PTSD and Its Implications for Peace Officer Selection: Neurobiological Effects, Cognitive Impairment, Use-of-Force Decision-Making, and Current Assessment Implications

Course Description

This course examines the neurobiological and cognitive consequences of PTSD as they apply to psychological pre-employment evaluation of peace officer candidates. Drawing on peer-reviewed research in police psychology, cognitive neuroscience, and electrophysiology—including the University at Buffalo studies by Violanti and colleagues—participants will develop a comprehensive understanding of how trauma-related brain changes affect threat perception, response inhibition, and use-of-force decision-making. Assessment implications for current PEPE practice, including MMPI-3 applications, are addressed throughout.

Program Goals

Building upon doctoral-level training in psychological assessment, psychopathology, and neuropsychology, this program extends competency into the specialized domain of public safety pre-employment evaluation by integrating current peer-reviewed evidence on PTSD's neurobiological and cognitive sequelae with applied assessment practice. Participants will expand their capacity to conduct dimensionally comprehensive evaluations of trauma-exposed candidates that move beyond affective symptom screening to address the executive function, attentional, and inhibitory control deficits most directly linked to peace officer performance and public safety outcomes.

Learning Objectives

After completing this course, participants will be able to:

1. Identify the neurobiological mechanisms by which PTSD alters amygdala, prefrontal cortex, and hippocampal functioning and explain how these changes increase risk for use-of-force errors in peace officers
2. Describe the cognitive deficits associated with PTSD — including impairments in response inhibition, working memory, and attentional control — as documented in peer-reviewed research with law enforcement samples
3. Differentiate between PTSD as an emotional regulation concern and PTSD as a cognitive impairment concern within the framework of peace officer pre-employment psychological evaluation
4. Apply findings from the University at Buffalo neurophysiological research program, including event-related potential evidence from law enforcement samples, to inform interview strategy and data integration in pre-employment evaluations of trauma-exposed candidates
5. Analyze the pathway from PTSD-related neurobiological changes to elevated rates of excessive force allegations, identifying the specific cognitive capacities — including bias suppression, impulse control, and perspective-taking — that are impaired by chronic trauma exposure

PhD

Current Position & Expertise in Program Content:

John M. Violanti, Ph.D. - is a Full Research Professor in the Department of Epidemiology and Environmental Health, School of Public Health and Health Professions, University at Buffalo, NY. He is a police veteran, serving with the New York State Police for 23 years as a trooper, a member of the Bureau of Criminal Investigation, and as a founding coordinator for the Psychological Assistance Program for the State Police. Dr. Violanti has been involved in the design, implementation, and analysis of numerous suicide, stress and health studies over the past 25 years. He previously developed a five year study on stress and cardiovascular disease in police officers for the National Institute of Occupational Safety and Health and now continues a four year follow-up on that study. Dr. Violanti recently served as a committee member for the Institute of Medicine of the National Academies, Washington, DC, concerning strategies for developing a resilient workforce for the Department of Homeland Security. He also presented testimony at the President’s Task Force on 21st Century Policing on police wellness. He has authored over 150 peer-reviewed articles and 18 books on suicide, stress and PTSD and lectured nationally and internationally at academic institutions and police agencies on matters of suicide, stress, health, and trauma at work.
