Primary

MeasureTime frameDescription
Change in depression as assessed by the Hamilton Depression rating Scale (HAM-D)Baseline, 6 weeks follow upThis is a 13 item questionnaire and each is scored from 0-2 for a maximum score of 26 , a higher score indicating worse outcome

Secondary

MeasureTime frameDescription
Percentage of participants that show a remission of depressive symptoms as assessed by the HAM-D scale.from baseline to end of study (6 week follow up)Remission of depressive symptoms are defined by a score of ≤7 on the HAM-D. This is a 13 item questionnaire and each is scored from 0-2 for a maximum score of 26 , a higher score indicating worse outcome
Percentage of participants that show a response as assessed by the HAM-D scalefrom baseline to end of study (6 week follow up)Response rate is defined by ≥ 50 % reduction in depression score(HAM-D). This is a 13 item questionnaire and each is scored from 0-2 for a maximum score of 26 , a higher score indicating worse outcome
Number of participants that show early improvement as defined by >20% improvement in HAM-D depression scoreFrom baseline to week 2 visitThis is a 13 item questionnaire and each is scored from 0-2 for a maximum score of 26 , a higher score indicating worse outcome
