Objective: To develop a value set for the Short-Form 6-Dimension version 2 (SF-6Dv2) by incorporating societal preferences obtained from three distinct approaches: Standard Gamble (SG), composite Time Trade-Off (cTTO), and Discrete Choice Experiment (DCE).

Methods: Data were gathered from the general population of Quebec, Canada, using the standardized valuation protocol developed by EuroQol for the cTTO and DCE tasks, as well as the valuation protocol developed by Sheffield University for the SG. The SG and cTTO data were analyzed using OLS, GLS, GLS Tobit, and heteroskedastic Tobit models.

Severe burn injuries (SBIs) are known to pose a significant burden on patients, caregivers, and the healthcare system. Yet, scarce data on the short and long-term clinical and economic impacts of these injuries limit the development of evidence-informed strategies and policies to better care for these patients. To fill in this gap, we adapted a previously validated self-reported out-of-pocket cost measurement questionnaire, the Cost for Patients Questionnaire (CoPaQ), to the severe burn injury survivor context.

Quality of life at work is an important and widely discussed concept in the literature. Several instruments can be used to measure it, but with regard to healthcare and social services, the existing instruments are not well known. A review of available instruments intending to capture the quality of life of healthcare and social services workers (QoLHSSW) is necessary to better assess their working conditions and promote programs/guidelines to improve these conditions.

A considerable debate persists in the literature about whose preferences should be considered in the calculation of quality-adjusted life-years. Some suggest considering only the preferences of the general population, while others advocate for the consideration of those of patients or a combination of both. This study aims to inform and measure the differences in health preferences between cancer patients and the general population in Quebec.

Background: Because health resources are limited, health programs should be compared to allow the most efficient ones to emerge. To that aim, health utility instruments have been developed to allow the calculation of quality-adjusted life-year (QALY). However, generic instruments, which can be used by any individual regardless of their health profile, typically consider the preferences of the general population when developing their value set.

Background: Work-related stressors and work-family conflict are important social determinants of mental health. While the impact of these stressors on parents' mental health is well documented, we know comparatively less about their impact on children's mental health. Furthermore, though the COVID-19 pandemic has significantly altered these stressors, particularly with the increase in teleworking, major knowledge gaps persist regarding the association between parents' stressors and perceived parental concern for their children's mental health during the COVID-19 pandemic.

Background: Quality-adjusted life-year instruments help comparison among programs by capturing their effects in terms of utility. Generic instruments are applicable to everyone, and for this reason, they are known to lack sensitivity when measuring gains in some domains. Specific instruments tend to fill this gap but, in domains like cancer, existing instruments are either nonpreferences-based or based on the general population's preferences.
