A study of the interrelationships of several validity scales used in police selection

Validity scale data have received attention recently as providing valuable information about potential problematic police officer candidates. In this study, validity scale data from a number of selection instruments were obtained using 42 state police officer candidates. The scale used were the MMPI-2 L scale, the MMPI-2 K scale, the PAI Positive Impression Scale (PIM), the PAI Defensiveness Index (DI), the IPI Guardedness scale, the Hilson Life Adjustment Profile Lack of Candor scale, and the Inwald Survey 2 Denial of Shortcomings scale. Intercorrelations among the scales were developed and a factor analysis was performed. Factor analysis revealed two factors to be present. One is associated with the Hilson scales and is appropriately named guardedness or defensiveness. The other is associated with the MMPI-2 K scale and the PAI scales and is appropriately named social desirability. The MMPI-2 L scale loaded significantly on both factors and seemed to be the most general of the validity scales in terms of its characteristics. Implications of these analyses for police selection are discussed.     

Predicting Police Aggression: Comparing Traditional and Non-Traditional Prediction Models

Psychologists can help to reduce inappropriate aggressive behavior through careful screening of police officer candidates. The purpose of this study was to identify whether the IAT Reasoning Test (IAT), a measure of trait aggression, and a Monetary Delay Discounting Task (MDDT), a measure of behavioral control, could predict on-the-job police aggression better than the MMPI-2. We administered the MMPI-2, the IAT, and the MDDT to 85 police officers. Three prediction models were created using scores on the IAT and the MDDT, and scales from the MMPI-2. Model 1 included the IAT and the MDDT. Model 2 included MMPI-2 scales Hostility (HO), Overcontrolled Hostility (OH), and Anger (ANG). Model 3 included MMPI-2 scales Frequency (F), Hysteria (HY), and Psychopathic Deviate (PD). We found that Model 1 was the only predictor of supervisors?? ratings of on-the-job aggression, however, the predictive utility of this model was attributable primarily to the MDDT predictor. Based on these findings, we suggest that using measures of behavioral control during preemployment screening may help to identify potentially aggressive police officer candidates.     

An investigation of biographical information as a predictor of employment termination among law enforcement officers

Among the most important services that psychology can offer law enforcement is assistance in the selection of future officers. The usual contribution made by police psychologists centers on the elimination of applicatns who are mentally ill. However, due to increased behavior-generated police liability, psychologists must focus on ruling out applicants whose future behavior may result in departmental compromise for any reason. One method for forecasting police officer performance is by examining critical information in biographical data. This paper examined the predictive validity of biographical information for a sample of 2,965 police officer candidates. Results indicated that several biographical variables were significantly correlated with later police officer termination. However, results of regression analyses indicated that biographical variables alone accounted for limited variance in the prediction of police officer termination. These findings suggested that the use of biographical information as a sole determinant of police candidates was not supported and the use of additional sources of data would likely be required for practical forecasting purposes.     

The ‘us vs them’ mentality: a comparison of police cadets at different stages of their training

ABSTRACT

Any depiction of police culture includes a strong ‘us versus them’ element, but research has been unable to satisfactorily explain its development and evolution. In particular, very few studies have focused on the training period, between when an individual chooses a police career and his/her first day as an officer. A total of 1,979 pre-university students from seven colleges in Quebec (Canada) completed a self-administered survey where they had to answer general questions about the police followed by specific questions about four realistic videos of fictional police interventions involving use of force. Unsurprisingly, the analysis suggests that students in Police Technology tend to think they are more supportive of the police and the use of force than students in other programs. However, students in Police Technology increasingly indicate that the majority of people would report a more negative opinion than they have, suggesting that police candidates increasingly disidentify with the rest of the population.     

Individual and situational determinants of the use of deadly force: A simulation

The study of police use of deadly force is a complicated issue because of the scarcity of observed high-risk encounters in the field. The present research explores police shooting behavior in both life-threatening and non-life-threatening situations in a simulated environment. The results suggest that officers’ characteristics, such as race and gender, are not associated with officer shooting behavior. The one exception is that officers with less police experience show more restraint than veteran officers in responding to non-life threatening situations. Suspect demographics, such as race, gender, and age, show inconsistent relationships with officer shooting behavior. One consistent finding is that officers who show poor judgment, slow response, or poor marksmanship suffer a high casualty rate in reacting to life-threatening situations involving multiple suspects.     

An investigation into the usefulness of the MMPI and MMPI-2 in municipal and state police candidate selection

The Minnesota Multiphasic Personality Inventory (MMPI) and the later revision (MMPI-2) have been two of the most frequently employed instruments in the selection of law enforcement officers (Bartol, 1996). In this study, the following three sets of data were collected and analyzed: municipal law enforcement officer candidates tested with the MMPI, municipal law enforcement officer candidates tested with the MMPI-2, and state police trooper candidates tested with the MMPI-2. These three data sets were evaluated for their effectiveness at predicting “pass/fail” status on police candidate interview using multiple linear regression. A combination of subscales were found to be associated with classification as either pass or fail on interview.     

Examining the Use of Police in Schools: How Roles may Impact Responses to Student Misconduct

Prior research has suggested that the use of police in schools has resulted in negative outcomes for students; however, this line of research has failed to consider other factors that may influence an officer’s response outside of their mere presence. Over time, the roles and duties of police in a school setting have continued to expand as a result of social and political shifts in criminal justice and education policy. Paralleling this expansion has been the development of a more punitive school discipline environment where students are more likely to be suspended, expelled, a ticketed, and/or arrested. As these two separate bodies of research have been tangentially related, in this study, we use role theory as a guiding framework to connect these two bodies of research and examine how officers’ roles may influence their responses to student misconduct. Data was collected via an online survey distributed to a sample of commissioned law enforcement officers working in Texas schools. The survey included measures of officer roles as well as vignettes to assess how officers would respond to specific situations involving students. Results of this study suggest that an officer’s role may influence how they respond to student misconduct, and therefore, may be an important piece of information for both researchers and practitioners when looking to minimize the potential negative impacts of using police in schools. These findings related to officer roles are discussed in terms of both practice and future research, while considering the larger discipline environment of schools.     

An Investigation of Biographical Information as a Predictor of Employment Termination among Law Enforcement Officers

An important service that police psychology can offer law enforcement administrators is assistance in the selection of future officers. Police psychologists have traditionally focused on the identification of psychopathology and exclusion of applicants who were found to be mentally ill. The introduction of the Americans with Disabilities Act (1990) has changed what had been considered appropriate exclusion criteria because of the introduction of increased civil rights protections for persons with disabilities. At the same time, increasing civil liability for law enforcement departments in regard to officer misconduct has compelled police psychologist to evaluate potential for future misconduct by non-clinical means. The scientific examination of biographical data may be one method of establishing the relationship between officer candidate variables and future misconduct. This paper examined the predictive validity of biographical information for a sample of 2965 police officer candidates. Results indicated that several biographical variables were significantly correlated with later termination. However, results of regression analyses indicated that biographical variables alone accounted for limited variance in the prediction of police officer termination. The use of biographical information as a sole determinant of police candidate suitability was not supported and the use of additional sources of data would be required for effectual forecasting purposes.     

STREET-LEVEL DISCRETION IN POLICING

This article examines the consequences of a clash between police officers' expectations of street-level discretion and supervisors' constraints on such discretion. Two hypothesized consequences are examined: police officer alienation from the citizenry and police officer disaffection with the department. Both attitudinal data (from a survey of police officers) and behavioral data (from direct observation of police officers on patrol) are used. The data show some support for the hypothesis that disaffection with the department is a consequence of the discretion-constraint clash, but no support of alienation from the citizenry as a consequence. Rather, the data suggest that officers back away from discretion in situations where the public is perceived to be hostile and where supervisors reinforce that perception by active monitoring of police-citizen encounters.     

A PROACTIVE RESPONSE TO FAMILY VIOLENCE: THE RESULTS OF A RANDOMIZED EXPERIMENT

Recent British work has focused attention on preventing repeat victimization as part of an overall crime prevention strategy. Because domestic violence victims are among those most likely to suffer multiple victimizations, they are logical candidates for programs targeted at reducing repeat victimization.
This article reports on a joint law enforcement-social services approach to reduce the incidence of repeat domestic violence. The research design randomly assigned households reporting domestic incidents within two public housing police service areas in New York to receive or not receive a follow-up to the initial patrol response. (The follow-up visit was conducted by a police officer and a social worker.) In addition, housing projects in the same area were randomly assigned to receive or not receive public education about domestic violence.
Neither treatment produced a reduction in violence. However, households in projects that had received public education and households that received the follow-up visits were both more likely to report new violence to the police than households that did not receive the treatments. Moreover, the effect of the follow-up visit was most pronounced among households with more serious histories of violence. The results suggest that the interventions increased citizens' confidence in the ability of the police to handle domestic situations.     

The neo pi-r,inwald personality inventory,and mmpi-2 in the prediction of police academy performance: A case for incremental validity

The utility of personality inventories for predicting successful police officer performance is an important issue in the law enforcement employment selection process. The purpose of the present study is to evaluate the incremental validity of the Minnesota Multiphasic Personality Inventory (MMPI-2), the Inwald Personality Inventory (IPI), and the Revised NEO Personality Inventory (NEO PI-R) for predicting police academy performance of 79 recruits. Results indicate that each inventory contributes significantly to prediction of academic performance in the academy, while only the NEO PI-R predicts physical performance. The addition of the NEO PI-R to selection processes that already incorporate the MMPI-2 and IPI may be useful for enhancing prediction of police officer performance.     

Authoritariansim as indicated by measures of acceptance of authority and directiveness among police officers,students and townspeople

Conclusion Recently theory and scales measuring authoritarianism and cynicism of police have come into close scrutiny. In particular, Langworthy (1987:28,33) has concluded from his review of 21 empirical studies that police cynicism appears to have several different dimensions and that the “failure to detect cynicism or a factor closely related to it is a product of reliance on a very flawed instrument the Niederhoffer index.” To address that criticism of a faulty instrument, this research has utilized scales measuring directiveness and proauthority. For reasons of alpha coefficients, only the scores on the pro-authority scale were analyzed. Mean scores on the pro-authority scale between law officer, students, townspeople and police officers were not significantly different. When investigating variables relating to the high scores of proauthority of police officers, rank was statistically significant while age was not. For future research, separate population should be continued as well as random sampling. In addition, variables of age, sex, ethnic, rank and departmental/organizational dimensions should be explored.     

Problematic police performance and the personality assessment inventory

A relative newcomer to personality assessment in the area of law enforcement is the Personality Assessment Inventory, or PAI. Earlier MMPI research in the area of police selection has focused upon antisocial behavior, control of aggression, and validity indices, particularly the L scale. In this study T scores for 800 male and female police officer candidates on the PAI scales Negative Impression (NIM), Positive Impression (PIM), Antisocial-Antisocial Behaviors (ANTA), Antisocial-Egocentricity (ANTE), and Antisocial-Stimulus Seeking (ANTS) were used as predictors of the criterion variables Insubordination, Excessive Citizen Complaints, and Neglect of Duty. Highly significant coefficients were obtained for ANTE as a predictor of Insubordination and Excessive Citizen Complaints. For Neglect of Duty, two significant coefficients were obtained, one for ANTS and another for NIM. Discussion centered on the fact that egocentricity is a predictor of Insubordination and Excessive Citizen Complaints, and Neglect of Duty is related to stimulus seeking. Authors' Note: William U.

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.

     

Ethnicity, trust, and acceptance of authority among police officers

This article examines the factors that influence the willingness of police officers to comply with decisions made by police command staff. In particular, this research focuses on the extent to which officer ethnicity interacts with perceptions of procedural justice in influencing officer compliance. The data for this study were drawn from an anonymous mailed survey (n = 648) examining officer attitudes toward the complaint investigation process in one large municipal police department. Structural equation modeling demonstrates that ethnicity does influence officer compliance, but only weakly and indirectly. Latino/a officers are less likely to report trust in police internal affairs than White officers, and thus somewhat less likely report that they are willing to comply with command staff decisions. Other factors, such as morale, perceptions of procedural justice, and rank, prove to be much more powerful predictors of officer compliance than ethnicity.     

Police officers' perceptual distortions during lethal force situations: Informing the reasonableness standard*

Research Summary In 1989, the U.S. Supreme Court held that determinations about the constitutional appropriateness of police force usage—deadly or not—must be “judged from the perspective of a reasonable officer on the scene, rather than with the 20/20 vision of hindsight.” Although the Court's ruling established a clear standard for judging officers' actions (i.e., the perspective of a reasonable police officer on the scene), we know little about the sorts of factors that might frame the perspective of reasonable police officers during situations in which they apply force. This article presents the results of a study that examined 80 police officers' detailed accounts of how they perceived what transpired during 113 incidents in which they shot citizens. Respondents reported experiencing a wide range of sensory distortions, with the vast majority of officers reporting two or more distinct sorts. This study takes these findings as a point of departure to expand our understanding of what constitutes a reasonable officer's perspective during the tense, uncertain moments during which he or she makes the decision to employ deadly force. Policy Implications Given that officers are likely to experience multiple distortions during shootings, the findings have implications for civilian and police oversight policies. In particular, those responsible for reviewing police shooting incidents should take into consideration that officers' behavior will not always be based on the objective reality of what is occurring at the time they decide to pull the trigger, but rather an altered conception of it. Such an understanding is crucial to improving the image of police in certain communities and positively impacting citizen trust of, and satisfaction with, the police.     

Associations between MMPI-2-RF (Restructured Form) and Inwald Personality Inventory (IPI) Scale Scores in a Law Enforcement Preemployment Screening Sample

The MMPI-2 is widely used in assessments of police officer candidates. The MMPI-2-RF, composed of 338 of the 567 MMPI-2 items, is designed to measure the core clinical constructs assessed by the MMPI-2, but in a more psychometrically sound and efficient manner (Ben-Porath and Tellegen 2008/2011). Law enforcement comparison group data are embedded in the scoring software for the inventory, and reported in the User’s Guide for the MMPI-2-RF Police Candidate Interpretive Report (PCIR; Corey and Ben-Porath 2014). In the present concurrent validity study, conceptually based hypotheses regarding associations between MMPI-2-RF scales and scores on the Inwald Personality Inventory (IPI, Inwald et al. 1982; Hilson Research 2006), a test specifically designed to screen law enforcement officers, were tested with a sample of 277 male, full-time police officer candidates from four separate police departments of varying sizes examined after a conditional offer of employment was tendered. The majority of participants were Caucasian (69%), followed by African-American (27%), or Other/Mixed ethnicity (4%). Our hypotheses were largely borne out, lending support to the construct validity of the MMPI-2-RF and the ability of scores on the inventory to assess variables relevant to police candidate evaluations.     

College students’ perceptions of police use of force: do suspect race and ethnicity matter?

Incidents of police use of force continue to draw a considerable amount of attention from both researchers and the public alike. The purpose of this research is to examine the relationship between suspect race and ethnicity and perceptions of police use of force among college students. Using a vignette research design with manipulated independent variables, this study seeks to answer the question: Do suspect race and ethnicity affect college students’ perceptions of police use of force? Three vignettes were developed regarding an incident in which an encounter between a suspect and a police officer resulted in the officer using force. College students were randomly assigned to one of the three vignettes and were asked to complete a questionnaire. Results indicate that although suspect race and ethnicity do not predict perceptions of police use of force among college students, there are significant respondent race and gender effects. Male and white respondents are significantly more likely to perceive police use of force as justified compared to female and non-white respondents. The policy implications of these findings for police-citizen interactions are discussed.     

Demeanor,sex, and race in police processing

Recent increases in arrests of women have stimulated much controversy about the causes and extent of female crime and created much speculation about the differential treatment of female offenders by police officers. This article reports an empirical study of police processing of female offenders. During September–December 1978, 282 questionnaires were completed by police officers and detectives in a large, metropolitan area in a southeastern state. Each officer was asked to indicate a police decision in five hypothetical situations which varied by types of offense, race of the offender, sex of the offender, and demeanor of the offender. An analysis of the responses of the police officers indicates that decisions of police are not contingent on the sex and race of the offenders. The major variables in determining how police officers will respond are the nature of the offense and the manner in which the offender behaves when confronted by the officer.     

Perceptions and experiences of people with mental illness regarding their interactions with police

This study examined the perceptions and lived experiences of people with mental illness in relation to their interactions with the police. A community-based participatory research approach was used and a procedural justice theoretical perspective guided the study. In-depth, semi-structured interviews were conducted by peer researchers with 60 people with mental illness who had interacted with the police and were living in Metro Vancouver, Canada. Among the study participants, contact with the police was frequent and occurred under a diverse range of circumstances. The majority of participants perceived being treated in a procedurally just manner by the police officer(s) who were involved in their most recent interaction. Almost three-quarters (n = 43, 72%) of participants were generally satisfied with how the police officer(s) had handled their most recent interaction. The slight majority of participants (n = 30, 51%) rated their previous contacts with the police as a positive experience overall, with 32% (n = 19) indicating that their previous interactions with the police were negative life experiences. The findings paint a more balanced picture than that which is often portrayed by the media. Emphasizing a procedural justice framework for police handling of situations involving people with mental illness is a vital step toward improving how these interactions are experienced and perceived.
