Together, the contributions provide an in-depth examination of the current understood causes, impacts, and treatments of and for posttraumatic stress, mobilizing academic, administrative, and clinical knowledge, and lived experience to inform ongoing and future work in the field. Drawing from range of different topics, fields of study, and research methods, this text will appeal to readers across medical, mental health, and academic disciplines.
