What is factor analysis in construct validity?
A commonly used method (24-25) to investigate construct validity is confirmatory factor analysis (CFA). Like EFA, CFA is a tool that a researcher can use to attempt to reduce the overall number of observed variables into latent factors based on commonalities within the data.
Construct validity refers to how well a test or tool measures the construct that it was designed to measure. In other words, to what extent is the BDI measuring depression? There are two types of construct validity: convergent and discriminant validity.
- Statistical conclusion validity is the degree to which conclusions about the relationship among variables based on the data are correct or 'reasonable'.
- In psychometrics, criterion or concrete validity is the extent to which a measure is related to an outcome. Criterion validity is often divided into concurrent and predictive validity. In Standards for Educational & Psychological Tests, it states, "concurrent validity reflects only the status quo at a particular time."
- Internal consistency reliability is a measure of reliability used to evaluate the degree to which different test items that probe the same construct produce similar results.
Construct validity refers to the extent to which operationalizations of a construct (e.g., practical tests developed from a theory) measure a construct as defined by a theory. It subsumes all other types of validity. For example, the extent to which a test measures intelligence is a question of construct validity.
- Face validity is the extent to which a test is subjectively viewed as covering the concept it purports to measure. It refers to the transparency or relevance of a test as it appears to test participants. If an expert is asked instead, some people would argue that this does not measure face validity.
- Construct validity is "the degree to which a test measures what it claims, or purports, to be measuring." In the classical model of test validity, construct validity is one of three main types of validity evidence, alongside content validity and criterion validity.
- Population validity is a type of external validity which describes how well the sample used can be extrapolated to a population as a whole.
Content validity is an important research methodology term that refers to how well a test measures the behavior for which it is intended. For example, let's say your teacher gives you a psychology test on the psychological principles of sleep.
- Test reliability is measured with a test-retest correlation. Test-Retest Reliability (sometimes called retest reliability) measures test consistency — the reliability of a test measured over time. In other words, give the same test twice to the same people at different times to see if the scores are the same.

- Reliability is the degree to which an assessment tool produces stable and consistent results. Types of Reliability. Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals.
