A Comparison of Computerised Versus Interviewer-administered Approach for Assessing Health-related Quality of Life


Phase N/A Results N/A

Trial Description

The aim of this study is to compare a multimedia, computerised approach vs. interviewer administration of health-related quality of life (HRQoL) instruments.

Detailed Description

There are no drug treatments involved in this study. The administration of health-related quality of life questionnaires is the intervention being studied. Health-related quality of life questionnaires measure the physical, mental and social well-being of an individual, are recognised as important patient-reported outcomes and are increasingly being used in clinical trials and routine clinical practice. By asking study participants to complete a questionnaire assessing their physical, mental and social well-being, we are increasing their awareness of these aspects of their health and may directly or indirectly prompt them to take actions and/ or have thoughts that may improve or worsen their health status. Hence, we have considered this an interventional study. This survey will be conducted in Chinese.
