Background Different studies have shown the importance of corporate reputation, corporate image and corporate identity and how they are present in the healthcare field. These studies show that these terms establish reputation as a socially constructed asset, which has been gaining relevance in organizations due to its increasing importance as a strategic resource. The aim of this study is to analyze the psychometric properties of an instrument used to measure reputation in the banking field, in its Spanish version, adapted to the health sector, thus determining whether it is a reliable and valid instrument to be used in future research on samples of users in the health sector. Material and Methods In a pilot phase, the survey was applied to 97 patients. Then, the restructured instrument was applied to a sample of 323 men and women who attended the Dental Clinic of the Andrés Bello University, Concepción (Chile). During the pilot phase and application of the instrument, two exploratory factor analyses, Bartlett’s test, the Kaiser-Meyer-Olkin coefficient (KMO), the Principal Component Analysis (PCA) and the Varimax method with Kaiser normalization were applied. During the applicability analysis phase of the instrument, two confirmatory factor analyses were also applied for Relational Commitment (RC), Behavioral Intention (BI) and Relational Value (RV). Results According to the results obtained, the instrument initially created by Khan, Kadir and Wahab for the banking area can be considered reliable and solid for estimating reputation in the health area. The adaptation made to the instrument is considered to exhibit appropriate psychometric properties consistent with the original instrument. Conclusions Measuring relational value can go a long way in determining the future behavior of users who are accustomed to visiting an organization associated with the health sector.
