Effects of the NICHD Protocol Training on Child Investigative Interview Quality in Korean Police Officers

This study was conducted to determine, by comparing pre- and post-training interview of 18 Korean police officers, whether training in use of the NICHD Protocol improved the quality of investigative interviews of allegedly abused child victims. Results showed that Korean police officers more often followed the Protocol structure -they introduced themselves, explained the ground rules, and conducted episodic memory training-after they had been trained. Moreover, police officers used approximately three times as many desirable prompts (such as invitations and facilitators) and fewer suggestive prompts in interviews conducted after as opposed to before the training. Invitations elicited approximately four to seven times more details on average than the least productive prompts. These results confirmed that the NICHD Protocol is effective when used to interview alleged child abuse victims in East Asia.     

Training Police Investigators to Interview to Detect False Intentions

This study is the first to investigate police investigators’ adherence to, and the effectiveness of, a training program for detecting true and false intentions. Experienced police investigators (N = 53) were either trained or not trained in how to interview to discriminate between true and false intentions. All investigators interviewed mock suspects (N = 53), of which half lied and half told truth about their intentions. Both subjective and objective measures showed that the trained investigators interviewed in line with the training received. That is, a large proportion asked about the planning of the stated intentions. Noteworthy, none of untrained investigators reported to have posed such questions for strategic purposes. The trained investigators reached a higher detection accuracy level (65 %) than their untrained colleagues (55 %), however not significantly. Given that the investigators adhered to the training, this training package is a viable starting point for developing more effective training programs.     

A comparative study of the attitudes of Urban,Suburban and Rural Police Officers in New Jersey regarding the use of force

This article examines the attitudes of sample populations of urban, suburban and rural police officers in New Jersey in regard to a hypothetical use of force scenario. The aim of the study is to identify similarities and differences in the perceptions of officers who are faced with the same type of hypothetical situations but who are exposed to different training, procedural and environmental factors. Police officers in the United States receive different types of training in each state that might influence their attitudes towards the use of force. A pilot study was conducted comparing two urban police departments from two different states and showed some differences in the attitudes of the surveyed officers. To further explore these differences, a more refined look at three police departments in one state (New Jersey) was conducted as part of a doctoral dissertation of the lead author. Research questions are aimed at identifying the differences in the frameworks for the justification of force based on a host of variables. The research questions stipulated that there will be some significant differences in attitudes towards the use of force by the officers, based on physical location of the communities they police. The findings of the study identified additional factors that might influence the officers’ attitudes. Twelve focus groups, four at each of the sites, were analyzed and it appears that there may be a geographic and demographic influence on how the officers respond to the scenario.     

The Cognitive Interview: novice police officers' witness/victim interviewing practices

Abstract

The objective of this study was to investigate novice police officers’ witness interview practices immediately post investigative interview training (known as PEACE) with reference to the eight Cognitive Interview (CI) components taught. Forty-eight UK police officers took part as interviewers. Forty-eight undergraduates participated as mock witness; they viewed a non-violent crime video and 2 days later were individually interviewed by a police officer. Interviews were recorded and rated for officers’ application of the CI procedure.

Despite having recently completed the only training available to them no officer applied or attempted to apply the CI procedure in its entirety. However, some of the individual CI components were applied more frequently than others. This study provides a unique insight into the interviewing practices of some of the least researched, least experienced, and least trained investigative interviewers who, nonetheless, conduct witness interviews on a daily basis. The emergent picture suggests that either the CI procedure currently taught to novice police officers is too complex at so early a stage in their police career and/or that the current training may be insufficient to equip them with the skills necessary to effectively apply the procedure.     

Brief Mental Skills Training Improves Memory and Performance in High Stress Police Cadet Training

Psychological performance training has been shown to mitigate the negative effects of stress for police officers. We contributed to this body of evidence using techniques in breathing, mental performance imagery, and attentional focus. One group (experimental) of police academy cadets was trained in these techniques to deal with the stressful event of being sprayed with oleoresin capsicum (OC). Their physiological and behavioral responses to the event were compared to a control group of cadets. The results showed the experimental group demonstrated significantly better memory recall of salient aspects of the OC spray event and that cadets from both groups using controlled breathing during the event scored significantly higher in memory recall. Several trends were found that further suggested the effectiveness of psychological performance training. While heart rate increased from baseline to pre-OC and post-OC measures across groups, there were no group differences at these time points. Our findings add to the growing body of literature on psychological skill training effects on tactical performance and are notable for results of enhanced performance occurring with relatively brief training in the psychological techniques. Because of the ecological design, the findings should generalize to other high stress encounters in policing.     

An examination of the questioning styles of police officers and caregivers when interviewing children with intellectual disabilities

Purpose. This research provided a detailed analysis of the types of questions and verbal strategies used by police officers and caregivers when interviewing children with intellectual disabilities about events. Method. Twenty eight children aged 9 to 13 years with a mild or moderate intellectual disability participated in a staged event at their school. Each child was then interviewed on separate occasions by the child's primary caregiver and by a police officer who was authorized to conduct investigative interviews with children. Results. While the approach used by the police officers was broadly consistent with best‐practice recommendations (i.e. their interviews contained few leading, coercive or negative strategies), they frequently interrupted the child's account and used relatively few minimal encouragers and other strategies designed to keep the child talking. The caregivers used a high proportion of direct, leading and coercive strategies to elicit information from their children. Even when caregivers used open‐ended questions, their children provided less event‐related information than they did to the police interviewers. Conclusion. The quality of evidence obtained from children with intellectual disabilities is likely to be dependent (albeit in part) on the degree to which police interviewers adhere to best‐practice guidelines, as well as the children's general experience with an open‐ended style of communication.     

Using Spaced Learning Principles to Translate Knowledge into Behavior: Evidence from Investigative Interviews of Alleged Child Abuse Victims

The present study assessed the progress of 13 investigative interviewers (child protection workers and police officers) before, during, and after an intensive training program (n = 132 interviews). Training began with a 2-day workshop covering the principles of child development and child-friendly interviewing. Interviewers then submitted interviews on a bi-weekly basis to which they received written and verbal feedback over an 8-month period. A refresher session took place two months into training. Interestingly, improvements were observed only after the refresher session. Interviews conducted post-refresher training contained proportionally more open-ended questions, more child details in response to open-ended questions, and proportionally fewer closed questions than interviews conducted prior to training and in the first half of the training program. The need for ‘spaced learning’ may underlie why so many training programs have had little effect on practice.     

Can You Build a Better Cop?

Research Summary

By drawing from psychology and economics, we present an experimental evaluation of a procedural justice training program designed to “slow down” police officers’ thought processes during citizen encounters. We find that officers who were randomly assigned to participate in training were as engaged in the community as similarly situated officers, but they were less likely to resolve incidents with an arrest or to be involved in incidents where force was used. These changes were most evident among officers who worked in areas with a modest level of risk.

Policy Implications

Police officers who are actively engaged with the public can reduce crime through general deterrence and by arresting criminals. Nevertheless, excessive discretionary arrests and the use of force by officers can reduce public trust in the police. To date, there is scant evidence as to how police departments can successfully train officers to balance enforcement and public trust in the field. Through our study, we demonstrate that a relatively minor supervisory intervention may cause substantive changes in how police and citizens interact with each other.     

Training in the Strategic Use of Evidence technique: Improving deception detection accuracy of American law enforcement officers

The Strategic Use of Evidence (SUE) approach is a framework for planning and executing suspect interviews with the aim of facilitating judgments of truth and deception. US law enforcement officers (N = 59) either received training in the SUE approach or did not. Each officer interviewed a mock suspect (N = 59) who had either committed a simulated security breach or had completed a benign task. The officers who received SUE training interviewed in line with the training: They questioned the suspect systematically, withheld the evidence and critical case information until after questioning, and relied on statement-evidence inconsistency to detect deceit. Consequently, SUE-trained interviewers achieved a higher deception detection accuracy rate (65%) compared to untrained interviewers (43%).     

The relationship between job status,interviewing experience,gender, and police officers' adherence to open‐ended questions

Purpose. The current study examined whether several factors related to the job and demographic profile of police officers are associated with adherence to best‐practice guidelines when interviewing children. Method. One hundred and seventy‐eight police officers completed a standardized (simulated) interview regarding an allegation of abuse by a 5‐year‐old child. Immediately prior to this interview, details were obtained from the officers' regarding their job status, gender, interview experience, the timing and nature of prior training/supervision, and experience outside the policing profession with young children. Results. The results showed that timing of training was the only factor that related to interview performance. The proportion of open‐ended questions among participants who completed their interviewer training course less than 1 month prior to the simulated interview was better than those who completed the training earlier. Interestingly, the performance of the latter group was identical to that of a group of participants who had not yet received any formal interview training. The implications of the findings are discussed, along with directions for future research.     

Police officers' perceptions of older eyewitnesses

Purpose. This study examined United Kingdom police officers' perceptions about older witnesses (>60 years) and their thoughts about employing the cognitive interview (CI) with this group. Method. A questionnaire was used to assess officers' opinions about current interviewing protocols for older witnesses, including the CI, and to explore the challenges involved with interviewing older witnesses. Results. Over half of the officers surveyed perceived older witnesses to be less reliable and less thorough than younger witnesses. Many officers lacked confidence in dealing with the emotional distress and memory loss often displayed by older witnesses and victims. Several officers stated they were inadequately trained and had insufficient time to devote to interviewing in general. Moreover, the number of officers who considered the CI to be helpful with older witnesses was roughly equivalent to the number of officers who believed it was not. Conclusions. These results suggest that police officers, like mock jurors, consider older adult witnesses and victims to be less reliable and thorough than younger adult witnesses. Furthermore, the results indicate that many officers are not always satisfied with their interviews of older witnesses and victims. Implications for officer training are discussed.     

Understanding how police officers think about mental/emotional disturbance calls

Police officers frequently respond to calls involving persons with mental illnesses and in doing so, they are key gatekeepers of access to mental health treatment as well as entry into the criminal justice system. Programs such as Crisis Intervention Teams (CIT) are being implemented across the United States and elsewhere to train officers to respond more effectively and facilitate access to mental health services when appropriate. These programs would benefit from a thorough understanding of these encounters from the perspective of police officers. We take as a premise that officers develop frames of reference or “schema” for understanding and responding to these encounters that are shaped by socialization, training, and their experience as police officers. In this study, we examine police officer schema of mental/emotional disturbance (M/EDP) calls. Qualitative interviews provided the foundation to develop the Needs on the Street Interview (NOSI) to tap officer schema of four types of M/EDP scenarios. The NOSI was administered to 147 officers in Chicago and Philadelphia. Latent Class Analysis (LCA) was conducted separately for each scenario to examine groups of officers with different schema as well as predictors of schema group. For three of the four scenarios, officers were classified into a two category or schema model, for the fourth (crime reported) a three category model was supported. Schema groups tended to be differentiated by ratings of level of resistance/threat and substance use. Contrary to our expectations, CIT and law enforcement experience did not predict officer schema group. While the CIT model emphasizes de-escalation skills to reduce resistance and the need for officers to use force, CIT and other training programs may want to consider increasing content related to factors such as co-occurring substance use and managing resistance.     

The Psychological Impact on Police Officers of Being First Responders to Completed Suicides

When a suicide is completed, police officers are often among the first responders. Little attention has been paid to the emotional and psychological impact on the police officer in this specific situation. This study examines the effects encounters with completed suicides have on the emotional and psychological well-being of the police officer. This is a qualitative study, which intends to bring alive the feelings, thoughts, actions, choices, and challenges of police officers who have encountered completed suicides as imparted through participants' stories. Interviews were done with eight police officers. In addition, interviews were done with a coroner, a police chaplain, and a police psychologist to add some unique perspectives to the police officers’ experiences of encountering completed suicides. Interviews were done in a semi-structured, focused format involving an ongoing fine-tuning of questions. The overarching finding reveals the central role played by police culture in shaping how police officers come to perceive this experience, and how they subsequently choose to mediate it. This study identifies ten strategies police officers use to mediate this experience, and discusses the possible psychological consequences of employing each strategy.     

Police officers’ judgements of veracity,tenseness, cognitive load and attempted behavioural control in real-life police interviews

Abstract

The present experiment examined the apparently incongruent findings that police officers (i) believe that suspects show nervous behaviour when they lie but (ii) seem able to detect deceit in suspects who do not show nervous behaviours. It was hypothesized that police officers’ judgements about whether a suspect is lying would not be correlated with their judgements regarding whether the suspect is tense, but, instead, would be correlated with their judgements regarding whether suspects are having to think hard or attempting to control their behaviour.

Each of 84 police officers saw seven truths and seven lies told by suspects during their police interviews. Participants in Condition 1 were asked to indicate after each clip whether the suspect was lying, whereas participants in Condition 2 were asked to note after each clip to what extent the suspect appeared to be tense, having to think hard or attempting to control their behaviour. Condition 3 was a combination of Conditions 1 and 2 and participants were asked all the above questions. The findings support the hypotheses and therefore negate the assumption that police officers primarily look for cues of nervousness when they attempt to detect deceit.     

The commemoration of death,organizational memory,and police culture

Police scholars document that although there is fragmentation of the so‐called “monolithic” police culture, historically consistent features of the occupational culture of police exist. By drawing on ethnographic observations in three U.S. police departments, I describe how one consistent feature of police culture—the preoccupation with danger and potential death—is maintained by the commemoration of officers killed in the line of duty. Through the use of commemorative cultural artifacts, officers and departments construct an organizational memory that locally reflects and reifies the salience of danger and potential death in policing. Furthermore, commemoration of fallen officers is not restricted to a department's own; the dead of other departments are commemorated by distant police organizations and their officers, maintaining broad, occupational assumptions of dangerous and deadly police work that transcend a single department and its localized organizational memory. Implications for the study of police culture, inequalities in policing, and police reform are considered.     

To Internet or Not?: Assessing the Efficacy of Online Police Training

The field of police training is undergoing a paradigm shift due to technology, and this study used an andragogical lens to explore various considerations for the implementation of online education (OE) into police training regimens. This comprehensive assessment utilized quantitative and qualitative methods to examine the feasibility of OE for professional development among police officers in Tennessee. The study examined whether the potential performance of police officers in OE is related to various demographic factors and evaluated the perceptions of police regarding online education. Data analyses indicated a statistically significant relationship between potential online learning success and various factors, including formal educational level and previous exposure to OE. The majority of participants in the study said they preferred OE to traditional instruction, felt that OE is an appropriate delivery method for professional development, and believed that the use of OE for delivery of professional development provides increased training opportunities.     

Youth justice conferencing and police referrals: The gatekeeping role of police in Queensland, Australia

Youth justice conferencing in Queensland, Australia relies on the discretionary referral of young offenders by the police. The low rate of police referrals to conferencing is an ongoing concern for conference organizers. The research presented in this study explored Queensland police officers' training, experience, understandings of youth justice conferencing, and their individual discretionary policing style. The impact of these factors on officers' attitudes towards conferencing and their reported likelihood of referring to conference were examined. One hundred eighty-four Queensland police officers stationed in police regions where conferencing was available participated in the study. Of these officers, 15 percent had never heard of conferencing. Of officers who had heard of conferencing, 35 percent had received training, 21 percent had referred a young person to a conference, and 20 percent had attended a conference. Officers' understandings of conferencing were significantly related to their reported likelihood of referring a young person to a conference. The results indicated that to increase police referrals of young people to conferences, police need to be exposed (both through training and attendance) to the philosophy of and procedures involved in conferencing.     

Note on a Training Program for Brief Decision Making for Frontline Police Officers

Purpose

The present paper describes the theoretical basis for a brief decision-making training program for frontline police officers as well as an outline of the training program, officers’ evaluation of perceived relevance and perceived learning effects.

Design

A between group design was used in order to test for differences in evaluation between officers at different training levels.

Results

High scores were obtained on all four items related to the evaluation (>84% scored in the highest category). When separating the subjects into groups based on their previous training (regular police response personnel vs. SWAT-type personnel), regular police response personnel obtained higher scores on perceived learning. However, both groups showed high scores on perceived learning. Both groups scored high on their evaluation of perceived relevance of the training program and no difference was found between the two groups.

Practical implications

The brief decision making training program that expands ordinary tactical training was highly appreciated by police officers and was seen as complementary to ordinary training.

     

Trauma Resilience Training for Police: Psychophysiological and Performance Effects

The objective of this study is to test the effects of police trauma resilience training on stress and performance during a critical incident police work simulation. Rookie police officers (N = 18) participated in a randomized trial of a 10-week imagery and skills training program versus training as usual. Twelve months later, psychophysiological stress and police work performance were assessed during a live critical incident simulation. Training resulted in significantly less negative mood, less heart rate reactivity, a larger increase in antithrombin, and better police performance compared to controls. Trends for cortisol and self-reported stress also suggested benefits of training. This novel training program is a promising paradigm for improving police well-being, stress resiliency, and optimizing job performance.     

Forced confabulation more strongly influences event memory if suggestions are other‐generated than self‐generated

Purpose. Virtually all eyewitnesses to a crime, who eventually testify in court, are interviewed by police officers at least once. How do these interviews affect what the eyewitnesses are subsequently likely to report? The purpose of this study is to compare the relative impact of self‐ versus other‐generated misinformation on confabulated memory about an event. Self‐generated misinformation can occur by encouraging eyewitnesses to guess or speculate about possible answers to questions about which they report having no memory. Other‐generated misinformation can occur by having an investigator suggest an answer to an eyewitness. Methods. After viewing a 5 minutes crime video, participants answered written questions. One week later these same questions were answered again. We specifically focused on individuals' answers to unanswerable questions that probed information not actually presented in the video. If a participant answered an unanswerable question, we know that their answer was confabulated because the information was not presented in the video. Results. If an answer to an unanswerable question was forced confabulated at time 1, that answer was more likely to be repeated at time 2 if it had been other‐generated (suggested in the question) rather than self‐generated (fabricated by the participant). Conclusions. Pressuring eyewitnesses to answer questions about an event, when they indicate that they do not know the answer, can result in false confabulations. Answers suggested by the investigator are more likely to be repeated later than are answers that are simply self‐generated or speculated by the eyewitness. These results are consistent with the reality monitoring framework and ‘recollect‐to‐reject’ metacognitive reasoning strategies.
