Randomized controlled trial of stress management and resiliency training for depression (SMART-D)-pilot study

Area of Science:

• Psychiatry
• Clinical Psychology
• Behavioral Medicine

Background:

• Major Depressive Disorder (MDD) is linked to heightened stress sensitivity and suboptimal treatment responses.
• The relationship between stress and depression is bidirectional, suggesting interventions targeting stress may benefit MDD patients.

Purpose of the Study:

• To evaluate the efficacy of adjunctive Stress Management and Resiliency Training tailored for Depression (SMART-D) in patients with MDD receiving standard treatment.
• To compare treatment outcomes in MDD patients receiving SMART-D plus Treatment As Usual (TAU) versus TAU alone in real-world clinical settings.

Main Methods:

• A pilot randomized controlled trial (RCT) involving 27 adult participants with MDD.
• Participants were randomized to receive either adjunctive SMART-D via telehealth for 8 weeks or TAU alone.
• The primary outcome measure was the change in depression scores (Hamilton Rating Scale for Depression - HAM-D) over a 6-month follow-up, analyzed using mixed-effects models.

Main Results:

• At 3 months post-intervention, the SMART-D group showed significant reductions in depression (HAM-D) and perceived stress (PSS) compared to the TAU group.
• These significant differences were not sustained at the 6-month follow-up.
• Baseline HAM-D scores indicated mild-to-moderate symptom severity in both groups.

Conclusions:

• Adjunctive SMART-D intervention shows initial potential for improving depression and perceived stress symptoms in MDD patients earlier than standard care.
• The small sample size necessitates caution in interpreting results and highlights the need for further investigation.
• Larger-scale studies are warranted to confirm the efficacy and durability of SMART-D for Major Depressive Disorder.
