Brief summary
The proposed investigation will determine the therapeutic potential of aripiprazole augmentation to a stable antidepressant regimen for reducing posttraumatic stress disorder (PTSD) symptoms, cognitive symptoms, psychotic symptoms, and depressive symptoms in veterans with PTSD.
Interventions
Aripiprazole: 5 mg taken once a day orally for 2 weeks, then Aripiprazole: 5-10 mg taken once a day orally for 2 weeks, then Aripiprazole: 5-15 mg taken once a day orally for 2 weeks, then Aripiprazole: 5-20 mg taken once a day orally for 2 weeks
Same as active drug.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinician Administered PTSD Scale (CAPS) | Week 2 and Week 6 | Mean change scores (Week 2 minus Week 6) in posttraumatic stress disorder symptoms. 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. |
| Brief Assessment of Cognition in Affective Disorders (BAC-A) | Week 2 and Week 6 | The BACS 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 6 (Week 2 minus Week 6). |
| Positive and Negative Symptoms Scale (PANSS) | Week 2 and Week 6 | The PANSS is a widely used measure with several subdomains, including positive symptoms, negative symptoms, and general psychopathology of schizophrenia. Lower scores are indicative of fewer symptoms; higher scores are indicative of more symptoms. Total PANSS scores range from 0-20.Mean change scores from Week 2 and Week 6 (Week 2 minus Week 6) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Connor-Davidson Resilience Scale (CD-RISC) | Week 2 and Week 6 | This scale measures resilience. Range of scores (0-100). A score of 0 is suggestive of no resilience, a score of 100 is suggestive of high level of resilience. Change scores calculated at Week 2 and Week 6 (Week 2 minus Week 6). |
| Beck Depression Inventory, Second Edition (BDI-II) | Week 2 and Week 6 | The Beck Depression Inventory-II (BDI) is a very sensitive and widely used instrument used to detect depressive symptoms. It consists of 21 items that assess the intensity of depression in both clinical and non-clinical subjects. Each item is a list of four statements arranged in increasing severity regarding a particular symptom of depression. Scores range from 0 to 63 (higher scores suggest higher levels of depression). Change scores were calculated from Week 2 and Week 6 scores (Week 2 minus Week 6). |
