- Brief Assessment of Cognition in Affective Disorders (BAC-A) [ Time Frame: Week 2, Week 10 ]Mean change scores (Week 2 minus Week 10) to assess cognitive changes. 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).
- Clinician Administered PTSD Scale (CAPS) [ Time Frame: Week 2, Week 10 ]
Mean change scores (Week 2 minus Week 10) 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.
- Quick Inventory of Depressive Symptomatology (QIDS) [ Time Frame: Week 2, Week 10 ]The QIDS total scores range from 0 to 27. Total score is obtained by adding the scores for each of the nine symptom domains of the DSM-IV Major Depressive Disorder (MDD) criteria: depressed mood,loss of interest or pleasure,concentration/decision making,self-outlook,suicidal ideation, energy/fatigability,sleep,weight/appetite change,and psychomotor changes. Each item is rated 0-3 (0=least or no severity, 3=greatest severity).
