Examining early-phase symptom trajectories in interpersonal psychotherapy versus antidepressant medication for adults with depression: A dynamic time warp network analysis.

In 30 seconds

This randomized controlled trial examined symptom trajectories in adults with depression undergoing either interpersonal psychotherapy (IPT) or selective serotonin reuptake inhibitors (SSRIs) over six weeks. The study found that symptom changes were largely similar between the two treatments, with improvements in somatic symptoms of anxiety and middle insomnia preceding changes in depressed mood.

Key findings

• Symptom trajectories were largely similar for IPT and SSRIs during the first six weeks.
• Improvements in somatic symptoms of anxiety and middle insomnia preceded changes in depressed mood.
• Monitoring a broad range of symptoms may provide clinically relevant insights beyond total severity scores.
• Few indications for treatment selection based on baseline symptom profiles were identified.

Why it matters

Understanding early-phase symptom trajectories can enhance treatment monitoring and inform clinical decisions. Recognizing that symptom improvements may occur outside the core affective domain is crucial for effective patient management.
