Psychometric properties of the Mexican version of the opening minds stigma scale for health care providers (OMS-HC).

Background: Healthcare providers are one of the main groups that contribute to the stigmatization of people with mental disorders. Apathy, accusation, fatalism, and morbid curiosity are the most common forms of stigmatization encountered, and these are associated with inadequate treatment, reduced treatment adherence, decreased help-seeking behavior, an increased risk of relapse, and complications with other medical conditions. The aim of this study was to examine the psychometric properties of an adapted Spanish version of the Opening Minds Stigma Scale (OMSHC) for healthcare providers in Mexico and identify certain stigmatizing attitudes within this group. Methods: An ex-post facto cross-sectional observational study was conducted with 556 healthcare providers in Mexico, with an average age of 29.7 years, who were mostly women (80.4%). Validity was examined through confirmatory factor analysis. Differences according to gender, discipline, occupation, and educational level were analyzed using multivariate methods. Results: The factor structure of the OMS-HC, consisting of three subscales identified by the original authors of the instrument (attitudes of healthcare providers towards people with mental illness, secrecy/help-seeking, and social distance), was confirmed. The model demonstrated good fit (x²/df = 2.36, RMSEA = 0.050, CFI = 0.970, TLI = 0.962, SRMR = 0.054, NFI = 0.950, PNFI = 0.742). Internal consistency was found to be adequate (α = 0.73, ω = 0.76) for the scale itself and slightly lower than acceptable for the subscales. Significant differences were found by discipline, educational level, and, for student providers, by academic semester. Higher scores were observed on the OMS-HC scale among nursing and medical professionals, undergraduate students, and those in early semesters. Conclusions: The Spanish version of the OMS-HC has demonstrated adequate psychometric properties and could be a useful tool to facilitate research on this topic in Mexico, and to carry out comparative studies with healthcare personnel in other Spanish-speaking countries.
