虽然40-60%的进食障碍（ED）患者报告参与适应不良的运动，但自我报告的运动原因各不相同。此外，没有研究检查运动的瞬间原因，以及运动的原因是否对任何事件都是适应性的和不适应的。检查运动的原因可以为更有效地针对适应不良运动的干预提供信息。目前的研究招募了患有暴食频谱ED的成年人（N=58，89.2%女性），并使用生态瞬时评估评估了7-14天内自我报告的运动原因。如果参与者赞同通过锻炼来补偿进食或感觉被驱使去锻炼，则锻炼事件被归类为适应不良。平均而言，参与者报告在7-14天内锻炼8次（SD=8）。平均而言，73%的运动事件是适应不良的。参与者最常表示锻炼是为了控制形状或体重（67.2%的事件），感觉有动力（62.9%），以及锻炼是日常生活的一部分（52.9%）。参与者最不赞成锻炼，以便他们可以吃得更多（9.8%）。参与者在每次发作时报告了平均3.6个运动原因（SD=1.85，众数=1.0）。正如假设的那样，ED患者在每次锻炼时都有几个原因。此外，在何种程度上，每一个锻炼插曲是适应不良的参与者之间的变化，甚至在一个单一的参与者的锻炼插曲。这些发现强调了研究评估何时以及对谁来说，运动变得适应不良的重要性，以及研究ED适应不良和适应性运动的其他特征的重要性。
Although 40–60% of individuals with eating disorders (EDs) report engaging in maladaptive exercise, self-reported reasons for engaging in exercise vary. Further, no studies have examined momentary reasons for exercise and whether reasons for exercising could be both adaptive and maladaptive for any episode. Examining reasons for exercise can inform interventions which more effectively target maladaptive exercise. The current study recruited adults with binge-spectrum EDs (N=58, 89.2% Female) and assessed self-reported reasons for exercise using ecological momentary assessment over 7–14 days. Exercise episodes were categorized as maladaptive if the participant endorsed exercising to compensate for eating or feeling driven to exercise. On average, participants reported exercising 8 times (SD=8) over the 7–14 days. On average, 73% of exercise episodes were maladaptive. Participants most frequently stated exercising to control shape or weight (67.2% of episodes), feeling driven (62.9%), and exercising as part of a routine (52.9%). Participants least endorsed exercising so that they could eat more later (9.8%). Participants reported a mean of 3.6 reasons for exercising at each episode (SD=1.85, mode=1.0). As hypothesized, individuals with EDs were exercising for several reasons at each exercise episode. Further, the extent to which each exercise episode is maladaptive varied between participants and even within a single participant’s exercise episodes. These findings underscore the importance of research evaluating when, and for whom, exercise becomes maladaptive, as well as research examining other characteristic features of maladaptive and adaptive exercise in EDs.
