背景与目的：根据力量与脆弱性整合（SAVI）模型，老年人比年轻人更能避免消极的社会互动，但当他们经历消极的社会互动时，他们在情感和生理上的反应性与年轻人相同或更强。关于日常消极和积极的社会接触与交感肾上腺髓质系统（一个关键的应激途径）之间的联系以及这些联系是否存在年龄差异，人们知之甚少。这项研究考虑了消极和积极的社会互动是否与昼夜α -淀粉酶（一种测量交感肾上腺髓质系统的方法）有关，以及这些联系是否存在年龄差异。研究设计和方法：参与者来自每日健康、压力和关系研究，其中包括89个随机样本（40-95岁），他们完成了14天的每日日记访谈，每天提供四次唾液样本（醒来、醒来后30分钟、午餐和就寝时间），其中四天用于检测α -淀粉酶。结果：人们报告的负面互动较多的日子里，早晨α -淀粉酶的下降幅度更大，表明压力更大。积极互动与每日α -淀粉酶之间的联系因年龄组而异。讨论和启示：研究结果与SAVI模型一致，表明老年人对社会刺激的反应不同于年轻人。
Background and Objectives: According to the strength and vulnerability integration (SAVI) model, older people are better able to avoid negative social interactions than younger people, but when they do experience negative interactions, they are equally or more emotionally and physiologically reactive than younger people. Less is known about the links between daily negative and positive social encounters and the sympathetic adrenal medullary system (a key stress pathway) and whether there are age differences in these links. This study considers whether negative and positive social interactions are associated with diurnal alpha-amylase (a measure of the sympathetic adrenal medullary system) and whether there are differences in these links by age.Research Design and Methods: Participants were from the Daily Health, Stress, and Relationship Study, which includes a random sample of 89 individuals (aged 40-95) who completed 14 days of daily diary interviews and provided saliva samples four times a day (wake, 30 min after wake, lunch, and bedtime) for four of those days that were assayed for alpha-amylase.Results: Days in which people reported more negative interactions were associated with flatter morning declines in alpha-amylase, indicating greater stress. Links between positive interactions and diurnal alpha-amylase varied by age group.Discussion and Implications: Findings are consistent with the SAVI model indicating that older adults respond differently to social stimuli than younger people.
