Abstract
AIM To assess and compare the measurement properties of EQ-5D-5L and SF-6Dv2 among lymphoma patients in China. METHODS A face-to-face survey of Chinese lymphoma patients was conducted at baseline (all types) and follow-up (diffuse large B-cell). EQ-5D-5L and SF-6Dv2 health utility scores (HUSs) were calculated using the respective Chinese value sets. Ceiling effect was assessed by calculating the percentage of respondents reporting the optimal health state. Convergent validity of EQ-5D-5L and SF-6Dv2 was assessed using the Spearman rank correlation coefficient (r) with QLQ-C30 as a calibration standard. Known-groups validity of the two HUSs was evaluated by comparing their scores of patients with different conditions; and their sensitivity was further assessed in the known-groups using relative efficiency (RE). Test-retest reliability and responsiveness was tested using ICC and standardized response mean (SRM), respectively. RESULTS Altogether 200 patients were enrolled at baseline and 78 were followed up. No ceiling effect was found for SF-6Dv2 compared to 24.5% for EQ-5D-5L. Correlation between the two HUSs and with QLQ-C30 score was strong (r > 0.5). Each dimension of EQ-5D-5L and SF-6Dv2 had moderate or greater correlations with similar dimensions of QLQ-C30 (r > 0.35). Both EQ-5D-5L and SF-6Dv2 could only a minority known-groups, and the latter may have better sensitivity. EQ-5D-5L had better test-retest reliability (ICC = 0.939); while both of them were responsive to patients with worsened and improved clinical status. CONCLUSIONS EQ-5D-5L and SF-6Dv2 were found to have good convergent validity and responsiveness, while EQ-5D-5L had better test-retest reliability and higher ceiling effect. Not enough evidence indicates which of the two measures has better known-group validity and sensitivity.

Xie S, Wu J, Chen G. Comparative performance and mapping algorithms between EQ-5D-5L and SF-6Dv2 among the Chinese general population. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2024; 25:7-19. [PMID: 36709458 DOI: 10.1007/s10198-023-01566-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Accepted: 01/11/2023] [Indexed: 06/18/2023]
Abstract
OBJECTIVES To explore the comparative performance and develop the mapping algorithms between EQ-5D-5L and SF-6Dv2 in China. METHODS Respondents recruited from the Chinese general population completed both EQ-5D-5L and SF-6Dv2 during face-to-face interviews. Ceiling/floor effects were reported. Discriminative validity in self-reported chronic conditions was investigated using the effect sizes (ES). Test-retest reliability was evaluated using intra-class correlation coefficient (ICC) and Bland-Altman plots in a subsample. Correlation and absolute agreements between the two measures were estimated with Spearman's rank correlation coefficient and ICC, respectively. Ordinary least squares (OLS), generalized linear model, Tobit model, and robust MM-estimator were explored to estimate mapping equations between EQ-5D-5L and SF-6Dv2. RESULTS 3320 respondents (50.3% males; age 18-90 years) were recruited. 51.1% and 12.2% of respondents reported no problems on all EQ-5D-5L and SF-6Dv2 dimensions, respectively. The mean EQ-5D-5L utility was higher than SF-6Dv2 (0.947 vs. 0.827, p < 0.001). Utilities were significantly different across all chronic conditions groups for both measures. The mean absolute difference of utilities between the two tests for EQ-5D-5L was smaller (0.033 vs. 0.043) than SF-6Dv2, with a slightly higher ICC (0.859 vs. 0.827). Fair agreement (ICC = 0.582) was observed in the utilities between the two measures. Mapping algorithms generated by the OLS models performed the best according to the goodness-of-fit indicators. CONCLUSIONS Both measures showed comparable discriminative validity. Systematic differences in utilities were found, and on average, the EQ-5D-5L generates higher values than the SF-6Dv2. Mapping algorithms between the EQ-5D-5L and SF-6Dv2 are reported to enable transformations between these two measures in China.

Assessment of health-related quality of life in individuals with depressive symptoms: validity and responsiveness of the EQ-5D-3L and the SF-6D. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2023; 24:1297-1307. [PMID: 36385438 PMCID: PMC10533591 DOI: 10.1007/s10198-022-01543-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 10/24/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND The EQ-5D and the SF-6D are examples of commonly used generic preference-based instruments for assessing health-related quality of life (HRQoL). However, their suitability for mental disorders has been repeatedly questioned. OBJECTIVE To assess the responsiveness and convergent validity of the EQ-5D-3L and SF-6D in patients with depressive symptoms. METHODS The data analyzed were from cardiac patients with depressive symptoms and were collected as part of the SPIRR-CAD (Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease) trial. The EQ-5D-3L and SF-6D were compared with the HADS (Hospital Anxiety and Depression Scale) and PHQ-9 (Patient Health Questionnaire) as disease-specific instruments. Convergent validity was assessed using Spearman's rank correlation. Effect sizes were calculated and ROC analysis was performed to determine responsiveness. RESULTS Data from 566 patients were analysed. The SF-6D correlated considerably better with the disease-specific instruments (|rs|= 0.63-0.68) than the EQ-5D-3L (|rs|= 0.51-0.56). The internal responsiveness of the SF-6D was in the upper range of a small effect (ES: - 0.44 and - 0.47), while no effect could be determined for the EQ-5D-3L. Neither the SF-6D nor the EQ-5D-3L showed acceptable external responsiveness for classifying patients' depressive symptoms as improved or not improved. The ability to detect patients whose condition has deteriorated was only acceptable for the EQ-5D-3L. CONCLUSION Overall, both the convergent validity and responsiveness of the SF-6D are better than those of the EQ-5D-3L in patients with depressive symptoms. The SF-6D appears, therefore, more recommendable for use in studies to evaluate interventions for this population.

Health Qual Life Outcomes 2023; 21:118. [PMID: 37904216 PMCID: PMC10617156 DOI: 10.1186/s12955-023-02202-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 10/23/2023] [Indexed: 11/01/2023] Open
Abstract
OBJECTIVE To evaluate and compare the measurement properties of the EQ-5D-5L and SF-6Dv2 among Chinese overweight and obesity populations. METHODS A representative sample of Chinese overweight and obesity populations was recruited stratified by age, gender, body mass index (BMI), and area of residence. Social-demographic characteristics and self-reported EQ-5D-5L and SF-6Dv2 responses were collected through the online survey. The agreement was assessed using intraclass correlation coefficients (ICC). Convergent validity and known-group validity were examined using Spearman's rank correlation and effect sizes, respectively. The test-retest reliability was assessed using among a subgroup of the total sample. Sensitivity was compared using relative efficiency and receiver operating characteristic. RESULTS A total of 1000 respondents (52.0% male, mean age 51.7 years, 67.7% overweight, 32.3% obesity) were included in this study. A higher ceiling effect was observed in EQ-5D-5L than in SF-6Dv2 (30.6% vs. 2.1%). The mean (SD) utility was 0.851 (0.195) for EQ-5D-5L and 0.734 (0.164) for SF-6Dv2, with the ICC of the total sample was 0.639 (p < 0.001). The Spearman's rank correlation (range: 0.186-0.739) indicated an acceptable convergent validity between the dimensions of EQ-5D-5L and SF-6Dv2. The EQ-5D-5L showed basically equivalent discriminative capacities with the SF-6Dv2 (ES: 0.517-1.885 vs. 0.383-2.329). The ICC between the two tests were 0.939 for EQ-5D-5L and 0.972 for SF-6Dv2 among the subgroup (N = 150). The SF-6Dv2 had 3.7-170.1% higher efficiency than the EQ-5D-5L at detecting differences in self-reported health status, while the EQ-5D-5L was found to be 16.4% more efficient at distinguishing between respondents with diabetes and non-diabetes. CONCLUSIONS Both the EQ-5D-5L and SF-6Dv2 showed comparable reliability, validity, and sensitivity when used in Chinese overweight and obesity populations. The two measures may not be interchangeable given the systematic difference in utility values between the EQ-5D-5L and SF-6Dv2. More research is needed to compare the responsiveness.

Abstract
PURPOSE There is limited research exploring the usefulness of generic preference-based quality of life (GPQoL) measures used to facilitate economic evaluation in the context of posttraumatic stress disorder (PTSD). The aim of the current study was to explore the validity and responsiveness of a common GPQoL measure (Assessment of Quality of Life 8 Dimension [AQoL-8D]) in relation to a PTSD condition-specific outcome measure (Posttraumatic Stress Disorder Checklist for the DSM-5 [PCL-5]). METHOD This aim was investigated in a sample of individuals (N = 147) who received trauma-focused cognitive-behavioural therapies for posttraumatic stress disorder. Convergent validity was investigated using spearman's correlations, and the level of agreement was investigated using Bland-Altman plots. Responsiveness was investigated by exploring the standardised response means (SRM) from pre-post-treatment across the two measures, which allow the comparison of the magnitude of change between the measures over time. RESULTS Correlations between the AQoL-8D (dimensions, utility and summary total scores) and the PCL-5 total score ranged from small to large and agreement between the measures was considered moderate to good. While SRMs were large for the AQoL-8D and PCL-5 total scores, the SRM for the PCL-5 was nearly double that of the AQoL-8D. CONCLUSION Our findings demonstrate that the AQoL-8D has good construct validity but present preliminary evidence that economic evaluations using only GPQoL measures may not fully capture the effectiveness of PTSD treatments.

Abstract
BACKGROUND Self-harm is an important predictor of a suicide death. Culturally appropriate strategies for the prevention of self-harm and suicide are needed but the evidence is very limited from low- and middle-income countries (LMICs). This study aims to investigate the effectiveness of a culturally adapted manual-assisted problem-solving intervention (CMAP) for patients presenting after self-harm. METHODS This was a rater-blind, multicenter randomised controlled trial. The study sites were all participating emergency departments, medical wards of general hospitals and primary care centres in Karachi, Lahore, Rawalpindi, Peshawar, and Quetta, Pakistan. Patients presenting after a self-harm episode (n = 901) to participating recruitment sites were assessed and randomised (1:1) to one of the two arms; CMAP with enhanced treatment as usual (E-TAU) or E-TAU. The intervention (CMAP) is a manual-assisted, cognitive behaviour therapy (CBT)-informed problem-focused therapy, comprising six one-to-one sessions delivered over three months. Repetition of self-harm at 12-month post-randomisation was the primary outcome and secondary outcomes included suicidal ideation, hopelessness, depression, health-related quality of life (QoL), coping resources, and level of satisfaction with service received, assessed at baseline, 3-, 6-, 9-, and 12-month post-randomisation. The trial is registered on ClinicalTrials.gov. NCT02742922 (April 2016). RESULTS We screened 3786 patients for eligibility and 901 eligible, consented patients were randomly assigned to the CMAP plus E-TAU arm (n = 440) and E-TAU arm (N = 461). The number of self-harm repetitions for CMAP plus E-TAU was lower (n = 17) compared to the E-TAU arm (n = 23) at 12-month post-randomisation, but the difference was not statistically significant (p = 0.407). There was a statistically and clinically significant reduction in other outcomes including suicidal ideation (- 3.6 (- 4.9, - 2.4)), depression (- 7.1 (- 8.7, - 5.4)), hopelessness (- 2.6 (- 3.4, - 1.8), and improvement in health-related QoL and coping resources after completion of the intervention in the CMAP plus E-TAU arm compared to the E-TAU arm. The effect was sustained at 12-month follow-up for all the outcomes except for suicidal ideation and hopelessness. On suicidal ideation and hopelessness, participants in the intervention arm scored lower compared to the E-TAU arm but the difference was not statistically significant, though the participants in both arms were in low-risk category at 12-month follow-up. The improvement in both arms is explained by the established role of enhanced care in suicide prevention. CONCLUSIONS Suicidal ideation is considered an important target for the prevention of suicide, therefore, CMAP intervention should be considered for inclusion in the self-harm and suicide prevention guidelines. Given the improvement in the E-TAU arm, the potential use of brief interventions such as regular contact requires further exploration.

Abstract
OBJECTIVES The current study aimed to map the disease-specific Schizophrenia Quality of Life Scale (SQLS) onto the three- and five-level EuroQol five-dimension (EQ-5D-3 L and EQ-5D-5 L), Health Utility Index Mark 3 (HUI3) and Short Form six-dimensional (SF-6D) preference-based instruments to inform future cost-utility analyses for treatment of patients with schizophrenia. METHODS Data from 251 outpatients with schizophrenia spectrum disorders was included for analysis. Ordinary least square (OLS), Tobit and beta regression mixture models were employed to estimate the utility scores. Three regression models with a total of 66 specifications were determined by goodness of fit and predictive indices. Distribution of the original data to the distributions of the data generated using the preferred estimated models were then compared. RESULTS EQ-5D-3 L and EQ-5D-5 L were best predicted by the OLS model, including SQLS domain scores, domain-squared scores, age, and gender as explanatory predictors. The models produced the best performance index and resembled most closely with the observed EQ-5D data. HUI3 and SF-6D were best predicted by the OLS and Tobit model respectively. CONCLUSION The current study developed mapping models for converting SQLS scores into generic utility scores, which can be used for economic evaluation among patients with schizophrenia.

Abstract
PURPOSE This study aims to systematically review the literature on health utility in depression generated by time trade-off (TTO) method and to compare health state vignettes. METHODS Systematic literature search was conducted following PRISMA guideline in 2020 November (updated in 2022 March) in Pubmed, Web of Science, PsycInfo, and Cochrane Database of Systematic Reviews. Random effect meta-analysis was conducted to pool vignette-based utility values of mild, moderate, and severe depression and to compare the preferences of depressed and nondepressed population. RESULTS Overall, 264 records were found, 143 screened by title and abstract after removing duplicates, 18 assessed full text, and 14 original publications included. Majority of the studies (n = 9) used conventional TTO method, and most of the studies (n = 8) applied 10-year timeframe. Eight studies evaluated self-experienced health (own-current depression). Six studies assessed vignette-based health states of remitted, mild, moderate, and severe depression, half of them applied McSad measure based health description. Altogether, 61 different utility values have been cataloged, mean utility of self-experienced depression states (n = 33) ranged between 0.89 (current-own depression) and 0.24 (worst experienced depression). Pooled utility estimates for vignette-based mild, moderate, and severe depression was 0.75, 0.66 and 0.50, respectively. Meta-regression showed that severe depression (β = -0.16) and depressed sample populations (β = -0.13) significantly decrease vignette-based utility scores. CONCLUSION Our review revealed extent heterogeneity both in TTO methodology and health state vignette development. Patient's perception of depression health states was worse than healthy respondents.

Abstract
INTRODUCTION Euro-Qol-5 Dimension (EQ-5D) and Short-Form 6-Dimension (SF-6D) are the most commonly used generic multi-attribute utility instruments (MAUI) to calculate quality-adjusted life-years (QALYs) in East and South-East Asia. This study aims to systematically review and summarize current evidence on comparing measurement properties of EQ-5D and SF-6D in East and South-East Asian populations. AREAS COVERED Guided by the PRISMA systematic review and meta-analysis guidelines, a systematic literature search was conducted in databases of PubMed, Web of Science, MEDLINE, EMBASE and CINAHL (until June 2022) to obtain studies which compared measurement properties (feasibility, reliability, validity, responsiveness, and sensitivity) and agreement of EQ-5D and SF-6D in the populations. EXPERT OPINION In general, both EQ-5D and SF-6D had good measurement properties in East and South-East Asian populations; but their utility scores cannot be used interchangeably. Compared to the 3-level EQ-5D, SF-6D had better sensitivity and lower ceiling effects, but the comparison results between the 5-level EQ-5D and SF-6D were inconsistent across populations. This scoping review found that most studies did not consider order effects, did not specify the versions of SF-6D, and ignored certain measurement properties (reliability, content validity, and responsiveness). These aspects need to be further explored in future studies.

Abstract
BACKGROUND The most appropriate preference-based health-related quality of life (HRQoL) instruments for trials or research studies that ascertain the consequences of individuals born very preterm and/or low birthweight (VP/VLBW) are not known. Agreement between the HUI3 and SF-6D multi-attribute utility measures have not been previously investigated for VP/VLBW and normal birthweight or term-born controls. This study examined the agreement between the outputs of the HUI3 and SF-6D measures among adults born VP/VLBW and normal birthweight or term born controls. METHODS We used two prospective cohorts of individuals born VP/VLBW and controls contributing to the 'Research on European Children and Adults Born Preterm' (RECAP) consortium which assessed HRQoL using two preference-based measures. The combined dataset of individual participant data (IPD) included 407 adult VP/VLBW survivors and 367 controls, ranging in age from 18 to 26 years. Bland-Altman plots, intra-class correlation coefficients, and generalized linear mixed models in a one-step approach were used to examine agreement between the measures. RESULTS There was significant discordance between the HUI3 and SF-6D multi-attribute utility measures in the VP/VLBW sample, controls, and in the combined samples. Agreement between the HUI3 and SF-6D multi-attribute utility measures was weaker in controls compared with VP/VLBW individuals. CONCLUSIONS AND RELEVANCE The HUI3 and SF-6D each provide unique information on different aspects of health status across the groups. The HUI3 better captures preterm-related changes to HRQoL in adulthood compared to SF-6D. Studies focused on measuring physical or cognitive aspects of health will likely benefit from using the HUI3 instead of the SF-6D, regardless of gestational age at birth and birthweight status.

Abstract
El incremento observado en las tasas de suicidio en jóvenes hace necesario contar con escalas de cribaje para la identificación de personas en riesgo. La escala de ideación suicida de Roberts (EIS) es un instrumento breve que ha mostrado propiedades psicométricas adecuadas en adolescentes mexicanos. El objetivo del presente estudio fue corroborar la estructura de dicho instrumento mediante un análisis factorial confirmatorio (AFC) y analizar sus propiedades psicométricas en estudiantes universitarios. Aplicando un método cuantitativo instrumental, se administró la EIS a 1190 universitarios. Los resultados del AFC corroboran la estructura unifactorial de la EIS; asimismo, la consistencia interna, reportada con el alfa de Cronbach ordinal (αO = 0.813), resultó adecuada. Se concluye que el instrumento muestra una estructura unifactorial y que las características psicométricas de los reactivos fueron adecuadas, resalta que 2.9 % de la muestra obtuvo una puntuación que indica alto riesgo suicida.

Abstract
Psychopathology is defined in part by its impacts on life functioning (e.g., fulfillment of daily responsibilities at work or school, in family relationships). Relations to life functioning are particularly important in the validation of culture-specific syndromes (patterns of mental health symptoms specific to a particular culture), to demonstrate that culture-specific symptom patterns do in fact represent pathology. The current study's goal was to assess the construct validity of the Cambodian Somatic Symptom and Syndrome Inventory (CSSI). The study focused on the statistically unique effects of the CSSI on life functioning (i.e., effects of the CSSI on life functioning, controlling for Western psychopathology syndromes), to determine whether the CSSI contributes information beyond standard Western measures, which would support CSSI culture-specific convergent validity. Because adolescence is a key period when psychopathology often develops, study participants were 391 high-school students in one urban and one rural area of Cambodia. Participants completed the CSSI, the Western psychopathology surveys Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder questionnaire (GAD-7), and life functioning measures assessing functional impairment, quality of life, and help-seeking. Results indicated strong CSSI concurrent validity (canonical correlation = 0.75) with the PHQ-9 and GAD-7, and CSSI total effects convergent validity on life functioning indicators. All CSSI statistically unique effects (controlling for the PHQ-9 and GAD-7) on life functioning measures were non-significant indicating that the CSSI, shown to be a valid assessment measure in the current study, does not add predictive information beyond standard Western measures. A key limitation that should be considered in interpretation of these results is that the life functioning measures, although reviewed by Khmer psychologists, were Western-based, thus potentially inflating relations with Western psychopathology measures.

Abstract
Aim Few studies have investigated the health-related quality of life (HRQoL) in long-stay inpatients with chronic schizophrenia in Japan. This study aimed to clarify the factors associated with HRQoL among these patients. Methods Out of 238 patients with chronic schizophrenia admitted to three hospitals, 101 inpatients provided informed consent to participate in the study. The patients' HRQoL was assessed using two instruments: the EuroQol 5 dimensions (EQ-5D) as a generic index and the Subjective Well-being Under Neuroleptic Treatment Scale, Japanese Version (SWNS-J) as a disease-specific index. We examined the factors associated with these HRQoL indices using multiple linear regression models. Results The patients' mean age was 62.9 years, and 51.5% were female. The mean (standard deviation) EQ-5D score and SWNS-J total score were 0.776 (0.177) and 83.5 (16.5), respectively. Multiple linear regression analysis indicated that the EQ-5D score was significantly and negatively associated with the female sex, benzodiazepine use, and Drug-Induced Extrapyramidal Symptoms Scale scores. In contrast, the SWNS-J total score was significantly and negatively associated with first-generation antipsychotics use, Brief Psychiatric Rating Scale scores, Drug-Induced Extrapyramidal Symptoms Scale scores, and Global Assessment of Functioning scale scores. Conclusion This study identified the factors associated with two HRQoL indices among long-stay inpatients with chronic schizophrenia in Japan. Although the analyses showed differences in the associated factors between the generic EQ-5D and the disease-specific SWNS-J, extrapyramidal symptoms as adverse effects of antipsychotic treatment were found to be associated with both indices.

Abstract
INTRODUCTION EQ-5D is an instrument which has been utilized for a variety of purposes, including in health-economic appraisals as an input into quality-adjusted life year (QALY) calculations. Indeed, it is the most-widely applied instrument for health-economic appraisal worldwide, and is recommended for use in QALY calculations by many national Health Technology Assessment (HTA) agencies. There is also a growing body of evidence for its usefulness in a variety of settings other than economic appraisals, but such use has not been well-documented. This study addresses this issue and documents how EQ-5D has been applied in both the non-economic and economic contexts. METHODS The PubMed database was searched using the terms 'EQ-5D', 'EQ-5D AND cost', and 'EQ-5D AND cost AND QALY' from 1 January 1980 to 31 December 2019. We concentrated on 2019 publications for more detailed analyses. All the data collected for 2019 were downloaded and collected in EndNote. For 2019 only, we classified economic and non-economic use based on the inclusion of 'cost'. We also checked by manual inspection whether the search terms were suitable in correctly identifying economic and non-economic use. Variants of the non-economic use of EQ-5D were classified as follows: (a) as a quality of life outcome measure; (b) as a tool for methodological research; (c) methodological issues of EQ-5D itself; (d) comparisons with other quality of life questionnaires; (e) mapping studies; (f) value sets; (g) alongside costs but no QALY calculated; and (h) other. RESULTS The first publication found was from 1990. Up to and including 2019, 10,817 publications were identified, of which more than two in three did not contain any reference to costs or QALYs. In 2019, a total of 1409 manuscripts were identified, of which 239 were specifically for EQ-5D-5L. Four hundred and seven (28.9%) included some form of 'costs' and 157 (11.1%) both 'costs' AND 'QALYs' terms. For EQ-5D-5L, the corresponding numbers were 104 (43.5%) and 29 (12.1%), respectively. After manually checking all the 1409 papers, three were duplicated records, which were omitted. In the remaining 1406 papers, only 40 (2.8%) contained the term 'cost', but not 'cost per QALY', and only 117 (8.3%) were identifiable as economic evaluations using the term 'cost per QALY'. Most non-economic use of EQ-5D was as a quality-of-life outcome measure (72.8%). Other applications were: as a tool for methodological research (6.7%); comparison studies (3.7%); EQ-5D methodological issues (3.5%); containing costs but not QALYs (2.8%); mapping (1.3%); value sets (0.4%); and other papers (0.4%). CONCLUSIONS The majority of the studies retrieved, covering a wide variety of research areas, reported upon the non-economic use of EQ-5D. Despite being the most-used instrument worldwide for QALY calculations, economic appraisal accounted for only a small, but important, part of published use.

Abstract
BACKGROUND SF-6Dv2, the latest version of SF-6D, has been developed recently, and its measurement properties remain to be evaluated and compared with the EQ-5D-5L. The aim of this study was to assess and compare the measurement properties of the SF-6Dv2 and the EQ-5D-5L in a large-sample health survey among the Chinese population. METHODS Data were obtained from the 2020 Health Service Survey in Tianjin, China. Respondents were randomly selected and invited to complete both the EQ-5D-5L and SF-6Dv2 through face-to-face interviews or self-administration. Health utility values were calculated by the Chinese value sets for the two measures. Ceiling and floor effects were firstly evaluated. Convergent validity and discriminate validity were examined using Spearman's rank correlation and effect sizes, respectively. The agreement was assessed using intraclass correlation coefficients (ICC). Sensitivity was compared using relative efficiency and receiver operating characteristic. RESULTS Among 19,177 respondents (49.3% male, mean age 55.2 years, ranged 18-102 years) included in this study, the mean utility was 0.939 (0.168) for EQ-5D-5L and 0.872 (0.184) for SF-6Dv2. A higher ceiling effect was observed in EQ-5D-5L than in SF-6Dv2 (72.8% vs. 36.1%). The Spearman's rank correlation (range: 0.30-0.69) indicated an acceptable convergent validity between the dimensions of EQ-5D-5L and SF-6Dv2. The SF-6Dv2 showed slightly better discriminative capacities than the EQ-5D-5L (ES: 0.126-2.675 vs. 0.061-2.256). The ICC between the EQ-5D-5L and SF-6Dv2 utility values of the total sample was 0.780 (p < 0.05). The SF-6Dv2 had 29.0-179.2% higher efficiency than the EQ-5D-5L at distinguishing between respondents with different external health indicators, while the EQ-5D-5L was found to be 8.2% more efficient at detecting differences in self-reported health status than the SF-6Dv2. CONCLUSIONS Both the SF-6Dv2 and EQ-5D-5L have been demonstrated to be comparably valid and sensitive when used in Chinese population health surveys. The two measures may not be interchangeable given the moderate ICC and the systematic difference in utility values between the SF-6Dv2 and EQ-5D-5L. Further research is warranted to compare the test-retest reliability and responsiveness.

Abstract
Purpose To examine the differences between patient-reports and proxy-reports by nurses of EQ-5D-5L responses among patients with schizophrenia. Methods This study was conducted in June–September 2019 in Duren Sawit Regional Public Hospital in Jakarta, Indonesia. The self-report data were obtained by interviewing the patients and the proxy-report data were obtained from the psychiatric nurses. The patients’ Positive and Negative Syndrome Scale (PANSS) scores were obtained from their medical records. The data were collected in two time points: (1) when the patients moved from the acute to the quiet rooms (first-test) and (2) when they were discharged from the hospital (second-test). The self and proxy report scores were analysed by the Wilcoxon matched-pairs signed-ranks test and their relationship with the PANSS scores using Spearman's rank correlation coefficient. Results There were 206 patients in the final sample. The majority are male (56.8%) with a mean age of 37.5 years (SD = 12.05). Significant differences between the two reports were found in three domains (i.e., self-care, usual activities, and pain/discomfort) in the first-test and two domains (i.e., usual activities and pain/discomfort) in the second-test. Concerning the relationship with the PANSS scores, only three significant correlations were found, all in the proxy-version and in the second-test: mobility (r = 0.139), anxiety/depression (r = 0.2523), and utility scores (r = − 0.176). Conclusions The poor-to-fair agreement between patients and nurses reports and the poor correlation with the PANSS scores suggested that it is difficult to decide which report best represents the patients’ health status.

Abstract
PURPOSE This cross-sectional study investigated distribution, sociodemographic correlates, and health outcomes in early versus late age of onset (AOO) of mood, anxiety, and alcohol use disorders in Singapore. METHODS The Composite International Diagnostic Interview established lifetime diagnoses of major depressive, bipolar, generalized anxiety, obsessive compulsive and alcohol use disorders in a representative sample of residents aged 18 years and over (n = 6126). The AOO of the individual and any mental disorders were classified into early and late onset using median values as cut-offs. Data included socio-demographic and health background, health utility score, and productivity losses. Multivariable logistic regression analysis was conducted to assess sociodemographic correlates of early versus late AOO of any mental disorder while linear regression analysis investigated the associations between AOO of individual disorders with health utility score and productivity loss. RESULTS Respondents' mean (SD) age was 45.6 (16.5) years, comprising 50.5% women and majority of Chinese ethnicity (75.8%). The median AOO for any of the five studied disorders was 21 years (IQR: 15-29). Lowest AOO was observed for obsessive compulsive disorder (Median: 14, IQR: 11-26). Those aged 35 years and over (versus 18-34) were less likely to have earlier AOO [35-49 years (OR: 0.287; 95% CI: 0.154-0.534); 50-64 years (OR:0.156; 95% CI: 0.068-0.361) and 65 and over (OR:0.112; 95% CI:0.027-0.461)], while Malay ethnicity (versus Chinese) (OR: 2.319; 95% CI: 1.384-3.885) and being never married (versus married) (OR: 2.731; 95% CI: 1.493-4.993) were more likely to have early AOO for any mental disorder. Sample with early (versus late) AOO had a lower health utility score (β = - 0.06,95% CI: - 0.08 to - 0.03) and higher number of days cut down on the type of work (β = 1.61,95% CI: 0.12-3.10) in those with any mental disorders. CONCLUSION This study showed that half of the adults with mood, anxiety or alcohol use disorders in Singapore experienced their illness onset by 21 years of age. Early AOO is associated with sociodemographic background and poor health outcomes. Prevention, early detection, and interventions to improve health outcomes in mental disorders should consider the sociodemographic profile and age at first onset of symptoms in the population.

Abstract
BACKGROUND The EQ-5D is one of the most recommended questionnaires for cost-effectiveness studies. AIMS To study the psychometric properties of the EQ-5D-5L in patients with major depression. METHODS This prospective observational study included 433 patients with major depression who completed the EQ-5D-5L and Patient Health Questionnaire-9 (PHQ-9) questionnaires at baseline, of whom 310 also did six months later. The structural validity was assessed by confirmatory factor analysis, the item functioning by item response analysis, and reliability by Cronbach's alpha. Convergent validity and known-groups validity was studied using the PHQ-9 and a general health question. To assess responsiveness effect sizes were calculated. RESULTS The results supported the unidimensionality and showed adequate item functioning, with somewhat age-related item differential functioning for the mobility dimension. Cronbach's alpha was 0.77. The EQ-5D-5L showed a high correlation with the PHQ-9 and general health. The more severe the depression level and the poorer the general health, the lower the EQ-5D-5L scores (p < 0.001). Responsiveness parameters showed moderate changes among "improved" patients. CONCLUSIONS These findings support the adequate psychometric properties of the EQ-5D-5L in patients with major depression. It could be very useful for clinicians and researchers as an outcome measure and for use in economic evaluation.

THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2020; 21:1039-1048. [PMID: 32419059 DOI: 10.1007/s10198-020-01196-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Accepted: 04/25/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVE Drug and/or alcohol dependence (DAD) generates substantial costs to society. One of the main consequences of DAD is its negative impact on health-related quality of life (HRQoL). The main objective of this study is to analyse the impact of using EQ-5D-5L, SF-6DSG (SF-6D using standard-gamble as the preference-eliciting method) and SF-6DPG (SF-6D using a paired-gamble method), to estimate the HRQoL burden, attributable to DAD, within the cost-of-illness framework. METHODS A convenience sample of 109 patients with a diagnosis of substance use disorder was recruited. SF-6D and EQ-5D-5L were administered and then the utility scores were computed. The impact of employing different instruments to estimate the HRQoL burden was assessed by comparing the utility scores of patients and general population after controlling for sex and age through regression analysis. The analysis was reproduced for two subgroups of severity. RESULTS All instruments detect that DAD significantly affects the HRQoL. However, the estimated impact changes, according to the instrument used, whose pattern varies by severity group. Nonetheless, regardless of severity, SF-6DPG always estimates a higher or equal DAD burden than the other instruments considered. These results are compatible with the presence of the floor effect in SF-6DSG, the ceiling effect in EQ-ED-5L, and a smaller presence of both biases in SF-6DPG. CONCLUSIONS The SF-6DPG instrument emerges as a good candidate to avoid under-estimating intangible costs within the cost-of-illness framework. However, further research is needed to assess the validity of our results in the context of other health problems.

Abstract
OBJECTIVES We performed a systematic review of health state utility values (HSUVs) obtained using the EQ-5D questionnaire for patients with hematologic malignancies. METHODS The following databases were searched up to September 2018: MEDLINE, EMBASE, The Cochrane Library, and the EQ-5D publications database on the EuroQol website. Additional references were extracted from reviewed articles. Only studies presenting EQ-Index results were incorporated. In view of the heterogeneity across the included publications, we limited ourselves to a narrative synthesis of original HSUVs found. RESULTS Fifty-nine studies (described in 63 articles) met the inclusion criteria. Data from 21 635 respondents provided 796 HSUV estimates for hematologic malignancy patients. EQ-Index scores ranged from -0.025 to 0.980. The most represented area was multiple myeloma (4 studies, 11 112 patients, and 249 HSUVs). In clinical areas such as chronic myeloid leukemia, acute myeloid leukemia, chronic lymphocytic leukemia, non-Hodgkin lymphoma, and mantle cell lymphoma, we described over 50 health utilities in each. In contrast, we identified only 13 HSUVs (based on 4 studies and the data of 166 patients) for Hodgkin lymphoma. Areas without EQ-5D-based health utilities comprised: polycythemia vera, primary myelofibrosis, essential thrombocythemia, mastocytosis, myeloid sarcoma, chronic myelomonocytic, eosinophilic leukemia, and neutrophilic leukemia. CONCLUSIONS There is a wide range of HSUVs available for hematologic cancer patients with different indications. The review provides a catalog of utility values for use in cost-effectiveness models for hematologic malignancies.

Abstract
The current study aims to evaluate the burden of disease in Singapore by estimating the quality-adjusted life years (QALYs) lost due to mental disorders and chronic physical conditions. The second Singapore Mental Health Study (SMHS-2016) was conducted in 2016 among 6126 respondents aged 18 years and above. The World Health Organization Composite International Diagnostic Interview version 3.0 (WHO-CIDI 3.0) and a modified version of the CIDI chronic medical disorders checklist were used to assess the 12-month diagnoses of mental and chronic physical disorders while the SF-6D scores derived from the 12-item Short Form Health Survey instrument was used to estimate the QALYs lost. The mean SF-6D score in this population was 0.87. The largest reduction in SF-6D scores among people with mental disorders was observed in Generalized Anxiety Disorder (GAD), followed by Major Depressive Disorder (MDD), alcohol abuse, bipolar disorder and Obsessive Compulsive Disorder (OCD) while the largest reduction in SF-6D score among people with chronic physical conditions was observed in ulcer, followed by lung disease, chronic pain and cardiovascular disease. At the population level, chronic pain was associated with the greatest QALY loss followed by MDD (14,204 and 6,889 respectively). Lung disease was associated with the smallest QALY loss (376). These findings highlight chronic pain, MDD, OCD, cardiovascular disease and GAD as the five leading contributors of QALYs lost in the general population which deserve prioritisation in public health prevention programmes.

Abstract
OBJECTIVES Our aim was to systematically review published evidence on the construct validity, test-retest reliability and responsiveness of generic preference-based measures (PBMs) used in East and South-East Asia. METHODS This systematic review was guided by the COSMIN guideline. A literature search on the MEDLINE, EMBASE, PsycINFO and PubMed databases up to August 2019 was conducted for measurement properties validation papers of the EuroQol-5 Dimensions (EQ-5D), Short Form-6 Dimensions (SF-6D), Health Utilities Index (HUI), Quality of Well-Being (QWB), 15-Dimensional (15D) and Assessment of Quality of Life (AQOL) in East and South-East Asian countries. Included papers were disaggregated into individual studies whose results and quality of design were rated separately. The population-specific measurement properties (construct validity, test-retest reliability and responsiveness) of each PBM were assessed separately using relevant studies. The overall methodological quality of the studies used in each of the assessments was also rated. RESULTS A total of 79 papers containing 1504 studies were included in this systematic review. The methodological quality was 'very good' or 'adequate' for the majority of the construct validity studies (99%) and responsiveness studies (61%), but for only a small portion of the test-retest reliability studies (23%). EQ-5D was most widely assessed and was found to have 'sufficient' construct validity and responsiveness in many populations, while the SF-6D and EuroQol-Visual Analog Scale (EQ-VAS) exhibited 'inconsistent' construct validity in some populations. Scarce evidence was available on HUI and QWB, but current evidence supported the use of HUI. CONCLUSIONS This systematic review provides a summary of the quality of existing generic PBMs in Asian populations. The current evidence supports the use of EQ-5D as the preferred choice when a generic PBM is needed, and continuous testing of all PBMs in the region.

Abstract
This study investigated the efficacy of 10-module metacognitive training (MCT) among Japanese patients with schizophrenia by conducting a multicenter randomized controlled trial to test the influence of the most recent and extended version of MCT on positive symptoms. A six-center, randomized, assessor-blind, controlled trial between "treatment as usual" (TAU) and TAU + MCT was conducted. Fifty inpatients and outpatients with schizophrenia, schizotypal, and delusional disorders (ICD 10) were enrolled, then randomly assigned to TAU (n = 26) or TAU + MCT (n = 24). Assessments were made at baseline, after six weeks, immediately posttreatment, and 1-month post-treatment. The primary outcome was positive symptom score, as measured by the Positive and Negative Syndrome Scale (PANSS). General assessment of functioning (GAF) and measures of cognitive biases were secondary outcomes. Completion at post-treatment (10 weeks later) and 1-month follow-up was high-TAU + MCT, n = 22 (91.67%) and TAU, n = 23 (88.46%). The severity of PANSS positive symptoms declined significantly in the TAU + MCT treatment group compared with the TAU group. GAF also showed significantly greater improvement in the TAU + MCT group compared with the TAU group. There was also a trend for greater efficacy of MCT on cognitive biases. In conclusion, this study provides support for the efficacy of 10 module MCT concerning positive symptomatology (especially, delusion) and general functioning.
