Understanding outcomes in family-based treatment for adolescent anorexia nervosa: a network approach.

BACKGROUND: Family-based treatment (FBT) is the first-line treatment for adolescent anorexia nervosa (AN). Yet, remission is not achieved for about half of adolescents with AN receiving FBT. Understanding patient- and parent-level factors that predict FBT response may inform treatment development and improve outcomes. METHODS: Network analysis was used to identify the most central symptoms of AN in adolescents who completed the Eating Disorder Examination (EDE) prior to FBT (N = 409). Bridge pathways between adolescent AN and parental self-efficacy in facilitating their child's recovery from AN were identified in a subset of participants (n = 184). Central and bridge symptoms were tested as predictors of early response (⩾2.4 kg weight gain by the fourth session of FBT) and end-of-treatment weight restoration [⩾95% expected body weight (EBW)] and full remission (⩾95% EBW and EDE score within 1 standard deviation of norms). RESULTS: The most central symptoms of adolescent AN included desiring weight loss, dietary restraint, and feeling fat. These symptoms predicted early response, but not end-of-treatment outcomes. Bridge symptoms were parental beliefs about their responsibility to renourish their child, adolescent discomfort eating in front of others, and adolescent dietary restraint. Bridge symptoms predicted end-of-treatment weight restoration, but not early response nor full remission. CONCLUSIONS: Findings highlight the prognostic utility of core symptoms of adolescent AN. Parent beliefs about their responsibility to renourish their child may maintain associations between parental self-efficacy and AN psychopathology. These findings could inform strategies to adapt FBT and improve outcomes.

The COVID-19 pandemic and youth with anorexia nervosa: A retrospective comparative cohort design.

OBJECTIVE: There is a growing body of literature suggesting the novel coronavirus pandemic (COVID-19) negatively impacts mental health in individuals self-reporting an eating disorder (ED); however, limited pediatric data is available about the impact COVID-19 has had on youth with EDs, specifically Anorexia Nervosa (AN). Our study uses a cross-sectional design to explore differences in ED symptoms between adolescents diagnosed with AN during the COVID-19 pandemic compared to a retrospective cohort of adolescents for whom these measures were previously collected, prior to the pandemic. METHOD: We report cross-sectional data assessing differences between AN behaviors and cognitions during the COVID-19 pandemic compared to a retrospective cohort (n = 25 per cohort) assessed before the pandemic. RESULTS: Results suggest that individuals with a first-time diagnosis of AN during the pandemic had lower percent expected body weight, and more compulsive exercise behaviors. CONCLUSIONS: These data support existing pediatric findings in exercise and body weight differences in adolescents with AN before and during the pandemic. Findings may be helpful in informing considerations for providers treating ED patients amidst and after the pandemic. PUBLIC SIGNIFICANCE: This manuscript compares a retrospective cohort of adolescents diagnosed with AN prior to the pandemic to a cohort of adolescents diagnosed with AN during the pandemic. Results report that adolescents diagnosed with AN during the pandemic have lower weights and increased compensatory exercise behavior compared to adolescents diagnosed with AN before the pandemic despite no difference in length of illness. Findings may be helpful in informing considerations for providers treating ED patients amidst and after the pandemic.

Predictors of family-based treatment for adolescent eating disorders: Do family or diagnostic factors matter?

OBJECTIVE: Misconceptions around which patients will and will not benefit from family-based treatment (FBT) for adolescent eating disorders (EDs) limit referrals and access to this treatment modality. The present study explored whether common demographic and clinical factors that may prevent referral to FBT predict treatment outcomes in adolescent anorexia nervosa (AN) and bulimia nervosa (BN). METHOD: The following predictors of treatment outcomes were assessed: baseline family and diagnostic factors (socioeconomic status, comorbidity, illness duration, parent feelings of self-efficacy, family status, prior treatment, sex and prior hospitalizations) in a combined sample of adolescents receiving FBT compared to those randomized to other treatment conditions, across six clinical trials in the United States and Canada (total n = 724, ages 12-18, 90% female across both diagnoses). AN and BN samples were examined separately. RESULTS: Any prior ED treatment emerged as the only predictor of outcome in AN and BN, such that having no prior treatment predicted better outcomes in FBT for AN, and in both FBT and other treatment modalities for BN. No other sociodemographic or clinical variables predicted outcomes for AN or BN in FBT or in other evidence-based treatment modalities. CONCLUSIONS: The findings of this exploratory analysis suggest that commonly assumed factors do not predict outcome in FBT. Specifically socioeconomic and demographic factors or clinical variability in families seeking treatment do not predict treatment outcomes in FBT, or other evidence-based treatment modalities, with the exception of prior treatment. Providers should consider referring to FBT even when these factors are present. PUBLIC SIGNIFICANCE: This manuscript reports that commonly assumed family, sociodemographic and diagnostic factors do not predict outcome in FBT or other evidence-based treatment modalities, with the exception of prior treatment. This data may be helpful for providers when considering referrals to FBT in the context of variability in these variables.

Evidence Based Update on Psychosocial Treatments for Eating Disorders in Children and Adolescents.

Eating disorders (EDs) are life-threatening psychiatric illnesses that occur in adolescents. Unfortunately, limited randomized controlled trials exist to address EDs in this vulnerable population. The current review updates a prior Journal of Clinical Child and Adolescent Psychology review from 2015. The recommendations in this review build upon those that were previously published. This update was completed through a systematic search of three major scientific databases (PsychInfo, Pubmed, and Cochrane) from 2015 to 2022 (inclusively) from three databases, employing relevant medial subject headings. Additionally, expert colleagues were asked for additional literature to include. Thirty-one new studies were added to this review. Psychosocial treatments included family therapies, individual therapy, cognitive-behavioral therapy, interpersonal psychotherapy, cognitive training, dialectical behavioral therapy, and more recently, virtual or telehealth-based practices and guided self-help modalities for carers of youth with EDs. Using the Journal of Clinical Child and Adolescent Psychology's methodological review criteria, this update found behavioral family-based treatment modalities (FBT) for both adolescent anorexia nervosa and bulimia nervosa met well-established treatment criteria. To date, there were no well-established treatments found for child and adolescent avoidant-restrictive food intake disorder, or binge eating disorder. Internet facilitated cognitive-behavioral therapy and family-based therapy were found to be possibly efficacious for binge eating disorder. Family-based treatment was found to be possibly efficacious for avoidant restrictive food intake disorder, with other clinical trials for cognitive treatment modalities under way. Ongoing research examining treatments for eating disorders in children and adolescents broadly is needed.

Is guided self-help family-based treatment for parents of adolescents with anorexia nervosa on treatment waitlists feasible? A pilot trial.

OBJECTIVE: The aim of the study was to assess the feasibility (recruitment and retention) of an online 12-session guided self-help family-based treatment (GSH-FBT) for families on the waitlist for face-to-face FBT utilizing trainee psychologists to assist carers of children with anorexia nervosa (AN) or atypical AN. METHOD: The primary outcomes were feasibility of GSH-FBT for families on the waitlist and secondary exploratory outcomes examined improvement of child and parental function. RESULTS: Of 187 eligible families on the waitlist, 24 (13%) expressed interest in the study; 16 (67%) of these families completed baseline, 13 (54%) completed GSH-FBT over a 6-month recruitment period. Children (mean age = 13.92, SD = .86; mean body mass index [BMI] centile = 29.47, SD = 24.80) had an average weight gain of 6 kg (BMI centile effect size = 2.61, 95% CI: 1.77-3.44) and a decrease in eating disorder behaviors (effect size = 1.11, 95% CI: .27-1.95). Improvements also occurred for general mood and behaviors in the child, and the impact of eating disorder symptoms on their functioning. Parents reported improvements in knowledge, skills, and confidence in managing AN. DISCUSSION: Use of this low-cost intervention while families are on the waitlist for FBT is engaging and useful but strategies to improve initial recruitment are needed. PUBLIC SIGNIFICANCE STATEMENT: Although most eligible families did not enroll in an online 12-session guided self-help family-based treatment for families on the waitlist for face-to-face FBT for anorexia nervosa, families who participated found it engaging. The children experienced improvements in BMI centile, eating and behavior. Parents reported increased confidence, knowledge, and skills. We need to examine how families can be encouraged to participate on online training when on waitlists for treatment.

Parent and clinician perspectives on virtual guided self-help family-based treatment (GSH-FBT) for adolescents with anorexia nervosa.

PURPOSE: Guided self-help (GSH) treatments have the capacity to expand access to care, decrease costs, and increase dissemination compared to traditional therapist-directed treatment approaches. However, little is known about parent and clinician perspectives about the acceptability of GSH for adolescents with eating disorders. METHODS: This study utilized a mixed methods approach to obtain qualitative and quantitative data regarding clinician and participants' experiences with GSH. Parent participants were enrolled in a randomized trial comparing GSH family-based treatment (GSH-FBT) to family-based treatment delivered via videoconferencing (FBT-V) for adolescents (12-18 years old) with a DSM-5 diagnosis of anorexia nervosa (AN). Parent participants provided qualitative feedback using the Helping Alliances Questionnaire about their experience of treatment. Clinician participants were six master's or PhD-level therapists. These clinicians were trained in and provided both treatments (GSH-FBT and FBT-V). They provided responses to questionnaires and participated in a 1-h focus group about their experience as treatment providers. RESULTS: Regardless of treatment condition, parents listed more improvement than worsening of symptoms in their child with AN. Clinicians reported lower scores on competency and comfort metrics with GSH-FBT compared to FBT-V. Qualitatively, clinicians reported both advantages and disadvantages of delivering GSH-FBT. CONCLUSION: Further studies are needed to better understand how GSH interventions can be disseminated to patients and families, particularly those with limited access to specialized eating disorder treatment centers. Level of evidence Level I, data collected as part of a randomized controlled trial.

Feasibility of conducting a randomized controlled trial comparing family-based treatment via videoconferencing and online guided self-help family-based treatment for adolescent anorexia nervosa.

OBJECTIVE: This report describes the feasibility, acceptability, and outcomes from a pilot randomized clinical trial (RCT) comparing an online guided self-help program version of family-based treatment (GSH-FBT) for parents with a child with DSM-5 anorexia nervosa (AN) to FBT delivered via videoconferencing (FBT-V). METHOD: Between August 2019 and October 2020, 40 adolescents ages 12-18 years with DSM-5 AN and their families were recruited at two sites and randomized to either twelve 20-min guided sessions of GSH-FBT for parents or fifteen 60-min sessions of FBT-V for the entire family. Recruitment, retention, and acceptability of treatment were the primary outcomes. Secondary outcomes were changes in weight, eating disorder examination (EDE), parental self-efficacy, weight remission, full remission, and outcome efficiency (therapist time needed to achieve treatment outcomes). RESULTS: Descriptive data are reported. Recruitment and retention rates are similar to RCTs using in-person treatments. Both treatments received similar acceptability rates. Medium and large effect sizes (ES) related to improvements in weight, EDE, parental self-efficacy, and remission were achieved in both treatments and were maintained at a 3-month follow-up. Clinical outcomes between groups were associated with a small ES. Differences in efficiency (outcome/therapist time) were associated with a large ES difference favoring GSH-FBT. DISCUSSION: These data support the feasibility of conducting an adequately powered RCT comparing online GSH-FBT to FBT-V to determine which approach is more efficient in achieving improvements in clinical outcomes in adolescents with AN.

Telehealth transition in a comprehensive care unit for eating disorders: Challenges and long-term benefits.

The 2019 novel coronavirus disease (COVID-19) pandemic has forced many eating disorder medical stabilization units to consider adjustments that uphold both the quality of care delivered to patients while also observing social distancing public health directives for patients and staff. To date, inpatient facilities for eating disorders (both medical stabilization units and higher level of care facilities) have not needed to consider how to translate services to electronic platforms, given that most of these programs have in-person staff. We outline our transition to telehealth broadly, emphasizing some unexpected benefits of using telehealth services that we plan on integrating into our work-flow post COVID-19. These may be useful for other higher level of care eating disorder programs, including medical stabilization units, residential, partial hospitalization, and intensive outpatient programs. We also highlight aspects of transition that have been more challenging for this particular patient population, warranting the need for in-person services.

Feeling and body investigators (FBI): ARFID division-An acceptance-based interoceptive exposure treatment for children with ARFID.

OBJECTIVE: Individuals with Avoidant Restrictive Food Intake Disorder (ARFID) experience impairing health consequences from insufficient nutritional variety and/or quantity. Early medical conditions and/or somatic symptoms such as abdominal pain may lead some with ARFID to experience somatic sensations as aversive. As such, food avoidance may be part of a broader behavioral repertoire aimed at suppressing bodily sensations. Avoiding these necessary and informative signals (e.g., growls of hunger) may subvert the emergence of healthy self-awareness and self-regulation. Teaching children with ARFID to engage adaptively with bodily sensations may help decrease aversiveness, increase self-awareness, and increase approach behaviors. METHOD: Drawing from interventions for panic disorder and irritable bowel syndrome, we developed an acceptance-based interoceptive exposure treatment for young children with ARFID, Feeling and Body Investigators (FBI)-ARFID Division. Using playful cartoons and developmentally sensitive exposures, we teach young children how to map interoceptive sensations onto meanings (e.g., emotions) and actions (e.g., if I feel nervous, I'll hold someone's hand). RESULTS: We present a case study of a 4-year old child with lifelong poor appetite/food indifference. DISCUSSION: Some individuals with ARFID may avoid food to avoid internal sensations. Developmentally appropriate interoceptive exposures may decrease ARFID symptoms while increasing more general self-regulation skills.

Central coherence in adolescents with bulimia nervosa spectrum eating disorders.

BACKGROUND: Weak central coherence-a tendency to process details at the expense of the gestalt-has been observed among adults with bulimia nervosa (BN) and is a potential candidate endophenotype for eating disorders (EDs). However, as BN behaviors typically onset during adolescence it is important to assess central coherence in this younger age group to determine whether the findings in adults are likely a result of BN or present earlier in the evolution of the disorder. This study examines whether the detail-oriented and fragmented cognitive inefficiency observed among adults with BN is observable among adolescents with shorter illness duration, relative to healthy controls. METHOD: The Rey-Osterrieth Complex Figure Test (RCFT) was administered to a total of 47 adolescents with DSM5 BN, 42 with purging disorder (PD), and 25 healthy controls (HC). Performance on this measure was compared across the three groups. RESULTS: Those with BN and PD demonstrated significantly worse accuracy scores compared to controls in the copy and delayed recall condition with a moderate effect size. These findings were exacerbated when symptoms of BN increased. DISCUSSION: Poorer accuracy scores reflect a fragmented and piecemeal strategy that interferes with visual-spatial integration in BN spectrum disorders. This cognitive inefficiency likely contributes to broad difficulties in executive functioning in this population especially in the context of worsening bulimic symptoms. The findings of this study support the hypothesis that poor global integration may constitute a cognitive endophenotype for BN.

Anorexia Nervosa Across the Lifespan: A Review of Recent Literature.

In this review, the authors provide an update on the understanding of anorexia nervosa (AN) across the lifespan. Focusing on key pieces of literature from the past 5 years, this review summarizes recent updates to DSM-5 within the domain of AN, including the addition of a new AN diagnosis: atypical anorexia. Additional sections covered in this review include improvements in the epidemiological understanding of AN across the developmental spectrum, treatment approaches that have been established as gold standard as well as new directions recently explored in treatment, and recent advancements in the biopsychosocial underpinnings of AN. Altogether, although this review captures several advancements in the field's overall conceptualization of AN, several key areas of treatment and diagnostic capacity continue to require additional focus and research.

Exploration of interoceptive capabilities in avoidant/restrictive food intake disorder and anorexia nervosa.

OBJECTIVE: This proof-of-concept study explores the role of aberrant interoception as a possible mechanism underlying restrictive eating symptoms in avoidant/restrictive food intake disorder (ARFID) compared to anorexia nervosa (AN) and healthy comparisons (HC). METHOD: We report preliminary normative adolescent interoceptive data in HCs (n = 100) compared to adolescents with ARFID (n = 30) and AN (N = 23). Adolescents (12-18) participated in a one-time virtual visit to assess heartrate guessing accuracy (interoceptive accuracy), correlation between confidence in heartrate guess and accuracy (interoceptive awareness), and self-reported interoception (interoceptive sensibility). RESULTS: HC adolescents had comparable interoceptive outcomes relative to published adult norms, consistent with existing literature. Data suggest that adolescents with ARFID have poor heartbeat guessing accuracy and experience challenges deciphering interoceptive signals, possibly contributing to symptoms. While adolescents with AN have greater heartbeat guessing accuracy, they cite difficulty trusting body cues, perhaps contributing to their lack of confidence in interoceptive cue detection. CONCLUSIONS: Preliminary results reflect differences in interoception between the three groups.

In this study, we wanted to understand how individuals with restrictive eating disorders, like avoidant/restrictive food intake disorder (ARFID) and anorexia nervosa (AN), sense and respond to different signals in their body, such as heartbeat. This process is called interoception. Difficulty sensing body signals can lead to various mental health disorders, such as eating disorders. We asked adolescent participants without an eating disorder and adolescents with ARFID and AN to guess their heartbeat while wearing a finger pulse oximeter, to track interoceptive accuracy (or how accurate their heartbeat guesses were). We also measured their self-reported sense of interoception and overall metacognitive awareness of their ability to accurately interpret body signals. Our data replicate findings in existing healthy teenagers. For teens with eating disorders, those with ARFID had difficulty with interoceptive accuracy and listening to their bodies, but they had good awareness overall of their accuracy. Teens with AN had better accuracy but were more unsure about trusting their body and body signaling. Overall, our initial findings suggest that how individuals with eating disorders sense, interpret, and respond to body signals might help explain their eating habits. More research is needed in this area.

Aberrant reward-related neural activation: Dimensional correlate of binge-eating severity or categorical marker of binge eating?

Binge eating (BE) is characterized by consuming an objectively large amount of food in a short period of time and experiencing loss of control over one's eating. The neural underpinnings of monetary reward anticipation and their association with BE severity remain poorly understood. Fifty-nine women aged 18 to 35 (M = 25.67, SD = 5.11) with a range of average weekly BE frequency (M = 1.96, SD = 1.89, range = 0-7) completed the Monetary Incentive Delay Task during fMRI scanning. Mean percent signal change within the left and right nucleus accumbens (NAc) during anticipation of monetary gain (versus non-gain) was extracted from a priori-defined functional 5 mm spheres and correlated with average weekly BE frequency. Exploratory voxel-wise whole-brain analyses examined the association between neural activation during anticipation of monetary reward and average weekly BE frequency. Body mass index and depression severity were covariates of non-interest in analyses. Mean percent signal change in the left and right NAc inversely correlated with average weekly BE frequency. Whole-brain analysis revealed no significant associations between neural activation during reward anticipation and average weekly BE frequency. In exploratory case-control analyses, mean percent signal change in the right NAc was significantly lower in women with BE (n = 41) versus women without BE (n = 18), but whole-brain analyses revealed no significant group differences in neural activation during reward anticipation. Decreased right NAc activity during monetary reward anticipation may distinguish women with and without BE.

Psychoeducational and motivational treatment for low-weight Avoidant/Restrictive Food Intake Disorder (ARFID): Three case reports in school-aged children.

BACKGROUND: Individuals with Avoidant/Restrictive Food Intake Disorder (ARFID) experience restrictive or highly selective eating problems that interfere with growth and development. Despite the increasing number of referrals for ARFID, no evidence-based treatments exist. This compilation of case composites describes a novel manualized treatment, Psychoeducational and Motivational Treatment (PMT) for children with ARFID, focusing on exploring motivation to change eating behaviors. This approach is based on motivational non-directive psychotherapy models, psychoeducational interventions, and the usefulness of play to support psychotherapeutic learning in school-age children. CASE PRESENTATIONS: Three cases of children with ARFID treated using PMT are presented: a 7-year-old, a 10-year-old, and a 12-year-old. These cases illustrate how a clinician delivers PMT interventions in the context of developmental abilities and common comorbidities associated with ARFID. CONCLUSION: PMT is a promising therapy for ARFID in school-age children. Challenges and strategies are discussed, including ways to address obstacles such as young age, comorbidities, and use of the virtual environment.

Protocol for a randomized clinical trial for Avoidant Restrictive Food Intake Disorder (ARFID) in low-weight youth.

Background Avoidant Restrictive Food Intake Disorder (ARFID) is an eating disorder recently added to the Diagnostic and Statistical Manual, 5th Edition (DSM-5) that involves nutritional, developmental, and/or psychosocial impairment, and often presents with a lack of interest in eating, sensory-related eating concerns, and/or fear of adverse consequences related to eating. There is limited evidence on treatments for ARFID, and in particular, treatments for children in the outpatient setting. Pilot data suggest that Family-Based Treatment (FBT) modified for ARFID is efficacious, and that improvements in parental self-efficacy may be the mechanism behind its success. This manuscript describes a study protocol seeking to confirm these preliminary findings through an adequately powered, randomized clinical trial (RCT). METHODS: This trial will randomize 100 children ages 6-12 years old who meet DSM-5 criteria for ARFID and their families to receive either 14 telehealth sessions of FBT-ARFID (n = 50) or a manualized Psychoeducational Motivation Therapy (PMT) treatment (n = 50), an individual therapy addressing the child's understanding of the problems ARFID is causing and promoting non-behavioral motivation and exploration of changing their eating patterns. Masked assessments will be conducted at baseline, one and two months within treatment, end-of-treatment, and six-month follow-up. Primary outcomes include change in body weight, parental self-efficacy, and parent feeding behaviors between baseline and end-of-treatment. CONCLUSIONS: The results of this RCT will advance our understanding of effective treatments for low-weight ARFID in youth.

Set-shifting among adolescents with bulimic spectrum eating disorders.

OBJECTIVE: Set-shifting difficulties are observed among adults with bulimia nervosa (BN). This study aimed to assess whether adolescents with BN and BN spectrum eating disorders exhibit set-shifting problems relative to healthy controls. METHODS: Neurocognitive data from 23 adolescents with BN were compared with those from 31 adolescents with BN-type eating disorder not otherwise specified and 22 healthy controls on various measures of set-shifting (Trail Making Task [shift task], Color-Word Interference, Wisconsin Card Sorting Test, and Brixton Spatial Anticipation Task). RESULTS: No significant differences in set-shifting tasks were found among groups (p >.35), and effect sizes were small (Cohen f < 0.17). CONCLUSIONS: Cognitive inflexibility may develop over time because of the eating disorder, although it is possible that there is a subset of individuals in whom early neurocognitive difficulty may result in a longer illness trajectory. Future research should investigate the existence of neurocognitive taxons in larger samples and use longitudinal designs to fully explore biomarkers and illness effects. TRIAL REGISTRATION: clinicaltrials.gov NCT00879151.

Experiences of mimicry in eating disorders.

BACKGROUND: People unknowingly mimic the behaviors of others, a process that results in feelings of affiliation. However, some individuals with eating disorders describe feeling "triggered" when mimicked. This study explores the effects of implicit non-verbal mimicry on individuals with a history of an eating disorder (ED-His) compared to healthy controls (HCs). METHOD: Women (N = 118, nED-His = 31; Mage = 21 years) participated in a laboratory task with a confederate trained to either discreetly mimic (Mimicry condition) or not mimic (No-Mimicry condition) the mannerisms of the participant. Participants rated the likability of the confederate and the smoothness of the interaction. RESULTS: Participants in the No-Mimicry condition rated the confederate as significantly more likable than in the Mimicry condition, and ED-His rated the confederate as more likable than HCs. ED-His in the Mimicry condition rated the interaction as less smooth than HCs, whereas this pattern was not found in the No-Mimicry condition. Among ED-His, longer disorder duration (≥ 3.87 years) was associated with less liking of a confederate who mimicked and more liking of a confederate who did not mimic. CONCLUSIONS: We discuss the implications of these findings for interpersonal therapeutic processes and group treatment settings for eating disorders. Our study on subtle, nonverbal mimicry revealed differences in social behavior for women with a history of an eating disorder compared to healthy women. For participants with an eating disorder history, a longer duration of illness was associated with a worse pattern of affiliation, reflected in lower liking of a mimicker. Further research on how diverging processes of affiliation may function to perpetuate the chronicity of eating disorders and implications for treatment is needed.

A mixed-methods approach to conceptualizing friendships in anorexia nervosa.

BACKGROUND: Individuals with anorexia nervosa have reported feelings of loneliness, social anhedonia, and interpersonal difficulties. This study sought to clarify the nature of interpersonal relationships in adults with anorexia, which may help improve existing interventions while also facilitating the attainment of something that might compete with the drive for thinness: friendships. METHODS: The present study used a mixed-methods approach to investigate friendship experiences in three groups: anorexia (n = 27), participants with a history of anorexia who are weight restored (n = 20), and healthy controls (n = 24). Thematic analysis was used to isolate the most prevalent themes that emerged from an open-ended interview of experiencing friendships in a subset of participants. Three self-report questionnaires investigating friendship valuation and attachment styles were also administered. RESULTS: 11 unique themes emerged in the data: social comparison, reciprocity, trust, fear of negative evaluation, perceived skills deficit, logistical barriers, reliability, identity issue, low interest, similarity, and conflict avoidance. Only 17% of those with anorexia reported experiencing friendships as positive, relative to 82% of healthy controls and 52% of weight restored participants. Lastly, on self-report measures, participants with anorexia reported greater reliance on themselves versus others, greater use of care-seeking behaviors, and more fear/anger at the thought of losing an attachment figure (p < .05 in all cases). CONCLUSION: Results suggest that individuals with anorexia have particular challenges which interfere with the formation and maintenance of friendships, such as viewing friendships negatively and struggling with social comparisons in friendships. Assessing and addressing barriers to intimacy may motivate those with anorexia to relinquish dangerous symptoms that maintain the illness.

Internal states and interoception along a spectrum of eating disorder symptomology.

OBJECTIVE: Recent studies on atypical interoceptive capabilities have focused on clinical populations, including anorexia nervosa[1,2]. The present exploratory study aims to characterize the influence of disordered eating symptomology on interoceptive capabilities in college students, a population for which dangerous dieting behaviors may emerge. METHOD: Ninety-nine participants were randomized to consume a blinded high calorie or low calorie midday shake. Participants reported frequency of eating disorder cognitions and behaviors; indicated changes in satiety, happiness, and energy pre- and post-consumption; and guessed the calories in their shake. Outcomes (perceived satiety, changes in mood, and caloric guess) were regressed on eating disorder symptoms scores, the high/low calorie shake condition, and the interaction between these predictors. RESULTS: Those randomized to receive the high calorie shake reported feeling fuller, but only when endorsing lower levels of eating concern. Those randomized to the high calorie shake reported greater post-meal happiness, but only at greater levels of eating concerns. Lastly, those with lower levels of eating restraint reported an expected positive association between level of fullness and calorie guess, but those with higher levels of eating restraint did not exhibit any relationship between perceived fullness and calorie guess. DISCUSSION: Results of this exploratory suggest that irregular eating habits (e.g., not eating a sufficient amount for lunch) may have direct consequences on interoceptive capabilities. Further, these capacities may be impacted by individual differences in eating concern and restraint. Preliminary findings suggest that impairment in deciphering visceral signals may be associated with the degree of eating disorder symptomology; such impairment may occur at lower levels of symptomatology than normative data would indicate.

Children's Beliefs about Pain: An Exploratory Analysis.

Functional abdominal pain (FAP) is one of the most common childhood medical complaints, associated with significant distress and impairment. Little is known about how children understand their pain. Do they attribute it to personal weakness? Do they perceive pain as having global impact, affecting a variety of activities? How do they cope with pain? We explored the pain beliefs of 5- to 9-year-old children with FAP using a novel Teddy Bear Interview task in which children answered questions about a Teddy bear's pain. Responses were analyzed quantitatively and qualitatively. Results indicate that the majority of young children with FAP are optimistic about pain outcomes. Children generated many types of coping strategies for Teddy's pain and adjusted their calibration of Teddy's pain tolerance dependent on the activity being performed. Early warning signs also emerged: a subset of children were pessimistic about Teddy's pain, and several children identified coping strategies that, while developmentally appropriate, could lead to excessive help seeking if not intervened upon (e.g., physician consultation and shot). The Teddy Bear Interview allows children to externalize their pain, making it a useful tool to access cognitive pain constructs in younger children. Thus, these findings highlight the importance of early intervention for childhood FAP.
