许多神经性贪食症（BN）患者也符合终身酒精使用障碍（AUD）的标准。为了了解导致这些疾病共同发生和持续存在的可能机制，本研究通过比较仅BN（n = 18），BN和当前/过去AUD（n = 13）以及健康对照（n = 12）的女性，研究了BN患者冲动性和试验餐摄入的重要性。所有参与者都通过问卷调查和两次半结构化访谈完成了对进食障碍症状，饮酒频率，暴饮暴食和清除的评估。冲动的措施包括计算机和自我报告的措施，实验室测试餐。BN伴/不伴共病AUD的个体之间在试验餐摄入量、冲动性测量或自我报告的心理症状方面没有发现显著差异。正如假设的那样，与健康对照组相比，BN患者在两个分量表和Barratt冲动量表（冲动的一种特质测量）的总分上的得分显着更高，并且在暴饮暴食指导餐中消耗了显着更多的卡路里。总Barratt冲动量表评分也显着相关的千卡消耗在实验室测试餐时，个人被指示暴饮暴食（BN组）。这项研究的数据增加了现有的文献，暗示冲动性暴食症的精神病理学，包括BN，也支持使用实验室餐作为一个特定的衡量这一特点的饮食失调人群。
Many patients with bulimia nervosa (BN) also meet criteria for a lifetime alcohol use disorder (AUD). In order to understand possible mechanisms contributing to the co-occurrence and perpetuation of these disorders, this study investigated the importance of impulsivity and test meal intake among patients with BN by comparing women with BN only (n = 18), BN and current/past AUDs (n = 13), and healthy controls (n = 12). All participants completed assessments of eating disorder symptoms, frequency of alcohol use, binge eating, and purging via questionnaires and semi-structured interviews over two sessions. Measures of impulsivity consisted of computerized and self-report measures, and laboratory test meals. Significant differences between individuals with BN with/without comorbid AUDs were not found for test meal intake, impulsivity measures, or self-reported psychological symptoms. As hypothesized, compared to healthy controls, individuals with BN had significantly higher scores on two subscales and the total score of the Barratt Impulsiveness Scale, a trait measure of impulsivity, and consumed significantly more calories in the binge instruction meal. Total Barratt Impulsiveness Scale scores were also significantly related to kcal consumed during the laboratory test meal when individuals were instructed to binge eat (BN groups). Data from this study add to the existing literature implicating impulsivity in the psychopathology of disorders of binge eating, including BN, and also support the use of laboratory meals as a symptom-specific measure of this trait in eating disorder populations.
