Valuing health for oneself versus one's child or elderly parent.

The aim of this study was to determine if adults value health states or are willing to accept risk differently for themselves than for their children or elderly parents. Participants (701) were asked to rate four hypothetical health states for themselves using both the standard gamble and time trade-off methodologies. They then did the same assessments for a real or hypothetical child as well as an elderly parent. Participants were willing to take more risk or trade more years of life to avoid bilateral vision loss and mental impairment for themselves than they were for their children and elderly parents.
