A new utility index derived of the SF-36, the SF-6D, was recently developed and has been compared with other utility measures. The objective was to validate this index in the Spanish version of SF-36 with respect to the EQ-5D.
1,843 complete measures of the SF-36 and the EQ-5D from 1,283 patients who received a solid organ transplant were collected. SF-6D values were calculated using the model proposed by its creator and without tariff values (not weighted). EQ-5D values were calculated using Spanish visual analog scale tariff (VAS-t), the time-trade off tariff (TTO-t) and also without tariff values (not weighted). Spearman correlation coefficients were calculated between SF-6D and EQ-5D values.
Mean value (standard deviation) of SF-6D was 0.67 (0.15), of VAS-t, 0.69 (0.24) and of TTO-t, 0.70 (0.32). SF-6D values had moderate correlation with VAS-t (r = 0.734) and TTO-t (r = 0.731) (both p < 0.001). The not weighted SF-6D had a high correlation with the weighted version (r = 0.969, p < 0.001), and moderate with the VAS-t (r = 0.754), TTO-t (r = 0.750) and no weighted EQ-5D (r = 0.784) (p < 0.001).
The SF-6D index derived from the Spanish version of SF-36 seem to be a valid utility index to be used with the SF-36 databases from studies made in Spain.
一种源自SF-36的新效用指数SF-6D最近被开发出来，并已与其他效用测量方法进行了比较。目的是在SF-36西班牙语版本中相对于EQ-5D对该指数进行验证。
收集了1283例接受实体器官移植患者的1843份完整的SF-36和EQ-5D测量数据。使用其创建者提出的模型且不使用关税值（未加权）计算SF-6D值。使用西班牙视觉模拟量表关税值（VAS-t）、时间权衡关税值（TTO-t）且也不使用关税值（未加权）计算EQ-5D值。计算SF-6D与EQ-5D值之间的斯皮尔曼相关系数。
SF-6D的平均值（标准差）为0.67（0.15），VAS-t为0.69（0.24），TTO-t为0.70（0.32）。SF-6D值与VAS-t（r = 0.734）和TTO-t（r = 0.731）具有中等相关性（两者p < 0.001）。未加权的SF-6D与加权版本具有高度相关性（r = 0.969，p < 0.001），与VAS-t（r = 0.754）、TTO-t（r = 0.750）和未加权的EQ-5D（r = 0.784）具有中等相关性（p < 0.001）。
源自SF-36西班牙语版本的SF-6D指数似乎是一个有效的效用指数，可用于西班牙进行的研究中的SF-36数据库。
