The Night Eating Diagnostic Questionnaire (NEDQ) is a validated assessment of the night eating syndrome (NES) based on the proposed diagnostic criteria. While past results show that NEDQ is associated with psychopathology and body mass index (BMI), the relationships between the proposed NES diagnostic criteria and psychopathology and BMI have not been investigated. Thus, the relationships between the proposed NES diagnostic criteria and factors previously associated with NES, namely depression, "food addiction" (FA), sleep quality, and BMI were examined. Finally, the NEDQ factor structure was examined for the first time in order to determine whether the NEDQ is assessing NES appropriately.
The NEDQ, depression, sleep quality, and FA questionnaires were administered to a sample of older community members ( = 468) and a student sample ( = 254). Principal Components Analysis (PCA) was performed to examine the factor structure of the NEDQ. The relationships between the proposed diagnostic criteria and depression, sleep quality, FA, and BMI were examined using multiple regression.
The proposed NES criteria were highly intercorrelated. PCA revealed a single factor solution for the NEDQ. In the community sample, depression was associated with the presence of five of nine proposed diagnostic criteria while poor sleep quality and FA were associated with the presence of seven and six criteria respectively. In the community sample, only the sleep problems and impairment/distress criteria were positively associated with BMI. In the student sample, fewer criteria were associated with psychopathology, and no criteria were associated with BMI.
These findings support the proposed criteria for diagnosis of NES. All proposed criteria were associated with at least one psychopathology measure. BMI was only associated with the sleep problems and impairment/distress criteria in the community sample. The PCA finding of a single factor indicates that the NEDQ is a cohesive assessment of NES, and that the NEDQ is a good measure of NES criteria.
夜间进食诊断问卷（NEDQ）是基于拟议的诊断标准对夜间进食综合征（NES）进行的有效评估。虽然过去的结果表明NEDQ与精神病理学和体重指数（BMI）相关，但尚未对拟议的NES诊断标准与精神病理学和BMI之间的关系进行研究。因此，研究了拟议的NES诊断标准与先前与NES相关的因素之间的关系，即抑郁、“食物成瘾”（FA）、睡眠质量和BMI。最后，首次对NEDQ的因子结构进行了研究，以确定NEDQ是否对NES进行了适当评估。
对老年社区成员样本（n = 468）和学生样本（n = 254）进行了NEDQ、抑郁、睡眠质量和FA问卷调查。进行主成分分析（PCA）以检验NEDQ的因子结构。使用多元回归分析了拟议的诊断标准与抑郁、睡眠质量、FA和BMI之间的关系。
拟议的NES标准之间高度相关。PCA显示NEDQ的单因素解决方案。在社区样本中，抑郁与九个拟议诊断标准中的五个存在相关，而睡眠质量差和FA分别与七个和六个标准存在相关。在社区样本中，只有睡眠问题和损害/痛苦标准与BMI呈正相关。在学生样本中，与精神病理学相关的标准较少，且没有标准与BMI相关。
这些发现支持了拟议的NES诊断标准。所有拟议标准均与至少一项精神病理学测量相关。BMI仅与社区样本中的睡眠问题和损害/痛苦标准相关。PCA的单因素发现表明NEDQ是对NES的连贯评估，并且NEDQ是NES标准的良好测量指标。
