Drawing on procedural justice theory and research, this study uses survey data from a sample of Jamaican high school students (N = 289) to evaluate hypotheses derived from the process-based model of policing. Findings reveal that the correlation between procedural justice judgments and police legitimacy is positive and statistically significant. Students who rate police practices more favorably in terms of procedural justice also report a greater willingness to help the police fight crime (e.g., report suspicious activity to the police) in their community. In combination, the findings show that these two key process-based model hypotheses generalize to the Jamaican context. Although the correlation between police legitimacy and behavioral cooperation is in the expected direction, the relationship is not statistically significant. The findings also show that students from impoverished local communities dominated by "area dons" are less willing to help the police fight crime. P olice agencies rely on citizens to help control crime in local communities.Among the ways residents can assist police in this regard include reporting known instances of crime and victimization, helping the police find suspected criminals, and reporting suspicious activity near their homes. Tyler's (2003) social-psychological framework, termed the process-based model, identifies salient factors that influence whether people aid the police in crime-fighting efforts. The focal point of Tyler's model is the manner in which legal officials exercise their authority during encounters with the public. The process-based model posits that individuals who perceive that the police behave in a manner consistent with the precepts of procedural justice (e.g., treat people respectfully and make fair decisions) will view the at Library -Periodicals Dept on March 22, 2015 pqx.sagepub.com Downloaded from
