Coutinho BDMC, Pariz CG, Krahe TE, Mograbi DC. Are you how you eat? Aspects of self-awareness in eating disorders. PERSONALITY NEUROSCIENCE 2024; 7:e9. [PMID: 38826820 PMCID: PMC11140494 DOI: 10.1017/pen.2024.2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 03/15/2024] [Accepted: 04/13/2024] [Indexed: 06/04/2024]
Abstract
Eating disorders (ED) are severe psychiatric disorders characterized by dysfunctional behaviors related to eating or weight control, with profound impacts on health, quality of life, and the financial burden of affected individuals and society at large. Given that these disorders involve disturbances in self-perception, it is crucial to comprehend the role of self-awareness in their prevalence and maintenance. This literature review presents different self-awareness processes, discussing their functioning across different levels of complexity. By deconstructing this concept, we can gain a better understanding of how each facet of self and personality relates to the symptoms of these disorders. Understanding the absence or impairment of self-awareness in ED holds significant implications for diagnosis, treatment, and overall management. By recognizing and comprehending the characteristics of self-awareness, clinicians can develop tailored interventions and evidence-based treatments for individuals with ED. Furthermore, this narrative review underscores the importance of considering temperament and personality factors in the context of ED, as temperament traits and personality characteristics may interact with self-awareness processes, influencing the development and maintenance of ED. Ultimately, the results highlight the pressing need for further research on the development of effective interventions and support strategies grounded in the aspects of self-awareness mechanisms for individuals affected by these disorders.

Sternheim LC, Bijsterbosch JM, Wever MCM, van Elburg AA, Frank GKW. Examining anxious temperament in anorexia nervosa: Behavioural inhibition and intolerance of uncertainty and their contribution to trait anxiety in adolescents with anorexia nervosa. J Affect Disord 2024; 348:116-123. [PMID: 38110154 DOI: 10.1016/j.jad.2023.12.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 12/06/2023] [Accepted: 12/13/2023] [Indexed: 12/20/2023]
Abstract
BACKGROUND Anorexia nervosa (AN) is a serious and complex psychiatric disorder yet treatment results are suboptimal. Insight into the etiology of this illness is much needed. Research highlights the implication of anxiety-related traits in the development and maintenance of AN. This study investigates firstly, behavioural inhibition and intolerance for uncertainty (IU) in adolescents with and without AN, and secondly relations between these traits. METHODS In a cross-sectional study, 165 adolescent girls (AN = 94, HC = 71) completed questionnaires measuring behavioural inhibition, IU and trait anxiety. ANOVAs tested differences between AN and HC groups, and mediation models with IU as a mediator between behavioural inhibition and trait anxiety were run. RESULTS AN adolescents reported significantly higher levels of behavioural inhibition, IU and trait anxiety compared to their peers. In both AN and HC, a direct and a total effect of behavioural inhibition on trait anxiety was found. However, only in the AN group IU partially mediated the relation between behavioural inhibition and trait anxiety. LIMITATIONS Data is cross-sectional and longitudinal studies are required. A mean illness duration of nearly 2 years may mean early effects of malnourishment and habituation and future studies should include patients with shorter illness duration. CONCLUSIONS Results highlight that behavioural inhibition and IU may contribute to anxiety in AN whilst their peers may have developed better executive and social-emotional skills to manage uncertainty. Adolescents with AN may benefit from interventions targeting behavioural inhibition and IU.

Abstract
BACKGROUND the mental health of students was particularly affected by the COVID-19 pandemic. The present study therefore examined the relationships between anxiety and depressive symptoms, eating-related problems, coping, fear of COVID-19, and intolerance of uncertainty. METHODS 2139 French students of 54 universities were recruited in the different regions of France during a French lockdown (between 21 April and 3 May 2021). Six variables were measured: fear of COVID-19, intolerance of uncertainty, coping, anxiety and depressive symptoms, and eating-related problems. To explore the directions of the relationships between our variables of interest, we calculated a directed acyclic graph. RESULTS our data highlighted the central roles of intolerance of uncertainty in students' anxiety and depressive symptoms, and the direct role of prospective intolerance of uncertainty on eating-related problems. CONCLUSIONS these findings indicate that intolerance of uncertainty should be targeted by interventions designed to help students with high levels of anxiety, depressive symptoms, and/or eating-related problems.

Abstract
OBJECTIVE Eating disorders (EDs) are a heterogenous group of disorders characterized by disturbed eating patterns. Links have been made between ED symptoms and control-seeking behaviors, which may cause relief from distress. However, whether direct behavioral measures of control-seeking behavior correlate with ED symptoms has not been directly tested. Additionally, existing paradigms may conflate control-seeking behavior with uncertainty-reducing behavior. METHOD A general population sample of 183 participants completed part in an online behavioral task, in which participants rolled a die in order to obtain/avoid a set of numbers. Prior to each roll, participants could choose to change arbitrary features of the task (such as the color of their die) or view additional information (such as the current trial number). Selecting these Control Options could cost participants points or not (Cost/No-Cost conditions). Each participant completed all four conditions, each with 15 trials, followed by a series of questionnaires, including the Eating Attitudes Test-26 (EAT-26), the Intolerance of Uncertainty Scale, and the Obsessive-Compulsive Inventory-Revised (OCI-R). RESULTS A Spearman's rank test indicated no significant correlation between total EAT-26 score and total number of Control Options selected, with only elevated scores on a measure of obsessions and compulsivity (OCI-R) correlating with the total number of Control Options selected (rs = .155, p = .036). DISCUSSION In our novel paradigm, we find no relationship between EAT-26 score and control-seeking. However, we do find some evidence that this behavior may be present in other disorders that often coincide with ED diagnosis, which may indicate that transdiagnostic factors such as compulsivity are important to control-seeking.

Abstract
BACKGROUND AND OBJECTIVES The role of anxiety as a risk factor for compulsive exercise elements among adolescents is unclear. Intolerance of uncertainty (IU), which is a risk feature for anxiety and eating disorders, may be an important, unexplored risk factor for compulsive exercise dimensions. This study aimed to examine the role of IU dimensions and anxiety on compulsive exercise elements. Given previous evidence indicating gender differences in compulsive exercise and IU levels, gender was included as a moderator. DESIGN/METHODS A total of 201 adolescent girls and 207 adolescent boys completed the following questionnaires: Eating Disorder Inventory-3, Intolerance of Uncertainty Scale-12 (IUS-12), a brief version of the State-Trait Anxiety Inventory and the Compulsive Exercise Test (CET). RESULTS The hierarchical regression analyses showed that the interaction between IUS-Prospective and gender emerged as a significant predictor of CET-Avoidance and CET-Weight control exercise beyond symptoms of eating disorders and anxiety. Post hoc analysis revealed that the IUS-Prospective was a significant predictor of CET-Avoidance and CET-Weight Control among boys, but not among girls. CONCLUSIONS These findings suggest that prospective IU may contribute towards obsessive-compulsive attitudes towards exercise among adolescent population, specifically among boys.

Abstract
AbstractThe Intolerance of Uncertainty Inventory (IUI) is a two-part inventory assessing the general unacceptability of uncertainty in terms of generalized maladaptive beliefs (IUI-A) and specific individuals’ reactions to uncertainty, such as avoidance, doubt, overestimation of threat, worry, control of uncertainty, and seeking reassurance (IUI-B). Previous research has examined the factor structure of both parts with mixed results, especially for IUI-A. The present study took advantage of the Farsi-language version to clarify the IUI factor structure, assess measurement invariance between clinical and nonclinical samples, and examine the criterion-related and incremental validity of IUI-A and IUI-B. We administered the IUI to a mixed psychiatric sample of patients who met DSM-IV criteria for affective disorders (N = 198) and community participants in relatively good health (N = 427). Exploratory structural equation modeling analyses were used to test alternative factor models and determine whether IUI factors predicted depression and anxiety symptoms. A bifactor model was found to be the best fit for IUI-A and IUI-B, and reliability analyses supported the use of the total scores for both parts. The IUI-A and IUI-B were scalar invariant. The general factors of each part and the IUI-B worry factor were higher in patients with affective disorders than in community participants. Validity analyses showed that the two general factors tapped into the same variance in depression and anxiety symptoms as the competing instruments, although not superior in predictive performance to the Intolerance of Uncertainty scale (IUS-12) and the Disorder Specific Intolerance of Uncertainty (DSIU) scale. The present study clarified the factorial structure of the IUI and provided evidence that IUI total scores are reliable and valid for assessing the Intolerance of Uncertainty construct and predicting clinical outcomes.

State of Mind Assessment in Relation to Adult Attachment and Text Analysis of Adult Attachment Interviews in a Sample of Patients with Anorexia Nervosa. Eur J Investig Health Psychol Educ 2022; 12:1760-1779.

Abstract
BACKGROUND Attachment theory represents one of the most important references for the study of the development of an individual throughout their life cycle and provides the clinician with a profound key for the purposes of understanding the suffering that underlies severe psychopathologies such as eating disorders. As such, we conducted a cross-sectional study with a mixed-methods analysis on a sample of 32 young women with anorexia nervosa (AN); this study was embedded in the utilized theoretical framework with the following aims: 1. to evaluate the state of mind (SoM) in relation to adult attachment, assuming a prevalence of the dismissing (DS) SoM and 2. to analyze the linguistic attachment profile emerging from the transcripts of the AAIs. METHODS Interviews were transcribed verbatim, coded, and analyzed using the linguistic inquiry and word count (LIWC) method. RESULTS The results were observed to be consistent with the referenced literature. The prevalence of a DS SoM (68.75%) is observed in the study sample, whereas the results of the lexical analysis of the stories deviate from expectations. Notably, the lexical results indicate the coexistence of the dismissing and entangled aspects at the representational level. CONCLUSIONS The study results suggest a high level of specificity in the emotional functioning of patients with AN, with a focusing on a pervasive control of emotions that is well illustrated by the avoidant/ambivalent (A/C) strategy described in Crittenden's dynamic-maturational model. These findings and considerations have important implications for clinical work and treatment, which we believe must be structured on the basis of starting from a reappraisal of emotional content.

Abstract
Previous studies suggest a stronger influence of visual signals on body image in individuals with eating disorders (EDs) than healthy controls; however, the influence of other exteroceptive sensory signals remains unclear. Here we used an illusion relying on auditory (exteroceptive) signals to manipulate body size/weight perceptions and investigated whether the mechanisms integrating sensory signals into body image are altered in subclinical and clinical EDs. Participants' footstep sounds were altered to seem produced by lighter or heavier bodies. Across two experiments, we tested healthy women assigned to three groups based on self-reported Symptomatology of EDs (SED), and women with Anorexia Nervosa (AN), and used self-report, body-visualization, and behavioural (gait) measures. As with visual bodily illusions, we predicted stronger influence of auditory signals, leading to an enhanced body-weight illusion, in people with High-SED and AN. Unexpectedly, High-SED and AN participants displayed a gait typical of heavier bodies and a widest/heaviest visualized body in the 'light' footsteps condition. In contrast, Low-SED participants showed these patterns in the 'heavy' footsteps condition. Self-reports did not show group differences. The results of this pilot study suggest disturbances in the sensory integration mechanisms, rather than purely visually-driven body distortions, in subclinical/clinical EDs, opening opportunities for the development of novel diagnostic/therapeutic tools.

Abstract
ObjectivesDisordered eating behaviors are prevalent among college-age individuals. Issues of control (e.g., perceptions of control; desire for control) are often salient for these individuals. Concerns regarding control can be exacerbated during transitions. The current study examined the extent to which disordered eating behaviors in college were predicted by locus of control, desire for control, and their interaction. We also explored whether these associations might be impacted by student life transitions (e.g., into/out of college). Participants and methods: A sample of 156 college students (72% women) was surveyed. Results: Both locus of and desire for control were predictive of disordered eating, but hypothesized moderations among locus of control, desire for control, and life transitions were primarily not supported. Conclusions: Issues surrounding perceptions of control are important for disordered eating treatments or prevention programs, while more research is needed on the role life transitions may play in exacerbating risk.

Abstract
BACKGROUND A key feature of anorexia nervosa is body image disturbances and is often expressed by dysfunctional body-related behaviours such as body checking and body avoiding. These behaviours are thought to contribute to both the maintenance and relapse of AN, yet empirical evidence is scarce. One variable that may contribute to the need for engaging in these behaviours is intolerance of uncertainty. This study aims to investigate body checking and body avoiding and its relations with intolerance of uncertainty in women with anorexia nervosa (AN-ill; 70), women recovered from AN (AN-rec; 85) and control group (127). METHODS Three questionnaires were completed, measuring eating pathology, intolerance of uncertainty and body checking and body avoiding. One-way ANOVAS were used to test group differences. Moderation analyses were used to investigate associations between variables. RESULTS Levels of intolerance of uncertainty, body checking and body avoiding were highest in AN-ill followed by AN-rec and, lastly, the control group, confirming group differences. Intolerance of uncertainty was associated with body checking in the AN-rec group and the control group but not in the AN-ill group. The association between intolerance of uncertainty and body avoiding was reported in the AN-rec group and only marginally in the control group. CONCLUSION Levels of intolerance of uncertainty, body checking and body avoiding were highest in AN-ill, however still elevated in AN-rec, confirming the presence of body image disturbances, even after recovery. The unique associations between intolerance of uncertainty and body checking and body avoiding within the studied groups may represent different stages of the illness. In the AN-rec group, the relation between intolerance of uncertainty, body checking and body avoiding may be driven by trait anxiety. For AN-ill group, body checking and body avoiding may eventually have grown into habitual patterns, rather than a strategy to ameliorate anxiety and uncertainty. Women with anorexia nervosa often experience disturbances in their body image and are expressed in body-related behaviours such as body checking and body avoiding. These behaviours are thought to contribute to both the maintenance and relapse of anorexia nervosa. Intolerance of uncertainty is defined as the incapacity to tolerate uncertainty and may contribute to the need for engaging in these behaviours. This study aims to investigate body checking and body avoiding and its relations with intolerance of uncertainty in women with anorexia nervosa (AN-ill; 70), women recovered from AN (AN-rec; 85) and control group (127). Three questionnaires were completed, measuring eating pathology, intolerance of uncertainty and body checking and body avoiding. Levels of intolerance of uncertainty, body checking and body avoiding were highest in AN-ill and still elevated in AN-rec, even after recovery. The associations between intolerance of uncertainty and body checking and body avoiding within the studied groups may represent different stages of the illness. In the AN-rec group, the relation between intolerance of uncertainty, body checking and body avoiding may be driven by trait anxiety. For AN-ill group, body checking and body avoiding may have grown into habitual patterns, rather than a strategy to ameliorate anxiety and uncertainty.

Broad and Narrow Transdiagnostic Risk Factors in Eating Disorders: A Preliminary Study on an Italian Clinical Sample. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19116886.

Abstract
Eating disorders are multifaceted psychopathologies and the transdiagnostic approach is currently considered a useful framework to understand their complexity. This preliminary study aimed to investigate both broad (i.e., intolerance of uncertainty and emotion dysregulation) and narrow (i.e., extreme body dissatisfaction) transdiagnostic risk factors underlying eating disorders. 50 Italian female patients seeking treatment for an eating disorder were involved (Mage = 31.6 years ± 12.8, 18–65). They completed self-report measures assessing emotion regulation difficulties, intolerance of uncertainty, extreme body dissatisfaction, general psychological distress, and eating disorder symptomatology. To explore whether the abovementioned transdiagnostic factors predicted patients’ psychological distress and eating disorder symptoms, two linear regressions were performed. Emotion dysregulation emerged as the only significant predictor of distress, while extreme body dissatisfaction was the only significant predictor of overall eating disorder symptomatology. Then, to analyze the differences between patients with anorexia nervosa and bulimia nervosa in intolerance of uncertainty and emotion regulation problems, t-tests were conducted. The two groups differed significantly in intolerance of uncertainty levels only, with higher scores obtained by patients with anorexia nervosa. Overall, our findings suggest that emotion dysregulation and extreme body dissatisfaction may be relevant constructs in eating disorders in general, while intolerance of uncertainty may be more involved in restrictive eating disorders. The clinical implications of such results are discussed.

Abstract
PURPOSE This study aimed to explore how parents of young people with a restrictive eating disorder (ED) experience and manage uncertainty. METHODS Seventeen parents of young people with a restrictive ED were recruited from multi-family therapy groups run within a specialised ED clinic. Five focus groups were conducted asking parents about their experience of uncertainty both prior and after the onset of their child's illness. RESULTS Data were analysed using interpretative phenomenological analysis which yielded seven superordinate themes.

Experiences of parents and patients hospitalised in a child psychiatric unit for anorexia nervosa after reorganisation of care imposed by the COVID-19 Pandemic in France: a qualitative study-The QUALICOVID study. J Eat Disord 2022; 10:57. [PMID: 35468851 PMCID: PMC9035507 DOI: 10.1186/s40337-022-00579-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 04/11/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Anorexia nervosa is a serious, albeit common mental illness that generally occurs during adolescence. Although outpatient care is recommended, hospitalisation is sometimes required. There is a dedicated hospitalisation unit caring for children and adolescents presenting with anorexia nervosa in Nancy, France. However, on 16 March 2020, a national lockdown was declared by the French government as the COVID-19 pandemic escalated in France. This resulted in the adjustment of hospital admissions accompanied by premature discharge and an intensive outpatient care programme. In the light of such changes, consideration should be given to the potential impact of changes in the care pattern for anorexic patients and their parents. The purpose of our study was to explore the experiences of anorexia nervosa patients hospitalised in the unit, and their parents, following changes in the care strategy. METHODS The study was conducted between weeks four and eight after lockdown was announced. The study cohort included all the patients treated for anorexia nervosa and hospitalised in the treatment unit before 16 March 2020 and their parents. A qualitative method was used and every subject was offered a semi-structured interview. Data were analysed by means of inductive thematic analysis. RESULTS Seven superordinate themes were identified: positive aspects, concerns, preparation, loss of landmarks and hospital security, gradual return to a "normal" life, relational aspects and the likelihood of disease progression. Moreover, all the parents and patients were satisfied with the intensive outpatient care offered on discharge. CONCLUSION Despite initial ambivalence, all patients and their parents viewed this unexpected hospital discharge positively in these exceptional conditions. This suggests that restructuring the care programme could prove beneficial with increasing use of outpatient management, thereby reducing the length of the hospital stay and adjusting the return to school. TRIAL REGISTRATION ID-RCB 2020-A01101-38-This project was approved by the Comité de Protection des Personnes (CPP) Sud Méditerranée IV [South Mediterranean IV Ethics Committee (EC)] on 5 May 2020.

Abstract
Anorexia Nervosa (AN) has the highest mortality rate of the mental disorders, with still less than 50% of affected individuals achieving recovery. Recent calls to bring innovative, empirical research strategies to the understanding of illness and its core psychopathological features highlight the need to address significant paucity of efficacious treatment. The current study brings a phenomenological approach to this challenge, synthesizing lived experience phenomena as described by qualitative literature. Fifty-three studies published between the years 1998 and 2021 comprising a total of 1557 participants aged 12-66 suffering from AN or sub-threshold AN are included. Reciprocal and refutational analysis generated six key third-order constructs: "emotion experienced as overwhelming," "identity," "AN as a tool," "internal conflict relating to Anorexia," "interpersonal communication difficulties" and "corporeality." Twenty-six sub-themes were identified, the most common being fear, avoidance, AN as guardian/protector, and AN as intertwined with identity. Some themes associated with current treatment models such as low self-esteem, need for social approval and feelings of fatness were less common. We highlight the significant role of intense and confusing emotion in AN, which is both rooted in and engenders amplified fear and anxiety. Restrictive eating functions to numb these feelings and withdraw an individual from a chaotic and threatening world whilst providing a sense of self around which to build an illness identity. Results have implications for therapeutic practice and overly protective weight and shape focused medical treatment models, which may serve to reinforce the disease.

Abstract
OBJECTIVES Difficulties in managing emotions have been implicated in the development and maintenance of anorexia nervosa (AN), and psychological treatment models seek to address this in putative targets of change. Yet the field of psychotherapy remains unclear and insufficiently evidenced about the process of change and how this is actually achieved, including in what steps and in what order within clinical treatment. This qualitative study sought to develop theory about the process of emotional change during recovery from anorexia. METHODS Semi-structured interviews were carried out with nine women currently engaged in psychological treatment for anorexia. Interviews included questions pertaining to participants' experience of anorexia, emotions, and emotion management. A constructivist version of grounded theory was employed. RESULTS The analysis produced 10 major categories, comprising over 60 focused codes. Categories were clustered together into three super categories, reflecting 3 distinct but interrelated phases of participants' journeys toward recovery. The phases were: (1) Coping in a world of uncertainty, (2) Seeing through the façade of anorexia, and (3) Recovery and growth. Whilst movement toward later positions often appeared to be contingent on earlier ones, the analysis suggests that this was not an entirely linear process and that participants moved between positions as they grappled with the process of change. Participants came to view behaviors associated with anorexia as emotion-management strategies that were not working and as a façade. As they moved toward recovery and growth, they became less confined by their need for safety, and to see emotions as meaningful and valuable. Becoming more connected to emotional experience and expression, coincided with positive shifts in their intra and interpersonal relationships. CONCLUSION These findings support the recent shift toward emotion-focused models of anorexia. They also highlight an important focus in supporting individuals with AN to connect with, and be guided by, emotional experiences in their relationships with themselves and the world around them. This new grounded theory offers a putative process of change that could be utilized to guide intervention development.

Abstract
BACKGROUND Inherent to anorexia nervosa are repetitive thoughts about weight and shape. Growing research suggests the relevance of intolerance of uncertainty and worry in maintaining these types of repetitive thoughts. The relation between these cognitive processes and weight and shape concerns in adolescent girls with anorexia nervosa is understudied. This study investigated associations between prospective (desire for predictability) and inhibitory (uncertainty paralysis) intolerance of uncertainty, and weight and shape concerns and the mediating role of worry in these associations. METHODS In a cross-sectional study, 93 adolescent girls with anorexia nervosa completed questionnaires measuring the variables of interest. A mediation model with worry as a mediator between inhibitory and prospective intolerance of uncertainty and weight and shape concerns was tested. RESULTS A total and direct effect of inhibitory intolerance of uncertainty on weight and shape concerns was found. Worry did not mediate this relation. CONCLUSIONS These results confirm the importance of inhibitory intolerance of uncertainty in adolescent girls with anorexia nervosa, more specifically to weight and shape concerns. This group may benefit from intervention strategies targeting intolerance of uncertainty. General worry seems less relevant to weight and shape concerns in adolescent girls with anorexia nervosa. Adolescent girls with anorexia nervosa often experience repetitive thoughts about weight and shape. Growing research suggests the relevance of intolerance of uncertainty and worry in maintaining these types of repetitive thoughts. Intolerance of uncertainty is defined as the incapacity to tolerate uncertainty and is often divided into two components; prospective intolerance of uncertainty (desire for predictability) and inhibitory intolerance of uncertainty (uncertainty paralysis). The relation between intolerance of uncertainty, worry and weight and shape concerns in adolescent girls with anorexia nervosa is understudied. This study aims to investigate study relations between prospective and inhibitory intolerance of uncertainty, worry, and weight and shape concerns. A total of 93 adolescent girls with anorexia nervosa completed three questionnaires, measuring prospective and inhibitory intolerance of uncertainty worry, and weight and shape concerns, respectively. The results of this study confirmed the importance of inhibitory intolerance of uncertainty in adolescent girls with anorexia nervosa, more specifically to weight and shape concerns. This group may benefit from intervention strategies targeting intolerance of uncertainty. General worry seems less relevant to weight and shape concerns in adolescent girls.

Abstract
BACKGROUND Cognitive disturbances such as impairments in learning are thought to play a role in adult Anorexia Nervosa (AN). It is remains unclear to what extent these disturbances result from starvation of the brain, or relate to an abnormal premorbid cognitive profile. This study investigates learning processes in adolescents with AN, hypothesizing that implicit learning is intact, as found previously in explicit learning tasks. Secondly, we hypothesized that anxiety and depression symptoms, inherent to AN, are associated to learning processes in AN. METHODS In total 46 adolescents diagnosed with AN and 44 control participants were administered an implicit category learning task in which they were asked to categorize simple perceptual stimuli (Gabor patches) based on a linear integration (i.e., an implicit task) of orientation and spatial frequency of the stimulus. A subgroup of adolescents (n = 38) also completed a task assessing explicit learning. RESULTS Model-based analyses indicated that adolescents with AN performed significantly more accurately compared to their healthy peers regardless of whether they used the optimal strategy or not. Depression and anxiety did not relate to learning performance in the AN group. CONCLUSIONS Overall, our findings of augmented implicit and explicit learning in adolescents with AN corroborate recent studies that suggested higher stimulus-response learning during prediction error paradigms. Learning disturbances in adult AN may then be at least partly due to long-term malnourishment, highlighting the importance of early recognition and refeeding in treatments for AN.

Abstract
There is a critical need to identify processes that may influence outcome in existing treatments for eating disorders (EDs). Intolerance of uncertainty (IU), which refers to excessive distress regarding uncertain situations, is a well-established feature of anxiety disorders. Emerging work suggests that IU decreases over the course of cognitive-behavioral treatments and may relate to better treatment outcomes. As some literature has suggested IU may functionally maintain ED symptoms, testing whether changes in IU over treatment relate to outcome may result in the identification of novel treatment targets. This study aimed to build upon past work documenting links between IU and ED symptoms by exploring changes in IU over treatment and links between early change in IU (1-month) and discharge symptoms. Participants (N = 274) receiving partial hospitalization treatment completed the Eating Pathology Symptoms Inventory and Intolerance of Uncertainty Scale at admission, 1-month post-admission, and discharge. Results suggested that IU significantly reduced from admission to discharge and that reductions in IU scores from admission to 1-month related to cognitive restraint, dietary restriction, and body image at discharge. However, this pattern did not hold for exercise, binge eating, or purging. Altogether, these results replicate past work supporting IU as a common feature across ED diagnoses and provide initial data suggesting that targeting IU early in treatment may enhance treatment outcomes.

Abstract
Severe and Enduring Anorexia Nervosa (SE-AN) is a chronic eating disorder characterized by long-term starvation and its physical and psychological sequelae, and severe loss of quality of life. Interactions between neurobiological changes caused by starvation, vulnerability (personality) traits, and eating behaviors play a role. Several other factors, such as increased fear and decreased social cognition, have also been found in relation to SE-AN. With this in mind, we aim to add to the understanding of SE-AN by introducing the concept of mental capacity (MC), which refers to the ability to understand and process information-both on a cognitive and an emotional level-and then make a well-informed choice. MC may be an important construct within the context of SE-AN. Furthermore, we will argue how impaired decision-making processes may underlie, fuel, or contribute to limited MC in SE-AN. We will speculate on the importance of dysfunctional emotion processing and anxiety-related processes (e.g., a high intolerance of uncertainty) and their potential interaction with decision-making. Lastly, we will propose how these aspects, which to our knowledge have previously received little attention, may advise research and treatment or help in dealing with the "want but cannot" situation of life-threatening AN.

Abstract
Eating disorders are widespread illnesses with significant global impact. There is growing concern about how young people overuse online resources leading to mental health sequelae. We gathered data from 639 individuals from a population cohort. Participants were all young adults at the point of contact and were grouped as having probable eating disorder with excessive exercise (n = 37) or controls (n = 602). We measured obsessionality, compulsivity, impulsivity, and problematic internet use. Group differences in these domains were evaluated; and structural equation modelling (SEM) was used to assess structural relationships between variables. Cases had higher scores of obsessional thoughts of threat (Cohen's d = 0.94, p < 0.001), intolerance towards uncertainty (Cohen's d = 0.72; p < 0.001), thoughts of importance and control (Cohen's d = 0.65, p < 0.01), compulsivity (Cohen's d = 0.72; p < 0.001), negative urgency (Cohen's d = 0.75, p < 0.001), and higher problematic usage of the internet (Cohen's d = 0.73; p-corrected <0.001). Our SEM showed significant partial mediation of problematic internet use on both the effect of obsessionality latent factor on cases (z-value = 2.52, p < 0.05), as well as of sensation seeking latent factor on cases (z-value = 2.09, p < 0.05). Youth with eating disorder and heightened exercise levels have increased obsessive thoughts of threat, compulsivity traits and sensation seeking impulsivity. The association between obsessive thoughts and eating disorders, as well as sensation seeking and eating disorders were partially mediated by problematic internet use. Problematic internet use may be playing a role in the development or maintenance of eating disorder symptoms in the background of obsessional thoughts and sensation seeking impulsive traits.

Abstract
INTRODUCTION Inefficient problem solving in the social domain may be one of the difficulties underlying the interpersonal challenges thought to maintain anorexia nervosa (AN). However, past studies have neglected to control for depression, anxiety, and intolerance of uncertainty (IU), which are known to contribute to social problem solving. METHODS This study aimed to investigate whether adults with AN would show differences in social problem solving on an experimental task (Means-End Problem Solving; MEPS) and report differences in their attitudes (positive, negative) toward social problem solving and their use of social problem-solving styles (rational, impulsive-careless, avoidant) on the Social Problem-Solving Inventory Revised (SPSRI) compared to a non-AN control group. RESULTS Seventy-four adult women took part (30 with AN and 44 non-AN controls), and data show that those with AN generated significantly less effective solutions on the MEPS (d = 1.96) reported overall poorer social problem solving on the SPSRI (d = 0.58), reporting more negative and less positive attitudes toward social problem solving, and less impulsive and more avoidant social problem-solving styles. However, those with AN did not differ from controls in being able to rationalize social problems. Once depression (Beck Depression Inventory: BDI), state anxiety (State-Trait Anxiety Inventory: STAI), and IU (Intolerance of Uncertainty Scale-12; IUS-12) were included as covariates, these differences were no longer significant, suggesting that comorbid depression, anxiety, and IU symptoms may contribute to social problem solving in AN. CONCLUSIONS There was no specific effect of depression. Treating anxiety and IU might help to improve social problem solving and enable people with AN to be able to better access social support to aid their recovery.

BACKGROUND Intolerance of uncertainty-the tendency to overestimate the chance of and be unwilling to accept potential, but unlikely, negative outcomes in uncertain situations-is a cognitive construct that has been shown to affect symptoms and limitations for patients with traumatic and nontraumatic upper-extremity conditions. Cognitive flexibility and tolerance of uncertainty can be trained and practiced, with the potential to increase musculoskeletal health. However, to our knowledge, the degree to which intolerance of uncertainty might be associated with symptom intensity and the magnitude of limitations in adults with upper-extremity problems has not been characterized. QUESTIONS/PURPOSES After accounting for personal and social factors, is intolerance of uncertainty independently associated with (1) the magnitude of physical limitations and (2) pain intensity? METHODS In this cross-sectional, observational study, 139 new and returning patients presenting to one of four orthopaedic offices in a large urban area completed the Intolerance of Uncertainty Scale (a validated measure of the level of comfort with uncertain situations), the Patient-reported Outcomes Measurement Information System-Physical Function Upper Extremity computer adaptive test (to measure the magnitude of limitations), and an 11-point ordinal measure of pain intensity. The mean age of the 139 participants was 51 years ± 16 years and 55% (76 of 139) were men. Participants presented to the clinics with a wide variety of upper-extremity conditions, such as trigger finger, distal radius fractures, lateral epicondylitis, or non-specific shoulder pain. We also assessed sex, race, marital status, education level, income, public versus private insurance, area deprivation index, and the participant's self-perception of their healthcare experience through a multiple-choice question (answer choices: none, some, a little, and a lot of experience). The following patient characteristics were more common in our study participants: white, employed, part of a married or unmarried couple, and private insurance coverage. We created two multivariable linear regression models to assess factors independently associated with the magnitude of limitations and pain intensity. RESULTS After controlling for potentially confounding variables including sex, insurance, area deprivation index, and type of visit, we found that fewer physical limitations were associated with a greater intolerance of uncertainty (regression coefficient [β] -0.30; 95% confidence interval, -0.50 to -0.10; p = 0.003; semi-partial r = 0.07; adjusted r for the full model = 0.16), as was being a man (β 3.2; 95% CI, 0.08-6.3; p = 0.045; semi-partial r = 0.03) and having private insurance coverage (β 5.2; 95% CI, 2.1-8.2; p = 0.001; semi-partial r = 0.08). After controlling for one important potentially confounding variable, the level of education, greater pain intensity was associated with a greater intolerance of uncertainty (β 0.08; 95% CI, 0.02-0.14; p = 0.009; semi-partial r = 0.05; adjusted r for the full model = 0.08). CONCLUSIONS Intolerance of uncertainty-a byproduct of cognitive bias and error, which are elements of the normal functioning of the human mind-increases limitations and pain intensity across diagnoses, independent of demographic and social factors. Future studies can address the effect of strategies that incorporate mindset training (for example, cognitive behavioral therapy and its derivatives) on musculoskeletal symptoms and limitations.

Intolerance of uncertainty moderates the relationship between high personal standards but not evaluative concerns perfectionism and eating disorder symptoms cross-sectionally and prospectively. Eat Behav 2019; 35:101340. [PMID: 31731235 DOI: 10.1016/j.eatbeh.2019.101340] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 10/23/2019] [Accepted: 10/23/2019] [Indexed: 11/18/2022]
Abstract
Two dimensions of perfectionism related to eating disorder (ED) symptoms are evaluative concerns and high standards. Evaluative concerns are consistently linked with ED symptoms, whereas there are conflicting results regarding high standards and ED symptoms. High standards are unrelated to ED symptoms in some studies and are linked to higher ED symptoms in others. Intolerance of uncertainty (IU) may influence the relation between high standards and ED symptoms; individuals elevated in both IU and high standards may find it distressing to be uncertain about future situations for fear of not living up to high expectations and use ED behaviors to cope with such uncertainty. In the current study (N = 216), we explored whether IU moderates the relationships between high standards and evaluative concerns and ED symptoms, both cross-sectionally and prospectively across two weeks. IU significantly moderated high standards and ED symptoms both cross-sectionally and across time while accounting for baseline ED symptoms, but did not moderate the relationship between evaluative concerns and ED symptoms. Higher standards were associated with greater ED symptoms in individuals higher, but not lower in IU. These findings suggest high standards may only contribute to ED symptoms when individuals are also high in IU.

Intolerance of uncertainty and eating disorder behaviour: Piloting a consumption task in a non-clinical sample. J Behav Ther Exp Psychiatry 2019; 65:101492.

Abstract
BACKGROUND AND OBJECTIVES Intolerance of uncertainty (IU) is a transdiagnostic process contributing to the maintenance of anxiety disorders, and is a potential target for treatment. Recent literature has investigated IU as a cognitive process underpinning pathological fear and anxiety in Anorexia Nervosa (AN). The current study was designed to examine trait and state IU, and their relationship to restrictive eating disorder symptoms, anxiety, worry, cognitive rigidity and eating behaviour. METHODS A sample of undergraduate women (N = 85) completed measures of eating disorder symptoms, IU, cognitive rigidity and worry. Participants were randomised to complete an eating task under one of two conditions: the "certain" condition received a high-calorie meal and nutritional information, while the "uncertain" condition received the meal alone. During the meal, state IU and state anxiety were examined at three time-points (baseline, pre-eating, post-eating). RESULTS Trait IU was correlated with cognitive rigidity, worry, global eating disorder symptoms, and, in particular, dietary restraint. No differences emerged between conditions with respect to eating-related anxiety, or amount of food eaten. Controlling for condition and eating disorder symptoms, state IU predicted pre-eating anxiety. Beyond the contribution of condition, BMI and eating disorder symptoms, state IU predicted consumption, specifically greater dietary restriction. LIMITATIONS The study employed a non-clinical sample. CONCLUSIONS IU may be implicated in a rigid cognitive style, the anxiety response to energy-dense food, and restrictive eating behaviour. Should these findings be replicated in a clinical sample, then IU might emerge as an adjunctive treatment target for AN.

Abstract
Impaired decision-making under conditions of uncertainty seems to contribute to the expression and maintenance of anorexia nervosa (AN), but it is not clear whether this impairment is a disease state that would remit with treatment, or a persisting trait in patients with AN. To examine this question, a longitudinal study was conducted in 12 female inpatients with AN (age M = 22.2, SE = 1.36), before (Time-1) and after reaching a body mass index of >17.5 kg/m2 (Time-2). Intolerance of uncertainty (IU) was assessed via a decision-making task, the wheel of fortune (WOF). Weight gain at Time-2 was accompanied with significant changes in uncertainty-related performance compared to Time-1 [(Time × Uncertainty), p < 0.05]. At Time-1, reaction times (RTs) varied in function of uncertainty, while at Time-2, uncertainty did not modulate RTs. These findings support a change in decision-making under uncertainty with successful weight-rehabilitation in AN. While IU was present in underweight patients, it became non-significant after weight restoration.

Abstract
PURPOSE Research is consistently reporting elevated levels of intolerance of uncertainty (IU) in individuals with an eating disorder (ED). Less is known about the phenomenology of uncertainty for this clinical group. The present study aims to advance our understanding of the relationship between IU and restrictive EDs by providing insight into young people's subjective experiences of uncertainty. METHODS Thirteen young people with a restrictive ED were recruited from multi-family therapy groups run within the Maudsley Centre for Child and Adolescent Eating Disorders at the South London and Maudsley NHS Foundation Trust. Three focus groups were conducted asking young people to discuss their views, experiences and coping strategies when faced with uncertainty. RESULTS Data were analysed using interpretative phenomenological analysis which yielded five superordinate themes: (1) young people perceived uncertainty as something negative; (2) high levels of anxiety and stress were identified as primary responses to uncertainty; (3) ED behaviours were given a functional role in reducing uncertainty; (4) need to control various aspects of young peoples' lives was of high importance; (5) young people discussed how they struggled to find ways to cope with uncertainty and often used behaviours associated with the eating disorder psychopathology as coping strategies. CONCLUSION Young people's experiences of what uncertainty is like for them revealed a dynamic interplay between ED symptoms and fear of uncertainty. Findings support IU as a relevant concept for young people suffering from a restrictive ED and indicate that further exploration of IU from both theoretical and clinical perspectives could be fruitful.

Abstract
In this paper, we argue that Anorexia Nervosa (AN) can be explained as arising from a 'lost sense of emotional self.' We begin by briefly reviewing evidence accumulated to date supporting the consensus that a complex range of genetic, biological, psychological, and socio-environmental risk and maintenance factors contribute to the development and maintenance of AN. We consider how current interventions seek to tackle these factors in psychotherapy and potential limitations. We then propose our theory that many risk and maintenance factors may be unified by an underpinning explanation of emotional processing difficulties leading to a lost sense of 'emotional self.' Further, we discuss how, once established, AN becomes 'self-perpetuating' and the 'lost sense of emotional self' relentlessly deepens. We outline these arguments in detail, drawing on empirical and neuroscientific data, before discussing the implications of this model for understanding AN and informing clinical intervention. We argue that experiential models of therapy (e.g., emotion-focused therapy; schema therapy) be employed to achieve emergence and integration of an 'emotional self' which can be flexibly and adaptively used to direct an individual's needs and relationships. Furthermore, we assert that this should be a primary goal of therapy for adults with established AN.

Food vs money? Effects of hunger on mood and behavioral reactivity to reward in anorexia nervosa. Appetite 2018; 134:26-33.

Abstract
BACKGROUND Previous studies using neuroimaging and behavioral measures reported altered reward processing in anorexia nervosa (AN). In addition, anhedonia states are frequently reported in AN, potentially due to the physiological stress produced by the permanent starvation. We investigated the effect of fasting and satiety on mood and reaction times to monetary rewards in AN patients and healthy controls. METHODS Twenty-four participants with acute AN (BMI 14.4 (11.9-15.5) Kg/m2) and 17 age and gender matched healthy, normal weight subjects (HW) (BMI 21.8 (18.9-24.9) Kg/m2) performed a reward task (the wheel of fortune) involving uncertain (50/50 probability of winning high and low rewards), safe and risky (30/70 and 10/90 probabilities) categories in fasted (after an 8-h fasting period) and fed (after intake of a standardized meal) states. Data analysis was done with linear mixed models. RESULTS AN reacted slower than HW when maximum uncertainty (50/50) was involved. Positive mood in response to winning was higher when fasting especially for HW, while negative mood in response to not winning was higher in the fed state for both groups. Still, HW were more reactive than AN to not winning a highly predictable monetary reward (10/90 safe). CONCLUSION The data on the reaction times indicate an impaired motor response to uncertainty in AN. Mood reactivity to winning a monetary reward does not seem to be impaired in AN, however, our results suggest that negative mood in response to not winning is less adaptive in AN. Implications to clinical psychotherapy are discussed.

Abstract
Intolerance of Uncertainty is a fundamental transdiagnostic personality construct hierarchically organized with a core general factor underlying diverse clinical manifestations. The current study evaluated the construct validity of the Intolerance of Uncertainty Inventory, a two-part scale separately assessing a unitary Intolerance of Uncertainty disposition to consider uncertainties to be unacceptable and threatening (Part A) and the consequences of such disposition, regarding experiential avoidance, chronic doubt, overestimation of threat, worrying, control of uncertain situations, and seeking reassurance (Part B). Community members (N = 1046; Mean age = 36.69 ± 12.31 years; 61% females) completed the Intolerance of Uncertainty Inventory with the Beck Depression Inventory-II and the State-Trait Anxiety Inventory. Part A demonstrated a robust unidimensional structure and an excellent convergent validity with Part B. A bifactor model was the best fitting model for Part B. Based on these results, we compared the hierarchical factor scores with summated ratings clinical proxy groups reporting anxiety and depression symptoms. Summated rating scores were associated with both depression and anxiety and proportionally increased with the co-occurrence of depressive and anxious symptoms. By contrast, hierarchical scores were useful to detect which facets mostly separated between for depression and anxiety groups. In sum, Part A was a reliable and valid transdiagnostic measure of Intolerance of Uncertainty. The Part B was arguably more useful for assessing clinical manifestations of Intolerance of Uncertainty for specific disorders, provided that hierarchical scores are used. Overall, our study suggest that clinical assessments might need to shift toward hierarchical factor scores.

Abstract
BACKGROUND Despite reporting low levels of well-being, anorexia nervosa patients express temperament traits (e.g., extraversion and persistence) necessary for high levels of life satisfaction. Nevertheless, among individuals without eating disorders, a balanced organization of the flow of time, influences life satisfaction beyond temperamental dispositions. A balanced time perspective is defined as: high past positive, low past negative, high present hedonistic, low present fatalistic, and high future. We investigated differences in time perspective dimensions, personality traits, and life satisfaction between anorexia nervosa patients and matched controls. We also investigated if the personality traits and the outlook on time associated to positive levels of life satisfaction among controls also predicted anorexia patients' life satisfaction. Additionally, we investigated if time perspective dimensions predicted life satisfaction beyond personality traits among both patients and controls. METHOD A total of 88 anorexia nervosa patients from a clinic in the West of Sweden and 111 gender-age matched controls from a university in the West of Sweden participated in the Study. All participants responded to the Zimbardo Time Perspective Inventory, the Ten Item Personality Inventory, and the Temporal Satisfaction with Life Scale. RESULTS A t-test showed that patients scored higher in the past negative, the present fatalistic, and the future dimensions, lower in the past positive and the present hedonistic dimensions, higher in conscientiousness, extraversion, and agreeableness, and lower in life satisfaction. Regression analyses showed that life satisfaction was predicted by openness to experience and emotional stability for controls and by emotional stability among patients. When time dimensions were entered in the regression, emotional stability and the past negative and past positive time dimensions predicted life satisfaction among controls, but only the past positive and present hedonistic time dimensions predicted life satisfaction among patients. CONCLUSION Anorexia patients were less satisfied with life despite being more conscientious, social, and agreeable than controls. Moreover, compared to controls, patients had an unbalanced time perspective: a dark view of the past (i.e., high past negative), a restrained present (i.e., low present hedonistic) and an apocalyptic view of the future (i.e., high present fatalistic). It is plausible to suggest that, therapeutic interventions should focus on empowering patients to cultivate a sentimental and positive view of the past (i.e., high past positive) and the desire to experience pleasure without concern for future consequences (i.e., high present hedonistic) so that they can make self-directed and flexible choices for their own well-being. Such interventions might have effects on life satisfaction beyond the patients' temperamental disposition.

Abstract
Altered inhibitory control has been implicated in the development and maintenance of eating disorders (ED), however it is unclear how different types of inhibitory control are affected across the EDs. We explored whether individuals with bulimia nervosa (BN), binge eating disorder (BED) and anorexia nervosa (AN) differed from healthy individuals (HC) on two types of motor inhibitory control: proactive inhibition (related to the preparation/initiation of a response) and reactive inhibition (withholding a response in reaction to a signal). Ninety-four women (28 AN, 27 BN, 11 BED, 28 HC) completed two neuropsychological tasks (a cued reaction time task and a stop signal task), and questionnaires assessing clinical variables, mood, anxiety, and inhibitory control. Self-reported inhibitory control was poorer in women with BN compared to the HC and AN groups, but greater in women with AN compared to all other groups. However, no group differences in reactive inhibition were observed. Proactive inhibition was augmented in women with AN compared to HC, and this was related to self-reported intolerance of uncertainty. The findings suggest that proactive inhibition may be a relevant target for behavioural interventions for AN, and call for further research into the relationship between intolerance of uncertainty and proactive inhibition.

Abstract
BACKGROUND Intolerance of Uncertainty (IU) is recognized for its contribution to various psychopathologies, in particular anxiety and depression. Studies highlight the relevance of IU for Eating Disorders (EDs) however, potential factors contributing to IU in EDs remain unstudied. METHODS Three hundred and forty-nine women with ED symptoms and 214 individuals without ED symptoms were recruited and compared on levels of IU, insecure (anxious and avoidant) attachment styles, extraversion and openness. Secondly, the contribution of these factors to IU were tested. RESULTS Compared to the non-ED group, the ED group scored higher on IU, insecure attachment, and lower on extraversion and openness. Regression analyses confirmed that higher insecure attachment, and lower extraversion predicted higher IU scores in the ED group, and that insecure attachment predicted higher IU scores in the non-ED group. CONCLUSIONS Results confirm the relevance of IU to ED, and demonstrate that personality traits and insecure attachment styles contribute to IU in ED. Findings add to the growing literature on IU in ED and suggest that people with EDs may benefit from clinical interventions targeting IU.

WP1b used a randomised controlled trial (RCT) [International Standard Randomised Controlled Trial Number (ISRCTN) 42594993] to evaluate a prevention programme for EDs in schools. WP2a evaluated an inpatient treatment for AN using case reports, interviews and a quasi-experimental trial. WP2b used a RCT (ISRCTN67720902) to evaluate two outpatient psychological therapies for AN. WP3 used a RCT (ISRCTN06149665) to evaluate an intervention for carers of inpatients with AN. WP4 used actimetry, self-report and endocrine assessment to examine physical activity (PA) in AN. WP5 conducted a RCT (ISRCTN18274621) of an e-mail-guided relapse prevention programme for inpatients with AN. WP6 analysed cohort data to examine the effects of maternal EDs on fertility and their children’s diet and growth. WP7a examined clinical case notes to explore how access to specialist ED services affects care pathways and user experiences. Finally, WP7b used data from this programme and the British Cohort Study (1970) to identify the costs of services used by people with AN and to estimate annual costs of AN for England.ResultsWP1a: a brief training programme improved knowledge, attitudes and confidence of school staff in managing EDs in school. WP1b: a teacher-delivered intervention was feasible and improved risk factors for EDs in adolescent girls. WP2a: both psychological therapies improved outcomes in outpatients with AN similarly, but patients preferred one of the treatments. WP2b: the inpatient treatment (Cognitive Remediation and Emotional Skills Training) was acceptable with perceived benefits by patients, but showed no benefits compared with treatment as usual (TAU). WP3: compared with TAU, the carer intervention improved a range of patient and carer outcomes, including carer burden and patient ED symptomatology. WP4: drive to exercise is tied to ED pathology and a desire to improve mood in AN patients. PA was not increased in these patients. WP5: compared with TAU, the e-mail-guided relapse prevention programme resulted in higher body mass index and lower distress in patients at 12 months after discharge. WP6: women with an ED had impaired fertility and their children had altered dietary and growth patterns compared with the children of women without an ED. WP7a: direct access to specialist ED services was associated with higher referral rates, lower admission rates, greater consistency of care and user satisfaction. WP7b: the annual costs of AN in England are estimated at between £45M and £230M for 2011.ConclusionsThis programme has produced evidence to inform future intervention development and has developed interventions that can be disseminated to improve outcomes for individuals with AN. Directions for future research include RCTs with longer-term outcomes and sufficient power to examine mediators and moderators of change.Trial registrationCurrent Controlled Trials ISRCTN42594993, ISRCTN67720902, ISRCTN06149665 and ISRCTN18274621.FundingThis project was funded by the National Institute for Health Research (NIHR) Programme Grants for Applied Research programme and will be published in full inProgramme Grants for Applied Research; Vol. 5, No. 16.

Abstract
Pathological fear and anxiety regarding food, eating, weight and body shape are at the core of eating disorder (ED) psychopathology. To manage anxiety, patients develop complicated repertoires of ritualistic and repetitive behaviours, which can lead to total functional impairment. Yet the cognitive processes underlying anxiety, fear, and anxiety-driven behaviours in EDs remain poorly understood. Intolerance of Uncertainty (IU) is defined as a tendency to react negatively on an emotional, cognitive, and behavioural level to uncertain situations and events. There is substantial evidence that IU is a transdiagnostic process that contributes to the maintenance of anxiety disorders; however, IU may also be relevant to the understanding and treatment of EDs. The current review summarises the growing literature examining IU in relation to ED symptoms, including restriction, bingeing, purging, ritualised behaviours, reassurance-seeking and body checking. Extending from the obsessive-compulsive disorder (OCD) and anxiety disorder literature, we propose that IU provides a novel theoretical and clinical framework from which to understand the anxiety, fixation with rules and rituals, and the cognitively rigid profile that is characteristic of ED presentations. We conclude with suggestions for future research, and discuss IU as a potential treatment target for core features of EDs and comorbid symptoms.

Abstract
Intolerance of uncertainty (IU) is proposed to be a transdiagnostic vulnerability factor for various emotional disorders. There is robust evidence for the role of IU in anxiety and depressive disorders, but a paucity of evidence in eating disorders (ED). This study evaluated the factorial validity, internal consistency, and convergent validity of the Intolerance of Uncertainty Scale-Short Form (IUS-12; Carleton, Norton, & Asmundson, 2007), and examined whether IU is associated with ED pathology and comorbid emotional symptoms, in a clinical sample with EDs (N=134). A unitary factor solution provided the best fit. The IUS-12 showed excellent internal consistency, and good convergent validity. IU had an indirect effect on dietary restraint, purging, and emotional symptoms via overvaluation of eating, weight, and shape. The indirect effect was not significant for bingeing. Findings provide partial support for the notion that IU is a vulnerability factor for ED pathology and support the notion that IU is a transdiagnostic vulnerability factor for emotional symptoms. Limitations, research implications, and future directions for research are discussed.

Abstract
Intolerance of uncertainty (IU) is a transdiagnostic construct associated with several anxiety and related disorders. Three studies were conducted to explore the potential relationship between IU and body dysmorphic disorder (BDD). Study 1 revealed a positive relationship between IU and BDD symptoms above symptoms of anxiety and depression in an unselected student sample (N=88). Study 2 demonstrated a similar relationship between IU and BDD symptoms above negative affectivity and intolerance of ambiguity in a community sample (N=116). Study 3 found that a clinical BDD sample (N=23) reported greater IU than healthy controls (N=20), though this relationship was accounted for by symptoms of anxiety and depression. Greater IU predicted functional impairment in the clinical sample above BDD symptoms and past-week anxiety and depression. The observed relationship between IU and BDD symptoms provides preliminary support for the relevance of IU to this population.

Abstract
Patients with anorexia nervosa (AN) display impaired social interactions, implicated in the development and prognosis of the disorder. Importantly, social behavior is modulated by reward-based processes, and dysfunctional at-brain-level reward responses have been involved in AN neurobiological models. However, no prior evidence exists of whether these neural alterations would be equally present in social contexts. In this study, we conducted a cross-sectional social-judgment functional magnetic resonance imaging (fMRI) study of 20 restrictive-subtype AN patients and 20 matched healthy controls. Brain activity during acceptance and rejection was investigated and correlated with severity measures (Eating Disorder Inventory -EDI-2) and with personality traits of interest known to modulate social behavior (The Sensitivity to Punishment and Sensitivity to Reward Questionnaire). Patients showed hypoactivation of the dorsomedial prefrontal cortex (DMPFC) during social acceptance and hyperactivation of visual areas during social rejection. Ventral striatum activation during rejection was positively correlated in patients with clinical severity scores. During acceptance, activation of the frontal opercula-anterior insula and dorsomedial/dorsolateral prefrontal cortices was differentially associated with reward sensitivity between groups. These results suggest an abnormal motivational drive for social stimuli, and involve overlapping social cognition and reward systems leading to a disruption of adaptive responses in the processing of social reward. The specific association of reward-related regions with clinical and psychometric measures suggests the putative involvement of reward structures in the maintenance of pathological behaviors in AN.

Abstract
BACKGROUND Alexithymia and intolerance of uncertainty (IU) are relevant factors in social and emotional processing abilities in anorexia nervosa (AN) eventually rendering emotional coping difficult. However, the link potentially existing in AN between IU and alexithymia has been so far understudied. SAMPLING AND METHODS Sixty-one patients affected by AN and 59 healthy controls (HC) were enrolled and assessed for study purposes. All participants completed the following self-report questionnaires: Intolerance of Uncertainty Scale, State Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI) and Toronto Alexithymia Scale. RESULTS IU and alexithymia were greater in patients with AN when compared to HC. Moreover, in both AN and HC groups, IU and alexithymia significantly correlated with each other as well as with anxiety (STAI score) and depression (BDI score). No correlations were found between alexithymia and age. Patients' duration of illness was negatively correlated with two alexithymia subscales. After adjusting for anxiety, depression, body mass index and duration of illness (for AN), the correlation between IU and alexithymia remained significant. CONCLUSIONS In addition to confirming previous findings on marked levels of IU and alexithymia in AN, this study showed for the first time a correlation between IU and alexithymia in both AN and HC. Moreover, this result remained significant after controlling for a number of clinical variables. Taken together, these findings may have useful clinical implications for the treatment of AN sufferers. © 2015 S. Karger AG, Basel.

Abstract
This study reviews research on the construct of intolerance of uncertainty (IU). A recent factor analysis (Journal of Anxiety Disorders, 25, 2012, p. 533) has been used to extend the transdiagnostic model articulated by Mansell (2005, p. 141) to focus on the role of IU as a facet of the model that is important to address in treatment. Research suggests that individual differences in IU may compromise resilience and that individuals high in IU are susceptible to increased negative affect. The model extension provides a guide for the treatment of clients presenting with uncertainty in the context of either a single disorder or several comorbid disorders. By applying the extension, the clinician is assisted to explore two facets of IU, "Need for Predictability" and "Uncertainty Arousal."

Abstract
This qualitative study aimed to explore experiences of women currently undergoing specialist inpatient treatment for anorexia nervosa. Interviews were carried out with 21 women with a diagnosis of anorexia nervosa from a specialist adult inpatient eating disorder unit. Five master themes emerged using thematic analysis: (1) shifts in control, (2) experience of transition, (3) importance of supportive staff relationships, (4) sharing with peers and (5) process of recovery and self-discovery. Findings suggest that patients experience a process of change and adjustment in relation to levels of perceived personal control, attachment to the treatment environment and a sense of self-identity.

Abstract
Anorexia nervosa (AN) is a severe mental disorder that affects mainly young females. In adults with a well-established form of the illness, it is hard to treat. In 2006, we proposed a maintenance model of AN, combining intra- and interpersonal factors and we have recently refined this model. The model encompasses four main maintaining factors (a thinking style characterized by rigidity, detail focus, and a fear of making mistakes; an avoidant emotion processing and relational style; positive beliefs about the use of anorexia for the person [pro-anorexia beliefs]; and a response of close others to the illness characterized by high expressed emotion and enabling of and accommodation to the illness). In this article, we describe how the model has been translated into a novel treatment for AN and the preliminary evidence supporting this. Implications for clinical practice and research are discussed.

Abstract
BACKGROUND The prevalence of overweight and obesity is increasing amongst women of child bearing age. The objective of this study was to investigate the views and attitudes of providers of antenatal care for women who have a body mass index (BMI) of 30 kg/m(2) and over. METHODS A qualitative study using focus groups was undertaken within the department of obstetrics and gynaecology at a large teaching hospital in south-eastern Australia. Three focus group discussions were held. One with hospital midwives (n=10), one with continuity of care midwives (n=18) and one with obstetricians (n=5). Data were analysed using Interpretative Phenomenological Analysis (IPA). FINDINGS Six dominant themes emerged: (1) obesity puts the health of mothers, babies and health professionals at risk; (2) overweight and obesity has become the norm; (3) weighing women and advising about weight gain is out of fashion; (4) weight is a sensitive topic to discuss; (5) there are significant barriers to weight control in pregnancy; and (6) health professionals and women need to deal with maternal obesity. These themes are drawn together to form a model representing current health care issues for these women. CONCLUSION Health professionals, who have a high BMI, can find it difficult to discuss obesity during antenatal visits with obese women. Specialist dietary interventions and evidence based guidelines for working with child-bearing women is seen as a public health priority by health care professionals.

Abstract
This review examines the theoretical rationale for conceiving of systematic information processing as a proximal mechanism for perseverative worry. Systematic processing is characterised by detailed, analytical thought about issue-relevant information, and in this way, is similar to the persistent, detailed processing of information that typifies perseverative worry. We review the key features and determinants of systematic processing, and examine the application of systematic processing to perseverative worry. We argue that systematic processing is a mechanism involved in perseverative worry because (1) systematic processing is more likely to be deployed when individuals feel that they have not reached a satisfactory level of confidence in their judgement and this is similar to the worrier's striving to feel adequately prepared, to have considered every possible negative outcome/detect all potential danger, and to be sure that they will successfully cope with perceived future problems; (2) systematic processing and worry are influenced by similar psychological cognitive states and appraisals; and (3) the functional neuroanatomy underlying systematic processing is located in the same brain regions that are activated during worrying. This proposed mechanism is derived from core psychological processes and offers a number of clinical implications, including the identification of psychological states and appraisals that may benefit from therapeutic interventions for worry-based problems.

Abstract
OBJECTIVE Social perception is a key aspect of social cognition which has so far not been investigated in eating disorders (ED). This study aimed to investigate social perception in individuals with anorexia nervosa (AN) and bulimia nervosa (BN). METHODS Outpatients with AN (restricting subtype [AN-R]: n=51; binge-purge subtype [AN-BP]: n=26) or BN (n=57) and 50 healthy control (HC) participants completed the Interpersonal Perception Task (IPT-15). This is an ecologically valid task, which consists of 15 video clips, depicting complex social situations relating to intimacy, status, kinship, competition and deception. The participants have to assess relationships between protagonists' based on non-verbal cues. RESULTS Overall, there was no difference between groups on the IPT total score and subscale scores. Group differences on the Intimacy subscale approached significance so post hoc comparisons were carried out. HCs performed significantly better than AN-R participants in determining the degree of intimacy between others. CONCLUSIONS Social perception is largely preserved in ED patients. Individuals with AN-R show impairments in identifying intimacy in social situations, this may be due to the lack of relationship experience. Further research into different aspects of social cognition is required to establish the link between interpersonal difficulties and ED psychopathology.

Abstract
People with Anorexia Nervosa (AN) have well-documented socio-emotional and neurocognitive impairments. As yet, little is known about their ability to solve problems in social situations, although a link with cognitive avoidance has been suggested. This study explored social problem-solving (SPS), using an experimental task. Secondly, the role of cognitive avoidance in SPS was investigated. Individuals with AN (n=31) and healthy controls (HC; n=39) completed the Social Problem Resolution Task which consists of problem scenarios involving awkward everyday social situations. Participants were asked to generate both the optimal solution and their personal solution. Solutions were rated in terms of how socially sensitive and practically effective they were. AN patients produced relatively poorer personal solutions compared to optimal solutions than HC participants and had higher scores on a measure of cognitive avoidance than the HC group. In AN patients, cognitive avoidance was partially associated with poor SPS. These findings suggest that whilst people with AN have no difficulty in generating socially sensitive and effective solutions to problems, but may have difficulty applying this knowledge to themselves.
