The current study examined the nature and extent of endorsement of PMIEs, the nature and severity of MI symptoms related to endorsement of a PMIE, and the relations between extent of endorsement of PMIEs and MI symptoms. We hypothesized that (1) PMIEs perpetrated by others would be endorsed to a greater extent than PMIEs perpetrated by oneself; (2) medical professionals who endorsed a PMIE would report significantly greater severity on all MI symptoms compared to medical professionals who did not endorse a PMIE; (3) experiencing PMIEs (perpetrated by oneself and/or others) to a greater extent would predict higher levels of MI symptom severity, and MI symptom severity would specifically be most strongly predicted by PMIEs perpetrated by oneself. Hypotheses were examined using t-tests, Pearson's r correlations, and multiple multivariate regression analyses. First, the current study found that PMIEs perpetrated by others were endorsed to a greater extent than those perpetrated by themselves; second, greater exposure to PMIEs was associated with significantly greater severity of 10 of the 14 outcomes. Third, PMIEs perpetrated by oneself predicted more MI symptomatology than PMIEs perpetrated by others, indicating that while PMIEs perpetrated by others are more common, PMIEs perpetrated by oneself are more strongly associated with MI outcomes. This study highlights the widespread and harmful impact of PMIEs among medical professionals.
