背景与目的：SF-36是评估和使用最广泛的生活质量问卷之一。从最初的8个维度发展出了两个概要组件（身体和精神）。本研究的目的是获得西班牙语权重，以计算SF-36和SF-12的汇总成分，评估其度量特征，并获得基于一般人群的参考规范。材料与方法：西班牙人口的代表性样本来自两项横断面研究：“药物消费家庭调查”（n = 9151）和“老年人动脉高血压及其他危险因素”（n = 3004）。分别采用主成分分析和多元线性回归计算SF-36和SF-12汇总成分的西班牙语权重。对已知组进行构念效度比较，用内部一致性系数评估信度。结果：获得的西班牙语权重与原始美国版本非常相似（相关系数> 0.9）。SF-12项解释了SF-36汇总成分91%的方差。老年人和大多数贫困群体的所有得分都较低（较差）（p < 0.001）。SF-36的内部一致性系数接近0.9，SF-12的内部一致性系数略低。结论：用西班牙权值估算的身心总结成分是可靠有效的。以西班牙普通人群为基础的这些摘要规范将有助于解释西班牙研究中SF系列问卷评估的生活质量结果。
BACKGROUND AND OBJECTIVE: The SF-36 is one of the most widely evaluated and used quality of life questionnaires. Two summary components (physical and mental) have been developed from its 8 original dimensions. The objective of this study was to obtain the Spanish weights to calculate the summary components of the SF-36 and the SF-12, to evaluate their metric characteristics, and to obtain general population based reference norms.MATERIAL AND METHOD: Representative samples of the Spanish population gathered from 2 cross-sectional studies: "Drug consumption home survey" (n = 9151) and "Arterial hypertension and other risk factors in the elderly" (n = 3,004). The Spanish weights of the summary components of SF-36 and SF-12 were calculated by principal component analysis and multiple linear regressions, respectively. Known groups were compared to evaluate construct validity and reliability was assessed with internal consistency coefficients.RESULTS: The Spanish weights obtained were very similar to those of the original American version (correlation > 0.9). The SF-12 items explained a 91% of the variance of SF-36 summary components. All the scores were lower (worse) in the elderly and most underprivileged groups (p < 0.001). Internal consistency coefficients were close to 0.9 for the SF-36, and slightly lower for the SF-12.CONCLUSIONS: Physical and mental summary components estimated with Spanish weights are reliable and valid. The Spanish general population based norms of these summaries will facilitate the interpretation of quality of life results assessed with the SF family of questionnaires in Spanish studies.
