Current methods of ranking or scoring disability tend to be arbitrary. A new method is put forward on the hypothesis that disability progresses in regular, cumulative patterns. A model of disability is defined and tested with the use of Guttman scale analysis. Its validity is indicated on data from a survey in the community and from postsurgical patients, and some factors involved in scale variation are identified. The model provides a simple measurement technique and has implications for the assessment of individual disadvantage, for the prediction of progress in recovery or deterioration, and for evaluation of the outcome of treatment regimes.
目前对残疾进行排名或评分的方法往往具有随意性。基于残疾以规律的累积模式发展这一假设,提出了一种新方法。通过使用古特曼量表分析来定义和测试残疾模型。该模型在社区调查数据和术后患者数据上显示出有效性,并确定了量表变化所涉及的一些因素。该模型提供了一种简单的测量技术,对个体劣势评估、恢复或恶化进展预测以及治疗方案效果评估都有启示意义。
