Validity is
- Construct validity
- Content validity
- Face validity
In psychiatry there is a particular issue with assessing the validity of the diagnostic categories themselves. In this context (Kendell):
* content validity may refer to symptoms and diagnostic criteria; * concurrent validity may be defined by various correlates or markers, and perhaps also treatment response; * predictive validity may refer mainly to diagnostic stability over time; * discriminant validity may involve delimitation from other disorders.
To be valid, the result of a test has to accurately (i.e. reliably) answer the question that the test is intended to answer.
Reliability refers to consistency of a measuring instrument. Thus, reliability is necessary but not sufficient for validity. Inverse of reliability is "random error."
Measures of reliability include inter-rater reliability, test-retest reliability, and internal consistency reliability.
