Two studies (1, 2) have indicated that a majority of the SO items on Taylor's Manifest Anxiety Scale (MAS) are not valid in predicting clinical criteria of manifest anxiety. The consistency in item validity results of independent studies suggests that a shortened form of the MAS, retaining only the valid items, might be more useful and clinically valid than the standard MAS. However, such a shortened MAS might lack the desirable normative characteristics, such as high reliability, of the longer MAS.The 20 most consistently valid MAS items in the reports noted above (Item 1-16 and 29-32 in 2, p. 360) were selected as a shortened form of the MAS. The SO-item MAS was administered to 744 college 5s and their papers scored for the 20-item scale. The 20item scale, omitting the 30 "nonvalid" items, was given to an additional 324 5s. No significant differences in scale means or variances were found for the two methods of administration, nor were any sex differences 1 An extended report of this study may be obtained without charge from A.
