Prevalence and correlated factors of deficit schizophrenia in community-dwelling patients with schiz-ophrenia / 中华行为医学与脑科学杂志

ABSTRACT

Objective To explore the prevalence,socio-demographic and clinical characteristics of deficit schizophrenia in Chinese community-dwelling patients with schizophrenia. Methods Five hundred and three community-dwelling patients with schizophrenia were recruited in a cross-sectional study in Yuhua-tai District of Nanjing,and deficit schizophrenia was confirmed by Chinese version of the Schedule for the Deficit Syndrome (SDS). Their socio-demographic and clinical characteristics were collected. All patients' psychopathology was assessed by Positive and Negative Syndrome Scale (PANSS). Results The current prevalence of community-dwelling patients with deficit schizophrenia was 0. 67‰. Deficit schizophrenia had significantly higher hospitalizations((2. 4±1. 3)times,(1. 9±0. 9)times),PANSS negative scores((28. 4± 8. 1),(17. 7±6. 3)),PANSS total score((96. 5±17. 3),(87. 3±18. 1)) than non-deficit schizophrenia(all P<0. 05),while non-deficit schizophrenia had higher currently smoking rate,positive scores,marriage per-centage and age of onset( all P<0. 05) . Further multiple logistic regression analysis indicated that male sex, age of onset,smoking and negative PANSS score were independently associated with deficit schizophrenia. Conclusion The study showed that deficit schizophrenia is very common in Chinese psychiatric outpatients. The results partially support deficit schizophrenia as an independent subtype of schizophrenia.
