Heterogeneity of emotional experience in schizophrenia: Trait affect profiles predict clinical presentation and functional outcome.

ABSTRACT: The current study examined whether subgroups of individuals with schizophrenia could be identified based on their profiles of trait positive and negative emotional experience, and whether those subgroups differed in their symptom presentation and functional outcome. Participants included 192 outpatients diagnosed with schizophrenia or schizoaffective disorder (SZ) and 149 demographically matched healthy controls who completed the trait version of the Positive and Negative Affect Scale, as well as symptom and functional outcome assessments. Cluster analysis determined whether patients could be separated into meaningful subgroups based on their trait emotional experience profiles, and discriminant function analysis determined whether these groups were valid and adequately separated.
