The authors investigated the reliability and validity of the Scale of Functioning (SOF), a 15-item scale, in 78 middle-aged and elderly outpatients with schizophrenia. The SOF score had both high internal consistency and high interrater reliability and significantly discriminated between these patients and 45 normal comparison subjects. SOF scores correlated significantly with scores on several psychopathology rating scales as well as a number of existing instruments assessing cognitive or functional ability. Principal-components analysis using different scales of functional ability, psychopathology, and global cognitive performance and treated by orthogonal rotation revealed two domains of functioning, one of which was defined by the SOF along with scales for activities of daily living, negative symptoms, and cognitive impairment. The other domain was defined by scales for quality of well-being, social adjustment, and positive and depressive symptoms. Results support the construct validity of the SOF in late-life schizophrenia.
作者对78名中老年精神分裂症门诊患者进行了一项包含15个条目的功能量表（SOF）的信效度研究。SOF得分具有较高的内部一致性和评分者间信度，并且能显著区分这些患者与45名正常对照者。SOF得分与多个精神病理学评定量表以及一些现有的评估认知或功能能力的工具的得分显著相关。使用不同的功能能力、精神病理学和整体认知表现量表进行主成分分析，并经正交旋转处理后，揭示了两个功能领域，其中一个领域由SOF以及日常生活活动量表、阴性症状量表和认知损害量表定义。另一个领域由幸福感量表、社会适应量表以及阳性和抑郁症状量表定义。研究结果支持了SOF在老年精神分裂症中的结构效度。
