Bridging Perspectives: Exploring the Convergence of Clinimetrics and Network Theory in Mental Health Assessment and Conceptualization.

Background: Clinimetrics and network analysis are two methodological approaches that, despite different origins, share the goal of improving mental health clinical assessment beyond the limitations of classical psychometrics. Despite their common goal and comparable conceptualization of clinical assessment, the potential connection and integration between these approaches has not been explored. The aim of this review is to identify meeting points for the potential integration of clinimetrics and network theory. Methods: A literature review was conducted by examining key works in clinimetrics and network theory and comparing similar concepts from the two approaches. Results: Two main areas of theoretical and methodological convergence and complementarity between clinimetrics and network theory were identified, as follows: the characteristics of clinical indexes and the strategies to assess and organize complex clinical data. These topics encompassed sub-topics related to the influence of individual symptoms on clinical presentation, longitudinal assessment of conditions, influence of comorbidities, and standardized procedures for case formulation. Conclusions: Results provide an indication of the potential for integration for these approaches in a single, clinically oriented methodology for psychological and psychiatric illness conceptualization and assessment. Despite the literature search strategy limitations, the results provide a basis for further exploring the potential for developing an integrated methodology for clinical assessment and treatment planning.

Protocol for a Randomized Controlled Trial Testing the Efficacy of a Transdiagnostic Virtual Reality-Based Intervention for the Reduction of Unhealthy Lifestyles and Behaviors in the General Population.

Virtual reality (VR) is a valuable tool for the treatment and prevention of psychiatric disorders and dysfunctional behaviors. Although VR software is mainly developed following a disorder-specific approach, this randomized controlled trial (RCT) will test the efficacy of a new transdiagnostic VR application (H.O.M.E. VR-based psychological intervention) in improving dysfunctional behaviors, three transdiagnostic factors concurrently (emotion regulation, experiential avoidance, and psychological flexibility), and stress. Three groups screened as at-risk for nicotine dependence, alcohol abuse, and eating disorders will be assigned to the H.O.M.E. VR intervention and compared to a waiting-list (WL) condition. Participants will be assessed before and after the H.O.M.E. intervention/WL and at the 3- and 6-month follow-ups in the levels of the displayed dysfunctional behavior, the three transdiagnostic factors, and stress. Changes in dysfunctional behaviors, transdiagnostic factors, and stress in each population VR group and differences in such improvements between each population of the VR and WL groups will be evaluated using mixed-model repeated measure analyses of variance. It is expected that, after the H.O.M.E. intervention and at follow-ups, participants will display improvements in physical and psychological health compared to controls. The H.O.M.E. protocol is expected to result in a cost-effective option to tackle cognitive-behavioral factors shared among several psychopathologies and dysfunctional behaviors.

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 sequential approach in eating disorders: A scoping systematic review.

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.

The Effects of Virtual Reality in Targeting Transdiagnostic Factors for Mental Health: A Systematic Review of the Literature.

Virtual reality (VR) was found to be effective in the treatment of several specific psychopathologies. However, the effects of VR-based interventions beyond the disorder-specific approach and their ability to improve transdiagnostic factors of mental disorders are unknown. This PRISMA systematic review was conducted using databases PubMed and PsycINFO, searching articles published between 2010 and September 2022. Keywords "emotion regulation", "cognitive reappraisal", "avoidance", "impulsivity", "aggression", and "disinhibition" were combined with "virtual reality" to retrieve studies showing the effects of VR-based interventions on these transdiagnostic factors. 29 experimental studies and seven case-studies were selected. A total of 23 considered avoidance, eight dealt with emotion regulation, three concerned aggression, two addressed impulsivity, two dealt with cognitive reappraisal, and none examined disinhibition. Most of the studies included anxiety disorder patients (n = 15), especially with specific phobias (n = 8) and social anxiety disorder (n = 4). VR managed to improve all transdiagnostic factors, with results often maintained at follow-ups (n = 21 studies; range: 1-12 months) and similar to traditional interventions (e.g., cognitive-behavioral therapy). Exploring the transdiagnostic potential of VR may help to reduce costs and improve applicability in clinical psychology. While results were promising, further studies are needed for aggression, impulsivity and cognitive reappraisal, especially including follow-ups, comparisons with first-line treatments, and understudied clinical populations.

Network analysis studies in patients with eating disorders: A systematic review and methodological quality assessment.

INTRODUCTION: Network psychometrics has been enthusiastically embraced by researchers studying eating disorders (ED), but a rigorous evaluation of the methodological quality of works is still missing. This systematic review aims to assess the methodological quality of cross-sectional network analysis (NA) studies conducted on ED clinical populations. METHODS: PRISMA and PICOS criteria were used to retrieve NA studies on ED. Methodological quality was evaluated based on five criteria: variable-selection procedure, network estimation method, stability checks, topological overlap checks, and handling of missing data. RESULTS: Thirty-three cross-sectional NA studies were included. Most studies focused on populations that were female, white and, with an anorexia nervosa (AN) diagnosis. Depending on how many criteria were satisfied, 27.3% of studies (n = 9) were strictly adherent, 30.3% (n = 10) moderately adherent, 33.3% (n = 11) sufficiently adherent, and 9.1% (n = 3) poorly adherent. Missing topological overlap checks and not reporting missing data represented most unreported criteria, lacking, respectively, in 63.6% and 48.5% of studies. CONCLUSIONS: Almost all reviewed cross-sectional NA studies on ED report those methodological procedures (variable-selection procedure, network estimation method, stability checks) necessary for a network study to provide reliable results. Nonetheless these minimum reporting data require further improvement. Moreover, elements closely related to the validity of an NA study (controls for topological overlap and management of missing data) are lacking in most studies. Recommendations to overcome such methodological weaknesses in future NA studies on ED are discussed together with the need to conduct NA studies with longitudinal design, to address diversity issues in study samples and heterogeneity of assessment tools. PUBLIC SIGNIFICANCE: The present work aims to evaluate the quality of ED NA studies to support applications of this approach in ED research. Results show that most studies adopted basic procedures to produce reliable results; however, other important procedures linked to NA study validity were mostly neglected. Network methodology in ED is extremely promising, but future studies should consistently include topological overlap control procedures and provide information on missing data.

INTRODUCCIÓN: La psicometría de red ha sido aceptada con entusiasmo por los investigadores que estudian los trastornos de la conducta alimentaria (TCA), pero aún falta una evaluación rigurosa de la calidad metodológica de los trabajos. Esta revisión sistemática tiene como objetivo evaluar la calidad metodológica de los estudios de análisis de redes transversales (NA) realizados en poblaciones clínicas de TCA. MÉTODOS: Se utilizaron los criterios PRISMA y PICOS para recuperar los estudios de NA en TCA. La calidad metodológica se evaluó con base en 5 criterios: procedimiento de selección de variables, método de estimación de red, comprobaciones de estabilidad, comprobaciones de superposición topológica, manejo de datos faltantes. RESULTADOS: Se incluyeron 33 estudios transversales de NA. La mayoría de los estudios se centraron en poblaciones que eran mujeres, blancas y con un diagnóstico de anorexia nerviosa (AN). Dependiendo de cuántos criterios se cumplieron, el 27,3% de los estudios (n = 9) fueron estrictamente adherentes, el 30,3% (n = 10) moderadamente adherentes, el 33,3% (n = 11) suficientemente adherentes, el 9,1% (n = 3) poco adherentes. La falta de controles topológicos de superposición y el no reportar los datos faltantes representó la mayoría de los criterios no reportados, faltando respectivamente en el 63,6% y el 48,5% de los estudios. CONCLUSIONES: Casi todos los estudios transversales revisados de NA sobre TCA reportaron aquellos procedimientos metodológicos (procedimiento de selección de variables, método de estimación de red, comprobaciones de estabilidad) necesarios para que un estudio de red proporcione resultados confiables. No obstante, estos datos mínimos de presentación de reportes requieren mejoras adicionales. Además, en la mayoría de los estudios faltan elementos estrechamente relacionados con la validez de un estudio de NA (controles para la superposición topológica y el manejo de los datos faltantes). Las recomendaciones para superar tales debilidades metodológicas en futuros estudios de NA sobre los TCA son discutidos junto con la necesidad de realizar estudios de NA con diseño longitudinal, para abordar los problemas de diversidad en las muestras de estudio y la heterogeneidad de las herramientas de evaluación.

The Need to Control Thoughts in Eating Disorder Outpatients: A Longitudinal Study on Its Modification and Association with Eating Disorder Symptom Improvement.

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.

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.

Mental Pain in Eating Disorders: An Exploratory Controlled Study.

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.

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.

Disturbed Eating Behaviors in Youth with Type 1 Diabetes: An Exploratory Study about Challenges in Diagnosis.

BACKGROUND: Disordered eating behaviors (DEBs), including diagnosable eating disorders, are quite common and can interfere with optimal type 1 diabetes (T1DM) management. We explored DEBs prevalence in youth with T1DM, proposing news diagnostic subscales, to represent the clinical dimensions associated with feeding and eating disorders (ED); Methods: additionally to SCOFF questionnaire and Diabetes Eating Problem Survey-Revised (DEPS-R), four subscales combined from the original DEPS-R questionnaire were administered to 40 youths with T1DM (15.0 ± 2.6); Results: females showed higher scores than males in DEPS-R original factor 2 ("preoccupations with thinness/weight", p = 0.024) and in DEPS-R proposed "restriction" factor (p = 0.009). SCOFF scores was correlated with original DEPS-R factors 1 ("maladaptive eating habits") and 2 (p < 0.001) and with the newly proposed DEPS-R factors: restriction, disinhibition, compensatory behaviors, diabetes management (all p < 0.02). Diabetes management was the only factor related to glycated hemoglobin level (p = 0.006). Patients with high DEPS-R score (≥20) scored higher than patients with low (<20) DEPS-R score in DEPS-R original factors 1 (p < 0.001) and 2 (p = 0.002) as well as in the proposed factors including restriction, disinhibition, diabetes management (all p < 0.02); Conclusions: the complicated nature of DEBs calls for the development target specific questionnaires to be used as screening tools to detect cases of DEBs and exclude non cases. Early recognition of DEBs in adolescents with T1DM is essential for effective prevention and successful treatment.

An innovative approach for the assessment of mood disturbances in patients with eating disorders.

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.

Mental Pain as a Transdiagnostic Patient-Reported Outcome Measure.

Patient-reported outcomes (PROs) refer to any report coming directly from patients about how they function or feel in relation to a health condition or its therapy. PROs have been applied in medicine for the assessment of the impact of clinical phenomena. Self-report scales and procedures for assessing physical pain in adults have been developed and used in clinical trials. However, insufficient attention has been dedicated to the assessment of mental pain. The aim of this paper is to outline the implications that assessment of mental pain may entail in psychiatry and medicine, with particular reference to a clinimetric index. A simple 10-item self-rating questionnaire, the Mental Pain Questionnaire (MPQ), encompasses the specific clinical features of mental pain and shows good clinimetric properties (i.e., sensitivity, discriminant and incremental validity). The preliminary data suggest that the MPQ may qualify as a PRO measure to be included in clinical trials. Assessment of mental pain may have important clinical implications in intervention research, both in psychopharmacology and psychotherapy. The transdiagnostic features of mental pain are supported by its association with a number of psychiatric disorders, such as depression, anxiety, eating disorders, as well as borderline personality disorder. Further, addressing mental pain may be an important pathway to prevent and diminish the opioid epidemic. The data summarized here indicate that mental pain can be incorporated into current psychiatric assessment and included as a PRO measure in treatment outcome studies.

Residual eating disorder symptoms and clinical features in remitted and recovered eating disorder patients: A systematic review with meta-analysis.

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.

Irrational Beliefs, Cognitive Distortions, and Depressive Symptomatology in a College-Age Sample: A Mediational Analysis.

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.

Methodological Recommendations for Trials of Psychological Interventions.

Recent years have seen major developments in psychotherapy research that suggest the need to address critical methodological issues. These recommendations, developed by an international group of researchers, do not replace those for randomized controlled trials, but rather supplement strategies that need to be taken into account when considering psychological treatments. The limitations of traditional taxonomy and assessment methods are outlined, with suggestions for consideration of staging methods. Active psychotherapy control groups are recommended, and adaptive and dismantling study designs offer important opportunities. The treatments that are used, and particularly their specific ingredients, need to be described in detail for both the experimental and the control groups. Assessment should be performed blind before and after treatment and at long-term follow-up. A combination of observer- and self-rated measures is recommended. Side effects of psychotherapy should be evaluated using appropriate methods. Finally, the number of participants who deteriorate after treatment should be noted according to the methods that were used to define response or remission.
