简要总结
This study will adapt a physical activity lifestyle intervention to emerging adult congenital heart disease (CHD) survivors with the primary goal of increasing physical activity levels.
The study will be split into 2 phases. In Phase 1, participants will be asked to complete questionnaires, wear an accelerometer around the waist for 7 days, and undergo an exercise stress test. The accelerometer and exercise stress test will be used to determine whether participants are eligible to be randomized for the intervention study. In Phase 2, participants will be randomized to one of two conditions: 1) receiving a physical activity tracker (a Fitbit) or 2) receiving a Fitbit AND engaging in videoconferencing sessions with a physical activity coach. During Phase 2, participants will also be asked to complete 3 assessments (weeks 9 and 22, and a 6-month follow-up). The week 9 assessment will consist of completing questionnaires and wearing an accelerometer for 7 days. Week 22 will be similar to week 9 with the addition of a final exercise stress test. The 6-month follow-up will mirror the week 9 assessment.
Participants who are randomized to the videoconferencing condition will be asked to meet with a physical activity coach 8 times over the course of 20 weeks. Coaches will help participants to (1) change attitudes toward physical activity, (2) increase perception of others' approval of physical activity (e.g., family members, peers), and (3) increase participants' perceived control by troubleshooting barriers and increasing efficacy for physical activity. Coaches will use the Fitbit to facilitate self-monitoring and goal setting. Participants in the intervention arm will be asked to participate in a focus group at the conclusion of the study to share their experiences.

盲法说明
Investigator, research assistants, coaches (interventionists), and participants do not know which condition a participant is in until the condition is revealed (opening an envelope with the condition listed) after the participant consents to Phase 2. Envelopes with the conditions were prepared by the study statistician.
