validity

The content of the measure appears to reflect the construct being measured.

Face Validity

If the new measure of depression includes items like "I feel sad"
or "I feel down" or "I cry a lot," then it would have evidence for being face-valid.

Face Validity

The content of the measure is linked to the universe of content that defines the construct.

Content Validity

Depression is defined by a mood and by cognitive and physiological symptoms. If the new measure of depression was content-valid, it would include items from each of these domains.

Content Validity

Scores on the measure pre- dict behavior on a criterion measured at a future time

Predictive Validity

If the measure of depression predicts future diagnosis of depression, then it would have evidence of predictive validity.

Predictive Validity

Scores on the measure
are related to a criterion measured at the same time (concurrently).

Concurrent Validity

If two groups of participants were given the measures, and they differed in predictable ways (e. g, if those in therapy for depression scored higher than those in therapy for an anxiety disorder), then this would be evidence for concurrent validity.

Concurrent Validity

Scores on the measure are related to other measures of the same construct.

Convergent Validity

If scores from the new measure, collected at the same time as other measures of depression (e.g., Beck Depression Inventory or Duke Anxiety-Depression Scale), were related to scores from those other measures, then it could be said to have evidence for con

Convergent Validity

Scores on the measure are not related to other measures that are theoretically different.

Discriminant Validity

If the new measure, collected at the same time as other mea- sures of anxiety (e.g., state/trait anxiety), was unrelated to those measures, then it could be said to have evidence for discrimi- nant validity because it would indicate that what was being me
