Factor Score Reliabilities and Domain Validities

Richard L. Gorsuch

Graduate School of Psychology Fuller Theological Seminary

Kaiser and Michael (1977) reported a formula for factor scores giving an internal consistency reliability (generalized KR 20) and its square root, the domain validity. The use of this formula is found to be inappropriate if variables are included which have trivial weights for the factor for which the score is being computed. The problem can be corrected by considering only the salient variables.
