Emotional theory of mind and emotional awareness in recovered anorexia nervosa patients.

Anna Oldershaw; David Hambrook; Kate Tchanturia; Janet Treasure; Ulrike Schmidt

Objectives: To examine whether an impaired ability to infer emotion in people with autism spectrum disorder (ASD) and difficulty with emotional theory of mind (eToM) are limited to the ill state or if this condition is a stable deficit that persists with recovery in adults with anorexia nervosa (AN). This is in keeping with observations of similarities between the disorders. Methods: Twenty-four participants fully recovered from AN were compared against a sample of currently ill AN patients (n = 40) and healthy controls (HCs) (n = 47) on forced-choice tasks assessing emotion recognition, basic or advanced eToM in other people, using sensory stimuli and on a written task measuring eToM ability for the self as well as for others. Results: Recovered participants performed well on eToM tasks and were significantly better than currently ill patients at inferring emotions in the self and in others. However, participants recovered from AN had some slight impairment in emotion recognition relative to HCs, particularly when recognizing positive emotions. Conclusions: These findings indicate almost complete normalization of emotion recognition ability as well as the restoration of eToM in recovered patients, despite the observation of difficulties in both domains in currently ill patients. Findings suggest that similarities between AN and ASD in poor eToM are restricted to the currently ill AN state and such difficulties in AN may be a factor of starvation. AN = anorexia nervosa; ASD = autism spectrum disorder; recAN = recovered anorexia nervosa; HC = healthy control; ToM = theory of mind; eToM = emotional theory of mind; BMI = body mass index; IQ = intelligence quotient; ANCOVA = analysis of covariance.

OBJECTIVES Similarities have been noted between cognitive profiles of anorexia nervosa (AN) and autism spectrum disorders (ASD). However, there are no direct comparison studies. This study aimed to compare the cognitive profile of AN against published ASD data on tasks measuring empathy, executive function and central coherence. METHODS Currently ill AN outpatients (n = 40) were statistically compared against published ASD scores on Reading the Mind in the Eyes, Voice and Films tasks (assessing empathy), Wisconsin Card Sorting Task (WCST) (assessing executive function) and Embedded Figures Task (EFT) (assessing detail focus aspect of central coherence). RESULTS Cognitive profiles of the groups were statistically similar, except for differences in the relative patterns of empathy scores. CONCLUSIONS The cognitive profile in current AN resembles that of ASD with important clinical implications. Replication studies with planned comparisons, examination of the state-or trait-nature of AN profile and clarification of factors underpinning similarities are required in order to broaden understanding of both disorders.

OBJECTIVES. Difficulties in processing emotional states are implicated in the aetiology and maintenance of diverse health conditions, including anorexia nervosa (AN) and chronic fatigue syndrome (CFS). This study sought to explore distress tolerance, self-silencing, and beliefs regarding the experience and expression of emotions in individuals diagnosed with AN and CFS. These conditions were chosen for this study because their clinical presentation is characterized by physical symptoms, yet cognitive behavioural models suggest that emotional processing difficulties contribute to the aetiology and maintenance of both. DESIGN. A between-subjects cross-sectional design was employed. METHODS. Forty people with AN, 45 with CFS, and 48 healthy controls (HCs) completed the Distress Tolerance Scale (DTS), Silencing the Self Scale (STSS), Beliefs about Emotions Scale (BES), and measures of clinical symptomatology. RESULTS. Initial group comparisons found that both AN and CFS participants scored higher than HCs on a subscale measuring difficulties in distress tolerance. AN and CFS participants were also more likely to judge themselves by external standards, endorse statements reflecting a tendency to put the needs of others before themselves, and present an outwardly socially compliant image of themselves whilst feeling hostile within. Relative to HCs, AN participants reported more maladaptive beliefs regarding the experience of having negative thoughts and feelings and revealing these emotions to others, with CFS participants showing a non-significant trend in the same direction. After controlling for differences in age, anxiety, and depression the only significant difference to remain was that observed for the STSS care as self-sacrifice subscale. More maladaptive beliefs about the experience and expression of emotions were associated with greater degree of eating disorder symptomatology in the AN group. CONCLUSIONS. Differences in emotional processing are present in AN and CFS compared to HCs, with some disorder-specific variation, and may be associated with greater clinical symptomatology. These findings support current explanatory models of both AN and CFS, and suggest that emotional processing should be addressed in the assessment and treatment of individuals with these illnesses.

Empathy, systemizing, and autistic traits in anorexia nervosa: a pilot study.

David Hambrook; Kate Tchanturia; Ulrike Schmidt; Tamara Russell; Janet Treasure

OBJECTIVES This pilot study examined whether patients with anorexia nervosa (AN) would display an empathizing-systemizing psychometric profile similar to that found in autism spectrum disorders (ASD), and whether people with AN would score highly on a measure of autistic traits. METHOD Self-report measures of empathy, systemizing, and autistic traits were administered to 22 female AN patients and 45 female healthy controls (HC). RESULTS AN patients and HCs did not differ significantly in their self-reported empathy and systemizing. AN patients scored significantly higher than HCs on the autism-spectrum quotient. CONCLUSIONS Replication of these findings is required with larger samples and more sensitive measures.

Emotional intelligence in anorexia nervosa: Is anxiety a missing piece of the puzzle?

David Hambrook; Gary Brown; Kate Tchanturia

Problematic emotional processing has been implicated in the genesis and maintenance of anorexia nervosa (AN). This study built on existing research and explored performance-based emotional intelligence (EI) in people with AN. The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) was administered to 32 women diagnosed with AN and 32 female healthy controls (HC). Compared to HC women, the AN group demonstrated significantly lower total EI scores and poorer ability to understand how emotions can progress and change over time. Despite scores within the broadly average range compared to published EI norms, there was a general pattern of poorer performance in the AN sample. Self-reported anxiety symptoms were the strongest predictor of EI, over and above a diagnosis of AN. This study adds to the literature documenting the socioemotional phenotype of AN, suggesting this group of individuals may find it relatively difficult to carry out accurate reasoning about emotions, and to use emotions and emotional knowledge to enhance thought. Anxiety was highlighted as a putative variable partially explaining why people with AN demonstrated lower EI compared to controls. Implications for further research are discussed, including the need to explore the specificity of EI difficulties in AN using larger samples and additional control groups.

Why Study Positive Emotions in the Context of Eating Disorders

Kate Tchanturia; Marcela Marin Dapelo; Amy Harrison; David Hambrook

Experimental research, supported by systematic reviews, establishes that people with eating disorders have emotional difficulties in terms of recognising, regulating and expressing their emotions. These emotional difficulties contribute to poor social functioning and problems with relationships. The existing literature includes a broad range of studies, many of which have utilised self-report measures, but experimental studies of emotions in eating disorders are still limited. The primary aim of this paper is to highlight gaps in the clinical research on emotions in eating disorders, focusing on experimental investigations from our lab and highlighting potentially useful future directions for further basic research and its translation into new developments in treatment and prevention. Recent findings using experimental paradigms to study the expression of emotions along with neuroimaging research exploring differences in facial emotion processing are discussed, and clinical implications are presented.

Background: Difficulties with social function have been reported in chronic fatigue syndrome (CFS), but underpinning factors are unknown. Emotion recognition, theory of mind (inference of anothers mental state) and ‘emotional’ theory of mind (eToM) (inference of anothers emotional state) are important social abilities, facilitating understanding of others. This study examined emotion recognition and eToM in CFS patients and their relationship to self-reported social function. Methods: CFS patients (n = 45) and healthy controls (HCs; n = 50) completed tasks assessing emotion recognition, basic or advanced eToM (for self and other) and a self-report measure of social function. Results: CFS participants were poorer than HCs at recognising emotion states in the faces of others and at inferring their own emotions. Lower scores on these tasks were associated with poorer self-reported daily and social function. CFS patients demonstrated good eToM and performance on these tasks did not relate to the level of social function. Conclusions: CFS patients do not have poor eToM, nor does eToM appear to be associated with social functioning in CFS. However, this group of patients experience difficulties in emotion recognition and inferring emotions in themselves and this may impact upon social function.

A pilot study exploring Machiavellianism in anorexia nervosa

David Hambrook; Kate Tchanturia

Machiavellianism has not previously been systematically explored in the eating disorders. This personality dimension involves the social cognitive processes required to identify others’s intentions and the use of strategies to deceive and manipulate others. Individuals suffering with Anorexia Nervosa (AN) often try to conceal their disorder through the use of deceptive strategies. In this study we explore Machiavellianism in 22 female AN patients and 41 female healthy controls (HCs). AN patients and HCs did not differ significantly in their self-reported Machiavellianism, but both groups did score highly in this domain. Possible explanations for these results are discussed.

BACKGROUND Lesbian, gay and bisexual individuals experience more anxiety and depression than heterosexual people. Little is known about their comparative treatment response to psychological interventions. AIMS To compare sociodemographic/clinical characteristics and treatment outcomes across sexual orientation groups, for adults receiving primary care psychological interventions from Improving Access to Psychological Therapies (IAPT) services in London, adjusting for possible confounders. METHOD Data from 188 lesbian women, 222 bisexual women, 6637 heterosexual women, 645 gay men, 75 bisexual men and 3024 heterosexual men were analysed from pre-treatment and last treatment sessions. Males and females were analysed separately. RESULTS Before treatment, lesbian and bisexual women were more likely to report clinical levels of impairment (Work and Social Adjustment Scale) than heterosexual women; there were no significant differences in depression (PHQ-9) or anxiety (GAD-7). Bisexual men were more likely to meet depression caseness than gay men but less likely to meet anxiety caseness than gay or heterosexual men. Compared with heterosexual women, lesbian and bisexual individuals showed smaller reductions in depression and impairment, controlling for age, ethnicity, employment, baseline symptoms, number of sessions and intervention type. Bisexual women experienced significantly smaller reductions in anxiety than heterosexual women and were less likely to show recovery or reliable recovery. There were no significant differences in treatment outcomes between gay, bisexual and heterosexual men. CONCLUSIONS Reasons for poorer outcomes in lesbian and bisexual women require investigation, for example lifetime trauma or stigma/discrimination regarding gender or sexual orientation in everyday life or within therapy services.
