“…Major depressive disorder and suicide risk express the highest cooccurrences (52.4% and 40.0%, respectively) [ 5 ]. Post-traumatic stress disorder is reported in up to 17.5%, 20.7%, and 21.5% of patients diagnosed with anorexia nervosa (AN), bulimia nervosa (BN), and binge ED (BED) [ 6 ]. Comorbidity in EDs may have increased given physical inactivity and the accelerated prevalence of depressive, anxiety, and traumatic symptoms in the general population over the course of the COVID-19 outbreak [ 7 – 9 ].…”

“…While Facebook addiction increases the risk for EDs by inducing mood dysfunctions [ 36 ], it is also highly prevalent in affective disorders and anxiety disorders (up to 28.6% and 0.9%) [ 37 ], which frequently cooccur in EDs [ 5 , 6 ]. Longitudinal studies indicate that Facebook addiction in these conditions reduces positive mental health, resulting in increases in depressive symptoms and insomnia—common indicators of poor recovery [ 48 ].…”

Objective Facebook addiction is increasing, giving rise to limited real-life social networks, loneliness, poor work and academic performance, psychopathology, and low well-being. Facebook entails numerous factors that increase the risk for disordered eating attitudes and behaviors (e.g., use time and Facebook activities such as social grooming and photo sharing). This study aimed to evaluate the psychometric properties of the Bergen Facebook Addiction Scale (BFAS) among patients with eating disorders (EDs) given lack of validation of Facebook addiction measures in this population. Methods A cross-sectional study involving 123 inpatient and outpatient women with EDs (Mean age = 27.3, SD = 10.6, range = 14–59 years) used confirmatory factor analysis (CFA), multigroup CFA, structural equation modeling (SEM), Spearman’s rho Spearman’s analysis, McDonald's Omega (ω), Cronbach’s alpha (α), and item-total correlations to examine the structure, invariance, criterion validity, reliability, and discriminant validity of the BFAS. Results Correlating the residuals of items 2, 3, and 5 resulted in an excellent fit of a one-factor structure of the BFAS (χ2(7) = 8.515, p = .289, CFI = .998, TLI = .996, RMSEA = .042, SRMR = .0099). The BFAS was invariant at the configural, metric, and scalar levels across groups of EDs, age, education, and marital status. High values of ω and α (.96) as well as item-total correlations (.851–.929) indicated excellent reliability and high discrimination index of the BFAS. Criterion validity is noted by strong positive correlation with the Six-item Internet Addiction Test (S-IAT, r = .88) and SEM using the S-IAT to predict the BFAS (χ2(49) = 103.701, p = .001, CFI = .975, TLI = .966, RMSEA = .096, SRMR = .0317).. Conclusion The BFAS is a reliable unidimensional measure. Its high discrimination index and invariance across different groups make it useful for detecting Facebook addiction among patients with ED.

“…Past histories of severe adverse life experiences and resultant diagnoses of posttraumatic stress disorder (PTSD) have been frequently associated with eating disorders (EDs) in adults (Brewerton et al., 2020b; Ferrell et al., 2020). However, relatively little is known about the extent to which trauma and PTSD symptoms occur in children and adolescents with EDs, especially those being treated in higher levels of care.…”

Objective Past traumatic events, subsequent posttraumatic stress disorder (PTSD) and related psychiatric comorbidities are commonly associated with eating disorders (EDs) in adults but remain understudied in adolescents. Methods Adolescent participants (mean [SD] age = 15.1 ± 1.5 years, 96.5% female) with EDs entering residential treatment (n = 647) at six sites in the United States completed validated self‐report assessments of ED, PTSD, major depression, anxiety disorders and quality of life. Provisional DSM‐5 PTSD diagnoses (PTSD+) were made via the Childhood Trauma Questionnaire, admission interviews and the PTSD Symptom Checklist for DSM‐5. Results PTSD+ occurred in 35.4% of participants, and those with ED‐PTSD+ had significantly higher scores on all assessments (p ≤ 0.001), including measures of ED psychopathology, major depression, anxiety disorders and quality of life, as well as significantly higher rates of all forms of childhood trauma. Those with PTSD+ also exhibited a significantly higher percent median body mass index for age and sex and a lower propensity toward anorexia nervosa, restricting type. Conclusions Results confirm that adolescent patients in residential treatment with ED‐PTSD+ are more symptomatic and have worse quality of life than their ED counterparts without PTSD. Integrated treatment approaches that effectively address ED‐PTSD+ are greatly needed in ED programs that treat adolescents.

“…Research suggests that EDs and PTSD are highly comorbid and may represent a high-risk group for poor outcomes [ 30 , 31 ]. Data suggest that nearly all individuals with EDs in community samples have experienced trauma [ 27 , 35 ], and between 25 and 40% of individuals with a diagnosed ED meet criteria for PTSD or endorse clinically significant symptoms of PTSD [ 11 , 27 ]. Rates of PTSD are even higher among individuals in ED treatment, particularly in higher levels of care, with one study showing 52% of women hospitalized for an ED reported PTSD or symptoms consistent with PTSD [ 16 ].…”

Integrating evidence-based PTSD treatment into intensive eating disorders treatment: a preliminary investigation

Purpose Given data suggesting common co-occurrence and worse outcomes for individuals with eating disorders (EDs) and post-traumatic stress disorder (PTSD), it is critical to identify integrated treatment approaches for this group of patients. Past work has explored the feasibility and initial efficacy of intervention approaches that draw on evidence-based treatments for both EDs and PTSD; however, this work remains limited in scope. In the current study, we explored the feasibility and naturalistic outcomes of PTSD treatment delivered within the context of intensive ED treatment. Method Participants were 57 adult men and women with DSM-5 EDs and comorbid PTSD who completed a course of either Prolonged Exposure (PE; n = 22) or Cognitive Processing Therapy (CPT; n = 35) (Msessions = 10.40; SD = 5.13) and weekly validated measurements of clinical symptoms while enrolled in ED programming. Results Multi-level models for PTSD symptoms indicated a significant linear effect of time, such that participants demonstrated significant decreases over time in PTSD symptoms, regardless of treatment modality. Conclusion Our preliminary investigation provides support for the feasibility and efficacy of an integrated approach to treating EDs and PTSD. It is critical for future work to undertake randomized tests of this integrated approach using large, heterogeneous samples. Level of evidence Level IV, multiple time series with intervention
