| Abstract: | Evaluated the extent to which certain objective tests, ward behavior ratings, recorded verbalization scores, and interview behavior ratings possessed convergent and discriminant validity for 10 psychotic syndromes in a varied group of 125 psychotics drawn from 5 hospitals. A multimethod factor analysis was made of the 10 interview behavior and 12 ward behavior syndrome scores, and a similar analysis made of the entire set of 48 variables. The 1st analysis yielded 10 multimethod factors that corresponded closely to the original 10 interview syndromes. In the 2nd analysis, 12 interpretable factors were obtained, all of which exhibited convergent validity for 2 or 3 method sources. 1 or more objective test variables were meaningfully associated with each of the factors except 1. It is concluded that the convergent and discriminant validity of the syndromes is strongly supported. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
