Latent growth curve methodology was used to model systolic blood pressure reactivity and recovery from the cold pressor test. A piecewise regression approach permitted the separate but simultaneous modeling of the two components (reactivity and recovery) of the stress process. Data came from a study of 99 participants classified on the basis of gender, ethnicity, and family history of hypertension. Their systolic blood pressure was assessed at rest, during the cold pressor test, and during a task recovery period. A measure of task appraisal and readings from ambulatory blood pressure monitoring during a workday were also examined. The article illustrates a step-by-step approach to modeling reactivity and recovery. Results indicated that both reactivity and recovery were associated with subsequent systolic blood pressure at work.
采用潜在生长曲线方法对收缩压反应性以及冷加压试验后的恢复情况进行建模。分段回归方法允许对压力过程的两个组成部分（反应性和恢复）进行单独但同时的建模。数据来自一项对99名参与者的研究，这些参与者根据性别、种族和高血压家族史进行分类。在静息状态、冷加压试验期间以及任务恢复期对他们的收缩压进行了评估。还检查了任务评估指标以及工作日期间动态血压监测的读数。本文阐述了一种对反应性和恢复情况进行建模的逐步方法。结果表明，反应性和恢复情况均与随后工作时的收缩压相关。
