The SG technique typically involves the following steps:
Participants are presented with a hypothetical scenario where they have a certain health condition. They are then given two options: a certain outcome (living with the health condition) and a gamble. The gamble has two possible outcomes: perfect health or death. The probability of achieving perfect health versus death is varied until the participant is indifferent between the certain outcome and the gamble. The probability at which indifference occurs is taken as the utility value of the health condition.
