ABSTRACT

AIM: To validate a reduced and applicable to distinct location version of the only validated questionnaire of patient safety culture in managers in Spanish language. METHOD: Questionnaire validation study. Community of Madrid 2022. Reduction/adaptation of the original questionnaire Giménez-Aibar-Gutiérrez, 2013 Questionnaire was reduced from 85 items to 25; those local or not applicable were removed. Pre-test Semi-structured survey on comprehension and response scale. There was no need to modify the questionnaire. VALIDATION It was tested in 39 primary care managers without care activity. Internal consistency (α Cronbach), content validity (experts) and construct validity (factor analysis) were analysed. Usability analysis: Survey on time spent and non-response rate. RESULTS: α Cronbach=0.894. Content validity Experts deemed questionnaire was complete. Factor analysis: five factors explain 68% of variance. The factors corresponded to the dimensions of the theoretical construct. Factors, internal consistency of each and correlation with global score were commitment with patient safety α Cronbach=0.793, r=0.778; P<.001; procedures/reporting α Cronbach=0.83, r=0.806; P<.001; attitudes with patient safety α Cronbach=0.766, r=0.596; P<.001; clinicians involving α Cronbach=0.773, r=0.798; P<.001; patient safety communication α Cronbach=0.615, r=0.518; P=.001; usability survey 95% thought spent time was adequate. Non-response rate was 0%, except one item. CONCLUSION: In this work, a reduced and adapted version of questionnaire of Giménez-Aibar-Gutiérrez was validated at distinct location (Madrid region). Psychometric properties and usability, which were found, suggest that the reduced questionnaire is a reliable, valid and usable instrument to assess patient safety culture in managers of any place.
