本研究的目的是确定分散注意力和集中注意力对非临床饮食失调水平的女性的食物摄入量和感知摄入量的准确性的影响。在一项实验室研究中，27名年轻女性连续三周每周吃一次相同的面食。在对照和两个测试条件下，随意进食，其中注意力被转移（分心条件）或针对食物相关的刺激（集中注意力条件）。他们还完成了饮食失调量表-2中的瘦、暴食和身体不满意分量表。摄入量显着高于分心比在控制或集中注意力的条件下，但不相关的饮食精神病理学。一项测量摄入量的准确性的研究表明，在集中注意力的条件下，对瘦的追求与高估食物摄入量有关。这项研究表明，分散注意力可以促进所有非临床消费者的食物摄入量，无论饮食行为的个体差异如何。此外，它表明，那些对瘦有高度追求的人在需要专注于食物时可能会高估摄入量。这些发现可能对饮食失调治疗中的进餐时间干预有影响。(C)2010爱思唯尔有限公司版权所有。
The aim of this study was to determine the effects of distraction and focused attention on both food intake and accuracy of perceived intake in women with non-clinical levels of disordered eating. In a laboratory study, twenty-seven young women consumed three identical pasta meals once a week for three consecutive weeks. Meals were eaten ad libitum during a control and two test conditions, in which attention was either diverted away from (distraction condition) or directed towards food-related stimuli (focused attention condition). They also completed the drive for thinness, bulimia and body dissatisfaction subscales of the Eating Disorders Inventory-2. Intake was significantly higher in the distraction than in the control or focused attention conditions, but was not related to eating psychopathology. A measure of accuracy of perceived intake indicated that drive for thinness was associated with overestimation of food intake in the focused attention condition. This study suggests that distraction could promote food intake in all non-clinical consumers, irrespective of individual differences in eating behaviours. Furthermore, it suggests that those with a high drive for thinness may overestimate intake when required to focus on their food. These findings could have implications for mealtime interventions in the treatment of eating disorders. (C) 2010 Elsevier Ltd. All rights reserved.
