Recent theoretical advances in the social psychology of procedural justice have facilitated the development of a process-based approach to policing. This approach emphasizes the fairness of the manner in which the police exercise their discretion during encounters with citizens. However, little is known about the effects of procedural justice on citizen behavior during encounters. Applying the theories of procedural justice and the social interactionist theory of coercion, this dissertation uses data from systematic social observations of police-citizen encounters to examine how procedurally fair behavior of the police affects two types of citizen behavior, citizen disrespect and noncompliance with police requests. A series of logistic regression models show that, as suggested by process-based policing, procedurally fair behavior of the police has substantive influence on citizen behavior. However, some procedural justice factors differentially affect citizen disrespect and noncompliance, suggesting that these two types of citizen behavior are distinct forms of behavior and should be examined separately. Further analyses reveal that some procedural justice factors interact with other independent variables and influence citizen disrespect and noncompliance. These findings demonstrate the importance of understanding the effects of various factors, especially police procedurally fair behavior, on citizen cooperative interactions. The implications of these findings, for both policy and future research, are considered.
