“…Maladaptive stress responses during a critical incident put the officer and members of the public at risk of injury or death. Furthermore, maladaptive stress responses can negatively affect an officer's health and performance over time (Covey, Shucard, Violanti, Lee, & Shucard, 2013; 638708S GOXXX10.1177/2158244016638708SAGE OpenAndersen and Gustafsberg…”

A Training Method to Improve Police Use of Force Decision Making

Police safety and use of force decisions during critical incidents are an ongoing source of concern for both police practitioners and the public. Prior research in the area of police performance reveals that psychological and physiological stress responses during critical incidents can shape the outcome of the incident, either positively or negatively. The goal of this study was to test a training method to improve use of force decision making among police. This randomized controlled pilot study consisted of training officers to apply techniques to enhance psychological and physiological control during stressful critical incidents. Of a pool of 80 police officers, potential participants were invited based on equivalent age, years of experience, physiological characteristics (i.e., body mass index [BMI] and cardiovascular reactivity), and expertise. Results revealed that the intervention group displayed significantly better physiological control, situational awareness, and overall performance, and made a greater number of correct use of force decisions than officers in the control group (all ps < .01). The relevant improvements in use of force decision-making found in this pilot study indicate that this training method warrants further investigation. Improved use of force decision making directly translates into potential lifesaving decisions for police and the civilians they are working with.

“…Police officers may be at increased risk for decreased HRV due to their constant exposure to several occupational stressors (Covey et al, 2013; Fekedulegn et al, 2012; Miller, 2006; Violanti, 2011). In a recently published article on this cohort of police officers, both male and female officers reported experiencing psychologically threatening events on a regular basis (approximately three or more events per day in the past month) with events involving organizational and administrative pressure occurring more often than other events (Hartley et al, 2011).…”

Objective Low heart rate variability (HRV) has been linked to cardiovascular disease. Our objective was to examine the cross-sectional association between insulin and HRV. Methods Insulin levels were measured in 355 nondiabetic officers from the BCOPS study, following a 12 h fast. HRV was performed according to methods published by the task force of the European Society of Cardiology and the North American Society of Pacing Electrophysiology for measurement and analysis of HRV. Mean values of high (HF) and low frequency (LF) HRV were compared across tertiles of insulin using ANOVA and ANCOVA; p-values were obtained from linear regression models. Results Higher mean levels of insulin were significantly associated with lower (i.e., worse) mean levels of HRV before and after risk-factor adjustment. The results for HF HRV (ms2) were as follows: 1st insulin (µU/ml) tertile (156.3; 95% confidence interval (CI) = 128.6–189.9); 2nd tertile (154.3; 95% CI = 124.3–191.5); 3rd tertile (127.9; 95% CI = 105.0–155.8), p for trend = 0.017. Results with LF HRV were similar to HF HRV. Insulin was also inversely and significantly associated with HRV among officers with BMI ≥25 kg/m2, with ≥25.5% body fat, and among those who reported low (

“…Using a task that was similar to that of the above study (a visual Go/NoGo task with an A-X paradigm), Covey et al (2013) It is interesting to note that even works that failed to find correlation between overall PTSS and LPP reported negative correlations using cluster symptoms separately. Whereas a study that applied a face-matching paradigm to male combat veterans found a negative association between the LPP response to fearful faces and re-experiencing cluster symptoms (MacNamara et al, 2013), Wessa et al (2005) found a negative correlation between the LPP response to trauma-related images and avoidance/numbing cluster symptoms.…”

“…In emotion paradigms, slow wave activity indicates elevated positivity in response to highly arousing stimuli (Cuthbert et al, 2000;Mocaiber et al, 2010Mocaiber et al, , 2009). In fact, using distinct tasks, three studies found positive correlations between these variables: increased severity of PTSS was related to greater P3-family ERP amplitudes (Covey et al, 2013;Lobo et al, 2014;Veltmeyer et al, 2009). This evidence is consistent with a study that found that compared with healthy control subjects, traumatized groups (with and without PTSD) exhibited increased P300 and late positive complex amplitudes in response to trauma-specific questions (Wessa et al, 2006).…”
