Background: Quality of life is paramount for patients and clinicians, but existing measures of health were not developed for routine use.
Objectives: This paper describes the development and testing of a new generic tool for measuring health related quality of life (HRQoL) with direct comparison to the SF-12 Health Survey.
Methods: The new tool (howRu) has four items (discomfort, distress, disability and dependence), rated using four levels (none, a little, quite a lot and extreme), providing 256 possible states (4(4)); it has an aggregate scoring scheme with a range from 0 (worst) to 12 (best).
