A multi-centre cohort study of short term outcomes of hospital treatment for anorexia nervosa in the UK

BackgroundIndividual, family and service level characteristics and outcomes are described for adult and adolescent patients receiving specialist inpatient or day patient treatment for anorexia nervosa (AN). Potential predictors of treatment outcome are explored.MethodAdmission and discharge data were collected from patients admitted at 14 UK hospital treatment units for AN over a period of three years (adult units N = 12; adolescent N = 2) (patients N = 177).ResultsOne hundred and seventy-seven patients with a severe and enduring illness with wide functional impairment took part in the study. Following inpatient care, physical improvement was moderate/good with a large increase in BMI, although most patients continued to have a clinical level of eating disorder symptoms at discharge. The potentially modifiable predictors of outcome included confidence to change, social functioning and carer expressed emotion and control.ConclusionsOverall, the response to inpatient treatment was modest particularly in the group with a severe enduring form of illness. Adolescents had a better response. Although inpatient treatment produces an improvement in physical health there was less improvement in other eating disorder and mood symptoms. As predicted by the carer interpersonal maintenance model, carer behaviour may influence the response to inpatient care, as may improved social functioning and confidence to change.

Caregiving and coping in carers of people with anorexia nervosa admitted for intensive hospital care

OBJECTIVE The aim of the study was to examine how carers cope practically and emotionally with caring for individuals with anorexia nervosa who require intensive hospital care. METHOD This study explores objective burden (time spent with caregiving and number of tasks), subjective burden (psychological distress), and social support in a sample of parents (n = 224) and partners (n = 28) from a consecutive series of patients (n = 178) admitted to inpatient units within the United Kingdom. RESULTS Most time was spent providing emotional support and less with practical tasks. Time spent with caregiving was associated with carer distress and was fully mediated by carer burden. This was ameliorated by social support. Partners received minimal support from others, and we found similar levels of burden and distress for mothers and partners. DISCUSSION The data indicate that professional and social support alleviates carer distress and may be of particular value for partners who are more isolated than parents. The data also suggest that time spent with practical support may be of more value than emotional support.

Interventions for caregivers of someone with an eating disorder: A meta-analysis

OBJECTIVE A variety of interventions have been developed for caregivers of people with an eating disorder either to help them cope with the burden and distress that commonly accompanies this role or to make them more effective at providing support. The aim of the study is to perform a meta-analysis of quantitative studies that have described the impact of these interventions on caregivers. METHOD Electronic databases were searched between September 2001 and September 2013. Thirteen studies were finally selected for inclusion. Pooled effect size estimates were summarized. Meta-regressions were used to determine whether type of intervention, team, measure used or risk of bias were effect modifiers of the relationship. We also summarized the content and form (amount of professional help) of the interventions. RESULTS Most interventions produced a moderate sized reduction in carer distress and a small/moderate reduction in carer burden and expressed emotion post treatment and these changes were maintained over follow-up. DISCUSSION Carer distress, burden and expressed emotion can be reduced by a variety of psychoeducational interventions and these changes are sustainable over time. The interventions themselves are easy to disseminate and deliver.

An examination of autism spectrum traits in adolescents with anorexia nervosa and their parents

BackgroundThere may be a link between anorexia nervosa and autism spectrum disorders. The aims of this study were to examine whether adolescents with anorexia nervosa have autism spectrum and/or obsessive-compulsive traits, how many would meet diagnostic criteria for autism spectrum disorder, and whether these traits are shared by parents.MethodsA total of 150 adolescents receiving outpatient treatment for anorexia nervosa or subthreshold anorexia nervosa and their parents completed the autism spectrum disorder and eating disorder sections of the Development and Well-being Assessment. Patients also completed the Children Yale-Brown Obsessive-Compulsive Scale and other measures of psychiatric morbidity, and parents completed the short Autism Quotient and Obsessive-Compulsive Inventory Revised.ResultsAdolescents with anorexia nervosa had a below average social aptitude (19% below cut-off) and high levels of peer relationship problems (39% above cut-off) and obsessive-compulsive symptoms (56% above cut-off). Six cases (4%, all females) were assigned a possible (n = 5) or definite (n = 1) diagnosis of autism spectrum disorder. Parental levels of autism spectrum and obsessive-compulsive traits were within the normal range.ConclusionsThis study suggests that adolescents with anorexia nervosa have elevated levels of autism spectrum traits, obsessive-compulsive symptoms, and a small proportion fulfil diagnostic criteria for a probable autism spectrum disorder. These traits did not appear to be familial. This comorbidity has been associated with a poorer prognosis. Therefore, adaptation of treatment for this subgroup may be warranted.Trial registrationControlled-trials.com: ISRCTN83003225. Registered on 29 September 2011.

Emotional Processing, Recognition, Empathy and Evoked Facial Expression in Eating Disorders: An Experimental Study to Map Deficits in Social Cognition

Background Difficulties in social cognition have been identified in eating disorders (EDs), but the exact profile of these abnormalities is unclear. The aim of this study is to examine distinct processes of social-cognition in this patient group, including attentional processing and recognition, empathic reaction and evoked facial expression in response to discrete vignettes of others displaying positive (i.e. happiness) or negative (i.e. sadness and anger) emotions. Method One hundred and thirty-eight female participants were included in the study: 73 healthy controls (HCs) and 65 individuals with an ED (49 with Anorexia Nervosa and 16 with Bulimia Nervosa). Self-report and behavioural measures were used. Results Participants with EDs did not display specific abnormalities in emotional processing, recognition and empathic response to others’ basic discrete emotions. However, they had poorer facial expressivity and a tendency to turn away from emotional displays. Conclusion Treatments focusing on the development of non-verbal emotional communication skills might be of benefit for patients with EDs.

Clinical effectiveness of a skills training intervention for caregivers in improving patient and caregiver health following in-patient treatment for severe anorexia nervosa: pragmatic randomised controlled trial

Background Families express a need for information to support people with severe anorexia nervosa. Aims To examine the impact of the addition of a skills training intervention for caregivers (Experienced Caregivers Helping Others, ECHO) to standard care. Method Patients over the age of 12 (mean age 26 years, duration 72 months illness) with a primary diagnosis of anorexia nervosa and their caregivers were recruited from 15 in-patient services in the UK. Families were randomised to ECHO (a book, DVDs and five coaching sessions per caregiver) or treatment as usual. Patient (n=178) and caregiver (n=268) outcomes were measured at discharge and 6 and 12 months after discharge. Results Patients with caregivers in the ECHO group had reduced eating disorder psychopathology (EDE-Q) and improved quality of life (WHO-Quol; both effects small) and reduced in-patient bed days (7–12 months post-discharge). Caregivers in the ECHO group had reduced burden (Eating Disorder Symptom Impact Scale, EDSIS), expressed emotion (Family Questionnaire, FQ) and time spent caregiving at 6 months but these effects were diminished at 12 months. Conclusions Small but sustained improvements in symptoms and bed use are seen in the intervention group. Moreover, caregivers were less burdened and spent less time providing care. Caregivers had most benefit at 6 months suggesting that booster sessions, perhaps jointly with the patients, may be needed to maintain the effect. Sharing skills and information with caregivers may be an effective way to improve outcomes. This randomised controlled trial (RCT) was registered with Current Controlled Trials ISRCTN06149665.

Emotional Processing of Infants Displays in Eating Disorders

Aim The aim of this study is to examine emotional processing of infant displays in people with Eating Disorders (EDs). Background Social and emotional factors are implicated as causal and maintaining factors in EDs. Difficulties in emotional regulation have been mainly studied in relation to adult interactions, with less interest given to interactions with infants. Method A sample of 138 women were recruited, of which 49 suffered from Anorexia Nervosa (AN), 16 from Bulimia Nervosa (BN), and 73 were healthy controls (HCs). Attentional responses to happy and sad infant faces were tested with the visual probe detection task. Emotional identification of, and reactivity to, infant displays were measured using self-report measures. Facial expressions to video clips depicting sad, happy and frustrated infants were also recorded. Results No significant differences between groups were observed in the attentional response to infant photographs. However, there was a trend for patients to disengage from happy faces. People with EDs also reported lower positive ratings of happy infant displays and greater subjective negative reactions to sad infants. Finally, patients showed a significantly lower production of facial expressions, especially in response to the happy infant video clip. Insecure attachment was negatively correlated with positive facial expressions displayed in response to the happy infant and positively correlated with the intensity of negative emotions experienced in response to the sad infant video clip. Conclusion People with EDs do not have marked abnormalities in their attentional processing of infant emotional faces. However, they do have a reduction in facial affect particularly in response to happy infants. Also, they report greater negative reactions to sadness, and rate positive emotions less intensively than HCs. This pattern of emotional responsivity suggests abnormalities in social reward sensitivity and might indicate new treatment targets.

Disseminating skills to carers of people with eating disorders: an examination of treatment fidelity in lay and professional carer coaches

Family members of people with eating disorders (EDs) have high levels of stress and can use maladaptive methods of coping. We have developed an intervention, using motivational interviewing (MI) strategies that trains lay and professional carer coaches (CCs) to support carers of adolescents with EDs to use more adaptive coping procedures. The aim of this study is to measure treatment integrity in coaches with either academic or lived experience. Eleven coaches were trained and supervised by an expert trainer and an ‘expert by experience’ trainer. Six of the coaches had prior training in clinical work and/or psychology and five had personal experience of supporting a loved one with an ED. Two audio-taped sessions (Sessions 3 and 7) from each family coached (n = 22) were assessed for fidelity to MI. Half the sessions (50% n = 11) had a Motivational Interviewing Treatment Integrity global score above the suggested cut-off for recommended competency. Prior clinical training was related to higher treatment fidelity and experiential training (having coached a greater number of families) improved treatment fidelity in the lay carer group. These preliminary findings suggest that: “lay CCs” can be trained to deliver an intervention based on MI. Further exploration of a more effective means of training, monitoring and supervision is required to maximise the quality of the intervention.

Confirmatory factor analysis for two questionnaires of caregiving in eating disorders.

Objective: Caring for someone diagnosed with an eating disorder (ED) is associated with a high level of burden and psychological distress which can inadvertently contribute to the maintenance of the illness. The Eating Disorders Symptom Impact Scale (EDSIS) and Accommodation and Enabling Scale for Eating Disorders (AESED) are self-report scales to assess elements of caregiving theorised to contribute to the maintenance of an ED. Further validation and confirmation of the factor structures for these scales are necessary for rigorous evaluation of complex interventions which target these modifiable elements of caregiving. Method: EDSIS and AESED data from 268 carers of people with anorexia nervosa (AN), recruited from consecutive admissions to 15 UK inpatient or day patient hospital units, were subjected to confirmatory factor analysis to test model fit by applying the existing factor structures: (a) four-factor structure for the EDSIS and (b) five-factor structure for the AESED. Results: Confirmatory factor analytic results support the existing four-factor and five-factor structures for the EDSIS and the AESED, respectively. Discussion: The present findings provide further validation of the EDSIS and the AESED as tools to assess modifiable elements of caregiving for someone with an ED.

An examination of the clinical outcomes of adolescents and young adults with broad autism spectrum traits and autism spectrum disorder and anorexia nervosa: A multi centre study

OBJECTIVES To compare the clinical outcomes of adolescents and young adults with anorexia nervosa (AN) comorbid with broad autism spectrum disorder (ASD) or ASD traits. METHOD The developmental and well-being assessment and social aptitude scale were used to categorize adolescents and young adults with AN (N = 149) into those with ASD traits (N = 23), and those who also fulfilled diagnostic criteria for a possible/probable ASD (N = 6). We compared both eating disorders specific measures and broader outcome measures at intake and 12 months follow-up. RESULTS Those with ASD traits had significantly more inpatient/day-patient service use (p = .015), as well as medication use (p < .001) at baseline. Both groups had high social difficulties and poorer global functioning (strengths and difficulties questionnaire) at baseline, which improved over time but remained higher at 12 months in the ASD traits group (p = .002). However, the improvement in eating disorder symptoms at 12 months was similar between groups with or without ASD traits. Treatment completion rates between AN only and ASD traits were similar (80.1 vs. 86.5%). DISCUSSION Adolescents with AN and ASD traits show similar reductions in their eating disorder symptoms. Nevertheless, their social difficulties remain high suggesting that these are life-long difficulties rather than starvation effects.
