Classification of subtypes of patients with eating disorders by correspondence analysis.
Ontology highlight
ABSTRACT: Background
Grouping eating disorders (ED) patients into subtypes could help improve the establishment of more effective diagnostic and treatment strategies.Aim
To identify clinically meaningful subgroups among subjects with ED using multiple correspondence analysis (MCA).Methods
A prospective cohort study was conducted of all outpatients diagnosed for an ED at an Eating Disorders Outpatient Clinic to characterize groups of patients with ED into subtypes according to sociodemographic and psychosocial impairment data, and to validate the results using several illustrative variables. In all, 176 (72.13%) patients completed five questionnaires (clinical impairment assessment, eating attitudes test-12, ED-short form health-related quality of life, metacognitions questionnaire, Penn State Worry Questionnaire) and sociodemographic data. ED patient groups were defined using MCA and cluster analysis. Results were validated using key outcomes of subtypes of ED.Results
Four ED subgroups were identified based on the sociodemographic and psychosocial impairment data.Conclusion
ED patients were differentiated into well-defined outcome groups according to specific clusters of compensating behaviours.

Project description:Background: Mentalizing, the mental capacity to understand oneself and others in terms of mental states, has been found to be reduced in several mental disorders. Some studies have suggested that eating disorders (EDs) may also be associated with impairments in mentalizing. The aim of this work is to investigate the possible presence of mentalizing subtypes in a sample of patients with EDs. Method: A sample of patients with eating disorders (N = 157) completed a battery of measures assessing mentalization and related variables, including the Reflective Functioning Questionnaire (RFQ), the Difficulties in Emotion Regulation Strategies (DERS), the Interpersonal Reactivity Index (IRI). Clinicians rated patients in relation to imbalances in different dimensions of mentalization to prementalizing modes and attachment style by using the Mentalization Imbalances Scale, the Modes of Mentalization Scale (MMS), and the Adult Attachment Questionnaire. A latent profile analysis was conducted to test the possible presence of different subgroups. MANOVA was used to test the possible differences between the four mentalizing profiles in relation to emotion dysregulation (DERS), empathy (IRI), and adequate and impairments in mentalizing (MMS and RFQ). Results: The latent profile analysis suggested the presence of four different profiles in relation to impairments in the dimensions of mentalization: (1) affective/self/automatic imbalances, (2) external imbalance, (3) cognitive/self/automatic imbalances, and (4) cognitive/other/automatic imbalances. Patients belonging to profile 1 are characterized by the prevalence of affective mentalization that overwhelms the capacity to reflect on mental states with an imbalance on the self-dimension; profile 2 patients are excessively focused on the external cues of mentalization; profile 3 patients are characterized by an over-involvement on the cognitive and self-facets of mentalization, with an impairment in adopting the other mind perspective; and profile 4 patients have similar impairments compared to profile 3 patients but with an excessive focus on others and deficits in self-reflection. These profiles were heterogeneous in terms of EDs represented in each group and presented significant differences on various variables such as attachment style, emotion dysregulation, empathy, interpersonal reactivity, and reflective function. This study represents, so far, the first work that confirms the presence of different mentalizing patterns in ED patients. Conclusions: ED patients can be classified in relation to impairments in different dimensions of mentalization above and beyond ED diagnosis.

Project description:Although previous research has supported the importance of anxiety as an etiological and maintenance factor for eating disorders, the specific mechanisms are not well understood. The role of anxiety in the context of eating behavior is especially unclear. The purpose of this study was to identify anxiety-eliciting eating situations and anxiety management strategies patients use to mitigate anxiety experienced in the context of eating as determined by diagnostic groups and symptom patterns. Fifty-three eating disorder outpatients were administered the Eating and Anxiety Questionnaire (EAQ) and the Eating Disorder Diagnostic Scale. Ratings indicated significant anxiety in most eating situations, whereas management strategies were more limited yet regularly employed. Factor analysis of the EAQ revealed a 6-factor solution for anxiety management strategies and a 4-factor solution for anxiety-eliciting situations. These results indicate patients with eating disorders report high levels of anxiety associated with eating behaviors but utilize limited yet consistent anxiety management strategies. Effective intervention strategies for managing eating-related anxiety should be incorporated into treatment and may need to be specified for different diagnostic subgroups.

Project description:BackgroundTreatment by venoarterial extracorporeal membrane oxygenation (VA-ECMO) is widely used today, even though it is associated with high risks of complications and death. While studies have focused on the relationship between some of these complications and the risk of death, the relationship between different complications has never been specifically examined, despite the fact that the occurrence of one complication is known to favor the occurrence of others. Our objective was to describe the relationship between complications in patients undergoing VA-ECMO in intensive care unit (ICU) and to identify, if possible, patterns of patients according to complications.Methods and findingsAs part of a retrospective cohort study, we conducted a multiple correspondence analysis followed by a hierarchical ascendant classification in order to identify patterns of patients according to main complications (sepsis, thromboembolic event, major transfusion, major bleeding, renal replacement therapy) and in-ICU death. Our cohort of 145 patients presented an in-ICU mortality rate of 50.3%. Morbidity was high, with 36.5% of patients presenting three or more of the five complications studied. Multiple correspondence analysis revealed a cumulative inertia of 76.9% for the first three dimensions. Complications were clustered together and clustered close to death, prompting the identification of four patterns of patients according to complications, including one with no complications.ConclusionsOur study, based on a large cohort of patients undergoing VA-ECMO in ICU and presenting a mortality rate comparable to that reported in the literature, identified numerous and often interrelated complications. Multiple correspondence analysis and hierarchical ascendant classification yielded clusters of patients and highlighted specific links between some of the complications studied. Further research should be conducted in this area.

Project description:PurposeThis study examined predictors of readmission to inpatient/residential settings in patients with eating disorders. We hypothesized that readmitted patients would report worse transitional care and continuity of care compared to those who were not readmitted.MethodsWe conducted a cross-sectional, online survey of 80 individuals from the US who reported that they were diagnosed with an eating disorder requiring inpatient/residential treatment. Participants completed questionnaires on demographic and clinical characteristics, the Care Transition Model-15, and the Continuity of Care Questionnaire. We analyzed data using univariate statistics and a series of logistic regression models.ResultsParticipants who reported better transitional care (adjusted OR (AOR) = 1.14; p < 0.001), continuity of care during their inpatient or residential stay, including greater transfer of information (AOR = 6.39, p = 0.002), relationships in the hospital (AOR = 6.83, p = 0.003), management of follow-up (AOR = 3.41, p = 0.02), management of communication (AOR = 8.74, p = 0.001), and management of forms (AOR = 9.61, p = 0.002), reported increased odds of being readmitted to an inpatient or residential treatment facility. Use of nasogastric (NG) tube feedings was significantly associated with being readmitted.ConclusionsContrary to our hypotheses, we found that better transitional care and continuity of care were associated with higher odds of readmission.Level of evidenceLevel III, case-control analytic study.

Project description:BackgroundProblems with social-emotional processing are known to be an important contributor to the development and maintenance of eating disorders (EDs). Diminished facial communication of emotion has been frequently reported in individuals with anorexia nervosa (AN). Less is known about facial expressivity in bulimia nervosa (BN) and in people who have recovered from AN (RecAN). This study aimed to pilot the use of computerised facial expression analysis software to investigate emotion expression across the ED spectrum and recovery in a large sample of participants.Method297 participants with AN, BN, RecAN, and healthy controls were recruited. Participants watched film clips designed to elicit happy or sad emotions, and facial expressions were then analysed using FaceReader.ResultsThe finding mirrored those from previous work showing that healthy control and RecAN participants expressed significantly more positive emotions during the positive clip compared to the AN group. There were no differences in emotion expression during the sad film clip.DiscussionThese findings support the use of computerised methods to analyse emotion expression in EDs. The findings also demonstrate that reduced positive emotion expression is likely to be associated with the acute stage of AN illness, with individuals with BN showing an intermediate profile.

Project description:Background Although preliminary studies support the roles of unhealthy parenting styles and maladaptive coping styles in increasing rates of disturbed eating attitudes and behaviors (EAB) and clinically significant feeding and eating disorders (FED), underlying mechanisms have not been well-recognized. This study aims to investigate the factors associated with disturbed EAB and the mediating roles of overcompensation and avoidance coping styles in the relationship between different types of parenting styles and disturbed EAB among patients with FED. Methods A total of 102 patients with FED in Zahedan, Iran, participating in this cross-sectional study (from April to March 2022) completed a sociodemographic information form and self-report measures of parenting styles, maladaptive coping styles, and EAB. Model 4 of Hayes’ PROCESS macro in SPSS was employed to identify and explain the mechanism or process that underlies an observed relationship between study variables. Results The results showed that authoritarian parenting style, overcompensation and avoidance coping styles, and female gender might be related to disturbed EAB. The overall hypothesis that overcompensation and avoidance coping styles mediated the effect of fathers’ and mothers’ authoritarian parenting styles on disturbed EAB was also supported. Conclusions Our findings highlighted the necessity of evaluating particular unhealthy parenting styles and maladaptive coping styles as the important possible risk factors in the development and maintenance of higher level of disturbance in EAB among patients with FED. However, more research is needed to explore individual, family, and peer risk factors for disturbed EAB among these patients.

Project description:ObjectiveIn 2015, the Academy for Eating Disorders collaborated with international patient, advocacy, and parent organizations to craft the 'Nine Truths About Eating Disorders'. This document has been translated into over 30 languages and has been distributed globally to replace outdated and erroneous stereotypes about eating disorders with factual information. In this paper, we review the state of the science supporting the 'Nine Truths'.MethodsThe literature supporting each of the 'Nine Truths' was reviewed, summarized and richly annotated.ResultsMost of the 'Nine Truths' arise from well-established foundations in the scientific literature. Additional evidence is required to further substantiate some of the assertions in the document. Future investigations are needed in all areas to deepen our understanding of eating disorders, their causes and their treatments.ConclusionsThe 'Nine Truths About Eating Disorders' is a guiding document to accelerate global dissemination of accurate and evidence-informed information about eating disorders.

Project description:PurposeThis study aimed to estimate the prevalence of eating disorders (EDs) in musicians, and to evaluate their relation to perfectionism, stress, anxiety and depression.MethodsIt examined: (1) the prevalence of EDs using the Eating Disorder Examination Questionnaire (EDE-Q), body mass index (BMI) and self-reports, (2) psychological risk factors using the Depression Anxiety Stress Scale (DASS-21) and perfectionism inventory and (3) demographic details, information about musical and career development, lifestyle, eating habits and health. A survey was distributed worldwide and a total of 301 English-speaking musicians aged 18 years and older participated.ResultsOur screening tools for EDs showed a high prevalence of EDs in musicians: the EDE-Q Global Score (EDE-QGS) showed pathological values in 18.66% of the musicians and when questioned about lifetime prevalence, 32.3% of the musicians answered positively. The median BMI was within the normal range. Regarding general mental health, the DASS-21 showed that depression and stress were severe, anxiety was extremely severe and the perfectionism inventory composite score was 26.53. There was no significant difference on the EDE-QGS between musicians who perform different types of music, but music students, professionals, soloists and musicians travelling overseas had a higher percentage of pathological EDE-QGS. Perfectionism was higher in classical musicians and there was a low positive correlation between EDE-QGS and the risk factors: perfectionism, depression, anxiety, stress, peer pressure and social isolation.ConclusionEDs are prevalent in musicians and possible risk factors are their increased perfectionism, depression, anxiety and stress due to the demands of their job.
