Brief summary

This is a trial investigating how providing detailed desciptors of a very good, and very bad health state affect the way people rate their own health-related quality of life. Health-related quality of life can be difficult to measure. Giving detailed description of extreme health states may help participants to "put into perspective" their current health states. This may result in reporting a different level of health than they would report if no detailed descriptors were given.

Interventions

This study involves two interventions: Intervention A - providing detailed descriptors for the upper anchor point on a visual analogue scale of health-related quality of life (part of EQ-5D instrument). The duration of intervention A was the time taken to read the descriptors (less than 5 minutes). Intervention B - providing detailed descriptors for the lower anchor point on a visual analogue scale of health-related quality of life (part of EQ-5D instrument). The duration of intervention B was the time taken to read the descriptors (less than 5 minutes). The descriptors to be used in each intervention will be those descriptors used in another validated health-related quality of life measurement instrument, the AQoL (Assessment of Quality of Life).
