Psychometric testing of the Swedish version of the measure of moral distress for healthcare professionals (MMD-HP)

Background: Moral distress has been described as moral constraints and uncertainty connected with guilty feelings of being unable to give care in accordance with one's values for good care. Various instruments to measure moral distress have been developed. The instrument measure of moral distress for healthcare professionals (MMD-HP) was developed to capture the experience and frequency of moral distress among various healthcare professionals. The MMD-HP has been translated and culturally adapted into the Swedish language and context; however, the translation has not been validated. Therefore, this study aimed to evaluate the validity and reliability of the Swedish version of the measure of moral distress for healthcare professionals (MMD-HP). Methods: Eighty-nine staff from various professions at a hospital in northern Sweden participated in the study. A confirmatory factor analysis was performed to check for consistency with the original version of the MMD-HP. To evaluate internal consistency, Cronbach's alpha was calculated for each domain and for the scale as a whole. Results: The scale as a whole showed a Cronbach's alpha of 0.96, with a range between 0.84 and 0.90 between the different subscales. A confirmatory factor analysis based on the original four-factor structure showed good fit indices with a χ2/df of 0.67, CFI at 1.00, TLI at 1.02 and NFI at 0.97. RMSEA was at 0.00, and SRMR was at 0.08. A comparison of the total score between three equally large groups of years of experience at the present workplace showed no significant differences (F = 0.09, df = 2, p = 0.912). Conclusions: We found that the Swedish version of the MMD-HP has shown validity and reliability for use in a Swedish context for measuring moral distress among health personnel
