Promoting Well-being and Health in Heart Failure

Study Overview
=================
Brief Summary
-----------------
The focus of this study is to test the efficacy of a 12-week, phone-delivered Positive Psychology-Motivational Interviewing (PP-MI) intervention, with additional twice weekly PP and health behavior text messages for a total of 24 weeks (with interactive, algorithm-driven, goal-focused text messages in the final 12 weeks), compared to an attention-matched MI-based educational condition, in a randomized trial (NIH Stage II) of 280 patients with New York Heart Association class I-III Heart Failure (HF).

Detailed Description
-----------------
The investigators are proposing a study that will focus on testing the efficacy of a Positive Psychology-Motivational Interviewing (PP-MI) intervention, with additional twice weekly PP and health behavior text messages for a total of 24 weeks (with interactive, algorithm-driven, goal-focused text messages in the final 12 weeks) in patients with New York Heart Association class I-III HF. The investigators will enroll 280 HF patients, who will take part in a 12-week (with 24 weeks of supplemental text messages) health behavior intervention. In this project, the investigators hope to do the following: Examine the efficacy of a 12-week, phone-delivered PP-MI intervention for individuals with heart failure (HF) on health behavior adherence at 12 weeks (primary time point), 24 weeks, and 48 weeks. Assess the intervention's impact on psychological outcomes, health-related quality of life (HRQoL), HF-specific quality of life, HF symptoms, and function. Explore the intervention's impact on markers of cardiovascular health (e.g., blood pressure), as well as major adverse cardiac events, HF hospitalizations, and mortality. Participants will undergo two visits (in-person or virtual) during which they will meet with study staff. During the first visit, participants will provide informed consent, answer questionnaires related to psychological and physical health and functioning, have their blood pressure and weight measured, and be asked to monitor their physical activity (using an accelerometer) for one week and medication adherence (using an electronic pill bottle) for two weeks. Participants will be given a urine collection container and asked to provide a urine sample within 4 hours of their first void and before eating breakfast on the day of Visit 2. At the second visit, the urine sample will be collected, and upon confirmation of adequate physical activity and medication adherence data, participants will be randomized to receive the PP-MI intervention or the MI-alone intervention. Following randomization, all participants will be provided a treatment manual corresponding with their treatment condition, a Fitbit activity tracker, and other treatment materials. The appropriate intervention will be introduced, and the first exercise will be assigned. Following the second visit, participants in both treatment conditions will complete twelve weekly phone sessions with a study trainer. The phone sessions primarily will include a review of the prior week's session content and a discussion of the rationale and assignment of the next week's exercise/assignment. Participants in both treatment conditions will receive twice weekly text messages throughout the intervention (Weeks 1-12) and initial follow-up period (Weeks 13-24). During the intervention, these messages will provide information about the PP activity (PP-MI group) and health behavior goal (both groups) discussed that week. During Weeks 13-24, participants in the PP-MI condition will engage with twice weekly, automated, interactive text messages related to PP and health behavior goals. Individuals in the MI-alone group will receive identical messages related to setting health behavior goals as the PP-MI participants and will additionally receive a fixed test message providing education about health behavior adherence. At Weeks 12, 24, and 48, participants will complete follow-up visits. One week prior to these visits, participants will be mailed an accelerometer and will wear it until their study visit. They will also be sent a container for urine collection, which they will bring to their follow-up visit. During these study visits, participants will be asked to answer questionnaires related to psychological and physical health and functioning, have their blood pressure, weight, and waist circumference measured, will perform a 6 minute walk test, and be asked about cardiovascular outcomes, including hospitalizations, cardiovascular procedures, and cardiac-specific hospitalizations. Finally, participants will complete phone sessions every 6 months until study end to inquire about hospitalizations and adverse cardiac events.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: PP-MI Intervention<br>Participants will receive a 12-week, Positive Psychology-Motivational Interviewing (PP-MI) intervention. Each week, participants will complete a PP activity and work towards one or more health behavior goals, then complete a phone session with a study trainer. Each weekly session will include PP and goal setting portions. In the PP portion, a study trainer will (a) review the week's PP exercise, (b) discuss the rationale of the next week's PP exercise through a guided review of the PP-MI manual, and (c) assign the next week's PP exercise. Additionally for the goal-setting portion, the trainer will (a) review their goals and health behaviors from the prior week, (b) discuss techniques for improving health behavior adherence (e.g., monitoring physical activity, reading nutrition labels), and (c) set goals for the next week. Finally, participants will receive supplemental text messages throughout the 12 weeks of the intervention and during the initial follow-up period (Week 13-24). | Behavioral: PP-MI Intervention<br>* The 12-week PP-MI intervention focuses on enhancing well-being (through PP) and promoting adherence to physical activity, diet, and medications (through MI). Each week, participants will complete a PP activity and work towards one or more health behavior goals, then complete a phone session with a study trainer. The PP portion of the program will focus on the cultivation of well-being through the performance of easy-to complete activities (e.g., using a strength in a new way) and review of the positive feelings they generate. The MI portion of the program will focus on assisting participants to monitor health behavior adherence, resolve ambivalence to behavior change, set realistic health behavior goals, problem-solve barriers, and identify resources to complete behavior change. Finally, participants will receive twice weekly text messages (for 24 weeks) to encourage completion of PP activities and engagement in health behaviors.<br>|
| Active Comparator: MI-alone Intervention<br>This condition will mirror the MI component of the PP-MI intervention. During the first three sessions, participants will learn about the causes and types of HF, risk factors for cardiovascular disease, and methods for monitoring risk factors and symptoms. Then participants will complete nine sessions related to physical activity, a low sodium diet, and medication adherence. Weekly tasks (e.g., brainstorming barriers) will be assigned, completed between calls, and reviewed at the following call. Finally, participants will receive supplemental text messages throughout the 12 weeks of the intervention and during the initial follow-up period (Week 13-24). | Behavioral: MI-alone Intervention<br>* The time- and attention-matched MI-alone intervention focuses on providing education about heart failure (HF) and promoting adherence to physical activity, diet, and medications. Each week, participants will independently complete an activity related to HF education or adherence to a health behavior, then complete a phone session with a study trainer. HF educational topics will include the causes and types of HF, risk factors for cardiovascular disease, methods for monitoring risk factors and symptoms, and the importance of adherence to physical activity, diet, and medications. For each health behavior, study trainers will assist participants to monitor adherence, identify realistic behavior goals, problem-solve barriers, and identify resources to complete behavior change. Finally, participants will receive twice weekly text messages (for 24 weeks) that provide education and encourage engagement in health behaviors.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Health behavior adherence | Composite score of overall activity (measured by accelerometer in steps/day), sodium excretion (urine sodium in mEq/day), and medication adherence (Medication Event Monitoring System [MEMS] electronic pill bottle). This composite score will be created by calculating z scores for each individual outcome measure and then averaging them for each participant at each time point. | Baseline, 12 Weeks, 24 Weeks, 48 Weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Physical activity (in steps/day) | Physical activity (steps) will be measured via an accelerometer. We will use established accelerometer protocols to measure the mean number of steps taken per day at each time point. | Measured for 7 days at baseline, 12 weeks, 24 weeks, and 48 weeks | 
| Objective medication adherence (Medication Event Monitoring System [MEMS] pill bottles) | Medication adherence will be measured using MEMS electronic pill bottles. Participants will receive a MEMS pill bottle at the initial study visit and will be asked to put one cardiac medication (loop diuretic, ACE inhibitor, beta blocker, or aspirin, in that order) in the bottle and then use it throughout the study period (48 weeks). Adherence will be measured by the percentage of appropriate bottle openings over a 2-week period at baseline and the follow-up time points. | Measured for 14 days at baseline, 12 weeks, 24 weeks, and 48 weeks | 
| Sodium Excretion (mEq/day) | Objective sodium intake will be assessed through the measurement of urinary sodium excretion. Participants will provide a sample of their second voiding of the day, and from this sample, urine sodium and urine creatinine will be measured. | Baseline, 12 weeks, 24 weeks, 48 weeks | 
| Positive Affect (Positive and Negative Affect Schedule [PANAS] positive affect items) | Positive affect will be measured using the 10 positive affect items from the PANAS, a well-validated scale used in numerous other behavioral intervention trials. | Baseline, 12 weeks, 24 weeks, 48 weeks | 
| Physical Function (PROMIS 20-item Physical Function Short Form [PF-20]) | The PROMIS 20-item short form (PF-20) will be used to assess physical function. | Baseline, 12 weeks, 24 weeks, 48 weeks |
