Validating generic preference-base measures of health in mental health populations and estimating mapping functions

NHS必须在提供什么服务方面做出一些艰难的选择。做出这些选择的一种方法是通过观察服务提供的成本和收益来检查服务的金钱价值。NHS面临的一个主要问题是如何衡量一项服务的效益。越来越多地使用的一种效益衡量标准是质量调整生命年（QALYs），它衡量服务用户所经历的生活质量的提高。质量年的计算需要一些方法来评估接受服务的人的生活质量。目前通用的?健康措施主要是针对身体有问题的人制定的。本提案旨在严格审查计算质量质量年的两种主要措施。它包括对服务用户的采访，了解他们的生活质量，以及这些措施如何覆盖他们生活的这些方面。这项研究还将着眼于这些措施在以前的研究中在统计方面的表现如何。这项研究希望有助于改进研究人员评估治疗效果的方法。

The NHS has to make some tough choices about what services to provide. One way to make these choices is to examine the value for money of services by looking at the costs and benefits they provide. A major problem for the NHS is how to measure the benefits of a service. One measure of benefit that is becoming increasingly used is the quality adjusted life year (QALYs), which measures the gain in the quality of life experienced by the users of services. The calculation of QALYs requires some means of valuing the quality of life of people in receipt of services. Current ?generic? measures of health have been developed mainly for people with physical problems. This proposal aims to critically review two leading measures for calculating QALYs. It includes interviews with service users about their quality of life and how well these measures cover those aspects of their life. This study will also look at how well these measures have performed in statistical terms in previous studies. This study hopes to help improve the methods used by researchers in assessing the effectiveness of treatments.
