Abstract
Since the 1960s, the application of psychological services and research to law enforcement settings (known as “police psychology”) evolved from being practically nonexistent to almost universal in a relatively short period of time (Scrivner 2006). Currently, psychologists provide a variety of services to law enforcement agencies, including performing evaluations for pre-employment selection, “fitness-for-duty” evaluations (FFDE), and counseling/treatment for psychologically troubled officers and first responders. The extensive use of personality assessment instruments in police psychology is not surprising given the fact psychologists have traditionally concerned themselves with issues of psychological measurement and test construction. In the contemporary practice of police psychology, assessment using personality measures is essential, being utilized in all of the abovementioned evaluations, in addition to other occasional applications (Weiss et al. 2008). This article provides a brief history of personality assessment in police and public safety psychology as it developed from 1916 to 2008.
