The authors examined the association between the Interpersonal Conflict Measures of the Inwald Personality Inventory (IPI) and law enforcement officer performance during domestic disturbances. Seventy-six officers completed the IPI and had their performance rated by supervisors and peers. There were modest correlations between peer ratings and the GD, US, and SP scales. Similar analyses examining supervisor ratings were nonsignificant. Marital status and years of law enforcement experience were related to supervisor ratings. Findings suggest interpersonal difficulties may contribute to poor performance, while law enforcement experience as well as experience in managing conflicts in the context of an intimate relationship may enhance performance during domestic disturbances.
