Brief summary

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.

Interventions

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.
