MGH Cardiac Psychiatry Research Program

Overview

The MGH Cardiac Psychiatry Research program’s work focuses on the connections between mental health, behavior, and medical health in patients with heart disease and other chronic medical conditions. Our research focuses on developing innovative, remotely delivered treatments in three areas:

Promoting well-being and engagement in healthy behaviors, like physical activity.

Positive psychological states, like optimism, positive affect, and self-efficacy, are associated with improved health and with greater engagement in healthy behaviors, such as physical activity and a healthy diet. Based on this idea, our team has developed several remotely delivered interventions to promote well-being and engagement in healthy behaviors in individuals with medical problems, such as type 2 diabetes and heart failure.

We are performing ongoing studies to determine whether phone-delivered versions of these programs may affect biology, health behaviors, and key cardiac outcomes. We are also working to adapt these positive psychological interventions to patients with other medical populations, such as those with metabolic syndrome, irritable bowel syndrome, or cancer, and in those who have undergone weight loss surgery.

In addition to our phone-delivered programs, we have developed programs that utilize other methods of communication, including text messages, podcasts, and artificial intelligence-based messaging, to deliver content to promote well-being and engagement in healthy behaviors.

Identifying and treating depression and anxiety disorders in individuals with cardiovascular disease.

Depression and anxiety have been identified as risk factors for poor cardiac outcomes and death, independent of traditional cardiac risk factors such as high blood pressure, smoking or diabetes. Unfortunately, depression and anxiety go unrecognized and untreated in the vast majority of patients with heart disease, despite the existence of safe and effective treatment. We have performed two randomized trials of “collaborative care” interventions for individuals with heart disease and depression or anxiety disorders. These programs were associated with improvements in depressive symptoms, function, and quality of life.

Optimizing mental and physical health prior to surgery.

Major surgical procedures can be lifesaving but often carry risks of complications. Both psychological and behavioral factors can increase the risk of developing complications following surgery. We are developing innovative, multidisciplinary programs to better prepare individuals mentally and physically to undergo surgery, with the goal of promoting a smoother recovery following their surgical procedures.

In all of the programs we develop, our goal is to help people to live happier and healthier lives.

Research Projects

Boosting Emotional Well-being and Happiness in Outpatients Living with Diabetes (BEHOLD)

A novel psychological-behavioral intervention to promote physical activity in type 2 diabetes; National Institute of Diabetes and Digestive and Kidney Diseases (1R01DK133185)

This is a randomized controlled trial (goal N=280) to test the efficacy of an 8-week, phone-based, positive psychology-motivational interviewing intervention (BEHOLD) to promote physical activity in patients with type 2 diabetes. The BEHOLD program will be compared to a motivational interviewing based educational condition, with a primary outcome of moderate to vigorous physical activity. Principal Investigator (PI): Jeff Huffman, M.D.

Positive Emotions after Acute Coronary Events (PEACE V)

A novel psychological-behavioral intervention to promote physical activity in patients with acute coronary syndrome; National Heart Lung and Blood Institute (1R01HL113272)

This is a randomized controlled trial (goal N=280) to test the efficacy of a 12-week, phone-based, positive psychology-motivational interviewing intervention (PEACE) to promote physical activity in patients with acute coronary syndrome (unstable angina or myocardial infarction). The PEACE program will be compared to treatment as usual, with a primary outcome of moderate to vigorous physical activity. Principal Investigator (PI): Jeff Huffman, M.D.

Reach for Health: Researching Emotions and Cardiac Health

A Novel Behavioral Intervention to Promote Adherence in Heart Failure; National Heart, Lung, and Blood Institute (1R01HL155301)

This is a randomized trial (goal N=280) to examine the efficacy of a 12-week, phone-delivered, combined positive psychology-motivational interviewing intervention (“Reach for Health”) to promote health behavior adherence in patients with heart failure. The Reach for Health program will be compared to a motivational interviewing-based control condition, and the primary outcome will be a measure consisting of physical activity, sodium excretion, and medication adherence. Principal Investigator (PI): Christopher Celano, M.D.

WISH 2.0 Pilot Randomized Controlled Trial

A Positive Psychology Intervention for Irritable Bowel Syndrome; National Institute of Diabetes and Digestive and Kidney Diseases (K23DK138875)

This study is a pilot, randomized controlled trial (goal N=50) to evaluate the feasibility, acceptability, preliminary effects, and candidate gut-brain mechanisms of a novel, 9-week, phone-based behavioral health intervention for irritable bowel syndrome (IBS). Principal Investigator (PI): Elizabeth Madva, M.D.

GOALS-M: Adapting a positive emotion-based physical activity intervention for individuals taking incretin-based medications for weight loss

This study is a single-arm proof-of-concept trial (N=19) designed to refine and test initial feasibility and acceptability of GOALS-M, a physical activity intervention for individuals taking incretin-based medications for weight loss. The 10-week phone-based intervention uses positive psychological and behavioral tools to increase positive affect and physical activity.  Principal Investigator (PI): Emily Feig, Ph.D.

Developing Resiliency using AI-based Messaging: The DREAM pilot study (DREAM)

This randomized, controlled pilot trial (goal N=20) aims to examine the feasibility, acceptability, and preliminary efficacy of the DREAM program, an 8- week, interactive, message-based intervention to promote physical activity and wellbeing in adults with type 2 diabetes. In the program, participants will complete positive psychology and motivational interviewing activities during weekly messaging sessions along with a mid-week check-in.  Principal Investigator (PI): Christopher Celano, M.D.

Prehabilitation for aortic aneurysm surgery: Proof-of-concept trial (Ready for Recovery)

This is a single arm, proof-of-concept trial (goal N=10) to examine the feasibility, acceptability, and preliminary efficacy of the Ready for Recovery program, a 6-week, multicomponent, phone-delivered prehabilitation intervention for individuals undergoing elective aortic aneurysm repair. In Ready for Recovery, a multidisciplinary team screens individuals awaiting surgery for risk factors for post-surgical complications and then collaboratively develops a tailored prehabilitation plan to optimize medical and psychological status prior to surgery. Principal Investigator (PI): Christopher Celano, M.D.

Move with Meaning Pilot Trial

A text- and audio-based intervention to promote physical activity in midlife

This is a randomized, wait-list controlled pilot trial (goal N=30) to examine the feasibility, acceptability, and preliminary efficacy of Move with Meaning, an 8-week text message- and audio-based intervention to promote physical activity in 30 midlife adults with low physical activity. Each week, participants will listen to a 20-minute audio session that provides instruction and encouragement related to physical activity and set a weekly goal through interactive text messages. Principal Investigator (PI): Christopher Celano, M.D.

Recently Completed

Gaining Optimism After Weight Loss Surgery (GOALS)

Randomized Controlled Trial of a Positive Psychology-based Intervention to Increase Physical Activity After Bariatric Surgery ; National Institutes of Health: National Heart, Lung, and Blood Institute (K23HL148017)

This study aimed to increase physical activity and psychological well-being in adults who have recently had metabolic and bariatric surgery. We adapted a positive psychology-motivational interviewing telephone counseling intervention for the needs of this population via qualitative interviews and a proof-of-concept study. We then tested the intervention in a pilot randomized controlled trial to examine feasibility, acceptability, and preliminary efficacy on physical activity, positive affect, and other outcomes in adults who recently had metabolic and bariatric surgery.
