Not niche: eating disorders as an example in the dangers of overspecialisation.

Labelling specific psychiatric concerns as 'niche' topics relegated to specialty journals obstructs high-quality research and clinical care for these issues. Despite their severity, eating disorders are under-represented in high-impact journals, underfunded, and under-addressed in psychiatric training. We provide recommendations to stimulate broad knowledge dissemination for under-acknowledged, yet severe, psychiatric disorders.

Executive functioning and treatment outcome among adolescents undergoing cognitive-behavioral therapy for binge-eating disorder.

BACKGROUND: Cognitive-behavioral therapy (CBT) is an evidence-supported treatment for adolescents with binge-eating disorder (BED). Executive dysfunctions, which are associated with binge eating and elevated body weight in youth, may undermine CBT outcomes by making it difficult for youth to engage with or adhere to treatment, including recalling and/or implementing intervention strategies in real-world contexts. METHODS: We assessed 73 adolescents [82.2% female; Mage = 15.0 ± 2.5 year; M baseline standardized body mass index (zBMI) = 1.9 ± 1.0 kg/m2] with BED at baseline, posttreatment, 6-, 12-, and 24-month follow-up. Linear mixed models examined the effects of baseline executive functioning (EF) on loss of control (LOC) eating and weight change following CBT. Linear and logistic regressions probed associations between EF, attendance, and attrition. RESULTS: More impulsive decision-making, as reflected in higher baseline scores on the Iowa Gambling Task, predicted better attendance (ß = .07; p = .019) and more frequent LOC eating following treatment (ß = .12; p = .017). Lower cognitive flexibility, as reflected in lower baseline T-scores on the Comprehensive Trail Making Test complex sequencing index, predicted higher zBMI following treatment (ß = -.03; p = .003). Inhibition, concentration, attention, and parent-reported EF behavior symptoms were not associated with outcome, attendance, or attrition. CONCLUSIONS: More impulsive decision-making and lower cognitive flexibility were associated with suboptimal response to CBT for BED, although findings should be interpreted with caution in light of the sample size and waitlist control design. Future research should examine whether strengthening EF could improve eating and weight outcomes among adolescents with BED who have lower pre-treatment EF.

Addressing Barriers to Career Development Awards for Early Career Women in Pediatric Psychology.

OBJECTIVE: To provide person and system-level recommendations for supporting early career women in the field of pediatric psychology in writing and submitting National Institutes of Health (NIH) Career Development Award (K award) applications. Recommendations are provided in the context of common barriers, with a focus on practical solutions. METHODS: Publicly available NIH reporter data were compiled to examine rates of funding for Society of Pediatric Psychology (SPP) members. Barriers that women face when initiating programs of research are described and applied to the field of pediatric psychology. RESULTS: Of current SPP members, 3.9% (n = 50) have ever received an NIH K award. Approximately 88.5% of SPP members identify as women, including 89.0% of SPP K award recipients. A table of person- and systems-level recommendations is provided to offer strategies for mentees, mentors/sponsors, institutions, and national organizations to address the barriers discussed. CONCLUSIONS: By addressing gender-specific barriers to submitting K award applications, we hope to increase the number of women K awardees and support the scientific advancement of pediatric psychology.

Sleep, Affect, and Emotion Reactivity in First-Year College Students: A Daily Diary Study.

BACKGROUND: Sleep is an important factor in well-being, especially during the transition to college when academic and social commitments increase. Identifying factors that contribute to poor sleep (including short duration and increased variability in duration) can support development of interventions. Affect and emotion reactivity are factors that could contribute to sleep, and have not been studied in relation to sleep variables among first-year college students during their adjustment to the college environment. This adjustment might be difficult for some students, and therefore elicit affect fluctuations that contribute to poor sleep. Alternatively, sleep could contribute to daily affect. The present daily diary study examined bidirectional relations between daily sleep and affect, as well as between emotion reactivity and sleep (duration and variability) and affect (daily and overall variability) in first-year college students. METHOD: First-year college students (n = 244; 86.1% female) completed a baseline survey including measures of emotion reactivity and anxiety and depressive symptoms, followed by 7 days of a once-per-day diary, reporting on their affect and sleep duration. RESULTS: On days when individuals reported increased sleep duration, they also tended to experience greater positive affect the following day (p = .01). Those who experienced high levels of emotion reactivity also experienced more negative affect (p < .001) and negative affect variability (p < .001). CONCLUSION: Emotion reactivity might identify college students who experience more negative affect and are possibly at risk to develop mental health disorders. The importance of sleep health should continue to be emphasized to students as they transition to college.

When eating disorder attitudes and cognitions persist after weight restoration: An exploratory examination of non-cognitive responders to family-based treatment for adolescent anorexia nervosa.

OBJECTIVE: Family-based treatment (FBT) is a well-established intervention for adolescent anorexia nervosa (AN). Although FBT is efficacious in promoting weight gain and improvements in psychological symptoms, for some adolescents, cognitive/attitudinal recovery lags behind weight gain. This study conducted an exploratory post hoc analysis of outcomes of adolescents who achieved weight gain by the end of FBT but continued to experience elevated psychological symptoms post-treatment. METHODS: Data were drawn from two randomised controlled trials (RCTs) testing two forms of FBT (conjoint/whole family and parent-focussed). Descriptive statistics and generalised estimating equations were used to examine differences in treatment outcomes between non-cognitive responders (NCRs) (those who regained weight but continued to experience psychological symptoms) and full responders (FRs) (those who achieved both weight and cognitive restoration by the end of treatment) (n = 80; 83.7% female, Agemean [SD] = 14.66 [1.73]). RESULTS: By 12 months post-treatment, there were no differences in weight between NCRs and FRs. However, NCRs had a slower trajectory of weight gain than FRs and continued to have elevated levels of psychological symptoms throughout the follow-up period. CONCLUSIONS: A subset of adolescents appear to continue to experience clinically significant levels of eating pathology up to 12 months after FBT even when weight restoration is achieved.

Associations between emotion reactivity and eating disorder symptoms in a transdiagnostic treatment-seeking sample.

OBJECTIVE: Individuals with eating disorders (EDs) demonstrate difficulties with emotion regulation, and these difficulties have been associated with severity and maintenance of ED symptoms. Although emotion reactivity (i.e., the strength and duration of emotional experiences) is distinct from emotion regulation, few studies have examined emotion reactivity in the context of EDs. The purpose of the current study was to examine longitudinal associations between emotion reactivity and ED symptoms and impairment in individuals with EDs. METHOD: Individuals seeking outpatient ED treatment (N = 265) completed questionnaires assessing ED symptoms and severity, emotion reactivity, and emotion regulation difficulties at treatment intake and bi-monthly during treatment. RESULTS: Individuals with anorexia nervosa or binge eating or purging presentations had higher emotion reactivity scores than a non-ED comparison group. Controlling for age, diagnosis, and emotion regulation difficulties, emotion reactivity was positively associated with ED severity, ED-related impairment, and loss of control eating severity. Moreover, emotion reactivity, but not emotion regulation difficulties, was associated with change in ED symptoms during treatment. DISCUSSION: Findings support that emotion reactivity may differ based on ED presentations and may be an important correlate of ED symptom severity. PUBLIC SIGNIFICANCE: Emotion reactivity refers to the strength and duration of an emotional experience. This study found that higher emotion reactivity was related to greater eating disorder symptom severity and eating disorder-related impairment. It may be beneficial to consider the role of emotion reactivity in conceptualizations of eating disorders, particularly those characterized by binge eating or purging.

Reporting racial and ethnic diversity in eating disorder research over the past 20 years.

OBJECTIVE: Recent public awareness of racial and ethnic disparities has again brought to light issues of diversity, equity, and inclusion in the eating disorders field. However, empirical information on racial and ethnic representation in eating disorders research is limited, making it difficult to understand where improvements are needed. METHOD: This study reviewed all studies including human participants published in the International Journal of Eating Disorders in 2000, 2010, and 2020. Differences in likelihood of reporting race and ethnicity were calculated based on study year, location, and diagnostic categories. RESULTS: Out of 377 manuscripts, 45.2% reported information on the race and ethnicity of study participants. Studies conducted in the United States were more likely to report (128/173), and those conducted in Europe were less likely to report (5/61) on race and ethnicity than those conducted outside of those regions. Rates of reporting increased from 2000 to 2020. White participants made up approximately 70% of the samples that reported race and ethnicity data. Hispanic participants made up approximately 10% of samples reporting race and ethnicity. Participants from all other races and ethnicities made up less than 5% each. DISCUSSION: Although rates of reporting race and ethnicity increased over time, most participants were White. Rates of reporting also differed by the geographical region, which may reflect variability in how information on race and ethnicity is collected across countries. More attention toward capturing the cultural background of research participants and more inclusivity in research are needed in the eating disorders field.

Implementation and outcomes of home-based treatments for adolescents with anorexia nervosa: Study protocol for a pilot effectiveness-implementation trial.

OBJECTIVE: Although family-based treatment (FBT) is considered a first-line treatment for adolescent anorexia nervosa (AN), it is underutilized in community settings and is unavailable to many families for a multitude of practical reasons (e.g., costs of treatment, transportation constraints). Adapting FBT interventions for delivery in home-based and community-based settings may reduce pragmatic barriers to treatment uptake and engagement. METHODS: This pilot effectiveness-implementation trial will assess outcomes, implementation, and mechanisms of FBT adapted for the home setting (FBT-HB), delivered in the context of community-based behavioral health agencies. Adolescents with AN-spectrum disorders (n = 50) and their caregivers will be randomly assigned to either FBT-HB or home-based treatment as usual (TAU; integrated family therapy approach). Caregivers and adolescents will provide data on weight, eating, and putative treatment mechanisms, including caregiver self-efficacy and adolescent eating-related and weight-related distress. Implementation constructs of feasibility, acceptability, and appropriateness will be measured among providers and participating families. HYPOTHESES: We expect that FBT-HB will be feasible, acceptable, and appropriate, and will outperform TAU in terms of improvements in adolescent weight and eating-related psychopathology. We further expect that caregiver self-efficacy and adolescent eating-related and weight-related distress, but not general distress, will show greater improvements in FBT-HB relative to TAU and will be associated with better adolescent weight and eating outcomes in FBT-HB. POTENTIAL IMPLICATIONS: The proposed study has clear potential to advance scientific and clinical understanding of the real-world effectiveness of FBT for AN, including whether adapting it for the home setting improves its accessibility and effects on treatment outcome.

Accountability in promoting representation of historically marginalized racial and ethnic populations in the eating disorders field: A call to action.

Promoting representation of historically marginalized racial and ethnic populations in the eating disorders (EDs) field among professionals and the populations studied and served has long been discussed, with limited progress. This may be due to a reinforcing feedback loop in which individuals from dominant cultures conduct research and deliver treatment, participate in research, and receive diagnoses and treatment. This insularity maintains underrepresentation: EDs in historically marginalized populations are understudied, undetected, and undertreated. An Early Career Investigators Workshop generated recommendations for change that were not inherently novel but made apparent that accountability is missing. This paper serves as a call to action to spearhead a paradigm shift from equality to equity in the ED field. We provide a theoretical framework, suggest ways to disrupt the feedback loop, and summarize actionable steps to increase accountability in ED leadership and research toward enhancing racial/ethnic justice, equity, diversity, and inclusion (JEDI). These actionable steps are outlined in the service of challenging our field to reflect the diversity of our global community. We must develop and implement measurable metrics to assess our progress toward increasing diversity of underrepresented racial/ethnic groups and to address JEDI issues in our providers, patients, and research participants.

Delicious and difficult to resist?: Inhibitory control differs in young women after exposure to food and non-food commercials.

Unhealthy food marketing, a ubiquitous food stimulus, may impact response inhibition, making it more difficult to maintain healthy eating behaviors. Individuals with disordered eating may be particularly susceptible to altered inhibition responses to food stimuli, making them more vulnerable to unhealthy food marketing, which could perpetuate their disordered eating behaviors. The present study examined response inhibition following exposure to food commercials in young women who reported either high levels of disordered eating (HEC) or low/no disordered eating (LEC) (N = 27; age: M = 19.28, SD = 1.01) by measuring event related potentials (ERPs) during a stop-signal task embedded with food stimuli. Results indicated that participants had significantly higher accuracy on stop trials displaying unhealthy food stimuli than trials displaying healthy food stimuli after viewing non-food commercials but displayed no difference after viewing food commercials. LEC individuals displayed a smaller N200/P300 amplitude in response to food stimuli on the stop-signal task after watching food commercials as compared to non-food commercials, but this difference did not exist for HEC individuals. Results indicate that unhealthy food commercials may impact behavioral and electrophysiological correlates of response inhibition evoked by food stimuli in young women, and individuals with disordered eating might actually be less responsive to food marketing than those without disordered eating.

The moderating role of sleep duration on momentary relations between negative affect and loss-of-control eating in children and adolescents.

OBJECTIVE: Loss-of-control (LOC) eating is associated with eating disorders and obesity, and thus it is imperative to understand its momentary risk factors in order to improve intervention efforts. Negative affect has been proposed as a momentary risk factor for LOC eating, but the evidence for its effects in children and adolescents is mixed. Short sleep duration (which is very common in youth), may be one variable that moderates the relation between negative affect and subsequent LOC eating. As such, we aimed to examine the moderating role of within-person sleep duration on the momentary relations between negative affect and subsequent LOC eating. METHOD: We recruited children (N = 30) with overweight/obesity ages 8-14, who completed a 2-week ecological momentary assessment protocol assessing negative affect and LOC eating several times per day, while also wearing a sleep actigraphy device and completing sleep diaries. RESULTS: Consistent with hypotheses, within-person sleep duration moderated the next-day momentary relation between within-person negative affect and LOC eating, such that shorter sleep duration strengthened the positive relation between negative affect and loss-of-control eating. CONCLUSIONS: Results suggest that, in children and adolescents, fluctuations in sleep duration may influence susceptibility to losing control over eating after experiencing negative affect. Future research should further investigate other metrics of sleep disturbance as they relate to emotion regulation and LOC eating. Such research will set the stage for augmenting paediatric interventions to better target maintenance factors for LOC eating.

Variability of Sleep and Relations to Body Weight Among First-Year College Students.

BACKGROUND: Existing research suggests that greater sleep variability may increase risk for weight gain. College often marks a transition to a less consistent daily schedule, which may adversely impact sleep routines and further increase risk for weight gain. The current study is among the first to explore relations between nighttime sleep variability and daytime sleep (napping) and body weight among first-year college students. METHODS: Using daily diary methods, first-year college students (N = 307; 84.7% female) self-reported their sleep for seven days. Several indices were created to capture sleep variability for reported bedtime, wake time, and sleep duration, including weekday versus weekend differences (WvW), day to day differences (D2D), and overall standard deviation (SD). Napping was also assessed. Based on body mass index (BMI), individuals were categorized as underweight, healthy weight, overweight, and obese. RESULTS: Across indices, students' sleep varied over an hour on average across the week. Hierarchical regressions revealed that greater differences in wake time D2D, wake time SD, and sleep duration WvW were all associated with higher BMI, after accounting for gender, depressive symptoms, and sleep duration. Longer napping was also associated with higher BMI, using the same covariates. Finally, greater sleep variability was reported by overweight and obese than healthy weight individuals. CONCLUSION: These findings suggest that sleep variability, particularly wake times and napping may be important modifiable sleep behaviors to investigate in future studies. More longitudinal research is needed to explore relations between multiple facets of sleep variability and weight gain, including possible mechanisms.

Momentary associations between positive affect dimensions and dysregulated eating during puberty in a diverse sample of youth with overweight/obesity.

OBJECTIVE: The link between dysregulated positive affect and binge-eating behavior in youth with obesity is poorly understood. In addition, it is unclear how putative associations differ across developmental periods of rapid biological and emotional change, such as puberty, and in racial and ethnic minority youth, who are more likely to be overweight but are underrepresented in the literature. METHOD: This study used a 2-week ecological momentary assessment protocol to examine independent and interactive effects of positive affect intensity/instability, and pubertal stage on two components of binge-eating behavior, loss of control eating (LOCE), and overeating. RESULTS: Participants were 38 youth with overweight/obesity (ages 8-14 years; 78% African American/Hispanic). Positive affect instability was calculated using probability of acute change (PAC), representing the likelihood of extreme affective changes, and mean squared successive difference (MSSD), representing the average change in affect over successive recordings. There were no main effects of positive affect intensity on LOCE or overeating, but positive affect instability was negatively associated with overeating severity using both MSSD (p = .005) and PAC metrics (p = .001). However, moderation analyses including interactions with pubertal status revealed more extreme changes in positive affect (i.e., higher PAC) were related to greater overeating (p = .001) and LOCE severity (p = .043) in mid-late pubertal youth but not in pre-early pubertal youth. DISCUSSION: Pubertal status may influence the association between disruptions in positive affect and dysregulated eating in youth, and positive affect instability may be important to consider in order to understand the emotional correlates of binge eating in youth with overweight/obesity.

Executive function and dietary intake in youth: A systematic review of the literature.

Despite increasing evidence that childhood obesity may be related to impairments in executive function, the evidence supporting the relation between executive function (EF) and dietary intake, a key factor linked to obesity, is mixed. Although research from the obesity literature often interprets EF as a factor that may influence dietary intake, there is also evidence that dietary intake may influence EF. Drawing on a developmental perspective, this systematic review examines the literature on the link between executive function (i.e., inhibition, working memory, and cognitive flexibility) and dietary intake in youth through the inclusion of cross-sectional, longitudinal, and intervention studies aimed at altering either dietary intake or EF as a way to influence the other. In total, 5650 studies were screened for eligibility. Twenty-six studies met inclusion criteria and were included in the review. Results indicated that the relation between executive function and dietary intake is equivocal. Although there is some support for a cross-sectional relation between executive function and dietary intake, the lack of longitudinal studies makes it difficult to make conclusions about directionality. Findings from intervention studies do not support the effectiveness of short-term manipulations on dietary intake to change subsequent EF, and few intervention studies exist that explicitly aim to "train" EF to change subsequent dietary intake. Furthermore, the wide variety of measures used to assess EF and dietary intake, and the lack of consideration of the role that weight status may play in the relation between EF and dietary intake, make overall interpretation of the literature more difficult. In sum, there is a need for more prospective research examining a variety of ages, domains of EF, and weight statuses, taking into account developmental factors.

Chronic Stress and Food Insecurity: Examining Key Environmental Family Factors Related to Body Mass Index Among Low-Income Mexican-Origin Youth.

Low-income children of Mexican immigrants are at high risk for obesity. Drawing on a sample of 104 Mexican American children (Mage = 8.39 years; 61% female), this longitudinal study considered relations between food insecurity and chronic stress (ie, parent report and hair cortisol measurement) on body mass index (BMI) and examined whether stress moderated associations between food insecurity and BMI. Analyses revealed that undocumented status was associated with food insecurity and chronic stress but not when accounting for poverty. Food insecurity was only associated with higher BMI for children with the highest hair cortisol. Results suggest that chronic stress may impact body weight among food-insecure children.

Affect, reward, and punishment in anorexia nervosa: a narrative overview.

INTRODUCTION: Anorexia nervosa (AN) is a serious psychiatric disorder that is difficult to treat and often follows a protracted course. A number of theoretical models have been proposed for the etiology and maintenance of AN. Two domains that have received substantial attention in the literature on AN are affect and reward/punishment processes. However, despite an overlap in the nature and implications of these processes, studies of AN addressing these constructs have typically investigated them independently. PURPOSE: The purpose of this narrative review is to integrate the literature on the role of affect, reward, and punishment in AN. METHOD: We provide a focused narrative overview of the literature relating to the affect, reward, and punishment in AN via a synthesis of recent reviews and meta-analyses. RESULTS: We first describe several prominent affect and reward/punishment-based conceptualizations of AN, followed by a brief overview of the existing empirical literature in these domains. CONCLUSION: We provide a critical discussion of the disparate nature of these literatures in AN, including associated limitations. We then conclude with an extensive discussion of directions for future research that integrate the study of affect and reward/punishment processes in AN. LEVEL OF EVIDENCE: Level V, narrative review.

A qualitative assessment of provider-perceived barriers to implementing family-based treatment for anorexia nervosa in low-income community settings.

BACKGROUND: Family-based treatment (FBT) is a front-line empirically supported intervention for adolescent anorexia nervosa, but it is often inaccessible to families from lower income backgrounds, as it is most typically available in specialty research and private practice settings. In preparation for a pilot trial of FBT delivered in the home setting, this study qualitatively examined provider perceptions of implementing FBT in lower-income communities. METHODS: Eating disorder clinicians working in community clinics (therapists, medical doctors, dietitians, and social workers; n = 9) were interviewed about their experiences using FBT. Interview transcripts were analyzed both deductively, using an approach consistent with applied thematic analysis, and inductively, using the Replicating Effective Programs implementation framework, to examine barriers to FBT implementation. RESULTS: Prevailing themes included concern about the time and resources required of caregivers to participate in FBT, which may not be feasible for those who work full time, have other caregiving demands, and/or lack family support. Psychosocial problems outside of the eating disorder, such as food insecurity, other untreated mental health concerns (in themselves or other family members), or externalizing behaviors on the part of the adolescent, were also discussed as barriers, and participants noted that the lack of cohesive treatment teams in the community make it difficult to ensure continuity of care. CONCLUSION: Findings from this qualitative study indicate the need to address systemic socioeconomic barriers to improve the efficacy of implementation of FBT in the community and to understand how provider perceptions of these barriers influence their uptake of FBT.

This study looks at reasons why providers think that family-based treatment for adolescent anorexia nervosa (FBT) is difficult to implement in community settings serving families from lower-income backgrounds. When interviewed, participants expressed concerned that FBT requires a lot of time and resources from families and that problems beyond the eating disorder (like having other mental health conditions or not having enough money to make ends meet) get in the way of treatment.

A qualitative analysis of adolescents' perspectives on peer and influencer alcohol-related posts on social media.

INTRODUCTION: Adolescent exposure to alcohol-related content on social media is common and associated with alcohol use and perceived norms; however, little is known about how exposure differs by the source of the content (e.g., peer or 'influencer'). The purpose of this study was to utilise qualitative methods to compare adolescent perspectives on peer- versus influencer-generated alcohol content on social media. METHODS: Nine virtual semi-structured focus groups were conducted with adolescents (aged 15-19 years), following a general script aimed at ascertaining adolescent comparative perspectives on peer and influencer alcohol-related media content and the contexts in which it occurs. RESULTS: Five main themes emerged: (i) although both influencers and peers post predominantly positively-valenced alcohol content online, adolescents perceived some differences between these posts; (ii) adolescents perceived their peers to be more cautious and strategic when posting about alcohol than influencers are; (iii) the decision to engage with peer or influencer alcohol-related posts is influenced by a number of factors; (iv) both peer and influencer posts were perceived to send the message that drinking is acceptable, normal or cool; and (v) adolescents believed they are more likely to be influenced by peers' alcohol posts than influencers' alcohol posts, with some exceptions. DISCUSSION AND CONCLUSIONS: Future studies should aim to further understand the unique attributes and circumstances in which exposure to peer and influencer alcohol-related posts impact adolescent alcohol-related cognitions and behaviours. This knowledge will inform prevention and intervention efforts, such as media literacy training and media-specific parenting practices.

Adolescents' perceptions of alcohol portrayals in the media and their impact on cognitions and behaviors.

OBJECTIVE: Exposure to alcohol in the media is pervasive and may influence adolescents' perceptions and use of alcohol. The purpose of this study was to better understand how adolescents perceive alcohol-related content in both entertainment and social media, with a focus on the valence of portrayals (i.e., positive, negative) and impacts on cognitions and behaviors. METHOD: Participants were 40 high school students (60% female). Nine focus groups were conducted via videoconferencing, stratified by grade (9th/10th, 11th/12th) and gender. Transcripts were analyzed via template-style thematic analyses to identify themes. RESULTS: Six themes were developed, including (a) some portrayals of alcohol may increase likelihood of using alcohol, (b) some portrayals of alcohol in the media can discourage drinking, (c) sometimes truly negative consequences of alcohol are portrayed positively or downplayed, (d) media portrayals of alcohol are perceived to be based in reality but are at times exaggerated, (e) adolescent and adult alcohol use is portrayed differently in entertainment media, and (f) the extent to which adolescents are influenced by the media may depend on their preexisting attitudes, beliefs, and education. CONCLUSIONS: Adolescents have awareness of media portrayals of alcohol, both positive and negative, and their associated impacts. Findings highlight the need for much more work to understand the conditions under which, and for whom, exposure to different types of positive portrayals of alcohol in the media translate into positive expectancies about alcohol or drinking motives. Such work may ultimately inform intervention targets to reduce early initiation and/or risky drinking among adolescents. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Adapting family-based treatment for adolescent anorexia nervosa delivered in the home: A novel approach for improving access to care and generalizability of skill acquisition.

BACKGROUND: Anorexia nervosa (AN) is a serious mental illness associated with high rates of morbidity and mortality. Family-based treatment (FBT) is a well-established treatment for adolescent AN, yet it is underutilized in community settings and is unavailable to many families, particularly those from lower income and racial and ethnic minority backgrounds. Furthermore, some families do not respond optimally to FBT, possibly because of challenges translating skills acquired in office-based treatment settings to naturalistic settings. Home-based treatment could reduce barriers to access and enhance generalization of newly learned treatment skills. Home-based models demonstrate initial feasibility, acceptability, and efficacy for adolescent AN, however, FBT principles have yet to be applied as a stand-alone intervention in a home-based level of care. This paper describes the rationale for and process of adapting FBT principles/interventions to improve fit within a home-based model delivered in the context of community mental health, and discusses potential strengths and opportunities associated with this approach. RESULTS: Adaptations were made through consultation with collaborating community agencies and were guided by the complex interventions framework. The primary modifications included: (1) altered dose; (2) multiple family meals; (3) additional support for meal preparation and supervision; (4) clinician attendance at medical appointments; (5) cultural adaptation; and (6) introduction of distress tolerance and emotion regulation skills. CONCLUSIONS: Implementing FBT in the home may present one promising and novel approach to enhance engagement and treatment outcomes for adolescents with restrictive eating disorders, particularly those who are underserved, but evaluation of efficacy/effectiveness is needed.
