“…Consistent with the results of previous studies which administered the NEQ-14 (Vander Wal, 2012; Aloi et al, 2017), I-NEQ-16 scores were significantly associated with concurrent scores for binge eating, emotional and external eating, depressive and anxiety symptoms, and sleep-related problems (i.e., nocturnal chronotype and insomnia severity). Considering that NES is frequently comorbid with binge eating (Napolitano et al, 2001; Grilo and Masheb, 2004; Colles et al, 2007; Allison et al, 2008; McCuen-Wurst et al, 2018) and that binge eating severity has been associated with emotional psychopathology (Bulik et al, 2002) and insomnia (Kenny et al, 2018), we also calculated partial correlations between the I-NEQ-16 and concurrent measures, while controlling for the effect of binge eating severity, and found that this variable was not able to account for all the associations night eating severity has with anxiety, depression, and sleep-related problems (Runfola et al, 2014). Furthermore, the BMI score was weakly but statistically significantly associated with I-NEQ-16 scores only after controlling for the effect of binge eating severity.…”

Preliminary Validation of the Italian Night Eating Questionnaire (I-NEQ-16): Item Analysis and Factor Structure

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, SD = 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.

“…All procedures were approved by the regional health research ethics board. Recruitment procedures are reported elsewhere (Kenny, Singleton, & Carter, 2017;Kenny, Van Wijk, Singleton, & Carter, 2018). Briefly, individuals with BED and NED were recruited from the community via social media, radio interviews, and posters.…”

Objective Research suggests that overvaluation of weight and shape is a clinical feature in binge‐eating disorder (BED). However, this construct has been differentially defined in the literature even when using the same measure. Here we compare two cut‐offs that have previously been used to differentiate clinical and subthreshold overvaluation using the EDE‐Q. Method Individuals with BED (n = 72, 93% female) and no history of an eating disorder (NED; n = 21, 91% female) completed measures of eating disorder (ED) and general psychopathology online. Individuals with BED were categorized as having clinical or subthreshold overvaluation using two different cut‐offs used in previous studies. The clinical, subthreshold, and NED groups were compared on ED and general psychopathology. The association between overvaluation and psychopathology was also assessed in the BED and NED groups. Results The two cut‐offs yielded identical results, with individuals in the clinical overvaluation group reporting greater ED psychopathology than those in the subthreshold and NED groups. When considered as a continuous variable, overvaluation was a significant predictor of both ED‐related and general psychopathology. Discussion The two cut‐offs yielded identical results, likely due to the high internal consistency between overvaluation items. Under such circumstances, the use of either cut‐off seems appropriate. However, given the associations reported in the regression analyses, we propose that considering overvaluation as a dimensional variable, rather than a categorical one, may have greater utility.

“…In a recent study, Kenny et al [60] showed that BED patients reported significantly greater insomnia symptoms than individuals without BED and that this relationship was partially and fully mediated by anxiety and depressive symptoms. This may imply that poor sleep that BED patients experience is related to mood.…”
