简要总结
During the initial months of the COVID-19 pandemic, physical activity (PA) engagement levels declined worldwide. Despite the overwhelming adoption of wearable fitness tracker (WFT) devices, it continues to be unclear as to their effect on PA engagement or PA motivation. Building on past research, we hypothesized that combining a WFT with a known impactful intervention, motivational interviewing (MI) would positively influence both self-determination theory (SDT) motivation and PA during an unprecedented global emergency.
A four-group randomized controlled study was conducted amongst 40 inactive adults over a 12-week period during the COVID-19 pandemic. One group (WFT, n = 10) received a wearable fitness tracker, a second (MI, n=10) received bi-weekly MI sessions, a third (WFT+, n=10) received both, and a fourth (Education, n=10) received basic PA education. Outcome measures for motivation and PA were measured though an online survey before and after the 12-week period.

结局指标
主要结局
Change in Motivation From Baseline at 12 Weeks.
时间窗: Baseline and at 12 weeks.
Changes in motivation for physical activity as described by the self-determination theory was assessed using the Behavioral Regulation in Exercise Questionnaire, v3 (BREQ-3) and the Basic Psychological Needs in Exercise Scale (BPNS). The BREQ-3 uses four survey items per motivational subtype (Amotivation, External, Introjected, Identified, and Integrated Regulation, and Intrinsic Motivation). The BPNS uses three of four items per psychological need (Autonomy, Competence, and Relatedness) The raw scores per subtype or need are averaged for one subtype and need score per participant. The scale ranges from 0 (does not apply to me) to 4 (applies to me very much). Therefore, subtype or need score closer to ) indicate low levels of that subtype whereas scores closer to 4 indicate higher levels of that subtype or need.
Change in Moderate to Vigorous Physical Activity From Baseline at 12 Weeks.
时间窗: Baseline and at 12 weeks
Moderate to Vigorous Physical Activity (MVPA) was assessed using five days (4 weekdays and 1 weekend day) of actigraphy (ActiGraph).
Change in Steps Per Day From Baseline at 12 Weeks.
时间窗: Baseline and at 12 weeks
Steps per day was assessed using five days (4 weekdays and 1 weekend day) of actigraphy (ActiGraph).
