BACKGROUND There is increasing interest in monitoring the health-related quality of life (HRQoL) of populations as opposed to clinical populations. The EQ-5D identifies five domains as being most able to capture the HRQoL construct. The question arises as to whether these domains are adequate within a community-based population or whether additional domains would add to the explanatory power of...

OBJECTIVE To compare the responsiveness of the EQ-5D index (German and British tariff), the EQ-5D visual analogue scale (EQ VAS), and time trade-off (TTO) scores in schizophrenia, affective disorders, and alcohol addiction. METHODS We used a sample of 502 patients and examined the measures at baseline and after 14 months. We used the generic "WHO Quality of Life BREF" (WHOQOL) and the disorde...

OBJECTIVES Several preference-based health-related quality of life (HRQoL) instruments have been published and widely used in different populations. However no consensus has emerged regarding the most appropriate instrument in therapeutic area of stable angina. This study compared and validated the psychometric properties of two generic preference-based instruments, the EQ-5D and SF-6D, among C...

Introduction: The EQ-5D allows the achievement of two essential components of any measure of health-related quality of life to be used in cost-utility economic evaluations: (i) a profile describing the health status in terms of domains or dimensions; and (ii) a numeric value associated with the health status described. Aim: The Portuguese version of the EQ-5D questionnaire was completed in 1998...

BACKGROUND AND OBJECTIVE The Korean version of the EQ-5D-Y was launched in 2015 by the EuroQol group. Currently, there is no HRQOL data obtained by using the EQ-5D-Y in Korea. This study aimed to measure health-related quality of life of Korean elementary school students using the EQ-5D-Y. METHODS Elementary school students were recruited from 11 primary schools in Gyungbuk, South Korea. The ...

OBJECTIVES To compare the discriminative power of the five-level version of the EuroQol five-dimensional questionnaire (EQ-5D-5L [5L]) and its three-level version (EQ-5D-3L [3L]) in patients with diabetes in Singapore. METHODS A consecutive sample of patients with type 2 diabetes mellitus (T2DM) self-completed the two versions of the EQ-5D in the clinic. The 3L index score was calculated from...

BACKGROUND The aim of this study was to measure HrQoL during acute exacerbations of COPD using generic and disease-specific instruments, and to assess completeness, proportion with best or worst health state, sensitivity to change and discriminative ability for each instrument. METHODS EQ-5D, SF-12 and SGRQ were obtained from COPD patients with GOLD stage III and IV hospitalized for an acute ...

BACKGROUND Older adults may find it problematic to attend hospital appointments due to the difficulty associated with travelling to, within and from a hospital facility for the purpose of a face-to-face assessment. This study aims to investigate equivalence between telephone and face-to-face administration for the Frenchay Activities Index (FAI) and the Euroqol-5D (EQ-5D) generic health-related...

BACKGROUND The EQ-5D, a generic health status questionnaire that is widely used in health economic evaluation, was recently expanded to the EQ-5D-5L to address criticisms of unresponsiveness and ceiling effect. AIMS To describe the validity, responsiveness and minimum important difference of the EQ-5D-5L in COPD. METHODS Study 1: The validity of the EQ-5D-5L utility index and visual analogu...
