126. Defeatist performance beliefs are associated with negative symptoms, cognition, and global functioning in individuals at clinical high-risk for psychosis
Defeatist performance beliefs (DPBs) play an important role in the cognitive model of negative symptoms and functioning. Prior research shows that greater DPB are associated with negative symptoms, neurocognitive performance, and lower functioning in individuals with schizophrenia. The present study examined whether individuals at clinical high-risk (CHR) for psychosis also display elevated DPBs and whether these are associated with negative symptoms, neurocognitive performance, and poor functioning. CHR individuals and healthy controls completed the DPB scale and measures of symptoms, cognitive performance, and functioning. Results showed greater DPBs among CHR compared to controls. Within the CHR group, greater DPB moderately correlated with greater negative symptom levels, lower neurocognitive performance, and lower social and vocational functioning. These findings suggest that the cognitive mode extends to the CHR population. DPB may be a propitious clinical target for early intervention to prevent or significantly reduce the development of negative symptoms, as well as declines in neurocognitive performance and functional outcome.
