The present study investigated emotional and somatic consequences of the daily eating episodes of 19 bulimics, 15 bingers, and 20 normal control subjects. For 1 week, subjects rated 21 emotional and somatic states immediately following all eating episodes and 1 h later. Results indicated that bulimics and bingers reported significantly greater negative and somatic consequences immediately following their binge episodes than normal eaters following all of their eating episodes. For both groups, these negative emotional consequences persisted over time. Following nonbinge episodes, only bulimics reported experiencing significantly greater negative emotions than normal controls. Comparisons of the binge and nonbinge episodes of the bulimics and bingers indicated that binge episodes are followed by greater immediate and delayed negative and somatic consequences than nonbinge episodes. Furthermore, the positive emotions that occur immediately after a binge significantly decrease in intensity within 90 min after the episode. Theoretical and clinical implications of these findings are discussed.
本研究调查了19名神经性贪食症患者、15名暴饮暴食者和20名正常对照者日常进食发作的情绪和身体影响。在为期1周的时间里，受试者在每次进食发作后立即以及1小时后对21种情绪和身体状态进行评分。结果表明，神经性贪食症患者和暴饮暴食者在暴饮暴食发作后立即报告的负面和身体影响明显大于正常进食者在所有进食发作后的影响。对两组而言，这些负面情绪影响会随着时间持续存在。在非暴饮暴食发作后，只有神经性贪食症患者报告的负面情绪明显多于正常对照组。对神经性贪食症患者和暴饮暴食者的暴饮暴食发作与非暴饮暴食发作进行比较表明，暴饮暴食发作后立即和延迟出现的负面和身体影响比非暴饮暴食发作更大。此外，暴饮暴食后立即出现的积极情绪在发作后90分钟内强度会显著降低。本文讨论了这些发现的理论和临床意义。
