Convergent validity: How well a measure correlates with other hypothetically-related measures.

Construct validity: The extent to which a measure reflects the construct it was designed to evaluate.

Internal consistency: The extent to which items in a scale capture aspects of the same construct.

Test-retest: The degree to which measurement scores are consistent over a short period of time (usually 2 weeks).

Readability: The ease with which a reader can understand the questionnaire items.
