Delusional verbalizations and beliefs

This study evaluated the intensity of delusional beliefs during the modification of delusional verbalizations with three chronically mentally ill inpatients. The multiple‐baseline across responses design was used to evaluate the efficacy of a behavioral treatment package to modify delusional verbalizations. Results revealed that changes were obtained in delusional verbalizations to personal questions without corresponding changes in the subjects' delusional beliefs. Changes in delusional verbalizations were well‐maintained for two subjects during a 6‐month follow‐up period. Mixed results were obtained for generalization probe interviews.
