这项重复性研究旨在检验女性社区样本中心血管反应性个体差异对基于标准化PC的认知任务协议（Kamarck et al., 1992）的可靠性。30名女性，包括黑人和白人（25-44岁），在社区为基础的检测点的移动实验室进行两次重新检测，间隔1个月。心率和血压反应性测量是通过比较休息和三个方案任务期间的评估来获得的。使用阻抗心动图评估预射期、卒中容量和总外周阻力变化。与先前对男性的研究一样，心率、收缩压和舒张压对该方案的反应的个体差异是高度可靠的。80或更高)，当数据跨三个任务和两个测试会话聚合时。心脏收缩力（射血前期）和每搏容量变化对这些任务的可靠性超过0.70。这种反应性评估程序现已在三项研究中产生了可靠的结果，并且似乎可以在不同的样品和环境中导出。
This replication study was designed to examine the reliability of individual differences in cardiovascular responsivity to a standardized PC‐based cognitive task protocol (Kamarck et al., 1992) in a female community sample. Thirty women, both black and white (ages 25–44 years), were administered the protocol twice with a 1‐month retest interval using a mobile laboratory at a community‐based testing site. Measures of heart rate and blood pressure reactivity were obtained comparing assessments taken at rest and during three protocol tasks. Preejection period, stroke volume, and total peripheral resistance changes were estimated using impedance cardiography assessments. As in previous studies with males, individual differences in heart rate and systolic and diastolic blood pressure responses to the protocol were highly reliable (.80 or greater) when data were aggregated across three tasks and two testing sessions. Reliability of cardiac contractility (preejection period) and stroke volume changes to these tasks exceeded .70. This reactivity assessment procedure has now produced reliable results in three studies and appears to be exportable across diverse samples and settings.
