abstract: Prior ethnographic research has found some relatively consistent factors that influence an officer’s use of force (e.g., organizational and suspect and officer characteristics). However, very little research has explored the effect department size in and of itself may have on force displayed during a police/citizen encounter. This study used data from the 2010 – 2013 Arizona Arrestee Reporting Information Network (AARIN) to examine the relationship between departmental size and officer use of force. Participants in this data collection cycle were limited to adult male and female arrestees (N = 2,273). AARIN personnel conducted confidential interviews and used a Police-Contact Addendum to document the type of forced employed by police during their current arrest. This study sought to answer the following research question: does the likelihood of an officer employing use of force increase (or decrease) in relation to department size the officer is nested in? The results indicate that citizens who are arrested by officers from a larger agency are more likely to report experiencing use of force during their arrest when compared to those arrested by officers from small and medium sized agencies. / Dissertation/Thesis / Masters Thesis Criminology and Criminal Justice 2017
