摘要
目的 探讨用 SF- 36评价人群健康状态效用的方法。方法 在四川某城市按年龄、性别、职业分层抽取 70人 ,用配对比较法分析研究其对 SF- 36各领域及领域内各条目的心理偏好程度 ,并据此确定各领域及领域内各条目的权重值。结果 确定了所有 8个领域的权重值和除躯体活动功能领域以外的其余 7个领域内各条目的权重值。用加权法计算所得的领域得分值及合计分值与简单相加法所得结果相比 ,除社会功能领域外 ,均有显著性差异 ,但各领域得分值用两种方法计算所得结果从数据上看差异不大。结论 加权法所得效用值能更准确地反映人们对健康状态的心理偏好程度 ,但在计算领域得分值时给各条目赋予权重的意义是有限的。
Objective To explore the methods of utility assessment using the short form 36. Methods The authors selected 70 people stratified by age, sex, and occupation in a city in Sichuan province, and investigated the preference of the population on each domain or item by paired comparison with other domains or items. Based on the preference, the weights of the domains and items were calculated. Results The weights of all the 8 domains and the items within 7 domains except the first domain 'physical functions' were identified. The total score and the scores of the domains calculated by weighted adding method were significantly different from those calculated by simple adding method. However, only little variation of the scores of the domains between the two methods appeared. Conclusion Utility calculated by weighted adding method may reflect people's preference to the health states more accurately. However, the value is limited in using weighted adding method for calculating the scores of domains.
