Coding of cognitive input in delusional patients.

Constructed a manual for categorizing themes present in delusions, using interviews of a group of 6 females and 8 males representative of 68 currently delusional patients. Interjudge reliability for the manual's categories ranged from .73 to .93. A cognitive congruence hypothesis, which predicted that dominant themes in an S's delusional material would match the dominant categories used to construct his reality, was supported. The reality constructs obtained from 54 Ss on a Logical Consequences Test were significantly correlated with the dominant delusional themes. Moreover, males perceived significantly more negative interpersonal pressure, whereas females perceived significantly more negative sexual pressure. Both also perceived more negative pressure coming from the environment rather than from within, whereas a control group of 31 normal Ss did not.
