Motivational Interviewing & Clinician Centered Interviewing on Cardiac Rehab

Study Overview
=================
Brief Summary
-----------------
The purpose of this project is to examine the differences in outpatient cardiac rehab (OPCR) core component outcomes on different intervention conditions. Conditions include traditional OPCR (control), OPCR + motivational interviewing (MI) and OPCR + Clinician centered interviews.

Detailed Description
-----------------
Participants who are beginning a OPCR program at a local hospital are eligible for the program. During the standard admission procedures, eligible participants will be provided with a consent from and asked to participate in the study. Participants who provide consent will complete their admission packet. The standard admission packet includes: the Outpatient Fall Assessment Risk, Patient Health Questionnaire (PHQ-9),the Dartmouth Quality of Life, and the Rate Your Plate. In addition participants will complete three additional surveys: the Intrinsic Motivation Inventory (IMI), the FPS, (FACES Pain Scale), and the Brief Resilience Scale (BRS). During their second appointment participants will complete the standard 6 minute walk test which is scheduled at their convenience and the grip strength. Participants will then be randomly assigned to the traditional OPCR, the OPCR + MI, or the OPCR - Clinician centered. Post-testing will include all baseline information as well as information from patients charts (lipid profile, HbA1c, risk factors and family history). Analysis will determine differences in core outcomes between the three groups.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Participants are randomly assigned to one of three groups.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Traditional OPCR<br>Those who are in the traditional group will discuss topics like medication adherence, physical activity questions, or eating habits without a clear from of autonomy or nonautonomy basis as is currently completed in OPCR. This will occur in a face to face format. | Behavioral: Motivational Interviewing<br>* Participants will participate in three different communication styles to determine the effect of MI on cardiac rehab outcome measures.<br>|
| Experimental: OPCR + MI<br>The MI group will be consistent with the spirit of MI and utilize a high autonomy communication style to provide support for behavior change across multiple behaviors. This will occur in a face to face format. | Behavioral: Motivational Interviewing<br>* Participants will participate in three different communication styles to determine the effect of MI on cardiac rehab outcome measures.<br>|
| Experimental: OPCR + Clinician centered<br>The OPCR + CC group will participate in low-autonomy face to face interviews. Meaning the communication style will be clinician centered, providing goals to the participants without valuing their input. | Behavioral: Motivational Interviewing<br>* Participants will participate in three different communication styles to determine the effect of MI on cardiac rehab outcome measures.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Adherence to CR | Differences in the number of sessions attended between groups | 12 weeks | 
| 6-minute walk | Changes in the distance traveled during a 6-minute walk | 12 weeks | 
| Rate my plate | Changes in heart healthy diet | 12 weeks | 
| Dartmouth Quality of Life index | Changes in Dartmouth Quality of Life Index. Range is 9-45. Higher score indicates lower quality of life. | 12 weeks |
