Filter by:Specific aims are to: 1. Assess variability in performance on state-level measures of working memory (WM) delivered via Ecological Momentary Assessment (EMA). The investigators expect WM performance to vary over the course of a day across participants, and to be poorer and more variable among youth with overweight/obesity and loss of control (LOC) eating relative to overweight/obese and non-overweight controls. 2. Investigate the relationship between state WM and eating behavior. The investigators expect that poorer momentary WM will predict an increased likelihood of LOC eating as assessed via EMA, and greater energy intake and poorer dietary quality as assessed via dietary recall, across participants. The investigators expect these effects to be strongest among youth with concomitant overweight/obesity and LOC eating.
Loss of control (LOC) eating in children is associated with multiple physical and mental health impairments, including obesity and eating disorders. Little is known about the developmental neurobiology of LOC, which is crucial to specifying its pathophysiology and the development of effective preventive interventions. Individual differences in working memory (WM) appear to be related to LOC eating and excess weight status in youth, but the specificity and neural correlates of these individual differences are unclear. Failure to adequately understand the nature of associations between WM and eating behavior in children with overweight/obesity limits the development of appropriately-targeted, neuro-developmentally informed interventions addressing problematic eating and related weight gain in youth. To close this clinical research gap, the current study proposes to investigate the context-dependence of WM impairment and its neural correlates in children with concomitant overweight/ obesity and LOC eating as compared to their overweight/obese peers. Specific aims are to investigate: 1)WM performance in youth with LOC eating relative to overweight/obese controls during recalls in the context of food-related versus neutral distractors; and 2) neural activation patterns during WM performance across both food-related and neutral stimuli. We hypothesize that, relative to their overweight/obese peers, youth with LOC eating will show 1) more errors and slower response times during recalls involving food-related vs. neutral distractors, and fewer errors and faster response times during recalls involving food-related vs. neutral targets; 2) increased activation in prefrontal regions during WM performance across stimuli types relative to overweight/obese controls, and 3) even greater activation in the context of food-related versus neutral distractors. The proposed study is the first to use state-of-the-science neuroimaging methodology to clarify the relations between WM and LOC eating, with strong potential to advance understanding of the associations among executive functioning, excess weight status, and eating pathology, and inform the development of interventions (e.g., WM training) to alleviate their cumulative personal and societal burden.
This study will develop and test a cognitive-behavioral intervention for adolescents with binge/loss-of-control eating.
The purpose of this study is to test a novel treatment for binge eating that will be compared to a waitlist control group. The investigators are seeking to target factors that might influence binge eating by increasing reward in non-food life domains. The treatment is weekly for 10 weeks and will take place at Drexel University in Philadelphia.
Executive functions are part of the high-level cognitive processes essential to the proper functioning of human cognition. They consist mainly of flexibility, updating and inhibition. Some studies have shown a correlation between executive disorders (impaired executive function) and psychiatric disorders such as obsessive-compulsive disorder or phobias. These executive disorders are related to dysfunctions of the fronto-striatal loops. In addition, other studies have investigated the link that may exist between eating disorders such as anorexia or bulimia nervosa and executive functioning. Anorexia nervosa, bulimia nervosa and binge eating disorders are eating disorders characterized by a dysfunction in food intake with restriction of food or compulsions as well as strong concerns about the body schema. Concerning the executive functioning, these studies highlight a lack of cognitive flexibility for patients with anorexia nervosa and bulimia nervosa but also dysfunctions depending on the type of pathology (anorexia nervosa or bulimia nervosa). These studies also highlight the beneficial effects of cognitive remediation on people with eating disorders. However, the investigation of the inhibitory control has not yet been specifically studied. Moreover, since eating disorders are structurally different, a comparison between several pathologies would be interesting to consider. The aim of this study is to determine if a dysfunction of inhibitory control can be highlighted in people with eating disorders. This study would also allow further researches about cognitive remediation suitable for the specific difficulties encountered in these diseases.
This study will evaluate the degree to which engaging targets produces a desired change in medical regimen adherence (across 4-week interventions) and health behavior among smokers (n=50) and overweight/obese persons with binge eating disorder (n=50) (smoking in the former sample and binge eating in the latter sample). The investigators will employ a novel mobile behavioral assessment/intervention platform to engage targets in these samples, given that (1) it offers self-regulation assessment and behavior change tools via an integrated platform to a wide array of populations, and (2) content within the platform can be quickly modified as needed to better impact targets. This is the fourth and final phase of a study that aims to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes. This trial builds on NCT03352713.
This study aims to develop and evaluate the efficacy of a behavioral weight loss treatment approach for individuals with binge eating disorder to both reduce their binge eating behaviors and lose weight.
This study will evaluate the extent to which we can engage and manipulate putative targets within the self-regulation domain within and outside of laboratory settings in samples of smokers and overweight/obese individuals with binge eating disorder. This is the fourth phase of a study that aims to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes.
Mood and circadian rhythm disruptions are associated with binge eating (BE). BE is a discrete, episodic behavior characterized by 1) eating an objectively large amount of food and 2) experiencing a subjective sense of loss of control. BE episodes are often preceded by negative mood states, and a subtype of individuals with BE has high levels of negative moods. This group has more comorbid psychopathology and a poorer response to treatment. Thus, understanding the role of negative mood is a critical area for research on BE. Individuals with BE demonstrate disruptions in several circadian rhythms, including diurnal meal timing, hormone patterns (e.g., daily cortisol rhythms), and mood variations. The most potent synchronizer of circadian rhythms is light. Thus, exposure to light may explain other phenomena that fluctuate similarly, such as mood and the occurrence of BE. Mood is subject to the influence of light, and BE is also influenced by exposure to bright light. It is unknown whether regulating circadian rhythms via regular exposure to light improves BE through its effects on mood or via changes in other biological or behavioral rhythms. This knowledge can inform the development of treatments targeting biobehavioral mechanisms that maintain BE and indicate for whom this may be most effective. This project aims to test the roles of negative mood and circadian rhythms in the relationship between light exposure and BE and identify subtypes of individuals in whom this effect is strong. The investigators hypothesize that individuals exposed to less natural bright light will experience more frequent BE, more negative mood, and a blunted morning cortisol response. The investigators further hypothesize that manipulating exposure to artificial bright light will reduce the frequency of BE and negative mood and increase the morning cortisol response. Finally, the investigators hypothesize that the effects of this artificial bright light exposure on BE frequency will be mediated by changes in negative mood, which itself will be accounted for by changes in circadian rhythms as indicated by the morning cortisol response. Additionally, the investigators have two moderation hypotheses: that the effects of artificial bright light exposure on BE will be greater for those who fit the high negative mood type than those who do not and that the effects will be greater for individuals with a blunted morning cortisol response at baseline than for those without.
The study seeks to evaluate the acceptability, feasibility, target engagement, and validity of an innovative smartphone application with ecological momentary interventions to augment cognitive behavioral therapy for bulimia nervosa.
