title: Distress Tolerance as a Predictor of Adherence to a Yoga Intervention: Moderating Roles of BMI and Body Image.
abstract: 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.
