Re-assessing the validity of the Moral Sensitivity Questionnaire 33 2 alumni were sent the access key to the web-based set of questionnaires. In all, 294 subjects were willing to participate: 176 PAs and 118 NPs, meaning a response rate of 52.7% (ie, 155/294). Upon closure of the online survey (between January and March 2015), 155 respondents had completed all of the questionnaires. In all, 139 alumni, who initially consented to participate, eventually did not reply to the survey. Therefore, no information about this group was available that could be used to test for selection bias. All questions in the Qualtrics online survey environment were forced choice, so there were no missing data. The “Strengthening the Reporting of Observational Studies in Epidemiology” (STROBE) checklist was employed. Ethical approval and consent to participate According to the statement by the Central Committee on Research Involving Human Subjects (www.ccmo.nl) , no Institutional Review Board (IRB) approval was warranted for this type of survey study among volunteer professionals. This study was performed in accordance with the tenets of the Declaration of Helsinki (General Assembly of the World Medical Association, 2014). Only the first author (LK) had access to the online survey data. Academic integrity statement The dataset in the current study was the same as the one in Kuilman et al (2019) (Kuilman, Jansen, Middel, Mulder, & Roodbol, 2019). However, from that pool different, variables were used, focusing on different research questions. Only the MDS and the indicator for moral reasoning (DIT-N2) were used in both studies, albeit with different hypotheses and functionality (independent vs dependent variable) Statistical analyses All data were analysed using SPSS Statistics for Windows, Version 25.0. CFA was performed using SPSS AMOS, Version 23.0. Bivariate analysis For categorical data, we used the chi-square test (Fisher’s exact tests for 2 × 2 contingency tables) and the difference-between-proportions test (Newcombe & Altman, 2000). For continuous variables, we used the Student’s t-test for independent samples.
