RESUMEN

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.

RESUMEN

OBJECTIVE: The sequential model has been defined as an intensive, two-stage approach that comprises administering two types of treatment consecutively to improve treatment outcomes in cases of non-optimal or absence of treatment response. A psychiatric population that would potentially benefit from the application of the sequential model is the eating disorders (EDs) population. The current scoping review aimed to explore the emerging literature on the application of sequential treatments in EDs. METHOD: Using PRISMA and Population intervention comparison outcomes study guidelines, Pubmed and PsycINFO were systematically searched for studies which applied temporally sequential treatments in patients diagnosed with EDs from inception to April 2022 using a combination of keywords. Studies utilising combined or integrated approaches were excluded. RESULTS: A total of 12 studies were selected and reviewed. Studies included Bulimia Nervosa, Binge Eating Disorder (BED), or mixed ED samples with a majority of female patients. No studies on AN samples were identified. The majority of studies contained a Cognitive-Behavioural Therapy module of treatment, were conducted on BED patients, were in outpatient settings, and included a group format in one or more treatment conditions. Studies varied in number of comparison groups and study design. Secondary and sequentially applied treatment modules were consistent with treatment recommendations of clinical guidelines. CONCLUSIONS: The available data on sequential treatments in EDs is scarce and exhibits methodological limitations that should be addressed in future studies. Definition of sequential treatments in EDs should be further developed to guide robust clinical research and improve empirical support of sequential treatment for complex ED cases and for non-optimal ED treatment response.

RESUMEN

The metacognition of needing to control thoughts has been implicated in eating disorders (EDs)-specifically, in association with the drive for thinness and over-control. To date, it has yet to be investigated longitudinally in ED outpatients undergoing CBT-based treatment. The current study aims to examine whether endorsing a need to control thoughts undergoes modifications during CBT-based treatment for EDs and whether its modification correlates with treatment response in terms of reduced ED symptomatology. Seventy female ED outpatients (34 with AN, 29 with BN, 7 with OSFED) were assessed at baseline and at the end of treatment with the Metacognitions Questionnaire (MCQ), the Eating Attitudes Test (EAT-40), and the General Health Questionnaire (GHQ). Post-treatment, significant reductions were observed in MCQ-need to control thoughts. Using hierarchical linear regression analyses such decreases significantly explained the variance in observed reductions in EAT-oral control and to a lesser extent, reductions in EAT-bulimia and food preoccupation and EAT-dieting. These results underscore the importance of metacognitive change in EDs and the potential utility of CBT-based treatment in its modification. Improving ED outcomes may warrant broadening the therapeutic target of over-control and a sense of loss of control beyond dysfunctional eating behaviors to include maladaptive metacognitions that concern the need to control thoughts.

RESUMEN

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.

RESUMEN

Mental pain (MP) is a transdiagnostic feature characterized by depression, suicidal ideation, emotion dysregulation, and associated with worse levels of distress. The study explores the presence and the discriminating role of MP in EDs in detecting patients with higher depressive and ED-related symptoms. Seventy-one ED patients and 90 matched controls completed a Clinical Assessment Scale for MP (CASMP) and the Mental Pain Questionnaire (MPQ). ED patients also completed the Beck Depression Inventory-II (BDI-II), Clinical Interview for Depression (CID-20), and Eating Attitudes Test (EAT-40). ED patients exhibited significantly greater severity and higher number of cases of MP than controls. Moreover, MP resulted the most important cluster predictor followed by BDI-II, CID-20, and EAT-40 in discriminating between patients with different ED and depression severity in a two-step cluster analysis encompassing 87.3% (n = 62) of the total ED sample. Significant positive associations have been found between MP and bulimic symptoms, cognitive and somatic-affective depressive symptoms, suicidal tendencies, and anxiety-related symptoms. In particular, those presenting MP reported significantly higher levels of depressive and anxiety-related symptoms than those without. MP represents a clinical aspect that can help to detect more severe cases of EDs and to better understand the complex interplay between ED and mood symptomatology.

RESUMEN

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.

RESUMEN

OBJECTIVE: Assessment of mood in eating disorders (EDs) has important clinical implications, but the current standard psychiatric classification (DSM-5) has limitations. The aim of the current study is to broaden the evaluation of depressive symptomatology by providing a comprehensive and innovative assessment approach in EDs through instruments that capture clinical phenomena of demoralization, subclinical distress, and psychological well-being. METHODS: Seventy-nine patients who met diagnostic criteria for EDs of the Diagnostic and Statistical Manual of Mental Disorders - Fifth edition (DSM-5) were evaluated for depressive symptoms through Paykel's Clinical Interview for Depression, the Structured Clinical Interview for DSM-5 for major depressive episode and persistent depressive disorder, and the Diagnostic Criteria for Psychosomatic Research (DCPR) interview for demoralization. Further, self-report inventories encompassing psychological well-being and distress were used. RESULTS: Guilt, abnormal reactivity to social environment, and depressed mood were the most common depressive symptoms in the sample. DSM-defined depressive disorders were found in 55.7% of patients. The DCPR-demoralization criteria identified an additional 20.3% of the sample that would have been undetected with DSM criteria. Both DSM and DCPR diagnostic categories were associated with compromised psychological well-being and distress. Demoralization, unlike depression, was not associated with the severity of ED symptomatology. CONCLUSION: The findings indicate that a standard psychiatric approach, DSM-5-based, captures only a narrow part of the spectrum of mood disturbances affecting patients with EDs. A broadened clinimetric assessment unravels the presence of demoralization and yields clinical distinctions that may entail prognostic and therapeutic differences among patients who would be otherwise simply labeled as depressed.

RESUMEN

OBJECTIVE: In psychiatry, the presence of residual symptoms after treatment is linked to the definitions of remission and recovery. To identify the presence of residual eating disorder (ED) symptoms and associated non-ED clinical features in remitted and recovered EDs, the current systematic review with meta-analysis was performed. METHOD: A systematic review was conducted on residual ED symptoms and non-ED clinical features including comorbid psychopathology, neurophysiological functioning, cognitive functioning, and quality of life in ED patients considered remitted or recovered. To examine residual ED symptoms, meta-analyses were performed while considering age, study quality, remission, and recovery criteria strictness as moderators. Sensitivity, publication bias, and heterogeneity analyses were also conducted. RESULTS: The 64 studies selected for the systematic review underscored the presence of residual ED symptoms in anorexia nervosa (AN) and bulimia nervosa (BN), and impairments and deficits in the additional features examined. From the 64 studies, 31 were selected regarding residual ED symptoms in AN for meta-analysis. Large effect sizes indicated that remitted/recovered AN patients reported significantly lower body mass index (Hedges' g = -0.62[-0.77, -0.46]) and significantly greater symptomatology in terms of ED examination-questionnaire (Hedges'g = 0.86 [0.48,1.23]) and ED inventory (Hedges' g = 0.94[0.64,1.24]) than healthy controls, independently of remission and recovery criteria strictness, age, and study quality. DISCUSSION: The presence of residual ED symptoms in AN is quantitatively supported, whereas the presence of residual ED symptoms in BN should be further investigated. Data on binge-eating disorder are missing. Future research should use consistent, multicomponent, and standardized comparable indicators of recovery.


OBJETIVO: En psiquiatría, la presencia de síntomas residuales después de tratamiento está ligado a las definiciones de remisión y recuperación. Para identificar la presencia de síntomas residuales del trastorno de la conducta alimentaria (TCA) y características clínicas no de TCA asociadas en pacientes remitidos y recuperados de TCAs, se realizó la presente revisión sistemática con meta-análisis. MÉTODO: Se realizó una revisión sistemática en síntomas residuales de TCA y en características clínicas no de TCA incluyendo psicopatología comórbida, funcionamiento neurofisiológico, funcionamiento cognitivo, y calidad de vida en pacientes con TCA considerados remitidos o recuperados. Para examinar los síntomas residuales de TCA se realizaron meta-análisis considerando edad, calidad del estudio, criterios de remisión y recuperación estrictos como moderadores. También se realizaron análisis de sensibilidad, sesgo de publicación y heterogenicidad. RESULTADOS: Los 64 estudios seleccionados para la revisión sistemática destacaron la presencia de síntomas residuales de TCA en anorexia nervosa (AN) y bulimia nervosa (BN), y alteraciones y déficits en las características adicionales examinadas. De los 64 estudios, 31 fueron seleccionados para meta-análisis por los síntomas residuales de TCA en AN. Las medidas de efecto mayor indicaron que los pacientes remitidos/recuperados de AN reportaron índices de masa corporal significativamente menores (Hedges' g = -0.62[-0.77,-0.46]) y significativamente mayor sintomatología en términos del Cuestionario de Evaluación de TCA (Eating Disorder Examination-Questionnaire) (Hedges' g = 0.86 19 [0.48,1.23]) y el Inventario de TCA (Eating Disorder Inventory) (Hedges' g= 0.94[0.64,1.24]) que los controles sanos, independientemente de lo estricto de los criterios de remisión y recuperación, edad y calidad del estudio. DISCUSIÓN: La presencia de síntomas residuales de TCA en AN es apoyada cuantitativamente, mientras que la presencia de síntomas residuales de TCA en BN necesita ser investigada a mayor profundidad. Los datos en trastorno de atracones están ausentes. Las investigaciones futuras deberían utilizar indicadores de recuperación consistentes, de múltiples componentes y estandarizados.

RESUMEN

Dysfunctional cognitions such as irrational beliefs (IBs) of Ellis' rational emotive behavior therapy (REBT) model and cognitive distortions (CDs) or cognitive errors from Beck's cognitive behavioral therapy (CBT) model are known to correlate with depressive symptomatology. However, most studies focus on one cognitive theoretical model in predicting psychopathology. The current study examined the relationship between both IBs and CDs in predicting depression. A college-age sample of 507 participants completed the Attitudes and Beliefs Scale-2, the Cognitive Distortions Scale, and the Beck Depression Inventory-II. Half of the sample showed minimal depression, while the remaining sample exhibited mild-moderate (37.4%) to severe (11.1%) depression symptomatology. Through regression analyses, the study aimed to examine whether IBs accounted for more of the variance in depression symptomatology after the effects of CDs were considered. Moreover, it tested whether CDs served as a moderator or mediator between IBs and depression. Each of Ellis' IBs (demandingness, awfulizing, self-downing, and low frustration tolerance) accounted for significantly more variance in depression after the variance of CDs was entered with the IB of self-downing explaining the most variance in depression severity. Moreover, while no moderation effect was found, CDs partially mediated the effect of IBs on depression. Both IBs and CDs contributed unique variance in predicting depression. Findings support the clinical notion that IBs and CDs are associated as well as highlight the clinical utility of both conceptualizations of dysfunctional cognitions in explaining depressive symptomatology. Clinicians might consider that each dysfunctional cognition might not be subject to change if not directly targeted. Rather than choosing to focus exclusively on IBs or CDs underlying negative automatic thoughts, psychotherapeutic efforts might benefit from identifying and challenging both types of dysfunctional cognitions.

RESUMEN

Eating disorder (ED) patients are frequently characterized by feelings of inefficacy. The aims of the present study were to investigate subjective incompetence and whether its early modification in therapy is associated with treatment response in terms of both psychological distress and well-being. Sixty female ED outpatients undergoing cognitive-behaviorally-based treatment integrated with nutritional rehabilitation were evaluated using: Subjective Incompetence Scale (SIS), Eating Attitudes Test (EAT), Beck Depression Inventory (BDI-II), and Psychological Well-being Scales (PWB). Repeated measures analysis of variance to test changes in variables and hierarchical regression analyses to test the predictive role of SIS were conducted. Significant improvements in SIS, and in distress measures (EAT, BDI-II) and well-being (PWB) were observed by mid-treatment. Early SIS reductions in patients significantly predicted reductions in EAT-food and bulimic preoccupations, EAT-oral control and EAT-dietary restraint scores, independently of initial depressive symptomatology and illness severity. Gains in three PWB dimensions (environmental mastery, purpose in life, self-acceptance) were also predicted by changes in subjective incompetence. Treatment response might be enhanced by targeting more specifically persistent feelings of incompetence associated with ED symptomatology and compromised psychological well-being dimensions. Such paucities in positive functioning are central themes in EDs and if left untreated might represent obstacles to recovery.

RESUMEN

Psychological well-being changes following cognitive-behavioral therapy-based treatment were investigated in outpatients with eating disorders (ED). While it is known that CBT reduces symptomatology in EDs, less is known about how changes in positive functioning may ensue. One-hundred and eighty five ED outpatients were analyzed for pre-treatment and post-treatment changes in psychological well-being (PWB) by last observation carried forward - Wilcoxon signed rank tests. Significant gains in all PWB dimensions were found, with moderate effect size correlations in environmental mastery (r=-.418), personal growth (r=-.351) and self-acceptance (r=-.341). A subsample of patients in remission (n=51) was selected and compared to healthy controls in PWB post-treatment scores through Mann-Whitney U tests. Remitted patients showed significantly lower psychological well-being in two dimensions compared to controls: PWB-positive relations (r=-.360) and PWB-self-acceptance (r=-.288). However, more than 50% of ED outpatients in remission had PWB scores that fell below the 50th percentile of healthy controls in all psychological well-being dimensions, despite significant treatment response. Several mechanisms of psychological well-being change following CBT-based treatment are discussed. The assessment of treatment outcome in EDs may benefit from considering changes in positive functioning such as psychological well-being, in addition to the standard measurement of BMI, symptomatology and behavioral parameters. CBT-based treatment outcomes may be strengthened by promoting the development of optimal domains particularly in the interpersonal realm, such as building of quality and warm relationships and focusing on enhancing self-acceptance.

RESUMEN

OBJECTIVE: Positive functioning is widely neglected in research on eating disorders (EDs). The aim of this exploratory study was to assess psychological well-being (PWB) in out-patients with ED and in controls. METHOD: The authors assessed PWB in 245 out-patients with EDs [105 with bulimia nervosa (BN), 57 with anorexia nervosa (AN), and 83 with binge eating disorder (BED) who met DSM-IV-TR] and 60 controls. They tested whether PWB was associated with eating attitude test (EAT) scores and if such associations differed among ED groups while taking into account confounding variables. RESULTS: Significant differences between groups in all PWB scales were found. While individuals with BN reported significantly lower scores in all PWB dimensions than healthy controls, patients with BED scored significantly lower than controls in PWB autonomy, environmental mastery, and self-acceptance scales. Patients with AN showed similar scores to controls in all PWB dimensions, except for positive relationships and self-acceptance. In all ED groups, most PWB dimensions resulted significantly and negatively associated with EAT scales, except for AN where oral control was found to positively correlate with a high sense of purpose in life. All results were maintained even after adjusting for possible confounding variables. DISCUSSION: Patients with EDs reported an impairment in PWB. The paucity of PWB was not necessarily dependent on the presence of high levels of psychological distress and on the severity of the disorder. Such assessments may therefore yield a more comprehensive evaluation in this clinical population.

RESUMEN

Cognitive reappraisal is a commonly used and highly adaptive strategy for emotion regulation that has been studied in healthy volunteers. Most studies to date have focused on forms of reappraisal that involve reinterpreting the meaning of stimuli and have intermixed social and non-social emotional stimuli. Here we examined the neural correlates of the regulation of negative emotion elicited by social situations using a less studied form of reappraisal known as distancing. Whole brain fMRI data were obtained as participants viewed aversive and neutral social scenes with instructions to either simply look at and respond naturally to the images or to downregulate their emotional responses by distancing. Three key findings were obtained accompanied with the reduced aversive response behaviorally. First, across both instruction types, aversive social images activated the amygdala. Second, across both image types, distancing activated the precuneus and posterior cingulate cortex (PCC), intraparietal sulci (IPS), and middle/superior temporal gyrus (M/STG). Third, when distancing one's self from aversive images, activity increased in dorsal anterior cingulate (dACC), medial prefrontal cortex (mPFC), lateral prefrontal cortex, precuneus and PCC, IPS, and M/STG, meanwhile, and decreased in the amygdala. These findings demonstrate that distancing from aversive social cues modulates amygdala activity via engagement of networks implicated in social perception, perspective-taking, and attentional allocation.

RESUMEN

BACKGROUND: Emotional instability is a defining feature of borderline personality disorder (BPD); yet, little is understood about its underlying neural correlates. One possible contributing factor to emotional instability is a failure to adequately employ adaptive cognitive regulatory strategies such as psychological distancing. METHODS: To determine whether there are differences in neural dynamics underlying this control strategy between BPD patients and healthy control (HC) subjects, blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging signals were acquired as 18 BPD and 16 HC subjects distanced from or simply looked at pictures depicting social interactions. Contrasts in signal between distance and look conditions were compared between groups. RESULTS: Borderline personality disorder patients showed a different pattern of activation compared with HC subjects when looking at negative versus neutral pictures. When distancing versus looking at negative pictures, both groups showed decreased negative affect ratings and increased activation of the dorsolateral prefrontal cortex, areas near/along the intraparietal sulcus (IPS), ventrolateral prefrontal cortex, and posterior cingulate/precuneus regions. However, the BPD group showed less BOLD signal change in dorsal anterior cingulate cortex and IPS, less deactivation in the amygdala, and greater activation in the superior temporal sulcus and superior frontal gyrus. CONCLUSIONS: Borderline personality disorder and HC subjects display different neural dynamics while passively viewing social emotional stimuli. In addition, BPD patients do not engage the cognitive control regions to the extent that HCs do when employing a distancing strategy to regulate emotional reactions, which may be a factor contributing to the affective instability of BPD.
