Abstract

The purpose of this study was to evaluate the Night Eating Questionnaire (NEQ) as a measure of severity of the Night Eating Syndrome (NES). The 14-item NEQ assesses the behavioral and psychological symptoms of NES. The NEQ was evaluated in three samples: 1980 persons who completed the NEQ on the Internet; 81 persons diagnosed with NES; and 194 bariatric surgery candidates. Study 1, using principal components analysis, generated four factors (nocturnal ingestions, evening hyperphagia, morning anorexia, and mood/sleep) and an acceptable alpha (.70). Confirmatory factor analysis suggested that 99% of covariation among factors is accounted for by a higher-order construct. Study 2 found convergent validity of the NEQ with additional measures of night eating, disordered eating, sleep, mood, and stress. Study 3 compared scores from obese bariatric surgery candidates with and without NES and found appropriate discriminant validity of the NEQ. The NEQ appears to be an efficient, valid measure of severity for NES.

摘要

本研究的目的是评估夜食问卷(NEQ)作为夜食综合征(NES)严重程度的一种测量工具。这份包含14个条目的NEQ评估了NES的行为和心理症状。NEQ在三个样本中进行了评估:1980名在互联网上完成NEQ的人;81名被诊断为NES的人;以及194名减肥手术候选人。研究1采用主成分分析,得出了四个因子(夜间进食、晚间多食、早晨厌食以及情绪/睡眠)和一个可接受的阿尔法系数(0.70)。验证性因子分析表明,各因子之间99%的协方差可由一个高阶结构来解释。研究2发现NEQ与夜食、饮食失调、睡眠、情绪和压力的其他测量方法具有收敛效度。研究3比较了有和没有NES的肥胖减肥手术候选人的得分,发现NEQ具有适当的判别效度。NEQ似乎是一种有效测量NES严重程度的工具。
