Refining the medical student safety attitudes and professionalism survey (MSSAPS): adaptation and assessment of patient safety perception of French medical residents

Abstract : BACKGROUND: Implementing a patient safety curriculum for medical students requires to identify their needs and current awareness of the topic. Several tools have been developed to measure patient safety culture, but none of them have been developed in the French context. Our objective was to adapt and refine the psychometric properties of the MSSAPS, developed by Liao et al, to use it among general practice (GP) residents. METHODS: 1-We conducted a translation and transcultural adaptation of the MSSAPS questionnaire (28 items, 5 dimensions: safety culture, teamwork culture, experiences with professionalism, error disclosure culture and comfort expressing professional concerns) in accordance with the international recommendations. 2-We studied the new questionnaire' psychometric properties on a sample of GP residency students in 2016. This validation comprised 2 steps: a confirmatory factor analysis (CFA) for each dimension of the MSAPPS to explore the adequacy of the structure of the questionnaire; an exploratory factor analysis to refine the instrument, using a principal component analysis and Cronbach's α-coefficients calculation. A final CFA examined the structure validity of the refined questionnaire. 3-We described the items and the safety cultural scores in our sample of residents. RESULTS: Among 391 eligible students, 213 responded (54%). The initial structure was not confirmed by CFAs, showing a poor fit for 3 of the 5 dimensions: safety culture, teamwork culture and professionalism. Exploratory PCA led to 3 dimensions: Safety culture (PVE: 18.5% and 7 of 8 initial items), Experiences with professionalism (PVE: 17.8% and 5 of 7 initial items) and Error disclosure culture (PVE: 13.6% and 3 of 4 original items). Cronbach's α-coefficients were 0.74, 0.78 and 0.76 respectively. The final CFA confirmed the existence of the 3 latent dimensions with a good fit to the and highly significant structural coefficients (P < 0.001). Mean scores were equal to 65.4 [63.6; 67.6] for the safety culture, 66.9 [63.8; 70.1] for the experience with professionalism, and 54.4 [51.6; 57.2] for the error disclosure culture. CONCLUSION: This study reports satisfactory psychometrics properties of the French version of the MSAPPS and provides evidence of important training needs for GP residents in the field of patient safety culture.
