RESUMO
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.
