A brief examination of treatment outcomes in higher levels of care for individuals with eating disorders across age groups

OBJECTIVE

Although eating disorders (EDs) occur throughout the lifespan, little research has been conducted with midlife/older adults, particularly those in higher levels of care (HLOC). The current study examined outcomes among 2009 patients with EDs receiving HLOC treatment at a large multisite facility between January 2020 and June 2022, across different age groups (ages <18, 18-25, 26-39 and ≥40). It was hypothesised that patients aged 40+ would exhibit less improvement on measures of ED psychopathology and depression than other age groups.

METHOD

Participants completed the eating disorder examination-questionnaire (EDE-Q) and the patient health questionnaire-9 (PHQ-9) at admission and discharge.

RESULTS

Changes for all outcomes from admission to discharge were statistically significant at p < 0.001 across all age groups. Changes in the EDE-Q Restraint subscale were significantly less in patients ages 26-39 than in patients ages 18-25 (p < 0.01). Changes in PHQ-9 were significantly greater in patients ages 40+ than patients ages 18-25 (p = 0.03).

CONCLUSIONS

Contrary to hypotheses, patients ages 40+ did not show worse outcomes than younger patients, and showed greater improvements in depression than young adults. The therapeutic needs of midlife/older adults with EDs may be favourably met by a HLOC regimen as described in this study.

Characterising use of recovery record among a large, transdiagnostic sample of adults with eating disorders across higher levels of care

OBJECTIVE

Smartphone applications (i.e., apps) designed to target mental health symptoms have received increasing public and empirical attention, including in eating disorder|eating disorders (EDs) treatment. While some data have begun to characterise app users in non-controlled settings, there is limited information on use of apps in higher levels of care (e.g., partial hospitalisation or residential treatment programs) for EDs.

METHOD

This study aimed to explore metrics of use while in treatment for a commonly used ED-focused mobile app (Recovery Record) among individuals enroled in intensive outpatient, partial hospitalisation, residential, or inpatient treatments (N = 2042).

RESULTS

Results indicated that older individuals and participants with binge eating disorder demonstrated more frequent app engagement compared to younger participants and other ED diagnoses, respectively. Individuals entering at intensive outpatient and partial hospitalisation levels of care, as well as those with routine discharges engaged more frequently with RR compared to individuals entering in inpatient or residential treatment, and those with non-routine discharges.

CONCLUSIONS

Our data provide initial descriptions of how RR may be used within higher levels of care for adults with EDs. Further work is needed to establish the benefit of these apps in clinical settings for EDs over and above standard treatment, better characterise for whom these apps provide benefit, and identify how best to tailor the experience to promote engagement across the full spectrum of ED patients.

Weight gain and eating disorder symptoms among individuals with atypical anorexia nervosa

OBJECTIVE

The purpose of this study was to examine the association between weight gain and eating disorder (ED) symptoms among adults receiving treatment for atypical anorexia nervosa (AAN), to determine whether those who had a higher percent of expected body weight (%EBW) at discharge exhibited lower ED symptoms than those who gained less weight, and to compare this group to a matched sample of patients with anorexia nervosa (AN).

METHOD

Participants were 96 adults receiving treatment at an ED treatment facility between December 2020 and May 2023. The Eating Disorder Examination-Questionnaire (EDE-Q) was completed at admission and discharge, and %EBW was obtained at admission and discharge.

RESULTS

All EDE-Q subscale scores improved from admission to discharge for patients with AAN and patients with AN. Neither %EBW at discharge nor weight gain were associated with EDE-Q subscale scores for those with AAN. For patients with AN, %EBW at discharge and weight gain were associated with EDE-Q Restraint at discharge.

CONCLUSIONS

Weight restoring to a higher level and gaining more weight were not associated with EDE-Q scores at discharge for AAN. Further research is needed to determine how weight restoration using intensive treatment settings affects remission and recovery in patients with AAN.

"Terminal anorexia nervosa" may not be terminal: An empirical evaluation

Gaudiani et al. (2022) presented terminal anorexia nervosa (T-AN) as a potential new specifier to the anorexia nervosa (AN) diagnosis, with criteria including (a) AN diagnosis, (b) age > 30 years, (c) previously participated in high-quality care, and (d) the clear, consistent determination by a patient with decision-making capacity that additional treatment would be futile, knowing death will result. This study's purpose was to empirically examine a subgroup of participants with AN who met the first three criteria of T-AN-and a smaller subset who also met a proxy index of the fourth criterion involving death (TD-AN)-and compare them to an adult "not terminal" anorexia nervosa (NT-AN) group and to a "not terminal" subset 30 years of age or older (NTO-AN). Patients at U.S. eating disorder treatment facilities (N = 782; T-AN: n = 51, TD-AN: n = 16, NT-AN: n = 731, NTO-AN: n = 133), all of whom met criteria for a current Diagnostic and Statistical Manual of Mental Disorders, 5th Edition diagnosis of AN, were compared regarding admission, discharge, and changes from admission to discharge on physiological indices (i.e., white blood cell counts, albumin levels, aspartate aminotransferase levels, and body mass index), as well as self-report measures (i.e., eating disorder, depression, anxiety, and obsessive-compulsive symptoms). In contrast to the tight syndromal symptom interconnections of, and inevitable spiral toward death expected for, a terminal diagnosis, results suggest substantial variability within the T-AN group and TD-AN subset, and an overall trend of improvement across physiological and self-report measures. This study thus provides some empirical evidence against the specification of the T-AN diagnosis. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

An examination of adults with atypical anorexia nervosa at admission to treatment at higher levels of care: An attempt to increase diagnostic clarity

OBJECTIVE

Anorexia nervosa (AN) is a serious illness with a high mortality rate and multiple physiological complications. The vague definition of atypical AN allows for subjective interpretation. This retrospective study aimed to focus future research on the operational definition of atypical AN by examining four factors associated with atypical AN at admission to higher level of care treatment.

METHODS

Adults with atypical AN (n = 69) were examined within sample analyses among four groups: (1) >10% versus ≤10% weight loss; (2) weight loss within the previous 3 months versus >3 months; (3) engaging in purging behaviors versus absence of purging behaviors; and (4) endorsing versus not endorsing significant cognitive aspects of AN.

RESULTS

Patients with atypical AN endorsed elevated ED cognitions on the Eating Disorder Examination-Questionnaire and depressive symptoms; a lack of association was found between weight loss severity and weight loss time frame with depressive symptoms, eating concern, and restraint. Purging behavior was associated with a higher expected body weight percentage (%EBW) and dietary restraint, while greater AN cognitions were associated with a higher EBW and weight loss percentage. Few patients demonstrated bradycardia, hypophosphatemia, or amenorrhea.

DISCUSSION

This study demonstrated the severity of ED cognitions and depressive symptoms in this atypical AN sample and provided directions for future studies in the nosology of atypical AN. It may be important to distinguish between individuals with atypical AN who are purging and those who are not. Atypical AN was associated with a low frequency of physiological disturbances.

PUBLIC SIGNIFICANCE

This study provides further clarification regarding the operational definition of atypical AN; currently, a constellation of symptoms under Other Specified Feeding or Eating Disorders. This study was consistent with previous research in reporting severe eating disorder cognitions in adults with atypical AN, and noted the potential importance of distinguishing a purging distinction. A minority of patients in this study had physiological impairments.

Eating disorder virtual intensive outpatient program: patient satisfaction according to age group

The COVID-19 pandemic has required a shift to telehealth services. However, not all patients are similarly satisfied with this shift, with some studies finding that midlife and older adults are less comfortable with telehealth. The current study examined patient satisfaction with a virtual intensive outpatient program (VIOP) for eating disorders (EDs) among 305 adults (ages 18-25, ages 26-39, and ages 40+), and compared adult satisfaction to satisfaction among children/adolescents (n = 33) receiving VIOP treatment between August 2020 and March 2022 from a large ED treatment facility. It was hypothesized that adults aged 40+ would report lower satisfaction than younger age groups. Patients completed several questions regarding satisfaction with treatment upon discharge, including a question about likelihood of recommending the program, which was used to calculate a Net Promoter Score (NPS). The NPS was 33.3 for children/adolescents, 33.3 for 18-25 year-olds, 57.7 for 26-39 year-olds, and 30.9 for the 40+ year age group. NPS of 31-50 = quality services; 51-70 = excellent customer experiences. Satisfaction was high, with no statistically significant differences between age groups after Bonferroni correction. The current study adds to the limited literature on the treatment experiences of midlife adults with EDs.

Expressed emotion and early treatment response in family-based treatment for adolescent anorexia nervosa

This study examined the effect of pre-treatment levels of parental expressed emotion (EE) on early treatment response for adolescent anorexia nervosa (AN). Data were collected from 121 adolescents, ages 12-18, who met DSM-IV criteria for AN excluding the amenorrhea criterion, and their parents. Participants were randomized to family-based treatment (FBT) or adolescent-focused therapy (AFT). To examine the effects of different thresholds of EE, we used two different levels of EE in analyses. Results demonstrated that adolescents who had at least one parent with elevated EE indicated by a lower threshold (i.e. even mild levels) at baseline were less likely to achieve an early treatment response, suggesting that EE might interfere with treatment success from the start of treatment. When high EE was defined by a higher threshold, these effects were no longer significant, regardless of treatment type (FBT or AFT). These findings suggest that adolescents with AN may be more sensitive to EE than other mental illnesses, such that lower thresholds of EE impact the speed with which they are able to reduce symptoms and gain weight in treatment. It may be necessary to target parental EE prior to or early in treatment or pivot to parent-focused treatment to change the trajectory of treatment response. Future research is needed to explore ways parental EE can be reduced.

An open trial for adults in a residential program for binge eating spectrum disorders

The current study assessed treatment outcome for 99 adult admissions to a residential program specifically designed for binge eating spectrum disorders (BESD). Participants completed self-report measures at admission, discharge, and 12-month follow-up and were asked to complete blood draws at admission and follow-up. Primary outcomes were eating behaviors; secondary outcomes included comorbid symptoms and physiological variables. Eating behaviors improved significantly from admission to follow-up, as did most comorbid symptoms and quality of life, despite no change in body mass index. Some variables displayed a curvilinear relationship, with some worsening of symptoms from discharge to follow-up, although scores at follow-up remained well below admission values. Participation in the treatment program was associated with reduced problematic eating and comorbid symptoms and increased quality of life up to one year after discharge. Findings from this study may encourage the development of similar residential treatment programs for BESD for those who have not responded to outpatient care or mixed milieu settings, and may prompt randomized studies testing similar treatments versus usual care.

A descriptive study of treatment-seeking adults with avoidant/restrictive food intake disorder at residential and inpatient levels of care

Most research on avoidant/restrictive food intake disorder (ARFID) has been with children and adolescents, while the limited research on adults with ARFID has been in the domain of outpatient treatment. This descriptive study sought to explore psychological characteristics (N = 45; measured with self-report questionnaires) and physiological characteristics (N = 66; e.g. vital signs, bloodwork) at admission for 66 adults with ARFID seeking residential and inpatient levels of care. While adults with ARFID presented with significant food restriction as well as mild depressive symptoms, high anxiety symptoms, and impaired quality of life, patients presented with mostly normal physiology, except for low bone density, and trivial abnormalities in serum creatinine and hepatic enzymes. Patients in this sample were most likely to endorse fear of aversive consequences, especially those for whom ARFID symptoms had first arisen in adulthood. These results note the psychological impairment and relative physiological normalcy of treatment-seeking adults with ARFID at the outset of residential and inpatient treatment, identifying future treatment and outcome research priorities in this understudied population.

Eating Disorder Examination-Questionnaire: Norms for Adults in Higher Levels of Care

Establishing normative data for questionnaires is essential for the accurate interpretation of scores, given that these norms can vary according to different subpopulations and treatment contexts. The purpose of this study was to establish norms for the Eating Disorder Examination-Questionnaire (EDE-Q) among adults receiving higher levels of care (HLOCs) for the treatment of eating disorders. Participants were 2,283 people receiving treatment at the inpatient, residential, partial hospitalization, or intensive outpatient levels of care. The EDE-Q was completed at admission. Patients with anorexia nervosa-restricting subtype (AN-R) had the lowest EDE-Q Global scores when compared with all other eating disorder diagnoses. When compared with intensive outpatient care, only those in residential treatment had higher EDE-Q Global scores. This study is among the first to describe norms for the EDE-Q in a large sample of adults receiving various HLOCs. Programs utilizing the EDE-Q to assess treatment outcomes can use these findings to aid people in interpreting their scores.

Involuntary treatment: A qualitative study from the perspectives of individuals with anorexia nervosa

OBJECTIVE

Involuntary treatment for anorexia nervosa (AN) is sometimes necessary and lifesaving but can be experienced negatively by some individuals. The purpose of this qualitative study was to better understand participants' perceptions about their experience with involuntary treatment for AN.

METHOD

Thirty adult participants, who had been treated involuntarily for AN in the past, completed self-report measures and qualitative interviews. Interview transcripts were coded using thematic analysis.

RESULTS

Three themes were identified: (1) mixed perceptions about involuntary treatment, (2) the impact of involuntary treatment on external factors, including relationships, education, and employment, and (3) lessons learned from the experience. Participants who endorsed a positive shift in perspective regarding the need for involuntary treatment also reported favorable changes in their eating disorder recovery, whereas individuals whose perspective about their involuntary treatment remained negative, showed no changes in their recovery post-treatment.

CONCLUSIONS

Involuntary treatment for AN was recognized, in retrospect, as being beneficial by individuals with AN who were doing well, but individuals who continued to struggle with their eating disorder reported negative consequences.

Empirical Investigation of Different Factor Structures for the Eating Disorder Examination-Questionnaire in Adult Women With Anorexia Nervosa

The Eating Disorder Examination-Questionnaire (EDE-Q) is a widely used self-report measure of eating pathology. Despite widespread use, investigations of its factor structure have proved inconclusive and rarely supported the "original" interpretation. The current study evaluates several proposed factor solutions of the EDE-Q using latent variable analysis in a sample of adult women with anorexia nervosa (AN). A total of 804 patients from a specialist treatment center in the United States participated in the study. Confirmatory factor analysis was conducted on 22 EDE-Q items assessing attitudinal features of eating pathology. Findings suggested that three full-item versions (none of which was the "original" interpretation) fit the data adequately, with a brief, seven-item version showing excellent fit. The study is one of the first to examine this within a sample of women with AN and provides an empirical foundation for how best to use the EDE-Q among clinical and research participants with AN. Findings suggest that the "original" factor structure lacks structural validity in women with AN. Its use should generally be discouraged, and future work on screening and treatment outcomes might consider the EDE-Q7.

Psychometric properties of the Parent Eating Disorder Examination Questionnaire

OBJECTIVE

To examine the psychometric properties of the Parent Eating Disorder Examination Questionnaire (PEDE-Q), developed to improve eating disorder (ED) assessment among youth by including parents as informants.

METHODS

A multi-site, transdiagnostic sample of 355 adolescents with EDs completed the Eating Disorder Examination Questionnaire (EDE-Q) and their parents completed the PEDE-Q.

RESULTS

The internal consistencies of the PEDE-Q subscales were on par with established EDE-Q ranges (.73 to .90), both when examined using the original four-factor EDE-Q subscales and the seven-item, three-factor subscales of the brief EDE-Q. Statistically significant medium- to large-sized correlations and poor to moderate levels of agreement were found between the corresponding EDE-Q and PEDE-Q subscales. Receiver-operator characteristic (ROC) curves showed that the PEDE-Q had a statistically significant area under the curve (AUC) to maximize sensitivity and specificity in diagnosing full-syndrome AN, whereas the EDE-Q did not. Based on chi-square analyses, the PEDE-Q identified a statistically significantly greater number of AN cases than the EDE-Q. The EDE-Q yielded a BN diagnosis more frequently than the PEDE-Q, although this difference was not statistically significant.

DISCUSSION

Results suggest that the PEDE-Q has good psychometric properties and provides incremental information that can aid in the assessment and diagnosis of adolescents with EDs, particularly those with AN.

PUBLIC SIGNIFICANCE

There exist complex challenges to identifying clinically significant eating disorders among youth. The PEDE-Q is a questionnaire measure that improves eating disorder assessment among children and adolescents by asking parents to report on the symptoms and behaviors they have observed in their child and that youth may not fully disclose. The PEDE-Q can aid in the diagnosis of adolescents with eating disorders, particularly those with anorexia nervosa.

Expressed emotion and treatment outcome in higher levels of care for eating disorders

OBJECTIVE

Expressed emotion (EE) among caregivers toward the affected offspring is a negative prognostic indicator for adolescent patients with eating disorders (EDs) in outpatient treatment. Less research has examined its impact on adolescents in higher levels of care (HLOC). The current study examined differences in caregiver EE according to the subtype of anorexia nervosa (AN) (restricting [AN-R] versus binge/purge [AN-BP]), and level of care (LOC). We also examined the main effects of baseline caregiver EE (emotional overinvolvement [EOI] or criticism), AN subtype, and their interaction on eating pathology and depression at discharge.

METHOD

Adolescent patients (N = 203) receiving treatment at HLOCs completed measures of ED pathology (Eating Disorder Examination-Questionnaire) and depression (Patient Health Questionnaire-9) at baseline and discharge, and one caregiver of each patient completed a measure of EE (Family Questionnaire) at baseline.

RESULTS

No differences in caregiver EE were found between patients with AN-R versus AN-BP, or relative to LOC. Caregiver EE did not predict outcome for ED symptoms or depression at discharge.

DISCUSSION

The impact of high caregiver EE may be less substantial at HLOCs than outpatient care given that caregivers are less involved in treatment at HLOCs. Future research is needed to determine if high caregiver EOI leads to poor treatment outcome for adolescents as it does for adults, or whether it is an appropriate expression of care for patients who are ill enough to require HLOC treatment.

PUBLIC SIGNIFICANCE STATEMENT

High caregiver EE was not found to predict treatment outcome for adolescents with eating disorders in higher levels of care (HLOCs), possibly due to the limited involvement of caregivers in HLOCs. However, patients step down to outpatient treatment, where high caregiver EE can have a significant negative impact on outcome. HLOCs should incorporate efforts to reduce high caregiver EE in anticipation of step-down to outpatient treatment.

Care utilization in eating disorders: for whom are multiple episodes of care more likely?

PURPOSE

The current study aimed to determine baseline clinical features among adults receiving varied levels of care for transdiagnostic eating disorders (N = 5206, 89.9% female, mean age 29 years old) that may be associated with increased care utilization.

METHODS

We used negative binomial regression models to evaluate associations among eating disorder diagnoses, other psychiatric features (e.g., lifetime history of comorbid disorders), and the number of episodes of care for treatment of the eating disorder.

RESULTS

Having a diagnosis of binge eating disorder (p < .001) or avoidant restrictive food intake disorder (p = .04) were associated with lower odds of readmissions. A lifetime diagnosis of major depressive disorder (p < .001) or self-injury (p < .001) was each associated with significantly higher odds of readmissions.

CONCLUSIONS

Care utilization may differ according to eating disorder diagnosis, with a likelihood of increased readmission for those with a history of mood disorder or self-injury. Identification of individuals with greater vulnerability for eating disorder care utilization holds potential in aiding treatment and discharge planning, and development.

LEVEL OF EVIDENCE

Level III: evidence obtained from well-designed cohort or case-control analytic studies.

Avoidant restrictive food intake disorder and suicidal ideation

Most DSM-5 eating disorder diagnoses are associated with elevated suicide risk; however, little is known about the relationship between Avoidant/Restrictive Food Intake Disorder (ARFID) and suicidal ideation. The aim of the current study was to examine suicidal ideation within an adult ARFID sample. Patients with eating disorders (N = 936), some of whom met criteria for a current DSM-5 diagnosis of ARFID (n = 79), completed the Beck Depression Inventory II Item 9, regarding suicidal ideation. The study was conducted within an eating disorder treatment facility that offers inpatient, residential, partial hospitalization program, and intensive outpatient levels of care. Findings suggest no significant pairwise differences in suicidal ideation prevalence between participants with ARFID and those with any other ED diagnosis. Thorough screening for suicidal thoughts and risk among those with ARFID is warranted at all levels of care. We suggest that future research expand upon this work in a larger adult ARFID sample.

Understanding non-routine discharge: Factors that are associated with premature termination from higher levels of care in adults with anorexia nervosa

This study sought to replicate and extend associations between clinical and demographic features at admission and types of premature treatment termination for adults diagnosed with anorexia nervosa (AN) in higher-level-of-care settings. Secondary data analyses examined a study population comprised of adults with AN (N = 565) who were admitted to one of two United States eating disorder treatment centers (April 2015-April 2020) for intensive outpatient, partial hospitalization, residential, or inpatient services. There were no significant differences in the type of non-routine discharge according to level of care. At admission, those with lower BMI were more likely to discharge against medical advice, and those with lower cognitive restraint and elevated binge eating were more likely to discharge against medical advice or by staff-initiated request, respectively. Discharge by parent/patient request was more likely among those who were older or who reported lower baseline desire for muscularity. Overall older age, elevated binge eating, and lower weight, desire for muscularity, and cognitive restraint may be associated with less tolerance/acceptability for AN treatment. Increased understanding of how to better support patients who admit to higher levels of care with these clinical features will contribute to better odds of completion of a full course of treatment.

Comparing eating disorder treatment outcomes of transgender and nonbinary individuals with cisgender individuals

OBJECTIVE

The purpose of this study was to compare symptom severity of eating disorders (EDs), depression and anxiety at admission and discharge for transgender and nonbinary (TNB) individuals and cisgender adult individuals receiving treatment for EDs at higher levels of care (HLOC), adding to the limited research in this area.

METHOD

Participants were 25 TNB individuals and 376 cisgender individuals admitted to a HLOC ED treatment facility. Participants completed the Eating Disorder Examination Questionnaire (EDE-Q), Patient Health Questionnaire-9, and Beck Anxiety Inventory at admission and discharge.

RESULTS

TNB individuals showed significant improvements on EDE-Q global scores between admission and discharge (Cohen's d = 1.27), and showed similar improvements on the EDE-Q over the course of treatment (Cohen's d = 0.06) when compared to cisgender individuals. TNB individuals had more severe depression at admission (Cohen's d = 0.61). Although depression improved over the course of treatment for both groups, TNB individuals showed less improvement (Cohen's d = 0.59). Suicidality was higher for TNB individuals on admission and discharge and did not improve significantly over the course of treatment (Cohen's d = 0.38).

DISCUSSION

This study provides preliminary evidence that TNB and cisgender individuals show similar improvement in ED symptoms during HLOC treatment. However, TNB individuals have more severe depression and less improvement in depression compared to cisgender individuals, without improvement in suicidality. TNB individuals may benefit from care targeting depression and suicidality during ED treatment.

PUBLIC SIGNIFICANCE STATEMENT

TNB individuals have increased risk of EDs. Little research addresses how TNB individuals respond to ED treatment, which was traditionally created for cisgender individuals. We present one of the first studies examining ED treatment outcomes for TNB adults. TNB individuals showed improved ED symptoms with treatment, but less improvement in depression and their suicidality remained elevated. This suggests the need for targeted treatment.

Eating disorder behaviors as predictors of suicidal ideation among people with an eating disorder

OBJECTIVE

Suicidality is known to be elevated among people with an eating disorder. The aim of the current study was to examine whether any of three specific behavioral facets of eating disorders (i.e., purging, binge eating, restricting) would be the strongest predictors of suicidal ideation, controlling for one another, in longitudinal analyses from admission to discharge. We hypothesized that purging, above and beyond restricting or binge eating, would be the most important predictor of suicidal ideation.

METHOD

In the present study, patients with an eating disorder (N = 936), the majority of whom met criteria for a current DSM-5 diagnosis of Anorexia Nervosa (n = 560), completed the Eating Pathology Symptoms Inventory (EPSI) and the Beck Depression Inventory II-Item 9 suicidal ideation index, at admission and again at discharge. The settings were eating disorder treatment facilities offering inpatient, residential, partial hospitalization program (PHP), and intensive outpatient (IOP) levels of care. We pitted EPSI purging, EPSI restriction, and EPSI binge eating against one another in a regression framework predicting discharge suicidal ideation controlling for suicidal ideation at admission.

RESULTS

EPSI Purging significantly predicted both presence/absence of suicidal ideation (β = .22, t = 2.48, p = .01; OR = 1.25, 95% CI [1.05, 1.49]) and intensity of suicidal ideation (β = .04, t = 2.31, p = .02) at discharge, whereas neither EPSI Restricting nor EPSI Binge Eating did (p > .30).

DISCUSSION

Study results suggest that purging may have particular relevance in estimating suicide risk in patients with an eating disorder.

Meta-Analysis and Systematic Review of Resting-State High-Frequency Heart Rate Variability in Binge-Eating Disorder

Abstract. Binge-eating disorder (BED) is associated with a greater risk for cardiac problems and co-occurring health conditions. Resting-state measures of high-frequency heart rate variability (HF-HRV), which is a physiological proxy of self-regulatory neural functioning, may aid understanding of health risks. We systematically reviewed and meta-analyzed the literature on HF-HRV in individuals with BED and without BED. Six studies were reviewed in the qualitative synthesis, and five studies assessing HRV in individuals with BED ( n = 153) and without BED ( n = 124) were included in the meta-analysis. A non-significant effect size (Hedges’ g = .08, SE = 0.36, 95% CI [−0.62, 0.78]; z = 0.23, p = .82) was found, suggesting no difference in HF-HRV between groups. Age, BMI, and BMI-matched control status were not significant covariates. Synthesizing the five studies with available data, we found no difference in resting-state HF-HRV between individuals with and without BED. There was high heterogeneity in the sample, suggesting potential moderators. We discuss potential mechanisms, methodological and demographic confounds, and future directions for study.

Weight gain and parental self-efficacy in a family-based partial hospitalization program

BACKGROUND

Family-based treatment (FBT) is an outpatient therapy, though FBT principles have been incorporated in higher levels of care (e.g., partial hospitalization programs, PHPs). It is unknown how participation in a family-based PHP impacts weight restoration and parental self-efficacy.

METHODS

Weight gain and parental self-efficacy were examined in 98 participants with anorexia nervosa or atypical anorexia nervosa during the first five weeks of participation in a family-based PHP. Maternal self-efficacy was assessed using the Parent versus Anorexia Scale.

RESULTS

Significant increases in weight, percent expected body weight (EBW), and maternal self-efficacy were observed, with large effect sizes. During the first five weeks of treatment, patients in the PHP gained an average of 4.5 kg, or 8.3% EBW. Maternal self-efficacy improved within two weeks of treatment.

CONCLUSIONS

Findings suggest that family-based PHPs may facilitate rapid weight restoration without decreasing parental self-efficacy. Randomized trials are needed to directly compare family-based PHPs to outpatient FBT and PHPs with alternate treatment approaches, including longer-term follow-up and cost-effectiveness modeling.

Phase 2 of family-based treatment: an exploratory assessment of clinician practices

PURPOSE

In manualized family-based treatment (FBT) for eating disorders, phase 1 of the 3-phase treatment-during which parents are put in control of eating-related issues-is perhaps the most critical phase, and is comprehensively addressed in the manual. Phase 2, during which control over eating is gradually returned to the patient, is more variable and the manual dedicates less space to this phase. The purpose of the current exploratory study was to assess Phase 2 practices of clinicians providing FBT and to compare these practices to the guidance offered in the manual.

METHODS

In the current study, a survey assessing Phase 2 practices was sent to clinicians. Twenty-seven providers responded. Two providers reported that they did not provide FBT in an outpatient setting. One reported not currently providing outpatient FBT but had in the past. The remaining providers were currently providing FBT in an outpatient setting.

RESULTS

No items addressing the core interventions of Phase 2, including encouraging age-appropriate independent eating, were endorsed by 100% of respondents as being addressed 100% of the time in Phase 2.

CONCLUSION

Responses reflected some adherence to the manual, along with examples of therapist drift and incorporation of therapeutic interventions that are not described in the FBT manual. Adherence to manualized treatments may improve outcome for some patients, while allowing for flexibility to address clinical situations that are not addressed in the manual.

Structural validity of the Eating Disorder Examination-Questionnaire: A systematic review

OBJECTIVE

The main aim was to perform a systematic literature review of studies investigating the factor structure of the Eating Disorder Examination-Questionnaire (EDE-Q), a widely used measure of eating pathology. Secondary aims were to summarize the quality of reporting of latent variable (factor) analyses in these studies and review support for different factor solutions.

METHOD

Literature was identified through Scopus, Medline, PsycInfo, and ProQuest databases published up to February 23, 2022 and outreach via an international listserv. All studies published in English reporting factor analysis of the EDE-Q were included with few restrictions. Sixty studies including 63,389 participants met inclusion criteria.

RESULTS

The originally proposed four-factor solution received little empirical support, although few alternative models have been robustly evaluated. Items assessing shape and weight concerns frequently coalesce in factor solutions, suggesting that these constructs are closely related. Investigations of brief versions of the EDE-Q have produced more consistent findings, suggesting that these measures, particularly a seven-item version, might be useful alternatives to the full version. Quality of studies was reasonable, with important methodological elements of factor analysis often reported.

DISCUSSION

The findings are of relevance to practitioners and researchers, suggesting that the "original" factor structure of the EDE-Q should be reconsidered and that use of a seven-item version is to be encouraged.

PUBLIC SIGNIFICANCE

Self-report questionnaires are widely used in the assessment of disordered eating. The current study found that there is little consensus about the structure of a common measure of eating psychopathology. There is more consistent support for a brief, seven-item, version assessing dietary restraint, body dissatisfaction, and overvaluation of weight and shape.

Treatment Outcome for Adults in a Residential Program for Binge Eating Spectrum Disorders: Protocol for a Prospective Pragmatic Single-Arm Trial

Background

Most studies reporting treatment outcomes for eating disorders at higher levels of care focus on anorexia nervosa and bulimia nervosa. No studies have been published with a singular focus on examining treatment outcomes for adults receiving residential programming specifically designed for the treatment of binge eating spectrum disorders (BESD), including binge eating disorder and bulimia nervosa.

Objective

The purpose of this paper is to outline the protocol of a prospective study examining treatment outcomes at discharge and 3-month, 6-month, and 12-month postdischarge follow-up, for a sample of consecutive admissions to a residential program specifically for patients with BESD.

Methods

One hundred consecutive admissions to a binge eating treatment program were enrolled in the prospective single-arm trial between January 2019 and February 2020. Data were collected at admission, discharge, and 3, 6, and 12 months postdischarge, with admission, discharge, and 12-month follow-up as the major timepoints of interest. Results across the major timepoints will be analyzed with mixed effects general linear models.

Results

The primary aim is to assess the impact of the program on eating disordered behaviors at discharge and 12-month follow-up, which are hypothesized to improve as a result of treatment. Secondary hypotheses include improvements on comorbid symptoms, including trauma, depression, and obsessive-compulsive symptoms, as well as improvements on medical indicators of health, including cholesterol and triglycerides, at discharge and 12-month follow-up.

Conclusions

This study may aid in the development of treatment guidelines for patients with BESD at higher levels of care and lend support to having specialty treatment programs for patients with BESD.

Adverse childhood experiences among adults with eating disorders: comparison to a nationally representative sample and identification of trauma

BACKGROUND

Adverse childhood experiences (ACEs) are prevalent, impact long-term physical and mental health, and are associated with eating disorders (EDs) in adulthood. The primary objectives of the current study were: (1) to examine and compare ACEs between two samples: treatment-seeking adults, and a nationally representative sample of adults, (2) to characterize ACEs items and total scores across demographic and diagnostic information in adults seeking treatment for an ED, (3) to statistically classify ACEs profiles using latent class analysis, and (4) to examine associations between ACEs profiles and diagnosis.

METHODS

This cross-sectional study assessed patients with a DSM-5 ED receiving treatment between October 2018 and April 2020 at the inpatient, residential, or partial hospitalization levels of care at one of two private ED treatment facilities. ACEs were assessed with the Adverse Childhood Experiences Survey at admission. Generalized linear models and Welch's t-tests were used to compare ACEs in the current sample with national estimates. A latent class analysis was conducted to examine subgroups of ACEs responses, and differences in these classes by ED diagnoses were examined with multinomial logistic regression.

RESULTS

Patients with EDs had significantly higher ACEs scores (M = 1.95, SD = 1.90) than the nationally representative sample (M = 1.57, SD = 4.72; t = 6.42, p < .001). Within patients with EDs, four latent classes of ACEs item endorsement were identified. Patients with other specified feeding or eating disorder (OSFED) and binge eating disorder (BED) were more likely to fall into the "Household ACEs" and "Abuse ACEs" groups, respectively, compared to anorexia nervosa-restricting subtype (AN-R).

CONCLUSIONS

Patients with EDs reported more ACEs than the nationally representative sample, and differences in total ACEs and latent class membership were found across ED diagnoses. The current study can inform the development of trauma-informed care for patients with EDs.

The five tenets of family-based treatment for adolescent eating disorders

Family-based treatment (FBT) is the leading treatment for adolescent eating disorders and is based on five tenets, or fundamental assumptions: (1) the therapist holds an agnostic view of the cause of the illness; (2) the therapist takes a non-authoritarian stance in treatment; (3) parents are empowered to bring about the recovery of their child; (4) the eating disorder is separated from the patient and externalized; and (5) FBT utilizes a pragmatic approach to treatment. Learning these tenets is crucial to the correct practice and implementation of manualized FBT. The purpose of the current paper is to provide an in-depth overview of these five tenets and to illustrate how they are used in clinical practice. This overview will aid clinicians who are learning FBT.

Adverse childhood experiences among a treatment-seeking sample of adults with eating disorders

OBJECTIVE

The purpose of the current study was to examine the prevalence of adverse childhood experiences (ACEs) among adults with eating disorders (EDs), to assess whether experiencing a greater number of ACEs is associated with more severe ED psychopathology, and to determine whether ACEs predict treatment outcome.

METHOD

Participants were 1819 patients (88.5% female, ages 18-72) admitted to one of two treatment facilities at inpatient, residential, or partial hospitalisation levels of care. The Adverse Childhood Experiences Survey and the Eating Pathology Symptom Inventory (EPSI) were completed at admission and the EPSI at discharge.

RESULTS

Female patients reported higher ACEs than males (p = 0.03), and all diagnoses except avoidant/restrictive food intake disorder had significantly higher ACEs than patients with anorexia nervosa-restricting type (AN-R) (p's < 0.01). Across diagnoses, higher ACEs were associated with decreases in binge eating scores during treatment, but were not associated with changes in purging or restricting. Within diagnoses, higher ACEs scores were associated with decreases in purging for patients with AN-R and increases in purging for patients with binge eating disorder.

CONCLUSIONS

Results partially supported the hypothesis that higher ACEs would be associated with more severe ED psychopathology.

Predictors of improvement in a family-based partial hospitalization/intensive outpatient program for eating disorders

The efficacy of family-based treatment (FBT) in outpatient settings has led to efforts to incorporate FBT principles into higher levels of care. The present study examined predictors of improvement in an FBT-based partial hospitalization program/intensive outpatient program (PHP/IOP) as measured by the Eating Disorder Examination-Questionnaire. Participants were 113 patients with anorexia nervosa (AN) or eating disorder not otherwise specified (EDNOS) consecutively participating in an FBT-based PHP/IOP. Multilevel modeling was used to investigate predictors for adolescents and young adults separately. Predictors considered included illness duration, previous hospitalization, hospitalization immediately prior to treatment, previous outpatient therapy, hospitalization during treatment, diagnosis, gaining 4 pounds in 4 weeks, and family status as time-invariant variables. Time-varying variables considered included depression symptoms and mothers'/fathers' ratings of parental self-efficacy and expressed emotion. For adolescents, depression by time and diagnosis by time interactions were statistically significant. At all levels of depression, adolescent patients with AN demonstrated greater reductions in eating disorder symptoms compared to patients with EDNOS. For young adults, depression and gaining 4 pounds in 4 weeks were significant predictors. The relationships for young adults were curvilinear such that, while lower eating disorder symptoms were found during treatment, these gains were not maintained at follow up.

Expressed emotion and long-term outcome among adolescents with anorexia nervosa

OBJECTIVE

The purpose of the current study is to examine expressed emotion (EE) and long-term treatment outcome among adolescents participating in a randomized controlled trial (RCT) for treatment of anorexia nervosa (AN). It was hypothesized that patients with high EE parents at baseline would show more severe symptoms at end-of-treatment, 12-month follow-up, and 4-year follow-up than patients from low EE families.

METHOD

Secondary data analysis was conducted of original RCT data from a two-site eating disorder treatment trial conducted in the United States. Participants were 121 adolescents with AN who completed measures of EE, eating disorder psychopathology, depression, and self-esteem.

RESULTS

Generalized estimating equations showed that participants who were in the Low EE group achieved a more accelerated drop in depression scores in the context of treatment (first 12 months) than participants in the High EE group. No other significant Group × Time interactions were found.

DISCUSSION

Findings suggest that high parental EE at baseline does not indicate that adolescent patients with AN will fare poorly 4 years later.

Changes in meal-related anxiety predict treatment outcomes in an intensive family-based treatment program for adolescents with anorexia nervosa

Meal-related anxiety in individuals with eating disorders is associated with reduced caloric intake and persisting eating-disordered behaviors, which may reduce the likelihood of attaining or sustaining remission. The current study is the first to examine changes in meal-related anxiety as a predictor of outcomes in the context of a family-based partial hospitalization program. A sample of 51 adolescents with anorexia nervosa or atypical anorexia rated anxiety before and after all treatment meals using the Subjective Units of Distress Scale (SUDS). Regression analyses suggested that participants experiencing a greater reduction in meal anxiety endorsed fewer eating disordered symptoms on the EDE at the end of treatment. Reductions in meal anxiety did not predict EBW at end of treatment, which could be because family-based treatment (FBT) supports adequate food intake regardless of meal anxiety (i.e., parents ensure food intake). Findings suggest that reductions in meal-related anxiety may be an important predictor of outcomes in family-based interventions, and future research is needed to examine if directly targeting meal anxiety may enhance outcomes.

Motivation to recover for adolescent and adult eating disorder patients in residential treatment

OBJECTIVE

This study aimed to assess how baseline motivation to recover impacts eating disorder (ED) and comorbid symptoms at end-of-treatment (EOT) for adolescents and adults in inpatient/residential treatment.

METHOD

Two hundred and three adolescent (M = 15.90) and 395 adult (M = 25.45) patients with a Diagnostic Statistical Manual, 5th edition ED diagnosis completed the Decisional Balance Scale (DBS) at baseline, and psychosocial measures (ED symptoms, anxiety, depression, obsessive-compulsive disorder symptoms), and %body mass index (kg/m² ; BMI) or median %BMI (for adolescents) at baseline and EOT.

RESULTS

The DBS Avoidance Coping and Burdens subscales at baseline were significantly lower for adolescents than adults (p < 0.001), whereas the DBS Benefits subscale at baseline did not significantly differ between subsamples (p = 0.06). Motivation to recover via DBS subscales was a more reliable predictor of EOT outcomes for both ED and comorbid psychopathology in adults (significant predictor in 19 of 54 total analyses, and 4 significant associations post-Bonferroni correction) than adolescents (significant predictor in 5 of 54 total analyses, and 1 significant association post-Bonferroni correction).

CONCLUSIONS

Baseline motivation to recover may be an important predictor of outcome for adult patients in inpatient/residential treatment but does not appear associated with outcomes for adolescent patients.

Posttraumatic stress disorder symptoms and trauma-informed care in higher levels of care for eating disorders

OBJECTIVE

The purpose of the current study was to examine the prevalence and trajectory of posttraumatic stress disorder (PTSD) symptoms among patients with eating disorders (EDs) in higher level of ED care with trauma-informed components, but without a formal evidence-based trauma intervention.

METHOD

Participants were 613 adults diagnosed with EDs receiving treatment at inpatient, residential, or partial hospitalization levels of care. Participants completed the PTSD Checklist-5 (PCL-5) at admission and discharge.

RESULTS

Over half of patients scored above the cutoff of 33 on the PCL-5 at admission, suggestive of PTSD symptoms characteristic of a formal PTSD diagnosis. The average PCL-5 score significantly decreased for every ED diagnostic category, and there was a significant reduction in the proportion of patients above the PCL-5 cutoff score at discharge. PCL-5 subscales measuring PTSD criteria B (intrusions) and C (avoidance) improved with modest effect sizes, whereas PCL-5 subscales D (negative alterations in cognitions and mood) and E (alterations in arousal and reactivity) improved with larger effect sizes.

DISCUSSION

PTSD symptoms are prevalent among patients with EDs seeking higher levels of care. Despite not offering evidence-based trauma-specific interventions, PTSD symptoms decreased over the course of treatment. However, improvements cannot definitely be attributed to trauma-informed care.

Gender identity, race/ethnicity and eating pathology in a treatment-seeking community sample

Despite the wide-reaching impact of eating disorders (EDs), less is known about eating pathology among individuals across racial/ethnic groups whose gender identity differs from the binary categorization. Examining ED pathology both across binary and minority-gender groups, and relative to racial/ethnic identification is necessary to inform screening and culturally-sensitive intervention efforts. This study investigated patterns of ED symptomology among youth and adults (N = 13658) who telephoned treatment centers in the United States when seeking clinical support for ED symptoms. Analyses examined data from participants who completed a semi-structured clinical interview. Results indicated that Anorexia nervosa was the most common diagnosis in each gender category and for a majority of race/ethnic groups; Black individuals had elevated rates of binge eating disorder. Compared to females, males were less likely to endorse all ED symptoms (ps < .001); gender minority status was also associated with decreased report of a majority of ED symptoms. Asian and Black individuals were less likely than Whites to endorse most ED symptoms. When compared to Whites, Hispanic/Latinx and Bi/Multi-racial participants did not demonstrate significant differences in presentation across a majority of ED symptoms. Overall findings suggest individuals with female gender and White race may seek treatment from an ED treatment facility with greater frequency than other demographic groups. Noted exceptions include Hispanic/Latinx and Bi/Multi-racial individuals, for whom ED pathology may be represented comparably to Whites. While findings confirm traditional patterns in gender and racial/ethnic representation in EDs, current study findings also underscore that EDs are not culture bound.

Pilot assessment of a virtual intensive outpatient program for adults with eating disorders

Access to evidence-based treatment for eating disorders is severely limited by patient barriers and available clinician training. While clinical parameters often point to the need for a high level of care, patients may resist pursuing higher levels of care due to these barriers. One option that might mitigate such obstacles is the provision of a higher level of care via internet-based treatment for eating disorders. We sought to determine the feasibility, acceptability, and preliminary clinical outcomes associated with treatment of eating disorders through virtual intensive outpatient programming (VIOP). Fifty-seven patients meeting DSM-5 criteria for an eating disorder participated in VIOP. Of the 57 patients in VIOP treatment, 3 did not complete voluntary measures at admission or discharge, and 9 additional patients did not complete voluntary measures at discharge. Overall, 45 VIOP patients completed admission and discharge assessments, including a net promoter score (NPS) question assessing patient acceptability. Recruitment, treatment adherence, and completion of assessments in VIOP were feasible and acceptable. VIOP patients showed significant and clinically meaningful improvements in all outcomes measured, including self-reported eating disorder symptoms, depression, self-esteem, quality of life, and overall satisfaction. VIOP appears feasible, acceptable, and evidences clinically meaningful changes in eating and mood disorder symptoms.

Adapting treatment in an eating disorder program to meet the needs of patients with ARFID: Three case reports

Avoidant/restrictive food intake disorder (ARFID) was introduced in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. Three different subtypes of ARFID are described: individuals who seem disinterested in eating, those who avoid certain foods because of a sensitivity to specific characteristics of the food, and those who are concerned about an aversive experience associated with eating. There is currently no first-line treatment for ARFID. Three case studies are presented of patients with ARFID who participated in a family-based partial hospitalization program/intensive outpatient program for eating disorders. A description of the course of treatment is included, as well as ways in which the eating disorder program adapted treatment to more closely meet the unique needs of these patients. An approach with emphasis on parental involvement seems promising, although research is needed to investigate this more fully.

Brief report: Differences in nonsuicidal self-injury according to binge eating and purging status in an adolescent sample seeking eating disorder treatment

Nonsuicidal self-injury (NSSI) is elevated in adults with eating disorders (EDs), with a particularly increased incidence among individuals who engage in binge eating and/or purging (B/P) behaviors. Despite substantially elevated prevalence of NSSI in adolescence in general, NSSI in child and adolescent ED samples is understudied. There is some evidence for elevated prevalence of NSSI between B/P and restriction-only groups; however, this finding is not consistently reported and research in this area has excluded certain diagnostic groups (e.g., other specified feeding or eating disorder). Our aim was to identify the rates at which a transdiagnostic sample of adolescent patients with EDs (n = 155) report lifetime or past-month NSSI, and whether these rates differ between individuals who engaged in recent B/P behaviors vs. restriction only. Lifetime NSSI was present in 40.6% of the sample, and 23.2% of participants reported engaging in NSSI in the month prior to treatment. Individuals who reported recent B/P behaviors were more likely to report past-month (p = .005, OR = 5.57) and lifetime (p = .004, OR = 4.39) NSSI compared to individuals who did not report B/P behaviors. These results suggest an increase in risk for NSSI in child and adolescent patients in ED treatment who endorse B/P behaviors compared to patients who endorse restriction only. Research is needed to clarify the etiologic factors that may explain this association and the longitudinal changes in NSSI throughout the course of EDs.

Early weight gain predicts treatment response in adolescents with anorexia nervosa enrolled in a family-based partial hospitalization program

OBJECTIVE

Improved treatment outcome in family-based treatment (FBT) for anorexia nervosa (AN) is predicted by weight gain occurring early in the course of treatment (i.e., about 4 lbs by week 4). Although prior work suggests that early weight gain in higher levels of care (e.g., partial hospitalization programs [PHP]) predicts weight restoration at discharge, no study has examined the specific rate of gain within FBT-informed PHP programs that best predicts treatment response.

METHOD

This study examined rate of weight gain in pounds and percent expected body weight (EBW) that predicts positive outcome in 70 patients (M age = 15.49 years, SD = 2.56) with AN who were enrolled in a family-based PHP.

RESULTS

Receiver operator characteristic analyses demonstrated that changes in %EBW during weeks 2-5 were more useful than changes in weight in predicting positive outcome. Gaining at least 8.9 pounds or over 8% of EBW in the first 4 weeks of treatment significantly predicted positive outcome.

DISCUSSION

Findings suggest that positive outcome in an FBT-informed PHP is predicted by rapid weight gain in the initial weeks of treatment. Research is needed to identify specific family and patient characteristics that facilitate weight gain and to develop corresponding interventions to improve outcome.

The posited effect of positive affect in anorexia nervosa: Advocating for a forgotten piece of a puzzling disease

Anorexia nervosa (AN) is a complex and life-threatening eating disorder. Current models of AN onset and maintenance have largely focused on the role of negative affect, while fewer models have described the role of positive affect (PA). Given that these theoretical models have informed current treatment approaches, and that treatment remains minimally effective for adults with AN, we advocate that targeting PA is one avenue for advancing maintenance models and by extension, treatment. We specifically propose that AN may arise and be chronically and pervasively maintained as a function of dysregulated PA in response to weight loss and weight loss behaviors (e.g., restriction, excessive exercise), to a degree that is not accounted for in existing models of AN. We present evidence from multiple domains, including biological, behavioral, and self-report, supporting the hypothesis that PA dysregulation in AN contributes to the maintenance of the disorder. We conclude with several specific avenues for treatment development research as well as a call for future work elucidating the biological correlates of PA.

Desired weight and treatment outcome among adolescents in a novel family-based partial hospitalization program

The purpose of the current study was to investigate desired weight percentage and weight difference percentage and their association with treatment outcome in a novel family-based partial hospitalization program. Twenty-six adolescents with anorexia nervosa or subthreshold anorexia nervosa between the ages of 12 and 19 completed the Eating Disorder Examination (EDE) at intake and upon completion from a partial hospitalization program in which parents played a large role in the recovery process, consistent with family-based treatment principles. Lower desired weight percentage at baseline was associated with higher scores on the restraint subscale of the EDE at end of treatment. Higher weight difference percentage (greater desire to lose weight) at baseline was associated with higher scores on all EDE subscales and global score at end of treatment. Neither desired weight percentage nor weight difference percentage at baseline were associated with treatment dropout or percent expected body weight at end of treatment. In a family-based program, participants' desired weight may be related to eating disorder thoughts (for example, shape or weight concerns) but not to behavioral outcomes such as weight gain or treatment dropout, which may be more directly under the influence of the parents.

Heterogeneous weight restoration trajectories during partial hospitalization treatment for anorexia nervosa

Early response to treatment has been shown to predict good outcome in family-based treatment, but little is known about who responds quickly.

OBJECTIVE

The purpose of the current study was to examine the short-term weight gain trajectories among youth receiving partial hospitalization program services for anorexia nervosa (AN), and to identify predictors of these trajectories.

METHOD

Adolescent and young adults (n = 102) with AN or subthreshold AN completed semi-structured interviews and self-report measures on admission to a family-based partial hospitalization program. Patients participated in programming 5 days a week.

RESULTS

Three weight gain trajectories were found to indicate slow, moderate, and rapid weight gain trajectories. All rapid responders gained at least four lbs. in the first 4 weeks of treatment, compared to 86.1% of moderate responders and 51.2% of slow responders. Patients were less likely to have a moderate or rapid response trajectory if they had a mood disorder diagnosis and higher parental expressed emotion. Additionally, the presence of compensatory behavior increased the likelihood of having a rapid response.

DISCUSSION

Despite the sometimes chronic nature of AN, most patients fell into one of the two favorable response trajectories. The identification of these trajectories underscores the importance of considering the core disordered eating behaviors (i.e., restricting, binge eating, and purging), comorbid psychopathology, and parental expressed emotion.

Weight suppression as a predictor variable in the treatment of eating disorders: A systematic review

WHAT IS KNOWN ON THE SUBJECT?: Weight suppression (WS) has been suggested to predict outcome following psychological treatment for an eating disorder (ED). Some findings are contradictory and have not been considered systematically. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The review suggests that weight gain at post-treatment is reliably predicted by pretreatment WS, but findings regarding other outcomes (e.g., treatment dropout) are less consistent. Approximate effect sizes for observed relationships are identified, alongside support for biobehavioural theories of metabolic adaptation to weight loss. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Degree of WS at pretreatment is associated with weight gain and is important for clinicians to consider before offering treatment to patients with EDs. Patients high in WS might benefit from further support (e.g., psychoeducation) prior to beginning treatment. ABSTRACT: Introduction Weight suppression (WS-the difference between highest body weight and current body weight) has been proposed as a predictor of treatment outcome within eating disorders (EDs), although this hypothesis has not been consistently supported. Aim/Question Review the association between pretreatment WS and outcome following psychological treatment for EDs. Method A comprehensive electronic database search for published and unpublished literature from 1979 to 2017. Reference lists were also inspected. Eligibility criteria were determined according to relevant guidelines and a quality appraisal was conducted. Results Twelve studies met inclusion criteria (one was subsequently excluded based on insufficient data). Greater WS was generally associated with weight gain at post-treatment although not with other treatment outcomes. Discussion The existing evidence, with data from 1,566 participants, is summarized according to three main post-treatment outcomes: weight change; treatment completion; and symptom abstinence. Patients with disordered eating and greater WS may need to gain more weight than others during treatment to achieve good outcomes. Recommendations for future studies are provided. Implications for practice Evidence-based treatments for EDs may benefit from considering WS when planning treatment, such as further psychoeducation on weight changes. Societal interventions regarding promotion of healthy eating may also draw on these findings.

Three-month follow-up in a family-based partial hospitalization program

Family-based treatment principles have been incorporated into higher levels of care. However, outcome data for these programs, and, in particular, follow-up data, are limited. The current study assessed 3-month follow-up data for patients in a family-based partial hospitalization/intensive outpatient program. Patients completed measures of eating disorder psychopathology and depression, while parents completed measures of self-efficacy and expressed emotion. With the exception of paternal self-efficacy, all measures stayed the same or improved between end of treatment and follow-up, suggesting that improvements in a family-based higher level of care can be sustained once families step down to less intensive treatment.

Parental marital satisfaction in a family-based partial hospitalization program

In family-based treatment, parents are initially put in charge of the weight restoration process, requiring parents to work closely together to help their child recover, possibly putting a strain on the marital relationship. The purpose of the current study was to examine marital satisfaction in families before and after treatment in a family-based program and to determine whether marital satisfaction is related to patient outcome. Parents of 53 adolescent patients participated in the study. Almost half of mothers and a third of fathers reported a decrease in marital satisfaction over the course of treatment. Descriptive analyses revealed that patients whose parents reported a decrease in marital satisfaction scored worse on a measure of eating disorder psychopathology. Further research is needed to determine the direction of causality.

Psychopathology and expressed emotion in parents of patients with eating disorders: Relation to patient symptom severity

The purpose of the current study was to examine the relation between parental psychopathology, parental expressed emotion, and patient symptom severity. One hundred twenty-six parents of 79 patients receiving treatment for an eating disorder completed measures of expressed emotion and general psychopathology, and patients completed a measure of eating disorder psychopathology. Mothers reported higher expressed emotion scores than fathers. Both mothers and fathers scored higher on general psychopathology compared to nonpatient population means. Maternal psychopathology was found to be associated with symptom severity. Parental psychopathology and expressed emotion were found to be related, and MANCOVAs revealed that maternal criticism and maternal psychopathology were associated with patient symptom severity, but fathers' scores on the same measures were not. It is recommended that parental expressed emotion and parental psychopathology are assessed at the beginning of treatment so that appropriate clinical interventions can be utilized.

Family-based treatment of eating disorders in adolescents: current insights

Eating disorders are serious illnesses associated with significant morbidity and mortality. Family-based treatment (FBT) has emerged as an effective intervention for adolescents with anorexia nervosa, and preliminary evidence suggests that it may be efficacious in the treatment of adolescents with bulimia nervosa. Multifamily therapy for anorexia nervosa provides a more intensive experience for families needing additional support. This review outlines the three phases of treatment, key tenets of family-based treatment, and empirical support for FBT. In addition, FBT in higher levels of care is described, as well as challenges in the implementation of FBT and recent adaptations to FBT, including offering additional support to eating-disorder caregivers. Future research is needed to identify families for whom FBT does not work, determine adaptations to FBT that may increase its efficacy, develop ways to improve treatment adherence among clinicians, and find ways to support caregivers better during treatment.

Patterns of expressed emotion in adolescent eating disorders

BACKGROUND

This goal of this study was to understand the patterns of expressed emotions (EEs) in adolescent eating disorders. As such, this study compared EE among families of adolescents with anorexia nervosa (AN), bulimia nervosa (BN), and a psychiatric control group, major depressive disorder (MDD). This study also examined the influence of family status (intact vs. nonintact) and the presence of siblings on EE.

METHODS

Two-hundred and fifteen adolescents (ages 12-19) and their families were recruited for this study including 121 adolescents with AN, 54 adolescents with BN, and 40 adolescents with MDD. Adolescents with at least one parent completed the Standardized Clinical Family Interview. Adolescents completed structured diagnostic interviews to assess eligibility for the study, as well as a standardized questionnaire to assess depression.

RESULTS

Analyses revealed that fathers showed higher levels of critical comments to adolescents with BN or MDD than those with AN, whereas mothers made more critical comments toward patients with BN. Mothers made the least number of positive remarks toward patients with MDD. In terms of the influence of family status, fathers from intact families showed more expressions of warmth and were less critical than fathers from nonintact families, whereas mothers from intact families were less critical but also made fewer positive remarks than mothers from nonintact families. The presence of siblings appeared to reduce mothers' expression of warmth and emotional overinvolvement.

CONCLUSIONS

Unique patterns of EE were found to characterize AN, BN, and MDD. Family status and the presence of siblings exert an influence on EE that should be taken into consideration in future research.

Therapeutic alliance, expressed emotion, and treatment outcome for anorexia nervosa in a family-based partial hospitalization program

Adolescent therapeutic alliance has been found to be associated with improvements in eating disorder cognitions and with early weight gain. The current study assessed patient and parent therapeutic alliance, correlates of parent alliance, and relationship between alliance and treatment outcome. Fifty-six patients with anorexia nervosa completed measures of therapeutic alliance and eating disorder symptoms. Patients' parents completed measures of therapeutic alliance, expressed emotion, and psychopathology. Patients' alliance predicted cognitive and behavioral symptomatology at end of treatment (β=-0.39, p=0.001), though it was not related to changes in weight (β=0.12, p=0.377). Maternal hostility was associated with lower maternal alliance (r=-0.34, p=0.05). Findings suggest that maternal hostility should be addressed in treatment, and that patient alliance may be important in achieving psychological recovery from disordered eating.

Expressed Emotion, Family Functioning, and Treatment Outcome for Adolescents with Anorexia Nervosa

The current study examined the relation between parental expressed emotion (EE) and treatment outcome among adolescents participating in a treatment study for adolescent anorexia nervosa, as well as its impact on family functioning. One hundred and twenty-one families were assigned to family-based treatment or adolescent-focused therapy. Paternal criticism predicted lesser improvement in eating disorder psychopathology at end of treatment. There was also a significant interaction between maternal hostility and treatment, indicating that adolescents whose mothers displayed hostility had greater increases in percent of expected body weight in adolescent-focused therapy than family-based treatment. In addition, maternal hostility predicted less improvement in general family functioning and family communication at the end of treatment. Findings suggest that maternal and paternal EE may differentially impact treatment outcome and should be directly attended to in clinical settings. Future research is needed to further explore ways in which parental EE can be effectively modified in treatment.
