Brief Summary: 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).

Detailed Description: 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.

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 50

Inclusion Criteria

Adult patients with NYHA class I, II, or III HF admitted to an MGH inpatient unit or outpatients at the MGH Heart Center or MGH-affiliated primary care clinic. Patients with NYHA class IV HF have ongoing HF symptoms at rest, making it difficult for them to increase physical activity and other health behaviors; therefore, they will not be included. HF diagnosis will be confirmed via chart review and with the patient's treatment team as needed.
Suboptimal adherence to health behaviors. This will be defined as a total score of ≤15 on three Medical Outcomes Study Specific Adherence Scale (MOS) items regarding diet/exercise/medications. The MOS has been used in multiple prior studies assessing adherence in cardiac patients, including our own studies in this population. This threshold score on the MOS will ensure that all participants will have the potential to improve their health behaviors.

Exclusion Criteria

Cognitive deficits impeding a participant's ability to provide informed consent or participate, assessed via a 6-item cognitive test that is sensitive and specific for screening for cognitive impairment in research participants.
Medical conditions precluding interviews or likely to lead to death within 6 months.
Inability to speak English, inability to read or write, inability to walk, or lack of a telephone.

Arm && Interventions

Group	Intervention	Description
PP-based health behavior intervention	PP-based health behavior intervention	Participants will undergo a 12-week, Positive Psychology (PP)-based health behavior intervention. Each weekly session will include (a) a review of the week's PP exercise, (b) a discussion of the rationale of the next week's PP exercise through a guided review of the PP manual, and (c) assignment of the next week's PP exercise. Additionally for the goal-setting portion, participants will (a) review their goals and 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.
MI-based educational control condition	MI-based educational control condition	Participants will undergo 12 weekly phone sessions to learn about a different health behavior topic related to cardiac health. This Motivational Interviewing (MI)-based educational control condition will introduce these participants to motivational interviewing topics in concert with the health behavior education topics.

Primary Outcome Measures

Name	Time	Method
Feasibility of the PP-based Health Behavior Intervention	Change between baseline and 12 weeks	Feasibility will be measured by examining the number of completed exercises for individuals randomized to the Positive Psychology (PP)-based intervention.

Secondary Outcome Measures

Name	Time	Method
Changes in SOM Scores	Baseline, 12 weeks, and 24 weeks	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.
Changes in KCCQ Scores (Primary Functional Outcome)	Baseline, 12 weeks, and 24 weeks	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.
Changes in SF-12 Scores	Baseline, 12 weeks, and 24 weeks	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.
Acceptability of the Exercises	12 weeks	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.
Change in PANAS Scores (Primary Psychological Outcome)	Baseline, 12 weeks, and 24 weeks	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.
Changes in MOS SAS Scores	Baseline, 12 weeks, and 24 weeks	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.
Changes in HADS-Anxiety Subscale Scores	Baseline, 12 weeks, and 24 weeks	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.
Immediate Impact of the Exercises	Weekly, up to 12 weeks	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.
Changes in LOT-R Scores	Baseline, 12 weeks, and 24 weeks	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.
Change in HADS-Depression Subscale Scores	Baseline, 12 weeks, and 24 weeks	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.
Changes in Self-Reported Medication Adherence (SRMA)	Baseline, 12 weeks and 24 weeks	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.
Changes in Sodium Intake (as Measured With the SSQ)	Baseline, 12 weeks, and 24 weeks	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.
Feasibility of Actigraph	Baseline, 12 weeks and 24 weeks	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.
Change in Moderate to Vigorous Physical Activity	Baseline, 12 weeks, and 24 weeks	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.
Change in Physical Activity	Baseline, 12 weeks, and 24 weeks	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.
