The ICECAP-A (ICEpop CAPability measure for Adults) is a measure of capability for the general adult (18+) population for use in economic evaluation.
ICECAP-A comprises five conceptual attributes (the item description are in brackets):
- Attachment (an ability to have love, friendship and support)
- Stability (an ability to feel settled and secure)
- Achievement (an ability to achieve and progress in life)
- Enjoyment (an ability to experience enjoyment and pleasure)
- Autonomy (an ability to be independent)
Unlike most profile measures used in economic evaluations, the ICECAP-A focuses on wellbeing defined in a broader sense, rather than health. The measure covers attributes of wellbeing that were found to be important to adults in the UK. ICECAP-A is free to use, but the use of the measure must be registered with us first. More details on the registration, index values, validity and applications of the ICECAP-A can be found below.
Development and Validity
The ICECAP-A descriptive system was developed in the UK using in-depth interviews with adults (aged 18+) and constant comparative analysis to generate conceptual attributes, with further semi-structured interviews to generate meaningful wording . A set of UK index values for ICECAP-A have been estimated using a best-worst scaling approach, anchored on full capability and no capability. Qualitative and quantitative studies of the validity of the ICECAP-A have been conducted with both general population and patient samples
