Abstract
In psychiatry, the use of rating scales as measures of outcome in clinical trials allows us to generate continuous outcome data, where each individual's outcome is measured in numbers. Continuous outcomes can be divided into two categories, such as improved and not improved, or may be kept continuous. This article briefly presents the main advantages and disadvantages of these two approaches, which are commonly employed in the analyses of rating scale scores in clinical trials and systematic reviews.
摘要
在精神病学中，使用评分量表作为临床试验的结果测量手段，可以生成连续的结果数据，其中每个人的结果都用数字来衡量。连续结果可以分为两类，例如改善和未改善，或者可以保持连续。本文简要介绍了这两种方法的主要优缺点，它们在临床试验和系统评价中评分量表分数分析中经常使用。
