Blame Rebalance fMRI Feedback Proof-of-concept (GUIMRINFB1)
Rebalancing Blame Using fMRI Neurofeedback: a Double-blind Controlled Clinical Proof-of-concept Trial in Remitted Major Depressive Disorder
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Specific aim 1: Demonstrate that anterior temporal lobe (ATL)-septal/subgenual cingulate (SCSR) coupling for guilt can be increased through one session of neurofeedback in the group seeing visual feedback based on increasing correlations during the guilt condition compared with the group seeing visual feedback based on keeping correlations at the same level during the guilt condition.
Specific aim 2: Demonstrate that this increase in coupling is selective for guilt relative to indignation.
Specific aim 3: Demonstrate that mood is not negatively affected by neurofeedback.
Specific aim 4: Explore whether this short intervention decreases self-hate on the Interpersonal Guilt Questionnaire (Portuguese translation) and increases self-esteem on the Rosenberg scale (both show significant correlations with SCSR-ATL coupling across major depressive disorder and control groups in our Manchester study), or if these measures are not available, decreases negative affect on the Positive and Negative Affect Scale.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: GUILT-INCREASE-CORRELATION
Patients in this group will receive visual feedback that reinforces increasing the correlation in fMRI signal between the right superior anterior temporal and septal-subgenual regions during the retrieval of predefined guilt-related autobiographical episodes.
During the indignation condition, visual feedback will reinforce stabilization of the preceding degree of correlation.
|
This uses a novel software "FRIEND" created at IDOR in Rio de Janeiro, Brazil.
The software is used on a regular clinical fMRI scanner
|
Active Comparator: GUILT-STABILIZE-CORRELATION
Patients in this group will receive visual feedback that reinforces stabilization of the preceding degree of correlation in fMRI signal between the right superior anterior temporal and septal-subgenual regions during the retrieval of predefined guilt-related autobiographical episodes.
During the indignation condition, visual feedback will also reinforce stabilization of the preceding degree of correlation.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Increase in correlation between anterior temporal and subgenual frontal fMRI signal for guilt relative to indignation
Time Frame: change from baseline after one session of fMRI neurofeedback training
|
Correlations are computed by using average signal in the most highly activated voxels within a priori regions of interest in the right superior anterior temporal and septal/subgenual cingulate region.
The same a priori regions are also used to provide neurofeedback.
|
change from baseline after one session of fMRI neurofeedback training
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Beck Depression Inventory
Time Frame: Change from baseline after one session of fMRI neurofeedback training
|
This is an outcome measure to ensure the safety of our intervention, we expect that one session of fMRI neurofeedback will not lead to a significant increase in Beck Depression Inventory scores when comparing scores after and before the training session.
|
Change from baseline after one session of fMRI neurofeedback training
|
Interpersonal Guilt Questionnaire - Self-hate subscale
Time Frame: Change from baseline after one session of fMRI neurofeedback training
|
This is an exploratory outcome measure to determine whether there is a detectable effect on self-blaming emotions after one session of fMRI neurofeedback.
This is not our primary aim in that this study is primarily designed to determine feasibility and safety rather than efficacy.
|
Change from baseline after one session of fMRI neurofeedback training
|
Rosenberg Self-Esteem Scale
Time Frame: Change from baseline after one session of fMRI neurofeedback
|
This is an exploratory outcome measure to determine whether there is a detectable effect on global self-esteem after one session of fMRI neurofeedback.
This is not our primary aim in that this study is primarily designed to determine feasibility and safety rather than efficacy.
