简要总结
The goal of this pilot study is to examine how to design a large-scale randomized control trial examining yoga as a way to improve positive body image in men and women across the lifespan. The main questions it will answer are:
- Is the study acceptable to participants?
- Is recruitment, adherence, and retention adequate?
- Are study procedures appropriate?
- What is the preliminary effect of yoga on embodiment (sense of connection with the body), self-objectification (evaluating oneself based on outer appearance rather than internal functions) and body appreciation?
Participants will either take part in a 10-week yoga program or a control condition (where they will be asked to not change their lifestyle). They will complete online questionnaires at the start, middle and end of the 10-weeks.
详细描述
The purposes of this pilot study are:
- To evaluate the feasibility and acceptability of a randomized control trial by assessing participant retention, data collection procedures, and adherence to engaging in a supervised Hatha yoga intervention (or control group).
- To examine preliminary effects of a yoga intervention on embodiment, self-objectification, and positive body image (i.e., body appreciation) among a diverse sample of adults men and women.
Specifically, we will test whether a 10-week Hatha yoga program will contribute to improvements in body appreciation via a) greater embodiment, and b) lower self-objectification This will allow us to calculate effect sizes for sample size calculations for future randomized controlled trials.
Clearance from the university Research Ethics Board will be obtained prior to study commencement. Participants will be recruited from community centres, social media, and traditional media in the Niagara Region. Potential participants will contact the researcher if they are interested in participating. Eligible and interested participants will be provided with a link to the baseline survey via Qualtrics, where they will complete informed consent, demographic information and measures of physical activity and body image. Once questionnaires have been completed, participants will be randomly assigned (using Microsoft Excel to randomize) to either the yoga or control group. They will be provided with instructions for their group at this time via email. They will then undergo either the 10-week yoga intervention or the control condition (see below for descriptions).
Participants will be asked to complete the same physical activity and body image measures during week 5 and at the end of 10 weeks via Qualtrics. At the final time point, participants will also be asked to complete feasibility measures (e.g., acceptability, appropriateness and feasibility of the intervention and control groups), as well as a series of questions asking about their perceptions of the yoga intervention or control group. Upon completion of all measures, participants will be fully debriefed as to the true purpose of the study and the use of deception (i.e., true purpose of the study related to positive body image); they will then be asked to provide continuing informed consent. In addition, the yoga instructors will also be asked a series of questions regarding their perceptions of the yoga intervention.

结局指标
主要结局
Body appreciation
时间窗: 10 weeks
Body Appreciation Scale-2 (Tylka \& Wood-Barcalow, 2015); 10 items, with each one rated on a 5-point scale ranging from 1 = never to 5 = always. Scores on the BAS-2 are averaged where higher scores represent higher levels of body appreciation.
次要结局
- Authentic body pride(10 weeks)
- Fitness-related authentic body pride(10 weeks)
- Satisfaction with function of the body and appearance of the body as assessed by Satisfaction with Body Function and Body Appearance Scale (Reboussin et al., 2000);(10 weeks)
- Drop-out(10 weeks)
- Feasibility of intervention as assessed by Weiner et al.'s (2017) feasibility measure(10 weeks)
