Outcome Measures

Primary Outcome Measures

  1. Change in the Hamilton Rating Scale for Anxiety (HAM-A) Total Score [Baseline to week 4]

    HAM-A total score 0-56 units, 14 questions scored on scale of 0-4 (0= Not present, 4=Very severe) . Higher HAM-A scores indicate higher levels of anxiety Change : score at week 4 minus score at randomization

Secondary Outcome Measures

  1. Change in Hospital Anxiety and Depression Scale for Anxiety (HADS-A) Total Score [Baseline to week 4]

    HADS-A total score 0-21 units, 0 is the best, Higher total scores indicate a higher severity of the mood or anxiety disorder Change : score at week 4 minus score at randomization

  2. Change in Psychic Anxiety Factor as Measured by HAM-A Psychic Cluster Score [Baseline to week 4]

    The HAM-A psychic anxiety cluster score 0-28 units consists of 7 questions scored on scale of 0-4 (0=Not present, 4=Very severe) . Higher scores indicate higher levels of psychic anxiety disorder. Change: score at week 4 minus score at randomization

  3. Change in Somatic Symptoms as Measured by HAM-A Somatic Cluster Score [Baseline to week 4]

    The HAM-A Somatic cluster score 0-28 units consists of 7 questions scored on scale of 0-4 (0=Not present, 4=Very severe ) . Higher scores indicate higher levels of psychic anxiety disorder.

  4. Change in Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) Percent Maximum Total Score [Baseline to week 4]

    Q-LES-Q total score is the sum of the first 14 times of Q-LES-Q, and this total score is converted to a % maximum total score by : Q-LES-Q total score /70 x 100%, Larger values indicate a higher perceived quality of life enjoyment and satisfaction. Change : percentage at week 4 minus percentage at randomization
