Study Details

Study Description

Brief Summary

Heart-Smile Training (HST) is a compassion and loving-kindness-based intensive introduction program consisting of a 3-day retreat, 4-weeks of weekly 2 hour meetings, and a 1-day final retreat. This study is a randomized controlled trial study to evaluate the effectiveness of Heart-Smile Training as compared to the passive control group on measures of neural, physiological, and clinically-relevant outcomes among individuals with symptoms of depression. Participants will be randomized to either the HST group or a waitlist control group. Both groups will complete assessments before and after HST including electroencephalography (EEG), electrocardiogram (EKG), electrodermal activity tests, and self-report surveys. All study activities except surveys will be conducted in person.

Detailed Description

This will be a randomized controlled trial with two arms: Heart-Smile Training Intensive Introduction Program (HST-IIP) vs. a waitlist control group. These two arms will be compared on measures of neural, physiological, and clinically-relevant outcomes.

The investigators will enroll up to 50 adult volunteers from the general population from the ages of 18 to 60 with depression, with Computerized Adaptive Test- Depression Inventory (CAT-DI) scores from 35-75. Volunteers interested in the study will be consented and screened for their eligibility. Eligible participants will be randomized to join either the HST-IIP arm or a waitlist control arm after completing all baseline assessments and the EEG session.

Both the HST-IIP and waitlist arm will complete a baseline measurement session between study weeks -3 to 0, before starting any group sessions. Prior to completing the baseline measurement section, they will be randomized to either HST-IIP or the waitlist arm. Participants enrolled in the HST-IIP arm will join the intervention group between week 1 to 4. The waitlist arm will not join any program between week 1 to 4. They will continue their treatment as usual without any change in their therapy session or medication. Both arms will complete weekly survey measures for 4 weeks. Both arms will then complete a post measurement session during study weeks 5 to 7.

At both baseline and post-intervention measurement sessions, all participants will complete in-person study tasks and remote surveys. In-person study visits will include neurophysiological measures; EEG, EKG, skin conductance, and respiration rate measures and will take place at the Spaulding Rehabilitation Hospital/Mass General Brigham in Charlestown, MA. Remote self-report surveys will be completed by participants during baseline and post-measurement either at home through a link secure to the Cambridge Health Alliance (CHA) REDCap database sent via email or using an electronic device at the CHA Center for Mindfulness and Compassion.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Heart-Smile Training Intensive Introductory Program (HST-IIP) Group

The HST-IIP group will complete the Heart-Smile Training Intensive Introductory Program during weeks 1 through 4 of the study.

Behavioral: Heart-Smile Training Intensive Introduction Program (HST-IIP)
Heart-Smile Training (HST) is an interoceptive compassion program designed to develop the qualities of compassion, empathy, and kindness for oneself and others with a focus on interoceptive awareness. It is unique from other compassion trainings in its focus on 1) embodiment of warmth and tenderness of compassionate feeling with a compassionate body scan meditation, 2) development of an "authentic presence," characterized by a warm feeling of loosened attachment to ego-based self, and 3) cultivation of joy triggered by genuine smile to oneself. HST-IIP is a 3-day/4-week/1-day interoceptive compassion program that shares the same core elements and practices as HST 3-day intensive program. Unlike HST, the format of the HST-IIP has an extended duration to develop self-regulation through the cultivation of emotional and behavioral regulation.

No Intervention: Waitlist Control Group

The waitlist arm will not complete any intervention during their time in the study. They will continue their treatment as usual without any change in their therapy session or medication. After their post study visits are complete, they will have the opportunity to participate in Mindfulness-Based Intervention courses through the Cambridge Health Alliance Center for Mindfulness and Compassion.

Outcome Measures

Primary Outcome Measures

  1. Change from Baseline heartbeat evoked potential (HEP) at 4 weeks [Up to 11 weeks]

    HEP has been used as a marker to assess interoceptive awareness between depressed individuals and normal control (MacKinnon et al., 2013). The second primary outcome is to evaluate the effects of HST-IIP on EEG heartbeat evoked potentials (HEP) and the correlation between the pre- versus post-intervention changes in HEP amplitude and changes in depression severity.

Secondary Outcome Measures

  1. Change from Baseline Gamma Band Frequency at 4 weeks [Up to 11 weeks]

    Gamma band frequency (>35 Hz) has been demonstrated as an objective measure of meditation experience across techniques (Braboszcz et al., 2017) and is associated with positive emotionality and enhanced affective regulation. Therefore, the primary outcome measure is an EEG measure of amplitude (power) in the gamma frequency band (>35 Hz), during both resting and compassionate state induction, from baseline to post-intervention.

  2. Change from Baseline Depression (CAT-DI) at 4 weeks [Up to 11 weeks]

    Computerized Adaptive Test-Depression Inventory (CAT-DI) will be used to assess the depression severity (Achtyes et al., 2015; Gibbons et al., 2012).

  3. Change from Baseline High Frequency Heart Rate Variability (HF-HRV) at 4 weeks. [Up to 11 weeks]

    HRV is an autonomic biomarker of cardiovagal modulation. HRV will be calculated from EKG which will be recorded with EEG co-synchronously.

Other Outcome Measures

  1. Change from Baseline Skin Conductance Response at 4 weeks [Up to 11 weeks]

    Skin conductance is a psychophysiological measure of sympathetic nervous system activity. Skin conductance response (SCR) will be measured with EEG co-synchronously.

  2. Change from Baseline Clinically Relevant Psychological Data at 4 weeks [Up to 11 weeks]

    Clinically Relevant Psychological outcome measures include assessments of mindfulness, self-compassion, interoceptive awareness, interoceptive appreciation, difficulties in emotional regulation, quality of life, gratitude, anxiety, depression, stress, purpose in life, and social connectedness.
