This research provides original data on the study of obsessive-compulsive personality traits in law enforcement. The study explored prevalence of obsessive-compulsive personality traits (OCPT) in law enforcement (compared to the general population) in association with the occupational need for such characteristics in that profession (orderliness, organized, attentive to detail, display restricted affect, adhere to laws and regulations, and assume leadership roles). While many studies seek to explain police personality, no literature could be found regarding prevalence of OCPT in sworn peace officers. Degree of OCPT was measured by the total mean score on the Five Factor Obsessive-Compulsive Inventory (FFOCI) and compared using a one-tailed independent samples t-test. Differences between two groups across 12 subscales were analyzed retroactively using a MANOVA for qualitative descriptions of each group. Research revealed, with statistically significant results (p<.01), that prevalence of OCPT is significantly higher overall in law enforcement peace officers when compared to non-law enforcement participants. Results from this study contribute meaningfully to police psychology within the field of forensic psychology. Results have the potential to influence supplemental assessment for peace officer candidacy screening.
