Alphamax: A Program that Maximizes Coefficient Alpha by Selective Item Deletion

Bruce Thompson

University of New Orleans, BBTELC{at}UNO

The presence report describes a computer program, ALPHAMAX, that can be employed to evaluate the internal consistency reliability of test data, and to help the researcher during test development in selecting item subsets that may maximize coefficient alpha. The program also invokes a "bootstrap" type logic to evaluate the generalizability of conclusions regarding optimal item subsets.
