To examine the relationships among nonpurge binge eating, emotional eating, and diet-related self-efficacy in perimenopausal women, a population at risk for weight gain.
Descriptive correlational study.
Secondary analysis of baseline data for a weight gain prevention intervention, Mindful Restaurant Eating, with a sample of healthy perimenopausal women (n = 43).
Controlling for age and body mass index, the binge eating severity was associated with emotional eating (partial r = .71; p ≤ .01) and was negatively associated with diet-related self-efficacy (partial r = -.49; p ≤ .05). There was a significant difference (p < .01) in emotional eating scores between women with moderate to high binge eating severity scores and those with low binge eating severity scores. Participants with higher binge eating severity also had less diet-related self-efficacy, especially with regard to resisting relapse and reducing calorie intake.
Perhaps perceived loss of control, a central component to binge eating, negatively affects one's ability to consistently attain dietary goals, thus affecting self-efficacy. Interventions increasing diet-related self-efficacy may prove useful in decreasing the amount of excess calories consumed because of emotional eating and/or binge eating behavior.
研究围绝经期女性（一个有体重增加风险的人群）中，非清除型暴饮暴食、情绪化进食与饮食相关自我效能之间的关系。
描述性相关性研究。
对一项预防体重增加干预措施“正念餐厅饮食”的基线数据进行二次分析，样本为健康的围绝经期女性（n = 43）。
在控制年龄和体重指数后，暴饮暴食严重程度与情绪化进食相关（偏相关系数r = 0.71；p≤0.01），与饮食相关自我效能呈负相关（偏相关系数r = -0.49；p≤0.05）。暴饮暴食严重程度评分中等至高的女性与评分低的女性在情绪化进食得分上存在显著差异（p < 0.01）。暴饮暴食严重程度较高的参与者饮食相关自我效能也较低，尤其是在抵抗复发和减少卡路里摄入方面。
或许，暴饮暴食的核心要素——失控感，会对一个人持续实现饮食目标的能力产生负面影响，进而影响自我效能。提高饮食相关自我效能的干预措施可能有助于减少因情绪化进食和/或暴饮暴食行为而摄入的多余热量。
