本研究验证了以下假设:实验室中测量的心血管反应性对日常生活中观察到的变化的概括性较差,这是由于在后一种情况下缺乏活动和姿势(坐、站)的标准化。37名受试者进行反应性测试,然后在实验室外进行4小时的标准化活动(受控非卧床阶段),由实验者陪同,每2天进行一次。受控的走动活动包括练习、编辑任务、快步走、解字谜和吃午餐。两个措施的现场变异性进行了检查:标准偏差和均方根的连续差异,所有的动态测量。实验室变化评分与田间变异性测量之间的相关性较差(最高r= 0.001)。23)。我们的结论是,反应性变化评分的普遍性的证据仍然很差,不能完全归因于在外地的活动的不受控制的性质。
This study tested the hypothesis that reports of poor generalizability of cardiovascular reactivity measured in the laboratory to changes observed during everyday life are due to a lack of standardization of activities and position (sitting, standing) in the latter situation. Thirty-seven subjects engaged in reactivity testing, and then in a 4-hour series of standardized activities outside the laboratory (controlled ambulatory phase), accompanied by the experimenter, on each of 2 days. The controlled ambulatory activities included alphabetizing, an editing task, a brisk walk, solving word puzzles, and eating lunch. Two measures of field variability were examined: the standard deviation and the root mean square of successive differences, of all ambulatory measurements. Associations between laboratory changes scores and measures of field variability were poor (highest r=. 23). We conclude that evidence for generalizability of reactivity change scores remains poor, and cannot be solely attributed to the uncontrolled nature of activities in the field.
