“…This cross-cultural adaptation of the ICECAP-O indicates that the index has good test-retest reliability, similar to that observed in a Dutch study that focused on frail older adults [18]. On the other hand, the absolute agreement for each item was low to moderate in our study.…”

A Cross-Cultural Adaptation of the ICECAP-O: Test–Retest Reliability and Item Relevance in Swedish 70-Year-Olds

Background:While there is a plethora of Quality of Life (QoL) measures, the Investigating Choice Experiments for the Preferences of Older People-CAPability index (ICECAP-O) is one of the few that taps into the concept of capability, i.e., opportunities to 'do' and 'be' the things that one deems important in life. We aimed to examine test-retest reliability of the ICECAP-O in a Swedish context and to study item relevance. Methods: Thirty-nine 70-year-olds who took part in a population-based health study completed the Swedish version of the ICECAP-O on two occasions. We analyzed the test-retest reliability for the index and for the individual items. Participants also rated the relevance of each item on a visual analogue scale (0-100). Results: Test-retest reliability for the index score was in good agreement with an ICC of 0.80 (95% CI 0.62-0.90). However, Kappa was low for each item and ranged from 0.18 (control) to 0.41 (role). For attachment, we found a systematic disagreement with lower ratings at the second test occasion. Participants gave their highest relevance rating to attachment and lowest to enjoyment. Conclusion: The Swedish version of the ICECAP-O had good test-retest agreement, similar to that observed for the English version. Item level agreement was problematic, however, highlighting a need for future research.

“…This study represents a new application of the ICECAP-O instrument measuring broad aspects of quality of life in a sample of older people following a hip fracture for the first time previous studies having focused on community dwelling, transition care, or residential aged care populations [15, 28–30] [19, 34–37]. One previous study has reported ICECAP-O in a population following hip fracture with a mean score of 0.73 (SD 0.22) at four weeks following fracture among 59 people excluding those with cognitive impairment, higher than the value reported in our study.…”

“…Taking the most widely used of these instruments, the EQ-5D focuses upon five dimensions which are highly influenced by physical health and disability but which may not be sensitive to changes in other aspects of wellbeing and quality of life that are important to older people more broadly [13–15] and that are known to be reduced in addition to physical health domains following a hip fracture [16]. Therefore, investigation of instruments which measure quality of life more broadly in these social and emotional functioning domains is warranted in the hip fracture population.…”

“…However, participants with cognitive impairment were excluded from measurement of quality of life using the ICECAP-O, without use of a proxy. Other studies comparing the use of the EQ-5D-3 L and ICECAP-O in older adult populations have found the two instruments to be comparable in test-retest reliability, construct validity, and responsiveness in frail older adults [15, 19]. …”

BackgroundThe purpose of this study was to empirically compare the performance of two generic preference based quality of life instruments, EQ-5D-3 L (with a health and physical function focus) and ICECAP-O (with a wellbeing and capability focus), in a population of older Australians following hip fracture.MethodsOlder adults or their family member proxies (in cases of severe cognitive impairment) following surgery to repair a fractured hip were invited to take part in this cross sectional study. Inclusion criteria included an age of 60 years or older, confirmed falls-related hip fracture and those receiving current palliative care or consented to other research studies were excluded. 87 participants completed the ICECAP-O and EQ-5D-3 L instruments between one and three weeks post-surgery.ResultsFor the hip fracture population, the mean ICECAP-O score was 0.639 (SD 0.206, n = 82) and the mean EQ-5D-3 L utility score was 0.545 (SD 0.251, n = 87). There was a statistically significant positive correlation between the ICECAP-O and EQ-5D-3 L scores (r = 0.529, p = < 0.001).ConclusionsStudy findings indicate significant impairments in quality of life post hip fracture. In multiple regression analyses, age and health-related QoL (measured by the EQ-5D) were significant determinants of ICECAP-O scores, while proxy respondent status, age, and capability-related QoL (measured by the ICECAP-O) were significant determinants of EQ-5D scores. Approaches to measuring and valuing quality of life in this sample, should consider the target domains of the intervention in their choice of instrument. Studies aiming to measure the impact of interventions targeting broader domains of wellbeing and QoL should consider including a broader measure of QoL in conjunction with a HRQoL measure.

“…NICE technology appraisals avoid this given the stated preference for the use of the EQ-5D, at least in terms of adult conditions; there is less specificity around measuring HR-QoL for children, and the public health and social care guidance are even less prescriptive. The sensitivities of each measure to different patient groups and health or social conditions will become evident with time; there is already research being undertaken which is comparing the measures [38,60,61].…”

Choice of Outcome Measure in an Economic Evaluation: A Potential Role for the Capability Approach

The last decade has seen a renewed interest in Sen's capability approach; health economists have been instrumental in leading much of this work. One particular stream of research is the application of the approach to outcome measurement. To date, there have been a dozen attempts (some combined) to operationalise the approach, and produce an outcome measure that offers a broader evaluative space than health-related quality-of-life measures. Applications have so far been confined to public health, physical, mental health and social care interventions, but the capability approach could be of benefit to evaluations of pharmacotherapies and other technologies. This paper provides an introduction to the capability approach, reviews the measures that are available for use in an economic evaluation, including their current applications, and then concludes with a discussion of a number of issues that require further consideration before the approach is adopted more widely to inform resource allocation decisions.
