The primary objective of the study is to implement and evaluate the effectiveness of an evidence-based intervention, STAIR-NT, which will be adapted with Goal Management Training (GMT). A small-scale randomized control pilot will be conducted using the adapted intervention to examine implementation (i.e., feasibility, acceptability) and improvements in short-term PTSD, as well as secondary mental health outcomes (e.g., anxiety, and depression symptoms, substance misuse) among a first responder population with a history of TBI and PTSD.
