Exam 4; Screening for Hearing Loss
questions with complete solutions
screening - correct answer ✔✔ is designed to expediently and reliably identify those likely to
have a disorder within the general population. More definitive follow-up testing is typically
required to confirm (or refute) the findings of the screening.
test sensitivity - correct answer ✔✔ tested positive for the disorder or trait
test specificity - correct answer ✔✔ tested negative for the disorder or trait
prevalence - correct answer ✔✔ the estimated proportion of the population who have a
particular disorder or trait
introduction - correct answer ✔✔ - For many adults, the development of hearing loss is often
readily apparent to the hearing-impaired individual, and assistance will most likely be sought
out.
- But some older adults with mild or moderate amounts of sloping, high-frequency,
sensorineural hearing loss wait as long as 10-15 years from their first suspicion of hearing
problems to their first appointment with an audiologist for a complete hearing evaluation.
purpose of screening - correct answer ✔✔ - designed to separate persons who are likely to have
an auditory disorder from those who are unlikely to have an auditory disorder and to do so in a
simple, safe, rapid, and cost-effective manner.
- are intended to be preventive measures that focus on early identification and subsequent
intervention.
what makes a good screening test? - correct answer ✔✔ acceptable
, reliable
safe and cost effective
long term costs
acceptable - correct answer ✔✔ easy to administer, readily interpretable and well received
reliable - correct answer ✔✔ consistent results that do not differ among the same individual.
test - retest should yield the same results
safe and cost effective - correct answer ✔✔ salary of individual administering, cost of
equipment and supplies, reimbursement rate, time required
long term costs - correct answer ✔✔ false positives then yield many normal diagnostic test
costs
sensitivity and specificity - correct answer ✔✔ validity of test has two components
sensitivity - correct answer ✔✔ the ability of a screening test to identify accurately an ear that is
abnormal (the proportion of people who have a disease who have positive result)
A/(A+C) = __________
specificity - correct answer ✔✔ the ability of a screening tool to identify normal ears
(proportion of people who don't have the disease who have a negative test)
D/(D+B) = __________
principles of evaluating a screening test - correct answer ✔✔ - the primary goal is to distinguish
within the population at large those individuals who exhibit an auditory disorder from those
who do not.
