17
Q

What are types of reliability tests?

A
  1. Test Retest
  2. Interrater
  3. Intrarater
  4. Internal Consistency
  5. Alternate Forms
  6. Split Half
18
Q

What is Test Retest?

A

used to establish that an instrument/tool is capable of measuring a variable consistently

19
Q

What is Inter rater Reliability?

A

Variations between 2 or more raters who measure the same group

20
Q

What is Intra Rater Reliability?

A

Scores should match when the sam examiner tests the same subjects on two or more occasions

21
Q

What is Alternate/Parallel Forms?

A

To see if 2 versions of the same instrument are equivalent

22
Q

What is Internal Consistency?

A

Often used to construct scales/Questionaires

23
Q

What is Split Half Reliability?

A

Takes all questions and divides them in halves

24
Q

What is the Modern Approach for Quantifying Reliability?

A
  1. Intra Correlation Coefficients

2. Kappa

25
Q

What are Intra Correlation Coefficients?

A

for continuous scales scores

26
Q

What are Kappa used for?

A

for categorical scale scores

27
Q

SEM?

A

The absolute measure of reliability

28
Q

Responsiveness

A

The ability of an instrument to detect minimal change over time

29
Q

What is MDC?

A

the ability of an instrument to detect change beyond measurement error

30
Q

What is MCIB?

A

the ability of an instrument to detect minimally important change

31
Q

What are types of measurement validity?

A
  1. Face Validity
  2. Content Validity
  3. Criterion Validity
  4. Concurrent Validity
  5. Predictive Validity
  6. Construct Validity
32
Q

What is Face Validity?

A

Indicates that the instrument is measuring what its suppose too; the lowest form of measurement validity

33
Q

What is Content Validity?

A

Indicates that the items that make up an instrument adequately sample the universe of content that defines the variable being measured. Most useful in questionnaires and inventories

34
Q

What is Criterion Validity?

A

Indicates that the outcomes of one instrument, the target test, can be used as substitute measure for an established reference standard criterion test “Gold Standard”

35
Q

What is Concurrent Validity?

A

Establishes validity when two measurements are taken relatively at the same time

36
Q

What is predictive Validity?

A

Establishes that the outcome of the target test can be predicted a future criterion score

37
Q

What is Construct Validity?

A

Establishes the ability of an instrument to measure an abstract construct and the degree to which the instrument reflects the theoretical components of the construct
