Trauma exposure and obesity are highly prevalent among college students and both are associated with disordered eating. There is a need to understand psychological factors that may be related to maladaptive eating behavior among college students with obesity and a history of trauma exposure.
Participants included 139 college students with obesity (defined as a BMI ≥ 30) and a history of trauma exposure (76.3% females; = 25.4 years, = 8.07). The current study conducted three separate two-step hierarchical regressions examining mindful attention, and its relation to eating expectancies (expectancies of eating to help manage negative affect, expectancies of eating to alleviate boredom, and expectancies of eating to lead to feeling out of control).
Results indicated that lower levels of mindful attention were related to greater levels of expectancies of eating to help manage negative affect ( = -4.16, = 1.08, = .023, = -7.72, -0.60, = .04), expectancies of eating to alleviate boredom ( = -1.09, = 0.39, = .006, = -1.86, -0.32, = .06), and expectancies of eating to lead to feeling out of control ( = -1.62, = 0.40, < .001, = -2.41, -0.83, = .11). Results were observed over, and above variance accounted for by sex (assigned at birth), body mass index (BMI), and posttraumatic stress disorder (PTSD) symptom severity.
Overall, the results from the present investigation suggest the potential importance and need for future research in the role of mindful attention in relation to several distinct eating expectancies associated with maladaptive eating.
创伤暴露和肥胖在大学生中非常普遍，且两者都与饮食失调有关。有必要了解可能与有肥胖和创伤暴露史的大学生适应不良饮食行为相关的心理因素。
参与者包括139名有肥胖（定义为体重指数≥30）和创伤暴露史的大学生（76.3%为女性；平均年龄 = 25.4岁，标准差 = 8.07）。本研究进行了三次独立的两步分层回归，检验正念注意力及其与饮食期望（通过进食来帮助管理负面影响的期望、通过进食来缓解无聊感的期望以及进食会导致失控感的期望）的关系。
结果表明，较低水平的正念注意力与通过进食来帮助管理负面影响的更高期望水平（β = -4.16，标准误 = 1.08，p = .023，95%置信区间 = -7.72，-0.60）、通过进食来缓解无聊感的期望（β = -1.09，标准误 = 0.39，p = .006，95%置信区间 = -1.86，-0.32）以及进食会导致失控感的期望（β = -1.62，标准误 = 0.40，p < .001，95%置信区间 = -2.41，-0.83）相关。这些结果在排除了出生时指定的性别、体重指数（BMI）和创伤后应激障碍（PTSD）症状严重程度所解释的方差之后仍然存在。
总体而言，本调查结果表明了正念注意力在与适应不良饮食相关的几种不同饮食期望方面的潜在重要性以及未来研究的必要性。
