Background: Veterans with post-traumatic stress disorder (PTSD) often experience complex and persistent symptoms that extend beyond the scope of trauma-focused treatments. The Positive Health framework offers an integrative approach to health and well-being, yet its application in veteran populations remains unexplored. This randomized controlled trial investigated the effects of integrating the Positive Health dialogue tool into trauma-focused treatment for veterans with PTSD. The study aimed to evaluate its impact on recovery indicators, including quality of life, PTSD symptoms, and psychosocial functioning. Methods: Forty-four veterans diagnosed with PTSD were randomly assigned to either a treatment group, which received two additional sessions using the dialogue tool alongside standard trauma-focused therapy, or a control group receiving treatment as usual. Outcomes were measured at baseline, 6 months, and 12 months using validated instruments, including the MANSA, PCL-5, and TRACK 2.0. Results: Although both groups showed improvements over time in PTSD symptoms and psychosocial functioning, there were no statistically significant differences found between the treatment and control groups across various recovery indicators. Conclusions: The limited scope, lack of iintegration, and timing of the intervention may have contributed to the absence of measurable effects. While the dialogue tool did not yield additional benefits beyond standard treatment, the findings underscore the need for more structured, integrated, and timely recovery-oriented interventions. Trial registration: The study was approved by the Medical Ethics Committee of Maastricht University (METc azM/UM) and registered under number NL72664.068.20 on July 7, 2020. This study was funded by the Dutch National Care System for Veterans (Landelijk Zorgsysteem voor Veteranen, LZV), which supports research aimed at improving mental health care for military veterans in the Netherlands.
