Effects of Concurrent and Consecutive Repetitive Transcranial Magnetic Stimulation (rTMS) and Cognitive Bias Modification (CBM) (TMS CBM)
The goal of this study is to learn whether combining repetitive transcranial magnetic stimulation (rTMS) with a computerized behavioral intervention (imagery cognitive bias modification, CBM-I) reduces negative interpretation bias and mild-to-moderate depressive symptoms. The study will also examine neural changes in the dorsolateral prefrontal cortex (DLPFC) and whether timing of interventions affects outcomes.
The main questions it aims to answer are:
Does active TMS reduce negative interpretation bias and depressive symptoms more than sham TMS? Is delivering CBM-I concurrently with TMS more effective than delivering it consecutively (separate sessions) at reducing negative bias and depressive symptoms? Do combined rTMS + CBM-I approaches produce greater neural changes and improved cognitive control over self-referential interpretation than controls? Researchers will compare active TMS versus sham TMS, and concurrent versus consecutive delivery of CBM-I, to test effects on negative bias and depressive symptoms.
Participants will:
Receive either active rTMS or sham TMS targeting the DLPFC Complete imagery CBM-I sessions either concurrently with TMS or in separate (consecutive) sessions Undergo assessments of negative interpretation bias, depressive symptoms, and neural measures before and after the intervention

활성 비교기: CC-R-CBM
Concurrent, Real TMS, CBM
|
The rTMS group will receive 10 Hz stimulation to the left DLPFC at an intensity of 120% of the resting motor threshold of the right abductor pollicis brevis (APB) muscle with 4 sec trains and 11 sec intertrain intervals for 3000 pulses.Specifically in our study, we combine both intervention, but applying them concurrently and consecutively between groups.
Imagery CBM-I focuses on 2 cognitive aspects, mental imagery and interpretation.
Participants will be presented with scenarios in which they have to imagine themselves to be in and practice constructing positive endings or interpretations for them.

가짜 비교기: CC-S-CBM
Concurrent, Sham TMS, CBM
|
Imagery CBM-I focuses on 2 cognitive aspects, mental imagery and interpretation.
Participants will be presented with scenarios in which they have to imagine themselves to be in and practice constructing positive endings or interpretations for them.
The TMS coil will be rotated 90 degrees, and will not be delivering active stimulation to the participant.
The intensity will be set to 30 and the TMS device will be active, generating enough sound effect but no real stimulation for sham control.
