The Role of Emotion Regulation in Eating Disorders: A Network Meta-Analysis Approach

Highest correlations between emotion regulation strategies and mood symptoms in bipolar disorder: A systematic review and Bayesian network meta-analysis

Bipolar disorder (BD) is associated with alterations in emotion regulation (ER) strategies, with both depressive and (hypo)manic symptoms correlated with utilization of maladaptive instead of adaptive strategies. However, which ER strategies are the most affected during the most severe mood symptoms remains unclear despite the potentially relevant treatment implications. To this end, we conducted a systematic review and Bayesian network meta-analysis (NMA) of studies documenting correlations between ER and depressive and (hypo)manic symptoms of BD, from inception until November 9th, 2023. We included 15 studies in the review, 14 of which provided data to conduct a Bayesian NMA. Rumination emerged as the ER strategy most strongly associated with both depressive (ES=0.43, 95 %CrI=0.27,0.59) and (hypo)manic symptoms (ES=0.26, 95 %CrI=0.05,0.46) of BD. Other ER strategies showed associations primarily with depressive symptoms. There was no significant heterogeneity or network inconsistency. These findings emphasize the importance of rumination in BD and suggest that altered ER strategies are more evident in depressive symptoms rather than (hypo)manic ones. While promising for targeted interventions, these results are based on cross-sectional data, limiting causal interpretation. Future longitudinal studies are necessary to clarify the temporal dynamics of the relationship between affective symptoms and ER in BD.

Efficacy of the Eat Breathe Thrive Recovery Protocol Delivered Virtually to Adults Recovering From Eating Disorders: A Randomized Controlled Trial

OBJECTIVE

Current treatments for eating disorders have limited effectiveness, leaving over half of patients unremitted. The evaluation of emerging interventions to support recovery is therefore critical. This study evaluated the efficacy and acceptability of an innovative, virtual intervention for eating disorders (Eat Breathe Thrive; EBT-R).

METHOD

Participants recovering from eating disorders from 27 different countries (N = 277) were randomly allocated to EBT-R or waitlist conditions. Assessments were completed at baseline, postintervention, and three-month follow-up. Primary outcomes were eating disorders and co-occurring psychopathology; secondary outcomes included measures of positive embodiment.

RESULTS

Compared with controls, participants in EBT-R demonstrated significant improvements in eating disorders and associated psychopathology (i.e., depression, anxiety) than controls. Participants also reported increased appreciation for the body, interoception, interoceptive attunement, intuitive eating, emotion regulation, mindful self-care, and integrity.

DISCUSSION

This study evaluated the efficacy of a brief, virtual, embodiment-focused intervention for eating disorders. The findings suggest that EBT-R may be an effective intervention to support recovery from eating disorders and development of positive embodiment.

Validation of the Difficulties in Emotion Regulation Scale-Short Form in a sample of Italian adolescents

OBJECTIVE

The primary objective of the present study is to validate the Difficulty in Emotion Regulation Scale-Short Form (DERS-SF) in a sample of Italian adolescents. Additionally, we aim to evaluate its factorial structure by examining the contribution of each subscale (i.e., Nonacceptance, Clarity, Awareness, Goals, Impulse, Strategy) on the general factor using bi-factor models by replicating a past study.

METHOD

The sample comprises N = 704 adolescents aged 11-17 years (M = 13.38, SD = 1.37; 53.12% females). To establish external validity, correlation and path analyses were conducted between the DERS-SF sub-scales, the total score, and measures of internalizing and externalizing symptoms, as well as Problematic Smartphone Use (PSU). Measurement invariance was tested comparing males versus females and pre-adolescents and adolescents.

RESULTS

Overall, results supported the multidimensional nature of the DERS-SF, confirming its original six-factor structure. However, bi-factor models analysis revealed that the Awareness subscale should be excluded when calculating the total score. Furthermore, findings indicated that the Strategy subscale variance is largely accounted for by the general factor rather than the specific subscale. In terms of external validity, significant positive associations between the DERS-SF sub-scales, the total score, and PSU, internalizing and externalizing symptoms were observed. Measurement invariance was supported.

CONCLUSIONS

Altogether, findings support the validity of the DERS-SF among Italian Adolescents and provide insights relevant to the understanding of the multifaceted facets of emotion regulation, emphasizing its relevance as a transdiagnostic process.

Social cognition and bulimic symptoms in male undergraduate students: The conditional effect of emotion dysregulation

OBJECTIVE

Research demonstrates associations between poor social cognition and eating disorder (ED) pathology. Moreover, research shows that individuals with EDs struggle with emotion regulation. The present study replicates and extends the literature on social cognition and ED pathology, which previously focused largely on symptoms of anorexia nervosa among women while the present study focuses on symptoms of bulimia nervosa among undergraduate men. Further, this study tests the hypothesis that better emotion regulation mitigates the association between social cognition and ED pathology.

METHODS

At a single timepoint, undergraduate males (n = 520) completed a series of questionnaires, and a task assessing mentalising, a key element of social cognition.

RESULTS

Consistent with hypotheses, bulimic symptoms were associated with worse mentalising and worse self-reported emotion regulation. Moreover, the association between mentalising and bulimic symptomatology was conditional on emotion regulation, such that it was strongest among those with more difficulties regulating their emotions.

CONCLUSION

Results are consistent with existing theories that highlight an interplay between interpersonal (e.g., mentalisation) and intrapersonal (e.g., affective functioning) factors in relation to ED symptomatology. Among undergraduate males, bulimic symptoms were associated with worse mentalisation. However, a good ability to regulate emotions interrupted this association.

Eating Behaviors Associated With Suicidal Behaviors and Overall Risk

OBJECTIVE

Maladaptive eating behaviors remain prevalent in the US population, and a significant percentage of US college students acknowledge engaging in maladaptive eating. Formally defined eating disorders (EDs) have one of the highest mortality rates among all mental illnesses. Suicide risk is substantially elevated among individuals diagnosed with EDs, and even subclinical levels of maladaptive eating behaviors are associated with suicidality. The current study examined associations between specific problematic eating behaviors measured dimensionally (eg, purging, binging, laxative use) and specific suicide-related constructs and behaviors as well as overall suicide risk.

METHODS

College students (N=188; 62% women) completed the Eating Disorder Examination-Questionnaire, a well-established measure of dysfunctional eating, as well as several self-report measures of theoretical components of suicidality, and, finally, a semistructured clinical interview to specify suicide risk category.

RESULTS

Results showed a general pattern of moderate and strong associations between the subscales and the overall score of the Eating Disorder Examination-Questionnaire and core suicide constructs of the interpersonal-psychological theory of suicide. Many substantive correlations were found between specific eating behaviors and specific suicide-related behaviors; for example, purging was the highest correlate of overall suicide risk (ρ=0.36).

DISCUSSION

These results are discussed in terms of consistency with the interpersonal-psychological theory of suicide as well as practical implications for intervention.

Maternal emotion regulation abilities affect adolescent depressive symptoms by mediating their emotion regulation ability: An ERP study

Adolescents with major depressive disorder (MDD) experience significant difficulties in emotion regulation. This study aimed to explore emotion regulation in adolescents with depression using an emotion regulation paradigm combined with event-related potentials (ERP) while investigating the relationship between maternal emotion regulation and adolescent depressive symptoms through a mediation model. Overall, 38 healthy controls (HC) and 57 adolescents with depression (MDD) rated the pictures they saw according to aversive reappraisal (reappraisal of an aversive picture or down-regulate aversive emotions), aversive watch, and neutral conditions. Adolescents with depression gave more negative ratings to aversive images, and the emotional regulation success index (ERSI) of adolescents with depression was lower than that of healthy individuals. ERP data revealed an elevation in late positive potential (LPP) amplitude during the aversive reappraisal and aversive watch conditions compared with that in the neutral condition in the MDD group. Compared with the HC group, adolescents with depression showed larger LPP amplitudes under aversive watch conditions. The aversive reappraisal condition evoked a larger LPP than that in the other conditions in the HC group in the late time windows. The ΔLPP (separating the variability in the ERP wave associated with emotion regulation) was larger in the HC group than in the MDD group. Mediation analysis revealed that maternal emotion regulation influenced adolescent depression levels through its effect on the adolescent's emotion regulation. These findings provide important insights into the emotion regulation process in adolescents with depression and offer suggestions for clinical interventions.

Early adaptive schemas, emotional regulation, and cognitive flexibility in eating disorders: subtype specific predictors of eating disorder symptoms using hierarchical linear regression

PURPOSE

Understanding how early adaptive schemas, cognitive flexibility, and emotional regulation influence eating disorder (ED) symptoms, and whether this differs across diagnostic subtypes is critical to optimising treatment. The current study investigated the relationship between these variables and ED symptomology in individuals self-reporting an ED diagnosis and healthy controls.

METHODS

A dataset of 1576 online survey responses yielded subsamples for anorexia nervosa (n = 155), bulimia nervosa (n = 55), binge eating disorder (n = 33), other specified feeding or eating disorder (n = 93), and healthy participants (n = 505). The hierarchical linear regression analysis included Eating Disorder Examination Questionnaire 6.0 Global Score as the dependent variable; Young Positive Schema Questionnaire, Emotional Regulation Questionnaire, and Cognitive Flexibility Inventory subscale scores as the independent variables; and demographic measures as the covariates.

RESULTS

The number of significant predictors varied considerably by ED sub-group. Amongst the anorexia nervosa, bulimia nervosa, and healthy subsamples, the adaptive schema Self-Compassion and Realistic Expectations was associated with lower ED symptom severity. In comparison, age and body mass index were the strongest predictors for binge eating disorder, whilst the Expressive Suppression (a subscale of the Emotional Regulation Questionnaire) was the strongest predictor for other specified feeding or eating disorders.

CONCLUSION

Early adaptive schemas, cognitive flexibility, and emotional regulation vary across ED subtype, suggesting the need for tailored treatment that disrupts the self-reinforcing cycle of ED psychopathology. Future research investigating how early adaptive schemas may predict or be associated with treatment response across diagnostic subtypes is needed.

LEVEL OF EVIDENCE

Level IV, evidence obtained from multiple time-series with or without the intervention, such as case studies.

A controlled trial assessing the acceptability and efficacy of a yoga-based eating disorder prevention program among division I athletes: Eat Breathe Thrive (EBT)

OBJECTIVE

This study evaluated the acceptability and effectiveness of the Eat Breathe Thrive (EBT) program as an eating disorder prevention intervention among women collegiate athletes.

METHOD

Change over time in eating disorder risk and competencies of positive embodiment were examined in 94 women (n = 48 EBT participants and n = 46 matched-controls) from one National Collegiate Athletic Association (NCAA) Division I-classified university in the United States. Eating disorder risk factors were measured using the Eating Disorder Examination Questionnaire (EDE-Q) and State Trait Anxiety Inventory (STAI). Aspects of positive embodiment were measured using the Multidimensional Assessment of Interoceptive Awareness (MAIA) and The Mindful Self-Care Scale (MSCS). Data were collected through participants' completion of online surveys across three time-points.

RESULTS

Repeated measures ANOVAS revealed EBT participants reported experiencing significantly less state anxiety and greater interoceptive body trusting over time relative to matched-controls. No other significant interactions were found. Respondents found the EBT program acceptable.

DISCUSSION

Acceptability and partial support for integrative, yoga-based, interventions targeting Division I student-athletes is indicated.

Metacognition as a transdiagnostic factor across eating disorders: a latent profile analysis study

Background

Metacognition is a crucial aspect of understanding and attributing mental states, playing a key role in the psychopathology of eating disorders (EDs). This study aims to explore the diverse clinical profiles of metacognition among patients with EDs using latent profile analysis (LPA).

Method

A total of 395 patients with a DSM-5 diagnosis of ED (116 AN-R, 30 AN/BP, 100 BN, 149 BED) participated in this study. They completed self-report measures assessing metacognition, eating psychopathology, depression, emotional dysregulation, personality traits, and childhood adversities. LPA and Welch ANOVAs were conducted to identify profiles based on metacognition scores and examine psychological differences between them. Logistic regression models were employed to explore associations between personal characteristics and different profiles.

Results

A 3-class solution had a good fit to the data, revealing profiles of high functioning (HF), intermediate functioning (IF), and low functioning (LF) based on levels of metacognitive impairments. Participants in the IF group were older and had a higher BMI than those in the HF and LF groups. Individuals with BN were largely categorized into HF and LF profiles, whereas participants with BED were mainly included in the IF profile. Participants in the LF group reported an impaired psychological profile, with high levels of depression, emotional dysregulation, childhood adversity, and personality dysfunction. Multinomial logistic regression analyses showed significant associations between metacognitive profiles and emotional and neglect abuse, emotion dysregulation, and detachment.

Conclusion

This exploratory study unveils distinct metacognitive profiles in EDs, providing a foundation for future research and targeted interventions. In this light, metacognitive interpersonal therapy could be a valid and effective treatment for EDs, as suggested by the initial promising results for these patients.

Eating disorder symptoms and weight pressure in female rowers: associations between self-concept, psychological well-being and body composition

BACKGROUND

Female rowers may be at risk of eating disorders and high weight pressure.

AIM

The purpose of the study was to investigate the prevalence of disordered eating symptoms and weight-related pressure and the associations with self-concept, psychological well-being, socio-demographic data, experience, performance level and body composition in female fixed-bench rowers.

METHODS

Female rowers (n = 208; age ranged mean ± SD 23.6 ± 6.5 years) completed the SCOFF scale, Weight-Pressures in Sport-Females (WPS-F), Physical Self-Concept Questionnaire and the Ryff scales of psychological well-being and provided information on their experience and level of competition. In a subgroup of 115 athletes, body composition was assessed using bioimpedance.

RESULTS

It was found that 42.3% of the athletes scored ≥ 2 on SCOFF and mean ± SD value of WPS-F score was 3.65 ± 0.82. Stepwise regression analysis revealed that self-concept of strength and pressure from teammates and the uniform were associated with higher ED symptoms, whereas better psychological well-being in terms of autonomy, self-concept of attractiveness, and age were protective factors for ED symptoms. BMI, athletes' physical condition, strength, and experience were associated with more weight-related pressure and better self-concept of attractiveness and physical well-being of autonomy were significantly associated with less pressure. In body composition analysis, higher extra cellular water, self-acceptance, and physical condition were associated with more weight-related pressure in female rowers, being attractiveness and the environmental mastery protective elements.

CONCLUSIONS

The prevalence of ED symptomatology and weight-related pressure are high in female fixed bench rowing. The psychological factors of well-being and self-concept, team environment, body image concerns and body composition analysis should be considered to promote healthy eating behaviours in female rowers.

The Mediating Effect of Coping Strategies and Emotion Regulation in the Relationship between Impulsivity, Metacognition, and Eating Disorders

BACKGROUND

Risk factors for eating disorders are multifaceted and complex, so it is crucial to elucidate the role of executive functions, including impulsivity and metacognition, and coping strategies in the severity of eating behaviors. The study aims were threefold: (1) to analyze gender differences in impulsivity, metacognition, coping strategies, emotion regulation, and eating disorders; (2) to examine the correlation between the study variables; and (3) to test the mediating role of coping and emotion-regulation strategies in the relationship between metacognition, impulsivity, and eating disorders.

METHODS

A total of 1076 participants (Mage = 21.78, SD = 5.10; 77.7% women) completed a set of questionnaires. Two mediation analyses were conducted to test the mediating role of coping strategies, including emotion regulation, in the relationship between executive functions (i.e., impulsivity and metacognition) and eating disorders.

RESULTS

Women displayed higher coping strategies, specifically emotional expression, wishful thinking, and social support, whereas men presented greater social withdrawal. Mediational analyses showed a significant association between impulsivity, metacognition, and eating disorders, whose relationship was partially mediated by coping strategies and mainly by emotion regulation.

CONCLUSION

Interventions based on coping strategies and emotion regulation could be a feasible and effective option to deal with eating disorders among the young population.

Risk and resilience in eating disorders: differentiating pathways among psychosocial predictors

OBJECTIVE

Eating disorders (EDs) represent a rising global health concern. The current study takes a multivariate approach to examine psychological (i.e., perfectionism, anxiety sensitivity [AS], emotion dysregulation) and sociocultural factors (i.e., body dissatisfaction) that may relate to risk and resilience in EDs.

METHODS

Participants were 698 undergraduate students (Mage = 21, SDage = 4.02), mainly female (71%) and Hispanic (61.6%), who participated in an online survey assessing perfectionism, emotion dysregulation, AS, body dissatisfaction, and eating behaviors.

RESULTS

The results from structural equation model analyses revealed differential associations with disordered eating (DE) outcomes. Self-oriented perfectionism and dysmorphic appearance concerns were associated with increased dieting/carb restriction, desire for thinness, and binging tendencies. Specifically, emotional nonacceptance and lack of emotional awareness showed associations with elevated risk for dieting/carb restriction and purging tendencies, respectively. Conversely, lack of emotional clarity showed a protective pathway to these risk behaviors. Anxiety sensitivity cognitive concerns related to higher purging tendencies, while AS social concerns related to lower purging and binging tendencies.

DISCUSSION

Findings highlight the differential pathways of psychosocial risk and resilience for EDs. Subscales of emotional dysregulation and AS showed risk as well as resilience associations with DE outcomes. This information is key for advancing transdiagnostic prevention and intervention to reduce the rising rates of EDs.

Are you how you eat? Aspects of self-awareness in eating disorders

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.

Remote family education and support program for parents of patients with adolescent and early adulthood eating disorders based on interpersonal psychotherapy: study protocol for a pilot randomized controlled trial

BACKGROUND

In cases of adolescent and early adulthood eating disorders, despite the importance of the patients' relationship with their parents, conflict and confusion frequently occur among them. Interpersonal psychotherapy (IPT) is a present-focused psychotherapy that emphasizes the interpersonal context of symptoms. We developed a remote family education and support program exclusively for parents of patients with eating disorders, based on the principle of IPT. The use of IPT is expected to reduce conflicts in the patient-parent relationship. Consequently, parents will be better able to listen to patients, and patients will be better able to express their thoughts and desires. In this study, we describe the protocol for a randomized controlled trial designed to examine the effectiveness of this program in promoting effective communication in their home based on active listening skills of parents of patients with adolescent and early adulthood eating disorders.

METHODS

Participants will be parents of patients aged 12-29 years with adolescent and early adulthood eating disorders. Individually randomized, parallel-group trial design will be employed. Seventy participants will be allocated to one of two treatment conditions: (1) remote family education and support program (four, 150 min weekly group sessions) for parents plus treatment-as-usual for patients (consultation by physicians or no treatment), or (2) waiting for the control condition (parents will wait to start the program for 8 weeks) plus treatment-as-usual for patients. The primary outcome measure will be parents' active listening ability as measured by the Active Listening Attitude Scale at 8 weeks after randomization. Additionally, perception of social support (Social Provision Scale-10 item), loneliness (UCLA Loneliness Scale), mental health status (K6), family function (Family Assessment Device), and parent-evaluated eating disorder symptoms (Anorectic Behavior Observation Scale) will be assessed. Data from the intention-to-treat sample will be analyzed 8 weeks after randomization.

DISCUSSION

This is the first study to evaluate the effectiveness of a family education and support program for parents of patients with adolescent and early adulthood eating disorders based on IPT. If this type of intervention is effective, although indirect, it could be a new support method for this patient population.

Cognitive Flexibility and Emotion Regulation in Eating Disorder Patients with Comorbid Generalized Anxiety and Posttraumatic Stress Symptoms

Research has found that difficulties in emotion regulation negatively impact mental health, whereas cognitive flexibility may promote stress resilience and positive mental health. Little is known about cognitive flexibility and emotion regulation in people with comorbid eating disorder (ED) and anxiety and stress disorders. A transdiagnostic ED population (N = 227 ) at an outpatient ED treatment facility completed several self-report instruments that measured cognitive flexibility, emotion regulation difficulties, posttraumatic stress disorder (PTSD) symptoms, and generalized anxiety disorder (GAD) symptoms upon admission. We investigated cognitive flexibility and emotion regulation differences for those with an ED without comorbidity and those with various combinations of comorbidity. In a one-way between-groups ANOVA, we investigated differences in cognitive flexibility for those with GAD, PTSD, neither, and both comorbidities. We found a statistically significant difference between these groups, with mean cognitive flexibility inventory scores being the lowest in the group with both comorbidities. However, when controlling for emotion regulation, a one-way between-groups ANCOVA indicated no significant differences in cognitive flexibility between comorbidity groups F ( 3 , 222 ) = 1.20 , p = . 31 Partial η 2 = . 02 . Though self-reported cognitive flexibility levels differ among ED patients with and without comorbidities, it appears that these differences are better explained by emotion regulation. Therefore, addressing emotion regulation early in treatment for all individuals with EDs, regardless of comorbidity. Further research is needed to understand the impact of treating emotion regulation on ED treatment engagement, dropout, and effectiveness.

Association Between Maladaptive Eating Behaviors Among Black Women and Vicarious Racial Discrimination Following a High-Profile Event

OBJECTIVE

Evidence suggests that racial discrimination causes stress among non-Hispanic Black women, and some Black women may cope with exposure to vicarious racial discrimination by engaging in maladaptive eating behaviors.

METHODS

We examined eating behaviors among Black women (N = 254) before and after Freddie Gray's death while in police custody. Maladaptive eating behaviors were assessed using the three-factor eating questionnaire. Our independent variables included the following: (1) time period and (2) geographic proximity to the event. Three two-way analysis of covariance tests were conducted to assess potential effects of geographic proximity (close, distant), time period in relation to unrest (before, after unrest), and their interaction on emotional eating, uncontrolled eating, and cognitive restraint controlling for participant age.

RESULTS

There was a statistically significant main effect of proximity to the unrest on emotional eating, F (1, 252) = 5.64, p = .018, and partial η2 = .022 such that women living in close geographic proximity to the unrest reported higher mean levels of emotional eating as compared to those living more distant to the unrest. There was also a borderline statistically significant interaction between geographic proximity and time period on cognitive restraint, F (1, 252) = 3.89, p = .050, and partial η2 = .015.

CONCLUSION

Our study found a relationship between vicarious racial discrimination and maladaptive eating behaviors among Black women. Future work should examine stress related to vicarious racial discrimination and maladaptive eating behaviors longitudinally.

Measuring Motivations to Eat Palatable Foods: Adaptation and Psychometric Properties of the Italian Version of the Palatable Eating Motives Scale (PEMS-IT)

BACKGROUND

Gaining knowledge of the various reasons behind people's consumption of highly processed foods has the potential to enhance obesity prevention initiatives and open avenues to tailor treatment approaches for obesity and binge eating at a more personalized level. This contribution aimed to test the psychometric properties and factor structure of the Palatable Eating Motives Scale (PEMS-IT) in a community sample of Italian adults.

METHODS

A confirmatory factor analysis was performed to test the factor structure of the Italian version of the PEMS (PEMS-IT) on a total of 616 respondents. Furthermore, the reliability and convergent validity analysis of the tool were evaluated.

RESULTS

The analysis confirmed the four-factor structure of PEMS-IT [(YBχ2 (164) = 537.901; p < 0.001, the CFI = 0.918, RMSEA = 0.072; 90%CI [0.065-0.078]; p(RMSEA < 0.05) < 0.001, and SRMR = 0.080] and satisfactory reliability on its subscales (Cronbach's α: 0.745-0.917). Positive correlations were also found with food addiction and binge-eating symptoms, compulsive eating behavior, and uncontrolled and emotional eating.

CONCLUSIONS

The PEMS-IT appears to be an instrument with promising psychometric properties and potential applications in clinical settings. However, it also has some limitations, and future studies could focus on improving the semantic content of the elements to increase the overall utility and precision of the instrument.

Early evaluation of a DBT-informed online intervention for people with eating disorders

OBJECTIVES

Eating disorders (EDs) have a worldwide prevalence of 7.8%, with towering mortality rates and high healthcare costs. The current recommended treatment for EDs principally works by directly targeting ED thoughts and behaviours, but recovery rates are low. A multifaceted link between difficulties with emotions and EDs is now widely established, and newer third-wave therapies that aim to address these underlying emotion difficulties are promising. The current study piloted an online emotion self-help intervention which was co-developed with clinicians and people with lived experienced of EDs. The intervention aimed to specifically address difficulties with emotion identification and regulation, as well as unhelpful beliefs about emotions, which are believed to give rise to and maintain ED thoughts and behaviours.

METHOD

We recruited 39 people with self-reported EDs to test this intervention over a one-week period. Our participants were asked to complete a series of questionnaires measuring emotion processes and psychopathology on Day 1 (T1) before being given access to the intervention. Participants were then asked to practice the newly acquired skills for seven days, before taking the same questionnaires on Day 9 (T2). We also asked participants to qualitatively report on their experience of the intervention.

RESULTS

We found significant improvements in ED psychopathology (ED-15), depression (PHQ-9), and anxiety (GAD-7) pre- to post-intervention, with medium to large effect sizes. All our emotion variables namely alexithymia (TAS-20), difficulties regulating emotions (DERS-SF), and unhelpful beliefs about emotions (EBQ) also showed significant changes post-intervention with medium to large effect sizes. Most importantly, changes in emotion regulation processes were linked to improved eating psychopathology. The qualitative analysis corroborated this finding, highlighting how the intervention helped them form new beliefs about emotions, which helped them reduce ED behaviours.

DISCUSSION

Significant improvements in emotion processing and regulations, as well as psychopathology, along with positive qualitative feedback, suggest that the intervention effectively met its aims of increasing awareness of the link between emotions and eating psychopathology, providing help to identify and regulate emotions, and normalising emotional experiences. While our results are promising, further research is required to assess its effectiveness longer term and in clinical settings.

Effects of the COVID-19 pandemic on youth mental health: a cross-sectional study on eating disorder patients and their unaffected siblings

BACKGROUND

Adolescence has emerged as a particularly vulnerable phase during the COVID-19 pandemic, with eating disorders (EDs) representing a prominent psychopathological challenge linked to the restrictions imposed by the pandemic. Emerging evidence suggests that not only individuals with EDs but also their healthy siblings (HS) may experience unique psychological effects in this context. However, the existing literature on this topic remains limited. This study seeks to examine and compare the effects of the pandemic on adolescents and adults, with a specific focus on the impact of containment measures, disruptions in daily routines, and alterations in life trajectories, for both individuals with EDs and their HS.

METHODS

We enrolled 273 individuals, including those diagnosed with EDs and their HS. Among the participants, 120 were under the age of 19. Multiple self-report questionnaires were administered to assess the psychological impact of 1 year of the COVID-19 pandemic. These assessments covered a range of psychological constructs, including posttraumatic symptoms, general psychopathology, and eating-related concerns.

RESULTS

Notably, adolescent patients with EDs demonstrated the highest psychopathological scores within our sample. They were the sole subgroup to surpass clinical cutoffs, exhibiting more pronounced issues concerning eating-related concerns and general psychological well-being. Our findings also shed light on the unique experiences of HS during the pandemic.

CONCLUSION

Our findings highlight the specific psychological burden endured by adolescents with EDs throughout the COVID-19 pandemic, emphasizing the vulnerability of this demographic. Moreover, the experiences of HS, often overlooked in the literature, warrant increased attention in future health programs and interventions.

Correlation between emotion dysregulation and mood symptoms of bipolar disorder: A systematic review and meta-analysis

BACKGROUND

Emotion dysregulation (ED) is a transdiagnostic construct characterized by difficulties regulating intense emotions. People with bipolar disorder (BD) are more likely to show ED and use maladaptive emotion regulation strategies than adaptive ones. However, little is known about whether ED in BD is a trait or it is rather an epiphenomenon of mood symptoms.

METHODS

We conducted a systematic review and meta-analysis of the evidence across major literature databases reporting correlations between measures of emotion regulation (overall ED and different emotion regulation strategies) and measures of depressive and (hypo)manic symptoms in BD from inception until April 12th, 2022.

RESULTS

Fourteen studies involving 1371 individuals with BD were included in the qualitative synthesis, of which 11 reported quantitative information and were included in the meta-analysis. ED and maladaptive strategies were significantly higher during periods with more severe mood symptoms, especially depressive ones, while adaptive strategies were lower.

CONCLUSION

ED significantly correlates with BD symptomatology, and it mainly occurs during mood alterations. ED may be a target for specific psychotherapeutic and pharmacological treatments, according to precision psychiatry. However, further studies are needed, including patients with mood episodes and longitudinal design, to provide more robust evidence and explore the causal direction of the associations.

Childhood maltreatment, alexithymia and eating disorder psychopathology: A mediation model

BACKGROUND

The relationship between childhood maltreatment and eating disorder psychopathology has been under-investigated.

OBJECTIVE

The purpose of this study was to investigate the role of alexithymia in mediating the relationship between childhood maltreatment experiences and eating disorder (ED) symptoms.

PARTICIPANTS AND SETTING

One-hundred-forty-three women with anorexia nervosa, 110 women with bulimia nervosa and 108 healthy women filled in the Eating Disorder Inventory-2, the Childhood Trauma Questionnaire and the Toronto Alexithymia Scale-20 (TAS-20).

METHODS

A mediator path model including childhood trauma types as predictors, the subscales of the TAS-20 as mediators and ED specific symptoms as dependent variables was conducted in individuals with EDs and in healthy women.

RESULTS

In women with EDs emotional abuse was directly associated with body dissatisfaction and was associated to drive to thinness, bulimia and body dissatisfaction through the mediation of difficulties to identify emotions. In healthy women, physical neglect was directly associated to drive to thinness and bulimia, but no significant mediation effect through alexithymia emerged.

CONCLUSION

Impaired emotion recognition mediates the association between childhood emotional abuse and ED symptoms. Individuals with early emotional abuse may experience ED symptoms to manage confused emotional perceptions. Improving emotional understanding and acceptance may be a treatment target in early maltreated individuals with EDs.

Reconceptualizing emotion regulation and coping strategy usage in eating disorders research: The utility of a regulatory flexibility framework

Emotion regulation and coping strategies are often conceptualized in eating disorder (ED) research as inherently adaptive or maladaptive, and successful regulation is often defined as greater overall use of adaptive strategies. However, recent empirical work outside of the field of EDs challenges this categorical conceptualization of strategies, demonstrating that adaptiveness is determined by the ability to flexibly implement and adjust strategies based on contextual demands (i.e., regulatory flexibility). Despite evidence that emotion regulation and coping strategies are best conceptualized in terms of flexibility in the broader literature, few ED studies have adopted this model. We review the current conceptual framework of emotion regulation and coping strategies used in ED research and present regulatory flexibility as an alternative approach to conceptualizing these strategies. The lack of research on regulatory flexibility among individuals with EDs limits our understanding of the role of emotion regulation and coping difficulties in ED risk and maintenance. Adopting a regulatory flexibility model of strategies in EDs may extend knowledge of the role of emotion regulation difficulties in the development and maintenance of EDs. We highlight the potential utility of investigating regulatory flexibility and present recommendations for future research on regulatory flexibility in EDs. PUBLIC SIGNIFICANCE STATEMENT: Research on emotion regulation and coping strategy usage in eating disorders often view regulatory strategies as inherently adaptive or maladaptive. However, recent studies support defining strategies in terms of flexibility. Adopting a regulatory flexibility model of strategies in eating disorders research may advance knowledge of the role of emotion regulation difficulties in the development and maintenance of eating disorders, ultimately enhancing prevention and treatment efforts.

Antidepressant emergent mood switch in major depressive disorder: onset, clinical correlates and impact on suicidality

Antidepressant (AD)- emergent mood switch (AEMS) is a common complication of bipolar depression. This study aimed to investigate the prevalence and clinical correlates of subthreshold AEMS (i.e. not fulfilling DSM criteria for hypomanic episodes) in major depressive disorder (MDD) and, prognostically, its impact on AD treatment outcome and suicidality. The study involved 425 outpatients with MDD followed during the acute phase (12 weeks) and continuation (weeks 13-28) AD treatment. AEMS was assessed through the Altman Self-Rating Mania scale (ASRM ≥ 6). Several clinical features differentiated individuals with or without subthreshold AEMS (n = 204 vs. 221): negative self-perception [odds ratio (OR) 1.017-1.565]; panic disorder (OR 1.000-1.091); subthreshold hypomanic episodes (OR 1.466-13.352); childhood emotional abuse (OR 1.053-2.447); lifetime suicidal behaviour (OR 1.027-1.236); AD-related remission (χ 2  = 22.903 P  < 0.0001) and suicide ideation (χ 2  = 16.701 P  < 0.0001). In AEMS earlier onset showed a strong correlation with bipolar spectrum disorder (overall score: P  = 0.0053; mixed depression: P  = 0.0154; subthreshold hypomania: P  = 0.0150) whereas late-onset was associated with more severe suicidal behaviour ( P  < 0.001). In conclusion, our results demonstrate that subthreshold mood switches occur frequently in unipolar depression during acute AD treatment as well as in continuation phase. Time of switch onset seems to have the greatest diagnostic and prognostic value.

Parental relationships, emotion regulation and orthorexia: A study on adolescent athletes

Background: This study seeks to further our understanding of the factors associated with adolescent athletes and disordered eating, by expanding current research into a less-explored eating disorder known as orthorexia. Aim: The aim of the study is to explore the impact of parents' relationships and emotional regulation on the orthorexia nervosa (ON) tendencies of adolescent athletes. Methods: The participants were 303 adolescents, ranging from 15 to 17 years old, of which 139 participated in competitive sport, and 164 did not. Three self-report questionnaires were administered to assess orthorexia (ORTO-15), relationship with parents (Inventory of Parent and Peer Attachment) and emotion regulation (Emotion Regulation Questionnaire). Results: The results highlight that those who practice sports report higher levels of orthorexia, inadequate relationships with parents, as well as greater emotional regulation difficulties. Furthermore, inadequate parents' relationship predicts orthorexia while expressive emotional regulation mediates this relationship. Conclusion: These findings highlight how ON tendencies in athletes are linked to poor management of emotions combined with inadequate relationships with parents in terms of communication and affection. Implications for practice and support for athletes are discussed.

A prospective study on body image disturbances during pregnancy and postpartum: the role of cognitive reappraisal

Background

During pregnancy, body size rapidly modifies over a relatively short period. Literature emphasizes the need to identify the factors that influence body image during peripartum as the extent of women's adaptation to these changes has significant repercussions on both mother's and newborn's health. Emotion regulation strategies (i.e., expressive suppression and cognitive reappraisal) were linked to body image in the general and clinical population, but no studies were conducted in the peripartum. The present study aims to investigate the longitudinal impact of prepartum body image disturbances on postpartum body image disturbances and to evaluate the mediational role of emotional regulation strategies.

Methods

A total of 133 pregnant women completed a three-phase longitudinal study. Women answered online questionnaires during the second (T1) and the third (T2) trimesters of pregnancy, and at about 6 months postpartum (T3).

Results

Findings indicated that body image disturbances at T1 were a significant predictor of body image disturbances in the postpartum (1 year after the first assessment). Moreover, cognitive reappraisal measured at T2 partially mediated this relationship: body image disturbances in the second trimester of pregnancy were linked to less use of cognitive reappraisal in the third trimester of pregnancy, and this, in turn, was associated with worse body image disturbances at 6 months after birth.

Conclusion

Findings of this longitudinal study highlight the importance of assessing body image disturbances during pregnancy to early identify women at risk, and suggest cognitive reappraisal as a possible target intervention.

Risk of non-fatal self-harm and premature mortality in the three years following hospitalization in adolescents and young adults with an eating disorder: A nationwide population-based study

INTRODUCTION

Eating disorders (ED) are associated with high rates of suicide attempts and premature mortality. However, data in large samples of adolescents and young adults are limited. This study aims to assess the risk of self-harm and premature mortality in young people hospitalized with an ED.

METHODS

Individuals aged 12 to 25 years old hospitalized in 2013-2014 in France with anorexia nervosa and/or bulimia nervosa as a primary or associated diagnosis were identified from French national health records. They were compared to two control groups with no mental disorders, and with any other mental disorder than ED. The main outcomes were any hospitalization for deliberate self-harm and mortality in the 3 years following hospitalization. Logistic regression models were used.

RESULTS

This study included 5, 452 patients hospitalized with an ED, 14,967 controls with no mental disorder, and 14,242 controls with a mental disorder other than an ED. During the three-year follow-up, 13.0% were hospitalized for deliberate self-harm (vs. 0.2 and 22.0%, respectively) and 0.8% died (vs. 0.03 and 0.4%). After adjustment, hospitalization with an ED was associated with more self-harm hospitalizations (hazard ratio [HR] = 46.0, 95% confidence interval [32.3-65.3]) and higher all-cause mortality (HR = 12.6 [4.3-37.3]) relative to youths without any mental disorder; less self-harm hospitalizations (HR = 0.5 [0.5-0.6]) but higher mortality (HR = 1.6 [1.0-2.4]) when compared to youths with any other mental disorder.

CONCLUSION

Young patients hospitalized with an ED are at high risk of self-harm and premature mortality. It is urgent to evaluate and implement the best strategies for post-discharge care and follow-up.

PUBLIC SIGNIFICANCE

We found that the risk of being hospitalized for a suicide attempt is 46 times higher and mortality 13 times higher than the general population in adolescents and young adults during the 3 years following hospitalization with an eating disorder. Eating disorders are also associated with a 1.5 higher risk of premature mortality relative to other mental disorders. This risk is particularly high in the 6 months following hospitalization. It is therefore crucial to implement careful post-discharge follow-up in patients hospitalized for eating disorders.

New Insights and Potential Therapeutic Interventions in Metabolic Diseases

Endocrine homeostasis and metabolic diseases have been the subject of extensive research in recent years. The development of new techniques and insights has led to a deeper understanding of the mechanisms underlying these conditions and opened up new avenues for diagnosis and treatment. In this review, we discussed the rise of metabolic diseases, especially in Western countries, the genetical, psychological, and behavioral basis of metabolic diseases, the role of nutrition and physical activity in the development of metabolic diseases, the role of single-cell transcriptomics, gut microbiota, epigenetics, advanced imaging techniques, and cell-based therapies in metabolic diseases. Finally, practical applications derived from this information are made.

Does trait mindfulness mediate the relationship between borderline personality symptoms and emotion dysregulation?

BACKGROUND

Emotion dysregulation is core to many biopsychosocial models of Borderline Personality Disorder (BPD) and is often targeted as part of their associated psychological therapies. Several distinct specialist psychotherapies are thought to be effective for people diagnosed with BPD but it is unclear whether they share common change mechanisms. Some evidence suggests that Mindfulness Based Interventions improve competency in emotion regulation as well as trait mindfulness, which are both plausibly associated with good treatment outcomes. It is unclear whether the association between the severity of BPD symptoms and emotion dysregulation is mediated by trait mindfulness. Would improvement in trait mindfulness mediate an association between lower severity of BPD symptoms and fewer problems of emotion dysregulation?

METHODS

One thousand and twelve participants completed online, single time-point, self-report questionnaires.

RESULTS

As predicted, the severity of BPD symptoms was significantly and positively associated with emotion dysregulation with a large effect size (r = .77). Trait mindfulness mediated this relationship as the 95% confidence interval for the indirect effect did not cross zero (size of direct effect = .48 and size of indirect effect = .29 [.25, .33].

CONCLUSIONS

The relationship between the severity of BPD symptoms and emotion dysregulation was confirmed in this dataset. As hypothesised, this relationship was mediated by trait mindfulness. Process measures of emotion dysregulation and mindfulness should be included in intervention studies for people diagnosed with BPD to understand if improvements in these factors are a universal occurrence with good response to treatment. Other process measures should also be explored to identify other factors involved in the relationship between BPD symptoms and emotion dysregulation.

Association between social support for mothers of patients with eating disorders and mothers' active listening attitude: a cohort study

BACKGROUND

Family members of patients with eating disorders, especially their mothers, experience heavy caregiving burdens associated with supporting the patient. We predict that increasing caregivers' support will have a positive effect on their active listening attitudes, mental health, loneliness, and self-efficacy. This study aimed to investigate differences in mothers' active listening attitudes, mental health, loneliness, and self-efficacy improvements between mothers who did and did not experience increased perceived social support.

MAIN BODY

Participants were mothers of patients with eating disorders. Questionnaires for this cohort study were sent to the participants' homes at three time points (baseline, 9 months, and 18 months). The Japanese version of the Social Provision Scale (SPS-10) was used to evaluate social support, the Active Listening Attitude Scale (ALAS) for listening attitude, the UCLA Loneliness Scale (ULS) for loneliness, the General Self-Efficacy Scale (GSES) for self-efficacy, the Beck Depression Inventory (BDI-II) for depression symptoms, and the K6 for psychological distress. An unpaired t-test was used to determine whether participants' status differed between the groups that did and did not experience increased perceived social support. The mean age of the participants was 55.1 ± 6.7 (mean ± SD) years. The duration of their children's eating disorders was 7.6 ± 5.5 years. The degree of improvement for each variable (active listening attitude, loneliness, self-efficacy, depressive symptoms, and mental health) was the difference in each score (ALAS, ULS, GSES, BDI-II, and K6) from T1 to T3. The degree of improvement in active listening attitude and loneliness was significantly greater in the improved social support group than in the non-improved social support group (p < 0.002 and p < 0.012, respectively).

CONCLUSIONS

Our findings indicate that increasing mothers' perceptions of social support will be associated with improving their active listening attitudes and loneliness.

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.

Emotion regulation, perfectionism, and eating disorder symptoms in adolescents: the mediating role of cognitive eating patterns

Poor emotion regulation, along with elevated perfectionism, is recognised as a risk factor for the development of eating disorder (ED) symptoms. Therefore, the aim of our study was to examine the relationship between emotion regulation difficulties and perfectionism with ED symptoms, while controlling for emotional eating, uncontrolled eating, and cognitive restraint as mediators. In total, 482 adolescents (246 girls and 236 boys; M = 15.00, SD = 0.31) participated in this study. Based on the participants' body height and weight measured by the medical team during their regular preventive health examinations, the body mass index (BMI) was calculated. Participants also answered the Difficulties in Emotion Regulation Scale, Multidimensional Perfectionism Scale, Three-Factor Eating Questionnaire, and Eating Disorder Examination Questionnaire. According to the results obtained, adolescent girls in our sample reported more difficulties in emotion regulation, more uncontrolled and emotional eating, and more ED symptoms. A significant direct effect was found for difficulties in emotion regulation and ED symptoms but not for perfectionism. In addition, only emotional eating and cognitive restraint (not uncontrolled eating) mediated the relationship between difficulties in emotion regulation and perfectionism and ED symptoms. The results suggest that difficulties in emotion regulation may be more important than perfectionism in explaining ED symptoms in a sample of healthy adolescents. When adolescents experience problems in emotion regulation in combination with emotional or uncontrolled eating, they might be at a higher risk of experiencing concerns about weight and a variety of other ED symptoms, and this should be considered when planning preventive interventions for adolescents.

The mediating role of self-criticism, experiential avoidance and negative urgency on the relationship between ED-related symptoms and difficulties in emotion regulation

OBJECTIVE

Difficulties in emotion regulation are thought to play a transdiagnostic role across eating disorders (ED). In the current study, we explored with a path analysis the mediating role of self-criticism, experiential avoidance and negative urgency on the relationship between ED-related symptoms and dimensions of difficulties in emotion regulation.

METHOD

Participants were 103 female outpatients recruited at a Portuguese ED hospital unit, diagnosed with an ED, aged 14-60 years old (M = 28.0, SD = 10.5), body mass index (BMI) ranging from 11.72 to 39.44 (M = 20.1, SD = 5.4).

RESULTS

The path analysis resulted in a model with an adequate fit to the data (SRMR = 0.05; RMSEA = 0.07 [0.00, 0.12], PCLOSE = 0.269; TLI = 0.97; IFI = 0.99; GFI = 0.95). A final model in which the relationship between ED-related symptoms and dimensions of difficulties in emotion regulation was mediated by self-criticism, experiential avoidance and negative urgency, accounted for a variance of 71% for strategies, 57% for non-acceptance, 62% for impulses, 56% for goals and 20% for clarity.

CONCLUSION

Results suggest that self-criticism, experiential avoidance and negative urgency, combined, are relevant in the relationship between ED-related symptoms and difficulties in emotion regulation. ED treatment and emotion regulation skills may be enhanced through the inclusion of specific components that target self-criticism, experiential avoidance and negative urgency, as they become prominent during the therapeutic process.
