Test-retest reliability refers to the consistency of a measurement when taken at different times with the same instrument. If the same instrument consistently gives the same results every time it is used, then it would indicate good test-retest reliability. Equivalent-forms reliability measures consistency across different forms of the same assessment. Internal consistency refers to the interrelatedness of items within a single assessment. Internal validity refers to the degree to which an assessment measures what it is intended to measure, while external validity refers to the extent to which findings can be generalized to other situations or populations.
