Definitions:

Convergent Validity

When a scale correlates with other scales measuring the same construct.

Face Validity

When scale items appear, at face value, to measure what they are supposed to measure.

Convergent Validity

The degree to which two measures that theoretically should be related are actually related.

Discriminant Validity

The degree to which a concept or measurement is not associated with other concepts or measurements it's supposed to be unrelated to.
