There is growing interest in deficit symptoms in studies of the course and treatment response of schizophrenia. However, existing clinical assessment instruments focus primarily on productive symptoms. The authors describe the Quality of Life Scale (QLS), a 21-item scale based on a semistructured interview designed to assess deficit symptoms and thereby fill an important gap in the range of instruments now available. Data regarding reliability and training in the use of the QLS are presented. A factor analysis of the items yields results compatible with the conceptual model on which the scale is based. The factor analysis was also performed separately by sex and was fundamentally similar for men and women.
在精神分裂症病程及治疗反应的研究中，人们对缺陷症状的兴趣日益浓厚。然而，现有的临床评估工具主要关注阳性症状。作者介绍了生活质量量表（QLS），这是一个基于半结构化访谈的21项量表，旨在评估缺陷症状，从而填补现有工具范围中的一个重要空白。文中给出了关于QLS可靠性及使用培训的数据。对这些项目进行的因子分析得出的结果与该量表所基于的概念模型相符。因子分析还按性别分别进行，男性和女性的结果基本相似。
