“…From a theoretical perspective, our findings may reveal why numerous inconsistencies in SRS literature exist (Altemus et al, 2001;Balodis et al, 2010;Cacioppo et al, 1998;Engert et al, 2011;Karhula et al, 2017;Khoury et al, 2020;Kudielka et al, 2004;Laurent et al, 2016;Looser et al, 2010;Maruyama et al, 2012;Myers et al, 2017;Nater et al, 2006;Quas et al, 2014;Rahal et al, 2020;Smeets, 2010;Valentin et al, 2015;Weber et al, 2010). Not only is it vital to consider the entire HPA response trajectory (to account for significant covariation in cortisol reactivity, peak, and recovery), but a multisystem approach using indices across SRS is needed as significant relationships between two systems disappear when accounting for the combined interactions across all three systems.…”
