Overview
Brief Summary
New treatments to help to reduce the emotional dysregulation of mood disorders are critically needed. This is a study of an emotional dysregulation psychotherapy treatment in which participants will learn skills to help to down-regulate maladaptive emotional responses and learn beneficial, healthy habits. Investigators will perform symptom and behavioral assessments and scanning prior to the treatment and will then repeat scanning, symptom and behavioral assessments at the midpoint, and after the psychotherapy is completed. This collected information will assess whether the treatment can improve functioning of emotion regulation brain circuitry.
Detailed Description
Aim: To use functional magnetic resonance imaging (fMRI), before, at mid point, and after an emotional regulation intervention, to assess intervention-associated changes in brain circuitry responses to emotional stimuli. Hypothesis : The emotional regulation psychotherapy treatment will be associated with changes in emotional regulation circuitry. At the time of registration, the primary outcome "Changes in Functioning of Emotional Brain Circuitry" was the only outcome registered. This outcome is comprised of multiple measurements and was split up individually at the time of results entry and the original primary outcome measure was deleted.

Eligibility Criteria
Inclusion Criteria

Outcomes
Primary Outcomes
fMRI Functional Connectivity Changes in VPFC From an Amygdala Seed Region at Baseline and Endpoint
Time Frame: Baseline and 12 weeks
Pearson's correlations between the mean timecourse of the seed and the timecourse of each voxel between baseline and endpoint were compared at a voxel-level threshold of p\<0.001 uncorrected using statistical parametric mapping (SPM) software. If there were voxels above this threshold in the hypothesized region of interest (ventral prefrontal cortex), then the correlation values from those voxels in that region were extracted and Fisher transformed and averaged, where higher scores indicted greater connectivity. Functional connectivity differences between baseline and endpoint in regions of interest that survived the voxel-based threshold in participants who received either BE-SMART variation and had fMRI data of sufficient quality for fMRI functional connectivity analyses. The results of the mixed model analysis of those values are below.
Functional Magnetic Resonance Imaging (fMRI) Blood Oxygen-level Dependent (BOLD) Signal Changes in Left Amygdala at Baseline and at the End of the Intervention
Time Frame: baseline and 12 weeks
FMRI was performed during an emotional face processing task. Signal differences (BOLD changes) were compared between baseline and endpoint, separately for BE-SMART-DR or BE-SMART-ER, at a voxel-level threshold of p\<0.001 uncorrected using statistical parametric mapping (SPM) software. If voxels above this threshold survived in a hypothesized region of interest (amygdala and ventral prefrontal cortex, VPFC) then the signal differences in those voxels were extracted and mean values within the region for each subject were used in the analyses below. The only voxel-based finding meeting criteria was left amygdala activation decreases to fearful faces in participants receiving BE-SMART-DR. The results of the mixed model analysis of those values are below.
FMRI BOLD Signal Changes in Left Amygdala at Baseline and Midpoint
Time Frame: Baseline and 6 weeks
Signal differences (BOLD changes) between baseline and midpoint in regions of interest that survived the voxel-based threshold in participants who received either BE-SMART variation and had fMRI data of sufficient quality for fMRI activation analyses. The results of the mixed model analyses of those values are below.
