Abstract
Background Restless legs syndrome (RLS) is a complex sensorimotor disorder occurring with a typical circadian fashion. Association with additional features, like alexithymia and nocturnal compulsive behaviors further complicates the framework. Objectives To assess interoception in RLS. Methods A total of 25 RLS patients and 28 controls underwent the heartbeat tracking task (interoceptive accuracy [IAC]). RLS symptoms' frequency, disturbance and duration, nocturnal behaviors, interoceptive awareness (IAW), alexithymia, depressive and anxiety symptoms were also collected. Results RLS patients showed significant lower IAC (P = 0.0003) and IAW (P = 0.012), and reported more nocturnal eating behaviors (P < 0.001). IAC positively correlated with IAW (R = 0.32), and negatively correlated with age (R = -0.58). Nocturnal eating behavior negatively correlated with IAC (R = -0.44) and IAW (R = -0.50). Conclusions RLS patients presented reduced interoceptive abilities correlating with higher nocturnal eating behaviors. Future studies are needed to explore the role of interoception in RLS pathophysiology, also in relation to other sensorimotor aspects.

Kaur J, Dang AB, Gan J, An Z, Krug I. Night Eating Syndrome in Patients With Obesity and Binge Eating Disorder: A Systematic Review. Front Psychol 2022; 12:766827. [PMID: 35069340 PMCID: PMC8766715 DOI: 10.3389/fpsyg.2021.766827] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 12/06/2021] [Indexed: 12/22/2022] Open
Abstract
Night eating syndrome (NES) is currently classified as an Other Specified Feeding or Eating Disorder (OSFED) under the Diagnostic Statistical Manual−5 (DSM-5). This systematic review aims to consolidate the studies that describe the sociodemographic, clinical and psychological features of NES in a population of patients with eating disorders (ED), obesity, or those undergoing bariatric surgery, and were published after the publication of the DSM-5. A further aim was to compare, where possible, NES with BED on the aforementioned variables. Lastly, we aimed to appraise the quality of the studies being included in the review. We conducted a systematic search on three databases (MEDLINE, PubMed and Embase) which resulted in the selection of 22 studies for the review. We included the articles that studied patients with NES and their sociodemographic, clinical and psychological features in a clinical (i.e., ED, obese or bariatric surgery) population, through a quantitative study design. Articles were excluded if the NES patients included in the study had a comorbid psychological disorder, and/or the sample was collected from a university/non-clinical population, and/or the study design was qualitative, and/or NES features were compared with any other disorder, except BED. Our study found that no conclusions about the link between any sociodemographic feature (such as, age, gender, income, etc.) and an NES diagnosis could be made. Further, NES patients presented with elevated ED pathology (including emotional eating and loss of control eating) and higher occurrence of depressive symptoms than controls. Contrary to the literature suggesting that NES and Binge Eating Disorder (BED; an ED subtype which is also comorbid with obesity) patients often report overlapping features, questioning the validity of NES as an ED diagnosis, we found that BED can be differentiated from NES by the higher occurrence of emotional eating, body related concerns and abnormal eating episodes. The review also suggested an overlap between NES and Sleep-Related Eating Disorder. We recommend that it is essential to study NES as an independent disorder to further develop its diagnostic criteria and treatment options, thereby, increasing the quality of life of the patients suffering from this syndrome.

Abstract
Alexithymia, a difficulty identifying and expressing emotions experienced by oneself or others, measurably harms quality of sleep. Research has observed the association between alexithymia and sleep problems; however, the cumulative effect of this association is still unknown. Therefore, this systematic review and meta-analysis was conducted to present scientific evidence regarding the relationship between alexithymia and sleep quality. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, and using relevant keywords, we searched six databases: Scopus, PubMed Central, ProQuest, ISI Web of Knowledge, EMBASE, and Science Direct. We selected observational studies on the association between alexithymia and sleep. We conducted meta-analysis using a random-effect model to calculate the effect size (ES) with Fisher's z transformation. Eligible studies (N = 26) in 24 papers included 7546 participants from 12 countries. The entire ES for the association between alexithymia and sleep was 0.44 (95 % CI: 0.31, 0.56). Additionally, patient populations had a larger ES (ES = 0.55; 95 % CI: 0.30, 0.79) than healthy populations (ES = 0.30; 95 % CI: 0.20, 0.41). The results of the present systematic review and meta-analysis revealed a significant association between alexithymia and sleep problems, especially among people with any medical condition.

Abstract
Context: Patients with eating disorders (EDs) may have a lower mentalization ability. To the best of our knowledge, no meta-analysis has so far addressed the multidimensional mentalization profile within these patients.Objective: To summarize the existing evidence of the mentalization profile and its association with EDs.Data sources: We searched for articles in PsychINFO, Embase and PubMed using the search terms mentalization, reflective function, adult attachment interview, alexithymia, Toronto Alexithymia Scale, eye test, Reading the Mind in the Eyes Test, Theory of Mind, mind-mindedness, mind-blindness, facial expression recognition, metacognition, ED, anorexia nervosa (AN) and bulimia nervosa (BN).Studies included: Quantitative studies including diagnosed patients with an ED, healthy controls (HCs) and relevant test methods.Data synthesis: Forty-four studies were included. Nine studies were eligible for the meta-analysis. Significantly lower mentalization ability about oneself was found in patients with an ED when compared to HCs. Groups were more comparable when dealing with mentalization ability of others. Non-significant but clinically relevant results include a tendency for a lower mentalization ability in patients with AN compared to patients with BN.Conclusion: The mentalization profile is complex and varies across dimensions of mentalization in patients with an ED. Different degrees of mentalization between various EDs were found, implying the necessity for further research on mentalization profiles in different ED diagnoses. The sparse existing literature was a limitation for this meta-analysis, emphasizing that further research on the mentalization profile in patients with EDs is needed.

Preliminary Validation of the Italian Night Eating Questionnaire (I-NEQ-16): Item Analysis and Factor Structure. Front Psychol 2018; 9:2628.

Abstract
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.

Abstract
Night Eating Syndrome (NES), as a diagnosis, presents as a combination of disordered eating, sleep and mood. Patients identified as having both NES and obesity demonstrate poorer outcomes in terms of weight loss compared to those with NES only. However, research focusing on psychological factors associated with NES remains relatively underdeveloped. This study aimed to explore the relationship between NES and the experience of emotion from the perspective of patients accessing a weight management service. Ten adults who met diagnostic criteria for moderate or full NES took part in a semi-structured interview. Data were analysed using a constructivist approach to grounded theory. A core concept to emerge from the analysis was termed 'emotional hunger'; reflecting an urge or need to satiate a set of underlying unmet emotional needs. It was underpinned by the following interrelated themes: (1) Cultivating a dependency on food; (2) Relying on food to regulate emotions; (3) Understanding the significance of night-time; (4) Acknowledging the consequences of night eating. This study provides an in-depth understanding of the relationship between NES and the experience of emotion from the perspective of patients attending a weight management service. Results have potential to inform future service development, particularly around the adoption of a more holistic approach to night eating behaviours.

Abstract
OBJECTIVE To evaluate the relation between alexithymia and Referential Activity (RA), a linguistic measure of the process by which non-verbal emotional experience is connected to language. METHODS The 20-Item Toronto Alexithymia Scale (TAS-20) and the Toronto Structured Interview for Alexithymia (TSIA) were administered to 20 postgraduate students and 15 outpatients with hypertension. The Weighted Referential Activity Dictionary (WRAD) and other linguistic measures (Reflection, Disfluency, and Somatic Sense) were applied to texts derived from the TSIA using the Discourse Attributes Analysis Program (DAAP). RESULTS Multiple linear regressions performed in the whole sample showed a relation between TSIA scores and Somatic Sense. Comparing the two groups, hypertensive subjects yielded higher scores on the TSIA than the young adult sample; no differences in DAAP measures emerged. A significant negative correlation was found between the TAS-20 Difficulty Describing Feelings score and the DAAP measure of references to body activations (Somatic Sense) both in the young adult sample and in hypertensives. In the young adult sample, negative relations emerged between different TSIA factors, WRAD score, and Somatic Sense; a positive relation with fragmented speech (Disfluency) and use of rationalization (Reflection) was also found. In hypertensive subjects, using the TSIA, a negative correlation between alexithymia and Somatic Sense and a positive correlation between alexithymia and the Mean High WRAD (a measure of intensity of engagement during the speech) were found. CONCLUSION The TSIA seems to be a more adequate instrument than the TAS-20 to explore relations between alexithymia and RA. Results appear to suggest a complex, nonlinear relation between alexithymia and RA, presumably influenced by subject-specific characteristics. PRACTITIONER POINTS A relation between alexithymia and RA has been proposed on theoretical grounds, but there has been minimal empirical investigation. This was the first study to employ both a self-report measure and a structured interview for measuring alexithymia in relation to RA. The results of this study suggest a complex, nonlinear relation between alexithymia and RA; this finding is essentially obtained with the structured interview measure of alexithymia. This relation is presumably influenced by subject-specific characteristics.
