Validity

Question 1

validity

Answer 1

the extent to which you are measuring what you actually want to measure

Question 2

Ways to assess validity

Answer 2

1. subjective assessment

2. empirical assessment

Question 3

subjective assessment

Answer 3

1. face validity

2. content validity

Question 4

face validity

Answer 4

the measure appears to accurately assess the intended variable
- face validity shifts around over time

Question 5

content validity

Answer 5

comparing the content of the measure with the theoretical definition of the construct

Question 6

empirical assessment

Answer 6

1. criterion
2. convergent
3. discriminant

Question 7

criterion validity

Answer 7

is the measure correlated with some concrete outcome it should be correlated with

Question 8

two types of criterion validity

Answer 8

1. predictive validity

2. concurrent validity

Question 9

predictive validity

Answer 9

using the measure to predict future outcomes

Question 10

concurrent validity

Answer 10

examines the relationship between the criterion behaviour and the measure at the same time

Question 11

known groups paradigm

Answer 11

take groups with a known orientation and you look to see if your measure predicts where they fall
- you know where the groups sit and you hope that your measure can distinguish that

Question 12

convergent validity

Answer 12

the extent to which scores on the target measure in question are related to scores on other measures of the same or similar constructs

Question 13

discriminant validity

Answer 13

the measure should discriminate between the construct being measured and other unrelated constructs

Question 14

measures must be both

Answer 14

reliable and valid

otherwise they are useless
