Abstract Purpose The purpose of this study was to investigate flourishing among medical (MD), physician assistant (PA), and nurse practitioner (NP) students, using the novel Secure Flourish Index (SFI). Method MD, PA, and NP students from two institutions completed the traditional SFI (tSFI), then applied a percentage weight to each of the six domains (maximum total 100%) based on perceived relative importance to their overall flourishing, creating a novel self-weighted SFI score (swSFI). The Bland–Altman (BA) plot was used to assess the magnitude of agreement between scores. Results The BA plot (n = 281) revealed a mean bias of .07(95% CI -.50,.63). Eighteen participants (6.4%) fell outside of the calculated BA limits of agreement [-9.31 [95% CI - 10.27,-8.45] and 9.45 [95% CI 8.49,10.41]]. Linear regression revealed the mean BA score is predictive of the mean difference between scores [R2 = 0.07, F(1,280) = 21.1, p < .001] indicating bias in agreement between the scoring systems as mean flourishing score changes. Conclusion Accounting for individual values is important when measuring student flourishing but is missing from current operant definitions. The overall mean difference (bias) in tSFI and swSFI scores is minimal (.07, possible range 0–120). However, the bias becomes larger as individual mean flourishing scores move towards both the high and low ends of the flourishing spectrum. This indicates that the influence of weighting flourishing domains is larger for individuals with high or low flourishing than those with moderate flourishing.
