简要总结
The purpose of this study is to test the efficacy of an 8-week, remotely-delivered, flow-based and moderate-intensity yoga intervention (vs. waitlist control), on stress and cognitive functioning. Participants will include individuals who are full-time working adults between the ages of 18 and 64, and currently experiencing symptoms of psychosocial stress or anxiety.
详细描述
Participants who pass a telephone screening, electronically sign our informed consent agreement, and complete baseline testing, will be randomized to one of two groups: yoga intervention or a waitlist control group. Before and after the 8-week intervention, participants will complete psychosocial questionnaires and computerized cognitive testing. The remote intervention will be delivered via Google Meet and will be led by a certified yoga instructor. During the course of the intervention, participants will be wearing a consumer grade accelerometer to track heart rate during yoga sessions and physical activity during the 8 weeks.

研究组 & 干预措施
Moderate-intensity flow-based Yoga
The intervention will consist of participants engaging in a progressive series of moderate-intensity, flow-based yoga poses, along with breathing and relaxation, for eight weeks. The intervention will be titrated in terms of supervision, with first two weeks being completely supervised, followed by partial supervision for three weeks, and three weeks of unsupervised sessions. The sessions will be ~50 minutes long, 3 times/week. All supervised sessions will be conducted online through Google Meet (GM), which is a live video interaction platform. Videos will be provided to guide unsupervised sessions. Sessions will be led by a certified yoga instructor. An orientation will be provided in the first week, given that the participants will have no or minimal experience with yoga. The intervention will consist of basic sun salutations of hatha yoga sun salutation A, sun salutation B and flow sequences, and breathing exercises, and relaxation.
干预措施: Yoga (Behavioral)
Waitlist control
Participants in this group will not receive the 8-week intervention during the course of the study, and will be asked to engage in their regular activities. They will be asked to not start any new activities during the study period. After they complete the study, they will be provided with the same intervention (live instruction, feedback and supportive videos).
结局指标
主要结局
Perceived Stress
时间窗: Change from baseline at 8 weeks
The Perceived Stress Scale (PSS), developed by Cohen, Kamarck, and Mermelstein (1983) will be used to measure perceived psychosocial stress. The PSS is a 10-item scale that measures the extent to which situations are perceived as stressful. Responses range from 0 (Never) to 4 (Very often) and higher scores indicate a higher level of perceived stress. The Brief Job Stress Questionnaire, developed by Kawada and Otsuka (2011), is a 15-item scale measuring job stress. It focuses on the evaluation of job demands, job control, job support, and degree of job satisfaction. Responses range from 1 (Agree) to 4 (Disagree) and higher scores indicate a lower level of stress.
次要结局
- Task switching paradigm(Change from baseline at 8 weeks)
- Stroop task(Change from baseline at 8 weeks)
- Digit span forward and backward(Change from baseline at 8 weeks)
- Digit symbol substitution test (DSST)(Change from baseline at 8 weeks)
