Brief Summary

This pilot study aims to demonstrate that emotional regulation (ER) is a valuable supplement to a documented and effective group-based lifestyle intervention on cardiovascular disease risk reduction maintenance in a non-clinical population by assessing changes in this primary outcome: Mediterranean diet adherence and these secondary outcomes: average daily steps, METS per week, BMI, blood pressure, physical activity, LDL, HDL, Triglycerides, Hemoglobin A1c, Western Diet Score, ER skills, Healthy Heart Score and eating behavior. This study will include women aged 35-75 and the group intervention will be based on the gold standard Diabetes Prevention Study, integrating the Mediterranean Diet as well as emotional regulation skills based on dialectical behavior therapy. The core intervention will last 3 months with 2 booster sessions will be conducted over 1 month.

Detailed Description

Group lifestyle interventions (LI) have documented efficacy in improving cardiovascular disease (CVD) risk factors, however, many fail to demonstrate outcome maintenance. Existing LIs primarily focus on behavioral regulation, neglecting to address emotional regulation (ER). Difficulty with negative emotions often leads to unhealthy lifestyle recidivism, particularly in women, whereas acquiring ER skills have been found to improve healthy eating and is associated with increased physical activity. The effectiveness of ER as a healthy eating intervention has been documented in individuals with binge eating disorders and obese emotional eaters; however, it has never been utilized in a non-clinical population.

This pilot study aims to demonstrate that emotional regulation (ER) is a valuable supplement to a documented and effective group-based lifestyle intervention on cardiovascular disease risk reduction maintenance in a non-clinical population by assessing changes in this primary outcome: Mediterranean diet adherence and these secondary outcomes: average daily steps, METS per week, BMI, blood pressure, physical activity, LDL, HDL, Triglycerides, Hemoglobin A1c, Western Diet Score, ER skills, Healthy Heart Score and eating behavior. This study will include females and the group intervention will be based on the gold standard Diabetes Prevention Program, integrating the Mediterranean Diet as well as emotional regulation skills based on dialectical behavior therapy. The intervention will take place over 4 months: a weekly core intervention over 3 months time and 2 booster sessions over 1 month time.

Intervention:

Group sessions will focus on adherence to the Mediterranean Diet and increased physical activity. Nutrition content will include diet education, group counseling and social support, food interaction (tasting and cooking), behavioral self-regulation techniques (goal setting, self-monitoring, planning), conscious eating, creating healthy environmental support, and guidance tailored to the target audience. Physical activity will include education, motivation, guidance in starting a routine, and an experiential aerobic exercise class. Participants will be encouraged to exercise at least 150 minutes per week. Physical activity will also be integrated into sessions through a walking program, where participants receive a pedometer, weekly physical activity encouragement and tips, and create weekly step goals. Weekly steps will be tabulated by group leaders and assistants through pedometer measurement.

The emotion regulation skills modules will be modified from the Dialectical Behavior Therapy manual adapted to binge eating disorders (DBT-BED) and other ER sources. These modules will emphasize ER skills that include the ability to identify and label emotions, to recognize their causes and what maintains emotions, the ability to accept and tolerate negative emotions, the skills to provide effective self-support and self-compassion in distressing situations, and the ability to manage situations that elicit negative emotions, as well as re-appraisal skills, which are identified as particularly influential on eating behaviors.

Maintenance preparation sessions will address behavioral change maintenance, obstacle identification and coping skills. The booster session will provide an overview of the intervention and plans for continued outside-intervention support.

Data will be collected at baseline and 2 post intervention follow up points (after the first 4 months and 6 months following).

Control:

There will be a delayed treatment control for this pilot, wherein participants who enlist to the study will be asked complete baseline questionnaires at enlistment date, 4 months later (at the start of the intervention) and then, at the 2 post intervention data points.

Study Groups

Lifestyle Plus Emotional Regulation

The core intervention will last 5 months. Nutrition content: Mediterranean diet education, social support, self-regulation techniques, and environmental support. Physical activity content: education, guidance in starting a routine, and a walking program with pedometers, weekly physical activity tips and step goals. Emotion regulation content: based on Dialectical Behavior Therapy adapted to binge eating disorders and other ER sources, emphasizing identifying emotions, recognizing the causes of emotions, accepting and tolerating negative emotions, effective self-support and self-compassion, and the ability to manage situations that elicit negative emotions, as well as re-appraisal skills, which are identified as particularly influential on eating behaviors.
