PSYC 4364 Lecture Notes - Lecture 10: Average White Band, Experiment, Natural Disaster
● Epidemiology = study of numbers
● Basic epidemiological approaches to disaster research: bromet and havenaar
○ What are various ways of collecting data?
■ Can’t get to site of trauma...mail surveys? Limit us b/c may have lower
response rate
■ What is best way to collect data after traumatic situation?
● Average white band: person to person (1977) clip on youtube
● PERSON TO PERSON/FACE TO FACE
○ Advantages: build rapport, see their emotional distress,
body language
■ Value of face-to-face procedures
● Advantages
○ Generalization
○ Comprehensive and in depth info ( can’t get that through
telephone/ surveys)
○ Biological assessments
○ Pick up on non-verbal cues (flashback)
○ Build rapport
● Bottom line: can do good methodological sound research even
under “suboptimal conditions”
○ Jones told story about being hit by african american client.
Assumed that the man would relate to him because of their
shared complexions but due to their different lifestyles, that
assumption was wrong.
○ Design options
■ Retrospective cohort designs
■ Case-control design
○ Retrospective data - collect data after event
○ Prospective data - collect data prior to traumatic event
■ Exp: mental health data, education history
■ If we maintain that following trauma, a % of individuals will do poorly after
event- we need data to help us figure out the real impact/change after the
trauma
■ Data that may predict how someone will do after trauma
■ ***be able to come up with a possible main affect hypothesis for a given
situation
○ “Natural Experiments” / true experiment (pre-post design)
■ Give exp of true experiment data: requires both retrospective and
prospective data!!!!!!!!
■ Incidence - 1st exposure/new cases
■ Prevalence - ongoing/overall cases
○ Chernobyl
Document Summary
Basic epidemiological approaches to disaster research: bromet and havenaar. Limit us b/c may have lower response rate. Average white band: person to person (1977) clip on youtube. Advantages: build rapport, see their emotional distress, body language. Comprehensive and in depth info ( can"t get that through telephone/ surveys) Bottom line: can do good methodological sound research even under suboptimal conditions . Jones told story about being hit by african american client. Assumed that the man would relate to him because of their shared complexions but due to their different lifestyles, that assumption was wrong. Retrospective data - collect data after event. Prospective data - collect data prior to traumatic event. If we maintain that following trauma, a % of individuals will do poorly after event- we need data to help us figure out the real impact/change after the trauma. Data that may predict how someone will do after trauma.
