We study item usage for a newly developed multidimensional CAT which draws items from three PROMIS domains, as well as a disease-specific one. Methods The multidimensional item bank used in the current study contained 194 items from four domains: the PROMIS domains ...

Measuring everyday functional competence using the Rasch assessment of everyday activity limitations (REAL) item bank

We describe the development and psychometric evaluation of a generic item bank for measuring everyday activity limitations in outpatient populations. Study design and setting Seventy-two items generated from patient interviews and mapped to the ...

Mapping of the DLQI scores to EQ-5D utility values using ordinal logistic regression

Purpose The Dermatology Life Quality Index (DLQI) and the European Quality of Life-5 Dimension (EQ-5D) are separate measures that may be used to gather health-related quality of life (HRQoL) information from patients. The EQ-5D is a generic measure from which health utility estimates can be derived, whereas the DLQI is a specialty-specific measure to assess HRQoL. To reduce the ...

Race-specific associations between health-related quality of life and cellular aging among adults in the United States: evidence from the National Health and Nutrition Examination Survey

Purpose Poor health-related quality of life (HRQOL) could lead to higher morbidity and mortality through telomere attrition or accelerated cellular aging. We conducted a cross-sectional analysis to examine the relationship between four dimensions of HRQOL and leukocyte telomere length (LTL) among a nationally representative sample of 3547 US adults (≥20 years) using the data from ...

Coping profiles and subjective well-being among people living with HIV: less intensive coping corresponds with better well-being

Purpose The aim of this study was to investigate the relationship between coping strategies and subjective well-being (SWB) among people living with HIV (PLWH) using the latent profile analysis (LPA) with control for socio-medical covariates. Methods The sample comprised five hundred and thirty people (N = 530) with a confirmed diagnosis of HIV+. The study was cross-sectional with ...

The impact of older person’s frailty on the care-related quality of life of their informal caregiver over time: results from the TOPICS-MDS project

Purpose To examine the impact of changes in an older person’s frailty on the care-related quality of life of their informal caregiver. Methods Five research projects in the TOPICS-MDS database with data of both older person and informal caregiver at baseline and after 12 months follow-up were selected. Frailty was measured in five health domains (functional limitations, ...

Use of large-scale HRQoL datasets to generate individualised predictions and inform patients about the likely benefit of surgery

Purpose The English NHS has mandated the routine collection of health-related quality of life (HRQoL) data before and after surgery, giving prospective patient information about the likely benefit of surgery. Yet, the information is difficult to access and interpret because it is not presented in a lay-friendly format and does not reflect patients’ individual circumstances. We set ...

The relationship between internalized stigma and quality of life among people with mental illness: are self-esteem and sense of coherence sequential mediators?

Purpose To elucidate the mechanism through which internalized stigma reduces the quality of life (QoL) of people with mental illness by exploring the mediating roles of self-esteem and sense of coherence (SOC). Methods A cross-sectional analysis of 229 patients diagnosed with schizophrenia or affective disorders was undertaken to test a sequential mediation model assuming that more ...

Methods and impact of engagement in research, from theory to practice and back again: early findings from the Patient-Centered Outcomes Research Institute

Purpose Since 2012, PCORI has been funding patient-centered comparative effectiveness research with a requirement for engaging patients and other stakeholders in the research, a requirement that is unique among the US funders of clinical research. This paper presents PCORI’s evaluation framework for assessing the short- and long-term impacts of engagement; describes engagement in ...

Measuring hemophilia caregiver burden: validation of the Hemophilia Caregiver Impact measure

Aims The purpose of this article is to describe the psychometric development of the Hemophilia Caregiver Impact measure. Methods Qualitative interviews (n = 22) and a cross-sectional web-based study (n = 458) were implemented with caregivers of people with hemophilia. Classical test theory and item response theory analyses were implemented to evaluate the psychometric ...

Clinical setting-based smoking cessation programme and the quality of life in people living with HIV in Austria and Germany

Purpose To report on the global quality of life (QOL) in people living with HIV (PLWHIV) and how a smoking cessation intervention influences the changes in QOL. Methods Participants were asked to fill out a questionnaire during visits to their HIV outpatient clinic consisting of sociodemographic information, general health data and the WHOQOL HIV-Bref. Exhaled carbon monoxide ...

Online support groups for head and neck cancer and health-related quality of life

Purpose To investigate the association between using online support groups (OSGs) and health-related quality of life (HRQoL), and the psychosocial factors that may influence this association among individuals with head and neck (H&N) cancer. Method A sample of 199 persons with H&N cancer using four OSGs completed an online questionnaire using six pre-validated measures for social ...

The impact of quality-of-life data in relative effectiveness assessments of new anti-cancer drugs in European countries

Purpose The aim of this study is to investigate the role of health-related quality-of-life (QoL) data in relative effectiveness assessments (REAs) of new anti-cancer drugs across European jurisdictions, during health technology assessment procedures. Methods Comparative analysis of guidelines and publicly available REAs in six European jurisdictions of anti-cancer drugs approved by ...

Risks associated with antiretroviral treatment for human immunodeficiency virus (HIV): qualitative analysis of social media data and health state utility valuation

Purpose Despite benefits of antiretroviral therapies (ART), people with HIV infection have increased risk of cardiovascular disease, kidney disease, and low bone mineral density. Some ARTs increase risk of these events. The purpose of this study was to examine patients’ perspectives of these risks and estimate health state utilities associated with these risks for use in ...
