Abstract
The problem of the unreliability of a single scale, test, or inventory has an extensive literature, while discussion regarding the reliability of a profile or battery of measurements cannot be found. A profile exists when an individual has been scored or rated on two or more measures. Unreliable profiles impose the difficulty that ordinal and interval relations among the individual's scores become uncertain or unstable. A profile reliability coefficient r,,(K) is derived to estimate the relative expected extent of this ordinal and interval "inversion" for any profile of K measures.
