“…The EQ-5D-5L includes a visual analog scale to indicate general health, with a score of zero reflecting worst health status and 100 indicating the best possible health status. Recent studies 25 – 29 suggest that the updated measure is both valid and reliable.…”

PurposeThere is growing interest in the management of long-term conditions and in keeping people active and participating in the community. Testing the effectiveness of interventions that aim to affect activities and participation can be challenging without a well-developed, valid, and reliable instrument. This study therefore aims to develop a patient-reported outcome measure, the Oxford Participation and Activities Questionnaire (Ox-PAQ), which is theoretically grounded in the World Health Organization’s International Classification of Functioning, Disability, and Health (ICF) and fully compliant with current best practice guidelines.MethodsQuestionnaire items generated from patient interviews and based on the nine chapters of the ICF were administered by postal survey to 386 people with three neurological conditions: motor neuron disease, multiple sclerosis, and Parkinson’s disease. Participants also completed the Medical Outcomes Study (MOS) 36-Item Short Form Health Survey (SF-36) and EQ-5D-5L.ResultsThus, 334 participants completed the survey, a response rate of 86.5%. Factor analysis techniques identified three Ox-PAQ domains, consisting of 23 items, accounting for 72.8% of variance. Internal reliability for the three domains was high (Cronbach’s α: 0.81–0.96), as was test–retest reliability (intraclass correlation: 0.83–0.92). Concurrent validity was demonstrated through highly significant relationships with relevant domains of the MOS SF-36 and the EQ- 5D-5L. Assessment of known-groups validity identified significant differences in Ox-PAQ scores among the three conditions included in the survey.ConclusionResults suggest that the Ox-PAQ is a valid and reliable measure of participation and activity. The measure will now be validated in a range of further conditions, and additional properties, such as responsiveness, will also be assessed in the next phase of the instrument’s development.

“… EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D) – is used for the assessment of the quality of life. The questionnaire contains five broad domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression 67,68. (Example of the item: USUAL ACTIVITIES (eg, work, study, housework, family or leisure activities): I have no problems doing my usual activities ▭; I have slight problems doing my usual activities ▭; I have moderate problems doing my usual activities ▭; I have severe problems doing my usual activities ▭; I am unable to do my usual activities ▭).…”

“…The additional measure is the EQ-5D visual analog scale (VAS). EQ-5D is extensively used in various countries in different clinical areas with good validity and reliability 68–71 Demographic questionnaire (DD) checked the necessary information such as proband age, marital and partnership status, employment status, education, pension status, subjective overall psychological well-being, and average physical activity during a week.…”

Purpose The investigation aimed to explore the association between personality traits, stressful life events, quality of life on anthropometric characteristics (waist/height ratio and percentage of visceral fat). Method A total of 227 participants took part in this cross-sectional study. Participants completed the Social Readjustment Rating Scale (SRRS), Temperament and Character Inventory-Revised, Type-D Scale (DS-14), EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D), and demographic questionnaire. Two anthropometric parameters were measured: Waist/height ratio and Percentage of the visceral fat. Results The average age of participants was 39.6±12.9 years, 60.4% women. The 41.8% of participants were overweight or obese. Regression analysis found a significant link between Harm-avoidance and EQ-5D visual analog scale (VAS) with Waist/height ratio in women and Reward dependence and Cooperativeness with Waist/height ratio in men. In regression analysis, the score of life events (SRRS) has statistically significant linked to Percentage of the visceral fat in women. The regression analysis also found a significant link between Novelty seeking, DS14, Negative affectivity, and EQ-5D VAS with Percentage of the visceral fat in women. Conclusion Significant associations between live events, personality traits, and body anthropometric measures were recognized. The differences were recognized between women and men. Outcomes propose some promising tools by which personality factors may influence overweight and obesity.

“…The convergent validation was for strong correlations between postulated dimensions and other dimensions that should, in theory, be considered relevant [49]. Thus, correlations of the ve dimensions (mobility, usual activities, self-care, pain/discomfort, and anxiety/depression) with other respective dimensions of other different instrument(s) are often evaluated for convergent validation purposes [46][47][48]. Meanwhile, the known-groups validation to evaluate the sensitiveness of the instrument is expected to yield distinctive results among different groups of patients [44,47].…”

PurposeThis study aims to provide EQ-5D-5L reference data of the general Vietnamese population and to test the EQ-5D-5L’ known-groups validity among people living with hypertension in Vietnam.MethodsThe EQ-5D-5L population norms were obtained via a representative sample from a general population of 1200 adults. Outcomes of the population norms were presented through five dimensions and five levels, EQ-VAS, and EQ-5D-5L indexes. Descriptive statistics of these outcomes were categorised by gender and age groups. Evidence of the known-groups validity was based on a sample of 577 non-hypertensive adults, 242 individuals with undiagnosed and 477 individuals with diagnosed hypertension. A hypothesis was formulated that people with worse health status would have lower EQ-VAS and EQ-5D-5L indexes. ResultsFor the EQ-5D-5L population norms, 54.4% of the respondents reported having full health. The mean EQ-VAS and EQ-5D-5L indexes were 81.10 and 0.94, respectively. The EQ-VAS and EQ-5D-5L indexes were higher among males, people at younger ages, those with more education, a paid job, and single. The mean EQ-VAS and EQ-5D-5L indexes of people in the diagnosed hypertension group were statistically significantly lower than they were in the other two groups. ConclusionThe EQ-5D-5L population norms were derived for the Vietnamese general population. The EQ-5D-5L can distinguish the quality-of-life differences among Vietnamese with hypertension.
