Outcome Measures

Primary Outcomes (1)

  • Change in CDRS-R (Children's Depression Rating Scale) scores from baseline

    The Children's Depression Rating Scale-Revised (CDRS-R) has a minimum score of 17 and a maximum score of 113. Higher scores indicate greater severity of depression. Primary Outcome Measure is clinical response (≥ 50% reduction in CDRS-R scores from baseline);

    Week 4 and Week 8 of treatment

Secondary Outcomes (8)

  • Change in BDI-II (Baker Depression Scale) scores from baseline

    Week 4 and Week 8 of treatment

  • Change in SCARED (The Screen for Child Anxiety-Related Emotional Disorders) scores from baseline

    Week 4 and Week 8 of treatment

  • Change in suicide risk from baseline on the C-SSRS (Columbia Suicide Severity Rating Scale)

    Week 4 and Week 8 of treatment

  • Change in PSQI (Pittsburgh Sleep Quality Index) scores from baseline

    Week 4 and Week 8 of treatment

  • Change in PedsQL4.0 (The Pediatric Quality of Life Inventory) scores from baseline

    Week 4 and Week 8 of treatment

  • +3 more secondary outcomes

Study Arms (2)

Fluoxetine combined with selenium yeast therapy

EXPERIMENTAL

In this group, participants will receive standard fluoxetine treatment along with adjunctive selenium yeast supplementation at a daily dose of 60-200 μg, aiming to investigate the role and mechanisms of selenium yeast in fluoxetine therapy.

Drug: selenium yeast supplementation

Fluoxetine combined with placebo therapy

PLACEBO COMPARATOR

Participants in this group, in addition to receiving conventional fluoxetine treatment, were administered 60-200 µg per day of a placebo identical in appearance and odor to selenium yeast as adjunctive therapy. The aim was to investigate the role of selenium yeast in fluoxetine treatment and to clarify whether it enhances the therapeutic effect.

Drug: Placebo yeast supplementation

Interventions

In this intervention, patients will receive standard fluoxetine treatment combined with placebo yeast supplementation (60-200 μg/day), which is identical in appearance and odor to selenium yeast. The aim is to clarify the specific role of selenium in the treatment of depression.

Fluoxetine combined with placebo therapy

In this intervention, patients will receive adjunctive selenium yeast supplementation at a daily dose of 60-200 μg in addition to fluoxetine. Symptom rating scales, biospecimen collection, and brain MRI will be conducted at baseline, week 4, and week 8 to investigate the adjunctive role of selenium in fluoxetine treatment for depression.
