Healthy Hearts Healthy Minds

Healthy Hearts Healthy Minds: An Overview Individuals with depression are four times more likely to die from coronary heart disease than someone who does not have depression. At the same time, the risk of having a heart attack with depression is double that of individuals who do not have depression. Exercise, improves both depression and risk factors for heart disease; yet, most Americans do not exercise regularly, especially those with depression and/or heart disease. This study is important to these individuals as most of them want to exercise, but have difficulty finding the motivation and energy to do so, which has a substantially negative impact on their physical and mental health. This study will compare two empirically supported treatments designed to help individuals with a mood disorder at risk or with heart disease to increase their physical activity as objectively measured by a Fitbit (which we will provide to participants at no cost). This new study, focused on getting people moving, is funded by the Patient Centered Outcome Research Institute (PCORI) and involves 2 Patient Powered Research Networks (PPRNs) known as the MoodNetwork and the Health eHeart Alliance. With the help of patients across the country the Healthy Hearts Healthy Minds study team aims to be able to study the best method to get people to be more physically active - making them happier and healthier in the process. What is the purpose of the study? Healthy Hearts Healthy Minds aims to compare two kinds of empirically supported treatment programs to see which is most effective at motivating people to be more physically active and increasing well-being: an online, standard, eight-week mindfulness training and an online, eight-session "cognitive-behavioral" training. The study may also tell us what groups of people do better with one or the other program. How does the study work? 500 participants will be recruited from the MoodNetwork and the Health eHeart Alliance. They will be randomly assigned to either the mindfulness training, the cognitive-behavioral training, or a control group. Participants, regardless of group assignment, will receive a Fitbit Charge II at no cost. All participants will fill out standard well-being and safety assessments every other week for eight weeks to see how they are doing. Participants will also do follow-up assessments after sixteen weeks has elapsed since starting the study. All sessions and assessments will be done online. You may qualify if: * You are physically active less than 150 minutes per week * Have a body mass index (BMI) greater than 25kg/m2 * You possess an internet enabled device (e.g. smartphone, tablet/iPad, or desktop) with the Fitbit app and a registered personal account with Fitbit What does participation involve? * Wearing a FitBit Charge II throughout the duration of the 16 week study * Filling out questionnaires via a secure, online system * Potentially participating in additional weekly program sessions for 8 weeks, depending on which program you are assigned to.
