Summary of the paper
This study investigates the construct validity of the ICECAP-A capability measure, using face-to-face interviews with the UK general population. 418 participants were randomly selected from the Postcode Address File and were presented with the ICECAP-A measure and a series of contextual questions relating to socio-demographics, material well-being, major life events, happiness, religiosity, health, use of health care and perceptions of freedom. The authors developed hypotheses about the expected associations between individuals’ responses to the ICECAP-A measure and these contextual factors. Their hypotheses were investigated using statistical tests of association. ICECAP-A responses and scores reflected differences across different health and socio-economic groups, but did not distinguish individuals by the level of local deprivation. The authors found that mean ICECAP-A scores reflected individuals’ perceived freedom more closely than did measures of health and happiness. This study suggests that the ICECAP-A measure can identify expected differences in capability well-being in a general population sample.
- Are the authors’ pre-determined hypotheses appropriate and sufficient?
- Are the contextual factors defined such that they isolate capabilities from functioning?
- Is the scope of capability appropriately defined?
- To what extent could the ICECAP-A inform allocation decisions in health care?
