Although several assessments have been developed to diagnose or measure avoidant/restrictive food intake disorder (ARFID) symptoms, few studies validated these tools in nonclinical and adult samples. This study explored the validity of two self- parent/guardian-report ARFID screening measures identifying adults children who may within a large community sample. Fifty participants (divided into groups: 25 parents/guardians children) were selected from Genes Environment study, which enrolled...
ABSTRACT Objective Self‐report measures of ARFID symptoms (e.g., Nine‐Item Avoidant/Restrictive Food Intake Disorder Screen [NIAS]) are used to assess symptom differences between groups. Measurement invariance techniques clarify if groups interpret a measure similarly, providing foundation for examining group differences. Considering age and reporter status parent vs. self‐report), we investigated measurement the NIAS in (1) self‐reporting adults adolescents; (2) reports on children (3)...
The cognitive-behavioral theory of eating disorders (EDs) proposes that shape and weight overvaluation are the core ED psychopathology. Core symptoms can be statistically identified using network analysis. Existing studies support psychopathology, yet no have estimated AN psychopathology concerns exist about replicability analysis findings. current study symptom networks among people with anorexia nervosa (AN) bulimia (BN) a combined group BN.Participants were girls women (n = 604) BN 477)...
This study examined whether clinical characteristics among patients presenting to residential eating disorder (ED) treatment differed according patients’ trauma history and current PTSD diagnostic status. Participants (699 girls women) completed surveys at onset. One-way analysis of covariance (ANCOVA) tests assessed cross-sectional differences between three groups patients: those reporting no (No Trauma, n = 185), with but without (Trauma, 263), (PTSD, 251). Relative the No Trauma group,...
Abstract Objective Anxiety is thought to influence the development and maintenance of eating disorders (EDs). However, little known about how, specifically, anxiety influences ED symptoms vice versa. Network analysis identifies how within across are interconnected. In a network, central nodes (i.e., symptoms) have strongest relations other maintain psychopathology. Bridge in one diagnostic cluster that strongly connected another explain comorbidity. We identified bridge network trait...
Dialectical Behavior Therapy (DBT) has long been successfully applied to such behaviors as nonsuicidal self-injury (NSSI) and more recently, bulimic behaviors. However, it is less clear how patients experiencing these comorbid symptoms may benefit from this treatment modality. Self-criticism, defined a highly negative attitude towards the self, implicated in both EDs NSSI amenable DBT; thus, further examination of construct be beneficial informing DBT approaches. research only examined...
Abstract Objective Residential treatment for severe eating disorders (EDs) is associated with primarily positive outcomes. However, less known about the moderators of response. Comorbid post‐traumatic stress disorder (PTSD) diagnosis increased ED symptom severity. This study investigated whether PTSD moderated outcomes transdiagnostic, residential based upon Unified Protocol. Method Female patients ( N = 1055) in completed a clinical interview to assess and self‐reported ED, depression,...
Implementation of evidence-based practices (EBPs) in intensive treatment settings poses a major challenge the field psychology. This is particularly true for eating disorder (ED) treatment, where multidisciplinary care provided to severe and complex patient population; almost no data exist concerning best these settings. We summarize research on EBP implementation science organized by existing frameworks illustrate how may be applied using case example. describe recent successful EBPs...
Abstract Objective Minimal research has examined teletherapy for group or intensive eating disorder (ED) treatment, particularly partial hospital programme (PHP). This study compared treatment outcomes individuals treated before and after a pandemic‐driven implementation of virtual PHP. Method Patients received care at ED centres using the Renfrew Unified Treatment Eating Disorders Comorbidity. with PHP were to patients traditional Measures symptomology behaviours, depressive symptoms,...
Abstract Introduction Muscle Dysmorphia (MD) is a severe subtype of body dysmorphic disorder (BDD) that shares symptomatic overlap with eating disorders. Although associations between disorders/BDD and suicidality are well documented, research has rarely examined MD symptoms suicidality, which concerning given associated additional suicide risk factors compared these Further, existing have yet to establish temporal ordering for relationships. Therefore, the current study investigated...
Objective Previous research shows that interoceptive deficits are associated with harmful behaviors such as nonsuicidal self‐injury (NSSI), eating disorder pathology, and suicide attempts. The present study replicates extends this area of by examining the association between suicidality in a military sample. Method In Study 1, respondents to an online survey ( N = 134) answered self‐report questionnaires related deficits. 2 consisted secondary data analysis 3,764 service members who had...
Abstract Objective Despite the high rates of suicidality in body dysmorphic disorder and eating disorders (EDs), research on a related disorder, muscle dysmorphia (MD), is essentially nonexistent. Thus, this study tested relations between suicidal thoughts behaviors MD ED symptoms an online male community sample. Method A total 464 males ( M age = 40.3; 85% Caucasian) recruited from Amazon's Mechanical Turk completed measures that evaluated symptoms, current ideation, past suicide attempts....
Celebrity suicides that are reported heavily in the media may increase risk for others' suicidal behavior. This study examined whether Internet search volumes suicide-related terms changed after three celebrity suicide deaths (Robin Williams, Chester Bennington, and Alexander McQueen) celebrities who died by means other than (David Bowie, Azzedine Alaia, Paul Walker). Suicide included suicide, how to commit depression, hanging, prevention. Observed United States were collected from Google...
Cross-sectional research demonstrates significant correlations between eating disorders (EDs) and suicidal thoughts behaviors. Although suicide ideation (SI) is a risk factor for behavior, longitudinal investigating SI among EDs limited. Thus, the aim of this study was to offer insight into dynamic relationship by if these variables predicted one another at weekly time points.Autoregressive cross-lagged modeling used test bidirectional relationships ED symptoms an patient sample (n = 92)....
Abstract Background The Avoidant Restrictive Food Intake Disorder – Genes and Environment (ARFID-GEN) study is a of genetic environmental factors that contribute to risk for developing ARFID in children adults. Methods A total 3,000 adults with from the United States will be included. Parents/guardians their (ages 7 17) 18 +) complete comprehensive online consent, parent verification child assent (when applicable), phenotyping. Enrolled participants submit saliva sample genotyping....

Abstract Objective Although disordered eating is robustly associated with suicidal thoughts, it not well understood why these conditions relate to each other. Emotion dysregulation a shared risk factor for and thoughts. Individuals dysregulated emotions struggle select appropriate strategies modulate the they use might explain some of variances. Thus, we examined whether emotion regulation mediated relationship between ideation. Method Adult participants ( N = 230) completed questionnaires...
