Both the ICECAP-O and the ICECAP-A were reported to have good construct [49,51,52,64,66], convergent [29,53,55,58,60,62,67,70,71] validity when compared to the EQ-5D instrument to measure generic health status, and discriminant validity [29,55,58,67,71]. The ICECAP-O and ICECAP-A further showed good testretest reliability [29,43,57,62,77] and good internal consistency [29,51,58,70].…”
