Factor structure of the Edwards personal preference schedule in a vocational rehabilitation sample

The 15 scales of the Edwards Personal Preference Schedule were factor analyzed for 450 male and 89 female vocational rehabilitation clients in order to compare results by gender as well as combining them to compare with the college norming data in the EPPS manual. Correlations and factors were similar in many ways when the combined sample and norm samples were compared, but larger and consistent differences between the study scores suggest that separate norms are justified and that norm tables need to be revised.
