Noradrenergic control of neurobehavior in human binge-eating disorder and obesity (NOBEAD): A smartphone-supported behavioral emotion regulation intervention study protocol integrating molecular brain imaging. Int J Eat Disord 2024; 57:206-220. [PMID: 37941314 DOI: 10.1002/eat.24080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 09/29/2023] [Accepted: 09/29/2023] [Indexed: 11/10/2023]
Abstract
OBJECTIVE The neurobehavioral underpinnings of binge-eating disorder (BED), co-occurring with obesity (OB), are largely unknown. This research project conceptualizes BED as a disorder with dysfunctional emotion regulation (ER) linked with changes in central noradrenaline (NA) transmission and NA-modulated neuronal networks. METHODS We expect abnormalities in NA activity in both BED and OB, but most pronounced in BED. We expect these abnormalities to be modifiable through state-of-the-art ER intervention, specifically in BED. To assess the role of NA transmission, we will quantify changes in NA transporter (NAT) availability using the highly NAT-specific [11 C]methylreboxetin (MRB) and positron emission tomography-magnetic resonance imaging (PET-MRI) that allows measuring molecular and neuronal changes before and after an ER intervention. Individual 12-session smartphone-supported acceptance-based behavioral therapy will be conducted to improve ER. Thirty individuals with OB and BED (OB + BED), 30 individuals with OB without BED (OB - BED), and 20 individuals with normal weight will undergo assessments of NAT availability and neuronal network activity under rest and stimulated conditions, clinical interviews, self-report questionnaires on eating behavior, ER, mental and physical health, and quality of life, and neuropsychological tests on executive function. Afterwards, in an experimental randomized-controlled design, individuals with OB + BED and OB - BED will be allocated to smartphone-supported ER intervention versus a waitlist and re-assessed after 10 weeks. DISCUSSION By obtaining biological and behavioral markers, the proposed study will disentangle the involvement of NAT and the central NA system in the modulation of emotion-supporting neuronal networks that influence eating behavior. Neurobehavioral mechanisms of change during an ER intervention will be determined. TRIAL REGISTRATION German Clinical Trials Register (DRKS): DRKS00029367. PUBLIC SIGNIFICANCE This study investigates the central noradrenaline system by using hybrid brain imaging in conjunction with emotion regulation as a putative core biological mechanism in individuals with obesity with or without binge-eating disorder that is targeted by emotion regulation intervention. The results will provide a molecular signature beyond functional imaging biomarkers as a predictive biomarker toward precision medicine for tailoring treatments for individuals with binge-eating disorders and obesity.

Abstract
OBJECTIVE Despite the increasing popularity of neurofeedback (NF), aiming at voluntary modulation of dysfunctional prefrontal cortex (PFC) signals in the treatment of binge-eating disorder (BED) and/or overweight, mechanisms remain poorly understood. METHODS Based on a randomized-controlled trial offering 12 food-specific real-time functional near-infrared spectroscopy (rtfNIRS)-NF sessions to participants with BED (n = 22), this preregistered study examined (1) online regulation success as predictor for offline regulation success, defined by PFC signals during regulation versus watch, and subjective regulation success, and (2) changes in loss of control (LOC) eating after vs. before and across 12 rtfNIRS-NF-sessions. RESULTS Higher online regulation success expectedly predicted better subjective, but worse offline regulation success. LOC eating decreased after vs. before, but not over rtfNIRS-NF-sessions, and was not associated with subjective or offline regulation success. CONCLUSIONS The association between online and subjective regulation success confirmed the presumed mechanism of operant conditioning underlying rtfNIRS-NF-learning. The contrary association between online and offline regulation indicated differential PFC involvement upon subtraction of automatic food-specific responses from regulation signals for offline success. Decreased LOC eating after food-specific rtfNIRS-NF-sessions suggested the potential of NF in BED treatment. SIGNIFICANCE Results may guide the optimization of future NF studies in larger samples with BED.

Abstract
OBJECTIVE Low reward response to conventionally rewarding stimuli and high reward response to food (i.e., reward imbalance), has been supported as a maintenance factor for eating disorders characterized by binge eating. The current study was a pilot randomized controlled trial testing a novel treatment approach for binge eating targeting reward imbalance, called Reward Re-Training (RRT), in comparison to a therapeutic attention control condition (supportive psychotherapy; ST). METHOD Fifty-nine participants were randomly assigned to receive either 10 group sessions of RRT or ST via videoconferencing software. Assessments of eating pathology and hypothesized treatment targets were completed at pretreatment, mid-treatment, and posttreatment, and 3-month following the end of treatment. RESULTS Feasibility and acceptability success benchmarks were achieved. Results found a significant indirect effect of RRT on lower posttreatment global eating pathology through decreases in reward to food from pretreatment to mid-treatment. No significant differences were observed between groups in terms of change in hypothesized treatment mechanisms or outcomes at posttreatment or 3-month follow-up. DISCUSSION The current study supports the feasibility and acceptability of RRT, and the preliminary efficacy of both RRT and ST. Further research comparing these approaches to CBT would help to inform who might benefit from non-CBT based treatment approaches. PUBLIC SIGNIFICANCE The current pilot study supports the feasibility and acceptability of Reward Re-Training (RRT) as a treatment for binge eating (BE). RRT produced large, but similar, reductions in overall eating pathology and BE frequency compared to supportive psychotherapy (ST) by 3-month follow-up. This study supports further testing of indirect treatments such as RRT for binge eating.

Experiencing eight psychotherapy approaches devoted to eating disorders in a single-day workshop increases insight and motivation to engage in care: a pilot study. Eat Weight Disord 2022; 27:2213-2222.

Abstract
PURPOSE For patients with eating disorders (EDs), early engagement in care is usually considered a positive prognostic factor. The aim of the study was to investigate how a single-day intervention devoted to early, brief, experiential exposure to a variety of psychotherapy approaches might support commitment to change and the decision to engage in care in patients with EDs. METHODS One hundred and sixty-nine adult outpatients newly diagnosed with an ED took part in a single-day workshop for groups of up to ten patients, where they experienced eight psychotherapeutic approaches. Motivation to change care and level of insight were assessed at baseline and 10 days after the intervention. RESULTS Motivation and commitment to take active steps toward change (expressed by the "Committed Action" composite score) significantly improved after the intervention (p < 0.001), and a significant number of patients specifically moved from "contemplation" to "action" stage (p < 0.001). The improvement of motivation to change was significantly associated with an increase in insight capacity (p < 0.001), and this increase was observed for almost all related dimensions such as recognition of illness or awareness of need for psychological treatment. CONCLUSION A single-day session devoted to experiencing a range of group psychotherapies increased patients' insight and motivation to actively engage in care. To confirm potential longer-term benefits of this intervention, further studies are needed to explore the contribution of each approach and process specifically involved in patients' increased motivation for care, as well as the clinical characteristics of patients associated with better outcomes. LEVEL OF EVIDENCE V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Abstract
BACKGROUND Distress tolerance (DT) has received increased attention in recent years due to its purported role in dysregulated behaviours and their clinical manifestations, such as problematic substance use (PSU), disordered eating behaviours (e.g., binge-eating and purging; DEB), and borderline personality disorder (BPD) symptomatology. Despite the proposed transdiagnostic utility of DT across PSU, DEB, and BPD, there has yet to be a systematic and comprehensive examination characterising and comparing its association with this class of impulsive-type psychopathology. METHODS A systematic search was conducted across five electronic databases using search terms designed to capture extant literature on the association between DT and PSU, DEB, and BPD symptomatology. A series of meta-analyses were undertaken on correlation coefficients from 81 studies to examine the association between DT and each psychopathology domain, as well as impulsive-type psychopathology overall. Moderator analyses were conducted to examine whether these relationships were moderated by DT measurement type, sample type, age, and gender. RESULTS DT shared significant, negative, medium correlations with PSU (r = -.18,), DEB (r = -.20), and BPD symptomatology (r = -.27). The magnitude of these associations was not significantly different across the three psychopathology domains, supporting transdiagnostic conceptualisation. DT measurement type, age, and sample type moderated several of these indicated relationships. LIMITATIONS The majority of studies were conducted in adult samples from Western countries, limiting understanding of these relationships across development and different cultures. CONCLUSIONS The present findings support the putative transdiagnostic role of DT across PSU, DEB, and BPD, which may ultimately inform novel, cross-cutting interventions.

Abstract
Background Previous theoretical models and reviews have documented a strong connection between emotion dysregulation eating disorder (ED) psychopathology among the general and clinical populations. The aim of this review was to build on this previous work by conducting a network meta-analysis to explore associations between adaptive and maladaptive emotion regulation strategies and ED psychopathology trans-diagnostically across the ED spectrum to identify areas of emotion dysregulation that have the strongest association with symptomatology. Methodology A total of 104 studies were included in the meta-analysis and correlation coefficient representing the associations between specific emotion regulation strategies and ED symptomatology were extracted. We ran a Bayesian random effects network meta-analysis and the initial network was well-connected with each emotion regulation strategy being linked to at least one other strategy. We also conducted a network meta-regression to explore whether between-study differences in body mass index (BMI), age, and whether the sample consisted of solely female participants explained any possible network inconsistency. Results The network meta-analysis revealed that ruminations and non-acceptance of emotions were most closely associated with ED psychopathology. There was no significant network inconsistency but two comparisons approached significance and thus meta-regressions were conducted. The meta-regressions revealed a significant effect of BMI such that the associations between different emotion regulation strategies and ED symptomatology were weaker among those with low BMI. Discussion The present findings build on previous work and highlight the role of rumination and difficulties with accepting emotions as key emotion regulation difficulties in EDs. Additionally, the finding that the associations were weaker among ED patients with low BMI may point toward a complex relationship between ED behaviors and emotion regulation. Taken together, our findings call for interventions that target emotion regulation, specifically rumination and difficulties accepting emotions, in the treatment of EDs.

Abstract
OBJECTIVE Long-term effectiveness is a critical aspect of the clinical utility of a treatment; however, a meta-analytic evaluation of psychological and medical treatments for binge-eating disorder (BED), including weight loss treatments, is outstanding. This meta-analysis sought to provide a comprehensive evaluation of the long-term effectiveness in diverse treatments for BED regarding a range of clinically relevant outcomes. METHOD Based on a systematic search up to February 2018, 114 published and unpublished randomized-controlled (RCTs), nonrandomized, and uncontrolled treatment studies, totaling 8,862 individuals with BED (DSM-IV, DSM-5), were identified and analyzed using within-group random-effect modeling. RESULTS Effectiveness (regarding binge-eating episodes and abstinence, eating disorder and general psychopathology) up to 12 months following treatment was demonstrated for psychotherapy, structured self-help treatment, and combined treatment, while the results regarding body weight reduction were inconsistent. These results were confirmed in sensitivity analyses with RCTs on the most common treatments-cognitive-behavioral therapy and self-help treatment based on this approach. Follow-up intervals longer than 12 months were rarely reported, mostly supporting the long-term effectiveness of psychotherapy. Few follow-up data were available for pharmacotherapy, and behavioral and self-help weight loss treatment, while follow-up data were lacking for pharmacological and surgical weight loss treatment. Study quality varied widely. DISCUSSION This comprehensive meta-analysis demonstrated the medium-term effectiveness of psychotherapy, structured self-help treatment, and combined treatment for patients with BED, and supported the long-term effectiveness of psychotherapy. The results were derived from uncontrolled comparisons over time. Further long-term high quality research on psychological and medical treatments for BED is required.

Abstract
Obesity coupled with binge eating disorder (BED) is an increasing problem. Incorporation of treatment strategies that address both problems in people with comorbid symptoms is of major interest. This study aimed to investigate the feasibility and preliminary long-term outcomes of a brief emotion-focused cognitive behavioral therapy (EF-CBT) program. Seven out of 10 women with obesity and BED completed the intervention. Standardized outcome measures to assess the intensity of distress caused by complaints, psychological distress, emotional processing, eating behavior, and weight loss were completed at baseline, end-of-treatment, 6- and 18-month follow-ups. Individualized outcome measures were also applied to describe the personal experiences during the intervention. Findings suggest the program's long-term efficacy for improving psychological distress, emotional processing, and alexithymia. Positive reliable changes in emotional processing and alexithymia were observed in almost all participants. The mean intensity of distress caused by complaints also decreased at the end of the intervention, with a large effect size (d = 0.89). Reliable changes in these outcome measures were observed at all time-points, despite the mean scores for the 18-month follow-up suggest a retraction in improvement. Weight loss was below expectations at all time-points, as were changes in emotional and external eating. Restrained eating mean scores remained stable throughout the study. Participants perceived the program to be useful in improving emotional awareness and eating control. Program feasibility was supported by the retention rate (70%) and the average number of attended sessions (M = 9.71; SD = 2.06). Further studies are needed to examine the effectiveness of EF-CBT interventions.

Abstract
Binge eating (BE; i.e., the consumption of a large amount of food in a discrete time period, accompanied by a sense of loss of control) is highly comorbid with overweight or obesity and is the primary symptom of binge eating disorder (BED). Current gold-standard treatment for BED (i.e., CBT) does not produce meaningful weight loss, thus failing to address a critical treatment target. This article describes the development of a novel acceptance-based behavioral treatment (ABBT) for individuals with clinically significant BE desiring to reduce BE symptoms and achieve concurrent weight loss. We discuss the development and structure of the novel treatment approach, and describe the test of a proof of concept version of the treatment in a clinical case series of four individuals. In the context of each clinical case description, we present initial acceptability of the treatment and challenges faced in treatment development and delivery. Finally, we discuss future research directions for the treatment, which could improve BE symptoms and weight loss outcomes for individuals with BE pathology.

Abstract
Eating disorders are serious psychiatric illnesses with high rates of morbidity and mortality. Effective treatments have traditionally included behaviorally focused therapies as well as several medication strategies. Recent years have seen promising developments in these treatments, including additional support for family-based approaches for children and adolescents, new evidence for "third-wave" behavioral therapies, and new support for the use of lisdexamfetamine for binge eating disorder and olanzapine for anorexia nervosa. Case study and pilot data are beginning to show limited support for neuromodulatory interventions targeting brain regions thought to be involved in eating disorders. This review summarizes treatment developments over the last several years and points towards future directions for the field.

Trait body image flexibility as a predictor of body image states in everyday life of young Australian women. Body Image 2019; 30:212-220. [PMID: 31377478 DOI: 10.1016/j.bodyim.2019.07.006] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 07/17/2019] [Accepted: 07/17/2019] [Indexed: 10/26/2022]
Abstract
The present study evaluated whether individuals with varying levels of trait body image flexibility differ in the severity, variability, and correlates of state body dissatisfaction experienced in their daily lives. One hundred and forty-seven women completed a baseline measure of trait body image flexibility, followed by a 7-day ecological momentary assessment phase in which participants self-reported state body dissatisfaction, disordered eating behavior, drive for thinness, and appearance comparisons at 10 semi-random intervals daily. Higher trait body image flexibility predicted lower average scores, less frequent reporting of high state body dissatisfaction, and less variability in their state body dissatisfaction ratings. Individuals with higher trait body image flexibility were also less likely to engage in a range of behaviors and cognitions previously shown to produce body dissatisfaction, including upward appearance comparisons, drive for thinness, binge eating, and dieting. However, few of these state-based relationships involving body dissatisfaction and these related behaviors and cognitions were moderated by trait body image flexibility. Overall, this pattern of findings suggests that body image flexible individuals may have less negative body image because they are less inclined to engage in behaviors and cognitions in their daily lives that encourage negative body image.

Abstract
Socially prescribed perfectionism (SPP) is often considered as a key risk factor for disordered eating (DE). However, current conceptualizations of SPP largely assume that this perfectionism pressure is non-specific (i.e., a global pressure), despite research indicating that for females experiencing DE, female-dominated groups impose this pressure (as a perceived norm). Furthermore, this relationship may be mediated by a negative reaction to this pressure, in the form of impulsivity (or negative urgency). To date, no research has investigated whether the relationship between SPP and DE is mediated by negative urgency, nor has there been research clarifying how in-group identification relates to DE, independent of SPP and negative urgency. To address these gaps, we assessed these variables in 147 female dieters (Mage = 25.12 years, SD = 3.08) using a cross-sectional design. Consistent with our hypotheses, negative urgency fully mediated the link between female-based SPP and disordered eating, while female-based in-group affect (identification) was predictive of disordered eating (although the latter relationship was not sustained in a multiple regression model). These findings suggest that the SPP from other women may relate to DE through increasing negative urgency, and that the link between in-group (female) affect and DE may be better explained by SPP's link to DE.

Abstract
Binge eating disorder (BED), characterized by recurrent episodes of binge eating with a subjective experience of lack of control, is the world’s most common eating disorder. The aim of the present pilot study was to examine the feasibility of implementing nature-based therapy (NBT) in the treatment of BED. The NBT intervention was compared to Support Group Meetings (SGMs), which are the only publicly available form of support for people diagnosed with BED in Denmark. Twenty participants with a BED diagnosis were included in the study, which had a mixed-methods design including Eating Disorder Examination interviews, semi-structured interviews, and questionnaires measuring well-being (The Psychological General Well-Being Index) and self-esteem (Rosenberg’s Self-Esteem Scale). Both the NBT and the SGMs showed positive results on all outcome measures (decreases in binge eating episodes and increases in general psychological well-being and self-esteem). The interviews indicated that the NBT context made the psychotherapeutic content more accessible to the participants and further helped them transfer the therapeutic gains to daily life after completing treatment. However, these results should be interpreted with caution due to the small sample size—ideally, they would need to be tested on a larger, randomized sample.

Abstract
Cognitive behavioral therapy (CBT) is regarded as the gold-standard treatment for bulimia nervosa (BN), yet despite impressive empirical support for its effectiveness, over 50% of patients fail to achieve abstinence from binge eating and purging by the end of treatment. One factor that may contribute to reduced efficacy rates in CBT is weight suppression (WS; the difference between a person's highest weight ever at their adult height and current weight). A growing body of research indicates that WS in patients with BN may have a clinically significant effect on symptomatology and prognosis. However, the current cognitive behavioral framework for BN does not explicitly acknowledge the role of WS in the onset or maintenance of BN symptoms and does not provide guidance for clinicians on how to address WS during treatment. The relationship between WS, biological pressure to regain lost weight, and the maintenance of BN symptoms suggest that current cognitive behavioral models of BN may be improved by considering the role of WS and exploring needed treatment modifications. Indeed, a reconceptualization of existing models may offer insight into potential strategies that can be used to reduce the susceptibility to treatment dropout, nonresponse, and relapse. It is therefore necessary to consider whether, and how, clinicians' consideration of WS during case conceptualization and treatment planning could serve to improve CBT outcomes. The current review explores ways in which high WS could contribute to poor CBT outcomes, provides preliminary clinical recommendations for incorporating WS into existing cognitive behavioral treatments based on extant data and clinical wisdom, and proposes suggestions for future research needed in this domain.

Abstract
While existing treatments produce remission in a relatively large percentage of individuals with binge eating disorder (BED), room for improvement remains. Interventions designed to increase emotion regulation skills and clarify one's chosen values may be well-suited to address factors known to maintain BED. The current study examined the preliminary efficacy of a group-based treatment, Acceptance-based Behavioral Therapy (ABBT), in a small open trial (n=19), as well as the relationship between changes in hypothesized mechanisms of action and outcomes. ABBT includes the behavioral components of cognitive behavioral treatment for BED and emotion-focused strategies from acceptance and commitment therapy and dialectical behavioral therapy. Results from generalized linear multilevel modeling revealed significant fixed linear effects of time on depression, quality of life, global eating pathology, and binge frequency (all ps < .05). Global eating disorder symptoms appeared to improve rapidly from pre- to mid-treatment, and continued to improve toward post-treatment and follow-up, but at a slower rate. Binge frequency decreased rapidly from pre- to mid-treatment, followed by a slight increase at post-treatment and a reduction again by follow-up. Improvements in experiential acceptance were strongly and consistently related to decreases in overall eating pathology across several measures (rs = .35-.54). Additionally, greater access to emotion regulation strategies was strongly related to decreases in overall eating pathology (r= .67). Preliminary results support the efficacy of this novel treatment approach and indicate that additional research on ABBT for BED is warranted.

Abstract
Multiple dimensions of impulsivity (e.g., affect-driven impulsivity, impulsive inhibition - both general and food-specific, and impulsive decision-making) are associated with binge eating pathology cross-sectionally, yet the literature on whether impulsivity predicts treatment outcome is limited. The present pilot study explored impulsivity-related predictors of 20-week outcome in a small open trial (n = 17) of a novel treatment for binge eating disorder. Overall, dimensions of impulsivity related to emotions (i.e., negative urgency) and food cues emerged as predictors of treatment outcomes (i.e., binge eating frequency and global eating pathology as measured by the Eating Disorders Examination), while more general measures of impulsivity were statistically unrelated to global eating pathology or binge frequency. Specifically, those with higher levels of negative urgency at baseline experienced slower and less pronounced benefit from treatment, and those with higher food-specific impulsivity had more severe global eating pathology at baseline that was consistent at post-treatment and follow-up. These preliminary findings suggest that patients high in negative urgency and with poor response inhibition to food cues may benefit from augmentation of existing treatments to achieve optimal outcomes. Future research will benefit from replication with a larger sample, parsing out the role of different dimensions of impulsivity in treatment outcome for eating disorders, and identifying how treatment can be improved to accommodate higher levels of baseline impulsivity.
