THE PICTURE DESCRIPTION TEST: RELIABILITY AND VALIDITY OF A HOMOGENEOUS SCALE.

Abstract : The report concerns three further studies conducted with the Picture Description Test (PDT) (Izard, Randall, and Cherry, 1963). The first study utilized an Army sample devising a key for that population which discriminated between three adjustment level groups. The second study devised a key for scoring tests at the high school level. In addition, other personality measures were correlated with PDT scores for subsets of this sample. The third study investigated the use of the PDT with hospitalized mental patients. There was no overlap or inversion of mean scores between the mean scores of patient and control groups, although the amount of variance prevented clearcut statistical separation of the two. (Author)
