Performance of high school students on the Edwards personal preference schedule.

Social Stratification and Some Personality Variables

“…This is consistent with the data from Hollingshead and Redlich (9, p. 8 5 ) , with Hollingshead's Elmtown's Youth (8, p. 287) and Warner's Jonesvifle (15). Dominance was also found to be discriminating among the classes in Klett's study (10).…”

“…In a study similar to our own, Klett (10) divided high school students into six classes on the basis of the occupation of the father, and found that only two of the Edwards Personal Preference Schedule variables, autonomy and dominance, were significantly related to socio-economic status. H e concluded that "the effect of socio-economic status on the EPPS variables failed to establish that this variable was profoundly related to the scores" (4, p. 70).…”

Effect of a training school experience on the personality of delinquent boys.

“…A recent article by Merrill and Heathers (1956) points up the complementary relationship between the MMPI, which evaluates personality structure, and the EPPS, which reflects the status of the motivational systems. Extensive norms for the EPPS on an adolescent population have been provided by Klett (1957).…”

“…Perhaps the outstanding feature of the EPPS comparisons between the two groups is the failure to find both pre and post differences on the great majority of the scales, many, if not all, which appear related to popular notions of characteristic aspects of delinquent activity. This instrument has already detected considerable differences between college and high school students (Klett, 1957) and males and females (Edwards,19 54). The conclusion that presents itself, therefore, is that the delinquent and nondelinquent boys of this study are, in fact, essentially similar in terms of most of their basic psychological needs as measured by the EPPS.…”

The stability of the social desirability scale values in the Edwards Personal Preference Schedule.

“…The Edwards Personal Preference Schedule (EPPS) (5) makes use of a forced-choice technique in which items pertaining to differing psychological needs but having comparable social desirability scale values are paired in an attempt to minimize the subjects' natural tendency to respond in the socially approved direction. In developing the EPPS, Edwards (4) scaled 140 items relating to 14 relatively independent, normal personality variables 8 drawn from a list of manifest needs described by Murray (9).…”
