The participants consisted of 640 individuals who participated in the study in 2023, from all regions of Turkey. First, literature review on emotional intimacy in relationships was conducted. Then, semi-structured interviews were made with six individuals who were in romantic relationships. In collaboration with eight experts and one academician, an item pool was created. After the items were shared with six experts in the field, they were assessed for content validity and finalized after they had been reviewed by them. The first step of the study was to perform an exploratory factor analysis of the data. The results of the exploratory factor analysis revealed a unidimensional structure consisting of 10 items with an eigenvalue of 5.377, explaining 53.774% of the total variance. Following the initial factor analysis phase, a confirmatory factor analysis was carried out and it was found that the fit indices met the required criteria. Following the analysis of the data, it was concluded that the Emotional Intimacy Scale is a valid and reliable tool for measuring emotional intimacy. © 2025 Elsevier B.V., All rights reserved.en10.35365/ctjpp.25.2.05info:eu-repo/semantics/openAccessEmotional IntimacyIntimacyRomantic RelationshipScale DevelopmentArticle721511572-s2.0-105009353214Q4
