Moral distress has been the focus of Dr. Tracy Trothen’s research since the early 1990s, when her mentor Dr. George Webster introduced her to the topic. Moral distress occurs when one’s core values are compromised and this can lead to moral residue (accumulated left-over moral distress). Dr. Trothen has recently co-authored an article on the harmful effects that moral distress can have on healthcare practitioners with conscientious objections.
