作为妇女健康倡议研究的一部分，开发了5项妇女健康倡议影响力评定量表（WHIIRS）。本文通过使用66，269名绝经后妇女（平均年龄= 62.07岁，SD = 7.41岁）的反应总结了量表的开发。所有女性都完成了一份关于睡眠的10项问卷。作为数据分析的一部分，引入了一种新的重定位技术。对120，000个随机样本（每个样本1，000名妇女）进行了主轴因子分析，没有迭代和旋转方差最大解。使用这一战略导致发展的规模具有高度稳定的因素结构。结构方程模型显示，各年龄组和种族-民族组的因素结构无重大差异。详细描述了人种-种族和年龄亚组的WHIIRS标准。
As part of the Women's Health Initiative Study, the 5-item Women's Health Initiative Insomnia Rating Scale (WHIIRS) was developed. This article summarizes the development of the scale through the use of responses from 66,269 postmenopausal women (mean age = 62.07 years, SD = 7.41 years). All women completed a 10-item questionnaire concerning sleep. A novel resampling technique was introduced as part of the data analysis. Principal-axes factor analysis without iteration and rotation to a varimax solution was conducted for 120,000 random samples of 1,000 women each. Use of this strategy led to the development of a scale with a highly stable factor structure. Structural equation modeling revealed no major differences in factor structure across age and race-ethnic groups. WHIIRS norms for race-ethnicity and age subgroups are detailed.
