Responses to bright light exposure in individuals with binge-spectrum eating disorders characterized by high dietary restraint and negative affect.

Circadian rhythm disruptions are associated with binge eating, can be causal of negative mood, and may be corrected with bright light exposure. A subtype of individuals with binge-spectrum eating disorders are characterized by combined high dietary restraint and negative affect. These individuals have higher eating disorder psychopathology and poorer treatment response. We aimed to test the targeted effects of morning bright light exposure on individuals with binge-spectrum eating disorders, hypothesizing significant reductions in binge eating for those characterized by high dietary restraint and negative affect. Participants (N = 34 females with binge-eating disorder and bulimia nervosa) used a morning bright light and normal light for 10 consecutive days each, in randomized order. They completed the Change in Eating Disorder Symptoms (CHEDS) scaleat baseline, day 12 (when they switched lamps), and day 22. We conducted moderation analyses, clustering data by person, controlling for order, and examining the effect of light condition on binge eating according to baseline restraint and negative affect. At high levels of combined dietary restraint and negative affect, participants experienced a reduction in binge eating and food preoccupation following exposure to morning bright light. There were no changes in restrictive eating, body preoccupation, body dissatisfaction, or body checking following exposure to morning bright light for these individuals. These findings suggest that morning bright light may be a useful adjunct to empirically supported eating disorder treatments that target binge eating, especially for individuals characterized by the difficult to treat restraint/negative affect subtype. At high levels of combined dietary restraint and negative affect, participants with binge-spectrum eating disorders experienced a reduction in binge eating and food preoccupation following exposure to morning bright light. These findings suggest that morning bright light may be a useful adjunct to empirically supported eating disorder treatments that target binge eating, especially for individuals characterized by the difficult-to-treat restraint/negative affect subtype.

Development of a transdiagnostic digital interactive application for eating disorders: psychometric properties, satisfaction, and perceptions on implementation in clinical practice

BackgroundGiven limited availability of informed treatments for people affected by eating disorders (EDs), there has been increasing interest in developing self-administered, technology-based ED interventions. However, many available interventions are limited to a specific ED diagnosis or assume that participants are ready to change. We developed a digital self-help application (called ASTrA) that was explicitly designed to be transdiagnostic and to help increase motivation for change. The aim of the present study was to describe the development and examine the psychometric properties, user satisfaction and rated potentials for practical use of our application.MethodsThe content of our application was based on concepts derived from self-determination theory, the transtheoretical model of change, and cognitive theory. The application was developed by a multidisciplinary team of clinicians, researchers, staff members and individuals with lived ED experience, each being involved in all steps of the application’s development. We tested validity, reliability, satisfaction and perceived feasibility for clinical implementation in an independent sample of 15 patients with an ED and 13 clinicians specialized in ED treatment. Psychometric properties were evaluated using descriptive statistics, correlations, content validity indices and intraclass coefficients. Differences in satisfaction ratings and perceived potential for clinical implementation of the application between clinicians and patients were examined using Mann–Whitney U tests.ResultsThe digital application showed excellent validity (mean i-CVI: .93, range: .86–.96) and internal reliability (all Cronbach alpha’s > .88). Patients and clinicians both considered the application acceptable, appropriate, and feasible for use in clinical practice.ConclusionsFindings suggest that our transdiagnostic interactive application has excellent psychometric properties. Furthermore, patients and clinicians alike were positive about the possible use of the application in clinical practice. The next step will be to investigate the application's effectiveness as an intervention to promote autonomous motivation and to facilitate remission in people on the waitlist for specialized ED treatment.

Adding executive function training to cognitive behavioral therapy for binge eating disorder: A pilot randomized controlled trial

Evidence-based treatments for binge eating disorder (BED), such as cognitive behavioral therapy (CBT) lead to successful outcomes only about half the time. Individuals with BED often have measurable deficits in executive function (EF) that may challenge adherence to or impact of cognitive behavioral intervention components. The aim of this study was to evaluate the impact of adding EF training to CBT by combining CBT with a compensatory cognitive training approach (EF-CBT). Participants were 32 adults with BED, overweight/obesity, and comorbid anxiety or depression who were randomly assigned to four months of group treatment in either standard CBT or EF-CBT. Outcomes were assessed at baseline, post-treatment, and at 2-month follow-up. Results showed that EF-CBT was feasible and acceptable, comparable to CBT. Both groups significantly decreased loss of control (LOC) days, clinical impairment, and depression at post-treatment and 2-month follow-up; though there were no differences between groups. Neither group significantly reduced anxiety or weight. Exploratory analyses found that participants with lower EF treated with EF-CBT were less likely to have LOC at post-treatment than those with lower EF treated with CBT. Higher self-monitoring rates during treatment were associated with lower LOC at post-treatment and participants with lower EF were more likely to self-monitor in the EF-CBT arm relative to the CBT arm. These findings suggest that EF-CBT is feasible, acceptable and efficacious, although larger scale research is needed. EF-CBT may be particularly suited for individuals with BED who have lower EF.

Eating disorders in transgender and gender diverse people: characteristics, assessment, and management.

This review summarizes recent research on eating disorders among gender minorities, transgender and gender diverse people. The focus is on research published in 2022 and the first half of 2023. Up to 1.2% of young people and 0.3-0.5% of adults identify as transgender, and 2.7-8.4% of young people and 0.3-4.5% of adults report some degree of gender diversity. About 20-50% of transgender and gender diverse people report engaging in disordered eating and >30% screen positive for eating disorder symptoms, and 2-12% have received an eating disorder diagnosis from a health professional. Many transgender and gender diverse people describe eating disorder symptoms as a way of coping with gender dysphoria. They also report high levels of mental and behavioral symptoms, particularly mood and anxiety disorders, suicidal thoughts and behaviors, trauma-related symptoms and disorders, alcohol and substance use, and autism. Gender minorities frequently experience discrimination, victimization, and violence, primarily sexual and physical violence. The minority stress model attributes mental health symptoms to these factors. Promising interventions based on the minority stress model have recently become available, but more research is needed on how to support transgender and gender diverse people with eating disorders. To manage eating disorders in this population, gender-affirming care should be combined with specialist eating disorder treatment. Gender minorities are at high risk for eating disorders. Future studies should assess what is the most appropriate treatment for transgender and gender diverse people with eating disorders.

Pressure From Within: Gay-Community Stress and Body Dissatisfaction Among Sexual-Minority Men

Although intraminority gay-community stress has been theorized to affect sexual-minority men’s body dissatisfaction, this association has not been evaluated quantitatively. Using two samples of sexual-minority men—one sample recruited from a population-based study of U.S. adults ( N = 424; age: M = 54.29 years) and the other a sample meeting diagnostic criteria for depressive, anxiety, or trauma-/stressor-related disorders ( N = 251; age: M = 26.52 years)—in this study, we investigated associations between gay-community stress and body dissatisfaction. In both samples, gay-community stress was significantly associated with sexual-minority men’s greater body dissatisfaction in models that controlled for demographic and minority-stress variables. In terms of specific domains of gay-community stress, perceptions of the gay community’s focus on sex, social status, and social competition were significant correlates of greater body dissatisfaction. Future research can determine the impact of routinely addressing gay-community stress in body image and eating-disorder treatments for this population.

Comparing self-harming intentions underlying eating disordered behaviors and nonsuicidal self-injury: Replication and extension in adolescents.

Eating disorder (ED) behaviors are often characterized as indirect forms of self-harm. However, recent research has found less clear demarcations between direct self-harming behaviors (e.g., nonsuicidal self-injury [NSSI], suicidal behaviors) than previously assumed. The aim of this study was to replicate findings of this prior research on adult populations in adolescents with a history of restrictive eating. A total of 117 adolescents between ages 12-14 were included in the study. Participants reported the presence and frequency of binge eating, compensatory, restrictive eating, and NSSI. Participants also reported thoughts of and intentions to hurt and kill themselves when engaging in each behavior on average. The t-tests and linear effects models were conducted to compare self-harming thoughts and intentions across behaviors. Participants reported at least some intent to hurt themselves physically in the moment and in the long-term when engaging in all ED behaviors and NSSI, and reported engaging in these behaviors while thinking about suicide. Direct self-harming knowledge and intentions were most frequently reported with NSSI and longer-term knowledge and intentions via NSSI and restrictive eating. Additionally, participants reported some suicidal thoughts and intentions across behaviors. This study replicates prior research, suggesting that adolescents engage in ED behaviors and NSSI with non-zero self-harming and suicidal thoughts and intentions. ED behaviors and NSSI may better be explained on a continuum. Implications include the recommendation of safety planning during ED treatment. This study highlights the overlap between eating disorder (ED) behaviors, nonsuicidal self-injury (NSSI), and suicide. Though clear distinctions typically exist for motives of self-harming behavior between ED behaviors (i.e., indirect, in the long run) and NSSI (i.e., direct, in the moment), this research suggests that intentions for self-harming and suicide may exist on a continuum. Clinical ED treatment should consider safety planning as part of routine interventions.

Metacognitive interpersonal therapy-eating disorders versus cognitive behavioral therapy for eating disorders for non-underweight adults with eating disorders: study protocol for a pilot pre-registered randomized controlled trial.

Eating disorders (ED) are serious disorders characterized by an alteration of eating habits and excessive concern about weight and body shapes (Fairburn, 2002), accompanied by significant impairment inequality of life, high mortality rates and serious organic consequences (Jenkins et al., 2011; Treasure et al., 2015; 2020). Although evidence-based psychological therapies for nonunderweight ED presentations such as cognitive behavioral therapy for eating disorders (CBT-ED) are widely available, there is substantial scope for improvements, particularly in terms of efficacy and adherence. One option is to develop interventions to address elements of pathology not fully addressed by existing empirical supported treatments, such as incorporating techniques aimed at addressing interpersonal problems and personality disorder features into existing treatment delivery. We adapted Metacognitive Interpersonal Therapy, a psychological intervention supported by evidence for treating personality disorders and integrated it with existing CBT techniques for eating disorders (MIT-ED). MIT-ED targets aspects of ED that are not included in the transdiagnostic CBT-E model such as poor metacognition, or maladaptive interpersonal schemas. This is a pre-registered (Protocol number: 0000781) pilot randomized clinical trial aimed at assessing acceptability and feasibility of MIT-ED and establishing preliminary evidence of effectiveness for future larger studies. Twenty patients (10 in each arm) will be randomized to 20 sessions of individual psychotherapy, either MIT-ED or CBTE. Repeated follow-ups will be collected up to 24 months. Participants are recruited at a private outpatient clinic for ED treatment. Acceptability will be assessed via session attendance, completion rates and preliminary outcomes. The primary outcome is ED pathology assessed with the Eating Disorder Examination Questionnaire-6. Other ED outcomes assessed will be eating disorder attitudes, clinical impairment and binge eating pathology. Secondary treatment outcomes are anxiety, depression, and global symptomatology. We will also assess emotional awareness, emotion regulation and therapeutic alliance. Based on previous studies of MIT for personality disorders we hypothesize that MIT-ED will be acceptable to patients, evidenced by high treatment adherence and retention. We hypothesize that MIT-ED will be associated with reductions in eating disorder pathology, at least equivalent to CBT-E. Results will be used to inform the study design, sampling, likely effect sizes and choice of outcome measures for future larger trials of MIT-ED in ED samples.

Assessing the feasibility of an intervention for adolescents and parents transitioning out of paediatric eating disorder services: A mixed methods study.

To assess the feasibility of a new intervention designed to support adolescents and parents in the transition from paediatric eating disorder (ED) treatment to adult mental health services. Pre-transition adolescents with EDs, and their parents, were invited to complete up to five transition intervention components over 3months. A mixed methods design was used to assess intervention feasibility, comprised of acceptability and preliminary effectiveness. A single-arm pre-post design was used to collect and analyse quantitative survey and feasibility data. Individual qualitative interviews and written reflections were collected and analysed using content analysis. This study yielded a 33% (10/31) recruitment rate and 68% (13/19) retention rate. On average, participants completed 75% of the expected components in under 3months, with varied completion of each expected intervention component (40%-100%). Participants found the intervention convenient and helpful. Parents reported a significant decrease in guilt (Z=-2.02, p=0.04, d=-0.83). By 1-month post-transition, three adolescents transitioned to interim supports and none started specialist adult treatment. Although this transition intervention did not demonstrate adequate feasibility, its acceptability and effectiveness should be evaluated after an update based on participant feedback. Other solutions to bridge the transition gap for adolescents with EDs should continue to be identified. NCT04888273.

Do People Want the 'New Normal'? A Mixed Method Investigation of Young Person, Parent, and Clinician Experience and Preferences for Eating Disorder Treatment Delivery in the Post-COVID-19 World.

Eating disorder treatment was predominantly provided online during the COVID-19 pandemic, which has continued into the post-pandemic world. This mixed method study explored young person, parent/caregiver, and clinician experiences of child and adolescent eating disorder treatment. In total, 90 participants (25 young people, 49 parents/caregivers, and 16 clinicians) completed online surveys about the experience of online working. Data were compared to similar data collected by the same service earlier in the pandemic. The results show that preferences are largely unchanged since 2020; online treatment is considered helpful and acceptable by all groups. Nevertheless, face-to-face assessment sessions (young people: 52.2%; and parents/caregivers: 68.9%) and final sessions (young people: 82.6%; and parents/caregivers: 82.2%) were preferred compared to online. There was also a preference for early treatment sessions to either be always or mostly face-to-face (young people: 65.2%; and parents/caregivers: 73.3%). The middle and latter parts of treatment were a time when preferences shifted slightly to a more hybrid mode of delivery. Participants reported finding engagement with the therapist (young people: 70.6%; and parents/caregivers: 52.5%) easier during face-to-face treatment. Stepping away from the binary of online or face-to-face, the current data suggest that a hybrid and flexible model is a way forward with current findings providing insights into how to structure this.

A Call to Shift Theoretical Orientation for Eating Disorder Treatment in Social Work: Inside-Out and Outside-In.

A Call to Shift Theoretical Orientation for Eating Disorder Treatment in Social Work: Inside-Out and Outside-In.

Back to the future: Progressing memory research in eating disorders.

Human behaviors, thoughts, and emotions are guided by memories of the past. Thus, there can be little doubt that memory plays a fundamental role in the behaviors (e.g., binging), thoughts (e.g., body-image concerns), and emotions (e.g., guilt) that characterize eating disorders (EDs). Although a growing body of research has begun to investigate the role of memory in EDs, this literature is limited in numerous ways and has yet to be integrated into an overarching framework. In the present article, we provide an operational framework for characterizing different domains of memory, briefly review existing ED memory research within this framework, and highlight crucial gaps in the literature. We distinguish between three domains of memory-episodic, procedural, and working-which differ based on functional attributes and underlying neural systems. Most recent ED memory research has focused on procedural memory broadly defined (e.g., reinforcement learning), and findings within all three memory domains are highly mixed. Further, few studies have attempted to assess these different domains simultaneously, though most behavior is achieved through coordination and competition between memory systems. We, therefore, offer recommendations for how to move ED research forward within each domain of memory and how to study the interactions between memory systems, using illustrative examples from other areas of basic and clinical research. A stronger and more integrated understanding of the mechanisms that connect memory of past experiences to present ED behavior may yield more comprehensive theoretical models of EDs that guide novel treatment approaches. Memories of previous eating-related experiences may contribute to the onset and maintenance of eating disorders (EDs). However, research on the role of memory in EDs is limited, and distinct domains of ED memory research are rarely connected. We, therefore, offer a framework for organizing, progressing, and integrating ED memory research, to provide a better foundation for improving ED treatment and intervention going forward.

Hospitalization patterns for adolescents with eating disorders during COVID-19

PurposeThe purpose of this study was to examine differences in clinical characteristics and hospital length of stay (LOS) for adolescents with eating disorders (EDs) requiring medical stabilization during the pre-COVID-19 and COVID-19 time periods.MethodsMedical record data were abstracted for patients with EDs hospitalized for medical stabilization between 1/1/2019–2/29/2020 (pre-COVID-19) and 3/1/2020–12/31/2021 (during COVID-19). Patient demographics, clinical characteristics and LOS were compared between COVID-19 eras. Patients were categorized as boarding if they remained hospitalized ≥ 1 day after medical stabilization. Multivariate negative binomial linear regression models were performed to determine incidence rate ratios (IRR) and 95% confidence intervals (95% CI) for factors related to increased LOS.ResultsOf the 467 admissions during this study, 120 were pre-COVID-19 and 347 were during COVID-19. Monthly admissions for EDs were higher during COVID-19 versus pre-COVID-19 (15.8 vs. 8.6, p = 0.001). On multivariate analysis, factors associated with increased LOS included admission during COVID-19 (IRR 1.27, 95% CI 1.15–1.40), p = 0.001), boarding (IRR 1.77, 95% CI 1.63–1.93, p = 0.001), public insurance (IRR 1.12, 95% CI 1.01–1.23, p = 0.032), nasogastric tube usage (IRR 1.62, 95% CI 1.48–1.76, p = 0.001), heart rate < 40 beats per minute (IRR 1.21, 95% CI 1.11–1.33, p = 0.001) and abnormal electrocardiogram (IRR 1.25, 95% CI 1.14–1.37, p = 0.001).ConclusionIn addition to clinical factors, we found that admission during COVID-19, boarding, and public insurance were associated with increased LOS among patients with EDs. There is a need for greater availability of ED treatment centers to care for patients with EDs after medical stabilization.

Positive communication workshops: are they useful for treatment programmes for anorexia nervosa?

Social isolation, loneliness and difficulties in relationships are often described as a core feature of eating disorders. Based on the experimental research, we have designed one-off workshops for patients in inpatients and day care services and evaluated its acceptability and effectiveness using feedback questionnaires. This naturalistic project is an evaluation of multiple positive communication workshops. Forty-one participants completed workshop questionnaires, which were provided immediately at the beginning and end of the workshop, including feedback on these one-off groups. The workshops consisted of educational and experiential components. The questionnaire outcomes were evaluated by independent researchers. All participants were female adults with a mean age of 33 (12.2) and a diagnosis of Anorexia Nervosa (AN; either restrictive or binge-purge subtype). Post-workshop questionnaires showed large effect sizes in the improvement of understanding the importance and confidence in using positive communication strategies. Addressing social communication difficulties in eating disorder treatment programmes adds valuable dimensions to these symptom-based treatments in both inpatient settings and day services, and may provide broader benefits in overall social functioning in patients with AN. Brief one-off workshops targeting social functioning for patients with eating disorders might be useful complementary input for treatment programmes.

An intervention mapping adaptation framework to develop a self-help intervention for athletes with eating disorder symptoms.

This research forum describes the use of the intervention mapping for adaptation (IMA) framework to develop and evaluate a novel intervention for athletes with mild eating disorder (ED) symptoms. The six IMA steps were followed. In step 1 (needs assessment), we conducted a systematic review of athlete ED interventions and held interviews/focus groups with athletes and sports professionals to inform intervention format and delivery. In step 2 (intervention search), needs assessment information guided the search for an evidence-based intervention suitable for adaptation to athletes. In steps 3 and 4 (intervention development), the identified intervention was adapted and feedback sought from athletes and sport professionals. In steps 5 and 6 (implementation and evaluation), a feasibility study was conducted with athletes (n = 35; females: n = 27; Mage = 27.1). The review highlighted poor evidence for the acceptability and relative efficacy of existing interventions, which were all delivered face-to-face in groups. Interview/focus group data suggested a need for more accessible intervention formats (e.g., self-help). One non-athlete self-help intervention was determined suitable for adaptation to athletes, and adaptations were made. Initial feedback suggested the adapted intervention was relevant within sport settings. The feasibility study revealed that the intervention (MOPED-A: Motivational and Psycho-Educational Self-Help Programme for Athletes with Mild Eating Disorder Symptoms) can be feasibly implemented, is acceptable to athletes and shows potential for reducing ED symptoms. IMA is a useful framework for developing participant-centered and evidence-based interventions. The findings and approach taken provide a framework for other researchers and clinicians in developing similar interventions in the ED domain. The novel self-help intervention described in this article was developed using intervention mapping and provides promise as a tool for reducing eating disorder symptoms in athletes. We describe how adopting and systematically following a health intervention development approach, such as intervention mapping, can ensure that eating disorder interventions are participant-centered, contextually relevant, and evidence-based, which in turn could help to maximize their reach and effectiveness.

Experiences of a virtual day program for adolescents with eating disorders: a qualitative analysis of benefits and barriers

BackgroundThroughout the COVID-19 pandemic, there was a detrimental impact to the symptoms and treatment of eating disorders, causing an increase in medical admissions and visits. Day treatment programs (DTPs), often used to bridge the gap between inpatient and outpatient treatment, were converted to online formats. This study aims to explore the impact of the transition to virtual DTPs on eating disorder treatment from the perspective of adolescents, their caregivers, and program staff.MethodsTwelve participants (3 adolescents, 4 caregivers, 5 healthcare providers) in a virtual day treatment program were interviewed using a semi-structured interview guide. Interviews were transcribed and managed with qualitative software NVivo 11.0. Conventional analysis was used to inductively identify pertinent themes related to patient, caregiver, and healthcare staff perceptions and experiences of the virtual day treatment. Summative content analysis provided counts of the barriers and benefits of virtual day treatment as identified by participants.ResultsThe majority of participants (10/12) had exposure to both virtual and in person settings, most participants (11/12) felt in-person day programs would be superior to virtual programs. Common limitations of the virtual format were feelings of isolation, less support from healthcare providers, parental burnout, and increased disordered eating. Common benefits were increased accessibility, parental involvement, improved communication with healthcare staff, and the ability for participants to be in their home environment and eat home food. Suggestions for improvement included designing a hybrid model of day treatment, increased family involvement, extending the day program to include dinners with family, and screening for patient appropriateness for the virtual setting.ConclusionThis qualitative study suggests that there are many barriers to effective implementation of virtual day programs. However, the virtual DTP program offers increased accessibility to patients during a period of a health pandemic and to patients in rural/remote areas with limited treatment options. Suggestions provided by participants in this study, such as increased family involvement, frequency of in person check-ins and increased number of meals supported by the program, may help to improve outcomes in virtual day treatment programs.

Trends in the effect of COVID-19 on consultations for persons with clinical and subclinical eating disorders

BackgroundThe coronavirus disease 2019 (COVID-19) pandemic has increased the risk of individuals developing eating disorders and has exacerbated existing eating disorders. This observational study investigated the impact of the COVID-19 pandemic on patients with clinical and subclinical eating disorders.MethodsThis study was conducted over a period of four years: two years before and after the onset of the COVID-19 pandemic in Japan. We recorded the number and types of consultations provided by the Eating Disorder Treatment and Support Center coordinator. For subgroup analysis, data were classified by age, body mass index, and source of consultation, including patients, families, and personnel. The Seasonal Decomposition of Time Series by Loess was used for time series analysis.ResultsThe total number of consultations increased after the start of the pandemic and peaked around the beginning of 2022, before subsequently falling despite the increase in the number of COVID-19 infections. A similar trend was observed in patients aged 10–29 years. The study period coincided with social isolation and school/college/university closures.ConclusionsThe number of eating disorder consultations increased after the start of the pandemic. Although COVID-19 infections persisted, the pandemic’s impact was transient.

Being a mother with anorexia: A phenomenological study of seeking and receiving professional support for white heterosexual women in the UK

AbstractMothers are currently under‐represented in the literature on anorexia, including research on treatment, with most research focussed on female adolescents. This raises questions about how adult women and particularly those who are mothers, experience eating disorder treatment. This study provides a phenomenological exploration of lived experiences of seeking and receiving professional help and interactions with health professionals for six white heterosexual mothers who experienced anorexia while raising their children. Four themes are reported that capture the women's diverse experiences of seeking and receiving support for anorexia: (1) conflict between mothering and seeking help; (2) experiences of feeling blamed, poorly treated or misunderstood by health professionals; (3) positive experiences of seeking and receiving support; and (4) the importance of ongoing support. The women's experiences suggest that healthcare professionals should adopt a more holistic approach that acknowledges the subjective reality of the client (including their mother status) when working with mothers experiencing anorexia.

Causal discovery analysis: A promising tool in advancing precision medicine for eating disorders.

Precision medicine (i.e., individually tailored treatments) represents an optimal goal for treating complex psychiatric disorders, including eating disorders. Within the eating disorders field, most treatment development efforts have been limited in their ability to identify individual-level models of eating disorder psychopathology and to develop and apply an individually tailored treatment for a given individual's personalized model of psychopathology. In addition, research is still needed to identify causal relationships within a given individual's model of eating disorder psychopathology. Addressing this limitation of the current state of precision medicine-related research in the field will allow us to progress toward advancing research and practice for eating disorders treatment. We present a novel set of analytic tools, causal discovery analysis (CDA) methods, which can facilitate increasingly fine-grained, person-specific models of causal relations among cognitive, behavioral, and affective symptoms. CDA can advance the identification of an individual's causal model that maintains that individuals' eating disorder psychopathology. In the current article, we (1) introduce CDA methods as a set of promising analytic tools for developing precision medicine methods for eating disorders including the potential strengths and weaknesses of CDA, (2) provide recommendations for future studies utilizing this approach, and (3) outline the potential clinical implications of using CDA to generate personalized models of eating disorder psychopathology. CDA provides a novel statistical approach for identifying causal relationships among variables of interest for a given individual. Person-specific causal models may offer a promising approach to individualized treatment planning and inform future personalized treatment development efforts for eating disorders.

Fathers in the spotlight: parental burden and the effectiveness of a parental skills training for anorexia nervosa in mother–father dyads

PurposeResearch on the engagement of fathers in the treatment of childhood psychiatric disorders is scarce. This study aims to investigate differences between mothers and fathers of adolescents with anorexia nervosa regarding parental burden and effectiveness of a parental skills training.MethodsNinety-one mother–father dyads caring for a child with anorexia nervosa participated in an 8-week parental skills training and completed a set of questionnaires assessing parental psychopathology, eating disorder related burden, caregiver skills and expressed emotion at baseline and post-intervention.ResultsFathers showed lower levels of general psychological distress, depression, anxiety and eating disorder related burden as well as lower emotional overinvolvement compared to mothers. The skills training was effective in reducing parental psychopathology, eating disorder-related burden and emotional overinvolvement as well as in increasing caregiver skills with no differences between mothers and fathers. However, session adherence and the willingness to practice skills between the sessions were slightly lower in fathers.ConclusionsThese findings show that fathers are a great resource for the child’s eating disorder treatment as they may counterbalance maternal emotional overinvolvement and over-protection. Furthermore, this is the first study demonstrating that fathers can profit from a parental skills training for anorexia nervosa in a similar way as mothers.Level IIIEvidence obtained from well-designed cohort or case–control analytic studies.
