The goal of this fully-remote randomized controlled trial is to test the efficacy of Mindful Steps in facilitating physical activity compared to usual standard of care among 136 patients with COPD and/or HF. The main question it aims to answer is can this intervention promote physical activity as measured by daily step counts in sedentary patients with COPD and/or HF. Participants will be randomized (1:1 ratio) to receive either the Mindful Steps intervention or usual care for 12 months, with both arms receiving a Walking for Health education booklet.
This is a 2-arm parallel remotely delivered RCT. A total of 136 participants with COPD and/or HF will be randomized in a 1:1 ratio to one of 2 arms in a pragmatic design: 1) Mindful Steps multi-modal intervention, or 2) usual care (including an education booklet on walking). Subjects will participate in the intervention for 12 months. Testing will occur at baseline, 3, 6, 12 (end intervention), and 15 months (post-intervention follow up) for all participants. Physical activity as measured by pedometer (i.e., daily step counts) at 12 months is the primary outcome to assess the efficacy of the Mindful Steps intervention. Secondary outcomes include cognitive-behavioral measures that may relate to behavior change in a conceptual model (self-efficacy, intrinsic motivation, mindful awareness/interoception) as well as patient-centered clinical outcomes (HRQL, dyspnea, fatigue, PA engagement, sedentary behavior).

|---|---|---|---|
| Mindful Steps | Experimental | Multi-modal web intervention including: pedometer with individualized step-count goals, motivational and educational content, online community forum, mind-body videos (short themed clips that support walking, plus library of mind-body exercises), online group mind-body exercise classes, star incentive system; educational booklet |
|

| Measure | Description | Time Frame |
|---|---|---|
| Change in physical activity | Daily step counts will be measured as an objective proxy for physical activity using FitBit pedometers (FitBit Inspire 3) | baseline, months 3, 6, 12, and 15 |
| Measure | Description | Time Frame |
|---|---|---|
| Change in self-efficacy | Exercise self-efficacy will be measured using the Self-Efficacy for Exercise Scale and the Self-Efficacy for Managing Chronic Disease Scale. The Self-Efficacy for Exercise Scale a 9-item validated scale; scores range from 9-28, with a higher score meaning more self-efficacy. The Self-Efficacy for Managing Chronic Disease Scale is a 6-item visual analog scale; scores range from 1-10, with a higher score indicating higher self-efficacy. |

Testing will be facilitated by study staff who are blinded to treatment assignment.
| baseline, months 3, 6, 12, and 15 |
| Change in intrinsic motivation | Intrinsic motivation will be measured using the Intrinsic Motivation Inventory. This is a 22-item scale validated with four sub-scales: interest/enjoyment, perceived competence, perceived choice, and pressure/tension. A higher score is better, with a scoring range of 22-154. | baseline, months 3, 6, 12, and 15 |
| Qualitative inquiry | Half-hour semi-structured qualitative interviews guided by study staff will be conducted over video/phone in a random subset of 50 participants at the 6 and 12 month timepoints. | months 6 and 12 |
| Change in disease-specific quality-of-life | Disease-specific quality-of-life will be measured using St. George's Respiratory Questionnaire (SGRQ) and The Minnesota Living with Heart Failure Questionnaire (MLFHQ). The SGRQ is a 50-item instrument developed and validated in COPD and calculates four scores: symptomatology, activity, impacts and an overall metric; scores range from 0-100, with higher scores indicating more limitations. The MLFHQ is a 21-item instrument; total scores range from 0-105, with higher scores indicating poorer quality-of-life. | baseline, months 3, 6, 12, and 15 |
| Change in exercise engagement | Exercise engagement will be measured using the Community Healthy Activities Model Program for Seniors (CHAMPS) Physical Activity Questionnaire. This 41-item self-report questionnaire assesses engagement with physical activity, including frequency and duration, among older adults over the past 4 weeks. Separate scores are derived for physical activities of varying intensities. Frequency and estimated caloric expenditure are calculated per week for each of these physical activity categories, with higher scores indicating greater frequency and duration of exercise. | baseline, months 3, 6, 12, and 15 |
| Change in sedentary behaviors/time | Sedentary behaviors/time will be measured using online weekly exercise logs. These online weekly exercise logs will be used to assess frequency and categorize exercises. | baseline, months 3, 6, 12, and 15 |
| Change in dyspnea | Dyspnea is being measured using the UCSD Shortness of Breath Questionnaire - a 24 item questionnaire using a 6 point Likert scale; scores range from 0-120, with higher scores indicating greater dyspnea. | baseline, months 3, 6, 12, and 15 |
| Change in fatigue | Fatigue will be measured using the The Patient-Reported Outcome Measurement Information System (PROMIS) Fatigue Short Form 7a. Raw scores range from 7-35, and each raw score is translated into a standardized T-score, with higher T-scores representing greater fatigue. | baseline, months 3, 6, 12 and 15 |
| Change in mindful awareness | Mindful awareness will be measures using the Multidimensional Assessment of Interoceptive Awareness, consisting of 37 items (8 domains), each domain scored as the average score on a 6-point Likert. | baseline, months 3, 6, 12 and 15 |
