Although the concept that motivation has a substantial effect on the success or failure of individuals is accepted, few motivation studies have used police personnel as subjects. However, the existing research indicates that police officers have a high power drive and a relatively low need for social acceptance. In the present study, police occupations listed in the 'Dictionary of Occupational Titles' were analyzed in terms of their connections with the need for achievement, the need for affiliation (social acceptance), or power. Successful performance of nearly every position on the police force was found to require individuals with a high need for power. Many categories also required varying levels of the two other needs. The duties of patrol and traffic officers suggested that individuals would be most fulfilled if they had a very high need for power, a moderate need for achievement, and a very low need for affiliation. The most balanced need profiles belonged to activities performed by sergeants, ID commanders, desk officers, community relations officers, department secretaries, and corrections officers. Training programs might help increase individuals' specific need levels to better fit their jobs. Motivation testing would also improve internal promotion. Recommendations for additional research, data tables, and 21 references are supplied.
