Any change in mother's residence or living arrangement, finances, relationship with the new baby's father, or employment status since her last study interview, her scores on the Positive and Negative Affect Schedule (PANAS) regarding her feelings and emotions during the past week, and her response to stressors in the past month on the Perceived Stress Scale (PSS)
Study Description
A five-year, multi-site, prospective cohort study about stress and resilience and their influence on maternal allostatic load as a mediator of birth outcomes and child health and development. A limited number/types of biospecimens have been collected by the study investigators. For biospecimen availability, please contact the following investigators: Chris Dunkel Schetter ([e-mail]); Madeleine Shalowitz ([e-mail]); Calvin J. Hobel ([e-mail]); Vernon M. Chinchilli ([e-mail]). Mothers who delivered a livebirth at 20 weeks gestation or more and their partners; 4836 total enrolled, 3946 of whom were eligible for mother and partner cohorts (enrollment does not include 2782 infants with data)

本研究采集的变量包括：母亲自上次研究访谈以来，在居住地址、生活安排、经济状况、与新生儿父亲的关系及就业状态方面的任何变动；其过去一周内感受与情绪对应的正负性情感量表（Positive and Negative Affect Schedule, PANAS）得分；以及过去一月内针对压力源的知觉压力量表（Perceived Stress Scale, PSS）作答情况。

Hobel，[e-mail]）、弗农·M·钦奇利（Vernon M. Chinchilli，[e-mail]）。本研究纳入妊娠20周及以上分娩活产儿的母亲及其配偶，总入组人数为4836人，其中3946人符合母亲与配偶队列的纳入标准（本次入组未纳入2782名有数据的婴儿）
