Alexithymia and emotional awareness in anorexia nervosa: time for a shift in the measurement of the concept?

Shared and distinct aberrations in frontal-striatal system functional patterns among patients with irritable bowel syndrome and major depressive disorder

BACKGROUND

Considering the high comorbidity, shared risk factors, and genetic pathways between irritable bowel syndrome (IBS) and major depressive disorder (MDD), we hypothesized that there would be both shared and disorder-specific alterations in brain function.

METHODS

A total of 39 IBS patients, 39 MDD patients, and 40 healthy controls (HCs) were enrolled and matched for sex, age, and educational level. All subjects underwent resting-state functional MRI. The clinical variables of anxiety, depression, gastrointestinal symptoms and alexithymia were recorded. The 12 subregions of the striatum were employed as seeds to assess their functional connectivity (FC) with every voxel throughout the whole brain.

RESULTS

Compared to HC, IBS and MDD patients exhibited aberrant frontal-striatal circuitry. We observed a common decrease in FC between the dorsal striatum and regions of the hippocampus, sensorimotor cortex, and prefrontal cortex (PFC) in both IBS and MDD patients. Patients with IBS exhibited disorder-specific decreases in FC within the striatum, along with reduced connectivity between the ventral striatum and sensorimotor cortex. In contrast, MDD patients showed disorder-specific hyperconnectivity in the medial PFC-limbic system. Receiver operating characteristic curve analysis showed that frontal-striatal FC values could serve as transdiagnostic markers of IBS and MDD. Within the IBS group, striatal connectivity was not only negatively associated with weekly abdominal pain days but also negatively correlated with the levels of anxiety and alexithymia.

CONCLUSIONS

This exploratory analysis indicated that patients with IBS and MDD exhibited both shared and disorder-specific frontal-striatal circuit impairments, potentially explaining both comorbidity and distinct phenotypes.

Anorexia nervosa through the lens of a severe and enduring experience: 'lost in a big world'

BACKGROUND

Severe and enduring anorexia nervosa (SE-AN), is a serious and persistent illness, despite 'state of the art' treatment. Criteria have been theoretically proposed, but not tested, and may not adequately capture illness complexity, which potentially inhibits treatment refinements. The clinical reality of death as an outcome for some people who experience SE-AN (1 in 20) and broadening access to voluntary assisted dying, further complicates the field, which is undeveloped regarding more fundamental concepts such as nosology, treatment, recovery definitions and alternative conceptualisations of SE-AN. The present paper is in response to this and aims to build upon qualitative literature to enhance phenomenological understandings of fatal SE-AN.

METHOD

A published book, being the legacy of a 32-year-old professional artist offers a rich account of a life lived with AN, for 18 years with continuous treatment. A polysemous narrative via the interrelationship between the languages of the artist's words and visual art is translated via interpretative phenomenological analysis (IPA), offering rich insight into the SE-AN experience.

FINDINGS

The process of analysis induced three superordinate themes (1) Disappearing Self (2) Dialectical Dilemma (3) Death and Dying: Finding Meaning. Two cross cutting themes traversed these themes: (a) Colour and (b) Shifting Hope, where the former produced a visual representation via the 'SE-AN Kaleidoscope'. Collectively the themes produce a concept of SE-AN, grounded in the data and depicted visually through the artist's paintings.

CONCLUSIONS

The picture of SE-AN revealed in the analysis extends upon conceptualisations of SE-AN, highlighting key processes which are thus far under explored. These factors are implicated in illness persistence eliciting opportunities for further research testing including diagnostic considerations and treatment directions. In SE-AN, distorted body image extends to a global distortion in the perception of self. Additional criteria for the severe and enduring stages of illness related to (1) self and identity processes (2) measures of 'global impoverishment' across life domains are proposed for consideration in the future testing of putative defining features of SE-AN.

Exploring the associations between early maladaptive schemas and impulsive and compulsive buying tendencies

The main purpose of this preliminary study was to investigate a potential relationship between early maladaptive schemas (EMSs) and impulsive and compulsive buying tendencies in a sample of young adults (college students). This research adds to the cognitive perspective of consumer behavior that the cognitive schemas putatively associated with early experiences may have a strong impact on impulsive and compulsive buying. Data was obtained from 365 participants in a cross-sectional study design. Participants completed an online survey with the following instruments: Young Schema Questionnaire; Impulsive Buying Tendency Measurement Scale; Richmond Compulsive Buying Scale; and Hospital Anxiety and Depression Scale. Using multiple linear hierarchical regressions, we confirmed that the domain of over vigilance and inhibition schemas was positively associated with impulsive and compulsive buying tendencies, while an opposite association was found for the domain of impaired limits. Being a female was also a predictor of impulsive buying and compulsive buying. The results were discussed in terms of the coping mechanisms to deal with negative emotions, as a way to obtain rewards, or as a way to escape painful self-awareness. Other mechanisms related to the internalization of perfectionist expectations and the propensity to shame were also explored.

What about males? Exploring sex differences in the relationship between emotion difficulties and eating disorders

OBJECTIVE

While eating disorders (EDs) are more commonly diagnosed in females, there is growing awareness that men also experience EDs and may do so in a different way. Difficulties with emotion processing and emotion regulation are believed to be important in EDs, but as studies have involved predominantly female samples, it is unclear whether this is also true for males.

METHODS

In a sample of 1604 participants (n = 631 males), we assessed emotion processing and emotion regulation in males with EDs (n = 109) and compared results to both females with EDs (n = 220) and males from the general population (n = 522). We also looked at whether emotion processing and emotion regulation difficulties predicted various aspects of eating psychopathology and whether this was moderated by sex. We assessed emotion processing with the Toronto Alexithymia Scale, emotion regulation with the Difficulties in Emotion Regulation Scale and the Emotion Regulation Questionnaire, and eating psychopathology with the Eating Disorder Examination Questionnaire.

RESULTS

We found that males with ED, like their female counterparts, suffered from emotion processing and emotion regulation deficits. We did find some sex differences, in that males with EDs tended to report more difficulties with their emotions as well as a more externally oriented thinking style compared to females with EDs. Difficulties with emotion processing and emotion regulation were strongly predictive of various aspects of eating psychopathology in both sexes. Importantly, we found that sex moderated the relationship between cognitive reappraisal and eating restraint. As such, low use of reappraisal was found to be associated with higher levels of restraint in females but not in males.

DISCUSSION

Difficulties with emotion processing and emotion regulation are associated with eating psychopathology in both males and females. Reappraisal was not found to be associated with reduced eating psychopathology in males, suggesting a cautious approach to interventions targeting this strategy. Research around explanatory mechanisms and interventions must adopt a broader viewpoint including those that are traditionally overlooked in EDs.

Family, friends, and feelings: the role of relationships to parents and peers and alexithymia in adolescents with anorexia nervosa

BACKGROUND

Anorexia nervosa (AN) is associated with impairments in socio-emotional functioning, including difficulties in interpersonal relationships as well as alexithymia (difficulties identifying and describing one's emotions). Although the onset of the disorder is mostly in adolescence, a developmental period in which interpersonal relationships to parents as well as peers undergo major changes, only few studies have investigated the quality of interpersonal relationships in adolescent AN patients. Furthermore, the mechanisms linking poor relationship quality to eating disorder psychopathology are not yet clarified, albeit some research suggests that alexithymia might play a pivotal role. The aims of the present study were investigating the quality of interpersonal relationships to parents and peers in adolescents with AN compared to healthy adolescents as well as exploring the mediating role of alexithymia in the association between relationship quality and eating disorder symptoms.

METHODS

Self-report questionnaires were used to assess relationship quality (Inventory of Parent and Peer Attachment) and alexithymia (Toronto Alexithymia Scale) in 12-18 year old female adolescents with AN (n = 35) in comparison to healthy adolescents (n = 40).

RESULTS

Adolescents with AN reported lower relationship quality to both of their parents and to peers compared to healthy controls. Relationship quality scores were negatively correlated to alexithymia as well as eating disorder symptoms. Alexithymia fully meditated the association between eating disorder symptoms and relationship quality to parents and partially mediated the association between eating disorder symptoms and relationship quality to peers.

CONCLUSION

The results indicate difficulties in interpersonal relationships among adolescents with AN and emphasize the role of peer relationships for adolescents' eating disorder psychopathology. Alexithymia seems to play an important role in explaining the link between quality of relationships and eating disorder psychopathology. Results suggest that treatment should not only focus on family relationships but also address relationships to peers as well as adolescents' competence in identifying and dealing with their emotions.

Evaluation of the Affect School as supplementary treatment of Swedish women with eating disorders: a randomized clinical trial

BACKGROUND

Despite solid research there remains a large group of patients with eating disorders who do not recover. Emotion dysregulation has been shown to be a feature in the different eating disorders. A manualized group intervention developed in Sweden, the Affect School, aims to enhance emotional awareness and the ability to perceive and express emotions.

AIM

This study aimed to test the hypothesis that participation in the Affect School as a complement to ordinary eating disorder treatment would enhance awareness and regulation of emotions and reduce alexithymia and cognitive eating disorder symptoms in a sample of patients with eating disorders at a Swedish specialized outpatient clinic.

METHOD

Forty patients with various eating disorders were randomized to either participation in the Affect School as a supplement to treatment as usual (TAU), or to a TAU control group. Participants were assessed with the Eating Disorder Examination Questionnaire, the Deficits in Emotion Regulation Scale-36, and the Toronto Alexithymia Scale-20 at start, end of intervention, and at the 6- and 12-month follow-ups.

RESULTS

No significant differences were observed post-treatment but Affect School participants had improved significantly more than controls on eating disorder cognitions and behaviours and emotion dysregulation at the 6- and 12-month follow-ups and had significantly less alexithymia at the 6-month follow-up.

CONCLUSION

Difficulties with emotion recognition and/or regulation can complicate fulfilment of personal needs and obstruct communication and relationships with others. The present study indicates that adding Affect School group sessions to regular treatment enhances emotional awareness and emotion regulation and decreases eating disorder symptoms and alexithymia. Patients with eating disorder diagnoses have described problems with emotional management, for example: lower emotional awareness and difficulties in using adaptive emotional regulatory strategies compared to people without eating disorders. It has been suggested that interventions aiming at enhancing emotional awareness and acceptance would be beneficial in treatment. In the present study we explored whether adding the Affect School to regular treatment would enhance awareness and regulation of emotions and decrease eating disorder symptoms. Forty women with an eating disorder were randomly allocated to either an additional participation in a group treatment for 8 weeks or usual treatment only. The treatment contained education on different affects such as joy, fear, interest, shame, anger, disgust, and worry. The education was followed by discussions on own experiences. Participants filled in self-assessment forms that measured eating disorder symptoms, emotional recognition, and emotion regulation before the start and at the end of the group treatment, and after 6 and 12 months respectively. The results when comparing the two groups suggested that the Affect School could be an effective additional treatment. Participants in the Affect School improved their scorings but the change took time and did not show until at the 6- and 12 months follow-ups.

Intact neural and behavioral correlates of emotion processing and regulation in weight-recovered anorexia nervosa: a combined fMRI and EMA study

Altered emotion processing and regulation mechanisms play a key role in eating disorders. We recently reported increased fMRI responses in brain regions involved in emotion processing (amygdala, dorsolateral prefrontal cortex) in acutely underweight anorexia nervosa (AN) patients while passively viewing negatively valenced images. We also showed that patients' ability to downregulate activity elicited by positively valenced pictures in a brain region involved in reward processing (ventral striatum) was predictive of worse outcomes (increased rumination and negative affect). The current study tries to answer the question of whether these alterations are only state effects associated with undernutrition or whether they constitute a trait characteristic of the disorder that persists after recovery. Forty-one individuals that were weight-recovered from AN (recAN) and 41 age-matched healthy controls (HC) completed an established emotion regulation paradigm using negatively and positively valenced visual stimuli. We assessed behavioral (arousal) and fMRI measures (activity in the amygdala, ventral striatum, and dorsolateral prefrontal cortex) during emotion processing and regulation. Additionally, measures of disorder-relevant rumination and affect were collected several times daily for 2 weeks after scanning via ecological momentary assessment. In contrast to our previous findings in acute AN patients, recAN showed no significant alterations either on a behavioral or neural level. Further, there were no associations between fMRI responses and post-scan momentary measures of rumination and affect. Together, these results suggest that neural responses to emotionally valenced stimuli as well as relationships with everyday rumination and affect likely reflect state-related alterations in AN that improve following successful weight-recovery.

Meta-Analysis of the Associations Among Constructs of Intrapersonal Emotion Knowledge

To better define the boundaries of conceptually overlapping constructs of intrapersonal emotion knowledge (EK), we examined meta-analytic correlations among five intrapersonal EK-related constructs (affect labelling, alexithymia, emotional awareness, emotional clarity, emotion differentiation) and attention to emotion. Affect labelling, alexithymia, and emotional clarity were strongly associated, and they were moderately associated with attention to emotion. Alexithymia and emotional awareness were weakly associated, and emotion differentiation was unrelated with emotional clarity. Sample characteristics and measures moderated some of the associations. Publication bias was not found, except for the alexithymia-emotional awareness association. This study helped to clarify the extent to which similarly defined constructs overlap or are distinct, which can inform our decision to adequately label important constructs and employ corresponding measures.

Associations between socioemotional alterations, quality of life, and social functioning in multiple sclerosis: A scoping review

The main aim of the present scoping review is to systematically review the available studies that investigated the associations between socioemotional alterations (i.e., social cognition impairments/alexithymia/difficulties in emotion regulation) and both reduced QoL and social functioning in patients with Multiple Sclerosis (MS). The articles were selected from the PubMed, PsycINFO, and Scopus databases. The main exclusion criteria were qualitative studies, articles that did not use validated instruments, and studies that did not investigate the association between socioemotional skills and QoL/social functioning in MS. Of the eight studies fulfilling the inclusion criteria, six found significant associations between social cognitive and emotion regulation abilities and QoL/social functioning in patients with MS, while two found no significant relationships particularly between the performance on social cognition tasks and QoL measures. Overall, the majority of findings seem to highlight that socioemotional alterations contribute to impaired QoL and social functioning in MS. However, given the still limited evidence, future studies are needed to replicate and confirm the available results, paying attention to two principal aspects: the use of standardized and ecological tasks for the assessment of social cognition skills and the recruitment of samples involving patients with different types of MS.

Construct validity of the Levels of Emotional Awareness Scale among women high in eating disorder symptoms: a cross-sectional study

PURPOSE

The Levels of Emotional Awareness Scale (LEAS), a measure of the ability to identify and describe one's own and others' emotions, may complement work with women with disordered eating symptoms. The study purpose was to (a) examine differences in hand (LEAS) versus computerized (e-LEAS) scoring methods and (b) examine the e-LEAS' psychometric properties, including convergent and discriminant validity, among women endorsing eating disorder symptoms.

METHODS

Forty women (ages 18-21) scoring high on a self-report measure of disordered eating symptoms completed the LEAS and measures of convergent validity including a self-report measure of alexithymia (the perceived ability to identify and describe one's own emotions) and a measure of facial affect recognition as well as discriminant validity, including affect and facial memory. Inter-rater reliability was assessed via a two-way mixed effects model and correlations between the LEAS and the study constructs were examined.

RESULTS

Computerized scoring (e-LEAS) offered benefits over hand scoring and correlations between LEAS and e-LEAS were statistically significant. Better total emotional awareness scores on the e-LEAS were significantly associated with more perceived difficulty identifying and describing emotions. Better total emotional awareness scores were also significantly associated with better facial memory and greater depression scores. The e-LEAS showed weak associations with facial affect recognition.

CONCLUSION

The e-LEAS offers practical advantages over the LEAS in the assessment of emotional awareness among women endorsing eating disorder symptoms. Results suggest that the e-LEAS measures the ability to describe emotional experiences in oneself and others, but not facial affect recognition.

Just like fireworks in my brain - a Swedish interview study on experiences of emotions in female patients with eating disorders

BACKGROUND

Patients with eating disorders have reported poorer emotional awareness, more emotional suppression, less use of adaptive emotional regulation strategies, and more use of maladaptive emotional regulation strategies compared to people in healthy control groups.

AIM

To explore experiences of emotions by a transdiagnostic sample of patients with eating disorders.

METHOD

Nine patients with different eating disorder diagnoses at an eating disorder outpatient clinic in Sweden were interviewed for their thoughts on emotions. The interviews were analyzed with Thematic Analysis.

RESULT

Four themes were constructed: "Not knowing what one feels", "Switch off, run away, or hide behind a mask", "Emotions in a lifelong perspective", and "Using eating behaviours to regulate emotions". The patients described uncertainty regarding whether they experienced emotions correctly. They described how they tried to avoid difficult emotions through suppressive strategies and eating disorder behaviour. All described strategies were inefficient and all emotions were experienced as problematic, even joy. Since joy was used as a mask, the real experience of happiness was lost and mourned.

CONCLUSION

All kinds of emotions were considered problematic to experience, but shame, fear, and sadness were considered worst. It is difficult to know if the emotional difficulties preceded an eating disorder, however such difficulties may have increased as a result of the eating disorder.

Alexithymia may explain the relationship between autistic traits and eating disorder psychopathology

BACKGROUND

Autistic people are disproportionately vulnerable to anorexia nervosa and other eating disorders (ED), and within the general population, autistic traits correlate with ED psychopathology. A putative mechanism which may underpin this heightened risk is alexithymia, a difficulty identifying and describing emotional states which is observed in both autism and ED. In two experiments with independent non-clinical samples, we explored whether alexithymia might mediate the heightened risk of eating psychopathology in individuals high in autistic traits.

METHODS

Our first experiment used the PROCESS macro for SPSS to examine relationships between alexithymia (measured by the Toronto Alexithymia Scale (TAS-20)), autistic traits (autism quotient (AQ)), and eating psychopathology (Eating Attitudes Test (EAT-26)) in 121 participants. Our second experiment (n = 300) replicated and furthered this analysis by examining moderating effects of sex and controlling for anxiety and depression as covariates. We also included an additional performance-based measure of alexithymia, the Levels of Emotional Awareness Scale (LEAS).

RESULTS

Study 1 suggested that TAS-20 scores mediated the relationship between heightened autistic traits and eating psychopathology. Replication and further scrutiny of this finding, in study 2, revealed that this mediation effect was partial and specific to the female participants in this sample. The mediation effect appeared to be carried by the difficulty identifying feelings subscale of the TAS-20, even when depression and anxiety were controlled for. LEAS scores, however, were not significantly related to autistic traits or eating psychopathology.

LIMITATIONS

Cross-sectional data prevents any conclusions around the direction and causality of relationships between alexithymia, autistic traits, and eating psychopathology (alongside depression and anxiety), necessitating longitudinal research. Our non-clinical sample was predominantly Caucasian undergraduate students, so it remains to be seen if these results would extrapolate to clinical and/or autistic samples. Divergence between the TAS-20 and LEAS raises crucial questions regarding the construct validity of these measures.

CONCLUSIONS

Our findings with respect to autistic traits suggest that alexithymia could partially explain the prevalence of ED in autistic people and may as such be an important consideration in the pathogenesis and treatment of ED in autistic and non-autistic people alike. Further research with clinical samples is critical to explore these ideas. Differences between men and women, furthermore, emphasize the importance of looking for sex-specific as well as generic risk factors in autistic and non-autistic men and women.

Differences in alexithymia, emotional awareness, and facial emotion recognition under conditions of self-focused attention among women with high and low eating disorder symptoms: a 2 x 2 experimental study

BACKGROUND

Women with eating disorders generally perform more poorly on measures of alexithymia, defined as difficulty identifying and describing emotions, and theory of mind, or the ability to infer what others are thinking and feeling. The extent to which these abilities may be influenced by variables such as self-focused attention, or directing attention toward internally generated information, has yet to be investigated. Thus, the purpose of the present study was to examine differences between women high and low in disordered eating symptoms on measures of emotional awareness and facial affect recognition under conditions of high and low self-focused attention.

METHODS

University women scoring high or low on a measure of disordered eating (n = 79) were randomly assigned to a condition of high or low self-focused attention. Outcomes included alexithymia (self-rated ability to identify and describe emotions), emotional awareness (ability to describe the emotions of oneself and others), and facial affect recognition. Scores on a measure of negative affect were statistically controlled.

RESULTS

Women with high disordered eating symptom scores rated themselves as having more difficulties identifying, but not describing emotions after controlling for negative affect, but demonstrated greater difficulties describing their own and others' emotions on a measure of emotional awareness. In the self-focused attention condition, women scored lower on self emotional awareness and were quicker to identify expressions of negative facial affect regardless of eating disorder symptom status than women in the non-self-focused attention condition. There were no significant interactions between eating disorder status and self-focused attention.

CONCLUSIONS

Further examination of different types of emotion recognition and description in oneself and others as well as processes that may influence these abilities is warranted.

Re-inhabiting one's body: A pilot study on the effects of dance movement therapy on body image and alexithymia in eating disorders

BACKGROUND

Body image disturbance and alexithymia are two core aspects of Eating Disorders (EDs). However, standard treatments for EDs do not include specific techniques to approach these issues on a bodily level. This pilot study evaluated the effects of a Dance Movement Therapy (DMT) intervention on body image and alexithymia in patients with EDs, and also explored their experience of the therapeutic process.

METHOD

14 patients with EDs were recruited from a private clinic. Seven were assigned via quasi-randomization to the DMT group and the others (n = 5) continued their treatment as usual. The length of the intervention was 14 weeks. All participants completed the Multidimensional Body Self Relations Questionnaire (MBSRQ) and the Toronto Alexithymia Scale (TAS-20) at the beginning and at the end of the intervention. Additionally, the DMT group wrote reflective diaries about their experience at the end of each session, which were analyzed using qualitative methods.

RESULTS

Between the pre- and post-intervention, the participants of the DMT group significantly improved in Body Areas Satisfaction (effect size: 0.95) and Appearance Evaluation (effect size: 1.10), and they decreased significantly in Appearance Orientation (effect size: 1.30). A decrease in Overweight Preoccupation was observed (effect size: 0.75), however this was not statistically significant. The control group did not show significant changes in any of the MBSRQ subscales. Neither the DMT group nor the control group improved significantly in the alexithymia scores. The qualitative analysis revealed valuable insights into the participants' processes throughout the sessions. In general, participants received the DMT intervention positively. They reported improvements in their mood states and an increase in their self-awareness. They also appreciated the relationship with the group and the therapist.

CONCLUSION

These results indicate that DMT might be a complementary treatment option for EDs, as it may be able to address body image issues more effectively than verbal therapies. More studies with larger samples are needed to confirm these promising preliminary results.

The mentalization profile in patients with eating disorders: a systematic review and meta-analysis

Context: Patients with eating disorders (EDs) may have a lower mentalization ability. To the best of our knowledge, no meta-analysis has so far addressed the multidimensional mentalization profile within these patients.Objective: To summarize the existing evidence of the mentalization profile and its association with EDs.Data sources: We searched for articles in PsychINFO, Embase and PubMed using the search terms mentalization, reflective function, adult attachment interview, alexithymia, Toronto Alexithymia Scale, eye test, Reading the Mind in the Eyes Test, Theory of Mind, mind-mindedness, mind-blindness, facial expression recognition, metacognition, ED, anorexia nervosa (AN) and bulimia nervosa (BN).Studies included: Quantitative studies including diagnosed patients with an ED, healthy controls (HCs) and relevant test methods.Data synthesis: Forty-four studies were included. Nine studies were eligible for the meta-analysis. Significantly lower mentalization ability about oneself was found in patients with an ED when compared to HCs. Groups were more comparable when dealing with mentalization ability of others. Non-significant but clinically relevant results include a tendency for a lower mentalization ability in patients with AN compared to patients with BN.Conclusion: The mentalization profile is complex and varies across dimensions of mentalization in patients with an ED. Different degrees of mentalization between various EDs were found, implying the necessity for further research on mentalization profiles in different ED diagnoses. The sparse existing literature was a limitation for this meta-analysis, emphasizing that further research on the mentalization profile in patients with EDs is needed.

Cognitive and Emotional Empathy in Anorexia Nervosa: The Role of Attachment Insecurity, Intrapersonal, and Interpersonal Emotional Competences

The present research examined a model that evaluates the mediating role of both intrapersonal and interpersonal emotional competences (ECs) between attachment insecurity and the cognitive and emotional dimensions of empathy in patients with anorexia nervosa (AN). Women with AN completed the Experiences in Close Relationships Scale, the Profile of Emotional Competence, the Interpersonal Reactivity Index, the State-Trait Anxiety Inventory, and the Beck Depression Inventory. The results revealed that intrapersonal EC mediated the relationships between attachment insecurity (i.e., attachment anxiety and attachment avoidance) and emotional empathy in patients with AN. Importantly, a high emotional empathy in AN was associated with increased depression and anxiety symptoms. The results also indicated that a high level of attachment avoidance was indirectly associated with lower cognitive empathy through lower levels of interpersonal EC in AN. The present study emphasizes the importance of differentiating affective empathy from cognitive empathy and suggests clinical interventions in patients with AN.

Neuro-cognitive correlates of alexithymia in patients with circumscribed prefrontal cortex damage

Alexithymia has been extensively reported in studies of psychiatric patients. However, little attention has been paid regarding its occurrence in the context of patients with circumscribed prefrontal cortex lesions. Moreover, the neuro-cognitive impairments that lead to alexithymia remain unclear and limited numbers of studies have addressed these issues. The authors investigated the impact of prefrontal cortex lesions on alexithymia and its neuro-cognitive correlates in a population of 20 patients with focal frontal lesions, 10 patients with parietal lesions and 34 matched control participants. Alexithymia was screened using the Toronto Alexithymia Scale (TAS-20) and executive functions were assessed using a large battery of executive tasks that address inhibition, flexibility and the planning process. Results showed that patients with prefrontal cortex damage showed significantly increased difficulty in facets of identifying feelings (DIF) and externally oriented thinking (EOT) on TAS-20, compared to parietal patients and control participants. Moreover, both correlation and regression analysis revealed that higher alexithymia levels on the three facets of TAS-20 were consistently but differentially associated with impairment in inhibition, flexibility and planning tasks for frontal patients and both control groups. These findings provide clinical evidence of the implication of prefrontal cortex damage and executive control in alexithymia. Our results were also discussed in the light of the cognitive appraisal concept as a mechanism involved in emotion episode processing. This study suggests that increased neuropsychological attention should be directed to the relation between the neuro-cognitive model of executive functions and cognitive appraisal theory in processing emotion.

Emotion regulation across eating pathology: A meta-analysis

The goal of this meta-analysis was to examine the associations between specific emotion regulation abilities (emotional awareness, emotional clarity) and strategies (acceptance of emotions, reappraisal, problem-solving, rumination, avoidance of emotions, and suppression), and eating pathology. A total of 96 studies and 239 effect sizes were included in the analysis. Relations between global and specific emotion regulation abilities and strategies and eating disorders and eating-related symptoms were examined. Results indicated medium-to-large effect sizes for the associations between adaptive emotion regulation and eating disorder and eating-related symptoms, and medium-to-large effect sizes for the associations between maladaptive emotion regulation and eating disorders and eating-related symptoms. In terms of specific emotion regulation strategies, large magnitude of associations were identified for the relations between lack of emotional awareness, clarity, acceptance, reappraisal, problem-solving, and eating disorders. Rumination, avoidance of emotions, and suppression also showed large associations with anorexia nervosa and bulimia nervosa. Overall, emotion regulation did not differ across eating disorders, a finding supporting the transdiagnostic character of emotion regulation problems in eating pathology. These findings have important theoretical and practical implications for prevention and intervention programs.

An examination of emotion dysregulation in maladaptive perfectionism

Maladaptive perfectionism has been shown to be associated with undesirable outcomes, such as elevated negative emotions and psychopathological traits. Perhaps unsurprisingly, there is preliminary evidence that maladaptive perfectionism is also related to emotion dysregulation. However, the nature of emotion dysregulation in perfectionism has not been characterized. In this review, Gross and Jazaieri's (2014) clinically-informed framework of emotion dysregulation is used to review the evidence of emotion dysregulation in maladaptive perfectionism. Specifically, this paper reviews evidence of problematic emotional experiences and unhelpful emotion regulation strategies in maladaptive perfectionism and discusses how poor emotional awareness and emotion regulation goals may also contribute to emotion dysregulation. A conceptual model of these components of emotion dysregulation in maladaptive perfectionism is proposed in which heightened negative affect in response to threatened perfectionistic standards is posited to be at the core of emotion dysregulation, and implicit and explicit unhelpful emotion regulation strategies and poor emotion regulation goals are suggested to contribute to further dysregulation and elevated negative affect. Clinical implications, limitations in the extant research, and future directions are discussed.

Exploring the role of emotional intelligence on disorder eating psychopathology

PURPOSE

This study aims to explore the role of Emotional Intelligence (EI) and specific facets that may underpin the aetiology of disordered eating attitudes and behaviours, as a means to understand what aspects of these deficits to target within treatments.

METHODS

Participants were recruited from the UK and Ireland. Among the sample of 355 participants, 84% were women and 16% were men. Regarding age, 59% were between 18 and 29, 30% were between 30 and 49, and 11% were 50 or older. Using a cross-sectional design, participants completed the Schutte Self-Report Emotional Intelligence Test to measure levels of trait EI and The Eating Attitudes Test (EAT-26) as a measure of eating disorder risk and the presence of disordered eating attitudes.

RESULTS

EAT-26 scores were negatively correlated with total EI scores and with the following EI subscales: appraisal of own emotions, regulation of emotions, utilisation of emotions, and optimism. Also, compared to those without an eating disorder history, participants who reported having had an eating disorder had significantly lower total EI scores and lower scores on four EI subscales: appraisal of others emotions, appraisal of own emotions, regulation of emotions, and optimism.

CONCLUSIONS

Considering these findings, EI (especially appraisal of own emotions, regulation of emotions, and optimism) may need to be addressed by interventions and treatments for eating disorders.

Cognitive and Affective Empathy in Eating Disorders: A Systematic Review and Meta-Analysis

Background: Recent models of eating disorders (EDs) have proposed social and emotional difficulties as key factors in the development and maintenance of the illness. While a number of studies have demonstrated difficulties in theory of mind and emotion recognition, little is known about empathic abilities in those with EDs. Further, few studies have examined the cognitive-affective empathy profile in EDs. The aim of this systematic review and meta-analysis was to provide a synthesis of empathy studies in EDs, and examine whether those with EDs differ from healthy controls (HC) on self-reported total, cognitive, and affective empathy. Methods: Electronic databases were systematically searched for studies using self-report measures of empathy in ED populations. In total, 17 studies were identified, 14 of which could be included in the total empathy meta-analysis. Eight of the 14 studies were included in the cognitive and affective empathy meta-analyses. Results: Meta-analyses showed that while total empathy and affective empathy scores did not differ between those with anorexia nervosa (AN) and HC, those with AN had significantly lower cognitive empathy scores compared to HCs (small effect size). Meta-analyses of Interpersonal Reactivity Index sub-scores revealed that AN had significantly lower Fantasy scores than HC (small effect size), indicating that those with AN have more difficulty in identifying themselves with fictional characters. Only 3 studies examined empathy in those with bulimia nervosa (BN) or binge eating disorder (BED). Conclusions: The lowered cognitive empathy and intact affective empathy profile found in AN is similar to that found in other psychiatric and neurodevelopmental conditions, such as autism spectrum disorder (ASD). These findings add to the literature characterizing the socio-emotional phenotype in EDs. Future research should examine the influence of comorbid psychopathology on empathy in EDs.

Alexithymia predicts maladaptive but not adaptive emotion regulation strategies in adolescent girls with anorexia nervosa or depression

BACKGROUND

Among adolescent girls, anorexia nervosa (AN) and major depression (MD) are common and often comorbid mental health problems. Both disorders are characterised by difficulties in recognising and verbalising (alexithymia) as well as regulating one's emotions, but research in adolescent patients is scarce and little is known about the relation between alexithymia and difficulties in emotion regulation. The aims of this study were to investigate alexithymia and emotion regulation skills in adolescents with AN, adolescents with MD, and healthy adolescents, and to determine whether alexithymia functions as a predictor for emotion regulation skills.

METHODS

Emotion regulation strategies, alexithymia, and depressive symptoms were assessed by questionnaire measures in 12-18 year old girls with AN (n = 26), girls with MD (n = 25), and healthy girls (n = 35). Groups were compared with respect to the these variables and multiple regression analyses were calculated separately for adaptive and maladaptive emotion regulation strategies in order to examine if alexithymia predicted emotion regulation over and above age and depressive symptoms.

RESULTS

Girls with AN or MD both reported using adaptive emotion regulation strategies less frequently and maladaptive emotion regulation skills more frequently as well as higher levels of alexithymia compared to healthy girls. Alexithymia positively predicted maladaptive emotion regulation strategies, while depressive symptoms negatively predicted adaptive emotion regulation strategies.

CONCLUSIONS

The results suggest that different mechanisms may underlie the lack of adaptive and the surplus of maladaptive emotion regulation strategies in adolescent psychiatric patients.

The impact of attachment distress on affect-centered mentalization: An experimental study in psychosomatic patients and healthy adults

Introduction

We investigated the impact of attachment distress on affect-centered mentalization in a clinical and a non-clinical sample, comparing mentalization in a baseline condition to mentalization under a condition of attachment distress.

Methods

The sample consisted of 127 adults who underwent inpatient psychosomatic treatment, and 34 mentally healthy adults. Affect-centered mentalization was assessed by analyzing participants’ narratives on interpersonal situations in a baseline condition with the Levels of Emotional Awareness Scale (LEAS), and an experimental condition inducing attachment distress with the Adult Attachment Projective Picture System (AAP). Unlike the LEAS, the AAP is specifically designed to trigger attachment distress. In both conditions, the narratives were evaluated using the LEAS scoring system. Additionally, we assessed the impact of childhood trauma on affect-centered mentalization with the Childhood Trauma Questionnaire (CTQ).

Results

While the non-clinical sample displayed the same level of affect-centered mentalization in both conditions, the majority of the clinical sample reached higher scores in the attachment distress condition. There was no strong relationship between reported trauma and mentalization scores.

Discussion

Our findings lend strong empirical support to the assumption that affect-centered mentalization is modulated by attachment-related distress. Several possible explanations for the differences between and within the clinical and the non-clinical sample are discussed.

The Relationship Between Alexithymia and Emotional Awareness: A Meta-Analytic Review of the Correlation Between TAS-20 and LEAS

Background: Alexithymia and emotional awareness may be considered overlapping constructs and both have been shown to be related to psychological and emotional well-being. However, it is not clear how the constructs relate to each other empirically or if they may overlap more or less in different populations. The aim of this review was therefore to conduct a meta-analysis of correlations between the most commonly used measures of alexithymia (i.e., the self-report instrument Toronto Alexithymia Scale; TAS-20) and emotional awareness (i.e., the observer-rated instrument Level of Emotional Awareness Scale; LEAS) and to explore potential moderators of their relationship.

Methods: Electronic databases were searched for studies published until the end of February 2018. Study samples were coded as medical conditions, psychiatric disorders and/or healthy controls and sample mean age and gender distribution were extracted. Correlations between the TAS-20 and the LEAS were subjected to a random effect of meta-analysis and moderators were explored in subgroup analyses and meta-regressions. Publication bias was considered.

Results: 21 studies reporting on 28 independent samples on correlation analysis were included, encompassing a total of 2857 subjects (57% women). The aggregated correlation between TAS-20 and LEAS was r = −0.122 (95% CI [−0.180, −0.064]; Z = −4.092; p < 0.001), indicating a significant, but weak, negative relationship between the measures. Heterogeneity was moderate, but we found no indication of significant differences between patients with medical conditions, psychiatric disorders or healthy controls, nor that mean age or percentage of female subjects moderated the relationship. The overall estimate became somewhat weaker after adjusting for possible publication bias.

Conclusions: Our results indicate that TAS-20 and LEAS measure different aspects of emotional functioning. The small overlap suggests that alexithymia and emotional awareness are distinct constructs of emotional well-being. Clinicians need to assess both aspects when considering treatment options for individual patients. Moreover, from the clinical standpoint, an easy reliable and valid way of measuring emotional awareness is still needed. More research should be focus on the differences between alexithymia and emotional awareness in specific conditions, but also how to integrate self-report instrument and observed based measures in a clinical situation.

Alexithymia, not fibromyalgia, predicts the attribution of pain to anger-related facial expressions

BACKGROUND

Fibromyalgia (FM) is a syndrome characterized by chronic, widespread musculoskeletal pain, occurring predominantly in women. Previous studies have shown that patients with FM display a pattern of selective processing or cognitive bias which fosters the encoding of pain-related information. The present study tested the hypothesis of an increased attribution of pain to facial expressions of emotions (FEE), in patients with FM. As previous studies have shown that alexithymia influences the processing of facial expressions, independent of specific clinical conditions, we also investigated whether alexithymia, rather than FM per se, influenced attribution of pain to FEE.

METHODS

One hundred and twenty-three women (41 with FM, 82 healthy controls, HC) were enrolled in this cross-sectional case-control study. We adopted two pain-attribution tasks, the Emotional Pain Estimation and the Emotional Pain Ascription, both using a modified version of the Ekman 60 Faces Test. Psychological distress was assessed using the Hospital Anxiety and Depression Scale, and alexithymia was assessed using the Toronto Alexithymia Scale.

RESULTS

Patients with FM did not report increased attribution of pain to FEE. Alexithymic individuals demonstrated no specific problem in the recognition of basic emotions, but attributed significantly more pain to angry facial expression.

LIMITATIONS

Our study involved a relatively small sample size. The use of self-reported instruments might have led to underestimation of the presence of frank alexithymia in individuals having borderline cut-off scores.

CONCLUSIONS

Alexithymia, rather than FM per se, plays a key role in explaining the observed differences in pain attribution to anger-related facial expressions.

Processing and regulation of negative emotions in anorexia nervosa: An fMRI study

Theoretical models and recent advances in the treatment of anorexia nervosa (AN) have increasingly focused on the role of alterations in the processing and regulation of emotions. To date, however, our understanding of these changes is still limited and reports of emotional dysregulation in AN have been based largely on self-report data, and there is a relative lack of objective experimental evidence or neurobiological data. The current functional magnetic resonance imaging (fMRI) study investigated the hemodynamic correlates of passive viewing and voluntary downregulation of negative emotions by means of the reappraisal strategy detachment in AN patients. Detachment is regarded as adaptive regulation strategy associated with a reduction in emotion-related amygdala activity and increased recruitment of prefrontal brain regions associated with cognitive control processes. Emotion regulation efficacy was assessed via behavioral arousal ratings and fMRI activation elicited by an established experimental paradigm including negative images. Participants were instructed to either simply view emotional pictures or detach themselves from feelings triggered by the stimuli. The sample consisted of 36 predominantly adolescent female AN patients and a pairwise age-matched healthy control group. Behavioral and neuroimaging data analyses indicated a reduction of arousal and amygdala activity during the regulation condition for both patients and controls. However, compared with controls, individuals with AN showed increased activation in the amygdala as well as in the right dorsolateral prefrontal cortex (dlPFC) during the passive viewing of aversive compared with neutral pictures. These results extend previous findings indicative of altered processing of salient emotional stimuli in AN, but do not point to a general deficit in the voluntary regulation of negative emotions. Increased dlPFC activation in AN during passive viewing of negative stimuli is in line with the hypothesis that the disorder may be characterized by excessive self-control. Taken together, the data seem to suggest that reappraisal via detachment may be an effective strategy to reduce negative arousal for individuals with AN.

Coping strategies and perceived social support in fibromyalgia syndrome: Relationship with alexithymia

Fibromyalgia (FM) is a chronic pain syndrome characterized by high levels of psychological distress and alexithymia, a personality disposition affecting emotional self-awareness. The main aim of the present study was to investigate for the first time the relationship between alexithymia and coping strategies on the one hand, and alexithymia and perceived social support on the other, in a sample of FM patients. To reach this aim, 153 FM patients completed a battery of tests assessing coping strategies, perceived social support, alexithymia, psychological distress and pain intensity. Four regression analyses were performed to assess whether alexithymia was still a significant predictor of coping strategies and perceived social support, after controlling for psychological distress. High levels of both psychological distress and alexithymia were found in our sample of FM patients. Regarding coping strategies, FM patients reported higher scores on problem-focused coping, with respect to the other two coping strategies. The regression analyses showed that the externally-oriented thinking factor of alexithymia significantly explained both problem- and emotion-focused coping, while the difficulty-describing feelings factor of alexithymia proved to be a significant predictor of perceived social support. Only the variance of dysfunctional coping ceased to be uniquely explained by alexithymia (difficulty identifying feelings factor), after controlling for psychological distress, particularly anxiety. These results highlight a negative relationship between alexithymia and both the use of effective coping strategies and the levels of perceived social support in FM patients. An adequate assessment of both alexithymia and psychological distress should therefore be included in clinical practice with these patients.

Low oxytocin levels are related to alexithymia in anorexia nervosa

OBJECTIVE

Anorexia nervosa is associated with social-emotional functioning deficits and low levels of the social neurohormone oxytocin, even after weight gain. The relationship between low oxytocin levels and social-emotional functioning impairment has not been studied.

METHOD

We performed a cross-sectional study of 79 women (19 who were less than 85% of ideal body weight [IBW] with anorexia nervosa [AN], 26 who were 90-120% IBW with a history of AN [AN-WR], and 34 who were 90-120% IBW with no eating disorder history [H]). We administered the Eating Disorder Examination-Questionnaire (EDE-Q), Leibowitz Social Anxiety Scale-Self Report (LSAS-SR), Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ; suspiciousness and insecure attachment subscales), and the Toronto Alexithymia Scale (TAS-20). We also analyzed fasting serum oxytocin levels.

RESULTS

Most measures of social-emotional functioning showed impairment in women with AN and AN-WR compared to H. Oxytocin levels were low in AN-WR compared to H. Across groups, low oxytocin levels were associated with difficulty identifying feelings (r = -.45, p = .008) and overall alexithymia (r = -.34, p = .0489).

DISCUSSION

We speculate that low oxytocin levels may contribute to alexithymia in women with anorexia nervosa.

Momentary emotion identification in female adolescents with and without anorexia nervosa

Individuals with anorexia nervosa (AN) often report difficulties in identifying emotions, which have been mostly studied as an alexithymia trait. In a controlled two-day ecological momentary assessment, we studied the influence of time of day and aversive tension on self-reported momentary emotion identification. Analysis on an aggregated level revealed a significant lower mean emotion identification in the AN group. In a mixed model analysis, the AN group showed lower emotion identification than the control group (HC). Both a general and a group effect of time of day were found, indicating that emotion identification improved during the day in HC, whereas a negligible decrease of the emotion identification over time was observed in the AN group. Age was associated positively with emotion identification in general, but no specific effect on a group level was found. No effect of aversive tension was found. Our results indicate that an improvement during the day might be a natural process of emotion identification, which is hindered in AN. Future research should focus on temporal relations between emotion identification and disordered eating behavior to further evaluate the clinical relevance of emotion identification difficulties in AN.

Alexithymia in eating disorders: Systematic review and meta-analyses of studies using the Toronto Alexithymia Scale

OBJECTIVE

The aim of this review was to synthesise the literature on the use of the Toronto Alexithymia Scale (TAS) in eating disorder populations and Healthy Controls (HCs) and to compare TAS scores in these groups.

METHOD

Electronic databases were searched systematically for studies using the TAS and meta-analyses were performed to statistically compare scores on the TAS between individuals with eating disorders and HCs.

RESULTS

Forty-eight studies using the TAS with both a clinical eating disorder group and HCs were identified. Of these, 44 were included in the meta-analyses, separated into: Anorexia Nervosa; Anorexia Nervosa, Restricting subtype; Anorexia Nervosa, Binge-Purge subtype, Bulimia Nervosa and Binge Eating Disorder. For all groups, there were significant differences with medium or large effect sizes between the clinical group and HCs, with the clinical group scoring significantly higher on the TAS, indicating greater difficulty with identifying and labelling emotions.

CONCLUSION

Across the spectrum of eating disorders, individuals report having difficulties recognising or describing their emotions. Given the self-report design of the TAS, research to develop and evaluate treatments and clinician-administered assessments of alexithymia is warranted.

A Meta-analysis on the Association Between Emotional Awareness and Borderline Personality Pathology

Theories on borderline personality pathology (BPP) suggest that characteristic emotional dysregulation is due to low levels of emotional awareness or alexithymia. This study is the first meta-analysis to systematically review and analyze the evidence. A systematic search of the literature was performed using PsycInfo, Web of Science/MEDLINE, and Scopus. The term "borderline personality disorder" was searched for in conjunction with "emotional awareness," "emotional self-awareness," "emotion recognition," "alexithymia," "emotional processing," "emotional granularity," "emotional intelligence," or "emotion regulation." All references in the included studies were reviewed for additional relevant articles. Thirty-nine studies were then evaluated in a random effects meta-analysis to assess the association between BPP and emotional awareness. An overall moderate positive association between BPP and emotional awareness was significant (r = 0.359; 95% CI [0.283, 0.431]; Z = 8.678; p < 0.001) along with high heterogeneity (Q(38) = 456.7; p < .001; I² = 91.7%). Studies comparing borderline personality disorder to healthy controls yielded a strong association (r = 0.518; 95% CI [0.411, 0.611]). No significant difference was found between studies using instruments for emotional awareness and those using alexithymia instruments. The strongest associations with regard to aspects of alexithymia were found for difficulties in identifying and describing emotions rather than externally oriented thinking. The results corroborate a moderate relationship between low emotional awareness and BPP. However, the mono-method self-report used in almost all studies is found problematic and precludes drawing definite conclusions. Since leading psychotherapeutic treatments strongly focus on increasing emotional awareness, future research should address this issue and further examine to what extent low levels of emotional awareness, particularly alexithymia, can be treated.

Pain experience in Fibromyalgia Syndrome: The role of alexithymia and psychological distress

BACKGROUND

Fibromyalgia (FM) is a chronic pain syndrome with a high prevalence of alexithymia, a personality disposition that affects emotional self-awareness. The present study aimed to investigate the relationship between alexithymia and pain, differentiating between the sensory and affective components of pain experience, in a sample of FM patients.

METHODS

One hundred and fifty-nine FM patients completed a battery of tests assessing pain experience, pain intensity, alexithymia and psychological distress. In order to characterize the clinical profile of alexithymic FM patients, alexithymic and non-alexithymic groups were compared on the different measures. Two regression analyses were performed on the total sample, in order to investigate the relationship between alexithymia and pain, controlling for psychological distress.

RESULTS

Alexithymic FM patients presented higher scores on all the clinical measures compared to non-alexithymic ones. Positive correlations were found between alexithymia and the affective, but not the sensory, dimension of pain experience variables. Regression analyses showed that alexithymia (difficulty identifying feelings factor) ceased to uniquely predict affective pain, after controlling for psychological distress, particularly anxiety. In addition, none of the alexithymia variables significantly explained pain intensity variance. Finally, a significant effect of anxiety in mediating the relationship between alexithymia and affective pain was found.

LIMITATIONS

No longitudinal data were included.

CONCLUSIONS

These findings show the presence of higher levels of pain and psychological distress in alexithymic vs. non-alexithymic FM patients, and a relevant association between alexithymia and the affective dimension of pain experience. Specifically, this relationship appears to be significantly mediated by anxiety.

Differences in alexithymia and emotional awareness in exhaustion syndrome and chronic fatigue syndrome

Symptoms of Exhaustion Syndrome (ES) and Chronic Fatigue Syndrome (CFS) are overlapping and create difficulties of differential diagnosis. Empirical studies comparing ES and CFS are scarce. This study aims to investigate if there are any emotional differences between ES and CFS. This cross-sectional study compared self-reported alexithymia and observer-rated emotional awareness in patients with ES (n = 31), CFS (n = 38) and healthy controls (HC) (n = 30). Self-reported alexithymia was measured with the Toronto Alexithymia Scale-20 (TAS-20) and emotional awareness with an observer-rated performance test, the Level of Emotional Awareness Scale (LEAS). Additionally, depression and anxiety were scored by the Hospital Anxiety and Depression Scale (HADS). Results show that patients with ES expressed higher self-reported alexithymia in the TAS-20 compared to HC, but had similar emotional awareness capacity in the observer-rated performance test, the LEAS. Patients with CFS expressed more difficulties in identifying emotions compared to HCs, and performed significantly worse in the LEAS-total and spent more time completing the LEAS as compared to HC. Correlation and multiple regressions analyses revealed that depression and anxiety positively correlated with and explained part of the variances in alexithymia scores, while age and group explained the major part of the variance in LEAS. Findings of this study indicate that emotional status is different in patients with ES and CFS with respect to both self-reported alexithymia and observer-rated emotional awareness. Emotional parameters should be approached both in clinical investigation and psychotherapy for patients with ES and CFS.

Alexithymia, empathy, emotion identification and social inference in anorexia nervosa: A case-control study

Alexithymia, difficulties in facial emotion recognition, poor socio-relational skills are typical of anorexia nervosa (AN). We assessed patients with AN and healthy controls (HCs) with mixed stimuli: questionnaires (Toronto Alexithymia Scale-TAS, Interpersonal Reactivity Index-IRI), photographs (Facial Emotion Identification Test-FEIT) and dynamic images (The Awareness of Social Inference Test-TASIT). TAS and IRI Personal Distress (PD) were higher in AN than HCs. Few or no differences emerged at the FEIT and TASIT, respectively. Larger effect sizes were found for the TAS results. Despite higher levels of alexithymia, patients with AN seem to properly acknowledge others' emotions while being inhibited in the expression of their own.

Brain correlates of alexithymia in eating disorders: A voxel-based morphometry study

AIMS

Alexithymia is a personality trait that consists of difficulty in identifying and acknowledging one's own and others' feelings. Recent studies reported that alexithymia is present in both anorexia (AN) and bulimia nervosa (BN). Brain morphological studies on healthy subjects showed that alexithymia correlates with several brain regions involved in emotions processing. The aim of this study was to investigate the anatomical correlates of alexithymia in AN and BN.

METHODS

We performed a voxel-based morphometry study on 21 patients with AN and 18 with BN. Seventeen healthy subjects were used as a control group. Alexithymia, depression and anxiety were assessed with self-administered questionnaires and correlated to gray matter (GM) density in each group.

RESULTS

In BN, alexithymia was correlated with the GM of the parietal lobe, in particular of the right angular gyrus. The correlation was predominantly linked with Difficulty Describing Feelings. In AN, we did not find correlations between GM and alexithymia.

CONCLUSIONS

In BN, our results support the hypothesis that this trait may represent a relevant pathogenic or maintenance factor that contributes to relational difficulties, present in this pathology. In AN, the lack of correlation between GM volume and alexithymia may be influenced by atrophy in several brain regions that in turn can be, as previously reported, a consequence of caloric restriction. Also, the nature of alexithymia may be different from that of BN and controls and this trait could be secondary to a psychopathologic process specific to AN.

Dimensions of emotion dysregulation in anorexia nervosa and bulimia nervosa: A conceptual review of the empirical literature

Several existing conceptual models and psychological interventions address or emphasize the role of emotion dysregulation in eating disorders. The current article uses Gratz and Roemer's (2004) multidimensional model of emotion regulation and dysregulation as a clinically relevant framework to review the extant literature on emotion dysregulation in anorexia nervosa (AN) and bulimia nervosa (BN). Specifically, the dimensions reviewed include: (1) the flexible use of adaptive and situationally appropriate strategies to modulate the duration and/or intensity of emotional responses, (2) the ability to successfully inhibit impulsive behavior and maintain goal-directed behavior in the context of emotional distress, (3) awareness, clarity, and acceptance of emotional states, and (4) the willingness to experience emotional distress in the pursuit of meaningful activities. The current review suggests that both AN and BN are characterized by broad emotion regulation deficits, with difficulties in emotion regulation across the four dimensions found to characterize both AN and BN, although a small number of more specific difficulties may distinguish the two disorders. The review concludes with a discussion of the clinical implications of the findings, as well as a summary of limitations of the existing empirical literature and suggestions for future research.

Emotion generation and regulation in anorexia nervosa: a systematic review and meta-analysis of self-report data

This systematic review sought to examine the generation and regulation of emotion in people with Anorexia Nervosa (AN). Key databases (Medline, Embase, PsychINFO and Web of Science) were searched for peer-reviewed articles published by March 2015 yielding 131 studies relevant to emotion generation and emotion regulation (ER) processes as defined by Gross (1998). Meta-analyses determined pooled group differences between AN and healthy control (HC) groups. More maladaptive schemata were reported by people with AN than HCs, with largest pooled effects for defectiveness/shame (d=2.81), subjugation (d=1.59) and social isolation (d=1.66). Poorer awareness of and clarity over emotion generated and some elevated emotionality (disgust and shame) were reported. A greater use of 'maladaptive' ER strategies was reported by people with AN than HCs, alongside less use of 'adaptive' strategies. Pooled differences of particularly large effect were observed for: experiential avoidance (d=1.00), negative problem-solving style (d=1.06), external/social comparison (d=1.25), submissiveness (d=1.16), attention concentration (worry/rumination; d=1.44) and emotion suppression (d=1.15), particularly to avoid conflict (d=1.54). These data support the notion that emotion regulation difficulties are a factor in AN and support use of associated cognitive-affective models. The implications of these findings for further understanding AN, and developing models and related psychological interventions are discussed.

Alexithymia, a compounding factor for eating and social avoidance symptoms in anorexia nervosa

Socio-affective difficulties, in particular difficulties in representing, communicating and feeling emotions, may play a critical role in anorexia nervosa (AN). The aim of this longitudinal study was to explore the links between alexithymia and two types of difficulties in AN: eating symptoms and social avoidance. Sixty adolescent girls with AN were recruited following hospitalisation in a specialised department. They completed self-administered questionnaires of alexithymia (TAS-20), of central symptoms of the eating disorders (EDI), and of anxious and depressive affects (SCL-90). Anxiety and social avoidance were assessed in the course of a standardised interview (LSAS). These measures were performed at inclusion, and at 6-, 12- and 18-months' follow-up. The relationship between TAS-20 and EDI or LSAS total scale scores across the four time points was assessed using mixed-effects models, including anxiety, depression, BMI, anorexia subtype, and age as co-factors. Partial least square regression was used to refine this multivariate analysis at subscale level, at inclusion and 18 months. Robust associations between TAS-20 and EDI scores were found, independently from anxious and depressive scores, nutritional state and AN subtype. These effects appeared more particularly linked to the implication of the dimensions difficulties identifying and describing feelings, interpersonal mistrust, feelings of inadequacy and interoceptive awareness deficit. There was also a durable association between alexithymia and social anxiety and avoidance, after adjusting for the confounding effects of depression, and anxiety, and the state of starvation. Difficulties in describing feelings appeared particularly involved here. Thus alexithymia does appear as a factor in the persistence of disorders in AN, and difficulties identifying and describing feelings could compound the social difficulties and major the relational isolation of these patients.

Emotion recognition deficits in eating disorders are explained by co-occurring alexithymia

Previous research has yielded inconsistent findings regarding the ability of individuals with eating disorders (EDs) to recognize facial emotion, making the clinical features of this population hard to determine. This study tested the hypothesis that where observed, emotion recognition deficits exhibited by patients with EDs are due to alexithymia, a co-occurring condition also associated with emotion recognition difficulties. Ability to recognize facial emotion was investigated in a sample of individuals with EDs and varying degrees of co-occurring alexithymia, and an alexithymia-matched control group. Alexithymia, but not ED symptomology, was predictive of individuals' emotion recognition ability, inferred from tolerance to high-frequency visual noise. This relationship was specific to emotion recognition, as neither alexithymia nor ED symptomology was associated with ability to recognize facial identity. These findings suggest that emotion recognition difficulties exhibited by patients with ED are attributable to alexithymia, and may not be a feature of EDs per se.

Alexithymia in eating disorders: therapeutic implications

A high percentage of individuals affected by eating disorders (ED) achieve incomplete recovery following treatment. In an attempt to improve treatment outcome, it is crucial that predictors of outcome are identified, and personalized care approaches established in line with new treatment targets, thus facilitating patient access to evidence-based treatments. Among the psychological factors proposed as predictors of outcome in ED, alexithymia is of outstanding interest. The objective of this paper is to undertake a systematic review of the literature relating to alexithymia, specifically in terms of the implications for treatment of ED. In particular, issues concerning the role of alexithymia as a predictor of outcome and as a factor to be taken into account in the choice of treatment will be addressed. The effect of treatments on alexithymia will also be considered. A search of all relevant literature published in English using PubMed, PsycINFO, and Scopus databases was carried out on the basis of the following keywords: alexithymia, anorexia nervosa, bulimia nervosa, eating disorders, and treatment; no time limits were imposed. Despite the clinical relevance of alexithymia, the number of studies published on the above cited aspects is somewhat limited, and these studies are largely heterogeneous and feature significant methodological weaknesses. Overall, data currently available mostly correlate higher levels of alexithymia with a less favorable outcome in ED. Accordingly, alexithymia is seen as a relevant treatment target with the aim of achieving recovery of these patients. Treatments focusing on improving alexithymic traits, and specifically those targeting emotions, seem to show greater efficacy, although alexithymia levels often remain high even after specific treatment. Further investigations are needed to overcome the methodological limitations of previous studies, to understand the actual impact of alexithymia on ED outcome, and to allow more precise implications for treatment to be drawn. Additional research should also be undertaken to specify which of the alexithymic dimensions are specifically relevant to the course and outcome of ED, and to identify treatment protocols producing a significantly greater efficacy in ED patients with relevant alexithymic traits.

Empathy and social functioning in anorexia nervosa before and after recovery

INTRODUCTION

People with anorexia nervosa (AN) are known to have difficulties with social and emotional functioning, as indicated by their symptom presentation and also performance on tests of emotion perception. This study explores the level of empathy in AN, in terms of resonant experience of emotion in other people using a self-report measure.

METHODS

Twenty-eight women with acute AN were compared to 25 women who have recovered from AN, and a further 54 healthy control (HC) participants. They were assessed using a questionnaire to measure reported levels of empathy, emotional recognition, social conformity, and antisocial behaviour.

RESULTS

The acute AN group reported lower levels of empathy than the recovered AN group and HC, but they also reported less antisocial behaviour. No differences were found in emotional recognition or social conformity.

CONCLUSIONS

These results suggest that emotional empathy is reduced during acute AN. Lower levels of antisocial behaviour may reflect a contrasting desire of people with AN to minimise presentation of antisocial behaviour in the acute state.
