Outcome Measures

Primary Outcome Measures :
  1. Change From Baseline to Week 8 in the Children's Depression Rating Scale, Revised (CDRS-R) Total Score [ Time Frame: Baseline and Week 8 ]
    Clinician-rated interview-based scale (with both child and parent or guardian) to assess 17 distinct symptom areas to derive an index of depression severity. Discrepancies between informants' responses were resolved by using most impaired rating given by valid informant. Rated on a 7-point scale; range from 1 (no impairment) to 7 (indicates greater impairment). Total score calculated as sum of the 17 items (range 1 to 119); higher score indicates greater impairment. Adjusted mean presented.


Secondary Outcome Measures :
  1. Change From Baseline to Week 8 in the Clinical Global Impression of Severity (CGI-S) Score [ Time Frame: Baseline and Week 8 ]
    A 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. Adjusted mean presented.

  2. Percentage of Participants by Clinical Global Impression Improvement (CGI-I) Score at Weeks 1, 2, 3, 4, 6, and 8 [ Time Frame: Baseline and Weeks 1, 2, 3, 4, 6, and 8 ]
    A 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.

  3. Percentage of Participants With a CGI-I Response Defined as a Score of 'Very Much Improved' or 'Much Improved' [ Time Frame: Weeks 1, 2, 3, 4, 6, and 8 ]
    A 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.
