Outcomes
Primary Outcomes
Change from baseline in the Hamilton Anxiety(HAMA) Rating Scale total score at endpoint
Time Frame: from baseline to week 8
The HAMA Scale consist of 14 items that include psychic, somatic, and behavioral symptoms associated with anxiety. Each items is rated on a 5-point scale of 0(not present) to 4(very severe) so that scores may range from 0 to 56, with high scores indicating greater illness severity.
