  1. why do we do screenings?
    • conducted on groups of people who might not know they have a hearing problem
    • people who are unable or reluctant to seek professional services
    • there is a significant probability of finding those with the disorder
    • the disorder is considered to be important enough to identify in the larger pop
  2. what makes an effective hearing/screening program
    • target subpops using efficient and cost-effective methods
    • identify people with potential hearing problems
    • have options for follow up measures
  3. what should hearing screenings involve
    • pas/fail measures
    • pass=those who most likely do not have a hearing loss
    • fail=those who may possibly have a hearing loss
  4. in order for screenings to be effective they must have good...
    • reliability-similar results each time
    • validity-identifies what is intended
  5. universal and targeted screenings
    • universal=applied to a relatively large pop
    • targeted=more cost effective approach, higher prevalence rate
  6. screening for high risk infants
    • targeted hearing screening
    •     -this focuses on a subpop
    • advocated since the early 1970s
