BackgroundMoral distress is a problem and negative experience among health-care professionals. Various instruments have been developed to measure the level and underlying reasons for experienced moral distress. The moral distress thermometer (MDT) is a single-tool instrument to capture the level of moral distress experienced in real-time.AimThe aim of this study was to translate the MDT and adapt it to the Swedish cultural context.Research designThe first part of this study concerns the translation of MDT to the Swedish context, and the second (...) part the psychometric testing of the Swedish version.Participants and research context89 healthcare professionals working at a hospital in northern Sweden participated. Convergent validity was tested between MDT and Measure of Moral Distress-Healthcare Professionals (MMD-HP), and construct validity was tested by comparing MDT scores among healthcare professionals. MDT was compared with responses to the final questions in MMD-HP. One-way ANOVA, Welch’s ANOVA, Games–Howell post-hoc test and Pearson’s correlation analysis were done.Ethical considerationsThe study was approved by the Swedish Ethics Review Authority (dnr 2020-04120) in accordance with Helsinki Declaration.ResultsThe translated Swedish version of MDT was described as relevant to capture the experience of moral distress. The mean value for MDT was 2.26, with a median of 2 and a mode value of 0. The result showed moderate correlations between the MDT and MMD-HP total scores. There was a significant difference when comparing MDT and healthcare professionals who had never considered leaving their present position with those who had left and those who had considered leaving but had not done so, with the latter assessing significantly higher moral distress.ConclusionThe MDT is an easily available instrument useful as an extension to MMD-HP to measure the real-time experience of moral distress among healthcare professionals in a Swedish context.
