cloudThe ICECAP-A (ICEpop CAPability measure for Adults) is a measure of capability for the general adult (18+) population for use in economic evaluation. 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 comprises five attributes (the lay terms 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)

The ICECAP-A descriptive system was developed using qualitative methods. A set of UK index values for ICECAP-A have been estimated using a best-worst scaling. Qualitative and quantitative studies of the validity of the ICECAP-A have been conducted with general population and patient samples.

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 on this website.
