Night eating syndrome (NES) severity is usually assessed with the Night Eating Questionnaire (NEQ). Although the most common version of the NEQ is composed of 14 items (NEQ-14), two additional items measuring distress associated with the night eating have been proposed, but they have never been included in past psychometric studies. The aim of the present study was to create an Italian version of the NEQ-16 (I-NEQ-16), with the inclusion of the proposed items for assessing the distress associated with night eating. A major objective of the study was to propose a unidimensional version of the I-NEQ-16 and investigate its psychometric properties. 482 Italian adults (380 women and 102 men; mean age = 25.5, = 10.9 years old) were administered the Italian versions of the NEQ, the Night Eating Diagnostic Questionnaire (NEDQ), and questionnaires measuring binge eating, emotional and external eating, diurnal chronotype, insomnia, and anxiety and depression severity. In order to improve the unidimensionality of the I-NEQ-16, we removed from further analyses items 1, 4, and 7, because they increased the heterogeneity of the measure. Confirmatory factor analysis, indicated the fit of a modified one-factor model, allowing correlated errors between three pairs of items. I-NEQ-16 scores were significantly associated with all concurrent questionnaire scores and were able to categorize individuals according to their diagnosis of NES according to the NEDQ. Thus, the I-NEQ-16 is a valid measure that is potentially useful for investigating correlates of night eating in the general population.
夜食症(NES)的严重程度通常采用夜食问卷(NEQ)进行评估。尽管NEQ最常见的版本由14个项目组成(NEQ - 14),但另外两个测量与夜食相关困扰的项目也已被提出,不过在以往的心理测量研究中从未被纳入。本研究的目的是创建NEQ - 16的意大利语版本(I - NEQ - 16),并纳入用于评估与夜食相关困扰的项目。该研究的一个主要目标是提出I - NEQ - 16的单维版本并研究其心理测量特性。482名意大利成年人(380名女性和102名男性;平均年龄 = 25.5岁,标准差 = 10.9岁)接受了NEQ的意大利语版本、夜食诊断问卷(NEDQ)以及测量暴饮暴食、情绪化和外部进食、昼夜节律类型、失眠以及焦虑和抑郁严重程度的问卷测试。为了提高I - NEQ - 16的单维性,我们在进一步分析中剔除了项目1、4和7,因为它们增加了测量的异质性。验证性因素分析表明修正后的单因素模型拟合良好,允许三对项目之间存在相关误差。I - NEQ - 16得分与所有同时进行测试的问卷得分均显著相关,并且能够根据NEDQ对个体的夜食症诊断进行分类。因此,I - NEQ - 16是一种有效的测量工具,可能有助于研究普通人群中夜食的相关因素。
