What is the term for the degree to which a measure reflects meaningful elements of a construct?

Content validity

(T/F) Goniometric measures have greater interrate reliability than intrarater reliability

False - Intrarater reliability is always greater

(T/F) A numerical pain sale has greater content validity than a pain disability questionnaire

False - less

What form of criterion related validity involves measurements that suggest the form of treatment a person should receive?

Prescriptive

If a measure is consistent on the same individual on separate occasions, it is demonstrating: internal validity construct validity inter-rater reliability test-retest reliability

test-retest reliability Test-retest reliability is a measure of reliability obtained by administering the same test on separate occasions over a period of time to the same individual.

What is the name for the type of validity in which an interpretation is justified by comparing a measurement to a "gold standard" measurement at approximately the same time? concurrent validity construct validity face validity prescriptive validity

concurrent validity An example of concurrent validity is as follows: Heart rate measurements made by palpation of peripheral pulses will have concurrent validity if the heart rate measurements by palpation are associated with the heart rates measured simultaneously from an electrocardiogram.

Evidence of ______________ validity is through logical argument based on theoretical and reach evidence

construct

Scorebuilders comprehensive practice exams demonstrate ____________ validity for the NPTE

predictive

What form of criterion related validity involves comparing a measure to a gold standard measurement?

Concurrent

Concurrent, predictive, and prescriptive validity are examples of ________ -________ validity

Criterion related

What is term for the extent to which items or elements that contribute to a measurement reflect one basic phenomenon or dimension?

Internal consistency

(T/F) Test retest reliability can be affected by fatgiue

True

(T/F) The NPTE has good alternate forms reliability

True

Which statement is true regarding the relationship between validity and reliability? a test that is reliable cannot be valid a valid test must be reliable a test may be valid, but not reliable reliability and validity are not related

a valid test must be reliable Reliability refers to the repeatability of findings. Validity refers to the credibility or believability of the research. If data are valid, they must be reliable. However, if a test is reliable, it is not necessarily valid.

The validity of a measure refers to the: accuracy with which it measures the construct comprehensiveness with which it measures the construct consistency of the measurement particular type of construct specification

accuracy with which it measures the construct Validity is the degree to which a useful or meaningful interpretation can be inferred from a measurement. Examples of different types of measurement validity include face, content, construct, and criterion-related.

Which type of validity is determined by providing evidence that a measuring instrument contains all relevant elements of a construct with no extraneous elements? construct validity content validity concurrent validity predictive validity

content validity Content validity is determined by providing evidence that a measuring instrument contains all relevant elements of a construct with no extraneous elements.

Which type of validity is established by a comparison to another measurement? construct validity content validity criterion-based validity predictive validity

criterion-based validity Criterion-based validity is established by a comparison to another measurement. This commonly occurs by comparison of the measurement to the gold standard measurement for the variable being tested.

The extent to which the results of an experiment can be generalized across populations, times, and settings refers to: internal validity external validity interrater reliability intrarater reliability

external validity External validity refers to the degree to which results of the research study are generalizable to populations or circumstances beyond those included in the study. Threats to external validity include the interaction of treatment with the specific type of subjects tested and the place (setting) and time (history) in which the experiment is performed.

What is the term for the degree to which a measurement appears to test what it is supposed to test?

face validity

This type of validity is a measure of the degree to which a measurement appears to test what it is supposed to? construct validity content validity face validity criterion validity

face validity Face validity refers to the degree to which a measurement appears to test what it is supposed to. It is a measure of the transparency or relevance of a test.

What is the term when two therapists measure drastically different values on the same patient? poor intrarater reliability poor interrater reliability poor internal validity poor external validity

poor interrater reliability Interrater reliability refers to the consistency or equivalence of measurements made by more than one person. Interrater reliability indicates the agreement of measurements taken by different examiners.

What is the prerequisite for validity?

reliability

A simple definition of reliability would be: the reproducibility of an instrument the validity of an instrument the success of an instrument the complexity of an instrument

the reproducibility of an instrument Reliability is the degree to which an assessment tool produces stable and consistent results.
