Brief Summary

An increasing literature shows that omega-3 fatty acids provide numerous health benefits, including a variety of psychiatric symptoms and disorders including stress, anxiety, cognitive impairment, mood disorders (major depression and bipolar disorder) and schizophrenia. Omega-3 fatty acids may additionally represent a promising treatment strategy in patients with PTSD. Moreover, given its beneficial cardiovascular effects, adjunctive omega-3 fatty acids may also benefit the general health status of these veterans, who frequently present with a variety of comorbid medical disorders.

Outcome Measures

Primary Outcomes (2)

  • Clinician-Administered PTSD Scale (CAPS)

    Mean change scores in posttraumatic stress disorder symptoms (Week 10 (Week 8 Post-Randomization) minus Week 2 (Baseline)). Scores may range from 0 (no symptoms) to 136 (severe symptoms; score of 136 is based on the first 17 CAPS items administered). A reduced CAPS score indicates a reduction in (improvement) PTSD symptoms, while an increase in CAPS score indicates an increase (worsening) in PTSD symptoms.

    Week 2 (Baseline) and Week 10 (Week 8 Post-Randomization)

  • Brief Assessment of Cognition in Affective Disorders (BAC-A)

    Mean change scores to assess cognitive changes (Week 10 (Week 8 Post-Randomization) minus Week 2 (Baseline)). The BAC-A includes brief assessments of executive functions, verbal fluency, attention, verbal memory, working memory and motor speed. Z-scores are calculated from composite scores. Higher z-scores are indicative of better cognitive performance, lower z-scores are indicative of lower cognitive performance. Range of z-scores anticipated to be between -3 and 3. Mean change scores from week 2 and week 10 (Week 2 minus Week 10).

    Week 2 (Baseline) and Week 10 (Week 8 Post-Randomization)

Secondary Outcomes (5)

  • Quick Inventory of Depressive Symptomatology (QIDS)

    Week 2 (Baseline) and Week 10 (Week 8 Post-Randomization)

  • Connor Davidson Resilience Scale (CD-RISC)

    Week 2 (Baseline) and Week 10 (Week 8 Post-Randomization)

  • Continuous Performance Test (CPT)

    Week 2 (Baseline) and Week 10 (Week 8 Post-Randomization)

  • Trail Making A
