HUI2- Health Utilities Index
Generic
Measure domains: Sensation; ambulation/mobility; emotion; cognition; self-care; pain; fertility
Summary of development: The HUI2 and HUI3 are based on the HUI1, which was used as a health-utility measure for low-birthweight babies in the NICU. Originally developed for children with cancer, the HUI2 is a generic measure utilizing preference-based health states to evaluate quality-adjusted life years (QALYs) of clinical interventions (Torrance 1996). Based on literature searches, previous measures, and interviews with parents, the health domains deemed most desirable were: (1) sensory and communication ability, (2) happiness, (3) self-care, (4) pain or discomfort, (5) learning and school ability, and (6) physical activity ability (Cadman 1986). The seventh attribute of fertility was added based on long-term outcomes for children with cancer.
Parents of children with cancer and parents of a general population of children were interviewed using Standard Gamble and VAS health state rating (Torrance 1996). When answering, they were asked to imagine multiple health states from age 10 to age 70 to determine the most desirable conditions.
When revising the HUI2 to make the HUI3, the domain of Self-care was replaced by Dexterity which reflects inability to take care of oneself if incapacitated; Sensation was replaced by three domains: Vision, Hearing, and Speech, and the domain of Fertility was eliminated.
HUI questionnaires are available in many languages, in self- and proxy- assessment versions, in self- and interviewer-administered formats, and with various recall assessment periods. (Horsman 2003).
It is important to note that health utility scales that are made in the econometric tradition, such as the HUI Mark 2 and Mark 3, do not necessarily need psychometric testing such as internal consistency or structural validity. For these measures, other types of validity such as known groups validity and convergent validity may be useful.
