lecture 4

Question 1

face validity

Answer 1

• extent to which measurement method appears on its face to measure the construct of interest
• largely subjective
• usually assessed informally - part of pilot study
  10 item sub scale of conscientiousness - Goldberg, 1992
• get upset easily - not face valid for this sub scale as it measures emotional stability

Question 2

content validity

Answer 2

extent to which a measure ‘covers’ the construct of interest
assessed by carefully checking the measurement method against the conceptual definition of the construct

Question 3

criterion validity

Answer 3

extent to which peoples scores on a measure are correlated with other variables that one would expect them to be correlated with construct being measured
e.g. expect test anxiety scores to positively correlated with general anxiety and blood pressure during examination period

Question 4

concurrent validity

Answer 4

when construction and criterion validity are measured at the same time
- how well doest test correlate with other established test at around the same time

Question 5

predictive validity

Answer 5

• when criterion is measured at some point in the future

- how well does the test credit something in the future such as job performance or degree grade

Question 6

discriminant validity

Answer 6

extent to which scores on a measure are not correlated with measures of variables that are conceptually distinct
- a new scale should not correlate with other scales designed to measure a different construct
