Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Profile of Mood States (POMS)
Time Frame: End of study (Baseline - time 0 and approximately 8 weeks later)
The POMS measures individuals' mood states. This is a validated scale to measure positive and negative mood states. The POMS contains 30 items and assesses six identified mood factors: Tension-Anxiety, Depression-Ejection, Anger- Hostility, Vigor-Activity, Fatigue-Inertia, and Confusion-Bewilderment. Scoring of the instrument provides a global score of 0 to 120 or individual domain scores. Lower scores indicate better mood state. The POMS brief form is a simple self-rating instrument.
End of study (Baseline - time 0 and approximately 8 weeks later)
