英文摘要 | Background/Purpose The remission and resolution criteria for schizophrenia were defined by the Remission in Schizophrenia Working Group in 2005, using eight core items of the positive and negative symptoms scale for schizophrenia. Subsequent studies of Caucasians have reported similar remission/resolution rates of approximately one-third. However, the remission/resolution rate in Chinese patients has not previously been reported. The present study assessed symptom resolution rates and associated factors among medicated and clinically stable Chinese schizophrenia patients. Methods Chinese patients with a diagnosis of schizophrenia were followed-up 1 month after their last psychiatric hospitalization. Cross-sectional clinical assessments for psychopathology, side effect profiles, quality of life, psychosocial function, and neurocognition tests were performed. Results Thirty-three (36.7%) of a total of 90 patients met the resolution criteria. They had a significantly higher level of education and lower scores for positive symptoms, negative symptoms, and general psychopathology on the positive and negative symptoms scale; they had lower scores on the Udvalg for Kliniske Undersøgelser Side Effect Rating Scale, and Simpson Angus Scale; and higher scores on the Global Assessment of Functioning and Subjective Well-being under Neuroleptics scales, compared with patients who did not meet the resolution criteria. Multiple regression analyses controlling for age, sex, duration of illness, education, duration of index hospitalization, and antipsychotic dosage revealed that a higher Udvalg for Kliniske Undersøgelser Side Effect Rating Scale score was related to lower rate of symptom resolution. The patients treated with clozapine and combinations of first generation antipsychotics and second generation antipsychotics had more severe psychopathology and side effects and showed a significantly lower resolution rate than did patients treated with first generation antipsychotics or second generation antipsychotics alone. Conclusion Consistent with studies of Caucasian patients, one-third of clinically stable Chinese patients met the resolution criteria, as well as having fewer general side effects, better global functioning and subjective well-being. |
