Predictors of residency status in chronically institutionalized and community dwelling schizophrenia patients.

Background: This cross-sectional study contrasted chronically hospitalized schizophrenia (SZ) spectrum disorder inpatients to SZ community dwelling patients on measures of psychopathology, social competence, neuropsychological performance and real-world functioning in order to discern factors predictive of patients' residency status and to characterize the contrasting ends of the SZ outcome continuum.

Method: Subjects included 26 chronic SZ patients hospitalized continuously on average for 12.8 years, and 26 SZ patients with a history of at least 18 months tenure in community placement.

Results: A series of multivariate analyses revealed both chronically hospitalized and community dwelling patients were similar in terms of their real world functioning abilities such as work skills, interpersonal skills, self-care skills and community engagement. Chronic SZ inpatients' manifested more severe functional competency and neurocognitive deficits relative to outpatients. Additionally, chronic inpatients were discriminated from community dwelling outpatients by their symptom severity and commitment of more socially undesirable/antisocial type behaviors.

Conclusions: Factors associated with chronic institutionalization are, in part, related to commission of antisocial type behaviors, as well as poor social and neurocognitive competences, and total symptom severity rather than deficits in everyday functional abilities.
