RESUMO
OBJECTIVE: Shame is a powerful self-conscious emotion that is often experienced by individuals with eating disorders (EDs). While the association between EDs and shame is well-established, there is limited research investigating the contribution of pre-treatment shame to clinical outcomes. METHOD: Participants (N = 273) received outpatient cognitive-behavioral therapy for eating disorders (CBT-ED). We investigated pre-treatment shame as a predictor of dropout and as a moderator of change in ED psychopathology and clinical impairment from pre-treatment to post-treatment. We also explored the potentially moderating roles of body mass index, ED diagnostic category, and co-occurring anxiety and depression diagnoses. RESULTS: Shame improved substantially (d = 1.28) despite not being explicitly targeted in treatment. Pre-treatment shame did not predict treatment dropout. Individuals high in shame started and ended treatment with higher ED symptoms and impairment than those with low shame. The contribution of pre-treatment shame on the degree of change in symptoms/impairment depended critically on whether analyses controlled for pre-treatment symptoms/impairment. When those were controlled, high pre-treatment shame was associated with substantially less improvement in ED symptoms and impairment. There was some evidence that ED diagnosis and co-occurring depressive diagnoses may moderate the relationship between shame and treatment outcome. Changes in shame were positively associated with changes in ED symptoms and clinical impairment. DISCUSSION: A high level of shame at pre-treatment is not a contraindication for CBT-ED as good therapeutic outcomes can be achieved. However, outcomes may be enhanced among individuals high in shame by offering adjunctive interventions that explicitly target shame.
RESUMO
INTRODUCTION: The development and progression of Alzheimer's disease (AD) is a complex process, during which genetic influences on phenotypes may also change. Incorporating longitudinal phenotypes in genome-wide association studies (GWAS) could unmask these genetic loci. METHODS: We conducted a longitudinal GWAS using a varying coefficient test to identify age-dependent single nucleotide polymorphisms (SNPs) in AD. Data from 1877 Alzheimer's Neuroimaging Data Initiative participants, including impairment status and amyloid positron emission tomography (PET) scan standardized uptake value ratio (SUVR) scores, were analyzed using a retrospective varying coefficient mixed model association test (RVMMAT). RESULTS: RVMMAT identified 244 SNPs with significant time-varying effects on AD impairment status, with 12 SNPs on chromosome 19 validated using National Alzheimer's Coordinating Center data. Age-stratified analyses showed these SNPs' effects peaked between 70 and 80 years. Additionally, 73 SNPs were linked to longitudinal amyloid accumulation changes. Pathway analyses implicated immune and neuroinflammation-related disruptions. DISCUSSION: Our findings demonstrate that longitudinal GWAS models can uncover time-varying genetic signals in AD. Highlights: Identify time-varying genetic effects using a longitudinal GWAS model in AD.Illustrate age-dependent genetic effects on both diagnoses and amyloid accumulation.Replicate time-varying effect of APOE in a second dataset.
RESUMO
Eating disorders have serious physical, mental and social consequences that can affect the quality of life of the sufferer. This study aimed to evaluate the relationship between the severity of ED-related psychopathology and clinical impairment in adolescents with anorexia nervosa (AN) as well as their perception of health-related quality of life. Eighty-six Spanish young women with AN completed a set of questionnaires assessing eating disorder pathology, clinical impairment, and quality of life. The set included the following instruments: the Eating Disorder Examination Questionnaire, Clinical Impairment Assessment, Short Form-12 Item Health Survey, and the Eating Disorder-Specific Heath-Related Quality of Life instrument. Descriptive and regression analyses were applied to identify associations between variables. Higher scores on clinical impairment domains were associated with greater impairment of mental and physical health. Moreover, clinical impairment domains and concerns due to ED were related to a lower quality of life. In conclusion, adolescents with AN have a poor quality of life. Moreover, the findings suggest that the clinical features of impairment may serve as severity indicators of quality of life.
RESUMO
The Hierarchical Taxonomy of Internalizing Dimensions for Eating Disorders model positions eating disorder (ED) symptoms on an internalizing dimension alongside anxiety and mood symptoms. Symptom dimensions falling under the internalizing subfactors of distress (e.g., social anxiety) and fear/avoidance (e.g., panic, compulsions, checking) may differentially guide treatment. We examined relations between fear of negative evaluation and intolerance of uncertainty (core features of social anxiety and obsessive-compulsive disorder, respectively) and ED-related impairment and potential diagnostic differences. We hypothesized that: (a) fear of negative evaluation and intolerance of uncertainty would be related to ED-related impairment, (b) the relation between fear of negative evaluation and impairment would be strongest among individuals with "binge-eating syndromes" (i.e., bulimia nervosa [BN], binge-eating disorder [BED]), and (c) the relation between intolerance of uncertainty and impairment would be strongest among individuals with "weight-phobic syndromes" (i.e., anorexia nervosa [AN], BN, atypical AN). Participants (N = 236) included children/adolescents and adults evaluated for outpatient ED treatment. Participants completed questionnaires and semi-structured diagnostic interviews. Greater fear of negative evaluation and greater intolerance of uncertainty were related to greater clinical impairment, and the strength of these relations depended on ED diagnosis. Fear of negative evaluation was related to impairment among individuals with AN and atypical AN, and intolerance of uncertainty was related to impairment for individuals with AN, BN, and atypical AN. We identified fear of negative evaluation and intolerance of uncertainty as correlates of clinical impairment, highlighting the potential utility of developing treatments to target these internalizing constructs, especially for individuals with weight-phobic syndromes.

Abstract Introduction Eating disorders (EDs) affect up to 13% of young people and are associated with significant morbidity and mortality. Nevertheless, important, internationally recognized instruments for brief ED screening (Sick Control One Stone Fat Food Questionnaire [SCOFF]), symptom severity assessment and diagnosis (Eating Disorder Examination Questionnaire [EDE-Q]) and assessment of ED-associated psychosocial impairment (Clinical Impairment Assessment Questionnaire [CIA]) were not yet available in Brazilian Portuguese. Our objective was to perform the cross-cultural adaptation and translation into Brazilian Portuguese of the instruments SCOFF, EDE-Q and CIA. Method The process involved a series of standardized steps, as well as discussions with experts. First, the relevance and adequacy of the scales' items to our culture and population were extensively discussed. Then, two independent groups translated the original documents, creating versions that were compared. With the participation of external ED experts (i.e., who did not take part in the translation process), synthesized versions were produced. The syntheses were then applied to a focal group of patients with ED (n = 8). After that step, a preliminary version of the three scales in Brazilian Portuguese was produced and sent for back-translation by two English native speakers, who worked independently. A synthesis of the back-translations, along with the preliminary versions in Brazilian Portuguese, were sent to the original authors. Results The Brazilian Portuguese versions of SCOFF, EDE-Q and CIA were approved by the original authors and are now available for use. Conclusion This study provides important tools for the ED research field in Brazil.
