This paper examines factors associated with the development of PTSD PTSD; military; veteran; in this population, considers issues relating to engagement in treatment, and discusses the treatment; trauma empirical support for best practice evidence-based treatment. The paper goes on to explore the challenges in those areas, with particular reference to treatment engagement and barriers to care, as well as treatment non-response. The final section addresses innovative solutions to these challenges through improvements in agreed terminology and definitions, strategies to increase engagement, early identification approaches, understanding predictors of treatment outcome, and innovations in treatment. Treatment innovations include enhancing existing treat- ments, emerging non-trauma-focused interventions, novel pharmacotherapy, personalized medi- cine approaches, advancing functional outcomes, family intervention and support, and attention to physical health.
