To crosswalk the National Institutes of Health (NIH) Pain Consortium's Research Task Force proposed Impact Stratification Score (ISS) to the PEG (Pain Intensity, Interference With Enjoyment of Life, Interference With General Activity) Scale.
Cross-sectional data collected in 2021. Ordinary least squares regression analyses of ISS and PEG.
Amazon Mechanical Turk workers.
1931 adults with back pain with an average age of 41 (range, 19-77); 48% were female, 16% Hispanic, 7% non-Hispanic Black, 5% non-Hispanic Asian, and 71% non-Hispanic White (N=1931).
Not applicable.
The Patient-Reported Outcomes Measurement Information System (PROMIS)-29+2 v2.1 survey that includes the ISS, and the 3-item PEG.
The ISS and PEG had a correlation coefficient of 0.74. The ISS accounted for 55% of the adjusted variance in the PEG and the standardized average deviation between observed and predicted scores (normalized mean absolute error) was 0.53. Likewise, the PEG explained 55% of the variance in the ISS with a normalized mean absolute error of 0.52.
This study provides a crosswalk between the ISS and PEG that can be used to predict one from the other. The regression equations can facilitate comparisons in studies that use different measures.
将美国国立卫生研究院（NIH）疼痛联合会研究工作组提出的影响分层评分（ISS）转换为 PEG（疼痛强度、对生活享受的干扰、对一般活动的干扰）量表。
2021 年收集的横断面数据。ISS 和 PEG 的普通最小二乘回归分析。
亚马逊土耳其机器人工人。
1931 名背痛成年人，平均年龄 41 岁（范围 19-77 岁）；48%为女性，16%为西班牙裔，7%为非西班牙裔黑人，5%为非西班牙裔亚裔，71%为非西班牙裔白人（N=1931）。
不适用。
包括 ISS 和 3 项 PEG 的患者报告结局测量信息系统（PROMIS）-29+2 v2.1 调查。
ISS 和 PEG 的相关系数为 0.74。ISS 解释了 PEG 调整后方差的 55%，观察得分与预测得分之间的标准化平均偏差（归一化平均绝对误差）为 0.53。同样，PEG 解释了 ISS 方差的 55%，归一化平均绝对误差为 0.52。
本研究提供了 ISS 和 PEG 之间的转换，可以用来预测另一个。回归方程可以促进使用不同测量方法的研究中的比较。
