未经批准:暴食症(BED)作为一种公共卫生问题已被纳入《精神疾病诊断和统计手册》,第五版(DSM-5)。类似于成瘾性障碍,与冲动性相关的神经心理学结构可能参与BED的发生和发展。然而,目前尚不清楚冲动的哪些方面与非临床人群的暴饮暴食和暴饮暴食行为有关.本研究旨在检测未确诊的年轻人的人格特质和行为选择水平上的冲动性和暴饮暴食之间的关系。
未经证实:58名可能患有BED的个体和59名健康对照者,年龄相匹配,性别,和教育水平,通过一系列自我报告测量来评估,包括Barratt冲动量表(BIS-11),UPPS-P冲动行为量表(UPPS-P),延迟贴现测试(DDT),和概率贴现测试(PDT)。
UASSIGNED:多变量方差分析模型显示,与健康对照相比,可能的BED组在BIS-11注意和运动冲动方面得分升高,关于UPPS-P负紧迫性,积极的紧迫性,缺乏毅力。然而,可能的BED受试者在DDT和PDT上的折现率与健康对照组相似。回归模型发现,负紧迫性是暴饮暴食行为的唯一积极预测因素。
未经评估:这些研究结果表明,特质冲动的典型方面,在成瘾性疾病中已经被认识到,与年轻人的暴饮暴食有关,而在同一可能的BED样本中并未发现异常的选择冲动。这项研究可能会促进对BED发病机制的更好理解。
UNASSIGNED: Binge eating disorder (BED) as a public health problem has been included in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Akin to addictive disorders, impulsivity-related neuropsychological constructs might be potentially involved in the onset and development of BED. However, it remains unclear which facets of impulsivity are connected to overeating and binge eating behaviors among non-clinical populations. The present study aimed to detect the relationship between impulsivity and binge eating both on the personality-trait and behavioral-choice levels in undiagnosed young adults.
UNASSIGNED: Fifty-eight individuals with probable BED and 59 healthy controls, matched on age, gender, and educational level, were assessed by using a series of self-report measurements, including the Barratt Impulsiveness Scale (BIS-11), UPPS-P Impulsive Behaviors Scale (UPPS-P), Delay Discounting Test (DDT), and Probability Discounting Test (PDT).
UNASSIGNED: Multivariate analysis of variance models revealed that compared with healthy controls, the probable BED group showed elevated scores on the BIS-11 Attentional and Motor impulsiveness, and on the UPPS-P Negative Urgency, Positive Urgency, and Lack of Perseverance. However, the probable BED subjects had similar discounting rates on the DDT and PDT with healthy controls. Regression models found that Negative Urgency was the only positive predictor of binge eating behavior.
UNASSIGNED: These findings suggested that typical facets of trait impulsivity, which have been recognized in addictive disorders, were associated with binge eating in young adults, whereas choice impulsivity was not aberrantly seen in the same probable BED sample. This study might promote a better understanding of the pathogenesis of BED.
