焦虑敏感度升高的人(AS；即对躯体唤醒的恐惧)可能会暴饮暴食以减轻情绪困扰。由于体育活动减少了应激反应，我们预测：(1)体育活动会缓和AS与暴食之间的关系；(2)饮食应对动机会中介AS与暴食之间的联系，因此对于那些体育活动较少的人来说，这种关系会更强。参与者(N=167)完成了在线自我报告测量。回归分析显示，中等强度体力活动(MPA)缓和了AS与暴饮暴食的关系，因此，在经常参加MPA的人中，AS与暴饮暴食无关，而在那些没有报告参与MPA的人中，AS与暴饮暴食有关。剧烈的体力活动(VPA)则朝着相反的方向减缓，因此在VPA水平高的人中，AS与暴饮暴食之间的关系是显著的，而在VPA水平低的人中，这一关系就不那么强烈了。中介模型也是显著的，但不受MPA或VPA的调节。文中还讨论了理论和临床意义。(C)2012爱思唯尔有限公司。保留所有权利。
Individuals with elevated anxiety sensitivity (AS; i.e., fear of somatic arousal) may binge eat to reduce emotional distress. Because physical activity reduces stress reactivity, we predicted that: (1) the relation between AS and binge eating would be moderated by physical activity and (2) coping motives for eating would mediate the association between AS and binge eating such that the relation would be stronger for those low in physical activity. Participants (N=167) completed online self-report measures. Regression analyses revealed that moderate-intensity physical activity (MPA) moderated the relation between AS and binge eating such that AS was not related to binge eating among those who frequently engaged in MPA but was related to binge eating among those who did not report engaging in MPA. Vigorous-intensity physical activity (VPA) moderated in the opposite direction such that the relation between AS and binge eating was significant among persons reporting high levels of VPA but less strong among persons reporting low levels of VPA. The mediation model was also significant, but was not moderated by MPA or VPA. Theoretical and clinical implications are discussed. (C) 2012 Elsevier Ltd. All rights reserved.
