Brief Summary

Many patients with Major Depressive Disorder (MDD) and generalized Social Anxiety Disorder (gSAD) are treated with cognitive behavioral therapy (CBT) but few have meaningful improvement. MDD and gSAD are diseases of brain dysfunction that manifest as impaired emotion regulation; CBT teaches emotion regulation strategies but how it works in the brain remains largely unknown. Individual differences in brain function related to emotion regulation may make some patients better suited for CBT and CBT may remedy the brain dysfunction that underlies these disorders. This project will compare CBT with a placebo psychotherapy (i.e., supportive therapy) in MDD and gSAD to test, validate, and refine brain-based markers and examine mechanisms of change to examine how CBT works and for whom.

Detailed Description

Major Depressive Disorder (MDD) and generalized Social Anxiety Disorder (gSAD) are pervasive major public health problems. These disorders are characterized by emotion dysregulation, an inability or inefficiency to regulate negative and positive affect as reflected in common and disorder-specific symptoms (e.g., attentional bias to negative stimuli, excessive/inappropriate negative thoughts, hyperarousal, anhedonia, emotional blunting). Such dysregulation is believed to result from an imbalance between top-down 'emotion regulating' (ER) frontal nodes central in inhibitory control of bottom-up subcortical 'emotion-generating' (EG) nodes in a Fronto-Limbic Affect Regulation and Emotional Salience (FLARES) network. Therefore, successful treatment would be expected to 'normalize' neurofunctional disturbances in the FLARES network, which can be measured with fMRI and more distal units of brain function -- event-related potentials (ERPs) from electroencephalography, startle potentiation from electromyography (EMG), neurocognitive performance, and use of regulation strategies in daily life via self-report. The overarching objective of the proposed study is to understand how, when, and where CBT works and for whom to tailor treatment to improve clinical outcome.

Without precisely identified "targets" and "predictors" of change, CBT response will continue to be unpredictably varied with few achieving meaningful clinical improvement placing them at risk for relapse and recurrence. Our proposal builds on published data from our lab and others and Preliminary Data which shows FLARES function, as assayed with fMRI, ERPs, EMG, and behaviors, is sensitive to change following CBT.

Importantly, both baseline fMRI and non-fMRI units of brain-behavioral measures predict CBT response better than baseline clinical measures. Such knowledge can lead to more precise interventions aimed at capitalizing on 'strengths' or improving 'deficits' that may each exist before CBT and/or explain why CBT does not work for some patients. The dual development of fMRI ('mechanistic') and non-fMRI ('pragmatic') predictors and indices of therapeutic change is aimed at advancing precision medicine while increasing the clinical utility of 'biomarkers' in the outpatient setting. With this objective, we propose to employ well-validated paradigms to test ER and EG in the context of negative stimuli, reward processes, and fear systems in MDD and gSAD to delineate common and disorder-specific mechanisms of change and predictors of CBT outcome. We will enroll 200 patients: 100 MDD (without comorbid gSAD), 100 gSAD (without comorbid MDD) and randomize them to 12 weeks of manualized CBT or 12 weeks of 'placebo' psychotherapy (supportive therapy) (1:1 ratio). Multiple units of FLARES function will be collected in all patients before (Week 0), during (midway/Week 6) and after treatment (Week 12) to ascertain CBT 'dose' effects, and in 40 healthy controls for comparison. Pre-CBT predictors based on binary (responder/non-responder status) and continuous (extent of change) outcomes will be examined midway (Week 6), immediately after treatment (Week 12), and at 6-month follow-up.

Study Design

• Intervention Model: PARALLEL
• Primary Study Purpose: BASIC_SCIENCE
• Blinding Strategy: SINGLE

Study Groups

CBT

The clinical psychologist will use a manualized CBT approach tailored to MDD or gSAD. Over a 12-week period sessions will include core CBT strategies -- psychoeducation, cognitive intervention (e.g., cognitive restructuring), behavioral changes (i.e., fear exposure, behavioral activation strategies) and relapse prevention.

Group Type: ACTIVE_COMPARATOR

CBT

Intervention Type: BEHAVIORAL

CBT works by changing people's attitudes and their behavior by focusing on the thoughts, images, beliefs and attitudes that are held (a person's cognitive processes) and how these processes relate to the way a person behaves, as a way of dealing with emotional problems.

ST

The clinical psychologist will use an ST approach that resembles client-centered therapy of Carl Rogers (1951) which has been used as a control psychotherapy. The manual is based on supportive psychotherapy principles. Over a 12-week period sessions will emphasize reflective listening and elicitation of affect. In contrast to CBT, therapists allow patients to determine the focus of each session, pulling for emotion, validating emotions when possible, and offering empathetic comments. Therapists will refrain from delineating any CBT theoretical framework and avoided cognitive and behavioral techniques that might overlap with CBT.

Group Type: PLACEBO_COMPARATOR

ST

Intervention Type: BEHAVIORAL

Treatment designed to improve, reinforce, or sustain a patient's physiological well-being or psychological self-esteem and self-reliance
