IRB. RESULTS: PD (alpha = 0.7) mean scores were significantly (p < 0.001) correlated with emotion regulation (r = -0.3) and stability (r = -0.3), which were significantly correlated (r = 0.5) to each other. Cluster analysis converged on four significant clusters after nine iterations. Two clusters (45%) aligned with correlation statistics with PD inversely related to emotion regulation and stability. Two clusters (55%) yielded a direct relation between PD, emotion regulation, and stability.

... LUSIONS: Machine learning via cluster analysis resolved conflicting reports of the moderate relationship of medical student PD, emotion regulation, and disposition. Some students reported PD levels in accordance to correlation analysis indicating empathy increased with emotion regulation and stable personality. Surprisingly, other students decreased PD under the same conditions, which was not revealed in correlation analysis, but the moderating factor has not yet emerged.
