Posttraumatic stress disorder (PTSD) and complex PTSD in eating disorder treatment-seekers: Prevalence and associations with symptom severity.

Although childhood trauma and posttraumatic stress disorder (PTSD) have been well-researched in eating disorder epidemiology, prevalence rates are unavailable for complex PTSD (CPTSD). Under recently introduced ICD-11 criteria, individuals with CPTSD have both PTSD symptoms and additional disturbances in self-organization (DSO). Using ICD-11 criteria, this study aimed to determine the prevalence of PTSD and DSO symptoms, diagnostic rates of PTSD and CPTSD, and childhood trauma exposure in eating disorder treatment-seekers. Participants (N = 217) were individuals attending residential, partial hospitalization, and outpatient services who completed measures of eating disorder- and trauma-related symptoms and childhood adverse experiences. One third of participants reported PTSD symptoms, and over half reported DSO symptoms, with probable ICD-11 diagnostic rates of 3.8% for PTSD and 28.4% for CPTSD. CPTSD was significantly more prevalent than PTSD and more common in higher levels of care. Both PTSD and DSO symptom severity were positively correlated with eating disorder symptoms and impairment, rs = .285-.642. DSO symptom severity was a significant and unique explanatory factor of eating disorder severity and impairment. The findings highlight the prevalence of CPTSD in eating disorder populations and the association between DSO symptoms and eating psychopathology independent of PTSD symptoms. Implications are discussed for adjunct treatment approaches for individuals with comorbid eating disorders and PTSD or CPTSD.

Your Body Is Your Home: The feasibility of an intuitive eating intervention for early adolescents.

OBJECTIVE: Intuitive eating (IE) is an emerging health promotion framework which has shown promise in the prevention and early intervention of disordered eating (DE) behavior in adults. This study sought to extend this work by assessing the feasibility and preliminary efficacy of a 5-week IE intervention, "Your Body is Your Home," delivered in school classrooms for early adolescents aged 11-13. METHODS: The present study utilized a quasi-experimental design. Eligibility criteria were defined a priori and published in a registered protocol. Four classrooms (n = 128 student participants) were recruited into two streams, and self-report questionnaires were administered at pre-test, post-test, and 4-week follow-up. The questionnaires included the Intuitive Eating Scale for Early Adolescents (IES-2-EA), the Body Appreciation Scale (BAS-2), and the WHO Wellbeing Index (WHO-5). Linear mixed models were used to conduct preliminary efficacy testing. RESULTS: The results indicate that a brief classroom-based IE intervention is feasible and acceptable for both students and teaching staff; retention, fidelity, and attendance targets were achieved. Students and teachers rated all five sessions of the intervention as a highly feasible method of health promotion. Further, preliminary efficacy data suggest IE interventions aimed at early adolescents may be a feasible way of improving certain aspects of IE (p < .001) in male and female participants, and body appreciation (p < .001) in male participants. DISCUSSION: The study provides preliminary support for the implementation and evaluation of an IE intervention as part of school-based health promotion and offers preliminary effect size estimates for a larger-scale randomized trial. PUBLIC SIGNIFICANCE: Existing evidence suggests that IE may be a useful framework through which relationships with food and the body can be improved. The present study seeks to extend this work by adapting the framework for early adolescents (among whom the framework is not well understood) and examining feasibility, acceptability, and preliminary changes to several health and well-being metrics following a 5-week school-based intervention.

Eating behaviour, body image, and mental health: updated estimates of adolescent health, well-being, and positive functioning in Aotearoa New Zealand.

Introduction Body image dissatisfaction and its associated challenges have been related to poorer health outcomes among adolescents worldwide, including disordered eating behaviour, depression, and anxiety. However, current prevalence estimates of these issues in Aotearoa New Zealand or, relatedly, the estimates of positive attitudes and behaviours, such as intuitive eating and body appreciation are dated. Aim The primary aim of this paper was to provide updated estimates for a variety of constructs related to eating behaviours and body image, sourced from a diverse range of early adolescent participants. Methods For this report, a brief online survey was advertised to adolescents throughout Aotearoa New Zealand (n = 893) via school and community noticeboards. Results Approximately one-in-three male participants and one-in-two female participants reported body image dissatisfaction. One in four participants reported clinically significant symptoms of depression and anxiety. Discussion Given such issues, there is clearly still much progress to be made in advancing positive health among early adolescents. Identifying potentially protective constructs such as intuitive eating and body appreciation may offer guidance into the best targets for prevention and early intervention.

Intuitive Eating Scale-2-EA: Psychometric properties and factor structure of the adapted IES-2 for early adolescents.

PURPOSE: Intuitive Eating (IE) is an approach to eating characterised by attunement to intrinsic cues, and using those cues to guide behaviours related to food and eating. Tylka and Kroon Van Diest's (2008) Intuitive Eating Scale (IES-2) is well-validated in adults, but not yet among early adolescents. The current study was designed to adapt and validate a version suited for use in early adolescence (IES-2-EA). METHODS: Data collected from two independent samples of adolescents aged 11 to 13 (N = 471) were structurally examined using exploratory factor analysis (EFA), with a subsequent confirmatory factor analysis (CFA) to confirm hypothesised model fit. Relationships between scores on the IES-2-EA and validated measures of actual-ideal body size discrepancy, body appreciation, interoceptive awareness, and psychological distress were also examined. RESULTS: The adapted 17-item IES-2-EA had a three-factor structure with several key differences from the original version developed for adults. Moderate-to-strong correlations were found between scores on the IES-2-EA, body appreciation, interoceptive awareness, actual-ideal body size discrepancy, and psychological distress in the first sample of adolescents (n = 245). Secondary CFA showed good model fit in the second sample of adolescents (n = 226). CONCLUSION: The IES-2-EA is well-suited to measure intuitive eating behaviour among early adolescents. The 17 items reflect a three-component structure similar to that seen in adults completing the IES-2. These early data suggest the adapted IES-2-EA has evidence of reliability and validity; it may be an effective measure for research and clinical use.

Outcomes of intuitive eating interventions: a systematic review and meta-analysis.

Intuitive eating (IE) is an approach to health promotion that fosters a positive relationship with food and the body. The objective of this review was to aggregate and analyse the literature on IE interventions, thereby offering an early investigation of methodological approaches to intervention. This review was conducted in accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA) guidelines. Searching was conducted in four electronic databases. Studies were eligible for inclusion if they delivered an IE intervention and used the Intuitive Eating Scale (IES). Nine studies were included in this review. Six were eligible for meta-analysis, though only outcomes on the IES were examined; all other measures were examined individually. All interventions led to improvements on measures of IE, with a large pooled effect size (1.50 [1.15, 1.85]) and positive changes on a variety of other outcomes relating to health. This pattern preliminarily suggests that IE interventions change psychological processes as intended and can be useful in promoting health behaviour. The present review offers a synthesis of existing approaches to IE interventions and an evaluation of which specific variants appear to be more effective. This paper provides a basis upon which future interventions can be developed to improve approaches to psychoeducation.Clinical ImplicationsInterventions contributed to improvements in measures of IE lasting up to 6 months.Interventions contributed to positive changes on outcomes such as quality of life, body image, and body appreciation.Self-management through IE-based interventions may be feasible and effective.

Emotion Dysregulation and Eating Disorder Symptoms: Examining Distinct Associations and Interactions in Adolescents.

Emotion dysregulation has been posited as a key transdiagnostic factor of mental health difficulties, including eating disorders. However, how this transdiagnostic factor interacts with the disorder-specific factor of weight and shape concerns remains unclear. The current study examined whether emotion dysregulation is associated with eating disorder behaviors over and above the association between weight and shape concerns and whether these two factors interacted. The current study used data from two samples, a community sample of high school students (n = 2699), and a clinical sample of adolescents receiving outpatient treatment for an eating disorder (n = 149). Participants completed self-report measures on their eating behaviors, weight/shape concerns, and emotion dysregulation. Findings showed that emotion dysregulation had a unique association with engaging in binge eating and purging (community sample only). Weight and shape concerns were found to have a unique association with engaging in binge eating, fasting, purging, and driven exercise (community sample only). Additionally, weight and shape concerns moderated the association between emotion dysregulation and the probability of engaging in binge eating and driven exercise, whereby the strongest association between emotion dysregulation and these behaviors were observed among adolescents with the lowest levels of weight and shape concerns. Regarding the frequency of eating disorder behaviors, emotion dysregulation had a unique association with severity of binge eating and fasting. Weight and shape concerns were uniquely associated with severity of fasting and driven exercise (community sample only). Findings suggest that emotion dysregulation is a distinct factor of eating disorder behaviors among adolescents.

Intuitive Eating Scale-2: psychometric properties and clinical norms among individuals seeking treatment for an eating disorder in private practice.

PURPOSE: Intuitive Eating (IE) is an approach to eating designed to facilitate a positive relationship with food. Its use in clinical settings and in the community is rapidly growing in popularity. The Intuitive Eating Scale 2 (IES-2) is a widely used measure that indexes intuitive eating motivations and behaviour, however evidence of its validity in populations with clinical eating disorders remains scarce. The objective of the proposed study was thus to evaluate the factor structure of the IES-2 in a large sample of individuals seeking treatment for eating disorders in private practice. METHODS: Data collected from 569 women and men aged 12-68 years seeking treatment for an eating disorder in one of eight specialist private outpatient eating disorder clinics were examined using confirmatory factor analysis (CFA). Relationships between IES-2 scores and measures of psychopathology were also examined. RESULTS: Results were relatively consistent with the purported four-factor structure of the IES-2. The measure displayed strong construct validity and good internal consistency. Scores on the IES-2 were inversely associated with scores of depression, anxiety, and disordered eating, providing evidence for divergent validity of the measure. Clinical norms are provided for anorexia nervosa (AN) spectrum disorders and bulimia nervosa (BN) spectrum disorders, as well as for the clinical sample as a whole. CONCLUSION: Findings suggest that the IES-2 may be an appropriate measure for evaluating behaviours relating to IE in community outpatient eating disorder settings, and provide further evidence for the association between IE and positive health outcomes. LEVEL OF EVIDENCE: III, evidence obtained from well-designed cohort or case-control analytic studies.

Exploring alternatives for adolescent anorexia nervosa: adolescent and parent treatment (APT) as a novel intervention prospect.

Recovery and remission rates of adolescent anorexia nervosa (AN) following Family Based Treatment (FBT) have seen a relative decline over recent years. While reasonably successful in achieving physical recovery (i.e. weight restoration), both empirical and anecdotal accounts highlight a lack of attention to the psychological recovery of the adolescent within manualised FBT. As such, there is a need for innovation to explore treatment variations and alternatives for the proportion of adolescents with AN who do not respond favourably to this first-line treatment. This paper introduces a new treatment framework to the field for clinical consideration and empirical assessment. Adolescent and Parent Treatment (APT) for adolescent AN draws from both family-based and individual treatment models, applying a developmental lens. APT attends to physical and psychological recovery simultaneously and from the start of treatment, with capacity to tailor individual psychological modules to the adolescent formulation. While clearly in its infancy, APT provides an exciting new avenue for exploration within the field, as we seek new avenues to support young people and their families to effectively combat this deadly illness.

ANZAED practice and training standards for mental health professionals providing eating disorder treatment.

INTRODUCTION: The Australia & New Zealand Academy for Eating Disorders (ANZAED) recently developed general principles and clinical practice standards recommended for mental health clinicians and dietitians providing treatment for people with eating disorders. Separate mental health practice and training standards were then devised as a foundation for strengthening the workforce and providing guidance to professional training programs and service providers on the minimal standards required for practice in the eating disorder field. RECOMMENDATIONS: The present recommendations for mental health professionals providing eating disorder treatment describe the following practice and training standards: eating disorder treatment foundations (including co-ordination of services, establishing a positive therapeutic alliance, professional responsibility and knowledge of levels of care), assessment, diagnosis, intervention (including evidence-based intervention, managing psychiatric risk and managing co-morbid mental health problems), and monitoring and evaluation. CONCLUSIONS: Further work is required to disseminate these standards to clinicians providing services across Australia to people with eating disorders, and to support adherence in the clinic room where they can translate to improved outcomes for clients. Pathways to supporting adherence include expert supervision of practice, incorporation in training and supervised practice in university settings, and support with checklists that can be used by consumers and referring professionals.

ANZAED eating disorder treatment principles and general clinical practice and training standards.

INTRODUCTION: Eating disorders are complex to manage, and there is limited guidance around the depth and breadth of knowledge, skills and experience required by treatment providers. The Australia & New Zealand Academy for Eating Disorders (ANZAED) convened an expert group of eating disorder researchers and clinicians to define the clinical practice and training standards recommended for mental health professionals and dietitians providing treatment for individuals with an eating disorder. General principles and clinical practice standards were first developed, after which separate mental health professional and dietitian standards were drafted and collated by the appropriate members of the expert group. The subsequent review process included four stages of consultation and document revision: (1) expert reviewers; (2) a face-to-face consultation workshop attended by approximately 100 health professionals working within the sector; (3) an extensive open access online consultation process; and (4) consultation with key professional and consumer/carer stakeholder organisations. RECOMMENDATIONS: The resulting paper outlines and describes the following eight eating disorder treatment principles: (1) early intervention is essential; (2) co-ordination of services is fundamental to all service models; (3) services must be evidence-based; (4) involvement of significant others in service provision is highly desirable; (5) a personalised treatment approach is required for all patients; (6) education and/or psychoeducation is included in all interventions; (7) multidisciplinary care is required and (8) a skilled workforce is necessary. Seven general clinical practice standards are also discussed, including: (1) diagnosis and assessment; (2) the multidisciplinary care team; (3) a positive therapeutic alliance; (4) knowledge of evidence-based treatment; (5) knowledge of levels of care; (6) relapse prevention; and (7) professional responsibility. CONCLUSIONS: These principles and standards provide guidance to professional training programs and service providers on the development of knowledge required as a foundation on which to build competent practice in the eating disorder field. Implementing these standards aims to bring treatment closer to best practice, and consequently improve treatment outcomes, reduce financial cost to patients and services and improve patient quality of life.

Cognitive inflexibility and over-attention to detail: The Italian validation of the DFlex Questionnaire in patients with eating disorders.

OBJECTIVE: Cognitive inflexibility and over-attention to detail are two cognitive styles common to eating disorders (ED) and other psychopathologies characterized by rigid perfectionism. Despite many options to assess the above styles, the only self-report tool that simultaneously permits their specific assessment is the Detail and Flexibility Questionnaire (DFlex), originally developed to investigate the ED domain. The aim of this study was to validate the Italian version of the DFlex. METHOD: 170 patients (149 females) with ED and 148 controls (100 females) completed the Italian version of the DFlex. RESULTS: A Confirmatory Factor Analysis showed that the two-factor model originally proposed in the literature was a good fit to the data. Item factor loadings were largely equivalent across clinical and control groups, with intercept distributions showing higher values for the clinical group compared to controls. Both DFlex subscales showed good internal reliability and were able to predict membership to the group condition. CONCLUSIONS: The DFlex is a reliable tool for investigation in the ED population. However, because DFlex items do not explicitly assess food and body shape domains, it is possible to extend its use to other psychopathologies characterized by rigid perfectionism. We propose the use of the DFlex in research and clinical practice as a useful tool for better understanding patients' cognitive functioning and in order to support treatment planning.

Feasibility of group Cognitive Remediation Therapy in an adult eating disorder day program in New Zealand.

OBJECTIVE: To explore the feasibility of integrating group Cognitive Remediation Therapy (gCRT) into an eating disorder day program in Auckland, New Zealand. METHOD: A consecutive series of 28 patients took part over an 8-month period in the context of a service audit. Main outcome measures were the Detail and Flexibility Questionnaire (DFlex) and qualitative feedback from patients. RESULTS: Significant shifts in self-report inefficient cognitive style were observed pre/post gCRT with large effect sizes (Cohen's dav) for both cognitive rigidity and attention to detail outcomes. Patient feedback was positive, with themes of enjoyment, increased insight, and positive social interaction/esteem boosting in the context of the group emerging. CONCLUSIONS: Support for the acceptability, adaptation, expansion, practicality, and limited-efficacy testing of gCRT in an Australasian day program setting has been found, suggesting integration of this module into existing day treatment programs is merited. Larger scale trials may help delineate the clinical characteristics of good responders.

Video evidence that parenting methods predict which infants develop long night-time sleep periods by three months of age.

Aim To examine two hypotheses about the longitudinal relationship between night-time parenting behaviours in the first few postnatal weeks and infant night-time sleep-waking at five weeks, three months and six months of age in normal London home environments. BACKGROUND: Most western infants develop long night-time sleep periods by four months of age. However, around 20-30% of infants in many countries continue to sleep for short periods and cry out on waking in the night: the most common type of infant sleep behaviour problem. Preventive interventions may help families and improve services. There is evidence that 'limit-setting' parenting, which is common in western cultures, supports the development of settled infant night-time behaviour. However, this evidence has been challenged. The present study measures three components of limit-setting parenting (response delay, feeding interval, settling method), examines their stability, and assesses the predictive relationship between each of them and infant sleep-waking behaviours. METHODS: Longitudinal observations comparing a General-Community (n=101) group and subgroups with a Bed-Sharing (n=19) group on infra-red video, diary and questionnaire measures of parenting behaviours and infant feeding and sleep-waking at night. Findings Bed-Sharing parenting was highly infant-cued and stable. General-Community parenting involved more limit-setting, but was less stable, than Bed-Sharing parenting. One element of General-Community parenting - consistently introducing a short interval before feeding - was associated with the development of longer infant night-time feed intervals and longer day-time feeds at five weeks, compared with other General-Community and Bed-Sharing infants. Twice as many General-Community infants whose parents introduced these short intervals before feeding in the early weeks slept for long night-time periods at three months of age on both video and parent-report measures, compared with other General-Community and Bed-Sharing infants. The findings' implications for our understanding of infant sleep-waking development, parenting programmes, and for practice and research, are discussed.

Central Coherence in Eating Disorders: A Synthesis of Studies Using the Rey Osterrieth Complex Figure Test.

BACKGROUND: Large variability in tests and differences in scoring systems used to study central coherence in eating disorders may lead to different interpretations, inconsistent findings and between study discrepancies. This study aimed to address inconsistencies by collating data from several studies from the same research group that used the Rey Osterrieth Complex Figure Test (Rey Figure) in order to produce norms to provide benchmark data for future studies. METHOD: Data was collated from 984 participants in total. Anorexia Nervosa, Bulimia Nervosa, recovered Anorexia Nervosa, unaffected family members and healthy controls were compared using the Rey Figure. RESULTS: Poor global processing was observed across all current eating disorder sub-groups and in unaffected relatives. There was no difference in performance between recovered AN and HC groups. CONCLUSIONS: This is the largest dataset reported in the literature and supports previous studies implicating poor global processing across eating disorders using the Rey Figure. It provides robust normative data useful for future studies.

Descriptive figures for differences in parenting and infant night-time distress in the first three months of age.

Aim To provide descriptive figures for infant distress and associated parenting at night in normal London home environments during the first three months of age. BACKGROUND: Most western infants develop long night-time sleep periods by four months of age. However, 30% of infants in many countries sleep for short periods and cry out on waking in the night: the most common type of infant sleep behaviour problem. Preventive interventions may help families and improve services. There is evidence that 'limit-setting' parenting, which is common in western cultures, supports the development of settled infant night-time behaviour. However, a recent review has challenged this and argued that this form of parenting risks distressing infants. This study describes limit-setting parenting as practiced in London, compares it with 'infant-cued' parenting and measures the associated infant distress. METHODS: Longitudinal infrared video, diary and questionnaire observations comparing a General-Community (n=101) group and subgroups with a Bed-Sharing (n=19) group on measures of infant and parenting behaviours at night. Findings General-Community parents took longer to detect and respond to infant waking and signalling, and to begin feeding, compared with the highly infant-cued care provided by Bed-Sharing parents. The average latency in General-Community parents' responding to infant night-time waking was 3.5 min, during which infants fuss/cried for around 1 min. Compared with Bed-Sharing parenting, General-Community parenting was associated with increased infant distress of around 30 min/night at two weeks, reducing to 12 min/night by three months of age. However, differences in infant distress between General-Community subgroups adopting limit-setting versus infant-cued parenting were not large or statistically significant at any age. The figures provide descriptive evidence about limit-setting parenting which may counter some doubts about this form of parenting and help parents and professionals to make choices.

Video Evidence That London Infants Can Resettle Themselves Back to Sleep After Waking in the Night, as well as Sleep for Long Periods, by 3 Months of Age.

OBJECTIVE: Most infants become settled at night by 3 months of age, whereas infants not settled by 5 months are likely to have long-term sleep-waking problems. We assessed whether normal infant development in the first 3 months involves increasing sleep-period length or the ability to resettle autonomously after waking in the night. METHODS: One hundred one infants were assessed at 5 weeks and 3 months of age using nighttime infrared video recordings and parental questionnaires. RESULTS: The clearest development was in sleep length; 45% of infants slept continuously for ≥5 hours at night at 3 months compared with 10% at 5 weeks. In addition, around a quarter of infants woke and resettled themselves back to sleep in the night at each age. Autonomous resettling at 5 weeks predicted prolonged sleeping at 3 months suggesting it may be a developmental precursor. Infants reported by parents to sleep for a period of 5 hours or more included infants who resettled themselves and those with long sleeps. Three-month olds fed solely breast milk were as likely to self-resettle or have long sleep bouts as infants fed formula or mixed breast and formula milk. CONCLUSIONS: Infants are capable of resettling themselves back to sleep in the first 3 months of age; both autonomous resettling and prolonged sleeping are involved in "sleeping through the night" at an early age. Findings indicate the need for physiological studies of how arousal, waking, and resettling develop into sustained sleeping and of how environmental factors support these endogenous and behavioral processes.

Is attention to detail a similarly strong candidate endophenotype for anorexia nervosa and bulimia nervosa?

OBJECTIVES: To investigate whether attention to detail is a similarly strong candidate endophenotype of anorexia (AN) and bulimia nervosa (BN), and to explore the incidence and clinical correlates of attention to detail. METHODS: A total of 266 women (including AN, BN, recovered AN, unaffected sisters of AN/BN & control women) undertook a thorough clinical assessment and were administered two neuropsychological measures of attention to detail (Group Embedded Figure Test; Rey-Osterrieth Complex Figure). RESULTS: Superior attention to detail was found across all AN groups including recovered AN and unaffected AN sisters. Those with BN and their unaffected sisters showed a profile more consistent with poor global integration. The combined effect of superior attention to detail and poor global integration ("weak coherence") was present in 42.3% of active cases and corresponded with a more severe illness, elevated obsessive-compulsive symptoms, and a higher likelihood of comorbid clinical anxiety and self-harm. CONCLUSIONS: Attention to detail is a stronger candidate endophenotype of AN compared to BN, where poor global integration may be more relevant. The unique contribution of both aspects of weak coherence (superior attention to detail/poor global integration) requires further exploration and understanding in both eating disorders. Integrating cognitive remediation of these traits into treatment for the subset of patients it is relevant for may improve outcome.

Poor cognitive flexibility in eating disorders: examining the evidence using the Wisconsin Card Sorting Task.

BACKGROUND: People with eating disorders (ED) frequently present with inflexible behaviours, including eating related issues which contribute to the maintenance of the illness. Small scale studies point to difficulties with cognitive set-shifting as a basis. Using larger scale studies will lend robustness to these data. METHODOLOGY/PRINCIPAL FINDINGS: 542 participants were included in the dataset as follows: Anorexia Nervosa (AN) n = 171; Bulimia Nervosa (BN) n = 82; Recovered AN n = 90; Healthy controls (HC): n = 199. All completed the Wisconsin Card Sorting Task (WCST), an assessment that integrates multiple measurement of several executive processes concerned with problem solving and cognitive flexibility. The AN and BN groups performed poorly in most domains of the WCST. Recovered AN participants showed a better performance than currently ill participants; however, the number of preservative errors was higher than for HC participants. CONCLUSIONS/SIGNIFICANCE: There is a growing interest in the diagnostic and treatment implications of cognitive flexibility in eating disorders. This large dataset supports previous smaller scale studies and a systematic review which indicate poor cognitive flexibility in people with ED.
