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.

Interventions

  • Other: Health-related quality of life assessment
    • Study participants will be asked to complete the following health-related quality of life questionnaires: EQ-5D, Health Utilities Index 3, SF-8 and SF-6D. The Singapore (Chinese) versions of these questionnaires have been previously tested and validated in a pilot cohort of the same study population.
