Introduction: Ethical climate theory traditionally conceptualizes organizational ethics as a set of distinct normative dimensions. However, recent evidence suggests that ethical perceptions may converge into a unified climate in culturally cohesive and institutionally regulated contexts. This study aims to validate the Emirati Higher Education Institutions Ethical Climate (EHEC) scale and examine whether the ethical climate operates as a unidimensional construct within Emirati higher education institutions. Methods: A quantitative validation design was employed using survey data from 200 academic and administrative staff across three Emirati universities. Data were analyzed via exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), alongside reliability and validity assessments, using IBM SPSS (Version 27) and AMOS (Version 24). Principal axis factoring without rotation was applied to examine the latent structure, followed by CFA for model fit testing and to compare alternative structures. Results: EFA revealed a single dominant factor with an eigenvalue of 11.8, explaining 47.1% of the total variance, and factor loadings ranging from 0.46 to 0.79. CFA confirmed the adequacy of the one-factor model (χ2/df = 2.31; CFI = 0.93; TLI = 0.91; RMSEA = 0.06; SRMR = 0.05). The scale demonstrated excellent reliability (Cronbach’s α = 0.93; CR = 0.95) and acceptable convergent validity (AVE = 0.48). Comparative analysis showed that the unidimensional model substantially outperformed the traditional five-factor structure. Discussion: These findings indicate that the ethical climate in Emirati higher education institutions is perceived as a single, shared institutional environment rather than as separate ethical dimensions. The validated EHEC scale provides a parsimonious, reliable, and context-sensitive instrument for assessing the ethical climate, suggesting that ethical climate theory may require contextual adaptation in institutionally cohesive and collectivist settings.
