A model of self-criticism as a transdiagnostic mechanism of eating disorder comorbidity: A review

A network approach to personality vulnerability symptom structure across early, middle, and late adolescence: Insights from a large-scale sample

BACKGROUND

The two-polarity model of personality development posits that personality vulnerabilities, specifically dependency and self-criticism, play a critical role in adolescent psychopathology risk. This theoretical framework emphasizes the importance of understanding how these vulnerabilities manifest and develop during adolescence, as adolescents face distinct developmental challenges at different stages. However, existing research overlooks the impact of stage-specific challenges on the development of personality vulnerabilities.

METHOD

This study included 24,946 Chinese adolescents (Mage ± SD = 15.50 ± 2.03; 46.50 % girls) divided into three age groups: early (10-13 years, N = 4652), middle (14-17 years, N = 15,065), and late (18-20 years, N = 5229). We employed network analysis to investigate the symptom structure of self-criticism and dependency through different adolescent stages, focusing on core symptoms (highly connected nodes), bridges (links between dependency and self-criticism), and potential causal relationships.

RESULT

Feelings of disappointing others and loneliness after arguments are consistently central to self-criticism and dependency, respectively. Connections between these vulnerabilities change across stages. Evidence from the directed acyclic graph suggests that self-criticism gradually replaces dependency as the key to triggering experiences of personality vulnerability from early to late adolescence.

CONCLUSION

This study identified the personality vulnerability network structure across three stages of adolescents. The results highlight a developmental shift in the triggering sequences of personality vulnerability, moving from predominantly dependency in early adolescence to increased self-criticism in later stages. These insights underscore the significance of the developmental context in shaping personality vulnerabilities across adolescence and offer crucial directions for stage-specific interventions.

eBEfree: Combining Psychoeducation, Mindfulness, and Self-Compassion in an App-Based Psychological Intervention to Manage Binge-Eating Symptoms: A Randomized Controlled Trial

OBJECTIVE

To develop and test the effectiveness of the eBEfree program, a 12-session app-based version of a previously tested psychological intervention (BEfree) that combines psycho-education, self-compassion, mindfulness, and Acceptance and Commitment Therapy to reduce binge-eating symptoms.

METHOD

Two-hundred participants with recurrent elevated binge-eating symptoms and a higher body weight were enrolled in a remote parallel-group randomized trial, of which 142 completed the initial assessment (70 in the intervention group). The end-of-treatment and follow-up assessments were conducted 12 weeks after the initial assessment and 26 weeks after the end of treatment, respectively. Intention-to-treat (ITT) analyzes were undertaken using frequentist linear mixed models and Bayesian hierarchical models to test the intervention effectiveness.

RESULTS

43 (waitlist control) and 29 (intervention) participants completed the end-of-treatment assessment, showing a high attrition rate (51%). ITT analyzes showed the eBEfree program to be associated with a significant reduction in binge eating symptomatology from baseline to end-of-treatment (β = -9.49, ρ < 0.0001, g = -1.17), and from end-of-treatment to 26-weeks follow-up (β = -6.01, ρ = 0.04, g = -1.08). At end-of-treatment, the intervention was also associated with a decrease in body mass index and depression symptomatology, as well as an improvement in dimensions of self-criticism and mindfulness. More than 80% of participants rated the quality of the program as positive and helpful.

DISCUSSION

This trial suggests potential benefits of the eBEfree program to help individuals manage symptoms of binge-eating more effectively, reduce weight, and improve well-being and mental health. The intervention benefits should be confirmed in future larger trials.

PUBLIC SIGNIFICANCE

Treating binge-eating (BE) symptoms and associated comorbidities might be challenging for mental health services. Digital and app-based interventions can be a valuable resource to help people manage symptoms and improve well-being and mental health. The current trial suggests the potential benefits of an app-based intervention (eBEfree program) to help people reduce BE symptoms and develop psychological strategies to promote well-being and mental health.

I Don't Deserve Anything Good: Perfectionistic Self-Recrimination in a Case of Comorbid Personality and Eating Disorder

In this case study we present the course of the psychotherapy of Myriam, a 19-year old female with a severe personality disorder and comorbid eating disorder. During the initial assessment she reported high levels of neuroticism that parallel the diagnosis of obsessive-compulsive personality disorder, borderline personality disorder, and anorexia nervosa. Myriam showed a severely impaired personality functioning defined by perfectionism, self-criticism, interpersonal guilt and overcontrol. Her daily experience was shaped by a self-recriminative inner dialogue associated with maladaptive patterns in the form of food, water and sleep restrictions, self-harm behaviors, and suicidal ideation. She accessed an integrative treatment based on individual (Evolutionary Systems Therapy) and group psychotherapy (Mindful Compassion for Perfectionism). At the end of 14-month intervention she remitted from all the categorical diagnoses and showed reliable changes in several measures. These outcomes were maintained at 3-month follow-up. We describe the integrative conceptualization based on Myriam's perfectionistic self-recrimination patterns, and the consequent treatment that targeted these patterns rather than focusing on symptom reduction exclusively.

Understanding the transdiagnostic mechanisms underlying emerging psychopathology in adolescence: study protocol of a 1-year prospective epidemiological (EMERGE) study

INTRODUCTION

Adolescent mental health is a global public health challenge as most cases remain undetected and untreated, and consequently, have a high likelihood of persistence or recurrence. It is critical to improve early detection of mental disorders and to target individuals experiencing subclinical symptoms. However, most indicated prevention approaches have been developed for risk syndromes of specific mental disorders. This contradicts the increasing recognition of emerging psychopathology as a complex system characterised by rapid shifts in subclinical symptoms, cutting across diagnostic categories and interacting with each other over time. Therefore, this study aims to examine the dynamic course, pattern and network of subclinical symptoms and transdiagnostic mechanisms over time.

METHOD AND ANALYSIS

The EMERGE-study is a prospective, naturalistic, 1-year follow-up study. A general population sample of 1196 adolescents will be recruited. Inclusion criteria are age between 11 and 17 years, German language skills, main residency in Switzerland and access to internet. Individuals will be excluded if they have a current or lifetime axis I mental disorder. Assessments of subclinical symptoms of several mental disorders and potential transdiagnostic mechanisms will be conducted at baseline and at 3-month, 6-month, 9-month and 12-month follow-up. Structural equation modelling will be used to estimate the homotypic and heterotypic patterns of subclinical symptoms and the associations with transdiagnostic mechanisms. Latent growth mixture modelling and growth mixture survival analysis will be carried out to identify subclasses of individuals with different trajectories of subclinical symptoms that may be predictive of an onset of a mental disorder. Network analysis will be applied to assess the centrality of subclinical symptoms and how networks of emerging psychopathology change over time.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Bern Cantonal Ethics Committee (ID 2020-02108). All findings will be disseminated by publication in peer-reviewed scientific journals and by presentation of the results to conferences and stakeholder organisation events.

Efficacy of a transdiagnostic Internet prevention approach in adolescents (EMPATIA study): study protocol of a randomized controlled trial

BACKGROUND

Most mental disorders have their onset in adolescence. Preventive interventions during this period are important; however, help-seeking behavior is generally poor in this age group resulting in low treatment rates. Internet interventions are expected to be an effective, low-threshold, and scalable approach to overcome barriers to help-seeking, particularly for individuals experiencing subclinical symptoms. Internet-delivered indicated prevention seems promising as it targets individuals with minimal symptoms of mental disorders who might need care but are not help-seeking yet. Previous indicated prevention-approaches have mainly targeted specific risk-syndromes. However, this contradicts the increasing recognition of emerging psychopathology as a complex system characterized by co-occurrence and rapid shifts of subclinical symptoms cutting across diagnostic categories. Therefore, this study will investigate the efficacy, mediators, moderators, and core symptomatic changes of a transdiagnostic Internet-delivered indicated prevention program (EMPATIA program) for adolescents.

METHODS

This randomized controlled trial (RCT) will be conducted in a general population sample (planned n = 152) of adolescents aged 12-18 years with subclinical symptoms but without any current or past mental disorder. Participants will be randomly assigned to the EMPATIA program or a care as usual (CAU) control condition. The 8-week guided EMPATIA program encompasses 8 modules targeting the following transdiagnostic mechanisms: repetitive negative thinking, self-perfectionism, emotion regulation, intolerance of uncertainty, rejection sensitivity, and behavioral avoidance. Participants will be asked to answer online self-report questionnaires at baseline, after 8 weeks, and at 6-, 9-, and 12-month follow-up. Diagnostic telephone interviews will be conducted at baseline and at 12-month follow-up. Additionally, intervention-specific constructs (motivation, alliance, negative effects, satisfaction, adherence) will be assessed during and after the EMPATIA program. The level of self-reported general psychopathology post-intervention is the primary outcome.

DISCUSSION

Results will be discussed considering the potential of Internet interventions as a scalable, low-threshold option for indicated prevention in adolescents experiencing subclinical symptoms. The EMPATIA program introduces a novel Internet prevention program targeting six transdiagnostic mechanisms associated with various mental health outcomes. Thereby, this trial pursues a very timely and important topic because it may contribute to narrow the current care gap for adolescents, to prevent mental health problems and related negative consequences, and to promote mental health in the long-term.

TRIAL REGISTRATION

The trial was approved by Swissmedic (Registration Number: 10001035, 08/22/2022) and the Ethics Committee of Bern (Registration Number: 2022-D0036, 08/22/2022). The trial was registered at ClinicalTrials.gov NCT05934019 on 07-03-2023.

"I'm so dumb and worthless right now": factors associated with heightened momentary self-criticism in daily life

Self-criticism is a trait associated with increased psychopathology, but self-criticism is also a personality state reflecting an action that people do in moments of time. In the current study, we explored factors associated with heightened self-criticism in daily life. Participants (N = 197) received five random prompts per day for one week on their mobile phones, where they reported their current affect (negative and positive affect), willpower self-efficacy, distress intolerance, degree of support and criticism from others, current context (location, activity, hunger, tiredness) and momentary self-criticism. We first demonstrated that self-criticism varies over time and across contexts, and is associated with heightened trait self-criticism. Then, using multilevel modelling, we explored the contextual factors associated with greater self-criticism. We found that self-criticism was higher when people were at home, and more tired. We also found higher self-criticism to be associated with greater negative and lower positive affect, greater distress intolerance, lower willpower and greater perceived criticism from others. In addition, self-criticism predicted subsequent distress intolerance, willpower and positive affect in lagged analyses. This study provides evidence that both environmental and psychological factors are associated with the dynamics of self-critical thoughts.

Testing for longitudinal bidirectional associations between self-compassion, self-criticism, and positive body image components

Previous cross-sectional studies have reported associations between self-compassion, self-criticism, and positive body image, yet prospective studies establishing the temporal order of these relationships are missing. The present study sought to clarify the nature of these associations by investigating possible longitudinal bi-directional links between self-compassion, self-criticism, and three components of positive body image (body appreciation, functionality appreciation, and body image flexibility). Data were analyzed from 2982 adult women who completed survey instruments at baseline (T0), four-month follow-up (T1), and eight-month follow-up (T2). Attrition rate ranged from 0-56% across time-points. Cross-lagged panel models were computed to test for bidirectional associations. We found evidence of reciprocal, negative associations between self-criticism and the three components of positive body image across the three time-points. We also found evidence that T0 self-compassion predicted increased body image flexibility and functionality appreciation at T1 (paths were non-significant from T1 to T2), whereas T0 body appreciation predicted increased T1 self-compassion (but was non-significant from T1 to T2). Findings suggest that compassionate and uncritical ways of responding to the self may be relevant precursors and outcomes to positive body image, depending on the timing of assessment, highlighting viable targets for intervention.

A meta-analysis of disordered eating and its association with self-criticism and self-compassion

OBJECTIVE

Future treatments for eating disorders (ED) need to be enhanced by targeting maintaining mechanisms. Literature suggests self-criticism and self-critical perfectionism act as key mechanisms exacerbating ED, and self-compassion protects against self-criticism. This meta-analysis examines associations between self-criticism and self-critical perfectionism on disordered eating (DE), and reviews how self-compassion and self-criticism relate to each other with respect to DE.

METHOD

Searches across three databases yielded 135 studies across 42,952 participants. Heterogeneity, publication bias, and quality assessments were analyzed. Moderation analyses between self-criticism measures, self-compassion measures, between clinical and nonclinical samples, and between cross-sectional and experimental studies were also conducted.

RESULTS

Random-effects models showed a medium positive link between self-criticism and DE (r = .37), and 10 subgroups pertaining to various measures of self-criticism utilized in literature showed small to large positive links with DE (r = .20-.52). Preliminary evidence also suggests negative relationships between self-compassion and DE (r = -.40 to -.43) and negative relationships between self-compassion and self-criticism (r = -.04 to -.88).

DISCUSSION

Greater levels of self-criticism is linked with greater levels of DE and reduced levels of self-compassion, suggesting a need to tackle self-criticism and nurture self-compassion in standard treatments for ED. Understanding these interactions better in conjunction with dismantling intervention studies can help develop more effective and efficient interventions targeting self-criticism and self-compassion for people with DE.

PUBLIC SIGNIFICANCE STATEMENT

Higher levels of self-criticism are linked with higher levels of DE and lower self-compassion. Self-compassion interventions could be more effective and efficient in reducing ED symptoms if self-criticism is tackled early in such treatments.

Eating disorders among queer and trans individuals: Implications for conceptualization, assessment, and treatment

Eating disorders (EDs) have been traditionally viewed as a disorder affecting cisgender, heterosexual women. Yet, the prevalence of EDs among queer and trans (QnT) individuals, coupled with the lack of interventions that attend to contextual factors related to sexual orientation and gender identity, underscore a critical health disparity issue requiring urgent attention. Here, we first review factors pertaining to QnT individuals' minoritized sexual and gender identities that are important to consider in ED conceptualization for this population (e.g., minority stressors, identity-based body image standards). Next, we describe problematic assumptions present in existing ED assessment and propose more inclusive approaches. Lastly, we provide suggestions for practices that providers can implement within their treatment of EDs among QnT individuals.

Targeting the link between social media and eating disorder risk: A randomized controlled pilot study

OBJECTIVE

Evaluate the feasibility, acceptability, and preliminary efficacy of a self-criticism intervention addressing the link between appearance-motivated social media use and eating disorder risk. Another condition, designed to help users curate their social media feed to reduce negative impacts on wellbeing, was also trialed as an active and credible comparison.

METHOD

University students aged 17-25 (N = 170) were screened and randomized (n = 130) to the self-criticism intervention, social media curation, or waitlist control group. The intervention comprised self-guided cognitive behavior therapy delivered in four modules over 1 week. Primary outcomes were feasibility and acceptability. Secondary outcomes were appearance motivations for social media use, appearance comparison, self-criticism, body image flexibility, and disordered eating (at baseline, one-week postrandomization, and two-weeks postrandomization).

TRIAL REGISTRATION

ACTRN12621000353897.

RESULTS

Participants completed an average of 82% of the intervention modules and 77% of the homework exercises within the week allocated. The intervention was well-accepted; participants reported a range of positive aspects, alongside suggested modifications to the intervention and study design to improve acceptability. Group by time interactions suggested groups changed at a different rate on three secondary outcomes; between-groups effect sizes suggested this was due to greater improvements in the self-criticism group than waitlist control.

DISCUSSION

This was the first study to evaluate an intervention for the link between appearance-related social media use and eating disorder risk for young adults. Positive findings relating to feasibility, acceptability, and preliminary efficacy suggest a larger randomized controlled trial, with modifications to the intervention and study design, is warranted.

PUBLIC SIGNIFICANCE

Appearance-related social media use has been linked to poorer body image and disordered eating, necessitating treatments that can disrupt this relationship. The self-criticism intervention evaluated in this study shows promise as a strategy to address this need. It is the first intervention focused on appearance-related social media use to be designed for and tested in young adults, who are at heightened risk of developing an eating disorder.
