Because a bit of research has indicated that this new relationship anywhere between nursing and you may stress is limited so you can women girls and boys (Wire ainsi que al., 2012), we test if or not you’ll find sex variations in the newest organization anywhere between medical and you will feature and you can condition psychological performing. We have fun with a massive national take to who’s caregiver reports regarding medical and you may care about-claimed trait and you will county emotional functioning from inside the young adulthood to evaluate these types of hypotheses.
