Around 10% of post-active veterans experience post-traumatic stress disorder (PTSD) many years post-mission. PTSD in veterans is frequently associated with challenges in emotion regulation, aggression, suicidality, and financial and psychosocial stress. In 2018, a 12-week clinical treatment programme, the Veterans Intensive Treatment Unit (VIBU), was developed for veterans experiencing these psychiatric symptoms, for whom conventional treatments had proven ineffective. The VIBU provides patients with trauma-focused and dialectical behaviour therapy (DBT). A recent study revealed that the VIBU was effective in reducing psychiatric symptoms. However, a recurrence of symptoms was observed in patients a few months after discharge. Consequently, an aftercare programme consisting of hybrid DBT is offered to consolidate and repeat the DBT skills and apply them in daily life.
