单项自评的研究表现 一般来说，您认为自己的健康状况是：优秀、很好、良好、一般还是较差？使用同时患有慢性身体疾病的精神科门诊患者样本数据（N = 177），相对于包含该项目的 SF-36 一般健康量表进行评估。在横断面有效性测试和预测 2 年结果方面，该量表比单项更稳健，但单项作为身体健康指标具有更强的判别效度，尤其是在基线后分析中。单项和量表都足够敏感，可以检测两年内感知健康的变化，以及随机试验中对健康自我感知的条件实验效应。这些发现表明，对于纵向研究目的，全球单项目量表可以与多项目量表一样有效、可靠和敏感，即使该量表在横断面调查或作为筛选措施中表现更好。
The research performance of the single-item self-rating In general, would you say your health is: excellent, very good, good, fair, or poor? was evaluated relative to the SF-36 General Health Scale that contains this item, using data for a sample of psychiatric outpatients who had co-occurring chronic physical conditions (N = 177). The scale was more robust than the single-item in cross-sectional validity tests and for predicting 2-year outcomes, but the single-item had stronger discriminant validity as a measure of physical health, especially in post-baseline analyses. Single-item and scale were both sensitive enough to detect change in perceived health over 2 years and a conditional experimental effect on health self-perceptions in a randomized trial. These findings demonstrate that a global single-item can be as valid, reliable, and sensitive as a multi-item scale for longitudinal research purposes, even if the scale performs better in cross-sectional surveys or as a screening measure.
