A three-year follow-up of the performance of a class of state police academy graduates using the MMPI-2

Research has demonstrated the utility of the MMPI-2 in identifying good and poor performance, dissatisfaction, termination, low performance ratings, unsatisfactory and satisfactory criterion groups, problematic behavior, corruption, and aggression. There is much research to suggest that certain patterns of responding to this measure by officer applicants predict job performance behaviors that supervisors and police executives view unfavorably. This study illustrates the fact that variables which are likely to predict police performance are less obvious and more subtle. Discussion centers on repression and underlying hostility.

The MMPI-2 and statisfactory police academy performance: Differences and correlations

The Minnesota Multiphasic Personality Inventory (MMPI) and its later revision (MMPI-2) have been the most frequently employed psychological instrument in the selection of law enforcement officers (Bartol, 1996). In this study, state police trooper cadets were given a broad number of measures including the MMPI-2 prior to academy admission. Their performance at the police academy was then analyzed and related to their performance on the MMPI-2. Using step-wise multiple linear regression. Hy3 and Sc4 scores produced significant negative correlation’s with academy final grade point average. Student’s unpaired 1-tests between successful and unsuccessful cadets revealed differences between the groups for several MMPI-2 subscales including, but not limited to, K, MA, and SI, Lastly, logistic regression revealed no single subscale, or combination of subscales, which significantly predicted classification of the cadets as either successful or unsuccessful based on their MMPI-2 scores alone.

Comparison of the MMPI-2 and Niederhoffer Cynicism Scales for a Sample of police academy trainees

This study compared the Niederhoffer Cynicism Scale, as a less costly alternative, to the MMPI-2 measure of cynicism. Data were collected on both scales from a sample of male and female police academy trainees to compare reliability and construct validity. Subgroup analyses by race and sex yielded comparable Cronbach alpha estimates for minority (.71) and majority (.83) males to MMPI-2 norms. The Niederhoffer reliability values were marginally smaller (.73 to .77) but within the acceptable range. Construct validity correlations between both scales were significant for minority and majority males. However, sample size was too small for both minority and majority females groups to use appropriate statistical techniques to determine reliability or validity. Continued use of the Niederhoffer is recommended for minority and majority males.

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.

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.     

Use of the MMPI-2 to predict the employment continuation and performance ratings of recently hired police officers

The MMPI-2 is one of the most frequently employed instruments for the selection of police officers. Serafino and Serafino (1997) collected data which involved information about employment continuation and ratings by supervisors of 32 police officers who had recently been hired and who had been given the MMPI-2 during the hiring process. In this study, the Paranoia Obvious (Pa) and Paranoia Subtle (Ps) scales proved to be the significant. Pa Subtle correlated with removal whereas Pa Obvious correlated with rating. Higher scores on Pa Subtle correlated significantly with being removed from the job, whereas low scores on the Pa Obvious correlated with higher ratings of performance by supervisors. Discussion of the results involved the fact that Subtle Pa scores would suggest paranoid tendencies not easily detected during the interview. Since most high Pa Obvious individuals would have been eliminated in the hiring process, expression of this tendency was at a low level after being hired but if present resulted in low ratings. Significant predictors were noted to be very much a function of the type of criterion variable employed in the study.     

Prediction of police officer performance with the inwald personality inventory

The Inwald Personality Inventory (IPI) was administered to police officer applicants during pre-employment psychological screening. Scores were used to predict applicant performance, as rated by supervisors, after one year of active duty and change in performance over a 10-month period. Performance was significantly predicted by IPI scales, including Family Conflicts, Guardedness, and Driving Violations. These findings support the predictive validity of the IPI and identify specific characteristics of applicants that may influence performance in the field.

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.     

Use of the MMPI-2 in the treatment of offenders

The MMPI-2 is among the most frequently relied upon inventories for personality assessment. The test is utilized across a variety of nonforensic settings (e.g., psychiatric inpatient and outpatient) as an aid in formulating treatment plans, assessing treatment progress, and measuring treatment outcome. The MMPI-2 can also be utilized in forensic settings in a manner similar to its use in other settings, such as identifying treatment goals and evaluating treatment efficacy. Various MMPI-2 scales can identify an individual's treatment needs, reveal potential obstacles to treatment, and serve as a measure of treatment efficacy. Such information can be very helpful to the clinician in formulating or modifying a course of treatment for offenders. This article provides an overview of the use of the MMPI-2 in treatment planning and describes the relation between scores on the validity, clinical, and various supplementary scales and treatment-related issues.     

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.     

An examination of stress hardiness, dysphoria, and anger among police recruits exposed to stressful police academy training

This study examined whether stress hardiness moderates the relationship between stress and anger during stressful police academy training. It was hypothesized that stress hardiness alters the strength of the relationship between stressful circumstances and anger. The study of stress resistance is an important area of study as stress has been linked to behavioral problems (e.g., absenteeism from work), emotional problems (e.g., depression), and physical problems (e.g., coronary heart disease). This research was conducted as part of the doctoral dissertation requirements of Billy J. James at Walden University, Minneapolis, MN     

Differences in personality and mental state between suspects and witnesses immediately after being interviewed by the police

Abstract

There is increased recognition that people interviewed by the police are often psychologically vulnerable due to modest intelligence, mental health problems, disturbed mental state, and personality problems. The current study aimed to investigate differences in the mental state and personality between suspects and witnesses. The participants were 78 individuals (47 suspects and 31 witnesses) who had been interviewed by the Icelandic police. They were assessed psychologically immediately after the interview with the police was completed. Significant differences emerged between the two groups with the suspects being more depressed, hopeless, compliant and personality disordered than the witnesses. Four of the suspects claimed to have made a false confession to the police due to their immediate need or psychological problems.     

Coping,confidence, and change within the academy: a longitudinal look at police recruits

This study is based on surveys of police recruits representing four agencies across the United States. The recruits were surveyed at the beginning and end of their academy training and asked about coping strategies and the confidence they had in performing their jobs. Coping shifted significantly over time, with recruits utilizing task-oriented and outreach strategies less frequently at the end of the academy than at the beginning. Avoidance coping strategies were used more frequently by recruits at the end of the academy than at the beginning. Slight changes were also found in the influence of these strategies on job confidence over time, with avoidance coping having a stronger influence in the beginning of the academy than at the end. The role of demographic factors on coping was largely invariant over time, with only slight differences detected. Implications for policy and research are also discussed.     

Design of an algorithm to identify persons with mental illness in a police administrative database

North American police maintain a database to track events and information related to their involvement with the public that contain a series of electronic caution/dependency flags attached to an individual's name for internal communication. To identify persons with mental illness in a police administrative database, an algorithm was developed that was composed of (a) caution/dependency flags, (b) addresses, and (c) key search words indicative of mental illness. Based on the level of confidence of the algorithm, persons with mental illness (PMI) were then assigned to one of three categories: Definite, Probable and Possible PMI. Results for 2000 include the sociodemographic characteristics of PMI and non-PMI in the database. The mean number of contacts, types of interactions, re-involvement with a year, charges and dispositions are described. The algorithm provides a cheap, quick method to identify PMI for North American police. It enables police to monitor the effectiveness of pre-arrest diversion programs and allows researchers to analyze questions of criminalization and mental illness.     

Use of solid-phase double-antibody radioimmunoassay to identify species from small skeletal fragments

Protein radioimmunoassay (pRIA) offers the potential to identify species in small skeletal fragments submitted as forensic evidence. The technique consists of protein extraction followed by a solid-phase double-antibody radioimmunoassay using controls of antisera (raised in rabbits) and radioactive (iodine-125) antibody of rabbit gamma globulin (produced in donkeys). Species determination results from evaluation of radioactivity uptake. To demonstrate the potential of this technique, six known bone samples (three human and three nonhuman, including one from a deer [Odocoileus virginianus]) were submitted for blind analysis. pRIA correctly distinguished the human from the nonhuman samples. Using 200 mg or less of each sample, species of the deer specimen was identified correctly, given the choices of cow, deer, dog, goat, and pig.     

Use of the MMPI-2 Restructured Clinical (RC) Scales in Detecting Criminal Malingering

The purpose of the present study was to assess the effects of criminal malingering on the MMPI-2 Restructured Clinical (RC) scales. Sixty undergraduate students were given the MMPI-2 twice. One administration was conducted according to the MMPI-2 manual, and the other was given with a special set of malingering instructions specific to a prison setting. The two MMPI-2 profiles for each participant were scored for both the Basic and RC scales. Eight participants were eliminated from the data analysis due to validity (VRIN or TRIN) concerns. Data from the remaining 52 participants were analyzed using a 2 × 2 repeated measures ANOVA. Results showed that, as expected, the participants achieved higher MMPI-2 scores in the malingering condition. Also, participants achieved higher scores overall on the Basic scales and a significant interaction showed that participants achieved higher scores on the Basic Scales in the malingering condition than on the RC scales in that condition. These results supported prior research, indicating that malingerers produce elevated RC profiles. However, the present results also suggest that the Basic scales may be more effective in actually detecting malingerers, mainly due to the much lower ceiling on the RC scaled scores. Further implications of these findings for research and clinical work are also discussed.     

The state of the nation: diversity and the British legal academy

In this short piece, I set out briefly what we know about the challenge of diversity in the legal academy from existing scholarship. That field, in the UK at least, is sparse. I then go on to present a snapshot of the legal academy using data from the Higher Education Statistics Agency (HESA). I do this as the start of a much larger project on diversity and the legal academy that I plan to undertake over the next year. My argument is rather simple. The diversity of the legal academy reflects neither the diversity of our law student bodies nor the diversity of the wider population. Such diversity is vital for a number of reasons. My hope is that this piece can be the start of a dialogue on an important and largely ignored topic, and that further research will be done in this area.     

“Being a topic expert is not sufficient”: a mixed-method analysis of teaching dynamics at the Tasmania police academy

ABSTRACT

In unpacking the results of an in-depth longitudinal program evaluation, and in light of literature on police education, we analyse the various elements that contribute to the dynamic delivery of teaching in a police academy. A mixed-method analysis of 5 years of student evaluations enriched with the views of police education managers, coordinators, and educators provides an overview of the circumstances in which educators teach police recruits, the dynamics which unfold when teaching police, and the necessary characteristics for educators when addressing a police audience. This analysis positions the Tasmanian model of police education as an interesting case study in the midst of relatively critical literature about police education, and even more cautious studies on higher education partnerships in policing.
