The focus of this study is to examine the feasibility, acceptability, and preliminary impact of a 12-week, telephone-delivered, positive psychology (PP)-based health behavior intervention in a group of patients with mild to moderate heart failure (HF), compared to a motivational interviewing- (MI-) based education condition and treatment as usual (TAU).
The investigators are proposing a study that will focus on the implementation of a novel PP-based health behavior intervention that is adapted for patients with HF. The MGH inpatient units, MGH Heart Center, and MGH primary care clinic outpatients will serve as the source of participants for the study, with patients who have a diagnosis of HF serving as potential participants. The investigators will enroll 60 HF patients, who will take part in a 12-week PP-based health behavior intervention. In this project, the investigators hope to do the following: 1. Test a 12-week, telephone-delivered health behavior intervention utilizing PP exercises and systematic goal-setting in a three-arm, randomized, controlled pilot trial in patients with mild to moderate HF (N=60). 2. Determine whether this optimized intervention is feasible in a small cohort of HF patients. 3. Explore potential benefits of the intervention on outcomes of interest (e.g., psychological health, functioning, and health behavior adherence) compared to a motivational interviewing- (MI) based education condition and treatment as usual (TAU). Baseline information about enrolled participants will be obtained from the patients, care providers, and the electronic medical record as required for characterization of our population. This information will include data regarding medical history (history of prior acute coronary syndrome, coronary artery disease, coronary artery bypass graft, congestive HF, hypertension, diabetes mellitus, hyperlipidemia, and current smoking), current medical variables (renal function, left ventricular ejection fraction, NYHA class), medications, and sociodemographic data (age, gender, race/ethnicity, living alone). Participants will undergo two in person visits during which they will meet with study staff in person (or if preferred over the phone). In their first visit, they will answer questionnaires related to psychological and physical health and functioning and will be asked to wear an accelerometer for one week to measure their baseline physical activity. At their second in-person visit, they will be randomized to receive (1) the PP-based health behavior intervention, (2) the MI-based educational condition, or (3) TAU. Participants in the TAU group will not receive any additional intervention but will complete follow-up phone calls at 12 and 24 weeks. Following randomization, participants in the two treatment groups will be provided a treatment manual corresponding with their treatment condition with weekly exercises, along with a copy of the Learning to Live with Heart Failure guide. The appropriate intervention will be introduced, and the first exercise will be assigned. Finally, participants in both treatment groups will receive a personal step counter to use over the course of the study. Following the second in-person visit, participants in the PP-based intervention and MI-based control condition groups will complete twelve 30- to 45-minute 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. At Weeks 12 and 24, a member of the study staff will call participants to repeat the self-report questionnaires that were administered at baseline. At these two time points, participants also will be asked to wear an accelerometer for an additional 7 days to measure physical activity.

Feasibility of the PP-based Health Behavior Intervention
Feasibility will be measured by examining the number of completed exercises for individuals randomized to the Positive Psychology (PP)-based intervention.
Time frame: Change between baseline and 12 weeks
Acceptability of the Exercises
Participants receiving the PP-based health behavior intervention will provide ratings of ease and utility after each exercise, measured on a 10-point Likert scale.
Time frame: 12 weeks
Immediate Impact of the Exercises
Participants receiving the PP-based health behavior intervention will provide ratings of optimism and positive affect, before and after each exercise, measured on a 10-point Likert scale.
Time frame: Weekly, up to 12 weeks
Change in PANAS Scores (Primary Psychological Outcome)
The positive affect items on the Positive and Negative Affect Schedule (PANAS), a well-validated scale used in other intervention trials and in patients with HF, will be used to measure positive affect (Range: 10-50). Change was calculated by subtracting the score at baseline from the score at 12 and 24 weeks. Higher scores indicate higher levels of positive affect.
Time frame: Baseline, 12 weeks, and 24 weeks
Changes in LOT-R Scores
Life Orientation Test-Revised (LOT-R) is a well-validated 6-item instrument used to measure dispositional optimism (Range: 0-24). Change was calculated by subtracting the score at baseline from the score at 12 and 24 weeks. Higher scores indicate higher levels of dispositional optimism.
Time frame: Baseline, 12 weeks, and 24 weeks
Changes in SOM Scores
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
The State Optimism Measure (SOM) will be used to measure state optimism (Range: 7-35). Change was calculated by subtracting the score at baseline from the score at 12 and 24 weeks. Higher scores indicate higher levels of state optimism.
Time frame: Baseline, 12 weeks, and 24 weeks
Changes in HADS-Anxiety Subscale Scores
The Hospital Anxiety and Depression Scale (HADS)-anxiety subscale was be used to measure 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 12 weeks and 24 weeks. Higher scores indicate higher levels of anxiety.
Time frame: Baseline, 12 weeks, and 24 weeks
Change in HADS-Depression Subscale Scores
The Hospital Anxiety and Depression Scale (HADS)-depression subscale was be used to measure depression. 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 12 weeks and 24 weeks. Higher scores indicate higher levels of depression.
Time frame: Baseline, 12 weeks, and 24 weeks
Changes in KCCQ Scores (Primary Functional Outcome)
The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a well-validated questionnaire of health status in HF. The full scale will be used to measure HF-specific health-related QoL (HRQoL), and an eight-question subset of the KCCQ will be used as a measure of HF symptoms (QoL score range: 0-100; total symptom score range: 0-100). Change was calculated by subtracting the score at baseline from the score at 12 weeks and 24 weeks. Higher QoL scores indicate better HF specific health-related QoL, and higher total symptom scores indicate fewer symptoms.
Time frame: Baseline, 12 weeks, and 24 weeks
Changes in SF-12 Scores
The Medical Outcomes Study Short Form-12 (SF-12) will be used to measure quality of life. This is an instrument which has been used in multiple cardiac studies in the past (SF-12 Mental Composite Score and Physical Composite Score Range: 0-100 each). Change was calculated by subtracting the score at baseline from the score at 12 weeks and 24 weeks. Higher scores indicate higher level of health related QoL.
Time frame: Baseline, 12 weeks, and 24 weeks
Changes in MOS SAS Scores
Three Medical Outcomes Study Specific Adherence Scale (MOS SAS) items assessing medication, diet, and exercise, will be measured individually and as a composite score (Range: 3-18). Change was calculated by subtracting the score at baseline from the score at 12 weeks and 24 weeks. Higher scores indicate better adherence to health behaviors.
Time frame: Baseline, 12 weeks, and 24 weeks
Changes in Sodium Intake (as Measured With the SSQ)
The Scored Sodium Questionnaire (SSQ) is a self-report scale that assesses the frequency with which participants consume a variety of sodium-containing foods, ranging from "Rarely or Never Eaten" to "At Least Once Daily." It is used to calculate daily sodium intake (Range: 0-215). Change was calculated by subtracting the score at baseline from the score at 12 weeks and 24 weeks. Higher scores indicate higher sodium intake.
Time frame: Baseline, 12 weeks, and 24 weeks
Changes in Self-Reported Medication Adherence (SRMA)
The Self-Reported Medication Adherence (SRMA) asks what percent of the time (in 10% increments) participants took all of their medications as prescribed in the past week and in the past 2 weeks (Range: 0-100). Change was calculated by subtracting the score at baseline from the score at 10 weeks.
Time frame: Baseline, 12 weeks and 24 weeks
Change in Physical Activity
Assessed by ActiGraph GT3X+ step counters which are validated as measures of physical activity and have been used in numerous studies of physical activity in patients with medical illness. We will measure both number of steps per day (primary physical health outcome). Change scores will be calculated by subtracting the number of steps per day at baseline from number of steps per day at 12 weeks and 24 weeks.
Time frame: Baseline, 12 weeks, and 24 weeks
Change in Moderate to Vigorous Physical Activity
Assessed with ActiGraph GT3X+ step counters, which are validated as measures of physical activity and have been used in numerous studies of physical activity in patients with medical illness. Change was calculated by subtracting the MVPA at baseline from the MVPA at 12 weeks and 24 weeks.
Time frame: Baseline, 12 weeks, and 24 weeks
Feasibility of Actigraph
Feasibility will be measured by examining the number of participants who provide adequate Actigraph data, defined in this study as at least 480 minutes for 5 days, at each time point.
Time frame: Baseline, 12 weeks and 24 weeks
