The aim of the present study was to explore similarities between men with MD, women with ED, and a control group of men with body related preoccupations, regarding self-esteem, body esteem, and personality traits. Analyses revealed that clinical groups reported lower body esteem, more perfectionism and narcissism than the control group; only the ED group showed a significantly lower selfesteem than the control group. Also, men with MD showed higher self-esteem and body-esteem, as well as a higher level of narcissistic grandiosity than women with ED. Even though, we cannot exclude that gender differences could partly explain these findings, the present results suggested that a preserved self-esteem and a heightened narcissistic grandiosity tend to characterize MD.

To better understand these associations, this study tested an explanatory model in which appearance-focused social media use, internalisation of social media pressure, and mindfulness abilities mediated the relationship between COVID-related distress and body dissatisfaction, which in turn was associated with dietary restraint and binge eating episodes. Methods: Adolescents (N =498, Mage= 16.7, 47.2% girls) recruited within high schools completed online measures. Results: A final well-adjusted model was revealed using path analyses, confirming the proposed mediational effects. Conclusions: Findings suggest that mindfulness, media use and the internalisation of social media pressure are potential key processes explaining body dissatisfaction and eating disorders among adolescents who experienced higher level of COVID-related distress.

Un échantillon de 968 adolescents âgés entre 12 et 18 ans a été recruté dans le cadre d’un projet de plus grande envergure. Les symptômes associés au TAH, au TDAH, ainsi que les traits d’impulsivité étaient mesurés respectivement par le Binge Eating Scale (BES), le Adult ADHD Self Report Scale (ASRS) et le UPPS Impulsive Behaviour Scale. Un questionnaire sociodémographique a été utilisé afin de pouvoir documenter le sexe, l'âge et l'IMC. Une corrélation positive et significative a été trouvée entre les symptômes du TDAH et ceux du TAH. Les facettes de l’urgence et du manque de persévérance sont ressorties comme étant des variables médiatrices de la relation entre les symptômes du TDAH et ceux du TAH. Ces résultats permettent d’...

In binge eating disorder (BED) and food addiction (FA), the extent of cognitive impairment is still unclear. This study aimed to characterize, among those with BED and FA, neurocognitive functions using performances based on neuropsychological tasks in the context of neutral stimuli in adults. METHOD MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews, CINAHL and gray literature (ProQuest and OpenGrey) were used to identify studies that reported neurocognitive assessments in BED or FA up to December 2019. A three-level meta-analysis was conducted. RESULTS A significant overall effect was found for global cognitive impairments, suggesting that individuals with BED or FA have poorer performances when completing cognitive tasks. Analyses for specific cognitive domains revealed that individuals with BED showed poorer performances at tasks assessing cognitive flexibility, inhibitory control, attention and planning. Analyses regarding FA were inconclusive due to a lack of studies. Thus, the results were described qualitatively. CONCLUSION Our meta-analysis highlighted the cognitive weaknesses that seem to come with BED and the necessity to integrate them in the assessment and treatment of this condition. It also stressed the lack of quality studies surrounding the cognitive features of FA.

A group of 25 adolescents (12–18 years; Mean age = 15.2 years) with a high level of FA symptoms (two and more) were compared to a control group without FA symptoms (n = 25), matched on sex and age, on four Cambridge Neuropsychological Test Automated Battery (CANTAB) neuropsychological tasks (MT: Multitasking Test; OTS: One Touch Stockings of Cambridge; SST: Stop Signal Task; RVP: Rapid Visual Information Processing). They were also compared on self-reported questionnaires assessing binge eating, depressive and anxiety symptoms, impulsivity levels, as well as executive functioning difficulties. Group comparisons did not show significant differences on neuropsychological tasks’ performances. However, effect sizes’ estimates showed small to medium effect sizes on three scores: adolescents with a high level of FA symptoms showed a higher probability of an err...

While psychological markers of FA have often been documented, data on physiological markers remains scarce. This study aimed to investigate HPA-axis functioning through cortisol awakening response (CAR) in relation to FA among bariatric candidates. We hypothesized that participants presenting high FA symptomatology would present a blunted CAR when compared to participants presenting low FA symptomatology and that significant associations between CAR and eating behaviors would be observed within both groups. The final sample comprised 40 participants, who were invited to complete questionnaires and provide saliva samples upon awakening (T0, T15, and T30). Results from the two-way ANOVA with repeated measures showed a non-significant “time x group” interaction, indicating that CAR did not differ between groups. Moreover, results from ...

The aim of this study was thus to explore the psychometric properties (factor structure, internal consistency, convergent and divergent validity) of the French version of the YFAS in a clinical sample, namely individuals suffering from severe obesity and awaiting bariatric surgery. Participants (N = 146; mean BMI = 48.29 kg/m 2) were recruited at the Quebec Heart and Lung Institute (Canada) during their pre-operative visit. They were asked to complete questionnaires, including the YFAS. Factorial and correlational analyses were performed. Some items had to be removed from the factorial analysis due to a lack of variability (#4, #10, #11, #12, and #22) and low factor loading (#24). The analysis conducted on the remaining 16 items revealed a one-factor structure, with factor loadings higher than .30 and excellent internal consistency (α = .92). The present findings are consistent with previous validation studies of samples presenting obesity and support the use of a 16-item version of the French YFAS among bariatric candidates. However, the need for further investigation remains important in order to better assess the stability of the instrument when used in clinical samples.

Our project focused on developing a learning environment that fosters resident education in quality improvement and patient safety.MethodsA multidisciplinary team developed a survey to assess baseline perceptions of quality improvement tools and training and resident participation in quality improvement and patient safety programs. We then developed a curriculum to address deficiencies. The curriculum paired residents with faculty. At the completion of the first curriculum cycle, we asked faculty and residents to complete the same survey.ResultsOur pilot survey revealed a need for a comprehensive program to teach faculty and residents the art of teaching. Our follow-up study showed an increase in the number of residents and faculty who reported that their programs were extremely or very good at providing tools to develop skills and habits to practice quality improvement. We also had a statistically significant decrease (15.8%, P=0.0128) in faculty who reported their program as not at all effective at providing resident quality improvement tools and skills. Among residents and faculty, we had a 12% (P=0.2422) and a 38.2% (P=0.0010), respectively, improvement in reported monthly resident involvement in quality improvement and patient safety projects.ConclusionWe demonstrated that developing a sustainable and practical faculty development program within a large academic medical center is feasible. Our postimplementation survey demonstrated an improvement in perceived participation in quality improvement, patient safety, and faculty development among faculty and residents. Future targets will focus on sustaining and spreading the program to all faculty and residents in the institution.
