Quantitative Impacts

RESULTS: The charts below represent the positive mental health changes reported by Warrior Expeditions veterans at the completion of their journeys.

MEASURES: Warrior Expeditions uses two standardized measures of psychopathy.

  • PCL-5: A 20-item self-report measure that assesses Post Traumatic Stress according to the DSM-5 with clinical relevance scores recommended by the Department of Veterans Affairs.
  • SA-45: A 45-item self-report measure that assesses the 9 Symptom Domain Scales of General Psychiatric Symptomology and scores are compared to norms of an outpatient clinical population.

SCORING: The scores below reflect pre and post data collected from 55 Warrior Expeditions veterans since 2013.

BACKGROUND: Since 2013, Warrior Expeditions has partnered with psychologists Dr. Shauna Joye (Air Force veteran) and Dr. Zachary Dietrich (Marine Corps veteran) to research the effects of long-term wilderness experiences on combat veterans. Each year Warrior Expeditions veterans volunteer to complete mental health surveys that assess the presence and severity of ten symptoms such as post traumatic stress, anxiety, and depression. Surveys are completed before and after their three to six-month expeditions in order to measure program impact on mental health.
