The Convergent and Discriminant Validity of Procedural Justice and Police Legitimacy: An Empirical Test of Core Theoretical Propositions

Purpose

Procedural justice and police legitimacy have been recognized as important antecedents to people's willingness to cooperate with police officers and obey the law. What existing literature lacks, however, is a thorough psychometric examination of procedural justice and police legitimacy with respect to convergent and discriminant validity.

Methods

The present study employs confirmatory factor analysis to examine convergent and discriminant validity and ordinary least squares regression to assess whether revised scales operate similarly to ones used in past research.

Results

Results suggest that the legitimacy construct is not internally consistent and that one of its subscales loads with the procedural justice items to form a single scale composed of both procedural justice and legitimacy items. Regression analyses indicate that the modified measures operate similarly to traditional ones.

Conclusion

It is urged that researchers pursue the theoretical and empirical development of procedural justice and police legitimacy in order to further the study of the normative model of policing.     

The effect of low self-control on perceived police legitimacy

Objective

The process-based model has influenced policing research for a number of years, but the role of individual differences on procedural justice judgments and perceived police legitimacy has received limited attention. The current study fills a void in the literature by examining the effect of low self-control on individuals’ procedural justice judgments and perceptions of police legitimacy.

Materials and Methods

The study uses a sample of young adults and estimates a series of OLS regression models to determine the effect of low self-control on the process-based model of policing.

Results

The findings demonstrate that low self-control is associated with unfavorable procedural justice judgments. In turn, procedural justice mediates the effect of low self-control on perceived police legitimacy. Low self-control, however, is also shown to condition the effect of procedural justice on legitimacy. Specifically, the effect of procedural justice on legitimacy becomes weaker with reduced levels of self-control.

Conclusions

These findings suggest that studies should account for self-control in process-based policing research and police policy should consider the impact of individual differences when implementing process-based strategies.     

Procedural justice during police-citizen encounters: The effects of process-based policing on citizen compliance and demeanor

Purpose

Theories of procedural justice have facilitated the development of a process-based approach to policing which emphasizes the fairness of the manner in which the police exercise their discretion. The study examines whether procedurally fair behavior by the police affects two types of citizen behavior during encounters: citizen disrespect toward the police and citizen noncompliance with police requests.

Methods

This study uses data from systematic social observations of police-citizen encounters to examine procedural justice factors on citizen behavior. Because of the reciprocal nature of police-citizen interactions, an instrumental variable is used in the statistical analysis to help address the causal relationship between police force and citizen disrespect.

Results

The statistical analyses find limited support for procedural justice factors. Two types of procedurally fair behavior by the police, police demeanor and their consideration of citizen voice, are significant in reducing citizen disrespect and noncompliance, respectively.

Conclusion

Procedural justice factors have limited and inconsistent impacts on the two types of citizen behavior, and future research should address the limitations of this study and evaluate process-based policing with more data from social observations of police-citizen encounters.     

Is the Effect of Procedural Justice on Police Legitimacy Invariant? Testing the Generality of Procedural Justice and Competing Antecedents of Legitimacy

Objectives

This study tests the generality of Tyler’s process-based model of policing by examining whether the effect of procedural justice and competing variables (i.e., distributive justice and police effectiveness) on police legitimacy evaluations operate in the same manner across individual and situational differences.

Methods

Data from a random sample of mail survey respondents are used to test the “invariance thesis” (N = 1681). Multiplicative interaction effects between the key antecedents of legitimacy (measured separately for obligation to obey and trust in the police) and various demographic categories, prior experiences, and perceived neighborhood conditions are estimated in a series of multivariate regression equations.

Results

The effect of procedural justice on police legitimacy is largely invariant. However, regression and marginal results show that procedural justice has a larger effect on trust in law enforcement among people with prior victimization experience compared to their counterparts. Additionally, the distributive justice effect on trust in the police is more pronounced for people who have greater fear of crime and perceive higher levels of disorder in their neighborhood.

Conclusion

The results suggest that Tyler’s process-based model is a “general” theory of individual police legitimacy evaluations. The police can enhance their legitimacy by ensuring procedural fairness during citizen interactions. The role of procedural justice also appears to be particularly important when the police interact with crime victims.

     

Procedural justice and police legitimacy: a systematic review of the research evidence

Objectives

We undertook a systematic review and meta-analysis to synthesize the published and unpublished empirical evidence on the impact of police-led interventions that use procedurally just dialogue focused on improving citizen perceptions of police legitimacy.

Methods

The systematic search included any public police intervention where there was a statement that the intervention involved police dialogue with citizens that either was aimed explicitly at improving police legitimacy, or used at least one core ingredient of procedural justice dialogue: police encouraging citizen participation, remaining neutral in their decision making, conveying trustworthy motives, or demonstrating dignity and respect throughout interactions. The studies included in our meta-analyses also had to include at least one direct outcome that measured legitimacy or procedural justice, or one outcome that is common in the legitimacy extant literature: citizen compliance, cooperation, confidence or satisfaction with police. We conducted separate meta-analyses, using random effects models, for each outcome.

Results

For every single one of our outcome measures, the effect of legitimacy policing was in a positive direction, and, for all but the legitimacy outcome, statistically significant. Notwithstanding the variability in the mode in which legitimacy policing is delivered (i.e., the study intervention) and the complexities around measurement of legitimacy outcomes, our review shows that the dialogue component of front-line police-led interventions is an important vehicle for promoting citizen satisfaction, confidence, compliance and cooperation with the police, and for enhancing perceptions of procedural justice.

Conclusions

In practical terms, our research shows the benefits of police using dialogue that adopts at least one of the principles of procedural justice as a component part of any type of police intervention, whether as part of routine police activity or as part of a defined police crime control program. Our review provides evidence that legitimacy policing is an important precursor for improving the capacity of policing to prevent and control crime.     

The influence of strain on law enforcement legitimacy evaluations

Purpose

While law enforcement officers have the state-sanctioned authority to use force as a way to ensure citizen obedience with the law, research has found that when private citizens evaluate the police as legitimate, they are more likely to comply with legal demands and cooperate with the police. Although procedural justice has shown to be a highly significant predictor of perceived police legitimacy, research has found other correlates of this outcome, including ethnic identity, low self-control and structural economic disadvantage. To date, no study has explored whether strain influences perceptions of the legitimacy of law enforcement.

Methods

A series of linear regression equations was estimated using survey data collected from a convenience sample of college students to determine the effect of strain on perceived police legitimacy.

Results

Even after controlling for procedural justice, strain exerted a negative and statistically significant influence on law enforcement legitimacy evaluations.

Conclusions

Police officers are encouraged to interact with citizens in procedurally just manners and to also consider people's strain levels when enforcing the law.     

Challenging the ‘invariance’ thesis: procedural justice policing and the moderating influence of trust on citizens’ obligation to obey police

Objectives

This paper examines the effects of a procedural justice policing intervention on citizens’ feelings of obligation to obey police. It examines whether the efficacy of procedural justice on citizens’ obligation to obey police may be contingent on citizens’ level of trust in police during a police–citizen encounter.

Methods

This research draws on survey data from the Queensland Community Engagement Trial (QCET). QCET was a randomized controlled field trial implemented by the Queensland Police Service. The trial exposed citizens to either a procedural justice experience (experimental condition) or standard police practice (control condition) during a random roadside stop. Survey responses were received from 1107 drivers in the experimental condition and 1655 drivers in the control condition.

Results

Compared to the control condition, the procedural justice condition yielded higher levels of trust in the police officer conducting the roadside stop. No differences in obligation to obey police were observed between the two conditions. Importantly, citizens’ level of trust in the officer moderated the effect of the intervention on obligation to obey police. Specifically, the procedural justice condition had a negative effect on obligation to obey for those reporting low trust in police. For those high in trust, the procedural justice intervention had a slight but insignificant positive effect on obligation to obey.

Conclusions

The findings suggest that procedural justice effects can vary between individuals; specifically, the findings reveal that procedural justice interventions can sometimes be counter-productive, depending on the level of trust a citizen exhibits toward police during an encounter. Police agencies should therefore be aware of potential counter-productive effects when implementing procedural justice in the field.

     

Promoting a culture of fairness: police training,procedural justice,and compliance

Objectives

Academics and practitioners alike are concerned about the potential “double-edged sword” of procedural justice. In the organizational context, procedural justice is expected to increase compliance with supervisors. However, blind, unthinking, or “hard” compliance with supervisors, may lead to anti-organizational behavior and misconduct. The present study examines the moderating effect of a police recruit cultural training program on the relationship between procedural justice and compliance with police supervisors. We expect that providing cultural training will moderate the relationship between procedural justice and “hard” compliance.

Methods

Participants were police recruits at the Queensland Police Academy who were randomly assigned to an experimental (Voice 4 Values) or control condition (business-as-usual training) upon entry into the academy. Recruits in both groups were surveyed pre- and post- training to capture perceptions of procedural justice and compliance with supervisors.

Results

Results suggest that procedural justice mattered less for predicting “hard” or unthinking compliance among the recruits who received the Voice 4 Values cultural training package, compared to those who did not receive the training.

Conclusions

We conclude that while procedural justice may be of interest to policing organizations, it is important that it is not used as a tool to encourage unthinking compliance. We find cultural training reduces the effect of procedural justice on unthinking or “hard” compliance.

     

Compstat in Australia: An analysis of the spatial and temporal impact

One of the major trends in policing sweeping across democratic societies since the mid-1990s is a management approach commonly known as COMPSTAT. Despite widespread global adoption, empirical evaluation of the impact of COMPSTAT lags behind popular accounts of its crime control benefits.

Purpose

This article evaluates the crime control impact of Queensland Police Service's version of COMPSTAT known as “Operational Performance Reviews” (OPRs).

Method

A mixed model analytic approach was used to assess the role of OPRs in explaining spatial and temporal variations in crime patterns across Queensland's 29 police districts.

Results

Analysis of the impact of OPRs on reported crime (specifically assaults, robberies and unlawful entries) suggests major differences between police districts, and that some districts are driving overall statewide crime reductions, whilst others confound positive effects of implementation of OPRs in Queensland.

Conclusions

The results demonstrate that the crime drop experienced throughout Queensland found in prior research (Mazerolle et al., 2007) is most likely attributable to a small number of police districts. The implication of these findings is that a number of districts could (and should) be called-upon during maturation of Queensland's OPRs to reduce specific crime problems in their districts and facilitate ongoing crime reductions across the state.     

Procedural Justice and Order Maintenance Policing: A Study of Inner‐City Young Men’s Perceptions of Police Legitimacy

There is tension between the core tenets of procedural justice and those of order maintenance policing. Research has shown that citizens’ perceptions of procedural justice influence their beliefs about police legitimacy, yet at the same time, some order maintenance policing efforts stress frequent stops of vehicles and persons for suspected disorderly behavior. These types of programs can threaten citizens’ perceptions of police legitimacy because the targeted offenses are minor and are often not well‐defined. Citizens stopped for low‐level offenses may view such stops as a form of harassment, as they may not believe they were doing anything to warrant police scrutiny. This paper examines young men’s self‐described experiences with this style of proactive policing. Study findings highlight that order maintenance policing strategies have negative implications for police legitimacy and crime control efforts via their potential to damage citizens’ views of procedural justice.     

Not by accident: An analytical approach to traffic crash harm reduction

Purpose

This study examines whether a problem-oriented approach used by police in Cincinnati, Ohio called the Crash Analysis Reduction Strategy (CARS) corresponded with a change in the number of traffic crashes that resulted in injuries after implementation onset. Under the CARS model, police developed tactics that focused on targeting high-risk driving behaviors, impaired drivers, and crash hotspot locations within the city.

Methods

Using a two-phase strategy we first assess local impact by examining injury-related traffic crash patterns at targeted locations. Second, we examine whether traffic crashes that resulted in injuries in Cincinnati significantly diverged relative to similar outcomes across a number of comparison sites.

Results

Difference-in-difference negative binomial regression analyses indicates that traffic crashes were significantly lower in Cincinnati - down roughly 5.7% to 10.3% in the post-intervention period - when contrasted with comparison sites.

Conclusions

Our findings suggest that comprehensive problem solving approaches can significantly reduce the risk of life changing events such as automobile crashes that result in injuries beyond traditional policing efforts that explicitly focus on crime and violence.     

Reporting violence to the police: Predictors through the life course

Scholarship focused on factors that influence police reporting has a long history in the literature. Yet we lack a complete understanding of how these factors differentially influence reporting by age.

Purpose

This paper aims to enhance our understanding of underreporting by investigating the relationship between reporting and age, and how this relationship differs by crime type. The study further investigates whether a variety of characteristics differentially influence reporting across the life course. Finally, the study asks how the nature of reporting varies by the victim's age.

Methods

National Crime Victimization Survey (NCVS) data were used to assess whether there are age-related differences in the factors influencing the rate and nature of police reporting.

Results

The findings suggest that the rate of reporting differs by crime type but that it generally increases throughout the life course. The influence of incident, victim, and offender characteristics on police reporting varies, not simply between juveniles and adults, but also between young and older adults. The proportion of incidents reported to police by the victim his/herself also continues to increase with age.

Conclusions

This suggests that disparities in police reporting cannot be reduced to juvenile-adult comparisons and should be studied across the full life course.     

Teaching procedural justice and communication skills during police–community encounters: Results of a randomized control trial with police recruits

Objectives

To describe and evaluate Chicago’s Quality Interaction Program (QIP) for police recruits. The training focused on procedural justice, interpersonal communication, decision-making, cultural awareness, and stress management during encounters with the public. Attention was given to emotions, empathy, and communication skills.

Methods

The QIP is an underutilized approach to police training that involves engaging recruits through applied case studies, role-playing scenarios, repetitive opportunities for practice, and individualized feedback. The impact of QIP training on 142 officers’ attitudes and behaviors was evaluated in a randomized control trial. Treatment and control groups were assessed through responses to self-reported questionnaires as well as research-coded videos that recorded officers during role-playing scenarios.

Results

The QIP did not change recruits’ attitudes toward procedural justice, nor did it impact their self-reported interpersonal communication skills. However, the program was effective at creating more respectful and reassuring behaviors during role-playing scenarios that were videotaped. The program also improved recruits’ decision-making during a scenario with rebellious youths and reduced officers’ reliance on force and arrest relative to controls.

Conclusion

The QIP initiative was instrumental in moving police training beyond “talking heads” to interactive adult education, while promoting a more sophisticated understanding of human dynamics during police–public encounters. The results, however, were mixed, due in part to a training academy environment that emphasized aggressive policing and officer safety. Thus, reform-minded agencies may need to rethink the totality of the training experience to achieve strong results.

     

The influence of forensic evidence on the case outcomes of homicide incidents

Objective

In spite of the growth of forensic science services little published research exists related to the impact of forensic evidence on criminal case outcomes. The present study focused on the influence of forensic evidence on the case processing of homicide incidents.

Materials and Methods

The study utilized a prospective analysis of official record data that followed homicide cases in five jurisdictions from the time of police incident report to final criminal disposition.

Results

The results showed that most homicides went unsolved (34.5% conviction rate). Only 55.5% of the 400 homicide incidents resulted in arrest of which 77% were referred to the district attorney. On the other hand, 94% of cases referred to the district attorney were charged. Cases were more likely to have arrests, referrals, and charges when witnesses provided information to the police. Suspects who knew their victims were more likely to be arrested and referred to the district attorney. Homicides committed with firearms were less likely to be cleared. The most noteworthy finding was that none of the forensic evidence variables significantly influenced criminal justice outcomes.

Conclusions

The study results suggest that forensic evidence is auxiliary and non-determinative for homicide cases.     

Testing Social Support Theory: A Multilevel Analysis of Recidivism

Purpose

Tests of social support theory have relied on aggregate crime rates as the outcome of interest, but such a focus ignores the potentially important macro-level processes and effects on individual-level behavior We thus perform the first multi-level investigation of social support theory.

Methods

Multilevel modeling is used to explore whether the two varieties of county-level social support - the presence of charitable organizations and AFDC expenditures - are associated with recidivism in a sample of Florida prison releasees.

Results

Results show that while social support explains little variation in individual-level recidivism, a combination of private and public social support may reduce the likelihood of reconviction for drug offenses.

Conclusion

Findings provide mixed evidence for the prospect that social support—whether governmental or nongovernmental—is associated with recidivism among recently-released inmates.     

Civil asset forfeiture, equitable sharing, and policing for profit in the United States

Purpose

Critics of asset forfeiture claim that forfeiture laws create financial incentives that inappropriately influence police behavior. The present study examines the relationship between measures of the financial incentive and legal burdens for civil asset forfeiture on federal equitable sharing payments to local law enforcement to determine whether police behavior is affected by different statutory incentives for forfeiture activity.

Methods

Using LEMAS and DOJ forfeiture data, this study addresses some of the limitations of previous research by using a multi-year average for forfeiture activity, an improved measure of financial incentives for law enforcement, and multiple measures of statutory burdens to law enforcement to determine the impact of forfeiture laws on forfeiture activity.

Results

Consistent with anecdotal reports and limited prior research, findings indicate that agencies in jurisdictions with more restrictive state forfeiture laws receive more proceeds through federal equitable sharing.

Conclusions

Results suggest that state and local law enforcement agencies use federal equitable sharing to circumvent their own state forfeiture laws when state laws are more burdensome or less financially rewarding to these agencies, providing additional evidence that police operations are influenced by financial incentives.     

Shades of blue: Confidence in the police in the world

Purpose

The present study tests the hypothesis that regime nature as a structural characteristic explains variations in public confidence in the police.

Methods

Combining five sources of data from 50 nations with 69,309 respondents, the current article extends the extant research by using hierarchical logistic regression analyses with ample sample sizes at both levels to test the hypothesis with a series of control variables.

Findings

In addition to the largely consistent findings from the individual-level predictors, the results show that that there is a U-shaper convex curvilinear relationship between the levels of democracy and confidence in the police. Residents in long-term stable authoritarian regimes as well as in long-term stable democracies display elevated levels of confidence in the police, whereas short-term or unstable authoritarian nations and nations in democratic transition have the lowest level of confidence in the police. Besides, confidence in the police is higher among citizens in nations with more government efficiency and is lower among residents of countries with higher homicide rates.

Conclusion

Regime nature is important in understanding confidence in the police. In addition, governments should make more efforts to promote their efficiency in order to win citizens’ support and they are expected to reduce homicide rates.
