Concurrent and consecutive rTMS plus CBM for depression in adults

Official title: Effects of Concurrent and Consecutive Repetitive Transcranial Magnetic Stimulation (rTMS) and Cognitive Bias Modification (CBM)

Run by The University of Hong Kong · NCT07636694 · Data updated 2026-11-12

This study tests whether combining rTMS with a computer-based CBM-I program can reduce negative thinking and depressive symptoms in adults with major depressive disorder.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with major depressive disorder, fluent in Chinese, right-handed, with BDI-II scores 14-28, and eligible for MRI and rTMS.

Probably not a fit

Individuals with contraindications to rTMS, MRI, or with severe medical or neurological conditions may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with major depressive disorder will receive either active or sham rTMS, and CBM-I will be delivered either concurrently with rTMS or in separate sessions. The trial will measure changes in depressive symptoms and negative interpretation bias, and explore brain changes in the dorsolateral prefrontal cortex. Neural and cognitive outcomes will be compared across delivery modes and between active versus sham stimulation. MRI feasibility will be considered to assess brain activity and cognitive control related to self-referential interpretation.

Why it matters

Potential benefit: If successful, participants may experience greater reductions in depressive symptoms and negative thought patterns, with potential neural changes supporting improved cognitive control.

How similar studies have gone: Previous work suggests neuromodulation plus cognitive bias modification can influence depressive symptoms, but concurrent versus sequential delivery is less established.
