Title: Realizing the untapped promise of single‐session interventions for eating disorders
Abstract Objective

Multilevel treatment barriers prevent up to 80% of individuals experiencing eating disorders (EDs) from accessing care. This treatment gap creates a critical need to identify interventions that are accessible, easily completable, and optimized for effectiveness by targeting core mechanisms linked to ED onset and maintenance. We propose single‐session interventions (SSIs) as a promising path toward catalyzing innovation in the development of accessible, effective ED interventions. SSIs are structured programs that intentionally involve one encounter with a program or provider; they may serve as stand‐alone or adjunctive clinical supports. All SSIs are built to acknowledge that any session might be someone's last—and that any single session can nonetheless yield meaningful clinical benefit.

Method

We define SSIs, summarize research supporting their utility for ED symptoms and other mental health problems, and recommend future directions for work in this domain.

Results

Single‐session interventions may hold promise to reduce some ED symptoms and risk factors, including restrictive eating and negative body image. Steps toward realizing this promise include (1) testing whether existing evidence‐based SSIs (e.g., for depression) can also reduce EDs, risk factors, and symptoms; (2) developing novel SSIs that target modifiable ED risk factors and symptoms largely unaddressed by SSIs, such as purging and binge eating; (3) studying diverse implementation pathways; (4) capitalizing on SSIs' transdiagnostic utility to broaden funding opportunities; and (5) educating ED researchers and clinicians about SSIs.

Discussion

Understanding the strengths and limits of mechanism‐targeted SSIs for ED‐related problems could be a low‐risk, high‐reward avenue toward reducing EDs at scale.

Public Significance

Most individuals experiencing EDs never access any form of treatment, creating an urgent need to identify ED interventions built to overcome barriers to engaging with care. This Forum article introduces SSIs as a promising path to rapidly developing and testing accessible, evidence‐based ED supports; supplementing existing ED treatment models; and reducing the individual, familial, and societal burdens of EDs at scale.

  1. Abstract Objective

    The current study tested whether people with and without eating disorders (EDs) varied in their implicit attitudes toward ED‐relevant stimuli. Additionally, the study tested whether implicit evaluations of ED‐relevant stimuli predicted ED symptoms and behaviors over a 4‐week interval.

    Method

    Participants were people without EDs (N =85) and people seeking treatment for EDs (N =92). All participants completed self‐report questionnaires and a version of the affect misattribution procedure (AMP) at baseline. The AMP indexed implicit evaluations of average body stimuli, eating stimuli, and ED‐symptom stimuli. Participants with EDs completed weekly follow‐up measures of ED symptoms and behaviors for 4 weeks.

    Results

    Contrary to predictions, the anorexia nervosa (AN) group did not differ from the no ED group on implicit attitudes toward ED‐symptom stimuli, and the bulimia nervosa (BN) group had less positive implicit attitudes toward ED‐symptom stimuli relative to the no ED group. In line with predictions, people with AN and BN had more negative implicit attitudes toward average body and eating stimuli relative to the no ED group. In addition, among the ED group more negative implicit attitudes toward eating stimuli predicted ED symptoms and behaviors 4 weeks later, over and above baseline ED symptoms and behaviors.

    Discussion

    Taken together, implicit evaluations of eating stimuli differentiated people with AN and BN from people without EDs and longitudinally predicted ED symptoms and behaviors. Interventions that increase implicit liking of eating‐related stimuli may reduce ED behaviors.

  2. Abstract Objective

    Many individuals diagnosed with an eating disorder (ED) have been exposed to traumatic events, and some of these individuals are diagnosed with posttraumatic stress disorder (PTSD). Although theorized by researchers and clinicians, it is unclear whether traumatic event exposure or PTSD interferes with outcomes from ED treatment. The objective of the current study was to systematically review the literature on traumatic events and/or PTSD as either predictors or moderators of psychological treatment outcomes in EDs.

    Method

    A PRISMA search was conducted to identify studies that assessed the longitudinal association between traumatic events or PTSD and ED outcomes. Eighteen articles met the inclusion criteria for review.

    Results

    Results indicated that traumatic event exposure was associated with greater ED treatment dropout, but individuals with a traumatic event history benefited from treatment similarly to their unexposed peers. Findings also indicated that traumatic events may be associated with greater symptom relapse posttreatment.

    Discussion

    Given the limited number of studies examining PTSD, results are considered very tentative; however, similar to studies comparing trauma‐exposed and nontrauma‐exposed participants, individuals with PTSD may have similar treatment gains compared to individuals without PTSD, but individuals with PTSD may experience greater symptom relapse posttreatment. Future researchers are encouraged to examine whether trauma‐informed care or integrated treatment for EDs and PTSD mitigates dropout from treatment and improves symptom remission outcomes. Furthermore, researchers are encouraged to examine how the developmental timing of traumatic events, self‐perceived impact of trauma, and cumulative trauma exposure may be associated with differential ED treatment outcomes.

    Public Significance

    Eating disorders (EDs), trauma, and posttraumatic stress disorder (PTSD) often co‐occur. Individuals with traumatic event exposure and/or PTSD demonstrate greater ED symptoms; it is unclear whether these individuals benefit similarly in ED treatment to their peers. The current study found that individuals with traumatic event exposure are more likely to drop out of treatment but benefit from treatment with similar symptom remission. Traumatic history was associated with greater relapse posttreatment.

  3. Abstract Background In clinical research, there has been a call to move beyond individual psychosocial factors towards identifying cultural and social factors that inform mental health. Similar calls have been made in the eating disorders (ED) field underscoring the need to understand larger sociocultural influences on EDs. Discrimination is a social stressor that may influence mental health in similar ways to traumatic or adverse childhood experiences (ACEs). Given the high rates of EDs and discrimination among marginalized groups, it is vital to understand the role of discrimination and ACEs as predictors of ED symptoms in these populations. The aim of this study is to examine how perceived discrimination predicts ED pathology when statistically adjusting for gender, race, and ACEs. Methods The diverse study sample consisted of 331 undergraduate students from a longitudinal cohort study (ages 18–24; 66% female; 35% White/non-Hispanic). Participants completed measures of everyday discrimination, ACEs, and ED pathology. Results Following adjustment for multiple statistical comparisons, the frequency of daily discrimination predicted all ED symptoms above and beyond history of ACEs. In follow-up analyses, number of reasons for discrimination predicted cognitive restraint and purging. Differences in ED symptomatology were found based on the reason for discrimination, gender, and race. Specifically, those who experienced weight discrimination endorsed higher scores on all ED symptoms, and those experiencing gender discrimination endorsed higher body dissatisfaction, cognitive restraint, and restriction. People of color endorsed higher restriction, while female participants endorsed higher scores on all ED symptom with the exception of cognitive restraint. Conclusion Discrimination is a salient risk factor for ED symptoms even when accounting for individuals’ history of ACEs. Future research should utilize an intersectional approach to examine how perceived discrimination affects ED pathology over time. (Word count: 234).

  4. Abstract Background

    Most research on socioeconomic status (SES) and eating disorders (EDs) has focused on young White women. Consequently, little is known regarding how SES may relate to EDs/disordered eating in older adults, men, or people with different racial identities. We examined whether associations between SES and EDs/disordered eating differed across age, sex, and racial identity in a large, population‐based sample spanning early‐to‐later adulthood.

    Methods

    Analyses included 2797 women and 2781 men ages 18–65 (Mage = 37.41, SD = 7.38) from the population‐based Michigan State University Twin Registry. We first examined associations between SES and dimensional ED symptoms, binge eating (BE), and self‐reported ED diagnoses across age and sex in the full sample. We then examined the impact of racial identity on associations by conducting within‐ and between‐group analyses among Black and White participants.

    Results

    In the full sample, lower SES was associated with significantly greater odds of BE and lifetime EDs in men, but not women, across adulthood. The association between lower SES and greater BE risk was stronger for Black men than for White men, though significant in both groups. Conversely, Black women showed apositiveassociation between SES and dimensional ED symptoms that significantly differed from effects for Black men and White women.

    Conclusions

    Associations between socioeconomic disadvantage and EDs/disordered eating may be particularly robust for men in adulthood, especially men with a marginalized racial identity. Oppositely, Black women may encounter social pressures and minority stress in higher SES environments that could contribute to somewhat heightened ED risk.

    Public Significance

    Little is known regarding how associations between socioeconomic status (SES) and eating disorders (EDs) may differ across age/sex or racial identity. We found lower SES was associated with greater odds of a lifetime ED or binge eating in men only, with a particularly strong association between lower SES and binge eating for Black men. Results highlight the importance of examining how SES‐ED associations may differ across other aspects of identity.

    Background

    Posttraumatic stress disorder (PTSD) is a serious public health concern. However, individuals with PTSD often do not have access to adequate treatment. A conversational agent (CA) can help to bridge the treatment gap by providing interactive and timely interventions at scale. Toward this goal, we have developed PTSDialogue—a CA to support the self-management of individuals living with PTSD. PTSDialogue is designed to be highly interactive (eg, brief questions, ability to specify preferences, and quick turn-taking) and supports social presence to promote user engagement and sustain adherence. It includes a range of support features, including psychoeducation, assessment tools, and several symptom management tools.

    Objective

    This paper focuses on the preliminary evaluation of PTSDialogue from clinical experts. Given that PTSDialogue focuses on a vulnerable population, it is critical to establish its usability and acceptance with clinical experts before deployment. Expert feedback is also important to ensure user safety and effective risk management in CAs aiming to support individuals living with PTSD.

    Methods

    We conducted remote, one-on-one, semistructured interviews with clinical experts (N=10) to gather insight into the use of CAs. All participants have completed their doctoral degrees and have prior experience in PTSD care. The web-based PTSDialogue prototype was then shared with the participant so that they could interact with different functionalities and features. We encouraged them to “think aloud” as they interacted with the prototype. Participants also shared their screens throughout the interaction session. A semistructured interview script was also used to gather insights and feedback from the participants. The sample size is consistent with that of prior works. We analyzed interview data using a qualitative interpretivist approach resulting in a bottom-up thematic analysis.

    Results

    Our data establish the feasibility and acceptance of PTSDialogue, a supportive tool for individuals with PTSD. Most participants agreed that PTSDialogue could be useful for supporting self-management of individuals with PTSD. We have also assessed how features, functionalities, and interactions in PTSDialogue can support different self-management needs and strategies for this population. These data were then used to identify design requirements and guidelines for a CA aiming to support individuals with PTSD. Experts specifically noted the importance of empathetic and tailored CA interactions for effective PTSD self-management. They also suggested steps to ensure safe and engaging interactions with PTSDialogue.

    Conclusions

    Based on interviews with experts, we have provided design recommendations for future CAs aiming to support vulnerable populations. The study suggests that well-designed CAs have the potential to reshape effective intervention delivery and help address the treatment gap in mental health.
