Does response to treatment differ between anorexia nervosa and atypical anorexia nervosa? Findings from two open series trials.

BACKGROUND: No evidence-based treatments exist for atypical anorexia nervosa (AAN) and little is known about differences in response to treatment between anorexia nervosa (AN) and AAN. The purpose of this paper is to explore treatment outcomes in two pilot trials for those with AN and AAN. METHODS: Study 1 (N = 127) examined treatment outcomes in a digital imaginal exposure trial and Study 2 (N = 34) examined outcomes in a personalized treatment trial. Participants with an active eating disorder (ED) were eligible and those with AN or AAN were included in these analyses. ED symptoms and ED-related fears were assessed at pre-treatment, post-treatment, and one and six-month follow-up. Linear mixed effects models explored treatment outcomes by diagnosis. RESULTS: There were no significant differences in treatment response between diagnoses for most outcome measures. In Study 2, participants with AAN had a significant decrease in global ED symptoms across time, while AN did not. LIMITATIONS: The samples were primarily white and female, limiting the generalizability of the studies. Additionally, due to limited consensus on "significant weight loss," a less conservative definition was used to diagnose AAN which may impact the results. CONCLUSIONS: In general, those with AN and AAN may respond to treatment similarly, with some small differences. Digital exposure therapy may be effective treatments for both AN and AAN, especially for ED-related fears. Personalized treatment may be more effective for those with AAN than those with AN.

Does terminology matter when measuring stigmatizing attitudes about weight? Validation of a brief, modified attitudes toward obese persons scale.

Objective: Commonly used terms like "obese person" have been identified as stigmatizing by those with lived experience. Thus, this study sought to revise a commonly used measure of weight stigmatizing attitudes, the Attitudes Toward Obese Persons (ATOP) scale. Methods: The original terminology in the 20-item ATOP (e.g., "obese") was compared to a modified version using neutral terms (e.g., "higher weight"). Participants (N = 832) were randomized to either receive the original or modified ATOP. Results: There was a statistically significant difference, with a small effect size (d = -0.22), between the scores of participants who received the original ATOP (M = 69.25) and the modified ATOP (M = 72.85), t(414) = -2.27, p = 0.024. Through principal component analysis, the modified ATOP was best used as a brief, 8-item unidimensional measure. In a second sample, confirmatory factor analysis verified the fit of the brief, 8-item factor structure. Conclusions: Findings suggest that a modified, brief version of the ATOP (ATOP-Heigher Weight; ATOP-HW) with neutral language is suitable for assessing negative attitudes about higher-weight people. The ATOP-HW may slightly underestimate weight stigma compared to the original ATOP, or the language in the ATOP may magnify negative attitudes. Further examination of the terminology used in weight stigma measures is needed to determine how to best assess weight stigma without reinforcing stigmatizing attitudes. The present study's findings suggest that the use of neutral terms in measures of anti-fat bias is a promising solution that warrants further investigation.

Eating Disorder Treatment Access in the United States: Perceived Inequities Among Treatment Seekers.

OBJECTIVE: Although eating disorders are associated with high rates of psychological and physical impairments and mortality, only about 20% of individuals with eating disorders receive treatment. No study has comprehensively assessed treatment access for those with these disorders in the United States. The authors examined access to eating disorder treatments and how it might vary among some populations. METHODS: Seekers of treatment for eating disorders (N=1,995) completed an online assessment of clinical demographic and anthropometric characteristics, barriers to eating disorder treatment access, and eating disorder symptomatology. Analyses were conducted to identify treatment access barriers, compare barriers to treatment access across demographic groups, and investigate relationships between barriers to treatment access and eating disorder symptoms. RESULTS: Financial barriers (e.g., lack of insurance coverage) were the most frequently reported barrier to treatment access. Participants with historically underrepresented identities and with a diagnosis of other specified feeding or eating disorder (OSFED) reported more barriers related to financial challenges, geographic location, eating disorder identification, sociocultural factors, and treatment quality compared with those with historically represented identities (e.g., White and cisgender persons). Higher frequencies of reported barriers to treatment access were associated with more severe eating disorder symptoms and poorer illness trajectories. CONCLUSIONS: Financial barriers were the most significant impediment to accessing treatment among individuals seeking eating disorder treatment. Barriers to treatment access disproportionally affected underrepresented groups and those with an OSFED diagnosis.

Traditional versus virtual partial hospital programme for eating disorders: Feasibility and preliminary comparison of effects.

OBJECTIVE: Minimal research has examined teletherapy for group or intensive eating disorder (ED) treatment, particularly partial hospital programme (PHP). This study compared treatment outcomes for individuals treated before and after a pandemic-driven implementation of virtual PHP. METHOD: Patients received care at ED treatment centres using the Renfrew Unified Treatment for Eating Disorders and Comorbidity. Patients treated with virtual PHP were compared to patients treated with traditional PHP. Measures of ED symptomology and behaviours, depressive symptoms, anxiety severity, anxiety sensitivity, experiential avoidance, mindfulness, and body mass index (BMI; reported for anorexia nervosa [AN] patients only) were collected at intake and discharge. Multiple regression analyses were conducted to examine the effect of treatment group on outcomes, controlling for intake score, comorbidity, discharge status, AN diagnosis, and step-down status. RESULTS: Differences in treatment type were only found for binge eating frequency, with those in virtual PHP reporting significantly lower binge eating episodes at discharge than those in traditional PHP. Body mass index showed significantly less improvement in virtual PHP than in traditional PHP. CONCLUSIONS: Preliminary results suggest virtual PHP is feasible and effective, potentially increasing access to evidence-based, intensive ED treatment. However, additional research is needed to establish efficacious support for weight gain among individuals with AN in virtual programs.

Profiles of experienced and internalized weight-based stigma in college students across the weight spectrum: Associations with eating disorder, depression, and anxiety symptoms.

OBJECTIVE: Weight stigma comprises negative attitudes and weight-related stereotypes that result in rejection, discrimination, and prejudice against individuals in larger bodies. Both internalized and experienced weight stigma are associated with negative mental health outcomes, yet it remains unknown how types of stigmatizing experiences (e.g., systemic vs. intraindividual), internalized stigma, and weight status relate, or how profiles of weight stigma differentially impact mental health. METHOD: The current study (N = 1001 undergraduates) used latent profile analysis to identify weight stigma risk profiles and test whether profiles were cross-sectionally associated with eating disorder symptoms, depression, and social appearance anxiety. RESULTS: The best-fitting solution indicated a class high on all facets of weight stigma, a class low on all facets of weight stigma, and three groups with intermediate levels of weight, weight bias internalization, and experienced weight stigma. Gender, but not ethnicity, was associated with class membership. Classes with higher experienced and internalized stigma had higher eating disorder symptoms, depression, and social appearance anxiety. CONCLUSION: Findings support the utility of weight stigma profiles in identifying risk for negative mental health outcomes. These findings can inform initiatives to reduce weight stigma among college students, especially among high-risk groups.

Eating Disorder Screening and Treatment in a Medically Underserved Southern State: Data Collected by a Legislative Eating Disorder Council and Implications for Statewide Assessment.

Healthcare providers play a key role in early identification of eating disorders (EDs), especially in underserved states where ED treatment resources are lacking. Currently, there is little known about ED screening and treatment practices in underserved states. The current study assessed current ED screening and treatment practices among healthcare providers in an underserved state using data collected by a government-formed state ED council. Healthcare providers (N = 242; n = 209 behavioral health providers; n = 33 medical providers) practicing in Kentucky completed a brief, anonymous survey on ED screening and treatment practices, comfort with screening for EDs, and interest in continued education. Over half of healthcare providers indicated screening for EDs, with the majority using a clinical interview. After identification of ED symptoms, providers reported a combination of treating in-house, referring out, or seeking consultation. In bivariate analyses, medical providers were significantly more likely than behavioral health providers to use a screening tool specifically designed for EDs. The majority of medical providers indicated that they received education about EDs and feel knowledgeable about ED screening tools, though most reported infrequent use of these screening tools in their practice. Nearly all behavioral health and medical providers expressed interest in continuing education on ED screening and treatment. These findings indicate a need for, and interest in, education on evidence-based ED screening and treatment resources in underserved states and demonstrate the utility of a state ED council to collect these data to inform future education and treatment strategies.
