BACKGROUND Generic preference-based measures (EuroQoL-5D (EQ-5D) and SF-6D) are used in the economic evaluation of mental health interventions. However, there are inconsistent findings regarding their psychometric properties. AIMS To investigate the psychometric properties of the EQ-5D and SF-6D in different mental health conditions, using seven existing data-sets. METHOD The construct vali...

In this paper, we introduce a notion of generalized states from an EQ-algebra E1 to another EQ-algebra E2, which is a generalization of internal states (or state operators) on an EQ-algebra E. Also we give a type of special generalized state from an EQ-algebra E1 to E1, called generalized internal states (or GI-state). Then we give some examples and basic properties of generalized (internal) st...

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...

Research on L2 learners’ success at development and appropriate use of pragmatic ability and knowledge has mostly approached the issue from a cognitive or social perspective, and less attention has been devoted to the problem from the equally important emotional or individual-psychological lenses. This study sought to explore, first, the interplay between Iranian advanced EFL learners’ pragmati...

OBJECTIVES The objectives of this study included: (1) evaluation of the Polish version of Mother Generated-Index (MGI) as a tool for measuring antenatal Health Related Quality of Life (HRQL) of hospitalized women; (2) identification of factors influencing antenatal quality of life of hospitalized women; (3) assessment of correlations between MGI and SF-36v2, and between MGI and EQ-5D. MATERIA...

OBJECTIVE The Empathy Quotient (EQ) is a self-reported test developed by Baron-Cohen et al. (2004) to measure the cognitive and affective aspects of empathy. The purpose of this study was to develop a Korean version of EQ and to establish its psychometric properties based on a representative Korean sample. METHODS The Korean version of EQ and its correspondence with another popular measure of...

OBJECTIVE To assess the reliability and validity of the EuroQol (EQ-5D) for osteoarthritis of the knee (OA knee). METHODS Eighty-two patients with OA knee were asked to complete on two occasions, separated by 1 week, the EQ-5D, the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the 36-item short form of the Medical Outcomes Study (SF-36). RESULTS In this patient ...

BACKGROUND The English Department of Health has introduced routine collection of patient-reported outcome data for selected surgical procedures to facilitate patient choice and increase hospital accountability. However, using aggregate health outcome scores, such as EQ-5D utilities, for performance assessment purposes causes information loss and raises statistical and normative concerns. OBJE...

[Purpose] To clarify health-related quality of life (HR-QOL) in subjects with mild cognitive impairment (MCI), using EuroQOL (EQ-5D), and to investigate the relationship between HR-QOL and Tokyo Metropolitan Institute Gerontology Index of Competence (TMIG-IC) scores. [Subjects and Methods] The subjects included 25 women with MCI or frail constitutions. A variety of methods were used to assess m...
