Abstract
PURPOSE To investigate the health-related quality of life (HRQoL) and subjective well-being (SWB) of children aged 9-12 years in eastern China, and examine concordance within child self-reported and parent proxy-assessed. METHODS Data was collected from 9 to 12 years old children (including their parents) in Shandong Province in 2018. Participants self-completed a hard-copy questionnaire including Child Health Utility 9D (CHU9D), Pediatric Quality of Life Inventory (PedsQL)™ 4.0 Short Form 15 Generic Core Scales (hereafter the PedsQL™), Student's Life Satisfaction Scale (SLSS), as well as information on socio-demographic characteristics and self-report health status. Spearman's correlation coefficients and the difference between sub-groups were conducted to assess and compare the agreement on HRQoL and SWB instruments. Exploratory factor analysis (EFA) was used to ascertain the number of unique underlying latent factors that were associated with the items covered by the two generic HRQoL and the SWB instruments. The concordance of child self-reported and parent proxy-assessed was analyzed using weighted kappa coefficient and Bland-Altman plots. RESULTS A total of 810 children and 810 parents were invited to participate in the survey. A valid sample of 799 (98.6%) children and 643 (79.4%) parents completed the questionnaire. The child self-reported mean scores were CHU9D = 0.87, PedsQL™ = 83.47, and SLSS = 30.90, respectively. The parent proxy-assessed mean scores were PedsQL™ = 68.61 and SLSS = 31.23, respectively. The child self-reported PedsQL™ was moderately correlated with the CHU9D (r = 0.52). There was a weak correlation between CHU9D and SLSS (r = 0.27). The EFA result found 3 factors whilst seven SLSS items grouped into a standalone factor (factor 3), and the nine dimensions of CHU9D shared two common factors with the PedsQL™ (factor 1 and factor 2). A low level of concordance was observed across all comparisons and in all domains (weighted kappa < 0.20) between parents and their children. Furthermore, a high level of discordance was observed between child self-reported and father proxy-assessed. CONCLUSIONS CHU9D and PedsQL™ instruments have a higher agreement in measuring the HRQoL in children. CHU9D/PedsQL™ and SLSS instruments showed a low agreement and EFA result suggested that measuring SWB in children potentially may provide further information, which might be overlooked by using HRQoL instruments exclusively. Concordance of child self-reported and parent proxy-assessed was poor. Overall, mother-child concordance was higher than father-child concordance.

Abstract
AIM The study aims to establish the first set of normative data for OxCAP-MH capability instrument and to examine its association with sociodemographic and anxiety/depression severity variables. METHODS A large-sample cross-sectional online survey was conducted among the Hungarian adult general population in 2021. OxCAP-MH standardized mean scores were compared across age, sex, education level, residence, employment, and marital status. Linear regression analysis was employed to determine the impact of sociodemographic and anxiety/depression severity on the OxCAP-MH score. RESULTS In total, N = 2000 individuals completed the survey. The sample mean age was 47.1, with female majority (53.4%). Most respondents had completed primary education (51%), were active on labour market (52.4%), lived in larger cities (70.0%), and were married/in relationship (61.1%). Nearly half of the participants reported experiencing depression (48.5%), anxiety (44.3%), and 38.6% reported having both. The mean OxCAP-MH score for the total sample was 67.2 (SD = 14.4), the highest in the non-depressed (74.4) and non-anxious (73.6) subgroups, the lowest among those with extremely severe depression (45.0) and severe anxiety (47.7). Regression results indicated that older individuals (by β = 0.1), males (β = 2.3), those with secondary or higher education (β = 2.7 and 4.5) and students (β = 6.8) had significantly (p<0.01) higher mental capabilities. Respondents with mild, moderate, severe, or extremely severe depression (β = -6.6, -9.6, -13.8, -18.3) and those with mild, moderate, or severe anxiety (β = -4.1, -7.7, -10.3) had lower capability scores. CONCLUSION The OxCAP-MH instrument effectively differentiated capabilities across sociodemographic groups and highlighting the impact of depression and anxiety severity on general population's mental capability.

Abstract
BACKGROUND Forcibly displaced populations are highly vulnerable to psychosocial distress and mental disorders, including alcohol misuse. In an ongoing trial that seeks to develop a transdiagnostic intervention addressing psychological distress and alcohol use disorders among conflict-affected populations, we will carry out a cost-effectiveness evaluation using a capability-based Oxford Capabilities Mental Health (OxCAP-MH) measure. The OxCAP-MH is a 16-item questionnaire developed from the Capability Approach, that covers multiple domains of functioning and welfare. The aim of the current paper is to present the results of the translation, cultural adaptation and valuation of the OxCAP-MH into Juba Arabic for South Sudanese refugees living in Uganda. We adhered to the official Translation and Linguistic Validation process of the OxCAP-MH. To carry out the translation, the Concept Elaboration document, official English version of the OxCAP-MH, and the Back-Translation Review Template were used. Four independent translators were used for forward and back translations. The reconciled translated version was then piloted in two focus group discussions (N = 16) in Rhino refugee settlement. A most important to least important valuation of the sixteen capability domains covered in the OxCAP-MH was also done. RESULTS The Juba Arabic version of the OxCAP-MH was finalized following a systematic iterative process. The content of the Juba Arabic version remained unchanged, but key concepts were adapted to ensure cultural acceptability, feasibility, and comprehension of the measure in the local context of Rhino refugee settlement. Most participants had low levels of literacy and required support with filling in the tool. Participants suggested an additional capability that is currently not reflected in the OxCAP-MH, namely access to food. Furthermore, discussions around the valuation exercise of the sixteen domains led to two separate importance scales, which showed relevant differences. CONCLUSIONS In this context, the OxCAP-MH was considered culturally acceptable. The valuation exercise proved cognitively demanding. Participants voiced confusion over how to answer the questions on the OxCAP-MH instrument due to low levels of literacy. These concerns invite consideration for future research to consider how measures such as the OxCAP-MH can be made more accessible to individuals with low literacy rates in resource poor settings.

Abstract
PURPOSE This study aimed to explore the health-related quality of life (HRQoL) and subjective wellbeing (SWB) of infertility patients in mainland China and to investigate the relationships between HRQoL and SWB instruments in infertility patients. METHODS We conducted this cross-sectional study in the Hospital for Reproductive Medicine Affiliated of Shandong University between April 2019 and November 2019. Participants self-completed the five-level EQ-5D (EQ-5D-5L) questionnaire, the Assessment of Quality of Life (AQoL)-8D, and the WHO-5 wellbeing index (WHO-5). The agreements between EQ-5D-5L and AQoL-8D were assessed employing intraclass correlation coefficient (ICC) and Bland-Altman plots. Exploratory factor analysis (EFA) was conducted to examine the difference in descriptive systems among the three instruments. RESULTS We analyzed a valid sample of 618 infertility patients (84.4%). The mean scores of the total EQ-5D-5L, AQoL-8D, and WHO-5 were 0.96 (95%CI 0.96, 0.96), 0.80 (95%CI 0.79, 0.81), and 16.92 (95%CI 16.52, 17.31), respectively. Patients diagnosed with primary infertility had significantly lower HRQoL and SWB than those with secondary infertility. The ICC of EQ-5D-5L and AQoL-8D was 0.14. The AQoL-8D (r = 0.625) was more strongly correlated with WHO-5 than with the EQ-5D-5L (r = 0.262). The EFA results indicated that HRQoL instruments and the WHO-5 instruments were complementary rather than substitutable. CONCLUSIONS Poorer HRQoL and SWB were found that primary than secondary infertility patients. There exists a poor agreement between EQ-5D-5L and AQoL-8D and the difference in the psychosocial components may explain the difference. Measuring both HRQoL and SWB could provide complementary information for infertility patients.

The Achieved Capabilities Questionnaire for Community Mental Health (ACQ-CMH): A consumer-based measure for the evaluation of community mental health interventions. AMERICAN JOURNAL OF COMMUNITY PSYCHOLOGY 2022; 70:327-339. [PMID: 35499287 PMCID: PMC10083923 DOI: 10.1002/ajcp.12599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 02/19/2022] [Indexed: 06/14/2023]
Abstract
The capabilities approach offers a multidimensional, ecological, and agent-centered framework that may inspire models of intervention and evaluation. A growing number of measures grounded on the capabilities approach for outcome measurement are appearing. Regarding community mental health, new consumer-valued measures-constructed in collaboration with consumers-are here considered crucial for a transformative shift. Meanwhile, new measurements need to provide psychometric evidence to enable proper choice and application. The Achieved Capabilities Questionnaire for Community Mental Health (ACQ-CMH) was developed in collaboration with consumers of community mental health services. It aims to assess consumers' capabilities achieved through program support. The present paper shows advancements in the measure validation through a confirmatory factor analysis within a sample of community mental health consumers (N = 225). Reliability and construct-related validity were also observed. A structural solution composed of five factors and 43 items revealed a better model fit than that obtained in a previous exploratory study. Findings support the reliability, sensibility, and both convergent and discriminant validity of using the ACQ-CMH in the evaluation of community mental health interventions. The ACQ-CMH offers a consumer-valued framework with specific dimensions and indicators of capabilities for use in a routine service evaluation setting.

Abstract
AbstractNeuroinflammation has been proposed to impact symptomatology in patients with schizophrenia spectrum disorders. While previous studies have shown equivocal effects of treatments with add-on anti-inflammatory drugs such as Aspirin, N-acetylcysteine and Celecoxib, none have used a subset of prospectively recruited patients exhibiting an inflammatory profile. The aim of the study is to evaluate the efficacy and safety as well as the cost-effectiveness of a treatment with 400 mg Celecoxib added to an ongoing antipsychotic treatment in patients with schizophrenia spectrum disorders exhibiting an inflammatory profile. The “Add-on Celecoxib treatment in patients with schizophrenia spectrum disorders and inflammatory cytokine profile trial (TargetFlame)” is a multicentre randomized, placebo-controlled phase III investigator-initiated clinical trial with the following two arms: patients exhibiting an inflammatory profile receiving either add-on Celecoxib 400 mg/day or add-on placebo. A total of 199 patients will be assessed for eligibility by measuring blood levels of three pro-inflammatory cytokines, and 109 patients with an inflammatory profile, i.e. inflamed, will be randomized, treated for 8 weeks and followed-up for additional four months. The primary endpoint will be changes in symptom severity as assessed by total Positive and Negative Syndrome Scale (PANSS) score changes from baseline to week 8. Secondary endpoints include various other measures of psychopathology and safety. Additional health economic analyses will be performed. TargetFlame is the first study aimed at evaluating the efficacy, safety and cost-effectiveness of the antiphlogistic agent Celecoxib in a subset of patients with schizophrenia spectrum disorders exhibiting an inflammatory profile. With TargetFlame, we intended to investigate a novel precision medicine approach towards anti-inflammatory antipsychotic treatment augmentation using drug repurposing.

Abstract
The Austrian government imposed multiple major lockdowns during the COVID-19 pandemic, but the relevant measures and their perceptions varied over time. The aim of this study was to compare the over-time impacts of the three COVID-19 lockdowns between March 2020 and December 2021 for (capability) wellbeing and mental health in Austria. Adult Austrian residents (n = 87) completed an online survey about their experiences during three COVID-19 lockdowns, including capabilities (OxCAP-MH), depression and anxiety (HADS), and general wellbeing (WHO-5). Differences across the baseline and follow-up scores of these instruments were summarised by demographic/socioeconomic characteristics. Longitudinal comparisons of the impacts of the lockdowns were conducted using random effect models on panel data for overall instrument scores and individual capability items. The levels of (capability) wellbeing and mental health decreased for most respondents across the three lockdowns: average 2.4% reduction in OxCAP-MH scores, 18.8% and 9% increases in HADS depression and anxiety subscale scores respectively, and 19.7% reduction in WHO-5 score between the first and third lockdowns. Mental health treatment prior to the pandemic, social support and satisfaction with government measures were the most influential characteristics that determine the association with impacts of the chain of lockdowns. Our study is the first to assess the differential capability limiting aspects of lockdowns over time alongside their impacts on mental health and general wellbeing and calls for special attention for mental health patients, isolation and satisfaction with government measures.

Abstract
BACKGROUND There is increasing evidence that assessing outcomes in terms of capability provides information beyond that of health-related quality of life (HRQoL) for outcome evaluation in mental health research and clinical practice. AIMS To assess similarities and differences in the measurement properties of the ICECAP-A capability measure and Oxford Capabilities Questionnaire for Mental Health (OxCAP-MH) in people with schizophrenia experiencing depression, and compare these measurement properties with those of (a) the EuroQol EQ-5D-5L and EuroQol Visual Analogue Scale (EQ-VAS) and (b) mental health-specific (disease-specific) measures. METHOD Using data for 100 patients from the UK, measurement properties were compared using correlation analyses, Bland-Altman plots and exploratory factor analysis. Responsiveness was assessed by defining groups who worsened, improved or remained unchanged, based on whether there was a clinically meaningful change in the instrument scores between baseline and 9-month follow-up assessments. RESULTS The two capability instruments had stronger convergent validity with each other (Spearman's rho = 0.677) than with the HRQoL (rho = 0.354-0.431) or the mental health-specific (rho = 0.481-0.718) instruments. The OxCAP-MH tended to have stronger correlations with mental health-specific instruments than the ICECAP-A, whereas the ICECAP-A had slightly stronger correlation with the EQ-VAS. Change scores on the capability instruments correlated weakly with change scores on the HRQoL scales (rho = 0.131-0.269), but moderately with those on mental health-specific instruments for the ICECAP-A (rho = 0.355-0.451) and moderately/strongly on the OxCAP-MH (rho = 0.437-0.557). CONCLUSIONS Assessing outcomes in terms of capabilities for people with schizophrenia and depression provided more relevant, mental health-specific information than the EQ-5D-5L or the EQ-VAS. The ICECAP-A and the OxCAP-MH demonstrated similar psychometric properties, but the OxCAP-MH was more correlated with disease-specific instruments.

Abstract
BACKGROUND Some capability dimensions may be more important than others in determining someone's well-being, and these preferences might be dependent on ill-health experience. This study aimed to explore the relative preference weights of the 16 items of the German language version of the OxCAP-MH (Oxford Capability questionnaire-Mental Health) capability instrument and their differences across cohorts with alternative levels of mental ill-health experience. METHODS A Best-Worst-Scaling (BWS) survey was conducted in Austria among 1) psychiatric patients (direct mental ill-health experience), 2) (mental) healthcare experts (indirect mental ill-health experience), and 3) primary care patients with no mental ill-health experience. Relative importance scores for each item of the German OxCAP-MH instrument were calculated using Hierarchical Bayes estimation. Rank analysis and multivariable linear regression analysis with robust standard errors were used to explore the relative importance of the OxCAP-MH items across the three cohorts. RESULTS The study included 158 participants with complete cases and acceptable fit statistic. The relative importance scores for the full cohort ranged from 0.76 to 15.72. Findings of the BWS experiment indicated that the items Self-determination and Limitation in daily activities were regarded as the most important for all three cohorts. Freedom of expression was rated significantly less important by psychiatric patients than by the other two cohorts, while Having suitable accommodation appeared significantly less important by the expert cohort. There were no further significant differences in the relative preference weights of OxCAP-MH items between the cohorts or according to gender. CONCLUSIONS Our study indicates significant between-item but limited mental ill-health related heterogeneity in the relative preference weights of the different capability items within the OxCAP-MH. The findings support the future development of preference-based value sets elicited from the general population for comparative economic evaluation purposes.

Abstract
Background A link between mental health and freedom of choice has long been established, in fact, the loss of freedom of choice is one of the possible defining features of mental disorders. Freedom of choice has internal and external aspects explicitly identified within the capability approach, but received little explicit attention in capability instruments. This study aimed to develop a feasible and linguistically and culturally appropriate Hungarian version of the Oxford CAPabilities questionnaire—Mental Health (OxCAP-MH) for mental health outcome measurement. Methods Following forward and back translations, a reconciled Hungarian version of the OxCAP-MH was developed following professional consensus guidelines of the International Society for Pharmacoeconomics and Outcomes Research and the WHO. The wording of the questionnaire underwent cultural and linguistic validation through content analysis of cognitive debriefing interviews with 11 Hungarian speaking mental health patients in 2019. Results were compared with those from the development of the German version and the original English version with special focus on linguistic aspects.
Results Twenty-nine phrases were translated. There were linguistic differences in each question and answer options due to the high number of inflected, affixed words and word fragments that characterize the Hungarian language in general. Major linguistic differences were also revealed between the internal and external aspects of capability freedom of choices which appear much more explicit in the Hungarian than in the English or German languages. A re-analysis of the capability freedom of choice concepts in the existing language versions exposed the need for minor amendments also in the English version in order to allow the development of future culturally, linguistically and conceptually valid translations.
Conclusion The internal and external freedom of choice impacts of mental health conditions require different care/policy measures. Their explicit consideration is necessary for the conceptually harmonised operationalisation of the capability approach for (mental) health outcome measurement in diverse cultural and linguistic contexts.

Cultural and linguistic adaptation of the multi-dimensional OXCAP-MH for outcome measurement of mental health among people living with HIV/AIDS in Uganda: the Luganda version. J Patient Rep Outcomes 2021; 5:32. [PMID: 33826007 PMCID: PMC8026780 DOI: 10.1186/s41687-021-00306-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Accepted: 03/24/2021] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND It is rare to find HIV/AIDS care providers in sub-Saharan Africa routinely providing mental health services, yet 8-30% of the people living with HIV have depression. In an ongoing trial to assess integration of collaborative care of depression into routine HIV services in Uganda, we will assess quality of life using the standard EQ-5D-5L, and the capability-based OxCAP-MH which has never been adapted nor used in a low-income setting. We present the results of the translation and validation process for cultural and linguistic appropriateness of the OxCAP-MH tool for people living with HIV/AIDS and depression in Uganda. METHODS The translation process used the Concept Elaboration document, the source English version of OxCAP-MH, and the Back-Translation Review template as provided during the user registration process of the OxCAP-MH, and adhered to the Translation and Linguistic Validation process of the OxCAP-MH, which was developed following the international principles of good practice for translation as per the International Society for Pharmacoeconomics and Outcomes Research's standards. RESULTS The final official Luganda version of the OxCAP-MH was obtained following a systematic iterative process, and is equivalent to the English version in content, but key concepts were translated to ensure cultural acceptability, feasibility and comprehension by Luganda-speaking people. CONCLUSION The newly developed Luganda version of the OxCAP-MH can be used both as an alternative or as an addition to health-related quality of life patient-reported outcome measures in research about people living with HIV with comorbid depression, as well as more broadly for mental health research.

Abstract
BACKGROUND The capability approach by Amartya Sen and Martha Nussbaum has gained increasing attention in the field of public health. As it combines individual, social and structural factors and shifts the focus of attention from the actual behavior towards available options for health behaviors that people can actually choose from, it may help advance our understanding of complex health issues. OBJECTIVES The aim of this article is to identify and describe tools available to measure capabilities within the context of health, with a specific focus on capabilities for health-enhancing physical activity. METHOD We conducted a systematic literature review using 11 databases covering scientific journal articles published in English or German between the years 2000 and 2020 with a focus on capabilities for health or physical activity. RESULTS We found a total of 51 articles meeting our inclusion criteria. Four articles measured capabilities using qualitative methods, one combined qualitative and quantitative methods, while the rest used quantitative methods. We identified a total 11 different capability questionnaires, all showing moderate to good validity/reliability. Only one questionnaire and one interview-based tool specifically dealt with capabilities for health enhancing physical activity. CONCLUSION Although we were able to identify measurement tools for capabilities in health, this review has shown that there is no generic tool available for the measurement across all population- and age-groups, and tools focusing on physical activity are scarce. However, our results can be used as guide for future projects that aim at measuring capabilities.

Abstract
BACKGROUND Impacts of the Covid-19 pandemic and its public health measures go beyond physical and mental health and incorporate wider well-being impacts in terms of what people are free to do or be. We explored the impacts of the Covid-19 lockdown and relevant vulnerabilities on capability well-being, mental health and social support in Austria. METHODS Adult Austrian residents (n = 560) provided responses to a cross-sectional online survey about their experiences during Covid-19 lockdown (15 March-15 April 2020). Instruments measuring capabilities (OxCAP-MH), depression and anxiety (HADS), social support (MSPSS) and mental well-being (WHO-5) were used in association with six pre-defined vulnerabilities using multivariable linear regression. RESULTS 31% of the participants reported low mental well-being and only 30% of those with a history of mental health treatment received treatment during lockdown. Past mental health treatment had a significant negative effect across all outcome measures with an associated capability well-being score reduction of - 6.54 (95%CI, - 9.26, - 3.82). Direct Covid-19 experience and being 'at risk' due to age and/or physical health conditions were also associated with significant capability deprivations. When adjusted for vulnerabilities, significant capability reductions were observed in association with increased levels of depression (- 1.77) and anxiety (- 1.50), and significantly higher capability levels (+ 3.75) were associated with higher levels of social support. Compared to the cohort average, individual capability impacts varied between - 9% for those reporting past mental health treatment and + 5% for those reporting one score higher on the social support scale. CONCLUSIONS Our study is the first to assess the capability limiting aspects of lockdown and relevant vulnerabilities alongside their impacts on mental health and social support. The negative capability well-being, mental health and social support impacts of the Covid-19 lockdown were strongest for people with a history of mental health treatment. Future public health policies concerning lockdowns should pay special attention to improve social support levels in order to increase public resilience.

Cost and quality-of-life impacts of community treatment orders (CTOs) for patients with psychosis: economic evaluation of the OCTET trial. Soc Psychiatry Psychiatr Epidemiol 2021; 56:85-95. [PMID: 32719905 PMCID: PMC7847440 DOI: 10.1007/s00127-020-01919-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Accepted: 07/02/2020] [Indexed: 12/27/2022]
Abstract
PURPOSE Current RCT and meta-analyses have not found any effect of community treatment orders (CTOs) on hospital or social outcomes. Assumed positive impacts of CTOs on quality-of-life outcomes and reduced hospital costs are potentially in conflict with patient autonomy. Therefore, an analysis of the cost and quality-of-life consequences of CTOs was conducted within the OCTET trial. METHODS The economic evaluation was carried out comparing patients (n = 328) with psychosis discharged from involuntary hospitalisation either to treatment under a CTO (CTO group) or voluntary status via Section 17 leave (non-CTO group) from the health and social care and broader societal perspectives (including cost implication of informal family care and legal procedures). Differences in costs and outcomes defined as quality-adjusted life years (QALYs) based on the EQ-5D-3L or capability-weighted life years (CWLYs) based on the OxCAP-MH were assessed over 12 months (£, 2012/13 tariffs). RESULTS Mean total costs from the health and social care perspective [CTO: £35,595 (SD: £44,886); non-CTO: £36,003 (SD: £41,406)] were not statistically significantly different in any of the analyses or cost categories. Mental health hospitalisation costs contributed to more than 85% of annual health and social care costs. Informal care costs were significantly higher in the CTO group, in which there were also significantly more manager hearings and tribunals. No difference in health-related quality of life or capability wellbeing was found between the groups. CONCLUSION CTOs are unlikely to be cost-effective. No evidence supports the hypothesis that CTOs decrease hospitalisation costs or improve quality of life. Future decisions should consider impacts outside the healthcare sector such as higher informal care costs and legal procedure burden of CTOs.

Abstract
PURPOSE Given increasing interest in using the capability approach for health economic evaluations and a growing literature, this paper aims to synthesise current information about the characteristics of capability instruments and their application in health economic evaluations. METHODS A systematic literature review was conducted to assess studies that contained information on the development, psychometric properties and valuation of capability instruments, or their application in economic evaluations. RESULTS The review identified 98 studies and 14 instruments for inclusion. There is some evidence on the psychometric properties of most instruments. Most papers found moderate-to-high correlation between health and capability measures, ranging between 0.41 and 0.64. ASCOT, ICECAP-A, -O and -SCM instruments have published valuation sets, most frequently developed using best-worst scaling. Thirteen instruments were originally developed in English and one in Portuguese; however, some translations to other languages are available. Ten economic evaluations using capability instruments were identified. The presentation of results show a lack of consensus regarding the most appropriate way to use capability instruments in economic evaluations with discussion about capability-adjusted life years (CALYs), years of capability equivalence and the trade-off between maximisation of capability versus sufficient capability. CONCLUSION There has been increasing interest in applying the capability-based approach in health economic evaluations, but methodological and conceptual issues remain. There is still a need for direct comparison of the different capability instruments and for clear guidance on when and how they should be used in economic evaluations.
