensions. CONCLUSION: The Indonesian version of the ECQ demonstrates strong psychometric properties and cross-cultural adaptability, making it a valuable tool for assessing ethical climates among Indonesian individuals aged 18 or older.
