| Question | Answer |
| Validity | The extent to which an instrument reflects the concept being examined. |
| Face validity | Items appear to reflect the concept they are supposed to test, (weakest form of validity). |
| Content validity | Items making up an instrument adequately represent the concept as rated by content experts. |
| Criterion-related validity | Outcomes of an instrument compare favorably to those from an established gold-standard criterion test. |
| Concurrent validity | Establishes validity of a target test when two measures (target test and gold-standard test) taken at the same time have similar results. |
| Predictive validity | Establishes validity of a target test when the target test predicts a future criterion score on a gold-standard test. |
| Construct validity | The ability of an instrument to differentiate among similar concepts. |
| Contrasting group validity | A type of construct validity in which groups known to be high or low on a characteristic are used to measure that construct. |
| Convergent validity | A type of construct validity in which measurements that should be related are related when two tests are used. (If scores converge, the same construct is being measured). |
| Divergent validity | A type of construct validity in which there are low or no correlations between scores on instruments measuring different characteristics by similar methods. |
| Factor | A combination or cluster of related observed variables that represents a specific underlying dimension of a construct. |
| Factor Analysis | Statistical procedure to determine if a set of items measure an underlying latent variable. Used to evaluate a questionnaire to determine if it is unidimensional or multidimensional. |
| Latent variable | Something that cannot be directly measured. |
| Exploratory Factor Analysis | Factor analysis performed on a set of items to determine underlying dimensions. Based on multiple general linear regression. |
| Confirmatory Factor Analysis | Factor analysis to determine if an underlying structure is consistent with theory or previous research. Performed with structural equation modeling. |
