The construct validity and refinement of process-based policing measures

Prior tests of Tyler's process-based model of policing have left basic measurement questions unanswered. With a sample of 432 adults from a nationwide telephone survey conducted in spring 2005, factor-analytic procedures were used to develop more valid scales and to test process-based model hypotheses. Regression analyses confirmed that procedural justice judgments affect police legitimacy, which in turn influence both cooperation with police and compliance with the law. When legitimacy was disaggregated, trust in the police predicted both of the outcomes of interest. Obligation to obey, however, was not significantly associated with either compliance or cooperation. Finally, distributive fairness appeared to be as salient as legitimacy in facilitating participant cooperation.
