This project aims to investigate the effectiveness of existing common antidepressants in adolescents with MDD who did not respond to their first treatment. Adolescents ages 12 to 17, currently taking a prescribed selective serotonin reuptake inhibitor (SSRI) at least 8 weeks and still experiencing depression, participate in a 8-week randomized treatment study that includes one of three conditions: (1) switching to sertraline , (2) switching to duloxetine , (3) augmentation of their original SSRI with aripiprazole.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| response rate of Children's Depression Rating Scale (CDRS-R) scores | Baseline of treatment period, 4 weeks, 8 weeks | The primary outcomes are the treatment response rate (reduction rate of CDRS-R≥50%). The CDRS-R is a scale consisting of 17 items that are evaluated by clinicians to assess the intensity of depressive symptoms in adolescents, with items scored on scales of 1 to 5 or 1 to 7, resulting in a possible total score range of 17 to 113，higher scores mean a worse outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Baker Depression Scale（BDI-II) scores from baseline | Baseline of treatment period, 4 weeks, 8 weeks | Change in BDI-II scores from baseline，The BDI is a self-report rating scale containing 21 items. Based on the BDI scores, depression can be classified into six levels: normal (1-10), mild mood disorder (11-16), borderline clinical depression (17-20), moderate depression (21-30), severe depression (31-40), and extreme depression (over 40).Higher scores mean a worse outcome. |
| Change in The Screen for Child Anxiety-Related Emotional Disorders (SCARED) scores from baseline | Baseline of treatment period, 4 weeks，8 weeks | The SCARED is employed to evaluate child anxiety symptoms. Each question is rated from 0 to 2, with 0 denoting not true or hardly ever true, 1 denoting somewhat true or sometimes true, and 2 denoting extremely true or often true. The maximum total score is 63. Higher scores mean a better or worse outcome. |
| Change in CGI-S (Clinical Global Impressions-Severity Scales) scores from baseline | Baseline of treatment period, 4 weeks, 8 weeks, | Improvement in overall clinical impression severity（ 7-point scale, with 1 being normal and 7 being among the most severely damaged |
| Adverse Event (AE) or Serious Adverse Event (SAE) | Baseline of treatment period, 1 month, 2 months, | Change in suicide risk from baseline on the C-SSRS (Columbia Suicide Severity Rating Scale), Adverse Event (AE) or Serious Adverse Event (SAE) |
