Cognitive distortions in anorexia nervosa and borderline personality disorder

Mapping the Path to Cognitive Balance: Applying the States of Mind Model and Network Analysis to Eating Disorder Patients

Background: In eating disorders (EDs), cognitive-behavioral therapy (CBT) represents one of the first-line treatment options albeit with sub-optimal results. The assessment of cognitive balance through an index measuring increased adaptive thinking and reduced maladaptive thinking, the desired outcomes, and the ultimate goal of CBT treatments warrants attention. The states of mind model (SOM) provides a framework through which a cognitive balance index can be defined. The current cross-sectional controlled study tested the clinical utility of the SOM model in a sample of ED outpatients. Methods: ED outpatients (n = 199) were assessed at baseline with the attitudes and beliefs scale-2 (ABS-2) for rational beliefs (RBs) and irrational beliefs (IBs), from which a SOM ratio score index (RBs/(RBs + IBs)) was calculated, the eating disorder inventory-3 (EDI-3) for ED symptoms and ED-related psychopathological features, the psychological well-being scales (PWB) for positive psychological functioning. A matched control sample (n = 95) was also assessed with the ABS-2. Results: ED patients exhibited significantly lower SOM and RB scores compared to controls. Network analysis results highlighted the centrality of the SOM-cognitive balance index, PWB-self-acceptance, and EDI-3-general psychological maladjustment, as well as the importance of the influence that cognitive balance and general psychological maladjustment exert on each other. Conclusions: The findings support the clinical utility of the SOM ratio applied to cognitions in EDs. This demonstrates its ability to differentiate such patients from controls and in capturing worse ED-related general psychopathology as well as compromised aspects of psychological well-being, in particular self-acceptance and environmental mastery. It thus might be considered in CBT treatment of EDs a potential cognitive clinimetric and clinical index of ED severity indicating key difficulties in counteracting maladaptive thinking with adaptive thinking.

The mind-in-mind study: A pilot randomised controlled trial that compared modified mentalisation based treatment with supportive clinical management for patients with eating disorders without borderline personality disorder

OBJECTIVE

Mentalisation-based treatment (MBT) aims to improve reflective functioning. There is a growing evidence base outlining positive clinical outcomes for the use of MBT in eating disorder patients with co-morbid borderline personality disorder (BPD). The use of MBT has not been studied for eating disorder patients without BPD. This pilot study is an exploratory randomised controlled trial in which outcomes from MBT are compared with standard clinical management in a cohort of patients diagnosed with an eating disorder but not BPD. The main objectives were two-fold-to explore the use of MBT as a therapeutic modality and to test the acceptability and feasibility of the protocol design.

METHOD

Thirty-two participants were randomised to receive either MBT or standard treatment during an inpatient eating disorders program. All patients enrolled in the study were diagnosed with an eating disorder but did not meet DSM-5 criteria for BPD. On admission patients were categorised as very underweight (BMI 15.0-16.4 kg/m² ), underweight (BMI 16.5-18.4 kg/m² ) or healthy weight range (BMI ≥ 18.5-24.9 kg/m² ). Upon discharge participants were further categorised as weight restored (BMI ≥ 18.5 kg/m² ) or non-weight restored (BMI < 18.5 kg/m² ). The primary outcome was the subscale score on the Reflective Functioning Questionnaire (RFQ-8). Secondary outcomes were subscale scores on the Eating Disorder Examination Questionnaire and the Depression, Anxiety and Stress Scale (DASS)-21. Participants were assessed at baseline and on discharge. Statistical significance was determined using repeated measurements analysis of variance (ANOVA).

RESULTS

Both groups experienced improvements in eating disorder symptoms and measures of psychological well-being. Participants within the MBT group exhibited greater improvements in reflective capacity as defined by the RFQ-8 however these benefits appeared to be limited to patients who achieved weight restoration at discharge. The eligibility criteria-which excluded comorbid BPD-led to challenges in recruitment which limited the power of the study analysis. As participants with a range of different eating disorder diagnoses were included this led to complexities in estimating the treatment effect within a defined cohort.

CONCLUSIONS

Although the small sample size must be noted as a limitation-the finding that weight restoration appears to be associated with improvements in reflective capacity in MBT would be worth exploring in a subsequent larger study. Modification of eligibility criteria and recruitment from a defined cohort may increase the efficiency of a future study.

Links between cognitive distortions and cognitive emotion regulation strategies in non-clinical young adulthood

This study examined the possible link between cognitive distortions (CDs), which involve erroneous information processing in normal reasoning, and cognitive emotion regulation strategies (CERS), which are strategies implemented at the cognitive level to modulate the emotional response following a negative or unpleasant event, in a non-clinical young adult population. Ninety-six participants (age 18-39 years; 48 women) completed the French version of the Cognitive Emotion Regulation Questionnaire and the French Cognitive Distortions Inventory for adults. Overall, negative distortions were positively correlated with the use of non-adaptive strategies of cognitive emotion regulation, while positive distortions were negatively correlated with the use of adaptive strategies. The CDs most associated with the use of adaptive CERS were positive dichotomous reasoning, minimization and neutral omission in favour of the positive. Selective abstraction was the CD most associated with the use of non-adaptive CERS. We observed a negative correlation effect between education level and several distortions and catastrophizing, and a positive correlation with acceptance. Men used more positive maximization, requalification as negative, acceptance and blaming others than women. The discussion of the results focuses on explaining the observed relationships between the variables in this non-clinical sample.

Irrational Beliefs and Their Role in Specific and Non-Specific Eating Disorder Symptomatology and Cognitive Reappraisal in Eating Disorders

BACKGROUND

Research on which specific maladaptive cognitions characterize eating disorders (ED) is lacking. This study explores irrational beliefs (IBs) in ED patients and controls and the association between IBs and ED-specific and non-specific ED symptomatology and cognitive reappraisal.

METHODS

79 ED outpatients with anorexia nervosa, bulimia nervosa, or other specified feeding or eating disorders and 95 controls completed the Attitudes and Beliefs Scale-2 (ABS-2) for IBs. ED outpatients also completed the Eating Disorder Inventory-3 (EDI-3) for ED-specific (EDI-3-ED Risk) and non-specific (EDI-3-General Psychological Maladjustment) symptomatology; General Health Questionnaire (GHQ) for general psychopathology; Emotion Regulation Questionnaire (ERQ) for cognitive reappraisal.

RESULTS

Multivariate analysis of variance with post hoc comparisons showed that ED outpatients exhibit greater ABS-2-Awfulizing, ABS-2-Negative Global Evaluations, and ABS-2-Low Frustration Tolerance than controls. No differences emerged between ED diagnoses. According to stepwise linear regression analyses, body mass index (BMI) and ABS-2-Awfulizing predicted greater EDI-3-ED Risk, while ABS-2-Negative Global Evaluations and GHQ predicted greater EDI-3-General Psychological Maladjustment and lower ERQ-Cognitive Reappraisal.

CONCLUSION

Awfulizing and negative global evaluation contribute to better explaining ED-specific and non-specific ED symptoms and cognitive reappraisal. Therefore, including them, together with BMI and general psychopathology, when assessing ED patients and planning cognitive-behavioral treatment is warranted.

Evaluating schema modes and cognitive distortions in borderline personality disorder: A mixed-method approach

OBJECTIVES

Cognitive processes, such as schema modes and cognitive distortions, may play a role in the genesis and maintenance of affective, interpersonal, and behavioral difficulties in individuals with Borderline Personality Disorder (BPD). This study aimed at exploring the schema modes and cognitive distortions in individuals with BPD.

METHODS

Using a mixed-method approach, 30 individuals with BPD and 30 healthy participants were assessed on the Borderline Personality Questionnaire, the Schema Mode Inventory, the Cognitive Distortions Scale, and a semi-structured interview schedule.

RESULTS

The BPD group had higher scores than the control group on all the maladaptive schema modes and cognitive distortions subscales. The child modes were the commonest and were also the strongest correlate of BPD symptomatology. Qualitative analysis of the content of the semi-structured interview also corroborated these findings.

CONCLUSIONS

There could be many schema modes and cognitive distortions operating behind the diverse psychopathology seen in BPD.

Cognitive and emotional regulation in adolescents and young women with eating disorders

BACKGROUND

Eating disorders (EDs) are associated with a reduced ability to regulate emotion and impulses during the life span. Working memory and executive functions (EFs) are cognitive regulatory systems supported by networks involving the pre-frontal cortex. Studies in EDs found impaired functioning in these domains, showing an association between EDs and the reduced ability to control emotions and impulses.

OBJECTIVE

To investigate EF in adolescents and young women with eating disorders (ED) using a quasi-experimental design, focusing on cognitive efficiency, emotional regulation (ER) and behavioural outcomes also taking into account pharmacological treatment and duration of illness.

METHODS

A sample of 151 females belonging to two groups took part in this study. Twenty-six girls and young women (M_age 22;8 years) with ED and 125 typically developed girls and young women (M_age 17;4 years) completed a battery of cognitive tasks (Go-no-go, Stop-signal task, Symmetry span, Reading Span) and the Youth Self-Report and the Difficulties in Emotional Regulation Scale Performance. A series of ANOVA with the Brown-Forsythe test was used to compare the groups.

RESULTS

Participants with ED and controls did not show significant differences in EF tasks, whereas differences between younger and older participants with ED emerged. Moreover, ER difficulties seem to be associated with mainly internalizing problems in EDs. Further analysis on the full ED sample did not reveal any significant differences associated with the disorder persistence. Considering pharmacological treatment effects over cognitive, emotional and behavioural measures emerged.

CONCLUSIONS

The present study documented no specific differences in EF between control and participants with EDs, whereas important differences emerged in ER and behavioural outcomes perception in the clinical sample, together with a partial influence of pharmacological treatment.

LEVEL OF EVIDENCE

No level of evidence.

Common and distinct brain functional alterations in pharmacotherapy treatment-naïve female borderline personality disorder patients with and without auditory verbal hallucinations: a pilot study

Auditory verbal hallucinations (AVHs) are experienced by approximately 25% of patients with borderline personality disorder (BPD). Despite the high incidence, the pathological features of AVH in BPD remain unclear. This study aimed to investigate whole-brain functional connectivity (FC), as measured by functional connectivity density (FCD), and its relationship with AVH in BPD. 65 pharmacotherapy treatment-naïve female BPD patients (30 with AVH and 35 without AVH), and 35 female healthy controls were investigated. Functional magnetic resonance imaging (fMRI) data were collected to assess whole-brain FC and functional connectivity density mapping (FCDM) was applied to the fMRI data to compute FCD features. Compared to the healthy controls, both BPD groups (BPD-AVH and BPD without AVH) exhibited significantly higher gFCD values in the bilateral prefrontal lobe, bilateral orbital lobule, and bilateral insula, and significantly lower gFCD values in the SMA, right anterior temporal lobule, and the ACC. These altered regions were significantly associated with AVH in the BPD subjects. Moreover, higher gFCD values were observed in the left posterior temporal lobule and posterior frontal lobule. Aberrant alterations also emerged in the left posterior temporal lobule and posterior frontal lobule, mainly in Broca and Wernicke regions. Nevertheless, there was no significant correlation between gFCD values and the severity of AVH as measured by the AVH scores. In summary, we have identified aberrations in the FC and brain metabolism of the aforementioned neural circuits/networks, which may provide new insights into BPD-AVH and facilitate the development of therapeutic approaches for treating AVH in BPD patients.

Do metacognitions mediate the relationship between irrational beliefs, eating disorder symptoms and cognitive reappraisal?

Objective: Cognitively oriented therapies, first-line treatment for eating disorders (EDs), still show room for improvement in treatment retention and outcomes. Despite the development of additional cognitive models and therapies, few studies examine the relationship between traditional and third-wave cognitive targets in EDs. The study explores the relationship between irrational beliefs (IBs) and metacognitions and their relationship with ED psychopathology and cognitive reappraisal in ED outpatients. Method: Seventy-seven patients (mean age 27.49 ± 12.28 years) were assessed with The Attitudes and Beliefs Scale-ABS-2, Meta-cognitions Questionnaire-MCQ-65, Eating Disorder Inventory 3-EDI-3, Eating Attitudes Test-EAT-40, Emotion Regulation Questionnaire-ERQ. Results: Correlational analyses showed that IBs and metacognitions significantly correlated with each other. Metacognitions partially mediated the relationship between IBs and ED-related general psychological maladjustment and completely mediated the relationship between IBs and ED symptom severity. Cognitive reappraisal was predicted only by IBs and metacognitions were not significant mediators. Conclusions: While IBs are sufficient in explaining ED-related psychopathology and reduced use of cognitive reappraisal, a potential integration of metacognitions about need to control thoughts in CBT models for EDs may offer incremental validity given their contribution to ED severity. Treatment implications include targeting metacognitions concerning need to control thoughts, as a potential maintenance mechanism of ED symptomatology through cognitive restructuring.
