Definitions
Face validity: How well a measure appears to represent the construct it is supposed to be measuring.
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.
Key
- Green: Meets validation criteria
