Summary
The Edwards Personal Preference Schedule has been administered to various groups of psychiatric patients as a way of investigating the need patterns of patient populations. Results have been interpreted to indicate differences in social desirability and the inappropriateness of the normative population sample. These interpreted results do occur when an inappropriate normative group is selected, i.e., college norms for adult populations, as the need score measures from the EPPS are age related. Results of a less dramatic but more useful nature emerge when the data from previous investigations are re-analyzed in terms of the adult norms.
