标准的赌博方法，目前推荐用于医疗保健计划的评估，提供了一个人的偏好得分或“效用权重”，生活在一个给定的健康状态，为个人的余生。许多研究人员将此值解释为与时间无关或“永恒”的值，并将健康状态按0（死亡）到1（完全健康）的比例进行排序，而不管健康状态的时间。本文探讨是否偏好评分的严重疼痛的健康状态是“永恒的”，或者换句话说，是否满足效用独立性假设。我们的研究结果表明，对于大多数受访者来说，偏好分数并不独立于时间。临床流行病学杂志52;11：1047-1053，1999年。(C)1999 Elsevier Science Inc.
The standard gamble method, as currently recommended for use in health care program evaluation, provides an individual's preference score or "utility weight" for living in a given health state for the rest of the individual's life. Many researchers interpret this value as a time-independent or "timeless" one and order health states on a scale of zero (death) to one (full health), regardless of the time spent in the health state. This article examines whether preference scores for a severe pain health state are "timeless," or in other words whether the utility independence assumption is satisfied. Our study results suggest that for the majority of respondents, the preference scores are not independent of time. J CLIN EPIDEMIOL 52;11:1047-1053, 1999. (C) 1999 Elsevier Science Inc.
