The participants in the NIMH-MATRICS Consensus Development Conference on Negative Symptoms recommended that an instrument be developed that measured blunted affect, alogia, asociality, anhedonia, and avolition. The Brief Negative Symptom Scale (BNSS) is a 13-item instrument designed for clinical trials and other studies that measures these 5 domains. The interrater, test-retest, and internal consistency of the instrument were strong, with respective intraclass correlation coefficients of 0.93 for the BNSS total score and values of 0.89-0.95 for individual subscales. Comparisons with positive symptoms and other negative symptom instruments supported the discriminant and concurrent validity of the instrument.
参加 NIMH-MATRICS 共识会议的专家建议开发一种测量情感迟钝、言语贫乏、社会性缺乏、快感缺失和意志缺乏的工具。简短负性症状量表(BNSS)是一种为临床试验和其他研究设计的包含 13 个项目的工具,用于测量这 5 个领域。该工具的评定者间信度、重测信度和内部一致性均较强,总分的组内相关系数为 0.93,各分量表的值为 0.89-0.95。与阳性症状和其他负性症状量表的比较支持了该工具的区分效度和同时效度。
