Cosmin reporting guideline for studies on measurement properties of patient‐reported outcome measures
Open AccessJoel Gagnier, Guilherme Tavares de Arruda et al.ARTICLEQuality of Life Research2025
Effect of present state bias on minimal important change estimates
Open AccessBerend Terluin, Piper Fromy et al.ARTICLEQuality of Life Research2024
We recommend the unconstrained LIRT- and LCFA-based MIC methods to estimate anchor-based MICs, irrespective of the degree of PSB. The APM-method is a feasible alternative if PSB is limited
Hypophosphatemia attenuates improvements in vitality after intravenous iron treatment in patients with inflammatory bowel disease
Open AccessJakob Bue Bjorner, N Kennedy et al.ARTICLEQuality of Life Research2024
Utility values improved significantly with intravenous iron treatment. Improvement in utility values was primarily driven by Vitality scores, which showed significantly greater improvement in the ferric derisomaltose arm. Smaller decreases in phosphate were associated with significantly higher Vitality scores, suggesting that quality of life improvement is attenuated by hypophosphatemia. The utility values can inform future cost-utility analysis
Valuation survey for SF-6Dv2 in Japan based on the international protocol
Open AccessTakeru Shiroiwa, Yosuke Yamamoto et al.ARTICLEQuality of Life Research2024
We obtained a value set for Japan (model 5). With the development of this value set, it is now possible to calculate quality-adjusted life years for economic evaluation in Japan when the SF-6Dv2 has been used
Estimating meaningful thresholds for multi-item questionnaires using item response theory
Open AccessBerend Terluin, Jaimy E Koopman et al.ARTICLEQuality of Life Research2023
The new IRT method perfectly recovers meaningful (interpretational) thresholds for multi-item questionnaires, provided that the data satisfy the assumptions for IRT analysis
Estimating anchor-based minimal important change using longitudinal confirmatory factor analysis
Open AccessBerend Terluin, Andrew Trigg et al.ARTICLEQuality of Life Research2023
Establishing thresholds for meaningful within-individual change using longitudinal item response theory
Open AccessJakob Bue Bjorner, Berend Terluin et al.ARTICLEQuality of Life Research2022
Results from traditional analyses of anchor-based MWIC are impacted by study conditions. LIRT constitutes a promising and more robust analytic approach to identifying thresholds for MWIC
Mediating role of multimorbidity in inequality in mortality
F Diderichsen, Anne Mette Bender et al.ARTICLEJournal of Epidemiology and…2022Referencias: 32
BACKGROUND: The social inequality in mortality is due to differential incidence of several disorders and injury types, as well as differential survival. The resulting clustering and possible interaction in disadvantaged groups of several disorders make multimorbidity a potentially important component in the health divide. This study decomposes the effect of education on mortality into a direct effect, a pure indirect effect mediated by multimorbi…
An item response theory analysis of an item pool for the recovering quality of life (ReQoL) measure
Open AccessAnju Keetharuth, Jakob Bue Bjorner et al.ARTICLEQuality of Life Research2020
The results from the IRT analyses confirm the robust structure properties and internal construct validity of the ReQoL instruments. The strong psychometric evidence generated guided item selection for the final versions of the ReQoL measures
Development in well-being and social function among Danish hemophilia patients with HIV
Open AccessEmilie B Ingvorsen, Christina Schnohr et al.ARTICLEBMC Public Health2019
Differences between Danish HIV + and HIV - PWH regarding well-being and psychosomatic symptoms seem to have evened out between 1988 and 2012. However, results suggest that HIV + PWH still experience stigmatization and lower levels of education
Effect of tardive dyskinesia on quality of life in patients with bipolar disorder, major depressive disorder, and schizophrenia
Open AccessJoseph P McEvoy, Joseph McEvoy et al.ARTICLEQuality of Life Research2019
The presence of TD is associated with worse HRQoL and social withdrawal. The most severe impact of TD is on physical aspects of patients' HRQoL
Applying PRO Reference Values to Communicate Clinically Relevant Information at the Point-of-care
Roxanne E Jensen, Jakob Bue BjornerARTICLEMedical Care2019Referencias: 19
INTRODUCTION: The inclusion of reference values for common patient-reported outcomes (PROs) measures in clinical care settings provides a clinically relevant context for an individual patient's PRO scores. PRO reference values are currently not reported in clinical care settings. This is a missed opportunity, as clinicians are familiar with the presence and interpretation of reference values, commonly provided alongside laboratory test results. I…
Health-related quality of life predicted subsequent health care resource utilization in patients with active cancer
Open AccessRegina Rendas‐Baum, Regina Rendas-Baum et al.ARTICLEQuality of Life Research2018
The significant associations between SF-12v2 scores from oncology patients and subsequent HCRU can guide interpretations of SF-12v2 scores in evaluation of therapies and in health policy decisions
Exploring the item sets of the Recovering Quality of Life (ReQoL) measures using factor analysis
Open AccessAnju Keetharuth, Jakob Bue Bjorner et al.ARTICLEQuality of Life Research2018
The analyses confirmed that the ReQoL item sets are sufficiently unidimensional to proceed to item response theory analysis. The model was robust across different ordering of positive and negative items
Worklife expectancy in a cohort of Danish employees aged 55–65 years - comparing a multi-state Cox proportional hazard approach with conventional multi-state life tables
Open AccessJacob Pedersen, Jakob Bue BjornerARTICLEBMC Public Health2017
WLE estimated through multi-state models provided an effective way to summarize complex data on labor market affiliation. WLE differed noticeably between members and non-members of the ERP scheme. It has been hypothesized that while ERP membership would prompt some employees to retire earlier than they would have done otherwise, this effect would be partly offset by reduced time spent on long-term sick leave or unemployment. Our data showed no in…
Conversion of standard retrospective patient-reported outcomes to momentary versions
Open AccessVictor Brun Boesen, Stine Birk Nissen et al.ARTICLEQuality of Life Research2017
Medically unexplained symptoms and the risk of loss of labor market participation - a prospective study in the Danish population
Open AccessKatja Loengaard, Jakob Bue Bjorner et al.ARTICLEBMC Public Health2015
MUS seem to have a negative effect on labor market participation defined by LTSA and unemployment, whereas it is more uncertain whether MUS affects risk of disability pensioning
Exploring the Experiences of People With Hypo- and Hyperthyroidism
Open AccessMette A Nexø, Torquil Watts et al.ARTICLEQualitative Health Research2015Citada por: 2Referencias: 28
Thyroid diseases evoke a complex range of psychological and physical symptoms. The psychosocial aspects of living with diseases causing hypo- or hyperthyroidism are poorly understood. In this article, we report the findings of a qualitative interview study in which we explored the lived experiences of 16 people with hypo- or hyperthyroidism. We purposefully selected participants from Danish outpatient clinics according to their diagnosis (Hashimo…
Influence of lifestyle factors on long-term sickness absence among female healthcare workers
Open AccessHelle Gram Quist, Birthe Lykke Thomsen et al.ARTICLEBMC Public Health2014
In female healthcare workers, an unhealthy lifestyle (too high/ too low body mass index, smoking, and low physical activity) is associated with higher risk of LTSA
Prediction of future labour market outcome in a cohort of long-term sick- listed Danes
Open AccessJacob Pedersen, Thomas Alexander Gerds et al.ARTICLEBMC Public Health2014
Only moderate prediction accuracy could be achieved using the selected information from the Danish register RSS. Other variables need to be included in order to establish a prediction method which provides more accurate risk profiles for long-term sick-listed persons
Thyroid-specific questions on work ability showed known-groups validity among Danes with thyroid diseases
Open AccessMette A Nexø, Torquil Watt et al.ARTICLEQuality of Life Research2014
Items on work limitations with attribution to thyroid disease were most effective in detecting impact on work ability and showed good predictive validity. Generic work ability items remain useful for general population comparisons
