Feasibility and Acceptability of Brief Behavioral Treatment for Insomnia After Eating Disorder Treatment: The TIRED Study.

Objective: The purpose of this pilot trial was to evaluate the novel use of Brief Behavioral Treatment for Insomnia (BBTI) for people with residual insomnia disorder following eating disorder (ED) treatment.

Methods: Participants (N = 6) completed a multiple-baseline design study of BBTI. The primary outcome was insomnia severity, measured by the Insomnia Severity Index.

From Consensus to Innovation: Advancing the Science of Eating-Disorder Measurement.

This commentary is a response to the article written by Reilly et al. (2025). The authors discuss the Eating Disorder Examination (EDE), asserting that critiques of the EDE reflect a larger assessment issue within the field.

Preliminary development and validation of the Eating Pathology Clinical Outcomes Tracker.

There are few routine outcomes monitoring (ROM) tools available to track changes in eating-disorder (ED) symptom expression. Given that ROM is critical for providing measurement-based care, there is a pressing need to develop ROM tools for EDs. The present study developed and validated the Eating Pathology Clinical Outcomes Tracker (EPCOT).

Ecological momentary assessment of between- and within-person sleep quality as a predictor of disordered eating behaviors among young women with disordered eating.

Although disordered eating and sleep problems often co-occur, there has been limited research on mechanisms underlying their association. Previous studies using ecological momentary assessment (EMA) to evaluate links between sleep quality and disordered eating behaviors (e.g.

Associations between intraindividual variability in weekday-weekend sleep timing and duration and eating disorder pathology.

Sleep disruptions may be risk factors for eating disorder symptoms. However, mean estimates of sleep characteristics may not be ideal metrics, considering many individuals have irregular sleep patterns. Although variability in sleep-wake timing is associated with irregular eating patterns among individuals with eating disorders (Linnaranta et al.

Do empirically-derived personality subtypes relate to cognitive inflexibility in anorexia nervosa and bulimia nervosa?

Background: Accruing evidence suggests that personality-based approaches to eating disorder classification may offer several advantages over current diagnostic models, with prior research consistently identifying three personality-based groups characterized by either (1) high levels of impulsivity and dysregulation (termed the "undercontrolled" group), (2) high levels of rigidity and avoidance (termed the "overcontrolled" group), or (3) relatively normative levels of personality functioning (termed the "low psychopathology" group). Cognitive inflexibility (i.e.

State of the Science: The Hierarchical Taxonomy of Psychopathology (HiTOP).

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a dimensional framework for psychopathology advanced by a consortium of nosologists. In the HiTOP system, psychopathology is grouped hierarchically from super-spectra, spectra, and subfactors at the upper levels to homogeneous symptom components and maladaptive traits and their constituent symptoms, and maladaptive behaviors at the lower levels. HiTOP has the potential to improve clinical outcomes by planning treatment based on symptom severity rather than heterogeneous diagnoses, targeting treatment across different levels of the hierarchy, and assessing distress and impairment separately from the observed symptom profile.

Using item response theory to identify key symptoms of insomnia in a sample of university students with probable eating disorders.

Purpose: Researchers have theorized that interactions between appetitive and circadian disruptions result in increased eating disorder (ED) symptoms and insomnia. However, it is unclear how specific insomnia symptoms present among people with EDs and if the latent structure of insomnia in this population is similar to that of people with insomnia disorder.

Methods: We conducted a secondary analysis of data collected on ED and insomnia symptoms using a subset of students (N = 547; 79.

Habitual behavioural control moderates the relation between daily perceived stress and purging.

Objective: Evidence suggests that interpersonal stress plays a role in maintaining binge eating and purging (e.g., self-induced vomiting, misuse of laxatives).

Behaviourally assessed negative urgency is uniquely associated with binge-eating frequency.

Objective: Binge eating appears to be associated with impulsivity, especially in response to negative affect (i.e., negative urgency).

The Integration of Sleep Research Into Eating Disorders Research: Recommendations and Best Practices.

Objective: Sleep disturbance is common among individuals with eating disorders (EDs), with approximately 50% of patients with EDs reporting sleep disturbance. Sleep problems may promote, exacerbate, or maintain ED symptoms through a variety of hypothesized mechanisms, such as impaired executive function, increased negative affect, and disruptions to appetitive rhythms. Although research investigating the role of sleep in EDs is growing, the current literature suffers from methodological limitations and inconsistencies, which reduce our ability to translate findings to improve clinical practice.

Dysphoric mood may explain the relation between sleep reactivity and binge eating but not purging.

This study investigated whether sleep reactivity (i.e., a propensity to experience sleep disturbances when stressed) relates to eating disorder behavioral symptoms indirectly through dysphoric mood in a sample of college students.

Fear of negative evaluation and intolerance of uncertainty: Assessing potential internalizing correlates of eating disorder-related clinical impairment and differences across diagnostic presentations.

The Hierarchical Taxonomy of Internalizing Dimensions for Eating Disorders model positions eating disorder (ED) symptoms on an internalizing dimension alongside anxiety and mood symptoms. Symptom dimensions falling under the internalizing subfactors of distress (e.g.

Changes in evening-shifted loss of control eating severity following treatment for binge-eating disorder.

Background: Loss of control eating is more likely to occur in the evening and is uniquely associated with distress. No studies have examined the effect of treatment on within-day timing of loss of control eating severity. We examined whether time of day differentially predicted loss of control eating severity at baseline (i.

Prospective associations between cognitive flexibility and eating disorder symptoms in anorexia nervosa and bulimia nervosa.

This study investigated concurrent and prospective associations between measures of reversal learning and attentional set-shifting and eating disorder symptoms at baseline, 3 months, and 6 months among individuals with anorexia nervosa restricting subtype (AN-R, n = 26), AN binge eating/purging subtype (AN-BP, n = 22), bulimia nervosa (BN, n = 35), and healthy controls (n = 27), and explored whether these associations differed by diagnosis. At baseline, participants completed diagnostic interviews, height/weight measurements, and measures of set-shifting (the Intradimensional/Extradimensional shift task) and reversal learning (a probabilistic reversal learning task). At 3- and 6-month follow-up, participants with eating disorders completed assessments of weight and eating disorder symptoms.

Eating Disorder Treatment Dropout: What Factors Influence Access to Specialty Care in an Underresourced Appalachian Region?

Appalachia is uniquely impacted by healthcare disparities. Outpatient dropout rates remain a significant barrier for individuals necessitating specialty eating disorder (ED) treatment. We explored factors impacting patient continuation in specialty outpatient care for EDs.

Responses to bright light exposure in individuals with binge-spectrum eating disorders characterized by high dietary restraint and negative affect.

Objective: Circadian rhythm disruptions are associated with binge eating, can be causal of negative mood, and may be corrected with bright light exposure. A subtype of individuals with binge-spectrum eating disorders are characterized by combined high dietary restraint and negative affect. These individuals have higher eating disorder psychopathology and poorer treatment response.

Loss of control eating exhibits an evening diurnal shift among females with bulimia nervosa and binge-eating disorder.

Loss of control (LOC) is a hallmark feature of binge eating that is associated with significant distress and impairment. Despite the central role diurnal rhythms may play in the development and maintenance of LOC eating, diurnal patterns of LOC remain understudied and poorly characterised. We assessed the diurnal timing of LOC in a sample of females with bulimia nervosa and binge-eating disorder who participated in a study assessing the impact of bright light exposure on binge eating, hypothesising that higher ratings of LOC would be more likely to occur later in the day.

Reconceptualizing emotion regulation and coping strategy usage in eating disorders research: The utility of a regulatory flexibility framework.

Emotion regulation and coping strategies are often conceptualized in eating disorder (ED) research as inherently adaptive or maladaptive, and successful regulation is often defined as greater overall use of adaptive strategies. However, recent empirical work outside of the field of EDs challenges this categorical conceptualization of strategies, demonstrating that adaptiveness is determined by the ability to flexibly implement and adjust strategies based on contextual demands (i.e.

Characterizing naturalistic meal timing, energy intake, and macronutrient intake among individuals with loss of control eating.

Binge eating demonstrates an evening diurnal shift among individuals with eating disorders. Disruptions to diurnal appetitive rhythms may be somewhat chronic and set the stage for additional disruptions to prompt binge eating. Despite known diurnal shifts in binge eating and related constructs (e.

Delusionality of beliefs among 50 adult females with severe and extreme anorexia nervosa upon admission to an acute medical stabilization facility.

We aimed to evaluate whether the content of eating/body image-related beliefs in individuals with anorexia nervosa (AN) was associated with important aspects of eating disorder (ED) psychopathology. Females with AN completed assessments within 96 hours of admission to an inpatient medical stabilization program. Study staff administered the Brown Assessment of Beliefs Scale and participants completed self-report measures.

Development and validation of a scale for the tendency to exercise in response to mood, eating, and body image cues: the Reactive Exercise Scale (RES).

Purpose: Earlier work on engaging in physical exercise when experiencing negative affect demonstrated robust associations with eating disorder (ED) behaviors and attitudes; however, measurement of the behavior was primitive, relying on one yes/no question that cannot capture much variability. We report on the development of a self-report measure, the Reactive Exercise Scale (RES), that disentangles the tendency to engage in exercise in response to negative mood cues from the tendency to engage in exercise in response to eating and body image cues, which themselves may be associated with negative mood. The measure also assesses exercising in response to positive mood cues.
