Abstract：
OBJECTIVE: Individuals with bulimia nervosa (BN) engage in both maladaptive (i.e., compulsive and/or compensatory) and adaptive exercise (e.g., for enjoyment). No research has examined whether those who engage in adaptive, compulsive, and/or compensatory exercise exhibit differences in BN pathology or treatment outcome compared to those not engaging in exercise, limiting intervention efficacy.
METHODS: We examined associations of baseline exercise engagement with baseline and posttreatment BN pathology among 106 treatment-seeking adults (Mage = 37.4, SDage = 12.95, 87.74% female, 68.87% White) enrolled across four clinical trials of outpatient enhanced cognitive behavioral therapy for BN (range: 12-16 sessions). Analysis of covariances examined associations between baseline exercise type and baseline/posttreatment global eating pathology, dietary restraint, loss-of-control (LOC) eating, and purging frequency.
RESULTS: Those engaging in only adaptive exercise reported lower global eating pathology compared to those engaging in compulsive-only exercise (Est = -1.493, p = .014, Mdiff = -.97) while those engaging in baseline compulsive exercise reported less LOC eating compared to those not engaging in exercise (Est = -22.42, p = .012, Mdiff = -12.50). Baseline engagement in compulsive-only exercise was associated with lower posttreatment global eating pathology compared to baseline engagement in no exercise (Est = -.856, p = .023, Mdiff = -.64) and both compulsive and compensatory exercise (Est = .895, p = .026, Mdiff = -1.08).
CONCLUSIONS: Those engaging in compulsive, compensatory, adaptive, and no exercise exhibit different patterns and severity of BN pathology. Future research is needed to position treatments to intervene on maladaptive, while still promoting adaptive, exercise.
UNASSIGNED: No research to date has examined whether those who engage in adaptive, compulsive, and/or compensatory exercise exhibit differences in BN pathology or treatment outcome compared to those not engaging in exercise, limiting targeted intervention efforts. We found that those engaging in compulsive, compensatory, and adaptive exercise exhibit different patterns of BN pathology and that adaptive exercise engagement was related to lower cognitive eating disorder symptoms at baseline.

摘要：
目的：患有神经性贪食症（BN）的个体都有适应不良的情况（即强迫性和/或补偿性)和适应性锻炼(例如，为了享受)。没有研究检查那些从事适应性的人是否，强迫性,和/或代偿性运动与不参与运动的患者相比，在BN病理或治疗结果方面存在差异，限制干预效果。
方法：我们检查了106名寻求治疗的成年人的基线运动参与与基线和治疗后BN病理的关联（Mage=37.4，SDage=12.95，87.74％为女性，68.87％的白人）参加了BN门诊增强认知行为疗法的四项临床试验（范围：12-16次）。协方差分析检查了基线运动类型与基线/治疗后整体饮食病理学之间的关联，饮食限制，失控(LOC)饮食，和吹扫频率。
结果：与仅进行强迫性运动的人相比，仅进行适应性运动的人报告的总体饮食病理较低（Est=-1.493，p=.014，Mdiff=-.97），而与不进行运动的人相比，进行基线强迫性运动的人报告的LOC饮食较少（Est=-22.42，p=.012，Mdiff与不进行运动的基线参与相比，仅进行强迫性运动的基线参与与较低的治疗后总体饮食病理相关（Est=-.856，p=.023，Mdiff=-.64）以及强迫性和补偿性运动（Est=.895，p=.026，Mdiff=-1.08）。
结论：那些从事强迫性，补偿性,适应性，没有运动表现出不同的BN病理模式和严重程度。未来的研究需要定位治疗以干预适应不良，在促进适应性的同时，锻炼。
■到目前为止，还没有研究检查那些从事适应性的人强迫性,和/或代偿性运动与不参与运动的患者相比，在BN病理或治疗结果方面存在差异，限制有针对性的干预努力。我们发现那些强迫性的人，补偿性,和适应性运动表现出不同的BN病理模式，并且适应性运动参与与基线时认知进食障碍症状降低有关。
