Week 3/Chapter 4 Comprehensive Study Guide on Police Selection, Assessment, Stress, and Reform

History and Evolution of Police Selection Assessment

• The earliest form of formal assessment in police selection occurred in $1917$.
• Researcher Lewis Turban conducted a study revealing that the average IQ of police officers was $84$.
• Based on these findings, Lewis Turban recommended that police departments decline to hire any applicant with an IQ below $80$.
• Modern IQ evaluations are normed so that $100$ represents the average IQ across the general population; however, neither standardized norming nor modern intelligence tests existed in $1917$, meaning an IQ score of $84$ actually reflected average intelligence at that time.
• Subsequent recommendations for police assessment did not re-emerge until the $1960$s and $1970$s.
• During the $1960$s and $1970$s, widespread police corruption prompted public demands for reform, leading to recommendations for formal screening measures to eliminate problematic candidates prior to hire.
• Formal psychological assessment did not become routine practice in police departments until the $1990$s.
• The institutionalization of screening in the $1990$s was driven by high-profile, highly publicized incidents of police brutality, including the Rodney King case and the Abner Louima case.
• Contemporary selection efforts continue to evolve in response to ongoing public calls for systemic law enforcement reform.

Purpose and Traits of Police Selection

• Police selection is designed to evaluate job applicants to identify individuals who are most psychologically fit for police work.
• The vast majority of selection protocols operate primarily as a "screening out" mechanism to eliminate psychologically disturbed candidates, rather than identifying ideal candidates.
• Police departments identify several core traits required of an ideal officer:
  • Incorruptible: Possessing high moral character, making the candidate unlikely to accept bribes, frame suspects, or engage in unethical conduct.
  • Well adjusted: Possessing a "thick skin" capable of carrying out high-stress duties without experiencing severe psychological distress.
  • Sensitive / Thin skinned: Remaining sensitive to community needs and demonstrating empathy when responding to citizens in distress.
  • People-oriented: Demonstrating genuine interest in and compassion for human beings, acknowledging that a primary component of policing is helping people in distress.
  • Low impulsivity and aggression: Moderating emotional expression appropriately on the job without requiring complete emotional suppression.
  • Dedicated: Maintaining a strong commitment to the policing profession.
  • Obedient: Exhibiting willingness to follow orders without complaint or rebellion.
  • Logical: Making objective decisions based on available evidence rather than emotional or irrational beliefs.

Primary Selection Assessment Methods

• Police evaluation protocols rely on three primary methods: interviews, situational tests, and psychological testing.

Interviews

• The interview is the most widely utilized assessment tool in police selection, despite empirical evidence showing it possesses the poorest predictive validity.
• Drawbacks of the interview format include:
  • High distortion: Applicants routinely conceal negative behaviors or exaggerate positive traits to present themselves favorably.
  • Low reliability: Standard interviews lack consistency across sessions and interviewers; different interviewers elicit different information, and rapport between an interviewer and candidate can cause discussions to stray off-topic.
  • Low validity: Standard interviews fail to reliably predict whether an applicant will demonstrate strong job performance.
• Structured interviews utilize a standardized set of identical questions administered to every candidate, which increases reliability but fails to resolve issues of distortion and low validity.

Situational Tests

• Situational tests place candidates in realistic simulated scenarios to directly observe their behaviors, decision-making, and stress responses in morally ambiguous or challenging situations.
• These tests are largely out of favor for pre-employment screening because they are highly time-consuming and expensive, requiring small group sizes (a maximum of $5$ candidates at a time), specialized trainers, and actors.
• Scaled-down situational exercises remain in limited use prior to hire, including:
  • Patrol observation followed by hypothetical decision-making questions.
  • Case analysis and clue evaluation exercises.
  • Standardized police report writing tasks.

Psychological Testing

• Psychological testing offers high standardization, objective numerical scoring with minimal human bias, high test-retest reliability, and extreme cost-efficiency (e.g., a single test administrator can oversee $50$ candidates simultaneously).
• Intelligence and Cognitive Ability Tests:
  • Measures general intelligence or cognitive skills through tasks such as logic problems.
  • Police applicants generally score average to above average on cognitive assessments.
  • Cognitive test performance correlates directly with performance in police academy training due to the academic, exam-heavy nature of academy instruction.
  • Cognitive test performance does not correlate with actual on-the-job police performance, which depends primarily on behavioral decision-making in high-stress situations.
• Personality and Behavioral Tests:
  • Minnesota Multiphasic Personality Inventory (MMPI): A assessment comprising over $300$ questions measuring anxiety, obsessiveness, depression, anger, cynicism, conduct problems, and health concerns.
  • in wall personality inventory (also referenced as Inwald or IMWOLD): Developed specifically for law enforcement screening to measure behaviors directly relevant to policing, including lack of assertiveness, trouble with law and society, undue suspiciousness, and driving violations; demonstrates superior predictive ability for identifying poor job performance compared to traditional assessments like the MMPI.
  • National Police Officer Selection Test (POST): Evaluates practical cognitive skills including arithmetic, reading comprehension, and report writing.

Predictive Validity and Challenges in Screening

• Predictive validity evaluates the relationship between screening test scores and actual subsequent job performance.
• Assessing predictive validity in law enforcement is rare due to the high financial costs, long timeframes, and necessity of hiring independent evaluators.
• Methodological challenges in determining screening validity include:
  • Restriction of range: Screened-out applicants are never hired, leaving evaluators with no baseline performance data to verify whether rejected candidates would have actually performed poorly.
  • Social desirability distortion: Applicants manipulate application details and interview responses to project ideal traits (e.g., self-titling as a "grill technician" when operating a basic sandwich press).
  • Unpredictable rare events and false positives: Extreme job demands—such as shootouts or hostage negotiations—occur once or twice in a career for most officers. Screening designed to filter out individuals unable to handle rare extreme emergencies generates false positives, potentially excluding candidates who would excel at everyday policing duties.

Post-Hire Evaluation: Fitness for Duty

• Fitness for duty evaluations are ordered after an officer is hired, typically following a life-threatening incident, a firearm discharge, or observable manifestations of psychological distress.
• These evaluations must balance public safety concerns against employment laws prohibiting discrimination against individuals with mental illnesses (such as the Americans with Disabilities Act) and laws protecting medical privacy.
• Evaluation and Treatment Models:
  • Single Psychologist Model: One psychologist conducts the fitness for duty evaluation and subsequently delivers clinical treatment. This creates severe ethical conflict; while the psychologist can share evaluation details with command staff, APA ethical standards prohibit sharing ongoing treatment details without a credible threat of violence. Supervisors often develop improper expectations of ongoing disclosures.
  • Two Psychologist Model: The preferred model endorsed by the American Psychological Association (APA). One psychologist performs the evaluation and reports findings to department leadership, while an entirely separate psychologist delivers clinical treatment, fully protecting therapist-client confidentiality.

Police Academy Training and Criticisms

• Police academy training typically lasts between $14$ and $24$ weeks.
• Recruits attend the academy full-time ($40$ hours per week) as paid employees, receiving a reduced wage relative to active-duty pay.
• Academy curricula involve physical training, situational scenarios, classroom lectures, and written examinations.
• Criticisms of police academy training include:
  • High pass rates: Despite rigorous initial selection screening, nearly all recruits pass the academy. Approximately $25BA$ ($25BA$ or one-quarter) of officers leave the job within their first $16$ months of employment, suggesting academy standards may be too lenient to filter out candidates unsuited for actual field conditions.
  • Insufficient field training: Critics highlight a lack of practical field training and an absence of close, continuous supervision during initial field placements to catch and correct behavioral issues early.

Police Response to Mental Health Crises

• Historical deinstitutionalization significantly increased the role of law enforcement in responding to individuals experiencing mental illness.
• Research explicitly demonstrates that individuals with mental illness are not inherently more violent or dangerous than the general population.
• Quantitative indicators of police involvement in mental health:
  • $7BA$ of all police encounters involve individuals with mental illness.
  • Police officers complete $33BA$ (one-third) of all emergency mental health hospital detentions and referrals.
  • $90BA$ of police officers have responded to calls involving mental health crises.
  • $33BA$ of all annual police calls for service involve mental health-related situations.
• Interactions often occur in a legal "gray zone" involving non-criminal public disturbances or domestic requests for assistance (e.g., family members requesting help with medication compliance), requiring no formal legal or criminal intervention.

Empirical Studies on Police Interactions and Mental Illness

• Teflon (Teplin) Observational Study:
  • Conducted over a $14$-month period using trained graduate student observers tracking police interactions across two precincts in a large United States city.
  • Examined $884$ non-traffic encounters involving $1798$ citizens and $506$ arrest suspects.
  • Arrests occurred in $12.4BA$ of all observed stops and $29.2BA$ of encounters with identified suspects.
  • Observable signs of mental illness were present in $5.9BA$ of citizens encountered.
  • Disparate impact analysis revealed that $47BA$ of individuals displaying mental illness were arrested—nearly $20BA$ higher than the expected baseline arrest rate ($29.2BA$)—demonstrating that mental illness significantly increases arrest likelihood.
• Rossler and Terrell Study:
  • Evaluated $2178$ officers and $4500$ apprehended individuals across police departments in Portland, Colorado Springs, and Saint Petersburg, Florida.
  • Identified that $12.5BA$ of captured individuals had a mental illness, and $88.5BA$ of these individuals were unarmed.
  • Found no difference in the overall frequency of use of force between individuals with and without mental illness.
  • Identified a significant difference in force severity: $33BA$ (one-third) of individuals with mental illness suffered physical injuries from police use of force, compared to $25BA$ (one-quarter) of individuals without mental illness, controlling for suspect violence and weapons.

Crisis Intervention Teams (CIT) and Incarceration

• Specialized Crisis Intervention Training (CIT), based on the Memphis model, provides officers with comprehensive, ongoing instruction in recognizing mental illness, utilizing community mental health resources, de-escalating crises, and diverting individuals into health care rather than the justice system.
• CIT-trained officers exhibit lower rates of violence during encounters with mentally ill individuals, lower overall arrest rates, higher rates of resource linkage, and higher self-reported preparedness.
• Mental health prevalence in correctional facilities:
  • $56BA$ of state prisoners, $45BA$ of federal inmates, and $64BA$ of jail inmates report mental health problems (symptom expression).
  • Diagnosed mental disorders are present in $13BA$ to $20BA$ of incarcerated populations.
  • Research indicates that high symptom rates in prisons stem from the traumatic, crowded, and coercive environment of correctional facilities rather than pre-existing violent criminality.

Duties, Job Stress, and Burnout

• Police officer duties fall into three functional classifications:
  • Enforcing the law (arresting suspects, investigating complaints, preventing crime): Accounts for only $10BA$ of total daily job activity. (Zero-tolerance policies in the $1990$s required mandatory arrests for all infractions, substantially increasing enforcement activities while escalating citizen complaints and lawsuits).
  • Maintaining order (intervening in family disputes, managing traffic, addressing noise complaints): Accounts for $30BA$ of job activity.
  • Providing services (assisting in medical/psychological emergencies, helping stranded motorists, escorting funeral processions): Represents the largest overall proportion of police work.
• Stressors in policing belong to three core categories:
  • Physical and psychological threats: Dealing with dangerous confrontations, physical attacks, and hostile individuals.
  • Evaluation systems: Facing public criticism, hostile media coverage, court inefficiency, and systemic reliance on plea bargains.
  • Organizational and bureaucratic problems: Navigating complex hierarchies, filtered communication, inadequate leadership, ambiguous job directives, and unsupportive supervision.
• Burnout Components:
  • Emotional Exhaustion: Interpersonal drain from constant contact with distressed citizens; serves as the primary predictor of domestic strain, leading to higher rates of spousal conflict, anxiety, substance abuse, and divorce.
  • Depersonalization: Development of callous, unfeeling, and cynical attitudes toward crime victims, treating victims without empathy or concern.
  • Reduced Personal Accomplishment: Chronic feelings of professional incompetence and belief that one's efforts on the job are entirely ineffective.

Health Problems and Officer Suicide

• Police officers report elevated rates of anxiety, alcohol abuse, and health vulnerabilities within their first $5$ years of employment.
• Officers experience significantly higher rates of physical health conditions compared to the general public, including cancer, heart disease, hypertension, acute migraines, reproductive complications, chronic back pain, foot problems, and insomnia.
• Approximately $1BA$ of active police officers report having contemplated suicide.
• Badge of Life Study ($2016$ Data):
  • Recorded $124$ total officer duty fatalities in $2016$, of which $108$ ($87BA$) were suicides, establishing suicide as the leading cause of death among police officers.
  • Demographics of officer suicides: Average age of $42$ years with an average of $16$ years of service.
  • Prior to suicide, $83BA$ reported acute personal problems; $15BA$ to $18BA$ suffered from documented Post-Traumatic Stress Disorder (PTSD).
• Blue Health Organization Data ($2019$):
  • Documented over $200$ officer suicides in 2019$.\n- Internal stigma, fear of peer ridicule, and mandatory reassignment to administrative desk duty deter officers from seeking mental health treatment.\n- Stress Mitigation Strategies:\n - Emotional exhaustion: Implementing department exercise programs, counseling, and peer support systems pairing officers based on personality compatibility.\n - Depersonalization: Monitoring workplace conditions, rewarding positive community behavior, and funding continuing education like CIT.\n - Personal accomplishment: Clarifying promotion criteria, establishing clear policy feedback mechanisms, and implementing team policing (allocating half of an officer's shift to self-directed, proactive community work).\n\n# Police-Community Relations, Fatal Force, and Racial Bias\n\n- Officers experience public scrutiny ("life in a fishbowl"), civilian video recording, court reviews, and strict Fourth Amendment limits regarding unreasonable searches and seizures.\n- Rising public criticism over the past 40$years focuses on operational tactics (stops, arrests, interrogations) and police brutality (e.g., the$2011$UC Davis pepper-spray incident against peaceful protesters; the Black Lives Matter movement founded in$2013 following the acquittal of George Zimmerman in the death of Trayvon Martin).\n- The "thin blue line" symbol represents internal police solidarity, symbolizing the concept of law enforcement standing between societal order and chaos.\n\n## Fatal Use of Force Statistics\n\n- Washington Post Fatal Force Database (2019 Data):\n - Recorded 999$fatal police shootings in the United States in$2019$.
  • Racial composition of victims: $40.3BA$ White, $25BA$ Black, $16.3BA$ Hispanic, and $18.3BA$ Other/Unknown.
  • General United States population baseline: $60BA$ Non-Hispanic White, $13.4BA$ Black.
  • Disparate impact analysis reveals Black individuals are killed by police at nearly double their proportion in the general population ($25BA$ vs $13.4BA$).
• Prosecutorial Outcomes for Officers ($2005$–$2019$ Data):
  • Approximately $1000$ fatal police shootings occur annually (~$5000$ total deaths from $2015$ to $2019$).
  • Only $104$ officers were arrested or charged with murder or manslaughter for on-duty killings between $2005$ and 2019$.\n - Among 80$closed cases,$35$($41BA$) were convicted or pled guilty; only$4 officers were convicted of murder, with the remainder convicted of lesser charges such as manslaughter or reckless discharge of a firearm.\n - Only 33$of the$104$total charged cases involved armed victims; only$10BA of cases resulting in conviction involved an armed victim.\n\n## Psychological Research on Shooting Decisions\n\n- Split-second shoot/don't shoot laboratory simulations demonstrate that police officers are faster to shoot, and shoot more frequently, when encountering Black targets compared to White targets.\n- Disparities are driven by implicit bias, explicit prejudice, high situational anxiety/stress, cultural influences, and regional weapon prevalence (lax state gun laws increase shoot rates).\n- Extensive de-escalation training focused on tactical delay and situational assessment effectively reduces split-second decision disparities.\n\n# Police Reform and Community Policing\n\n- Community policing adopts a proactive orientation focused on crime prevention and community partnerships rather than reactive enforcement.\n- Chicago Police Department Model (6 Core Components):\n 1. Neighborhood orientation: Working directly with community members to address local safety concerns.\n 2. Geographic responsibility: Requiring officers to step out of patrol vehicles and walk beats to build personal relationships.\n 3. Structured responses: Deploying specialized teams for specific call types (e.g., CIT, juvenile officers, social work co-responders).\n 4. Problem-oriented focus: Preventing crime through structured community development (e.g., youth after-school programs).\n 5. Collaborative crime analysis: Assisting residents in evaluating local crime data to allocate resources effectively.\n 6. Specialized deployment strategies.\n- Approximately 58BA of police departments maintain full-time community policing officers.\n- Benefits: Improved public attitudes toward police, reduced citizen complaints, decreased fear of crime, and higher community attachment.\n- Disadvantages: Risk of crime displacement to adjacent non-community policing areas, potential corruption, and officer resistance to operational change.\n- Chicago defunded its community policing infrastructure in the early 2000$s, causing$10$years of progress to collapse in less than$1 year.\n\n# Task Force on 21st Century Policing\n\n- Established in 2014$$ by President Obama following the death of Michael Brown in Ferguson, Missouri.
• Core recommendations across six primary pillars:
  • Building Trust and Legitimacy: Implementing procedural justice frameworks to ensure stops, arrests, and investigations are transparent, fair, and accompanied by meaningful disciplinary sanctions for officer misconduct.
  • Policy and Oversight: Mandating strict use-of-force limits, de-escalation guidelines, and community oversight representation during force investigations.
  • Technology and Social Media: Partnering with the Department of Justice to deploy body cameras and communication technology responsibly.
  • Community Policing and Crime Reduction: Reorienting operational frameworks from reactive crime fighting toward proactive community policing.
  • Officer Wellness and Safety: Implementing mandatory tactical first aid training, seatbelt protocols, safe driving requirements, regulated shift lengths, exercise programs, stress management, and non-stigmatized mental health support.
