简要总结
The study has two aims: (1) to develop and examine the acceptability of the technological and theoretical frameworks of MAP to Health and (2) to determine whether MAP to Health is related to changes in theoretically identified mechanisms of behavior change (meaning salience, basic psychological needs satisfaction, and internal motivation). In an exploratory aim, the study will assess how the intervention and mechanisms of change are related to changes in physical activity. Participants will be adults in midlife (ages 40-64) who are insufficiently active, are interested in increasing physical activity, do not have contraindications to engaging in physical activity, and are patients in a large healthcare system in the Midwest.

研究组 & 干预措施
Intervention development and testing
Phase 1 participants (N=12) will complete the MAP to Health online interview and rate the ease of use, usefulness, intention to use, and theoretical fidelity of the intervention.
Phase 2 participants (N=35) will participate in a proof-of-concept pilot trial via a double-pretest single group design. Participants will complete a 4-week pretest monitoring period and an 8-week pilot trial of the intervention, with assessments of Self-Determination Theory mechanisms and meaning salience at pretest (-4 weeks), baseline (0 weeks), midpoint (4 weeks) and posttest (8 weeks). In addition, participants will wear accelerometers to assess physical activity during the 12 week period.

结局指标
主要结局
Meaning Salience
时间窗: 12 weeks
The Meaning Awareness Scale is a 6-item self-report measure that assesses meaning salience. Participants rate the extent to which they were aware of meaning over the past day (e.g, "I was aware of the meaning in my life" on a 7-point Likert type scale ranging from 1 (rarely) to 7 (very often). Items are averaged for a total score (range, 1-7). Participants complete the scale on three random days during each of the four assessment periods and total scores are averaged across those three days. A higher score signifies greater meaning salience, a better outcome.
Basic Psychological Needs Satisfaction
时间窗: 12 weeks
The Psychological Needs Satisfaction in Exercise Scale is a self-report measure used to assess participants' satisfaction of three basic psychological needs (autonomy, competence, and relatedness) in exercise. The scale has 18 items that participants rate on a 6-point Likert-type scale ranging from 1 (false) to 6 (true). Items are averaged within each subscale (autonomy, competence, and relatedness) with possible scores ranging from 1-6. Higher scores indicate greater satisfaction of autonomy, competence and relatedness, a better outcome.
Technology Acceptance
时间窗: within 1 week post-intervention
Participants answered 10 questions rating the extent to which they found the MAP to Health intervention easy to use (4 items) and useful (4-items) and their intentions to use the intervention in the future (2 items). Survey questions were based on previous research and modified for the purposes of this study. Participants rated each item on a scale from 1 (strongly disagree) to 5 (strongly agree). Items were averaged within each subscale, with possible total scores ranging from 1-5. A higher score represents greater technology acceptance, a better outcome.
Autonomous Motivation
时间窗: 12 weeks
• Autonomous motivation was measured using the Behavioral Regulations in Exercise Questionnaire, version 4. The 28-item self-report measure assesses motivations for exercise on the self-determination theory continuum. There are 7 subscales with 4 items each (intrinsic, integrated, identified, introjected - approach, introjected - avoidance, external, and amotivation). Items are summed within each subscale (total score range, 4-28). The subscales were combined using a bifurcation approach, where subscale scores were averaged into two subscales: autonomous (intrinsic, integrated, and identified, total score range 4-28) and controlled motivation (introjected-approach, introjected - avoidance, and external, total score range, 4-28). Higher scores on the autonomous subscale indicate greater internalized motivation, a positive outcome, whereas higher scores on the controlled subscale indicates greater external motivation, a negative outcome.
