Of the 811 patients, 401 self-reported having sleep disorders and 410 denied them. Patients were predominantly male (66%), 84% lived accompanied, and the majority was professionally inactive (76%). There were no statistically significant differences between the groups regarding age, gender, educational level, employment status, age of diagnosis, illness duration, and type of antipsychotic treatment.
Patients self-reporting sleep disturbances were significantly more symptomatic (mean (SD) BPRS 12.8 (8.27) versus 16.6 (9.43), ).
Patients self-reporting sleep disturbances presented significantly worse family support (Chi2 = 2.2636, ) and self-reported worse SWL in all domains (Table 1). Caregivers of patients with schizophrenia self-reporting sleep disturbances also reported worse SWL in all domains, as compared to caregivers of patients without subjective sleep disturbances (Table 1).
