CHANGES IN DAILY STRESS AND WELL-BEING

本应用程序寻求支持，以扩大对日常压力源和福祉的全国调查（项目2），从新的受访者样本（25-54岁）收集数据。这些额外的参与者（n = 800）将从MIDUS项目1调查提出的新队列中随机选择。子样本将由来自密尔沃基样本的600名随机数字拨号（RDD）参与者和200名非裔美国人参与者组成。项目2的参与者将与大约15年前进行的第一波数据收集的相同年龄的受访者进行比较。一个成年人的样本

This application seeks support to extend a national investigation of daily stressors and well-being (Project 2) by collecting data from a new sample of respondents (25-54 years of age). These additional participants (n = 800) will be randomly chosen from the new cohort proposed by the MIDUS Project 1 survey. The subsample will be comprised of 600 random digit dialed (RDD) participants and 200 African American participants from the Milwaukee sample. The Project 2 participants will be compared to respondents of the same age from the first wave of data collection conducted approximately 15 years eariier. A sample of adults spanning the same age range as the initial sampling period will allow us to assess the effects of the recent economic recession on daily well-being. Some age groups may be particularly vulnerable to an economic downturn. Younger adults who are beginning their careers may be particularly at risk for distress and economic concern. Individuals low in socioeconomic status may also lack the resources to weather an unstable economy. The specific aims are (1) To assess age differences and period effects in the links between multiple aspects of daily stressors and daily well-being among people aged 25-54 in 1995/1996 compared to people aged 25-54 in 2011/2012; (2) To examine how vulnerability and resilience factors influence exposure and reactivity to daily stressors, and how these associations may be moderated by age and period effects; (3) To investigate age and period differences in associations between self-reported daily stress processes and disruption of diurnal rhythms of salivary Cortisol and sulfated dehydroepiandrosterone (DHEA-S), hormones ofthe stressresponsive hypothalamic-pituitary-adrenal (HPA) axis, as well as salivary alpha amylase (sAA), a biological marker of the sympathetic-adrenal-medullary (SAM) axis; (4) To assess the extent to which daily stressors impact two different aspects of everyday cognition: cognitive interference (e.g., intrusive thoughts) and memory failures. These new respondents will follow the same protocol as the previous Project 2 cohort, a protocol consisting of an 8-day telephone diary study of self-reported daily stress and well-being combined with multiple daily assessments of saliva (4 occasions x 4 days). The new Project 2 respondents will also participate in the other MIDUS Projects. A rich set of sociodemographic, physical health, personality, and cognitive measures assessed by Projects 1 and 3 will be used to predict exposure, as well as physical and emotional reactivity to daily stressors. In addition, data from Projects 4 and 5 will allow us to examine how daily stress processes measured in Project 2 are related to neurobiological indicators of health.
