research methods and police psychology Flashcards
what are the two types of independent variables in forensic psychology research?
- estimator variables (present at the time of crime and cannot be changed)
- system variables (may be manipulated to increase the effectiveness of procedures)
what are the most common research designs in forensic psychology?
correlational and experimental
when is the use of deception acceptable in research?
- when it poses a minimum risk to participants
- when there is a post-experiment debriefing
- when sharing the real purpose of the experiment will invalidate the results
name some of the clinical assessments used in research
- self-report
- interviews
- standardized tests
- projective tests
- behavioral observation
- psychophysiological tests
what elements are unique to police culture/law enforcement?
- hostile and often dangerous work environment
- legitimate power to create, display, and maintain authority over the public
- values control, authority, solidarity, and isolation
what are the 4 categories of common tasks performed by police psychologists?
- assessment
- intervention

- consulting and research
explain screening out procedures in police selection
- try to eliminate the candidates who demonstrate psychopathology and emotional instability, or cannot perform the job in a safe manner
- usually when you don’t have a lot of applicants to begin with
explain the screening-in procedures in police selection
- identify those attributes that distinguish one candidate as being potentially more effective than another
- used when there are many candidates
what are the two main stages of the development of police selection instruments?
- the job analysis stage
- the construction and validation stage
explain the job analysis stage of the dev of police selection instruments
- identifying KSAs (knowledge, skills, and abilities) that make a good police officer
what are common problems with KSAs
- need to update frequently bc valuable skills needed will change over time
- no consensus on what the core KSAs should be
what is the validation measure that is the most important for police selection instruments?
predictive validity (is there a relationship between scores obtained from selection instruments and measures of actual job performance)
what are some of the instruments used in the construction and validation stage?
- selection interview
- psychological tests
- assessment centres
what are the types of psychological tests used in police selection?
- cognitive ability tests
- personality tests (MMPI-2 and Inwald Personality Inventory)
what is the use of an assessment centre in police selection?
- simulations of real-life policing tasks to observe the behaviour of the applicants
