| concurrent validity | An index of criterion-related validity used to predict performance in a real-life situation given at about the same time as the test or procedure; the extent to which the index from one test correlates with that of a nonidentical test or index; e.g., how well a score on an aptitude test correlates with the score on an intelligence test.

| concurrent disinfection | Application of disinfective measures as soon as possible after discharge of infectious material from the body of an infected person, or after soiling of articles with such infectious discharges. (05 Mar 2000) |

| concurrent review | Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment. (12 Dec 1998) |
| validity | 1. The extent to which a measurement, test or study measures what it purports to measure. 2. Occasionally, accuracy. (18 Nov 1997) |
| construct validity | The extent to which a test or procedure appears to measure a higher order, inferred theoretical construct, or trait in contrast to measuring a more limited, specific dimension; e.g., a sychrony in the scores on the Stanford-Binet Test, on a test of information processing, and the rate of glucose metabolism in the brain all are indices of intelligence. (05 Mar 2000) |
| content validity | The extent to which the items of a test or procedure are in fact a representative sample of that which is to be measured; e.g., items relating to ability in arithmetic and defining words are appropriate content for an intelligence test. (05 Mar 2000) |
| criterion-related validity | The degree of effectiveness with which performance on a test or procedure predicts performance in a real-life situation; e.g., a good correlation between a score on an intelligence test such as the Scholastic Aptitude Test and one's 4-year college grade point average. (05 Mar 2000) |
| predictive validity | Criterion-related validity used to predict performance in a real-life task at a future time. See: construct validity, criterion-related validity. (05 Mar 2000) |
| face validity | The extent to which the items of a test or procedure appear superficially to sample that which is to be measured. (05 Mar 2000) |
