The Performance of a Value Set for the EQ-5D Based on Experienced Health States in Patients with Inflammatory Bowel Disease

EHS-VAS renders experience-based valuations but not decision utilities. GHS-based approaches cover severe health states more extensively, but study patients reported health states similar to those of a general population. Compared to GHS time-trade off value sets, the EHS-VAS value set predicted EQ-5D VAS valuations by patients with inflammatory bowel disease equally well and partly better. It performed partly better with respect to test-retest reliability and the same with respect to construct validity.
