背景：多项目健康状况测量可能是冗长的，昂贵的，繁重的收集。单项测量可能是一种替代方案。我们比较了两个单项的一般自测健康（GSRH）问题的测量特性，以评估它们在经过验证的多项工具中捕获信息的能力。方法：我们进行了一般健康调查（SF-12 V），其中包括“标准”和“比较”形式的GSRH。两周后，我们对相同的75名病情稳定的门诊患者重复了这项调查，以SF-12 V身体功能和情绪健康子量表作为参考，测试GSRH的重现性、可靠性和有效性。结果如下：在每次调查管理中，两个GSRH问题表现出良好的替代形式可靠性（第一次管理：r=0.74，p < 0.001;第二次管理：r=0.74，p < 0.001）和良好的再现性（“标准”：ICC 0.69;“比较”：ICC 0.85）。这两个GSRH项目与身体功能（“标准”：r=0.66;“比较”：r=0.56）和情绪健康措施（“标准”：r=0.65;“比较”：r=0.59）。与每个GSRH类别中的响应相关的平均子量表测量值显著不同（ANOVA，p < 0.001），表明强判别量表性能。结论：我们的单项，GSRH问题表现出良好的再现性，可靠性和强大的并发和判别尺度性能与既定的健康状况措施。
Background: Multi-item health status measures can be lengthy, expensive, and burdensome to collect. Single-item measures may be an alternative. We compared measurement properties of two single-item, general self-rated health (GSRH) questions to assess how well they captured information in a validated, multi-item instrument. Methods: We administered a general health survey (SF-12V) that included "standard" and "comparative" forms of a GSRH. We repeated the survey two weeks later to the same 75 medically stable outpatients to test for GSRH reproducibility, reliability, and validity using SF-12V Physical Functioning and Emotional Health subscales as a reference. Results: At each survey administration, the two GSRH questions demonstrated good alternate forms reliability (first administration: r=0.74, p < 0.001; second administration: r=0.74, p < 0.001) and good reproducibility ("standard": ICC 0.69; "comparative": ICC 0.85). Both GSRH items correlated with physical functioning ("standard": r=0.66; "comparative": r=0.56) and emotional health measures ("standard": r=0.65; "comparative": r=0.59). Mean subscale measures associated with responses in each GSRH category were significantly different (ANOVA, p < 0.001), indicating strong discriminant scale performance. Conclusions: Our single-item, GSRH questions demonstrated good reproducibility, reliability, and strong concurrent and discriminant scale performance with an established health status measure.
