目的：简明阴性症状量表(BNSS)是一种简明的工具，用于评估精神分裂症患者的阴性症状，涵盖五个阴性症状领域，适用于临床、实验和流行病学环境。到目前为止，BNSS的原始版本和翻译版本已被证明具有足够的心理测量学特性。本研究旨在检验BNSS日文版的内部一致性、评分者间和重测信度、判别效度和收敛效度以及因子结构。信度用Cronbach‘sα计算内部一致性，用组内相关系数(ICC)计算评分者间信度。计算皮尔逊相关系数，估计重测信度。除BNSS外，还编制了阴性症状评定量表(SANS)和阳性症状评定量表(SAPS)，以评定收敛效度和区分效度。结果：日本BNSS具有良好的内部一致性(Cronbach‘sα=0.95)、评分者间信度(类内相关系数=0.97)和重测信度(r=0.94，p
Purpose: The brief negative symptoms scale (BNSS) is a concise instrument used to assess negative symptoms of subjects with schizophrenia covering five domains of negative symptoms and is suitable for use in clinical, experimental, and epidemiological settings. The original and translated version of BNSS has thus far been shown to have adequate psychometric properties. This study aimed to examine internal consistency, inter-rater and test-retest reliability, discriminant and convergent validity, and factor structure of the Japanese version of BNSS.Patients and methods: The assessment was performed by 11 raters using interview videos of nine subjects. Reliability was calculated with Cronbach's alpha for internal consistency and intra class correlation coefficient (ICC) for inter-rater reliability. Pearson's correlation coefficients were calculated to estimate the test-retest reliability. In addition to BNSS, Scale for assessment of negative symptoms (SANS) and scale for assessment of positive symptoms (SAPS) was obtained to assess the convergent and discriminant validity. Factor structure was assessed using principle factor analysis.Results: The Japanese BNSS showed excellent internal consistency (Cronbach's alpha=0.95), inter-rater reliability (intra class correlation coefficient=0.97), and test-retest reliability (r=0.94, p
