We have explored this question in both daily stress studies and laboratory studies. Married couples sampling cortisol over several days showed positively correlated levels of momentary cortisol and negative mood, with stronger linkages seen in more distressed couples. In parents and adolescents engaged in a laboratory-based conflict discussion, we found that momentary cortisol levels are linked across the family triad, and time-lagged analyses suggest that fathers drive changes in youths&#8217; cortisol, youths drive mothers&#8217; cortisol changes, and mothers drive fathers&#8217; cortisol changes.<\/p>\n<p>In an additional, related line of research, we have found daily patterns of cortisol to be linked with marital satisfaction, the division of household labor, and the way people describe their homes. For example, we have found that unhappily married women have flatter slopes of cortisol, considered a marker of poor adaptation to stress. We have also found that other aspects of the family environment, like the way women describe their home spaces and the division of household labor, are linked with cortisol patterns and physiological recovery at the end of the day.<\/p>\n<p><em>Collaborators: Rena Repetti, UCLA; Gayla Margolin, Brian Baucom, Lauren Shapiro, Aubrey Rodriguez, Esti Iturralde, USC<\/em><\/p>\n\n\n\n<\/div>\n                        \n                    <\/div>\n\n\n                    \n                        \n                            \n<div class=\"f--field f--image\">\n\n    \n    \n    \n    \n    \n    \n              \n      <img decoding=\"async\"\n                            src=\"https:\/\/dornsife.usc.edu\/nestlab\/wp-content\/uploads\/sites\/296\/2023\/09\/Screenshot-2023-09-22-at-2.42.17-PM-768x432.png\"\n          srcset=\"https:\/\/dornsife.usc.edu\/nestlab\/wp-content\/uploads\/sites\/296\/2023\/09\/Screenshot-2023-09-22-at-2.42.17-PM-1280x720.png 1280w,https:\/\/dornsife.usc.edu\/nestlab\/wp-content\/uploads\/sites\/296\/2023\/09\/Screenshot-2023-09-22-at-2.42.17-PM-768x432.png 768w\"          sizes=\"(min-width:1024px) 23vw, (min-width:768px) 39vw, 83vw\"\n        \n                  role=\"none\"\n        \n        \n                                      \/>\n\n    \n    \n  \n  \n\n<\/div>\n\n                    \n                <\/div>\n\n            \n        <\/div>\n    \n\n  <\/div><\/div>\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--spacer \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--spacer\"\n    \n      >\n\n    \n\n  <\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":180,"featured_media":172,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-152","page","type-page","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
