Abstract
OBJECTIVE The comorbidity of binge eating and heavy drinking (BE + HD) is concerning due to high prevalence and associated consequences. Affective pathways may maintain BE + HD, yet more micro-level research is needed. This study used ecological momentary assessment (EMA) to examine between-person and day-level relationships between positive and negative affect and binge eating or heavy drinking episodes in BE + HD. METHODS Participants (N = 53) were adults with binge-spectrum eating disorders who completed between 7 and 14 days of EMA prior to a treatment for binge eating. RESULTS Anxiety was highest on days with both binge eating and heavy drinking, while excitement and confidence were highest on days with only heavy drinking episodes for BE + HD. Global negative affect was relatively stable surrounding binge eating episodes. Guilt significantly increased prior to binge eating, and sadness significantly decreased following binge eating. Global positive affect significantly decreased prior to and stopped decreasing following heavy drinking episodes. DISCUSSION Results support binge eating being negatively reinforced by specific aspects of negative affect, while heavy drinking may be positively reinforced by global positive affect for individuals with BE + HD. Clinicians should incorporate interventions that focus on specific negative affect dimensions and that promote alternative rewarding activities besides heavy drinking.

Abstract
OBJECTIVE Anxiety sensitivity (AS), the trait-like fear of symptoms of anxiety, has been associated with eating disorder (ED) pathology broadly, bulimia nervosa (BN) symptoms specifically, and the anxiety disorders that are commonly comorbid with BN. AS, especially for physical symptoms specifically, maybe a risk and maintenance factor for BN and comorbid anxiety. METHOD Adult participants with BN (n = 44) in a clinical trial comparing CBT to mindfulness and acceptance-based treatment (MABT) reported ED symptoms, trait anxiety, and AS through treatment and follow-up. We predicted that greater early reduction (i.e., within the first month of treatment) in AS would predict greater reductions in ED symptoms and trait anxiety at post-treatment and follow-up. RESULTS Early reductions in AS for physical concerns predicted lower ED symptoms and trait anxiety at post-treatment but not follow-up. Exploratory analyses indicated that treatment groups did not differ in either early or total change in AS, controlling for baseline AS. DISCUSSION Early reductions in AS may be an important treatment target for BN, and may additionally support reductions in anxiety. Future research should identify which components of CBT and MABT best target AS, to deliver these components early in treatment, when they can have maximum effect. PUBLIC SIGNIFICANCE Anxiety sensitivity, the fear of symptoms of anxiety, is associated with eating disorders (ED). In this study, participants in treatment for bulimia nervosa reported ED symptoms, trait anxiety, and anxiety sensitivity through treatment and follow-up. Greater early reductions in anxiety sensitivity predicted lower ED symptoms and trait anxiety at post-treatment. Future research should identify which elements of treatment best target anxiety sensitivity, to deliver them early in treatment.

Abstract
Non-purging compensatory behaviors (NPCB; e.g. driven exercise, fasting, other extreme behaviors) are a subcategory of compensatory behaviors typically characterized as infrequent and less severe. Limited prior research has studied NPCB despite their increasing prevalence among adults with binge-spectrum eating disorders (B-ED). More research is needed to understand the types of NPCB present among B-ED and the association between NPCB, clinical severity, and treatment outcomes. Secondary analyses were conducted among 155 adults with B-ED in cognitive-behavioral (CBT)-based clinical trials. At baseline and post-treatment, clinical interviews of eating pathology assessed binge eating frequency, purging compensatory behavior frequency, and global eating pathology. The following NPCB were also assessed: driven exercise, 24-h fasting, 8+ waking hours of compensatory fasting, chewing and spitting, and other extreme weight control behaviors. Participants engaging in NPCB reported higher global eating pathology than those not engaging in NPCB. Frequency of chewing and spitting and 24-h fasting significantly decreased over treatment. Engagement in NPCB at baseline did not predict CBT outcomes. The current study highlights the prevalence and clinical severity of NPCB in B-ED but offers promising results regarding the potential for CBT to improve these behaviors. More research is needed on other extreme weight control behaviors reported qualitatively in our sample and on the maintenance of improvements in non-purging behaviors after CBT.

Abstract
Using data from 165 adult participants who enrolled in four studies of cognitive-behavioral therapy (CBT) for binge-spectrum eating disorders (EDs), this secondary analysis examined 1) whether pretreatment hopelessness predicted posttreatment eating pathology, loss-of-control (LOC) eating frequency, and purging frequency; 2) whether treatment had an indirect effect on those outcomes through change in hopelessness; and 3) whether treatment had an indirect effect on hopelessness through those ED measures. The Eating Disorder Examination was used to assess overall eating pathology, LOC frequency, and purging frequency. Hopelessness was measured with one item from the Beck Depression Inventory-II. Regression models showed that pretreatment hopelessness predicted posttreatment LOC eating frequency but not overall eating pathology or purging frequency. Single-group tests of indirect effects showed no effect of reduction in hopelessness on reduction in ED symptoms, but there was an effect of reduction in ED symptoms on reduction in hopelessness.

Abstract
OBJECTIVE Individuals with bulimia nervosa (BN) engage in both maladaptive (i.e., compulsive and/or compensatory) and adaptive exercise (e.g., for enjoyment). No research has examined whether those who engage in adaptive, compulsive, and/or compensatory exercise exhibit differences in BN pathology or treatment outcome compared to those not engaging in exercise, limiting intervention efficacy. METHOD We examined associations of baseline exercise engagement with baseline and posttreatment BN pathology among 106 treatment-seeking adults (Mage = 37.4, SDage = 12.95, 87.74% female, 68.87% White) enrolled across four clinical trials of outpatient enhanced cognitive behavioral therapy for BN (range: 12-16 sessions). Analysis of covariances examined associations between baseline exercise type and baseline/posttreatment global eating pathology, dietary restraint, loss-of-control (LOC) eating, and purging frequency. RESULTS Those engaging in only adaptive exercise reported lower global eating pathology compared to those engaging in compulsive-only exercise (Est = -1.493, p = .014, Mdiff = -.97) while those engaging in baseline compulsive exercise reported less LOC eating compared to those not engaging in exercise (Est = -22.42, p = .012, Mdiff = -12.50). Baseline engagement in compulsive-only exercise was associated with lower posttreatment global eating pathology compared to baseline engagement in no exercise (Est = -.856, p = .023, Mdiff = -.64) and both compulsive and compensatory exercise (Est = .895, p = .026, Mdiff = -1.08). DISCUSSION Those engaging in compulsive, compensatory, adaptive, and no exercise exhibit different patterns and severity of BN pathology. Future research is needed to position treatments to intervene on maladaptive, while still promoting adaptive, exercise. PUBLIC SIGNIFICANCE STATEMENT No research to date has examined whether those who engage in adaptive, compulsive, and/or compensatory exercise exhibit differences in BN pathology or treatment outcome compared to those not engaging in exercise, limiting targeted intervention efforts. We found that those engaging in compulsive, compensatory, and adaptive exercise exhibit different patterns of BN pathology and that adaptive exercise engagement was related to lower cognitive eating disorder symptoms at baseline.

Abstract
Binge-spectrum eating disorders (EDs; bulimia nervosa, binge eating disorder) often develop during adolescence and are associated with serious psychological and physical consequences. Current treatments for adolescents are highly behavioral in nature and while efficacious, many patients do not reach remission indicating that current treatments fail to target a key maintenance factor for EDs. One potential maintenance factor is poor family functioning (FF). In particular, high family conflict (e.g., arguing, critical comments) and low family cohesion (e.g., warmth, support) are known to maintain ED behaviors. Poor FF can (1) cause or exacerbate an adolescent's use of ED behaviors to cope with life stress and/or (2) inhibit parents from being a resource to adolescents during ED treatment. Attachment-Based Family Therapy (ABFT) is specifically designed to improve FF, and thus may be a promising adjunct to behavioral ED intervention strategies. ABFT, however, has not been tested in adolescents with binge-spectrum EDs. Thus, the current study is the first to evaluate a 16-week adapted ABFT treatment for adolescents with EDs (N = 8, Mage = 16.00, 71.43% female, 71.43% White) fusing together behavioral treatment for EDs with ABFT for highest possible impact. Eight families were treated in an open pilot trial to examine treatment feasibility, acceptability, and preliminary efficacy on FF and eating pathology. Overall, findings were promising. ABFT + B treatment was feasible and acceptable and showed preliminary evidence that it could improve FF and ED behaviors. Future research will test this intervention in a larger sample and further examine the role of FF in maintaining ED symptoms.

Abstract
OBJECTIVE To examine trajectories of therapeutic skills use and weekly relations between skills use and symptom change during the enhanced version of cognitive-behavioral therapy (CBT-E) for bulimia nervosa (BN). METHOD Fifty-five adults (M age: 39.0 ± 14.1; 83.9% female; 64.3% White, 93.6% non-Hispanic/Latino) receiving CBT-E for BN-spectrum eating disorders (EDs) self-monitored their use of five therapeutic skills (i.e., regular eating, eating enough to prevent excessive hunger and eating a range of macronutrients, breaking dietary rules, urge management strategies, and mood management strategies) several times per day during treatment. Patients also self-reported their ED symptoms (i.e., frequency of binge eating, compensatory behaviors, and dietary restraint) weekly. We examined trajectories of use of each CBT-E skill and temporal relations between skills use and ED symptoms from week-to-week during treatment. RESULTS Participants showed significant increases in eating enough to prevent excessive hunger and eating a range of macronutrients from week-to-week (p < .05). Regular eating, eating enough to prevent excessive hunger, and eating a range of macronutrients 1 week predicted lower binge eating and compensatory behaviors the same week and the following week, and urge management strategy use predicted greater binge eating the same week and the following week (p < .05). CONCLUSIONS Results showed temporal relationships between therapeutic skills use and symptom change on a weekly level, with evidence that using skills targeting dietary restraint was associated with lower BN symptoms. Findings highlight the promise of future work to elucidate the most potent CBT-E skills for symptom improvement and inform more targeted interventions. PUBLIC SIGNIFICANCE Findings showed weekly relationships between therapeutic skills use and symptom change during treatment, with evidence that using CBT-E skills aimed to reduce dietary restraint (i.e., regular eating, eating enough to prevent excessive hunger, and eating a range of macronutrients) was associated with lower BN symptoms. Future work has the potential to identify the most potent CBT-E skills for symptom improvement and inform more targeted interventions.

Abstract
OBJECTIVE Maladaptive exercise (i.e., driven and/or compensatory exercise) is common in binge-spectrum eating disorders (EDs; e.g., bulimia nervosa, binge ED) and associated with adverse treatment outcomes. Alternatively, individuals with EDs are often also engaging in adaptive exercise (e.g., for enjoyment or health improvement), and increasing adaptive exercise may decrease ED symptoms. The current study aimed to understand which exercise episodes are likely to be maladaptive/adaptive so that interventions can appropriately decrease/increase maladaptive and adaptive exercise. METHOD We used latent profile analysis (LPA) to identify pre-exercise affective profiles of 661 exercise episodes among 84 individuals with binge-spectrum EDs and examined associations between LPA-identified profiles and subsequent exercise motivations using ecological momentary assessment. RESULTS A two-profile solution best fit our data: Profile 1 (n = 174), 'positive affectivity,' and Profile 2 (n = 487), 'negative affectivity.' Episodes in the 'negative affectivity' profile were more likely to be endorsed as both driven and intended to influence body shape/weight. Episodes in the 'positive affectivity' profile were more likely to be endorsed as exercising for enjoyment. CONCLUSIONS Results support two phenotypes of exercise episodes, and differential associations of these phenotypes with adaptive and maladaptive motivations for exercise.

Abstract
OBJECTIVE Emotion dysregulation (i.e., a multi-component term comprising nonacceptance of emotional responses, difficulty engaging in goal-directed behaviour, impulse control difficulties, lack of emotional awareness, limited access to emotion regulation strategies, and lack of emotional clarity) is a well-established transdiagnostic risk and maintenance factor for eating disorders. To date, there is limited information on how varying scores on subdomains of emotion dysregulation may yield distinct profiles in individuals with binge-spectrum eating disorders (B-EDs), and how these emotion dysregulation profiles may inform resultant symptomatology. METHOD In the current study, treatment-seeking individuals with B-EDs (n = 315) completed the Difficulties in Emotion Regulation Scale (DERS) and Eating Disorder Examination. Latent profile analysis was conducted on the six subscales of the DERS. Identified latent profiles were examined as predictors of eating disorder pathology using linear regression, and a two-class model of emotion dysregulation fit the data. RESULTS Class 1 (n = 113) was low in all of the DERS subscales, while Class 2 (n = 202) was high in all of the DERS subscales. Individuals in Class 2 had a significantly higher frequency of compensatory behaviours in the past month (F(1,313) = 12.97, p < 0.001), and significantly higher restraint scores (F(1,313) = 17.86, p < 0.001). The classes also significantly differed in terms of eating concern (F(1,313) = 20.89, p < 0.001) and shape concern (F(1,313) = 4.59, p = 0.03), with both being higher for Class 2. DISCUSSION We found only two distinct classes of emotion dysregulation in B-ED's such that individuals were simply high or low in emotion dysregulation. These results suggest that it may be more valuable for future research to evaluate emotion dysregulation as a cohesive whole rather than conceptualising the construct as having truly distinct subdomains.

Abstract
Inhibitory control, one's ability to inhibit automatic responses to desirable stimuli, may be inadequately targeted in interventions for loss-of-control eating (LOC). Promising evidence has identified inhibitory control trainings (ICTs) as an avenue to target inhibitory control directly; however, effects of ICTs on real-world behavior are limited. Compared to typical computerized trainings, virtual reality (VR) presents several potential advantages that may address key shortcomings of traditional ICTs, i.e. poor approximation to everyday life. The present study utilized a 2 × 2 factorial design of treatment type (ICT vs sham) by treatment modality (VR vs standard computer), which allows for increased statistical power by collapsing across conditions. Our primary aim was to examine the feasibility and acceptability of six weeks of daily training among groups. A secondary aim was to preliminarily assess main and interactive effects of treatment type and modality on target engagement and efficacy (i.e., training compliance, change in LOC episodes, inhibitory control, and implicit liking of foods). Participants (N = 35) with ≥1×/weekly LOC were assigned to one of four conditions and completed ICTs daily for six weeks. The trainings were feasible and acceptable, evinced by high retention and compliance across time and condition. Although completing daily trainings across treatment types and modalities was associated with large decreases in LOC, there were no meaningful effects of either treatment type or modality, nor a significant interaction effect, on LOC or mechanistic variables. Future research should aim to increase the efficacy of ICT (both standard and VR-based) and test in fully-powered clinical trials.

Abstract
OBJECTIVE This study aimed to: 1) compare rates of dietary restraint and restriction between adolescents with and without loss-of-control (LOC) eating who were seeking weight control and 2) examine temporal relations between restraint/restriction and LOC eating. METHOD 37 adolescents seeking weight control (mean age: 15.4 ± 1.5; 62 % White; 57 % female; mean BMI percentile = 97.3 ± 3.1) completed a one-week ecological momentary assessment protocol and reported on dietary restraint/restriction and eating behavior prior to beginning a weight control intervention. Chi-square tests examined differences in frequency of restraint/restriction between participants with and without LOC eating. Multilevel models examined associations between dietary restraint/restriction and LOC eating at the next survey and on the next day. RESULTS Of 37 participants, 15 (41 %) reported engaging in LOC eating. Participants with LOC eating more frequently endorsed several forms of restraint and restriction versus participants without LOC eating. Attempting to avoid enjoyable foods and attempting to limit eating at one survey predicted greater likelihood of LOC eating at the next survey. CONCLUSIONS Findings suggest that attempted restraint, but not actual restriction, was associated with LOC eating. Research should explore additional factors that may influence these relationships, which could inform weight control treatments that address restraint/restriction.

Abstract
OBJECTIVE Individuals with eating disorders (EDs) often engage in maladaptive exercise (e.g., feeling driven, or to "compensate" for eating) which maintains eating pathology. Maladaptive exercise has been theorized to help individuals with EDs regulate emotions by enhancing positive affect (PA) and reducing negative affect (NA) associated with binge episodes and poor body image. However, no research has considered the presence of non-maladaptive exercise or evaluated this theory in binge-spectrum EDs. METHODS This study evaluated affective trajectories pre- and post-exercise and examined exercise type (maladaptive or non-maladaptive) as a moderator. We recruited adults with binge-spectrum EDs (N = 107; n = 84 endorsed exercise) to complete a 7- to 14-day ecological momentary assessment protocol assessing NA (anxiety, guilt, and sadness), PA (excitement and cheerfulness), and exercise. RESULTS There was a significant quadratic trajectory of PA pre-exercise, suggesting that the upward trajectory of PA leveled out as it moved closer to an exercise episode. Exercise type significantly moderated the cubic trajectory of PA post-exercise, such that the upward trajectory of PA accelerated in the hours following non-maladaptive exercise episodes while the downward trajectory of PA accelerated in the hours following maladaptive exercise episodes. No trajectories of NA demonstrated significant effects. CONCLUSIONS Pre-exercise trajectories of PA may reflect positive expectancies around exercise. Post-exercise trajectories of PA suggest that non-maladaptive exercise promotes increased PA. Future research should evaluate when, and for whom, exercise serves to regulate affect and examine other momentary risk factors of exercise in EDs. PUBLIC SIGNIFICANCE Individuals with EDs often engage in maladaptive exercise (e.g., feeling driven, or to "compensate" for eating). Maladaptive exercise has been theorized to help individuals with EDs regulate emotions. This study evaluated affective trajectories pre- and post-exercise and examined whether exercise type (maladaptive or non-maladaptive) changed these trajectories. Pre-exercise trajectories of PA may reflect positive expectancies around exercise. Post-exercise trajectories of PA suggest that non-maladaptive exercise promotes increased PA.

Abstract
Cognitive Behavior Therapy (CBT) for bulimia nervosa (BN) requires patient skill utilization (use of treatment skills) and skill acquisition (successful skill use) for symptom improvement. Treatment outcomes are unsatisfactory, possibly due to poor skill acquisition and utilization by post-treatment. Just-in-time adaptive interventions (JITAIs), momentary interventions delivered at opportunities for skill practice, may improve skill acquisition and utilization. Participants (N = 56 individuals with bulimia-spectrum eating disorders) completed electronic self-monitoring in CBT+ and received JITAIs or no JITAIs alongside 16 sessions of CBT. Feasibility, acceptability, target engagement, and treatment outcomes were evaluated. JITAIs demonstrated feasibility and acceptability. Treatment outcomes and target engagement did not differ between conditions. The lack of group differences in target engagement and treatment outcomes may be explained by skill use self-monitoring promoting skill utilization and acquisition or low statistical power. Our findings suggest that JITAIs are feasible and acceptable during CBT for BN and warrant additional study.

Abstract
OBJECTIVE Despite evidence supporting the link between dietary restraint (i.e., attempts at dietary restriction) and loss of control (LOC) eating among individuals with binge-spectrum eating disorders (EDs), some research suggests that dietary restraint may not be linked to LOC eating in all contexts. It is currently unknown how often dietary restraint results in successful dietary restriction, or which types of restraint/restriction confer highest risk for LOC eating. Furthermore, little research has evaluated momentary, temporal associations between dietary restraint and LOC eating. Thus, the present study aimed to (1) characterize dietary restraint and restriction, among individuals with LOC eating, and (2) examine temporal relationships between restraint/restriction and LOC eating within- and between-subjects. METHOD The current study recruited adults with binge spectrum EDs (n = 96, 80.4% female) to complete a 7-14-day ecological momentary assessment protocol assessing ED symptoms. Multilevel models and linear regression evaluated within- and between-subjects associations between momentary restraint/restriction and LOC eating, respectively. RESULTS Attempted avoidance of enjoyable foods, limiting the amount eaten, and any restraint predicted greater likelihood of LOC eating at the next survey. Attempts to delay eating predicted reduced likelihood of LOC eating at the next survey, though this effect was no longer statistically significant after correcting for multiple comparisons. Diagnostic presentation moderated the association between attempted avoidance of enjoyable foods and LOC eating such that this association was significantly stronger for those on the BN-spectrum. DISCUSSION Dietary restraint seems to be more predictive of LOC eating than dietary restriction both within- and between-subjects. Future treatments should target dietary restraint to reduce LOC eating. PUBLIC SIGNIFICANCE Some research suggests that dietary restriction (i.e., reduced calorie intake) and restraint (i.e., attempted restriction) may not be linked to LOC eating in all contexts. We found that dietary restraint is more predictive of LOC eating than dietary restriction both within and between individuals. Future treatments should target dietary restraint to reduce LOC eating.

Abstract
PURPOSE Difficulty reappraising drives to consume palatable foods may promote poorer inhibition and binge eating (BE) in adults with obesity, but neural underpinnings of food-related reappraisal are underexamined. METHODS To examine neural correlates of food-related reappraisal, adults with obesity with and without BE wore a portable neuroimaging tool, functional near-infrared spectroscopy (fNIRS). fNIRS measured activity in the prefrontal cortex while participants watched videos of food and attempt to "resist" the food stimuli (i.e., "consider the negative consequences of eating the food"). RESULTS Participants (N = 32, 62.5% female; BMI 38.6 [Formula: see text] 7.1; 43.5 [Formula: see text] 13.4 y) had a BMI > 30 kg/m2. Eighteen adults (67.0% female; BMI 38.2 [Formula: see text] 7.6) reported BE (≥ 12 BE-episodes in preceding 3 months). The control group comprised 14 adults who denied BE (64.0% female; BMI 39.2 [Formula: see text] 6.6). Among the entire sample, mixed models showed significant, small hyperactivation during crave and resist compared to watch (relax) condition bilaterally in the medial superior frontal gyrus, dorsolateral areas, and middle frontal gyrus (optodes 5, 7, 9, 10, 11, and 12) in the total sample. No statistically significant differences in neural activation were observed between the BE and control group. Moreover, there were no significant group by condition interactions on neural activation. CONCLUSION Among adults with obesity, BE status was not linked to differential activation in inhibitory prefrontal cortex areas during a food-related reappraisal task. Future research is needed with larger samples, adults without obesity, and inhibition paradigms with both behavioral and cognitive components. LEVEL OF EVIDENCE Level III: Evidence obtained from well-designed cohort or case-control analytic studies. TRIAL REGISTRATION # NCT03113669, date April 13, 2017.

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.

Abstract
OBJECTIVE Adjunctive mobile health (mHealth) technologies offer promise for improving treatment response to enhanced cognitive-behavior therapy (CBT-E) among individuals with binge-spectrum eating disorders, but research on the key "active" components of these technologies has been very limited. The present study will use a full factorial design to (1) evaluate the optimal combination of complexity of two commonly used mHealth components (i.e., self-monitoring and microinterventions) alongside CBT-E and (2) test whether the optimal complexity level of these interventions is moderated by baseline self-regulation. Secondary aims of the present study include evaluating target engagement associated with each level of these intervention components and quantifying the component interaction effects (i.e., partially additive, fully additive, or synergistic effects). METHOD Two hundred and sixty-four participants with binge-spectrum eating disorders will be randomized to six treatment conditions determined by the combination of self-monitoring condition (i.e., standard self-monitoring or skills monitoring) and microinterventions condition (i.e., no microinterventions, automated microinterventions, or just-in-time adaptive interventions) as an augmentation to 16 sessions of CBT-E. Treatment outcomes will be measured using the Eating Disorder Examination and compared by treatment condition using multilevel models. RESULTS Results will clarify the "active" components in mHealth interventions for binge eating. DISCUSSION The present study will provide critical insight into the efficacy of commonly used digital intervention components (i.e., skills monitoring and microinterventions) alongside CBT-E. Furthermore, results of this study may inform personalization of digital intervention intensity based on patient profiles of self-regulation. PUBLIC SIGNIFICANCE This study will examine the relative effectiveness of commonly used components of application-based interventions as an augmentation to cognitive-behavioral therapy for binge eating. Findings from this study will inform the development of an optimized digital intervention for individuals with binge eating.

Abstract
Over 70% of men are overweight, and most desire weight loss; however, men are profoundly underrepresented in weight loss programs. Gamification represents a novel approach to engaging men and may enhance efficacy through two means: (1) game-based elements (e.g., streaks, badges, team-based competition) to motivate weight control behaviors and (2) arcade-style "neurotraining" to enhance neurocognitive capacities to resist the temptation of unhealthy foods and more automatically select healthy foods. This study will use a 2 × 2 factorial design to examine the independent and combinatory efficacy of gamification and inhibitory control training (ICT). Men with overweight/obesity (N = 228) will receive a 12-month mobile weight loss program that incorporates behavioral weight loss strategies (e.g., self-monitoring, goal setting, stimulus control). Men will be randomly assigned to a non-gamified or gamified version, and an active or sham ICT. A game design company will create the program, with input from a male advisory panel. Aims of the project are to test whether a gamified (versus non-gamified) weight loss program and/or ICT (versus sham) promotes greater improvements in weight, diet, and physical activity; whether these treatment factors have combinatory or synergistic effects; to test whether postulated mechanisms of action (increased engagement, for gamification, and inhibitory control, for ICT) mediate treatment effects; and whether baseline gameplay frequency and implicit preferences for ICT-targeted foods moderate effects. It is hoped this study will contribute to improved mHealth programs for men and enhance our understanding of the impact of gamified elements and neurocognitive training on weight control.

Abstract
BACKGROUND Dietary restraint is a key factor for maintaining engagement in binge eating among individuals with binge eating disorder (BED) and bulimia nervosa (BN). Reducing dietary restraint is a mechanism of change in cognitive behavioral therapy (CBT) for individuals with BN and BED. However, many individuals who undergo CBT fail to adequately reduce dietary restraint during treatment, perhaps owing to difficulty in using treatment skills (eg, regular eating) to reduce dietary restraint during their daily lives. The SenseSupport system, a novel just-in-time, adaptive intervention (JITAI) system that uses continuous glucose monitoring to detect periods of dietary restraint, may improve CBT to reduce dietary restraint during treatment by providing real-time interventions. OBJECTIVE This study aimed to describe the feasibility, acceptability, and initial evaluation of SenseSupport. We presented feasibility, acceptability, target engagement, and initial treatment outcome data from a small trial using an ABAB (A=continuous glucose monitoring data sharing and JITAIs-Off, B=continuous glucose monitoring data sharing and JITAIs-On) design (in which JITAIs were turned on for 2 weeks and then turned off for 2 weeks throughout the treatment). METHODS Participants (N=30) were individuals with BED or BN engaging in ≥3 episodes of ≥5 hours without eating per week at baseline. Participants received 12 sessions of CBT and wore continuous glucose monitors to detect eating behaviors and inform the delivery of JITAIs. Participants completed 4 assessments and reported eating disorder behaviors, dietary restraint, and barriers to app use weekly throughout treatment. RESULTS Retention was high (25/30, 83% after treatment). However, the rates of continuous glucose monitoring data collection were low (67.4% of expected glucose data were collected), and therapists and participants reported frequent app-related issues. Participants reported that the SenseSupport system was comfortable, minimally disruptive, and easy to use. The only form of dietary restraint that decreased significantly more rapidly during JITAIs-On periods relative to JITAIs-Off periods was the desire for an empty stomach (t43=1.69; P=.049; Cohen d=0.25). There was also a trend toward greater decrease in overall restraint during JITAs-On periods compared with JITAIs-Off periods, but these results were not statistically significant (t43=1.60; P=.06; Cohen d=0.24). There was no significant difference in change in the frequency of binge eating during JITAIs-On periods compared with JITAIs-Off periods (P=.23). Participants demonstrated clinically significant, large decreases in binge eating (t24=10.36; P<.001; Cohen d=2.07), compensatory behaviors (t24=3.40; P=.001; Cohen d=0.68), and global eating pathology (t24=6.25; P<.001; Cohen d=1.25) from pre- to posttreatment. CONCLUSIONS This study describes the successful development and implementation of the first intervention system combining passive continuous glucose monitors and JITAIs to augment CBT for binge-spectrum eating disorders. Despite the lower-than-anticipated collection of glucose data, the high acceptability and promising treatment outcomes suggest that the SenseSupport system warrants additional investigation via future, fully powered clinical trials.

Abstract
OBJECTIVES Elevated glucose variability may be one mechanism that increases risk for significant psychological and physiological health conditions among individuals with binge-spectrum eating disorders (B-EDs), given the impact of eating disorder (ED) behaviors on blood glucose levels. This study aimed to characterize glucose variability among individuals with B-EDs compared with age-matched, sex-matched, and body mass index-matched controls, and investigate the association between frequency of ED behaviors and glucose variability. METHODS Participants were 52 individuals with B-EDs and 22 controls who wore continuous glucose monitors to measure blood glucose levels and completed ecological momentary assessment surveys to measure ED behaviors for 1 week. Independent samples t-tests compared individuals with B-EDs and controls and multiple linear regression models examined the association between ED behaviors and glucose variability. RESULTS Individuals with B-EDs demonstrated numerically higher glucose variability than controls (t = 1.42, p = .08, d = 0.43), although this difference was not statistically significant. When controlling for covariates, frequency of ED behaviors was significantly, positively associated with glucose variability (t = 3.17, p = .003) with medium effect size (f2 = 0.25). Post hoc analyses indicated that binge eating frequency was significantly associated with glucose variability, while episodes of 5+ hours without eating were not. DISCUSSION Glucose variability among individuals with B-EDs appears to be positively associated with engagement in ED behaviors, particularly binge eating. Glucose variability may be an important mechanism by which adverse health outcomes occur at elevated rates in B-EDs and warrants future study. PUBLIC SIGNIFICANCE This study suggests that some individuals with binge ED and bulimia nervosa may experience elevated glucose variability, a physiological symptom that is linked to a number of adverse health consequences. The degree of elevation in glucose variability is positive associated with frequency of eating disorder behaviors, especially binge eating.

Abstract
INTRODUCTION Specific characteristics of sleep (e.g., duration, quality, and fatigue) are positively associated with (ED) behaviors, specifically binge eating (BE) potentially through decreased self-regulation and increased appetite. However, prior work has been largely cross-sectional and has not examined temporal relationships between sleep characteristics and next-day ED behaviors. Thus, the present study examined daily relationships between sleep and ED behaviors among individuals with binge-spectrum EDs. METHOD Participants (N = 96) completed 7 daily ecological momentary assessment (EMA) surveys over 7-14 days; morning surveys assessed sleep characteristics and 6 randomly timed surveys each day captured ED behaviors. Analyses examined within-subject and between-subject effects of sleep quality, duration, and fatigue on BE, compensatory purging behaviors, and maladaptive exercise. RESULTS Within-subject sleep quality was significantly negatively associated with engagement in maladaptive exercise later that day. Additionally, between-subject sleep duration was significantly negatively associated with engagement in compensatory purging behaviors. DISCUSSION Within- and between-subjects associations between sleep quality and duration and compensatory behavior engagement indicate that sleep plays an important role in ED behaviors. Future research should incorporate sensor-based measurement of sleep and examine how specific facets of sleep impact BE and treatment response. LEVEL OF EVIDENCE Level II: Evidence obtained from controlled trial without randomization.

Abstract
Anhedonia is theorized as being relevant to binge eating spectrum disorders (BESDs) by palatable foods substituting the pleasure typically obtained from day-to-day activities. The current study examined whether anhedonia is associated with eating pathology at baseline and whether it predicts cognitive behavioral therapy (CBT) outcomes alone and when controlling for non-anhedonia depression symptoms. Ninety-three individuals from two randomized controlled trials completed the Eating Disorder Examination and Beck Depression Inventory-II at pre-, mid-, and post-treatment. Results showed that anhedonia was positively associated with global eating pathology at baseline, and larger pre- to mid-treatment anhedonia and non-anhedonia reductions predicted larger pre- to post-treatment global eating pathology reductions, though the anhedonia association was no longer significant when controlling for non-anhedonia depression. Anhedonia appears to be related to global eating pathology in CBT for BESDs, but not loss of control eating. Further research is needed to elucidate the relationship between anhedonia and BESDs.

Abstract
OBJECTIVE Loss-of-control (LOC) eating is associated with eating disorders and obesity, and thus it is imperative to understand its momentary risk factors in order to improve intervention efforts. Negative affect has been proposed as a momentary risk factor for LOC eating, but the evidence for its effects in children and adolescents is mixed. Short sleep duration (which is very common in youth), may be one variable that moderates the relation between negative affect and subsequent LOC eating. As such, we aimed to examine the moderating role of within-person sleep duration on the momentary relations between negative affect and subsequent LOC eating. METHOD We recruited children (N = 30) with overweight/obesity ages 8-14, who completed a 2-week ecological momentary assessment protocol assessing negative affect and LOC eating several times per day, while also wearing a sleep actigraphy device and completing sleep diaries. RESULTS Consistent with hypotheses, within-person sleep duration moderated the next-day momentary relation between within-person negative affect and LOC eating, such that shorter sleep duration strengthened the positive relation between negative affect and loss-of-control eating. CONCLUSIONS Results suggest that, in children and adolescents, fluctuations in sleep duration may influence susceptibility to losing control over eating after experiencing negative affect. Future research should further investigate other metrics of sleep disturbance as they relate to emotion regulation and LOC eating. Such research will set the stage for augmenting paediatric interventions to better target maintenance factors for LOC eating.

Abstract
Behavioral treatments for psychological disorders characterized by reward-driven maladaptive behaviors (e.g., substance use disorder, eating disorders, behavioral addictions) primarily seek to reduce hyper-reward response to disorder-specific stimuli. Suboptimal outcomes for these treatments highlight the need to also target hypo-reward response to day-to-day life activities. The present study sought to conduct an initial test of a novel behavioral treatment, Reward Re-Training (RRT) to target hyper- and hypo-reward response in individuals with binge eating. Individuals with binge eating (N = 23) were randomly assigned to either 10 weeks of outpatient, group-based RRT treatment or a waitlist control. RRT was found to be feasible and acceptable, demonstrated large impacts on both hypo- and hyper-reward response (measured by self-report (pre-to post-treatment ηp2 range 0.38-0.58) and neural activation via fMRI), and was efficacious in reducing eating disorder pathology (ηp2 range 0.40-0.64, including binge eating, ηp2 = 0.64) compared to waitlist control (ηp2 range 0.00-0.04). This pilot data provides preliminary support for the feasibility, acceptability, and effectiveness of a novel treatment targeting reward imbalance for individuals with binge eating. Future evaluations of RRT may benefit from an active treatment comparison condition and a follow-up assessment to examine persistence of positive outcomes.

Abstract
PURPOSE Maladaptive exercise is common among individuals with binge-spectrum eating disorders. One mechanism that may drive engagement in exercise in this population is state body dissatisfaction. However, no studies to date have examined prospective, momentary relationships between state body dissatisfaction and exercise. METHODS Adults with binge-spectrum eating disorders (N = 58) completed a 7-14-day ecological momentary assessment protocol assessing exercise and state body dissatisfaction several times per day. Multilevel models were used to evaluate prospective reciprocal associations between state body dissatisfaction and exercise. Mixed models examined trajectories of change in state body dissatisfaction pre- and post-exercise. Additional models examined exercise type (maladaptive vs. adaptive) as a moderator. RESULTS Momentary increases (i.e., greater than one's average levels) in state body dissatisfaction at any given timepoint did not prospectively predict engagement in exercise at the next nearest timepoint. Exercise at any given timepoint did not prospectively predict momentary increases in state body dissatisfaction. State body dissatisfaction was found to increase in the initial hours preceding an exercise episode (linear estimate, β = - 0.012, p = 0.004). State body dissatisfaction did not significantly change in the hours following engagement in exercise. Exercise type did not moderate these associations. CONCLUSION If replicated, our results may suggest that momentary increases in state body dissatisfaction may not be associated with exercise behaviors in individuals with binge-spectrum eating disorders. LEVEL OF EVIDENCE Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, orreports of expert committees.

Abstract
PURPOSE Maladaptive exercise (i.e., exercise that is either driven or compensatory) is thought to momentarily down-regulate elevated fear of weight gain (FOWG). However, little research has examined associations between FOWG and exercise, and no research has measured FOWG at a momentary level or considered exercise type (i.e., maladaptive vs. adaptive). Thus, we examined both within- and between-subject associations between FOWG and exercise among individuals with trans-diagnostic binge eating. METHODS We recruited treatment-seeking adults (N = 58, 82.9% female) to complete a 7-14-day ecological momentary assessment protocol which assessed levels of FOWG and exercise engagement and type. Mixed models and generalized estimating equations assessed within-subject associations, and linear regression assessed between-subject associations. RESULTS There was no main effect of FOWG on exercise engagement at the next survey. However, unexpectedly, exercise type moderated this relationship such that the relationship between FOWG and exercise was strongest for episodes of adaptive exercise. Overall exercise frequency accounted for 10.4% of the variance in FOWG and exercise type explained an additional 1.7% of the variance in FOWG. CONCLUSION The findings of the current study indicate that momentary levels of FOWG are associated with subsequent adaptive exercise episodes, while higher overall levels of maladaptive exercise were associated with higher levels of FOWG. Future treatments should place a greater emphasis on reducing the frequency of maladaptive exercise by providing strategies for reducing FOWG. LEVEL OF EVIDENCE Level IV: Evidence obtained from multiple time series analysis such as case studies.

Abstract
PURPOSE Loss of control eating (LOCE) is supported as a maladaptive regulation strategy for high negative affect (NA) and low positive affect (PA). Yet, little is known about the day-to-day activities outside of eating that may precipitate such changes in affect and impact risk for LOCE. The current ecological momentary assessment study sought to examine whether (1) low NA and high PA at a given survey would prospectively predict lower likelihood of a LOCE episode at the next survey, and (2) having recently engaged in various non-eating activities would be associated with changes in average NA and PA levels at the same survey. METHODS Data collected from 66 participants with LOCE over 7-14 days were analyzed using generalized estimating equations. RESULTS High NA but not low PA at a given survey prospectively predicted lower likelihood of a LOCE episode at the next survey. Having recently engaged in outdoor recreation and socializing was associated with lower than one's usual NA and higher than one's usual PA at the same survey, social media was associated with higher than one's usual NA and lower than one's usual PA, self-care was associated with higher than one's usual PA, and napping was associated with lower than one's usual PA. CONCLUSION Individuals may benefit from increasing the frequency of daily non-eating activities that reduce NA, since it appears to be a more salient predictor of LOCE than PA. Further research is needed to elucidate this LOCE maintenance model, particularly in regard to the role of PA. LEVEL OF EVIDENCE Level IV, multiple time series without intervention.

Abstract
OBJECTIVE Prior work evaluating cognitive flexibility (i.e., the ability to alter behavior in response to environmental changes) in bulimia-spectrum eating disorders (BN-ED) has produced mixed findings, perhaps due to reliance on set-shifting paradigms that do not effectively isolate cognitive flexibility. Task-switching paradigms are more precise, but no study has examined task-switching in BN-ED. Further, no study has examined whether cognitive flexibility deficits in BN-ED are disorder-specific (e.g., confined to food-related responses). Thus, the present study re-evaluated cognitive flexibility in BN-ED using general and food-specific task-switching paradigms. METHOD Individuals with BN-ED (n = 28) and healthy controls (HC; n = 39) completed a cued color-shape switching task (CCSST) and a novel food-specific variation (FCCSST). We compared BN-ED and HC on switch costs (reflective of transient task-switching) and mix costs (reflective of maintenance of switching behavior). RESULTS Switch and mix costs were not significantly different between BN-ED and HC in terms of either accuracy or reaction time on the CCSST or FCCSST. CONCLUSIONS Findings suggest neither general nor food-specific cognitive flexibility is impaired in BN-ED. Rigidity in BN-ED (e.g., continued engagement in compensatory behaviors despite psychoeducation that these behaviors are ineffective for weight loss) may be a result of other neurocognitive impairments rather than cognitive flexibility deficits.

Abstract
OBJECTIVE Emotion regulation (ER) deficits are associated with illness severity in individuals with bulimia nervosa. We examined whether baseline ER abilities are associated with remission following enhanced cognitive behavioural therapy for eating disorders (CBT-E). METHOD Participants (N = 50, 85.0% female) receiving CBT-E completed a measure (yielding a global score and six subscale scores) of ER pre-treatment. Remission was assessed by the Eating Disorder Examination at post-treatment and follow-up. Analyses tested associations between baseline ER and behavioural, cognitive, or full remission at post-treatment and three-month follow-up. RESULTS Lower global ER abilities, measured by the Difficulties in Emotion Regulation Scale, were associated with lower likelihood of behavioural and full, but not cognitive, remission at post-treatment. Specifically, individuals low in emotional clarity and impulse control were less likely to be behaviourally remitted. Those low in emotional acceptance, awareness, clarity, or strategies to manage emotion were less likely to be fully remitted. Global ER scores were not associated with any remission type at follow-up. DISCUSSION Baseline ER deficits were associated with lower likelihood of behavioural or full remission at post-treatment. However, ER was less associated with remission at follow-up, indicating that ER is most important during treatment. Findings highlight a need for targeted treatments aimed at improving ER.

Abstract
OBJECTIVE Fear of weight gain (FOWG) is increasingly implicated in the maintenance of binge-spectrum eating disorders (EDs; e.g., bulimia nervosa [BN], binge-eating disorder [BED]) through the pathway of increased dietary restriction. However, particularly in binge-spectrum EDs, research is nascent and based on retrospective self-report. To improve treatment outcomes, it is critical to better understand the momentary relations between FOWG and dietary restriction. METHOD Sixty-seven adults with binge spectrum EDs completed a 7-14-day ecological momentary assessment protocol that included items regarding FOWG, ED behaviors, and types of dietary restriction (e.g., attempted restraint vs. actual restriction) several times per day. Multilevel models were used to evaluate reciprocal associations between FOWG and dietary restriction, and to evaluate the indirect of effects of dietary restriction on the relation between FOWG and binge eating. RESULTS While main effects were not statistically significant, ED presentation significantly moderated the association between increases in FOWG at time1 and both attempted and actual avoidance of enjoyable foods at time2 such that those with BN-spectrum EDs were more likely to avoid enjoyable foods following increased FOWG compared to those with BED-spectrum EDs. Engagement in restriction at time1 was not associated with decreased FOWG at time2. DISCUSSION Prospective associations between FOWG and restriction suggest that individuals with BN may be more likely to restrict their eating following increased FOWG. These findings suggest FOWG may be an important target for future treatments.

Abstract
OBJECTIVE The Food Craving Acceptance and Action Questionnaire (FAAQ) was developed to measure psychological flexibility around food-related internal experiences (e.g., thoughts, feelings, urges) and has two subscales, acceptance and willingness. However, the FAAQ factor structure has not yet been systematically validated with a clinically relevant sample. METHODS Two weight-loss treatment seeking samples (total N = 462; 80.4% female) ages 18 to 70 (M = 52.6, SD = 9.8) completed the FAAQ before and after group-based treatment of overweight or obesity. RESULTS Confirmatory factor analysis on the FAAQ's previously observed two-factor model produced poor model fit. An alternative 7-item model removing specific items that contributed to poor fit and were conceptually relevant to remove provided good model fit. The resulting revised 7-item FAAQ (items 1,3,6 removed) had adequate internal consistency and significant predictive validity for the Total score and subscales, and showed initial construct validity for the Total score. CONCLUSIONS Results from this study suggest researchers and clinicians should now use the 7-item FAAQ-II, which retains the Willingness and Acceptance subscales. Future research is needed with other relevant samples to confirm the FAAQ-II's factor structure and psychometric properties.

Abstract
OBJECTIVE Binge planning (BP; i.e., preparatory thoughts and actions to facilitate future binge-eating episodes) is hypothesized to distract individuals from negative affect and increase the salience of food. Thus, individuals who engage in BP may report greater positive eating expectancies (i.e., beliefs about the outcomes of eating) and hedonic hunger (i.e., desire to eat for pleasure), as BP may increase the likelihood of obtaining these expected outcomes; but empirical tests of this possibility are needed. METHOD Prior to starting treatment, adults (N = 86) with bulimia-spectrum eating disorders were assessed for engagement in BP and self-reported on eating expectancies and hedonic hunger. RESULTS Twenty-nine participants (33.7%) reported planning at least one binge-eating episode in the previous 28 days. Compared to individuals who did not report BP, individuals who reported BP had greater expectancies that eating would alleviate negative affect (t = -2.54, p = .013) and boredom (U = 503.50, p = .006). Groups did not differ on levels of hedonic hunger (t = -1.68, p = .096). DISCUSSION These findings suggest that BP status is linked to expectancies that eating will reduce negative affect. However, more data are needed to determine the temporal relationships among eating expectancies, hedonic hunger and BP. TRIAL REGISTRATION NUMBERS NCT02716831, NCT03673540.

Abstract
Emotional eating (EE) has been proposed as a key weight loss barrier. However, most investigations of EE rely on retrospective self-reports, which may have poor construct validity. This study evaluated concordance between a common self-report EE measure and a novel method for assessing momentary EE using ecological momentary assessment (EMA). We further assessed the utility of both measures for predicting both BMI and weight outcomes. Participants with overweight or obesity enrolled in a weight loss trial (N = 163) completed a self-report measure of EE and underwent an EMA protocol that assessed momentary emotions and eating behaviors. Momentary EE was derived from EMA data using generalized linear mixed-effects models. Linear regression models examined associations between both EE measures and concurrent BMI as well as weight losses over 30 months. Retrospectively self-reported EE and momentary EE were negatively correlated with one another (r = -0.27). Higher momentary EE and higher retrospectively reported EE both predicted higher concurrent BMI, and higher retrospectively reported EE predicted poorer weight loss outcomes at all time points (p < 0.05). By contrast, higher momentary EE predicted improved weight outcomes at 1-year and 2-year follow-up (p < 0.05). Our findings extend prior research suggesting that retrospective self-report EE measures capture a different construct than intended and suggest that momentary EE could predict improved weight loss outcomes.

Abstract
Although 40-60% of individuals with eating disorders (EDs) report engaging in maladaptive exercise, self-reported reasons for engaging in exercise vary. Further, no studies have examined momentary reasons for exercise and whether reasons for exercising could be both adaptive and maladaptive for any episode. Examining reasons for exercise can inform interventions which more effectively target maladaptive exercise. The current study recruited adults with binge-spectrum EDs (N = 58, 89.2% Female) and assessed self-reported reasons for exercise using ecological momentary assessment over 7-14 days. Exercise episodes were categorized as maladaptive if the participant endorsed exercising to compensate for eating or feeling driven to exercise. On average, participants reported exercising 8 times (SD = 8) over the 7-14 days. On average, 73% of exercise episodes were maladaptive. Participants most frequently stated exercising to control shape or weight (67.2% of episodes), feeling driven (62.9%), and exercising as part of a routine (52.9%). Participants least endorsed exercising so that they could eat more later (9.8%). Participants reported a mean of 3.6 reasons for exercising at each episode (SD = 1.85, mode = 1.0). As hypothesized, individuals with EDs were exercising for several reasons at each exercise episode. Further, the extent to which each exercise episode is maladaptive varied between participants and even within a single participant's exercise episodes. These findings underscore the importance of research evaluating when, and for whom, exercise becomes maladaptive, as well as research examining other characteristic features of maladaptive and adaptive exercise in EDs.

Abstract
Binge eating (BE) often develops during adolescence and is associated with deleterious psychological and physical consequences. Current treatments for adolescents achieve suboptimal results, likely due to failure to adequately address fear of weight gain (FOWG) which maintains BE. Thus, exposure treatment (the most powerful intervention for fear) may be a promising approach. However, exposure treatment has only minimally tested in adults with BE and never tested in adolescents. Thus, the current study is the first to evaluate a 4-session exposure module within a 12-session standard cognitive behavioral therapy for adolescents with BE. We recruited adolescents with BE (N = 5) and examined treatment feasibility, acceptability, and preliminary effects on FOWG and eating pathology. Overall, the 4-session exposure module was feasible and acceptable and showed preliminary evidence that it could reduce FOWG. However, several participants did not endorse significant fears of weight gain; rather, these participants reported that fears of deprivation or social judgment were more related to their BE. Future research should test higher doses of exposure and further examine the role of fear of deprivation/social judgment. Finally, future iterations of this treatment could include more parent involvement or test exposure in combination with treatments other than cognitive behavioral therapy, such as family-based treatment.

Abstract
Behavioral weight loss treatment (BT) for individuals with overweight and obesity is effective but leaves room for improvement. Mindfulness and acceptance-based treatments may bolster weight loss outcomes; yet, little is known about the efficacy of the individual components or the combinations of components that are most effective in producing weight loss above and beyond standard BT strategies for weight loss. This protocol manuscript describes the use of a multiphase optimization strategy to evaluate the independent and combinatory efficacy of three mindfulness and acceptance-based components (mindful awareness, willingness, values). Using a 2 × 2 × 2 factorial design, participants (N = 288) will be randomized to one of eight conditions, each representing a combination of core MABT strategies in addition to foundational BT strategies. Assessments occur at baseline, mid-treatment (week 24 through 26), post-treatment, and at 6, 12, and 24-month follow-up. The primary aim is to elucidate the independent efficacy of each MABT component on weight loss above gold-standard BT. The secondary aims are to evaluate the independent effect of these components on calorie intake, physical activity, and overall quality of life; evaluate target engagement (i.e., the degree to which each treatment component affects proposed mechanisms of action); and evaluate the potential moderating effect of susceptibility to internal and external food cues on outcomes. The exploratory aim is to quantify any component interaction effects (which may be synergistic, fully additive, or partially additive).

Abstract
A major contributor to the obesity epidemic is the overconsumption of high-calorie foods, which is partly governed by inhibitory control, that is, the ability to override pre-prepotent impulses and drives. Computerized inhibitory control trainings (ICTs) have demonstrated qualified success at affecting real-world health behaviors, and at improving weight loss, particularly when repeated frequently over an extended duration. It has been proposed that gamification (i.e., incorporating game-like elements such as a storyline, sounds, graphics, and rewards) might enhance participant interest and thus training compliance. Previous findings from a mostly female sample did support this hypothesis; however, it might be expected that the effects of gamification differ by gender such that men, who appear more motivated by gaming elements, stand to benefit more from gamification. The present study evaluated whether gender moderated the effect of a gamified ICT on weight loss. Seventy-six overweight individuals received a no-sugar-added dietary prescription and were randomized to 42 daily and 2 weekly ICTs focused on sweet foods that were either gamified or nongamified. Results supported the hypothesis that gamification elements had a positive effect on weight loss for men and not women (p = .03). However, mechanistic hypotheses for the moderating effect (in terms of enjoyment, compliance, and improvements in inhibitory control) were generally not supported (p's > .20). These results suggest that gamification of ICTs may boost weight loss outcomes for men and not women, but further research is needed to determine the specific mechanisms driving this effect and to arrive at gamification elements that enhance effects for both men and women.

Abstract
Caregivers and healthcare professionals (HPs) are increasingly concerned about childhood obesity. A critical consideration of caregivers and HPs is discussing weight status without provoking disordered eating. Given the complexity of these interacting concerns, major health advocacy groups have independently published guidelines for having conversations with children about overweight/obesity. The current investigation represented the first-ever systematic review of these guidelines to analyze their content, consistency, actionability, or scientific support. To conduct a systematic review, the authors performed a web-based search using the terms parent/HP, guidelines, child, and overweight/obesity that identified 59 guidelines on childhood obesity broadly, of which 13 provided explicit direction on how the caregiver or HP should approach a conversation about overweight with a child. Within these 13 guidelines, nine topic domains were identified: attitude modeling (covered by 31% of guidelines), behavior modeling (61%), dietary recommendations (54%), physical activity (46%), body acceptance and self-esteem (69%), conversation advice (92%), contact with HP (46%), talking about "weight" versus "overall health" (54%) and external factors (e.g., bullying, media) (54%). Although guidelines presented similar content, several inconsistencies in recommendations emerged. Notably, only three of the 13 guidelines referenced any scholarly sources and only a small minority of advice was actionable by caregivers or HPs. It is evident that guidelines for caregivers and HPs on speaking to children about obesity offer inconsistent advice, minimally based on empirical evidence. Future guidelines should aim to unify their messages for caregivers and HP and be better supported by empirical data.

Abstract
OBJECTIVE Although existing research supports the efficacy of mindfulness- and acceptance-based treatments (MABTs) for eating disorders (EDs), few studies have directly compared outcomes from MABTs to standard CBT. METHOD Participants (N = 44), treatment-seeking adults with bulimia-spectrum EDs, were screened for eligibility, consented, and randomized to receive 20 sessions of outpatient, individual CBT or MABT treatment. Treatment outcomes (binge eating and compensatory behavior episodes, global ED severity, depressive symptoms, quality of life, emotional awareness/clarity, distress tolerance, values-based decision-making, and emotion modulation) were measured at pre-treatment, post-treatment, and 6-month follow up. Data on feasibility and acceptability are also presented. RESULTS Treatment and assessment retention rates were comparable between MABT and CBT (p range = .51-.73) and between-group differences on acceptability measures were very small (d range = 0.03-0.19). Both conditions produced notable and generally comparable changes in most treatment outcomes at post-treatment (within group d range = 0.06-1.77). DISCUSSION The MABT and CBT conditions demonstrated comparable degrees of feasibility, acceptability, and symptom improvement, suggesting that MABTs warrant further evaluation as ED treatments.

Abstract
Reduced exposure to social reward during the COVID-19 pandemic may result in both reduced reward response to day-to-day life activities and elevated reward response to substances or naturally rewarding stimuli (e.g., food). The combined hypo- and hyper-reward responses results in a reward imbalance, which has been noted as a relevant maintenance factor for eating disorders (EDs) characterized by binge eating. This registered report describes the protocol for a pilot randomized controlled trial (RCT) comparing supportive therapy to a novel treatment targeting reward imbalance (Reward Re-Training; RRT) for individuals with binge eating. Aims of the current study include to confirm feasibility and acceptability of RRT, to evaluate the ability of RRT to engage critical targets, and to provide preliminary estimates of efficacy in reducing ED symptoms at both posttreatment and 3-month follow-up. Sixty participants will be randomized to either RRT or supportive therapy. For both conditions, treatment will be delivered in 10 weekly group outpatient therapy sessions conducted remotely using videoconferencing software. Assessments will be conducted at baseline, mid-treatment, posttreatment, and 3-month follow-up to measure feasibility, acceptability, critical treatment targets (i.e., reward to day-to-day life activities, reward to palatable foods, social isolation, and loneliness), and ED symptoms.

Abstract
Bulimia nervosa (BN) is characterized by a pattern of binge eating and compensatory behaviors as well as an overemphasis on body weight and shape in self-evaluation. Although cognitive behavioral therapy (CBT) is efficacious, recent reviews suggest that only 30% of patients reach abstinence at posttreatment. One potential reason for these poor outcomes is that CBT fails to adequately reduce elevated negative affect (NA) and shape and weight concern, which have been shown to be correlated with poorer treatment outcomes in BN. Therefore, novel treatment components that focus on improving NA and shape and weight concern are needed in order to enhance outcomes. Promoting physical activity (PA) is a promising avenue through which to reduce NA and improve body image in healthy individuals, other clinical populations (e.g., individuals with depression or anxiety), and individuals with eating disorders. While prescribing PA for individuals with BN has been controversial (due to concerns that exercise maybe be used to compensate for binge episodes or become driven or compulsive), this approach may have many benefits, including promoting healthy lifetime exercise habits that reduce likelihood of relapse through the improvement of emotion regulation skills and weight regulation. Given the promise of PA for targeting key maintenance factors of BN, we developed a 12-session healthy PA promotion intervention for BN and tested initial feasibility, acceptability, and preliminary target engagement in an iterative case series design (n = 3). The treatment provided cognitive-behavioral skills designed to identify, practice, and achieve behavioral goals while asking patients to engage in up to 150 minutes of moderate-to-vigorous PA per week, which was preplanned during each session with the client's therapist. Results suggested that the healthy PA promotion intervention was both feasible and acceptable to deliver. In addition, the intervention resulted in a clinically significant decrease in BN symptom frequency in each participant. Further, participants showed clinically significant decreases in NA and shape and weight concern. The current study demonstrates that healthy PA interventions can have beneficial effects on BN symptoms, NA, and shape and weight concern. However, due to the small sample size, conclusions must be treated with caution. Future research should investigate additional approaches for promoting healthy PA and include a larger sample in order to further test initial efficacy of this treatment approach.

Abstract
OBJECTIVE Existing screening tools are inadequate in differentiating binge eating from normative overeating in treatment-seeking individuals with overweight or obesity, as these individuals tend to overendorse loss-of-control (LOC; the hallmark characteristic of binge eating) on self-report measures. In order for treatment centers to efficiently and accurately identify individuals who would benefit from specialized treatment, it is critical to develop effective brief screening tools. This study examined the sensitivity and specificity of a self-report screener designed to be used by an outpatient treatment center on a large scale. METHODS Participants were treatment-seeking individuals (N = 364) with overweight or obesity who were administered the screener and who completed a subsequent interview assessing for LOC and binge eating. RESULTS Discriminant analyses revealed that the screener achieved 77.6% sensitivity and 77.0% specificity in predicting clinician-assessed LOC and 75.2% sensitivity and 74.1% specificity in predicting "full-threshold" binge eating (i.e., ≥12 objectively large binge-eating episodes within the past 3 months). Post hoc analyses indicated that male participants were more likely to be misclassified with the screener. CONCLUSIONS The self-report screener demonstrated satisfactory predictive ability, which is notable given the challenges of discriminating between LOC and normative overeating. However, room for improvement remains. In particular, the inclusion of additional screener items that more fully capture the binge-eating experience in males is warranted.

Abstract
Outcomes from cognitive behavioral therapy for binge-eating spectrum disorders are suboptimal, possibly due in part to deficits in self-regulation (i.e., the ability to control behavior in pursuit of long-term goals despite internal challenges). Mindfulness and acceptance-based treatments (MABTs) integrate behavioral treatment with psychological strategies designed to enhance self-regulation, yet little is known about how and for whom they are effective. The present study will utilize the multiphase optimization strategy to identify which of four MABT components (mindful awareness, distress tolerance, emotion modulation, values-based decision making) to include in a fully powered clinical trial. Participants (n = 256) will be randomized to 16 sessions in one of 16 conditions, each a different combination of MABT components being included or excluded from a base behavioral treatment. Our primary aim is to evaluate each component's independent efficacy on disordered eating symptoms. Our secondary aims are to confirm each component's target engagement (i.e., whether each component improves the targeted variable and outcomes), and test that each component's efficacy is moderated by baseline weaknesses in the same component (e.g., that participants with poor distress tolerance at baseline benefit most from the distress tolerance component). Our exploratory aim is to quantify the component interaction effects.

Abstract
There is ample evidence linking broad trait emotion regulation deficits and negative affect with loss-of-control (LOC)-eating among individuals with obesity and binge eating, however, few studies have examined emotion regulation at the state-level. Within and across day fluctuations in the ability to modulate emotion (or regulate emotional and behavioral responses), one facet of state emotion regulation, may be a more robust momentary predictor of LOC-eating than momentary negative affect and trait emotion regulation ability. As such, the current study tested if daily emotion modulation, and daily variability in emotion modulation differed on days with and without LOC-eating episodes, and if momentary emotion modulation was associated with subsequent LOC-eating episodes. For two weeks individuals (N = 14) with obesity and binge eating completed surveys as part of an ecological momentary assessment study. Participants reported on current ability to modulate emotion, LOC-eating, and current negative affect. On LOC-eating days compared to non-LOC-eating days, ability to modulate emotion was poorer (β =0.10, p < .001) and average variability in ability to modulation emotions was greater (β = 0.56, p = .008), even when controlling for negative affect. Greater momentary difficulty modulating emotion was associated with a 40% increase in subsequent risk for LOC-eating (ß = 0.34, p = .071, OR = 1.40). Findings from this pilot study suggest that individuals with obesity report poorer ability to modulate emotion and greater variability in ability to modulate emotion on LOC-eating days, even when controlling for negative affect. Future research should replicate findings and further elucidate the relationships between state emotion regulation, negative affect, and LOC-eating.

Abstract
BACKGROUND Executive functioning, which is fundamental for carrying out goal-directed behaviors, may be an underappreciated predictor of outcomes in lifestyle modification programs for adults with obesity. PURPOSE This study tested the hypotheses that higher levels of baseline executive functioning would predict greater weight loss and physical activity after 6 months of behavioral treatment. METHODS Participants (N = 320) were recruited from the community and provided with 16 treatment sessions. Executive functioning was measured with the tower task component of the Delis-Kaplan Executive Function System (D-KEFS). At months 0 and 6, weight was measured in the clinic and physical activity was measured with tri-axial accelerometers. RESULTS Baseline D-KEFS achievement score, rule violations, and completion time significantly predicted weight loss at 6 months. For example, among participants without any rule violations (n = 162), weight loss averaged 11.0%, while those with rule violations (n = 158) averaged 8.7% weight loss. Rule violations also significantly predicted physical activity at 6 months. Among participants without any rule violations, physical activity at 6 months averaged 169.8 min/week, versus 127.2 min/week among those with rule violations. CONCLUSIONS Particular aspects of executive functioning may predict the relative ease or difficulty of changing eating and exercise-related behaviors, albeit with small effect sizes. This study is the first to our knowledge to detect a predictive relationship between components of executive functioning and objectively measured physical activity in adult lifestyle modification, and one of the first to predict weight loss in adults using an objective measure of executive functioning.

Abstract
OBJECTIVE Although binge eating is associated with impulsivity, clinical reports suggest that some individuals with bulimia nervosa (BN) and binge eating disorder (BED) plan binge episodes in advance. This study is the first to examine: (1) the frequency of binge planning (BP; defined as both advanced knowledge that a binge episode will occur and taking steps to facilitate the binge episode); (2) associations of BP with ED severity, and (3) whether BP serves a negative reinforcement function. METHOD Patients with BN- and BED-spectrum eating disorders (EDs; n = 111) were administered semi-structured interview questions regarding BP. RESULTS Results indicate that a substantial minority of patients (27.8%) engage in BP. BP was significantly more common in BN versus BED-spectrum EDs (38.3% versus 20.6%, p = 0.04) and in those who did versus did not endorse self-induced vomiting (50.0% versus 21.3%, p < 0.01). Frequency of BP was positively associated with overall ED psychopathology (r = 0.19, p < 0.05). Exploratory analyses indicated that approximately two-thirds (67.7%) reported that BP served to distract from unpleasant experiences. DISCUSSION BP is present for a significant subset of patients and may play a critical role in the reinforcement cycles of binge eating. Future research should further elucidate the function of BP to inform treatment development.

Abstract
Outcomes from cognitive behavioral therapy (CBT) for bulimia nervosa (BN) and binge-eating disorder (BED) are suboptimal. One potential explanation is that CBT fails to adequately target inhibitory control (i.e., the ability to withhold an automatic response), which is a key maintenance factor for binge eating. Computerized inhibitory control training (ICT) is a promising method for improving inhibitory control but is relatively untested in BN/BED. The present study will evaluate a computer-based ICT as an adjunct to CBT for BN/BED. Participants with BN (n = 30) or BED (n = 30) will be randomized to 12 weeks of either CBT + ICT or CBT + a sham training. Trainings will be completed daily for 4 weeks and weekly for 8 weeks. Primary aims include the following: (a) confirm target engagement (evaluate whether ICT improves inhibitory control), (b) test target validation (evaluate whether improvements in inhibitory control are associated with improvements in binge eating), and (c) evaluate the incremental efficacy of ICT on binge eating. Secondary aims include the following: (a) evaluate ICT feasibility and acceptability and (b) assess the moderating effects of approach tendencies on highly palatable food, dietary restraint, and diagnosis. Data will be used to shape a fully powered clinical trial designed to assess efficacy and dose-response effects of ICT for BN/BED.

Abstract
INTRODUCTION Many individuals engaged in behavioral weight loss make suboptimal increases in moderate-to-vigorous physical activity (MVPA). Theoretically, reductions in negative affect could reinforce MVPA. However, little work has been done investigating the association between facets of negative affect (e.g., average levels of negative affect, variability in negative affect) and MVPA among individuals attempting to increase MVPA as part of a behavioral weight loss attempt. METHODS Participants (n = 139) provided data at month 6 of a year-long behavioral weight loss program (at which point the prescription for MVPA had reached the highest level). Participants wore an accelerometer and provided EMA ratings of affect over the same week. RESULTS Individuals engaged in more frequent and longer periods of MVPA had lower average negative affect and variability in negative affect across the assessment period. Lower negative affect one day predicted greater time spent in MVPA on the next day; lower variability in negative affect than one's average level also predicted greater time spent in MVPA on the next day. Greater engagement in MVPA than one's own mean on one day did not predict mean or variability in affect. DISCUSSION Engaging in MVPA over time may reduce negative affect, while lower negative affect may increase motivation to engage in MVPA. Importantly, day-to-day effects indicated that affect is an important acute predictor of MVPA behavior. It is possible that individuals, particularly those with higher negative affect or variability in negative affect, may benefit from the inclusion of skills to manage negative affect in programs prescribing physical activity.
