Deck 11: Critically Appraising and Selecting Assessment Instruments

Question 1

For an instrument to be reliable:

A) it must be valid.
B) an individual's responses to it must be consistent.
C) it must be sensitive.
D) All of the above.

Answer 1

B

Question 2

Internal consistency reliability requires:

A) internal validity.
B) stability in responses over time.
C) positive correlations among the items of an instrument.
D) All of the above.

Answer 2

C

Question 3

Coefficient alpha refers to:

A) the statistical significance of an instrument.
B) the stability of an instrument.
C) interrater reliability.
D) the mean of all those split-half correlations of scale items.

Answer 3

D

Question 4

Test-retest reliability:

A) is more expedient and less costly to assess than internal consistency reliability.
B) involves testing people with the same instrument at least 6 months between test and retest.
C) is affected by the possibility that some people might really change between test and retest.
D) All of the above.

Question 5

Validity:

A) requires reliability.
B) refers to whether an instrument really measures what it is intended to measure.
C) Both a and b.
D) None of the above.

Question 6

Face validity:

A) is the strongest form of validity.
B) is the weakest form of validity.
C) is a form of criterion validity.
D) None of the above.

Question 7

Criterion validity:

A) can be in the form of predictive validity.
B) can be in the form of concurrent validity.
C) can be in the form of known-groups validity.
D) All of the above.

Question 8

Construct validity:

A) involves assessing convergent validity.
B) involves ruling out alternative constructs via assessing discriminant validity
C) might involve assessing factorial validity
D) All of the above.

Question 9

If an instrument has linguistic equivalence across two different cultures, it will:

A) have conceptual equivalence.
B) have metric equivalence.
C) be reliable and valid in both cultures.
D) All of the above.
E) None of the above

Question 10

If an instrument is reliable, then it is also valid.

Question 11

An instrument is reliable if responses to it are consistent.

Question 12

To have internal consistency reliability, an instrument's coefficient alpha should be less than .05.

Question 13

Test-retest reliability is particularly relevant if an instrument is to be used to monitor treatment progress.

Question 14

Interrater reliability requires that each rater give exactly the same rating to each observed behavior.

Question 15

Face validity requires no evidence that an instrument is really valid; it just means that in somebody's judgment the items seem to tap the concept in question.

Question 16

To have content validity, a group of experts must agree that the items on an instrument adequately cover the full domain of the concept that the instrument intends to measure

Question 17

Because some instruments might measure a related construct more accurately than the intended construct, some instruments can have criterion validity without having construct validity.

Question 18

One question to ask when choosing an assessment instrument is whether the instrument is sensitive to relatively small, but important changes.

Question 19

A good translation of an instrument into another language assures conceptual equivalence.

Question 20

The length and complexity of an instrument may make it infeasible to use even with adult clients who read well and are not too impaired to complete it.

Question 21

It's better to use an instrument with excellent validity results derived from a sample of people unlike the ones in your practice than to use an instrument with only adequate validity results derived from a sample of people very much like the ones in your practice.

Question 22

Define measurement reliability and describe three main approaches for measuring it.

Question 23

Define measurement validity and describe its various forms.

Question 24

Define measurement sensitivity and explain its importance in EBP.

Question 25

Discuss the importance of cultural sensitivity in measurement, and describe three forms of cross-cultural measurement equivalence.

Question 26

Discuss the factors to ponder when considering the feasibility of a measurement instrument.

Question 27

Discuss the importance of sample characteristics when considering the applicability of a measurement instrument to a specific EBP situation.
