A re-examination of the MMPI-2 aggressiveness and immaturity indices in law enforcement screening

This study reports an analysis of Bartol's (1991) Immaturity Index and Hargrave and associates' (1988) Aggressiveness Index as a measure of police conduct. The correlations between the supervisory ratings and the Immaturity and Aggressiveness indices were examined for 1020 law enforcement officers. The results showed that Immaturity Index was related to termination for failure to complete training and insubordination. The Aggressiveness Index was related to a termination for failure to complete training and several other problematic police behaviors, but was not found to be specifically linked with acts of aggression. Implications for using these two indices in law enforcement selection are discussed.

Amended Final-offer Arbitration Outperforms Final-offer Arbitration

Amended final-offer arbitration (AFOA) has been developed asan attractive alternative mechanism to final-offer arbitration(FOA). Under AFOA, more reasonable offers win, but the outcomeis determined by the loser's offer and the arbitrator's value.In AFOA, disputants making extreme offers are penalized, therebyencouraging compromise. This article compares the theoreticaland behavioral properties of AFOA and FOA. Controlled laboratoryexperiments indicate that AFOA significantly outperforms FOA,generating substantially greater prearbitration settlement.Consistent with theoretical predictions, offers converge underAFOA; however, FOA offers neither converge nor are consistentwith theoretical predictions. This work suggests practitionersshould consider adopting AFOA over FOA.     

Autonomy,Belongingness, and Engagement in School as Contributors to Adolescent Psychological Well-Being

Self-determination theory emphasizes the importance of school-based autonomy and belongingness to academic achievement and psychological adjustment, and the theory posits a model in which engagement in school mediates the influence of autonomy and belongingness on these outcomes. To date, this model has only been evaluated on academic outcomes. Utilizing short-term longitudinal data (5-month timeframe) from a set of secondary schools in the rural Midwest (N = 283, M age = 15.3, 51.9% male, 86.2% White), we extend the model to include a measure of positive adjustment (i.e., hope). We also find a direct link between peer-related belongingness (i.e., peer support) and positive adjustment that is not mediated by engagement in school. A reciprocal relationship between academic autonomy, teacher-related belongingness (i.e., teacher support) and engagement in learning is supported, but this reciprocal relationship does not extend to peer-related belongingness. The implications of these findings for secondary schools are discussed.

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.

Compulsive traits and police officer performance

As a general rule, pathologies tend to impair job performance. In a study involving performance criteria and the Personality Assessment Inventory in a sample of Louisiana police officers (N=800), OCD characteristics correlated significantly in a negative direction with several performance criteria, such as involvement in an on-duty or off-duty at fault moving violation, number of on-duty or off-duty at fault moving violations, any citizen complaints regarding unprofessional conduct, number of unprofessional conduct, and accusation in any way of racially offensive conduct, behavior, verbalization, or complaints. It has been found that the traits of obsessive-compulsive disorder, in moderation, may actually improve performance in police officers. This agrees with the Yerkes-Dodson law, which states that peak performance occurs when a person experiences mild to moderate levels of stress.

Police psychology: The influence of Daubert and its progeny

In the current legal atmosphere, any practicing professionals, including police psychologists, may expect to have their decisions challenged in court. If such a challenge is not met, it may have a disastrous financial and reputational impact for both the psychologist (and other expert consultant) and the employer or contractor by whom the psychologist has been retained. The rules for expert witness qualification throughout the nation have been very strongly effected by the introduction of the Federal Rules of Evidence in 1975 and subsequent case law, particularly theDaubert, Joiner, andKumho Tire Supreme Court decisions. This article examines the history of the development of theDaubert Standard and proposes principles for potential expert witnesses in order to minimize the likelihood of aversive consequences, such as disqualification or malpractice accusations.

The MMPI-2 L scale as a tool in police selection

The MMPI has been used extensively in the selection of law enforcement personnel. Because police officer candidates have been preselected, however, individuals with obvious mental disturbance have been screened out of the candidate pool before evaluation. It is necessary to search for more subtle variables to serve as predictors of unsatisfactory future performance. The L scale is a subtle variable which can suggest potential for problematic behavior. The value of the L scale in the selection process is discussed. Authors' Note: William U. Weiss, Ph.D., is professor of psychology.
