Eating in response to negative emotions is associated with binge or loss of control (LOC) eating in adults. Although children report engaging in LOC eating, data on emotional eating among youth are limited.
We adapted the adult Emotional Eating Scale (Arnow et al., Int J Eat Disord, 18, 79-90, 1995) to be used with children and adolescents (EES-C). Fifty-nine overweight (BMI > or = 95th percentile for age and sex) and 100 non-overweight (BMI 5th-94th percentile) participants (mean age +/- SD 14.3 +/- 2.4 years) completed the EES-C, and measures of recent LOC eating and general psychopathology. Test-retest reliability was assessed in 64 children over a 3.4 +/- 2.6 month interval.
A factor analysis generated three subscales: eating in response to anxiety, anger, and frustration (EES-C-AAF), depressive symptoms (EES-C-DEP), and feeling unsettled (EES-C-UNS). Internal consistency for the subscales was established; Cronbach's alphas for the EES-C-AAF, EES-C-DEP, and EES-C-UNS were 0.95, 0.92, and 0.83, respectively. The EES-C had good convergent validity: children reporting recent LOC eating episodes scored higher on all subscales (p's < 0.05). The EES-C-AAF and EES-C-UNS subscales demonstrated good discriminant validity and the EES-C-DEP revealed adequate discriminant validity. Intra-class correlation coefficients revealed good temporal stability for each subscale (EES-C-AAF = 0.59, EES-C-DEP = 0.74, EES-C-UNS = 0.66; p's < 0.001).
The EES-C has good convergent and discriminant validity, and test-retest reliability for assessing emotional eating in children. Further investigation is required to clarify the role emotional eating may play in children's energy intake and body weight.
因负面情绪而进食与成年人的暴饮暴食或失控性进食有关。尽管儿童报告有失控性进食行为,但关于青少年情绪性进食的数据有限。
我们对成人情绪性进食量表(阿诺等人,《国际进食障碍杂志》,第18卷,第79 - 90页,1995年)进行了改编,使其适用于儿童和青少年(EES - C)。59名超重(BMI大于或等于年龄和性别的第95百分位数)和100名非超重(BMI处于第5 - 94百分位数)的参与者(平均年龄±标准差14.3±2.4岁)完成了EES - C量表,以及近期失控性进食和一般精神病理学的测量。在64名儿童中,间隔3.4±2.6个月评估了重测信度。
因素分析产生了三个子量表:因焦虑、愤怒和沮丧而进食(EES - C - AAF)、抑郁症状(EES - C - DEP)以及感觉不安(EES - C - UNS)。确立了各子量表的内部一致性;EES - C - AAF、EES - C - DEP和EES - C - UNS的克朗巴哈α系数分别为0.95、0.92和0.83。EES - C具有良好的收敛效度:报告近期有失控性进食发作的儿童在所有子量表上得分更高(p值<0.05)。EES - C - AAF和EES - C - UNS子量表显示出良好的区分效度,EES - C - DEP显示出足够的区分效度。组内相关系数显示每个子量表都有良好的时间稳定性(EES - C - AAF = 0.59,EES - C - DEP = 0.74,EES - C - UNS = 0.66;p值<0.001)。
EES - C在评估儿童情绪性进食方面具有良好的收敛效度和区分效度以及重测信度。需要进一步研究以阐明情绪性进食在儿童能量摄入和体重方面可能发挥的作用。
