Metabolic Syndrome
Conditions
Brief summary
Specific Aim #1 (Feasibility; primary aim): To assess the feasibility of the positive psychology (PP)-motivational interviewing (MI) group-based physical activity intervention and outcome assessments in patients with metabolic syndrome (MetS). Hypothesis: The PP exercises and MI-based goal-setting sessions will be feasible: most (≥50%) of participants will complete 6/8 exercises/sessions. Furthermore, we will be able to obtain objective physical activity measurement follow-up data from at least 80% of enrolled participants at 8 weeks. Specific Aim #2 (Acceptability): To assess whether the intervention is acceptable to participants, as measured by ratings provided after each PP and MI exercise. Hypothesis: The intervention will be acceptable: participants will rate each PP and MI exercise with a mean score of at least 7 out of 10 on ratings of ease of completion and helpfulness. Specific Aim #3 (Outcomes): To assess whether this preliminary intervention appears to result in improvement of physical activity, related health behaviors (sedentary time, diet quality), and psychological well-being (optimism, positive affect, anxiety, depression). Hypothesis: The intervention will lead to improvements in physical activity, related health behaviors, optimism and positive affect, and reductions in depression and anxiety at 8 weeks compared to baseline.
Detailed description
In this proof-of-concept study, investigators will run two 8-week PP-MI groups (complete n=8 each, n=16 total) for primary care patients with MetS. Investigators will use ratings of feasibility and acceptability for each of the sessions and obtain objective physical activity measures pre- and post- group. Investigators will also obtain questionnaire-based information related to health behavior adherence and psychological and physical health to ensure the feasibility of these methods prior to further testing. Investigators may gather exit interview data to assess participant liking, utility, and additional needs, to allow for further refinement of the intervention. Baseline information about enrolled participants will be obtained from the patients, care providers, and the electronic medical record as required for characterization of the population. This information will include medical data related to MetS (e.g., blood sugar, blood pressure, body mass index, triglycerides, cholesterol), current medications, and sociodemographic data (age, gender, race/ethnicity, education, marital status). Participants will attend 90-minute groups sessions that will be held at two primary care clinics (MGH Healthcare Centers). The overall structure of each session will be: 30 minutes for positive psychology exercise review/discussion, 30 minutes for physical activity goal setting, education, and discussion, and 30 minutes for a group walk or indoor exercises in inclement weather. Participants will be asked to wear an Actigraph GT3x+ accelerometer for 1 week at baseline and 1 week at follow-up to assess the feasibility of doing so. Accelerometers such as this one are considered to be the standard for measuring habitual physical activity. They are pedometer-size devices that attach to a belt and are worn at the waist. Participants will also be given a Fitbit Zip to keep, which they will be asked to wear daily for the duration of the study in order to track their activity (steps). Upon beginning the groups, participants will be provided with a treatment manual with weekly PP exercises, information about the importance of physical activity and related health behaviors, and how to set goals to improve these behaviors. The PI will lead all groups. For the first session, in the PP portion, participants will discuss and be assigned the first exercise- gratitude for positive events- and will be instructed to complete the PP exercise during the next week. Prior to completing the exercise, participants will be asked to rate their current levels of happiness and optimism. Immediately after completing the exercise, participants will rate the ease of exercise completion, overall utility of the exercise, and their current levels of happiness and optimism, all using 10-point Likert scales. In the first goal-setting session, we will discuss the importance of physical activity in MetS. Participants will be given a Fitbit Zip to keep, which they will use to track the number of steps they take each day, for the duration of the study. Investigators will review instructions for use and set a goal for monitoring their baseline physical activity over the next week. Fitbits will not be used as an outcome measure but as a tool that participants can use to monitor their activity and set goals. Finally, the last 30 minutes will be spent doing a group walk around the local clinic neighborhood. All group walks and exercises will be done at a pace comfortable for participants. Participants will be asked to complete the 8 total weekly PP exercises, set physical activity goals, and attend as many group sessions as they can. All sessions will include (a) a review and discussion of the past week's PP exercise, (b) a discussion of the rationale of the next week's PP exercise using the PP manual, and (c) assignment of the next week's PP exercise. For the goal-setting/MI portion, participants will (a) review their goals and steps from the prior week, (b) discuss techniques for improving physical activity (e.g., monitoring physical activity, taking standing breaks), and (c) set goals for the next week. The exercises and content for both PP and MI will be assigned in the same order for all participants receiving them. Immediately after the week 8 session, investigators will distribute the same self-report questionnaires that were administered at baseline (before week 1). The Actigraphs will then be collected at this point and the data will be uploaded to assess for valid wear time. If participants have not worn them for enough time (\>4 days), investigators will send it home with them and ask them to re-wear it and mail it back.

The Hospital Anxiety and Depression Scale will be used to measure depression and anxiety. This is a well-validated scale with few somatic symptom items that can confound mood/anxiety assessment in medically-ill patients.(Range: 0-21). Change was calculated by subtracting the score at baseline from the score at 8 weeks. Higher scores indicate worse outcome (i.e. greater levels of depression).

|---|---|---|---|---|
| Intervention Arm: PP-MI | Change in HADS-D Scores | Baseline | 4.6 score on a scale | Standard Deviation 2.9 |

Changes in Barriers to Being Active Quiz- Lack of Time Scores
The BBAQ is a 21-item measure, published by the US Centers for Disease Control and Prevention (CDC), assessing the following barriers to physical activity: 1) lack of time, 2) social influence, 3) lack of energy, 4) lack of willpower, 5) fear of injury, 6) lack of skill, and 7) lack of resources (eg, recreational facilities, exercise equipment). Each domain contains 3 items, with a total score range of 0 to 63. Respondents rate the degree of activity interference on a 4-point scale, ranging from 0 = very unlikely to 3 = very likely. This outcome explores lack of time category (range of 0-9), and we calculated the change in score from baseline to 8 weeks.
Time frame: Baseline and 8 weeks

Changes in National Cancer Institute's Percentage Energy From Fat Screener Scores
The National Cancer Institute's Percentage Energy from Fat Screen is a brief questionnaire that estimates people's typical percentage of energy derived from eating common fat-containing foods, as fat content is related to metabolic syndrome progression. The questionnaire converts an individual's responses to an estimate of that individual's percentage energy from fat. Higher scores indicate higher fat consumption.
Time frame: Change in number of times fat is consumed per day from Baseline to 8 weeks
