Reliability refers to the consistency of a measure, while validity refers to the accuracy of a measure in assessing the intended construct. A measure could be consistent (reliable) in giving the same result every time it is administered, but if it is not measuring what it is intended to measure (invalid), then it is useless. Therefore, reliability is essential for validity, but validity is not solely dependent on reliability.
