This study tested whether distress tolerance, body image, and body mass index (BMI) predicted adherence to a yoga intervention. Participants were 27 women who participated in a yoga intervention as part of a randomized controlled trial. Attendance and distress tolerance were assessed weekly, and body image and BMI were measured at baseline. Multilevel modeling revealed a three-way interaction of distress tolerance, BMI, and body image (p < .001). For participants with few body image concerns, distress tolerance was positively associated with adherence regardless of BMI (p = .009). However, for those with poor body image, increases in distress tolerance were associated with increases in adherence among overweight participants (p < .001) but lower adherence among obese participants (p = .007). Distress tolerance may be implicated in adherence to a yoga intervention, although its effects may be dependent on body image concerns, BMI, and their interaction. Research and clinical implications are discussed.
本研究测试了痛苦耐受力、身体意象和体重指数（BMI）是否能预测对瑜伽干预的依从性。参与者为27名女性，她们作为随机对照试验的一部分参与了瑜伽干预。每周评估出勤情况和痛苦耐受力，并在基线时测量身体意象和BMI。多水平模型显示痛苦耐受力、BMI和身体意象之间存在三向交互作用（p < .001）。对于身体意象问题较少的参与者，无论BMI如何，痛苦耐受力与依从性呈正相关（p = .009）。然而，对于身体意象较差的参与者，痛苦耐受力的增加与超重参与者的依从性增加相关（p < .001），但与肥胖参与者的依从性降低相关（p = .007）。痛苦耐受力可能与对瑜伽干预的依从性有关，尽管其影响可能取决于身体意象问题、BMI及其交互作用。文中讨论了研究和临床意义。
