AB  - Negative symptoms are a core feature of schizophrenia and account for much of the 
      long-term morbidity and poor functional outcome of people with schizophrenia. The 
      Brief Negative Symptom Scale (BNSS) was developed to address the main limitations 
      of the existing scales for the assessment of negative symptoms. The BNSS has been 
      translated into Italian, Spanish, German, Turkish and simplified Chinese versions 
      with excellent psychometric properties. In this study, a Chinese (traditional 
      script) version of the Brief Negative Symptom Scale (C-BNSS) was developed and 
      validated to facilitate future research on the Chinese population in Hong Kong. 
      Psychometric properties were examined in 149 individuals with schizophrenia. The 
      C-BNSS showed excellent internal consistency (alpha = 0.96), high inter-rater 
      reliability (intra-class correlation = 0.98), and high test-retest reliability 
      (Spearman's r = 0.96). Convergent validity was supported by high correlations 
      between C-BNSS total score and subscales with the Scale for Assessment of 
      Negative Symptoms (SANS), Negative Symptom subscale of the Positive and Negative 
      Syndrome Scale (PANSS), and Global Assessment of Functioning (GAF) score. 
      Discriminant validity was supported by low correlations between the C-BNSS total 
      score and the PANSS positive subscale, Calgary Depression Scale, and 
      Simpson-Angus Scale for extrapyramidal symptoms. The C-BNSS showed a five- factor 
      structure on Confirmatory Factor Analysis (CFA), confirming findings of previous 
      studies. Findings indicate that the C-BNSS demonstrates excellent psychometric 
      properties, which are comparable to the original English version. It is a 
      promising instrument for use in clinical trials as well as in clinical practice.
