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.     

The impact of situational factors, officer characteristics, and neighborhood context on police behavior: A multilevel analysis

While a considerable number of studies had been conducted to examine the effects of various variables on police behavior, very few studies had simultaneously analyzed factors that accounted both for police coercive and noncoercive behaviors. Equally limited is the research on the influences of officer characteristics and neighborhood context on police behavior controlling for all individual situational factors. Using observational and survey data collected by a large-scale project and hierarchical linear modeling techniques, this study assessed the effects of situational, officer, and neighborhood variables on police coercive and noncoercive actions, as well as the cross-level effects between these variables. Findings showed that situational characteristics played a strong role in determining officer coercive behavior, but not noncoercive activities. Similarly, officer-level predictors explained better officers' variation in coercive behavior than noncoercive behavior. Meanwhile, socially disadvantaged neighborhoods were more prone to receive coercive activities than were other neighborhoods. Implications for policy and future research are discussed.     

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.     

Bad cops

Research Summary Police scholars and public policymakers throughout generations have sought to identify reliable correlates of police misconduct. Despite these efforts, general statements as to the etiology and epidemiology of police misconduct remain inconclusive, in part because of the inconsistent definitions of misconduct and the difficulty of obtaining the data required to make such statements. This research attempts to fill these gaps through a comparison of the personal and career histories of all 1,543 officers who were involuntarily separated from the New York City Police Department (NYPD) for cause during 1975–1996 with a randomly selected sample of their police academy classmates who served honorably. The study uses confidential NYPD files as its major data sources, which include extensive biographical and career information. The study finds that career‐ending misconduct rarely occurs in the NYPD and that the types of misconduct do not match well with existing definitions. Several factors emerge as significant predictors of misconduct, including officer race, minimal education, records of prior criminality and prior poor employment, failure to advance in the NYPD, and histories of citizen complaints. Policy Implications This study shows that existing definitions of police misconduct are difficult to apply to actual cases of police malpractice, which leads the authors to create a new eight‐category classification scheme. The rarity of misconduct, especially on‐duty abuse, confirms prior research indicating that most police officers do their jobs without engaging in serious malpractice. These findings suggest that the NYPD has become better behaved as it has become more diverse along race and gender dimensions and that the link between black officers and misconduct might be explained by persistent “tokenism.” The findings related to race have important implications for continued efforts to build racially representative police departments. Personal history findings highlight the importance of conducting background investigations that disqualify candidates with arrest records and employment disciplinary histories, whereas the inverse relationship between college education and misconduct provides strong support for continued emphasis on pre‐ and post‐employment educational requirements.     

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.     

Police officer performance appraisal and overall satisfaction

Although the level of dissatisfaction with police officer performance appraisal systems in many agencies is substantial (Hughes, 1990; Lilley, 2002), a recent nationwide survey of six hundred police organizations indicated that overall satisfaction was significantly higher among agencies with greater levels of community policing implementation (Lilley & Hinduja, 2006a). Given that research has suggested that dissatisfaction with the appraisal process may impact future employee performance and retention (Daily & Kirk, 1992; Deming, 1986), the focus of this analysis was to examine differences among police agencies that might explain this variation. Utilizing structural equation models, results indicated that agencies with a high level of community policing implementation were not automatically associated with increased satisfaction. Rather, these organizations differed from their more traditional counterparts with regard to evaluation procedure in that they provided substantially more training to raters, emphasized the use of performance appraisal for officer development, and evaluated a broader range of performance criteria.     

Situational factors and police use of force across micro-time intervals: A video systematic social observation and panel regression analysis

The current study analyzes police use of force as a series of time-bound transactions between officers, civilians, and bystanders. The research begins with a systematic social observation of use-of-force events recorded on police body-worn cameras in Newark, New Jersey. Researchers measure the occurrence and time stamps for numerous participant physical and verbal behaviors. Data are converted into a longitudinal panel format measuring all observed behaviors in 5-second intervals. Panel logistic regression models estimate the effect of each behavior on use of force in immediate and subsequent temporal periods. Findings indicate certain variables influence use of force at a distinct point in time, whereas others exert influence on use of force across multiple time periods. The most influential variables relate to authority maintenance theoretical constructs. This finding supports prior perspectives arguing that police use of force largely results from officer attempts to maintain constant authority over civilians during face-to-face encounters. Nonetheless, a range of additional variables reflecting procedural justice, civilian resistance, and bystander presence significantly affect when police use force during civilian encounters. Results provide nuance to theoretical frameworks considering use of force as resulting from the interplay between officer and civilian actions and reactions.     

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.     

Predicting the employment of minority officers in U.S. cities: OLS fixed-effect panel model results for African American and Latino officers for 1993, 1996, and 2000

Using panel data collected on a representative sample of police departments serving populations of 25,000+ residents across the country in 1993, 1996, and 2000 (N = 281), fixed-effect panel models were used to assess the influence of environmental and institutional variables on the hiring of African American and Latino officers. The primary findings were that the presence of a substantial minority population was among the most important predictors of minority officer employment in city police departments. The presence of a Latino mayor and the presence of an African American or a Latino police chief were also significantly associated with increased minority police officer employment. Additionally, no evidence was found to suggest a detrimental impact caused by different minority groups competing with each other for limited police employment resources. Implications for future research are discussed in some detail.     

Social ecology and police discretion: The influence of district crime, cynicism, and workload on the vigor of police response

This study provided a partial test of Klinger's (1997) postulations on the ecological correlates of police vigor using data drawn from the Project on Policing Neighborhoods (POPN). Klinger's theory hypothesized that a form of police behavior he called vigor would vary inversely with district crime levels because officers would be more cynical of residents, view crime as normal, perceive victims as less deserving, and have less time to devote to calls in high crime districts. Although data limitations precluded a full test, the current study examined two of the four mediating variables (officer cynicism and district workload) and their influence on the crime/vigor relationship. Findings revealed variables other than those examined might mediate the effect of district crime on vigor or the relationship between district crime and vigor might be spurious. Implications for future research and theoretical development are discussed.     

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.     

The theory of planned behavior and policing: how attitudes about behavior,subjective norms,and perceived behavioral control affect the discretionary enforcement decisions of police officers

This research used qualitative methods to investigate police officer decision-making processes within the context of the theory of planned behavior from the discipline of psychology. Interviews with police officers were conducted to elicit how the constructs of attitudes about enforcement behaviors, subjective norms, and perceived behavioral control manifest themselves in a policing context and how they affect the enforcement decisions that police officers ultimately make. The results indicated that officer attitudes about enforcement behaviors impact the decisions officers make with the caution that the impact of these attitudes varies across varying situational contexts. In terms of subjective norms, officers were primarily concerned with supervisor expectations more than the expectations of coworkers or the community in general. Officer decisions are also impacted by perceived limits on their discretion with these perceived limits being largely conditioned by offense seriousness. Theoretical implications of the findings and directions for future research are discussed.     

The verdict is in: how did they decide? Using drivers’ self-reported data to understand officers’ decision making during traffic stop encounters

ABSTRACT

In the United States, traffic stop is the most common form of police-citizen encounter, and for many citizens, it is the only way they will ever interact with the police. The frequency of traffic stop encounters has therefore attracted a significant research interest. In the past several years, researchers have attempted to explain the dynamics of these interactions, with the hope to change attitudes and influence policy formation. To supplement the efforts of previous researchers, the current effort analyzed self-reported data from citizens to understand police decision making at three decision points during traffic stop encounters. Specifically, the present study aims to answer three questions: what variables predict whether an officer will let a citizen go without doing anything or decide to do something? If the officer decides to do something, what influences the officer’s decision to choose an outcome over others? What are the drivers of use of force in traffic stop encounters? Results from the regression models suggest that reasons for the stop, verbal assault, officer and suspect characteristics are important predictors of police decision making behavior during traffic stop interaction. The findings have serious implications for developing better police-citizen relationships as well as improving public attitudes toward the local police.     

Women Police

Abstract

This study investigated the use of force by and against women police officers using survey data from a large sample of female and male officers in six departments. Results suggested that female officers and same-gender female-female officer pairs used less force, and were less likely to use physical force, in police-citizen encounters when compared to their male counterparts. There was no evidence supporting the proposition that citizens used less force against female officers compared with male officers. In fact, the findings indicated that citizens used significantly more force against female officers relative to male officers in domestic calls. Although female officers were more likely to engage in underpredicted policing; that is, use less force than the situation would normally dictate, underpredicted policing was not related to an increase in the likelihood of officer injury. Implications for women officers, police use of force, and the institution of policing are discussed.     

The relationship between Body Mass Index and abnormal psychological and personality variables

The Body Mass Index (BMI) was created in order to classify individuals into body weight categories ranging from below normal to very obese, depending on the individual’s weight and height. The Body Mass Index has been identified as a marker for psychological issues such as self-control, self-esteem, depression, and anxiety. This study used a data matrix composed of a sample of 2,506 police officer candidates. The BMI’s were calculated and correlated with 343 personality variables, including the MMPI-II and the Personality Assessment Index. The results indicated a total of 87 significant correlations, 20 at the .05 level and 67 at the .01 level. Despite the fact that many of the correlations were small, the large number of correlations indicates a significant relationship between BMI’s and individuals with problematic psychological and personality characteristics. Discussion centers upon explanations of the relationship between the Body Mass Index and various psychological concepts.     

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.     

Traffic Stop Encounters: Officer and Citizen Race and Perceptions of Police Propriety

The continued legacy of racism and discrimination contribute to racial and ethnic differences in attitudes about the police. This research investigates citizen reports of proper police behavior during traffic stops to understand how officer/citizen race and ethnic pairs influence reports of impropriety. Analysis of 6,301 citizen reports of traffic stop encounters with the police from a unique national survey reveals that net of other important explanatory variables, African-Americans are less likely than whites to report proper police behavior when they encounter officers of any race. In addition, citizen reports indicate that the white/black and black/white officer/citizen encounters are significantly less likely to result in a report of proper police behavior than the white/white officer/citizen pairing. The results show limited support for the importance of citizen race and officer/citizen pairs in determining perception of police behavior.     

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.
