Outcome Measures
Primary Outcome Measures
- Change From Baseline to Week 8 in the Children's Depression Rating Scale, Revised (CDRS-R) Total Score (n=102, 104, 106) [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. Mean change from baseline was adjusted for the baseline total score, age group and gender.
Secondary Outcome Measures
- Change From Baseline to Week 8 in the Clinical Global Impression of Severity (CGI-S) Score (n=102, 105, 106) [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. Mean change from baseline was adjusted for the baseline total score, age group and gender.
- Percentage of Participants by Clinical Global Impression Improvement (CGI-I) Score at Weeks 1, 2, 3, 4, 6, and 8 [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 equals (=) more affected.
- Percentage of Participants With a CGI-I Response Defined as a Score of 'Very Much Improved' or 'Much Improved' [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) or 2 (much improved) on the scale. Higher score = more affected.
