Item-reliability index measures the consistency of a particular item in a test. If the item is reliable, then it is consistent in measuring what it is intended to measure. Therefore, the higher the item-reliability index, the higher is the internal consistency of the test, which means the items are measuring the same construct, resulting in higher overall test reliability.
