Prior research assessing police misconduct has generally focused on prevalence and demographic correlates while neglecting traditional criminological theories. Some recent research has begun to fill the void in this area, but the link between self-control and police misconduct has yet to be explored. The current study utilizes a behavioral measure of self-control to evaluate the extent to which low self-control predicts police misconduct. Data from a sample of 1,935 police officers from the Philadelphia Police Department are analyzed, and the results generally indicate that low self-control is related to police misconduct. Specific findings, policy implications, and directions for future research are discussed.
