      abstract     = {The EQ Health and Wellbeing (EQ-HWB) is a generic
                      instrument recently developed for use in economic
                      evaluations across public health and social care, including
                      impacts on caregivers. Providing informal care to a person
                      living with dementia can significantly affect the health and
                      well-being of carers. However, it is unclear to what extent
                      the EQ-HWB can capture such impacts. We aimed to investigate
                      the psychometric properties of the EQ-HWB compared with
                      other available instruments in caregivers of persons living
                      with dementia.An online survey included demographics,
                      informal care-related questions, and quality-of-life
                      measures suitable for caregivers (C-DEMQOL and CarerQol) and
                      the 25-item EQ-HWB. We used the UK pilot value set for the
                      index scores for the EQ-HWB-S (9-item short form). The
                      psychometric properties of the EQ-HWB and EQ-HWB-S were
                      assessed in terms of acceptability (missing data), response
                      distribution, known-groups validity analysis using t tests
                      and one-way ANOVAs (Cohen's d and Eta squared for effect
                      size), convergent validity (Spearman correlations), and an
                      exploration of dimensionality using exploratory factor
                      analysis.In known-group validity analysis, the EQ-HWB
                      instruments performed similarly to the C-DEMQOL in terms of
                      effect sizes across a range of variables and slightly better
                      than the CarerQol on some variables. At the item level, 13
                      of the 25 items could discriminate respondents by caregiving
                      time and 23 of 25 items by caregivers' general self-reported
                      health. Most hypothesized correlations in the convergent
                      validity analysis were found to be above 0.3.Our results
                      suggest that the EQ-HWB instruments performed well in this
                      population.},
