Edwards Personal Preference Schedule (PPS)
AbstractReviews the test, by Allen L. Edwards (1953, 1954). The , a thoughtfully constructed instrument, embodies merits expressive of contemporary psychology. Although the author emphasizes the value of his schedule as an instrument for research, it comprises features which may prove to be of great merit in practical assessment. The is a modern instrument in the particular respects that it is designed to measure personality constructs which have a conceptual origin independent of the instrument itself; the subtests are not only reliable but relatively independent so that they are free from a confusing and uneconomical overlapping implication; and there is a built-in estimate of the reliability of the individual's performance in the form of a self-consistency score. The user also enjoys substantial protection from the possibility that the manifest need scores could be confounded to an important degree by the need to appear socially desirable. At the present time this reviewer finds only two aspects of the total procedure which may require some immediate attention. First, the relative homogeneity or heterogeneity of the scales with respect to the intercorrelations among their component items has not been examined. Second, the answer sheet, although faultlessly designed for the rapid scoring and collating of results, is a little tedious for the person who is taking the test. From the standpoint of scoring and interpretation, it would be very difficult indeed to conceive of a more convenient and agreeable procedure. The schedule is virtually self-scoring and the profile on the reverse of the answer sheet is self-interpreting.
