Election Study 2024This study aims to examine how the 2024 U.S. presidential election impacts individuals’ stress during election week via nightly surveys and physiological measures of cortisol, a stress hormone. Theory and limited empirical work suggest that sociopolitical contexts can influence individuals’ daily lives. For instance, in a study looking at the 2008 election, Republicans and Democrats exhibited different levels of stress hormones before the election and on election day (Trawalter et al., 2011). Although we may understand that political choices and beliefs may impact individuals’ stress response, we know little about how particular issues salient to elections (e.g., immigration, freedom, etc.) may be experienced physiologically. Election-related stress among emerging adults (18-25) remains under-explored despite growing evidence linking stress from political events to adverse health outcomes. Additionally, research shows that emerging adults who experience significant stress during high-stakes political events, such as elections, may exhibit heightened levels of cortisol, a biological marker of stress. Political issues may disproportionality affect certain populations, such as immigration, marriage, and abortion rights among refugees, sexual and gender minority individuals, ethnic and racial diverse groups, and women. As such, this study aims to examine how the U.S. presidential election and the events and topics relevant to the election impact individuals’ cortisol, the principal stress hormones of the hypothalamic-pituitary-adrenal (HPA) axis. The purpose of this study it to examine emerging adults' diurnal stress hormone profiles before, during, and after the 2024 U.S. presidential election. Using online questionnaires and salivary samples, we linked participants’ daily responses to events playing out in the U.S. elections. This study allows for a better understanding of the ways in which individuals’ political knowledge, beliefs, and attitudes related to the political scenario may be associated with physiological responses.
