Translation, adaptation and validation in Catalan of a questionnaire about patient safety culture: The MOSPSC (Medical Office Survey on Patient Safety Culture) questionnaire

Introduction: Patient safety is an essential dimension of quality of care and a priority in health policies. The diffusion of the security culture is a key strategy and the questionnaire MOSPSC (Medical Office Survey on Patient Safety Culture), in its English and Spanish versions, has proved to be a good instrument to 'measure it'. The aim of this work is to translate, adapt and validate the questionnaire in Catalan. Material and methods: Translation, retrotranslation and adaptation of MOSPSC questionnaire of the AHRQ (Agency for Healthcare Research and Quality). Reliability and validity analysis of the adapted questionnaire. Results: It is a simple, well accepted and valued questionnaire, although extensive. Catalan version facilitates more precise comprehension and improves completion. We found small response percentages 'do not apply or do not know' in questions from Section F (At the Center) but notable in some questions referred to specific professional staff. For most items show suitable discrimination rates and both the complete questionnaire and subscales extracted after factor analysis obtain good reliability indexes. Conclusions: Final version, very similar to original and Spanish adapted, will allow comparisons as well as monitoring/follow-up after implementation of improvement strategies. Due to its length, it could be assessed using only related dimensions. (c) 2019 FECA. Published by Elsevier Espana, S.L.U. All rights reserved.
