Reliability Improvement Reliability of a scale is improved by pruning of weak items. Deleting a weak item from a measurement scale may sometimes lead to jeopardizing scale’s theoretical construct. When this happens‚ the item needs to be redesigned and revaluated. Wording of items in a measurement scale plays an important role in determining its discriminating power. Weak items in the scale are identified by computing Corrected Item-Total Correlation (CITC) (Ferketich‚ 1991) and Item-Deleted Cronbach’s
