RESUMO

BACKGROUND: Avoidant/restrictive food intake disorder (ARFID) and anorexia nervosa (AN) are the two primary restrictive eating disorders; however, they are driven by differing motives for inadequate dietary intake. Despite overlap in restrictive eating behaviors and subsequent malnutrition, it remains unknown if ARFID and AN also share commonalities in their cognitive profiles, with cognitive alterations being a key identifier of AN. Discounting the present value of future outcomes with increasing delay to their expected receipt represents a core cognitive process guiding human decision-making. A hallmark cognitive characteristic of individuals with AN (vs. healthy controls [HC]) is reduced discounting of future outcomes, resulting in reduced impulsivity and higher likelihood of favoring delayed gratification. Whether individuals with ARFID display a similar reduction in delay discounting as those with AN (vs. an opposing bias towards increased delay discounting or no bias) is important in informing transdiagnostic versus disorder-specific cognitive characteristics and optimizing future intervention strategies. METHOD: To address this research question, 104 participants (ARFID: n = 57, AN: n = 28, HC: n = 19) completed a computerized Delay Discounting Task. Groups were compared by their delay discounting parameter (ln)k. RESULTS: Individuals with ARFID displayed a larger delay discounting parameter than those with AN, indicating steeper delay discounting (M ± SD = -6.10 ± 2.00 vs. -7.26 ± 1.73, p = 0.026 [age-adjusted], Hedges' g = 0.59), with no difference from HC (p = 0.514, Hedges' g = -0.35). CONCLUSION: Our findings provide a first indication of distinct cognitive profiles among the two primary restrictive eating disorders. The present results, together with future research spanning additional cognitive domains and including larger and more diverse samples of individuals with ARFID (vs. AN), will contribute to identifying maintenance mechanisms that are unique to each disorder as well as contribute to the optimization and tailoring of treatment strategies across the spectrum of restrictive eating disorders.


Avoidant/restrictive food intake disorder (ARFID) and anorexia nervosa (AN) are both restrictive eating disorders. However, the reasons for restricting food intake differ between the two diagnoses. A key question in further understanding similarities and differences between ARFID and AN is to understand whether individuals with these disorders process information and make decisions in similar or distinct ways. When humans decide between two different outcomes (e.g., a smaller immediate or a larger delayed reward), outcomes decrease in their value the farther in the future we expect to receive them (delay discounting). Individuals with AN exhibit a reduced discounting of future outcomes, which makes them more likely to forego immediate gratification for later rewards. However, whether this holds true for individuals with ARFID too (or whether they show the opposite or no bias) is unknown. Our investigation is the first to compare delay discounting between individuals with ARFID, AN, and healthy controls (HC). Our results show that individuals with ARFID show more delay discounting than those with AN, with no difference from HC. Knowing how rewards are being chosen and decisions made (and knowing differences between diagnoses) will be helpful in further optimizing and tailoring treatments for restrictive eating disorders.

RESUMO

OBJECTIVE: Although exercise is generally considered healthy, many individuals engage in maladaptive exercise (e.g., compulsive in nature). Several definitions of maladaptive exercise exist, leading to multiple, varied assessment tools; assuming homogeneity across these assessments contributes to low consensus in etiological models. METHOD: We used a Jaccard Index to quantify content overlap among 15 commonly-used self-report instruments measuring maladaptive exercise, with 31 features identified across 224 items. RESULTS: The most common features were exercise to control weight/shape and to avoid negative affect (both included in 9/15 instruments), or compensate for calories consumed (8/15 instruments). Overlap among instruments was low (.206) and no features were common across all instruments. CONCLUSIONS: Findings generally support theoretical models of exercise in eating pathology. However, instruments most commonly used to assess maladaptive exercise measure heterogenous content. Careful consideration should be taken when comparing findings derived from differing instruments, when synthesizing literature on maladaptive exercise, and when selecting instruments to measure specific maladaptive exercise features. PUBLIC SIGNIFICANCE: Many, varied, tools exist for the assessment of maladaptive exercise (e.g., compulsive or compensatory) in the context of eating disorders. Assuming homogeneity across tools contributes to low consensus in the field. We used a Jaccard Index to quantify content overlap among 15 self-report instruments measuring maladaptive exercise. The most commonly used instruments measure heterogenous content. Careful consideration should be taken when synthesizing literature and selecting instruments to use in research.

RESUMO

OBJECTIVE: Previous work has outlined cognitive beliefs about exercise in general, but very little is known about momentary cognitions while engaging in pathological exercise. The primary aim of this study was to explore thought content during exercise and to test whether these thoughts predicted later engagement in eating disorder behaviors. We also tested associations between thoughts and specific exercise activity. METHOD: We monitored 31 women with clinically significant eating psychopathology for 3 weeks via ecological momentary assessment as they reported on their exercise and eating disorder behaviors, and thoughts about shape, weight, or calories during exercise. Thoughts were self-reported upon cessation of each exercise session. RESULTS: Thinking about weight loss during exercise predicted later engagement in body-checking behaviors. Weight-bearing exercise was associated with a decreased likelihood of thinking about calories but an increased likelihood of thinking about shape during exercise. DISCUSSION: These findings show that shape and weight thoughts are present during exercise and that their influence on eating disorder behaviors may exist on a much briefer time scale (i.e., within a day) than previous studies show. Clinically, future studies may seek to test interventions aimed at changing or restructuring cognitions during exercise to help shape adaptive exercise behavior during and after treatment. PUBLIC SIGNIFICANCE: This is the first study measuring thoughts during pathological exercise in real-time among those with eating disorder psychopathology. The results show that thinking about weight loss during exercise might increase the likelihood of engaging in body-checking behaviors. Findings will inform the development of treatment approaches to help those in recovery from eating disorders re-engage with exercise.

RESUMO

OBJECTIVE: Pathological exercise is a dangerous behavior often observed in eating disorders. Data investigating associated characteristics of pathological exercise in men are lacking, despite college men and women being at equally elevated risk for developing eating disorders. PARTICIPANTS: Two hundred and twenty-four college men who exercise regularly completed a series of self-report questionnaires. METHODS: Latent profile analysis was used to identify empirically-derived homogenous subgroups of regular exercisers based on severity of other eating disorder attitudes and behaviors. Profiles were also compared on differences in exercise motivation and general psychopathology (i.e., depression, anxiety). RESULTS: Fit indices indicated a three-profile solution. Profiles described an eating psychopathology group, a low psychopathology group, and a high exercise frequency group without eating disorder features. CONCLUSIONS: Pathological exercise cannot be identified using exercise frequency alone. Other features like body dissatisfaction and exercise motivation style are relevant in identifying pathological exercise behavior in college men.

RESUMO

Dialectical behavior therapy (DBT) is an empirically supported behavioral treatment for individuals with borderline personality disorder who frequently exhibit life-threatening behavior, such as suicide attempts, nonsuicidal self-injury urges and actions, and suicidal ideation. We provide an overview of the theoretical framework by which DBT conceptualizes these life-threatening behaviors and the principles by which safety planning measures are implemented and maintained throughout treatment. The importance of orienting clients to treatment and obtaining their commitment to decrease life-threatening behavior is reviewed. Relevant strategies associated with risk management and assessment, such as the diary card, chain analysis, solution analysis, phone coaching, and consultation team, are described. The overview concludes with a case example to illustrate the application of these techniques with a DBT client with a long-standing history of engaging in life-threatening behaviors.

RESUMO

Individuals with eating disorders (EDs) are at significant risk for increases in symptomatology and diminished treatment access during the COVID-19 pandemic. Environmental precautions to limit coronavirus spread have affected food availability and access to healthy coping mechanisms, and have contributed to weight-stigmatizing social media messages that may be uniquely harmful to those experiencing EDs. Additionally, changes in socialization and routine, stress, and experiences of trauma that are being experienced globally may be particularly deleterious to ED risk and recovery. This paper presents a brief review of the pertinent literature related to the risk of EDs in the context of COVID-19 and offers suggestions for modifying intervention efforts to accommodate the unique challenges individuals with EDs and providers may be experiencing in light of the ongoing public health crisis.

RESUMO

Pathological exercise in anorexia nervosa (AN) is a harmful behavior associated with a chronic course and poor prognosis. To date, no comprehensive theoretical model exists to describe pathological exercise in the context of AN, and as such, few treatments are effective at promoting direct and sustained pathological exercise extinction. Using a framework put forth by Wise & Koob (2014), debating the relative importance of positive and negative reinforcement in substance use, we present three hypotheses of behavioral reinforcement of exercise, encompassing biological, psychological, and environmental influences. Specifically, we argue that exercise is positively reinforced through receipt of biological and behavioral rewards, negatively reinforced through avoidance of aversive emotions, and that these two systems work in tandem over time to engrain pathological exercise as a habit. We then present suggestions for testing each of these hypotheses as future directions for the field.

RESUMO

Cognitive inflexibility and attention to detail bias represent a promising target in eating disorder (ED) treatment. While prior research has found that adults with eating disorders exhibit significant cognitive inflexibility and heightened attention to detail, less is known about these cognitive impairments among adolescents, and across EDs transdiagnostically. To address this gap, adolescent females (N = 143) from a residential ED program with anorexia nervosa, bulimia nervosa, or other specified feeding or eating disorder completed the Detail and Flexibility Questionnaire (DFlex) and measures of ED and general psychopathology. Transdiagnostically, adolescents with EDs scored higher than an archival sample of healthy control adolescents on both cognitive rigidity (p < .001; Cohen's d = 1.92) and attention to detail (p < .001; Cohen's d = 1.16). These cognitive impairments were significantly associated with severity of eating pathology, and these relationships existed independent of age, duration of illness, or body mass index (BMI). Our findings suggest cognitive inflexibility and heightened attention to detail occur transdiagnostically in adolescents with eating disorders and are unlikely to be a scar of the disorder. Future prospective research is needed to determine whether these cognitive styles represent an endophenotype of eating disorders.

RESUMO

OBJECTIVE: Pathological exercise is common among those with eating disorders and has typically been characterized as excessive, compulsive, or compensatory in nature. Little is known about how pathological exercise is associated with other eating disorder behaviors or personality traits, or whether these associations differ between men and women. METHOD: We used hierarchical dimensional modeling in three samples, including college women (N = 205), women with eating psychopathology (N = 268), and college men (N = 235), to examine latent associations between pathological exercise and eating disorder psychopathology, namely compulsivity, emotion regulation, and body dissatisfaction. RESULTS: Using Goldberg's (2006) "bass-ackwards" method, we identified separate 10-factor solutions (women) or an 11-factor solution (men). A distinct muscle building factor arose in the three-factor solution for men, and it also notably arose in the six- and eight-factor solutions for community and college women, respectively, highlighting an important understudied motivation factor in both healthy and pathological exercise. Each solution accounted for 64.8% (college women), 51.9% (women with eating psychopathology), and 43.9% (college men) of the variance in excessive exercise, respectively. DISCUSSION: Findings indicate that pathological exercise is associated with different psychological traits (e.g., poor emotion regulation, compulsivity) across populations, and such differences may necessitate unique treatment approaches tailored accordingly.

RESUMO

The role of positive emotion in anorexia nervosa (AN) has been underappreciated in both theory and treatment. Yet, people with AN demonstrate high motivation for and sustained effort toward weight loss, achieving success to an extreme beyond the capability of most people. Positive emotion dysregulation may facilitate and reinforce such efforts. The positive emotion amplification (PE-AMP) model of AN describes a dynamic interplay between biologically based enhanced reward responding and cognitive-behavioral factors that amplify positive emotion, resulting in positive feedback cycles that motivate and reinforce weight loss behavior during the AN onset phase. These experiences subvert the pursuit of happiness by providing artificial senses of autonomy, competency, and relatedness to others (self-determination theory; Ryan & Deci, 2000) that provide a stark contrast to an otherwise negative emotional environment, resulting in the emergence and persistence of AN psychopathology as a self-sustaining sense of purpose. Ultimately, negative emotion, PE dysregulation, and artificial self-determination threats continue to drive AN behavior during the AN maintenance phase, pushing patients toward a genuine self-determination breakdown that can lead to hospitalization, health crises, relational strife and diminished quality of life, or even manifest in suicidal behavior. Future research directions and novel methodological approaches inspired by the PE-AMP model are discussed, as are important treatment implications for addressing this highly treatment-resistant disorder.

RESUMO

Smokers report weight and appetite control as motivators to smoking continuance. These concerns are particularly salient for smokers who use cigarettes to suppress appetite and manage weight. Dieting may influence weight, shape, and appetite-related smoking motivation; however, this has not yet been examined. This study tested associations between five diet types and smoking motivation to control weight, shape, and appetite among adult daily cigarette smokers (N = 550). A multivariate analysis was used to test the incremental association between diet types and Smoking-Related Weight and Eating Episodes Test (SWEET) subscales, adjusting for age, body mass index, sex, and cigarette dependence. Smokers who diet (n = 83, 15.1%) reported higher scores on all SWEET subscales compared to smokers not on a diet. Low-calorie dieting was associated with greater smoking motivation to cope with body dissatisfaction, and low-sugar dieting was associated with greater motivation for smoking to prevent withdrawal-related appetite increases. Treatment implications for smoking cessation are discussed.

RESUMO

BACKGROUND: Distress intolerance, one's inability to withstand distressing emotional or physical states, is a transdiagnostic vulnerability implicated in affect-based health behaviors, including cigarette smoking and poor weight control. The current study evaluated associations between distress intolerance and the reliance on cigarettes for management of weight, appetite, or body dissatisfaction, which may pose a burden for cessation and increase risk of weight-related health problems. METHOD: Daily smokers (n = 577) completed an online survey assessing distress tolerance and reliance on cigarettes for weight and shape control with the four subscales of the Smoking and Weight Eating Episodes Test (SWEET). Four hierarchical regression models were constructed to test the association between distress intolerance and SWEET scores, accounting for the effect of relevant covarying factors. RESULTS: After adjusting for model covariates, distress intolerance was significantly incrementally associated with greater tendency to rely on cigarettes to suppress appetite (adjR2 = .040), prevent overeating (adjR2 = .034), cope with body dissatisfaction (adjR2 = .046), and cope with nicotine withdrawal-related appetite increases (adjR2 = .030). CONCLUSION: Distress intolerance may play an etiological role in maladaptive use of cigarettes to control appetite, weight, and body dissatisfaction among daily smokers, particularly those with weight- or shape-related concerns. Interventions aimed at increasing perceived ability to withstand distress could potentially reduce reliance on cigarettes for the aforementioned purposes.

RESUMO

OBJECTIVE: The cognitive-behavioral therapy (CBT) model of eating disorders suggests that compensatory purging behaviors (e.g., self-induced vomiting, inappropriate laxative use) are primarily driven by binge eating. However, many individuals endorse purging in the absence of binge eating (i.e., noncompensatory purging [NCP]). Research is needed to understand why some individuals purge in the absence of objective or subjective binge-eating episodes. METHOD: Given the importance of overvaluation of shape/weight in the CBT model, and the existing evidence linking temperamental characteristics like behavioral inhibition (i.e., the tendency to withdraw in response to threat cues) with purging in general, we tested whether behavioral inhibition moderated the relationship between overvaluation of shape/weight and NCP in a sample of individuals in a residential eating disorder treatment center (N = 143). RESULTS: Overvaluation was more strongly related to NCP in individuals with high (relative to low) levels of behavioral inhibition. Among individuals low in behavioral inhibition, overvaluation predicted engagement in NCP to a much weaker extent. DISCUSSION: For those high (relative to low) in behavioral inhibition, both emotional avoidance and overvaluation may be important targets in the treatment of NCP, particularly in the absence of binge eating.

RESUMO

Anorexia nervosa (AN) is a complex and life-threatening eating disorder. Current models of AN onset and maintenance have largely focused on the role of negative affect, while fewer models have described the role of positive affect (PA). Given that these theoretical models have informed current treatment approaches, and that treatment remains minimally effective for adults with AN, we advocate that targeting PA is one avenue for advancing maintenance models and by extension, treatment. We specifically propose that AN may arise and be chronically and pervasively maintained as a function of dysregulated PA in response to weight loss and weight loss behaviors (e.g., restriction, excessive exercise), to a degree that is not accounted for in existing models of AN. We present evidence from multiple domains, including biological, behavioral, and self-report, supporting the hypothesis that PA dysregulation in AN contributes to the maintenance of the disorder. We conclude with several specific avenues for treatment development research as well as a call for future work elucidating the biological correlates of PA.

RESUMO

OBJECTIVE: This virtual issue of the International Journal of Eating Disorders highlights recently published research that aligns with the broad themes of the 2019 International Conference on Eating Disorders (ICED), held in New York, NY, USA. METHODS AND RESULTS: We selected articles that were published between 2017 and 2019 that complement the content of the keynote and plenary sessions. We also curated additional articles from early career scholars, given that an important component of the annual ICED is to foster the development and training of the next generation of eating-disorder clinicians and researchers. DISCUSSION: We hope that this virtual issue will spark more in-depth discussion and reflection on the topics, questions, and critical advances in the field of eating disorders that were presented at the 2019 ICED.

RESUMO

OBJECTIVE: Avoidant/restrictive food intake disorder (ARFID) and anorexia nervosa (AN) are restrictive eating disorders. There is a proposal before the American Psychiatric Association to broaden the current DSM-5 criteria for ARFID, which currently require dietary intake that is inadequate to support energy or nutritional needs. We compared the clinical presentations of ARFID and AN in an outpatient sample to determine how a more inclusive definition of ARFID, heterogeneous for age and weight status, is distinct from AN. METHODS: As part of standard care, 138 individuals with AN or ARFID completed an online assessment battery and agreed to include their responses in research. RESULTS: Individuals with ARFID were younger, reported earlier age of onset, and had higher percent median BMI (%mBMI) than those with AN (all ps < .001). Individuals with ARFID scored lower on measures of eating pathology, depression, anxiety, and clinical impairment (all ps < .05), but did not differ from those with AN on restrictive eating (p = .52), and scored higher on food neophobia (p < .001). DISCUSSION: Allowing psychosocial impairment to be sufficient for an ARFID diagnosis resulted in a clinical picture of ARFID such that %mBMI was higher (and in the normal range) compared with AN. Differences in gender distribution, age, and age of onset remained consistent with previous research. Both groups reported similar levels of dietary restriction, although ARFID can be distinguished by relatively higher levels of food neophobia. Currently available measures of eating pathology may capture certain ARFID symptoms, but highlight the need for measures of impairment relative to ARFID.

RESUMO

OBJECTIVE: This study examined whether patterns of eating-disorder (ED) psychopathology differed by gender across DSM-5 severity specifiers in anorexia nervosa (AN) and bulimia nervosa (BN). METHOD: We tested whether ED psychopathology differed across DSM-5 severity specifiers among 532 adults (76% female) in a residential treatment center with AN or BN. We hypothesized that severity of ED psychopathology would increase in tandem with increasing severity classifications for both males and females with AN and BN. RESULTS: Among females with BN, DSM-5 severity categories were significantly associated with increasing ED psychopathology, including Eating Disorder Examination-Questionnaire dietary restraint, eating concern, shape concern, and weight concern; and Eating Disorder Inventory drive for thinness and bulimia. ED psychopathology did not differ across DSM-5 severity levels for males with BN. For both males and females with AN, there were no differences in ED psychopathology across severity levels. DISCUSSION: Results demonstrate that DSM-5 severity specifiers may function differently for males versus females with BN. Taken together, data suggest DSM-5 severity specifiers may not adequately capture severity, as intended, for males with BN and all with AN. Future research should evaluate additional clinical validators of DSM-5 severity categories (e.g., chronicity, treatment non-response), and consider alternate classification schemes.

RESUMO

The Eating Pathology Symptoms Inventory (EPSI) is a 45-item self-report measure of eating pathology designed to be sensitive in assessing symptoms among diverse populations of individuals with disordered eating. The current study represents the first external validation of the EPSI as well as the first to examine the factor structure in an outpatient eating disorder clinic sample. We conducted an exploratory factor analysis in three separate samples: an outpatient clinic sample (n = 284), a college sample (n = 296), and a community sample (n = 341) and compared the observed factor structures to the original 8-factor solution proposed by Forbush et al. (2013). We also investigated whether the subscales correlated with the Eating Disorder Examination Questionnaire (EDE-Q) and a clinical impairment measure among the outpatient clinic sample. Results suggested between 7 and 8 factors for each of the three samples. Our findings largely replicated those of the original EPSI development study, excepting some deviations in the Muscle Building, Cognitive Restraint, and Excessive Exercise subscales. However, confirmatory factor analysis and exploratory structural equation modeling produced poor model fit, which may be related to the item heterogeneity within many of the subscales. Finally, eating disorder attitudes and behaviors assessed by the EPSI were significantly correlated with the EDE-Q and with clinical impairment. Overall, our results highlight both strengths and limitations of the EPSI. Findings provide preliminary support for the use of the EPSI among research with diverse populations, and present several avenues for future research for enhancing clinical utility.

RESUMO

OBJECTIVE: The objective of this study was to investigate predictors of long-term recovery from eating disorders 22 years after entry into a longitudinal study. METHOD: One hundred and seventy-six of the 228 surviving participants (77.2%) were re-interviewed 20-25 years after study entry using the Longitudinal Interval Follow-up Evaluation to assess ED recovery. The sample consisted of 100 women diagnosed with anorexia nervosa (AN) and 76 with bulimia nervosa (BN) at study entry. RESULTS: A comorbid diagnosis of major depression at the start of the study strongly predicted having a diagnosis of AN-Restricting type at the 22-year assessment. A higher body mass index (BMI) at study intake decreased the odds of being diagnosed with AN-Binge Purge type, relative to being recovered, 22 years later. The only predictor that increased the likelihood of having a diagnosis of BN at the 22-year assessment was the length of time during the study when the diagnostic criteria for BN were met. CONCLUSIONS: Together, these results indicate that the presence and persistence of binge eating and purging behaviors were poor prognostic indicators and that comorbidity with depression is particularly pernicious in AN. Treatment providers might pay particular attention to these issues in an effort to positively influence recovery over the long-term.

RESUMO

OBJECTIVE: Anxiety is a risk factor for disordered eating, but the mechanisms by which anxiety promotes disordered eating are poorly understood. One possibility is local versus global cognitive processing style, defined as a relative tendency to attend to details at the expense of the "big picture." Anxiety may narrow attention, in turn, enhancing local and/or compromising global processing. We examined relationships between global/local processing style, anxiety, and disordered eating behaviors in a transdiagnostic outpatient clinical sample. We hypothesized that local (vs. global) processing bias would mediate the relationship between anxiety and disordered eating behaviors. METHOD: Ninety-three participants completed the eating disorder examination-questionnaire (EDE-Q), State-Trait Anxiety Inventory (STAI)-trait subscale, and the Navon task (a test of processing style in which large letters are composed of smaller letters both congruent and incongruent with the large letter). The sample was predominantly female (95%) with a mean age of 27.4 years (SD = 12.1 years). RESULTS: Binge eating, but not fasting, purging, or excessive exercise, was correlated with lower levels of global processing style. There was a significant indirect effect between anxiety and binge eating via reduced global level global/local processing. DISCUSSION: In individuals with disordered eating, being more generally anxious may encourage a detailed-oriented bias, preventing individuals from maintaining the bigger picture and making them more likely to engage in maladaptive behaviors (e.g., binge eating).
