An Index of Pseudo-Discrimination Loss (PDL-Index) has been developed for use with the recorded W-22 discrimination tests and is described. This PDL-Index is based on consideration of the kinds of errors made by the patient and provides an objective estimate of the relative contribution of extra-auditory influences to an obtained discrimination loss score. Good agreement was found between PDL-Index ratings and ratings by clinicians. Suggested interpretations of various PDL-Index values are presented.
