Primary outcomes

  1. Change From Baseline in Hamilton Depression Scale (HAM-D) at Week 12

    Time frame: At Baseline and Week 12.

    HAM-D, clinician-rated interview, measures presence of depressive symptoms in 17 areas (symptoms such as depressed mood, guilt feelings, suicide, sleep disturbances, anxiety levels and weight loss). Total score ranges from 0 to 52; higher scores indicate more depression. Change from baseline: mean at observation minus mean at baseline.

Secondary outcomes

  1. Change From Baseline in Sheehan Disability Scale (SDS) Total Score at Week 12

    Time frame: At Baseline and Week 12.

    Participant rated scale was used to assess the effect of the participant's symptoms on their work/social/family life. Total scores range from 0 to 30 with higher values indicating greater disruption in the participant's work/social/family life. Individual item scores range from 0 to 10.

  2. Clinical Global Impression Scale - Improvement (CGI- I) Score at Week 12

    Time frame: At Baseline and Week 12.

    CGI-I: 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved) on the scale. Higher score = more affected. Change = score at observation minus score at baseline.

  3. Clinical Global Impressions Scale - Severity of Illness (CGI-S) at Week 12

    Time frame: At Baseline and Week 12.

    CGI-S: 7-point clinician rated scale to assess severity of participant's current illness state; range: 1 (normal - not ill at all) to 7 (among the most extremely ill patients). Higher score = more affected. Change: score at observation minus score at baseline.

  4. Change From Baseline on Work and Activities Item of HAM-D17 at Week 12

    Time frame: At Baseline and Week 12.

    The Work and Activities Item of the HAM-D17 is item 7 of HAM-D17. Scoring range from 0 to 4.

  5. Change From Baseline in Adjusted Mean on Montgomery-Asberg Depression Rating Scale (MADRS) at Week 12

    Time frame: At Baseline and Week 12.

    Measures the overall severity of depressive symptoms. The MADRS has a 10-item checklist. Items are rated on a scale of 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms).

  6. Change From Baseline on Worry Anxiety Tension Scale (WATS) at Week 12

    Time frame: At Baseline and Week 12.

    WATS: a self-administered, 3-question rating scale assesses worry, anxiety, and tension. Each item was a visual analog scale on which the participant circles a number from 0 to 10. Higher scores indicated worse function. WATS total score was the sum of the 3 items. If 1 item was missing, the total score would be missing.

  7. Change From Baseline on Stress and Social Support Scales at Week 12

    Time frame: At Baseline and Week 12.

    Stress and Social Support Scales: self-administered rating scale where item 1 is the stress vulnerability scale measuring how much the subject was set back by stressful events on an 11-point scale ranging from 0 (not at all) to 10 (extremely) and item 2 is an 11-point scale ranging from 0 to 100 percent of the amount of support the subject received from relatives and friends.
