RESUMO

INTRODUCTION: Eating disorders (ED) represent a group of very complex and serious diagnoses characterized by emotional dysregulation and impulsivity. New approaches are necessary to achieve effective diagnosis and treatments. Shifting biomarker research away from the constraints of diagnostic categories may effectively contribute to a dimensional differentiation across disorders according to neurobiology (e.g., inflammatory biomarkers). Thus, the aim of our study was to identify inflammatory profiles in patients with ED. METHODS: A sample of 100 women with an ED (23.4 ± 8.55 years) and 59 healthy controls (HC) (20.22 ± 4.18 years) was used. K-means cluster analysis was followed to identify inflammatory clusters considering seven blood biomarkers (iNOS, TNFα, COX2, p38, ERK, TBARS and PPARγ). Moreover, a wide assessment of clinical features was conducted. RESULTS: Two distinct clusters were identified. Cluster 1 patients were characterized by higher inflammatory levels of TNF-α, COX2, p38, and ERK, and had more restrictive anorexia diagnosis than cluster 2. Cluster 2 participants showed higher inflammatory levels of iNOS and were older than cluster 1 and controls and had lower BMI than HC. In addition, they had higher levels of bulimic symptoms than those from the cluster 1 and HC, and higher impulsivity than HC. All ED patients (regardless of cluster) showed higher ED symptoms and more trauma than HC. CONCLUSIONS: Our study revealed that inflammatory dysfunction may be linked with clinical endophenotypes in ED, one more restrictive (cluster 1) with an inflammation/oxidative endophenotype more cytokine and MAPK/ERK mediated, and the other more impulsive, with more bulimic symptoms (cluster 2) with NO free radical high output source iNOS. Trauma seems to be a vulnerability factor for both endophenotypes.

RESUMO

BACKGROUND: Borderline personality disorder (BPD) and eating disorders (ED) are both disorders with emotional dysregulation that may share some similar biological underpinnings, leading to oxidative/inflammatory alterations. Unfortunately, to date, no studies have assessed the relationship between clinical features, inflammatory alterations and childhood trauma across these disorders. Our aim was to identify the potential common and disorder-specific inflammatory pathways and examine possible associations between these dysregulated pathways and the clinical features. METHODS: We studied a sample of 108 women (m = 27.17 years; sd = 7.64), divided into four groups: 23 patients with a restrictive ED (ED-R), 23 patients with a bingeeating/ purging ED (ED-P) and 26 patients with BPD; whereas the control group included 23 healthy subjects. Several inflammatory/oxidative parameters: tumor necrosis factor alpha (TNFα), Thiobarbituric Acid Reactive Substances (TBARS), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX2), p38 mitogenactivated protein kinases, ERK mitogen-activated protein kinases and c-Jun NH2- terminal kinase (JNK), and some antiinflammatory antioxidant elements: glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase (CAT), Kelch-like ECHassociated protein (Keap1) were determined in plasma or peripheral blood mononuclear cells. Furthermore, clinical, impulsivity, trauma and eating behavior questionnaires were administered. RESULTS: Three main inflammatory/oxidative components were extracted using principal component analysis (59.19 % of biomarker variance explained). Disorder-specific dysfunction in the inflammatory and oxidative pathways in patients with BPD and ED were revealed by means of relationships with specific principal components (p < .01). BPD patients showed higher levels of a component featured by elevated levels of JNK and lower of GPx and SOD. ED-R and impulsivity were associated with a component featured by the activation of ERK and negative influence of Keap1. The component featured by the suppression of catalase and COX2 was associated with both ED subtypes and trauma exposure. CONCLUSION: Several risk factors such as trauma, impulsivity and eating disorder symptoms were transdiagnostically associated with some inflammatory alterations regardless of diagnosis. These findings suggest that the clinical profile comprising trauma exposure and an emotional dysregulation disorder might constitute a specific endophenotype highly linked with inflammatory alterations.

RESUMO

Introducción. La elevada comorbilidad entre el trastorno límite de la personalidad (TLP) y los trastornos de la conducta alimentaria (TCA) pone de manifiesto la necesidad de establecer modelos transdiagnósticos, donde la impulsividad podría tener un papel relevante en las manifestaciones dela conducta autolítica. Objetivos: 1) Comparar los niveles de impulsividad y conducta autolítica entre personas con TLP, personas con TCA y controles. 2) Predecir la presencia de conductas autolíticas a partir de la impulsividad y otras variables clínicas relevantes, como la vivencia de acontecimientos traumáticos y la sensibilidad al rechazo. Método. 108 mujeres (23 controles; 29 con diagnóstico de TCA restrictivo (TCAr); 21 con diagnóstico de TCA purgativo (TCAp); y 35 con diagnóstico de TLP) fueron evaluadas a través de la Escala de Impulsividad de Barratt, el Cuestionario para Experiencias Traumáticas y el Cuestionario de Sensibilidad al Rechazo. La información sobre conducta autolítica fue recogida a través de entrevista e historia clínica. Resultados. Se encontraron diferencias en las puntuaciones de impulsividad y conducta autolítica entre los grupos, encontrándose mayor impulsividad en los grupos TLP y TCAp, y mayores índices de conducta autolítica en el grupo TLP seguido de ambos grupos de TCA. Por otro lado, la impulsividad predecía los intentos de suicidio, y junto con la sensibilidad al rechazo interpersonal predecía las autolesiones no suicidas (ANS).Conclusión. La impulsividad es una variable dimensional en el TLP y en los TCA, que a su vez juega un papel relevante en la predicción de las conductas autolíticas. (AU)


Introduction. High comorbidity between borderline personality disorder (BPD) and eating disorders (ED) shows the necessity of developing transdiagnostic models, where impulsivity could play a relevant role in the manifestations ofself-injurious behaviour. Objectives: 1) To compare the levelsof impulsivity and self-injurious behaviour among peoplewith BPD, people with ED and controls. 2) To predict the presence of self-injurious behaviour based on impulsivity andother relevant clinical variables, such as the experience oftraumatic events and sensitivity to rejection. Methods. 108 women (23 controls; 29 with a diagnosis of restrictive ACT (rED); 21 with a diagnosis of purgative ACT(pED); and 35 with a diagnosis of BPD) were assessed usingthe Barratt Impulsivity Scale, the Traumatic Experiences Questionnaire and the Sensitivity to Rejection Questionnaire. Information about self-injurious behaviour was collectedthrough interview and clinical history. Results. Differences in impulsivity and self-injurious behaviour scores were found between the groups, with higherimpulsivity in the BPD and pED groups, and higher rates ofself-injurious behaviour in the BPD group followed by both ED groups. On the other hand, impulsivity predicted suicideattempts, and together with sensitivity to interpersonal rejection predicted nonsuicidal self-harm (NSSH). Conclusion. Impulsivity is a dimensional variable in BPD and ED, which in turn plays a relevant role in the prediction of self-injurious behaviour. (AU)

RESUMO

Eating disorders (ED) are severe mental disorders that may result in significant functional impairment and disability. Neuropsychological studies have consistently found impaired executive function (EF) among ED patients. EF is particularly involved in fundamental skills of daily living and in behavioral and emotional regulation. In this study, impairment of executive functioning is investigated in patients with eating disorders and the associations with clinical features and clinical subtypes are analyzed. METHOD: 75 female patients (m = 22.01 years, sd = 9.15) with eating disorder (43 restrictive anorexia, 30 binge-eating anorexia and 13 bulimia nervosa) and 37 healthy controls (m = 18.54 years, sd = 4.21) were included in the study. An extensive assessment of executive function domains (verbal fluency, set shifting, attention span, selective attention, working memory, inhibitory control and processing speed) was carried out in both groups. Clinical scales for food intake restriction, binge-eating/purging, depression, anxiety and impulsivity were also administered and correlated with scores on executive function tests. RESULTS: Patients with an ED had significantly lower scores than healthy controls in performance of several executive function tests, particularly in set shifting, interference control and processing speed (p < .01, in all three domains). Executive function impairment was related to anxious, depressive and eating disorder symptoms (p < .05), regardless of clinical subtype. CONCLUSIONS: Executive function impairment in eating disorders is associated with greater ED symptomatic severity and might involve a negative treatment outcome. Therefore, cognitive remediation techniques should probably be considered in a number of severe patients with ED.

RESUMO

AIM: To examine women's evaluations of quality of care from their perspectives. BACKGROUND: Assessing women's satisfaction with the quality of care they receive during childbirth is an important component of care quality that should be analysed. Evidence suggests that childbirth experience has an important impact on women's health. Therefore, taking into account the perceptions of women about quality is a means to improve care. However, studies examining care quality in this setting remain scarce. DESIGN: Mixed-methods explanatory sequential design. METHODS: A national survey with a sample of 1082 participants, and 15 semi-structured interviews. Data collection occurred between January 2017 and January 2019. Quantitative data were obtained through a validated scale, the Quality from the Patient's Perspective-Intrapartal questionnaire, whose score can range from 1 (minimum satisfaction) to 4 (maximum satisfaction). Semi-structured interviews were conducted for qualitative data. Descriptive statistics, group comparison and qualitative content analysis were included in data analysis. RESULTS: The mean score on the QPP-I tool was high (3.13; SD 0.74). Variables that had the most influence on the experience were type of birth, type of perineal trauma, admission of the baby, time since birth, home-birth, parity and duration of labour. Data from the qualitative interviews identified five themes that explained women's experiences with the quality of care. Previous expectations influence the emotions they have regarding the experience. Relationships with professionals and their social skills are fundamental for the evaluation of quality. The separation of the newborn appears as a factor that worsens the appreciation of women. Good pain management and continuity of care by specialists are also named as key elements of the quality of care. CONCLUSION: Findings demonstrate that experience with childbirth care is of utmost importance for women. They also show the indisputable need to listen to their opinions and assessments when lines of improvement of quality are identified. IMPACT: This study provides information that can improve the care that women receive during their childbirths. Using their opinions will make them feel an active part of the system and in this way, we will be closer to achieve excellence in our services.

RESUMO

People with eating disorders show impaired health-related quality of life (HRQoL). We aimed to investigate the relative role of physical and mental factors and stage of change as possible predictors of HRQoL in a group of Spanish women (n = 124) with eating disorders. For this purpose, initial and follow-up data were obtained after 6 months from patients attending an outpatient treatment unit for eating disorders. The determinants of the physical and mental domains of the Medical Outcomes Survey Short-form Health Survey (SF-36) questionnaire were investigated in the total sample and separately based on the eating disorder diagnosis by multiple linear regression. Lower scores in the physical component of the SF-36 questionnaire were associated with the presence of a higher body mass index (BMI) at follow-up as well as a higher score in the "action" component of the Attitudes towards Change in Eating Disorders Questionnaire (ACTA). Conversely, a higher index in the EuroQoL-5D overall quality of life questionnaire (EQ-5D) and the presence of obsessive compulsive disorder were associated with a higher score in the physical dimension. The instrument used demonstrated the ability to assess changes associated with the physical component of these patients over the period studied, and the analysis provided more information and specific data on different aspects of HRQoL, thus allowing a more detailed analysis of the information.

RESUMO

AIM: We aim to investigate the association between the presence of eating disorders and both Internet addiction (IA) and Facebook addiction (FA) in women suffering from eating disorders. METHODS: A total of 124 women completed three instruments: the Internet Addiction Test (IAT), the Bergen Facebook Addiction Scale (BFAS) and a sociodemographic questionnaire. RESULTS: The proportion of FA was 37.9%. The distribution of risk of IA was 21.8%. When the risk of Internet or Facebook addiction was compared with respect to eating disorders, no significant differences were found between groups (P = 0.146 and P = 0.086, respectively). Age and Body Mass Index (BMI) were predictors of BFAS scores; the standardized beta coefficient (ß) for age was -0.463 (P ≤ 0.001), while for BMI it was 3.44; (P = 0.001) being a positive predictor of BFAS scores. For IAT scores, ß age (negatively) = -0.415; (P < 0.001) and ß for weight (positively) 3.657; (P < 0.001) were identified. CONCLUSIONS: The presence of an eating disorder does not seem to be a factor that characterizes the risk of Internet or Facebook addiction in our sample. As information regarding the potential association between Internet and Facebook addiction and the presence of eating disorders is limited, we encourage further studies on this topic.

RESUMO

OBJECTIVES: The study aimed to examine whether dissociation and attitudes towards change were associated with the psychopathology in patients with eating disorders (EDs) at 1-year follow-up. METHOD: The study included 110 females with anorexia nervosa and bulimia nervosa (48 and 62 respectively). At the beginning of the study and 1 year later, they were assessed by means of the following questionnaires: Dissociative Experiences Scale, Attitudes Towards Change (ACTA), State-Trait Anxiety Inventory, Rosenberg Self-Esteem Scale, Beck Depression Inventory, Eating Attitude Test, Bulimic Investigatory Test Edinburgh and Body Shape Questionnaire (BSQ). RESULTS: No statistically significant differences were found between both diagnostic groups regarding dissociation scores. The ACTA at baseline, specifically for patients in the contemplation stage, mediate the effect of dissociation on the psychopathological outcome. DISCUSSION: These findings suggest that dissociation might be a transdiagnostic feature related to the EDs outcome. The psychotherapeutic framework must take it into account, particularly in patients in the contemplation stage.

RESUMO

BACKGROUND: The outcomes of bariatric surgery are very irregular and mostly unpredictable. The search for variables of predictive value is encouraged to help preventing therapeutic failures. OBJECTIVE: We aimed to confirm the hypothesis that preexisting eating behaviors could predict neuroendocrine and metabolic outcomes of gastric bypass surgery in morbidly obese subjects. METHODS: Twenty-one morbidly obese patients from the Bariatric Surgery Program of our hospital were selected according to the specific inclusion and exclusion criteria for this study. The subjects filled out a validated questionnaire to quantify the "loss-of-control" (LC) dimension of food craving and provided serum samples at the onset of the study and 1 year after gastric bypass surgery. Hematological, metabolic, and hormonal variables were studied by conventional clinical tests and enzyme immunoassays and checked for correlations with LC both before and after surgery. RESULTS: Those patients that had exhibited worse eating control at the beginning of the study experienced a better metabolic response 1 year after surgery in terms of reduction of serum insulin, HOMA1-IR, HOMA2-IR, and vitamin D1; all these variables were inversely correlated with presurgical LC. Serum brain-derived neurotrophic factor (BDNF) levels showed the same tendency; in fact, BDNF significantly decreased only in those patients with worse eating control. CONCLUSIONS: Problematic eating behaviors may predict a better response of insulin resistance and a specific reduction of serum BDNF in morbidly obese patients after gastric bypass surgery.

RESUMO

INTRODUCTION: Pathological confidence in one's thoughts is a key mechanism of chronic paranoid thinking. For this reason, many of the current therapies focus on trying to reduce it. In fact, the way some antipsychotics (e.g., haloperidol) work seems to be through the induction of doubt. Because of the impact of these pathological thoughts on positive health, studying the well-being of people who experience paranoid thoughts is fundamental. The first objective of this research is to apply the Complete State Model of Health (CSMH) to a sample of patients characterized by the presence of paranoid thinking. Our second objective is to evaluate the impact of therapies based on reducing pathological confidence on patients' well-being. METHODS: Sixty participants with SCID-5 confirmed DSM-5 diagnosis related with paranoid thinking and without mood symptoms were recruited. In order to test the existence of a two continua model of mental health (CSMH), we conducted a parallel analysis and an exploratory factor analysis. To test our hypothesis regarding the partially mediating role of doubt between paranoid thinking and patients' well-being, we conducted a biased corrected bootstrapping procedure. RESULTS: As expected, two different unipolar dimensions emerged from the measures used to assess paranoid thinking and positive health (two continua model of mental health). When patients received metacognitive and pharmacological treatment, more paranoid thinking led to more doubt in all thoughts, which in turn affected well-being. The analyses carried out confirmed the partial mediating role of doubt. CONCLUSION: Despite the efficacy shown by both metacognitive therapies and antipsychotics, it seems that they not only reduce pathological confidence, but can also affect other thoughts not linked to delirium. This effect of generalization of doubt in all thoughts negatively affected patients' well-being and quality of life.

RESUMO

(1) Background: To evaluate women's satisfaction with the care received during childbirth undergoing labour and how this changes over time. (2) Methods: An observational, multicentre and longitudinal study in two public hospitals of Spain with a convenience sample of 248 women during the post-partum period. Satisfaction was evaluated using the Intrapartal-Specific Quality from the Patient's Perspective questionnaire. Socio-demographic and clinical variables were considered. A bivariate analysis evaluated the relationship between satisfaction and the recorded variables to compare the hypotheses, and also to know if there were any significant differences between the scores obtained at the various evaluated time points (three days, 15 days, one year postpartum). The multivariate analysis by binary logistic regression helped complete the study about the variables related to the level of satisfaction; (3) Results: The mean scores for satisfaction at each time point were high, and they lowered with time. The bivariate analysis showed an association between satisfaction and the following variables: 'mother's place of birth', 'level of education', 'type of labour onset', 'type of birth' and 'type of perineal trauma'. For the multivariate analysis, women who gave birth vaginally, began labour spontaneously and had an epidural were more satisfied than those who did not; (4) Conclusions: Women seemed to obtain good levels of satisfaction with the care they received. Even so, based on continuously improved quality, we proposed some improvement measures, particularly regarding the physical environment and the information offered to patients. It is important to know at what time experience while giving birth should be evaluated as scores can lower with time as part of its normal evolution.

RESUMO

BACKGROUND: The current therapeutics of morbid obesity could be significantly improved after the identification of novel biomarkers associated with the food addiction endophenotype of obesity and with bariatric surgery outcomes. METHODS: We applied differential expression proteomics and enzyme-linked immunosorbent confirmatory assays to identify (a) proteins that varied according to loss of control over eating in morbidly obese patients and (b) proteins that varied between normoweight controls and patients before and 1 year after bariatric surgery. RESULTS: Clusterin was the only protein that consistently varied according to eating control in patients. Patients showed increased levels of serum amyloid P protein, apolipoprotein A4, serotransferrin, complement factors B and C3 and haptoglobin with respect to controls; the levels of all these proteins tended to return to control values 1 year after surgery. In contrast, apolipoprotein A1 and transthyretin were initially downregulated in patients and were scarcely changed by surgery. Leucine-rich alpha-2-glycoprotein was markedly increased in patients only after surgery. CONCLUSIONS: Clusterin could be of interest as a putative biomarker for food addiction diagnosis in people with morbid obesity. In addition, postsurgical normalization of the proteins initially dysregulated in obese subjects might help monitor clinical improvements after surgery, while lasting or newly detected alterations (i.e., those affecting transthyretin and leucine-rich alpha-2-glycoprotein) could reflect partial refractoriness and/or contribute to the early prediction of clinical problems.

RESUMO

Autism spectrum disorder diagnosis is currently based on clinical observations and behavioral evaluations exclusively, without any biological determination. Molecular biomarkers are usually obtained from biological fluids, such as blood or urine, generally through invasive and uncomfortable procedures. Patients with autism are characterized by sensory reactivity and behavioral difficulties which make sample collection problematic. Saliva has emerged as a feasible alternative to obtain relevant biological information and is especially indicated in the case of children with autism due to its painless and noninvasive sampling characteristics. Furthermore, saliva represents a valuable resource to study candidate biomarkers of autism. This has resulted in a number of interesting studies reported during the last 5 years that we have gathered and briefly discussed.

RESUMO

OBJECTIVE: Clinical research on cortisol response to stress in patients with eating disorders has provided controversial and even contradictory results. As this might be the consequence of the inclusion in the studies of heterogeneous clinical populations, 3 highly selected samples were studied. METHODS: Dexamethasone suppression test was performed on 15 restricting anorexia nervosa patients without history of bulimia nervosa (BN), 17 BN patients with normal weight and no history of anorexia nervosa, and 22 healthy controls. Three days later, the Trier Social Stress Test was applied, and 8 saliva samples were collected along the trial for cortisol assessment. RESULTS: When the patients were considered as a single group, a slightly blunted cortisol response to stress was observed, but when the 3 groups were considered separately, the blunted response was observed only in the BN patients. DISCUSSION: The results support the association between blunted cortisol response and bulimic features.

RESUMO

OBJECTIVE: translate the questionnaire Quality from the Patient's Perspective-Intrapartal (QPP-I) into Spanish, carrying out a cross-cultural adaptation and validation of its validity and reliability DESIGN: observational multi-centre transversal study, with transcultural adaptation and validation of a scale. SETTING: the study was carried out in two public Spanish hospitals. PARTICIPANTS: 248 women in their postpartum period. METHODS: the instrument was translated and back translated. Validity was determined in different ways: by comparing the QPP-I with an instrument which had already been validated (the COMFORTS scale); by carrying out an exploratory factor analysis by means of a principal component analysis (PCA), and by studying the relationship between the QPP-I and sociodemographic variables (level of studies, age, place of birth of the mother), clinical variables (number of children, type of childbirth, use of epidural, gestational age), positive feelings (control, pride, safety, being paid attention to) and negative feelings (failure, feeling ignored) experienced during childbirth, as well as physical and mental state as assessed by the woman. Reliability was estimated from the internal consistency, with the Cronbach's alpha (α), and the test-retest, with the intraclass correlation coefficient (ICC). FINDINGS: eleven factors obtained an eigenvalue greater than the unit value in the PCA, explaining 70.5% of the total variance. A statistically significant association was found with the variables place of birth of the mother, level of studies, type of birth, positive and negative feelings during childbirth, and state of health of the mother. On comparing the QPP-I with the COMFORTS scale, the area under the received operating characteristic (ROC) curve was 0.824 (confidence interval of 95%, 0.764-0.884). For the total scale, the value of α was 0.96. The consistency ICC was 0.76 (CI 95%, 0.65-0.84) and the absolute agreement ICC was 0.76 (CI 95%, 0.66-0.84). KEY CONCLUSIONS: the QPP-I with 39 items distributed among 11 factors seems adequate to measure women's satisfaction with the care received during childbirth in our setting. IMPLICATIONS FOR PRACTICE: this tool can be used in both a clinical and a research setting for women to be able to evaluate the care they receive when they give birth. It is therefore a way of improving the care given to these users.

RESUMO

Background/Objective: The evidence on efficacy of cognitive-behavioral interventions in Eating Disorders (ED) still shows inconclusive results with respect to the role of purging behaviors, more so in uncontrolled situations. Evolution of ED patients with and without purging behavior was studied 30 months after start of a multicomponent treatment. Method: 162 women (87 purging, 75 non-purging) treated in outpatient or hospitals+outpatient care units in Spain participated. The evaluation instruments were: BSQ, EAT-40, EDI, STAI, BDI and BITE. Results: At the beginning of the treatment, participants with purging behavior showed higher bulimic symptomatology, more body dissatisfaction, drive for thinness, perfectionism and ineffectiveness, anxiety and depressive symptomatology. After thirty months, intervention produced improvement in ED characteristics, emotional alterations and personal development variables, in both groups, but less in patients with no purging behavior. The effect of intervention was stronger in purging patients and variables with larger effect size: body dissatisfaction, bulimic symptomatology and anxiety. Conclusions: Purging behaviors must be considered in the design of these treatments with a view to prognosis (AU)


La evidencia sobre la eficacia de intervenciones cognitivo-conductuales en los Trastornos de la Conducta Alimentaria (TCA) aún presenta resultados no concluyentes respecto al papel que desempeñan en las conductas purgativas, más aún cuando se realizan en situaciones no controladas. Se pretende conocer la evolución tras un tratamiento multicomponente en pacientes con TCA, con presencia o ausencia de conductas purgativas, después de 30 meses del inicio del tratamiento. Método: Participaron 162 mujeres (87 purgativas y 75 no purgativas), tratadas en régimen ambulatorio o hospitalario+ambulatorio, en España. Los instrumentos de evaluación fueron: BSQ, EAT-40, EDI, STAI, BDI y BITE. Resultados: Al inicio del tratamiento, las participantes con conductas purgativas presentaban mayor sintomatología bulímica, más insatisfacción corporal, obsesión por la delgadez, perfeccionismo e ineficacia, ansiedad y sintomatología depresiva. Tras 30 meses, en ambos grupos, la intervención produjo mejoría en las características de TCA, alteraciones emocionales y variables de desarrollo personal, siendo menor en las pacientes sin conductas purgativas. El efecto de la intervención fue mayor en las participantes purgativas y las variables con mayor tamaño de efecto: insatisfacción corporal, sintomatología bulímica y ansiedad. Conclusiones: Es importante considerar las conductas purgativas en el diseño de estos tratamientos de cara al pronóstico (AU)

RESUMO

Background/Objective: The evidence on efficacy of cognitive-behavioral interventions in Eating Disorders (ED) still shows inconclusive results with respect to the role of purging behaviors, more so in uncontrolled situations. Evolution of ED patients with and without purging behavior was studied 30 months after start of a multicomponent treatment. Method: 162 women (87 purging, 75 non-purging) treated in outpatient or hospitals + outpatient care units in Spain participated. The evaluation instruments were: BSQ, EAT-40, EDI, STAI, BDI and BITE. Results: At the beginning of the treatment, participants with purging behavior showed higher bulimic symptomatology, more body dissatisfaction, drive for thinness, perfectionism and ineffectiveness, anxiety and depressive symptomatology. After thirty months, intervention produced improvement in ED characteristics, emotional alterations and personal development variables, in both groups, but less in patients with no purging behavior. The effect of intervention was stronger in purging patients and variables with larger effect size: body dissatisfaction, bulimic symptomatology and anxiety. Conclusions: Purging behaviors must be considered in the design of these treatments with a view to prognosis.


ANTECEDENTES/OBJETIVO: La evidencia sobre la eficacia de intervenciones cognitivo-conductuales en los Trastornos de la Conducta Alimentaria (TCA) aún presenta resultados no concluyentes respecto al papel que desempeñan en las conductas purgativas, más aún cuando se realizan en situaciones no controladas. Se pretende conocer la evolución tras un tratamiento multicomponente en pacientes con TCA, con presencia o ausencia de conductas purgativas, después de 30 meses del inicio del tratamiento. MÉTODO: Participaron 162 mujeres (87 purgativas y 75 no purgativas), tratadas en régimen ambulatorio o hospitalario + ambulatorio, en España. Los instrumentos de evaluación fueron: BSQ, EAT-40, EDI, STAI, BDI y BITE. RESULTADOS: Al inicio del tratamiento, las participantes con conductas purgativas presentaban mayor sintomatología bulímica, más insatisfacción corporal, obsesión por la delgadez, perfeccionismo e ineficacia, ansiedad y sintomatología depresiva. Tras 30 meses, en ambos grupos, la intervención produjo mejoría en las características de TCA, alteraciones emocionales y variables de desarrollo personal, siendo menor en las pacientes sin conductas purgativas. El efecto de la intervención fue mayor en las participantes purgativas y las variables con mayor tamaño de efecto: insatisfacción corporal, sintomatología bulímica y ansiedad. CONCLUSIONES: Es importante considerar las conductas purgativas en el diseño de estos tratamientos de cara al pronóstico.

RESUMO

Resumen: Objetivo: Identificar la posible influencia de los «estilos de la crianza¼ con la «actitud hacia el cambio¼ en pacientes diagnosticadas de trastorno de la conducta alimentaria según criterios DSM-IV-TR (American Psychiatric Association -APA-, 1994). Método: Fueron incluidas 166 pacientes de las cuales 66 (39.8%) recibieron el diagnóstico de bulimia nerviosa, 49 (29.5%) de anorexia nerviosa y 51 (30.7%) de trastorno de la conducta alimentaria no especificado. Todas las pacientes completaron una batería de cuestionarios para evaluar las relaciones familiares (APGAR familiar), los recuerdos de su crianza y su actitud hacia el cambio (ACTA) al año de seguimiento. Resultados: En el análisis de regresión múltiple realizado, se observó que la «sobreprotección¼ percibida en la infancia se relacionaba con mayores puntuaciones en «precontemplación¼ y menores puntuaciones en «acción¼ y «mantenimiento¼ . Por otra parte, el «rechazo¼ percibido en la crianza se relacionaba con puntuaciones más elevadas en «precontemplación ¼, independientemente del grado de disfunción familiar existente. Por último, el «afecto¼ percibido se relacionaba directamente con puntuaciones superiores en la fase de «acción¼ . Conclusiones: Estos resultados nos muestran la importancia de la crianza en aspectos tan relevantes del tratamiento como la motivación ante el cambio.


Abstract: Objective: To evaluate the relationships between "parental rearing styles" and "attitude towards change" in eating disorders patients according to DSM-IV-TR (American Psychiatric Association -APA-, 1994). Methods: A total of 166 patients was evaluated: 66 (39.8%) patients met criteria for bulimia nervosa, 49 (29.5%) patients met criteria for anorexia nervosa and 51 (30.7%) patients met criteria for an eating disorder not otherwise specified. All the patients completed a set of self-administered questionnaires to evaluate their family relationships (APGAR familiar), their memories of parental upbringing and their attitudes towards change (ACTA) after one year treatment. Results: A multiple regression analysis was performed. "overprotection " perceived during childhood was related to higher scores in "pre-contemplation " and lower scores in "action " and "maintenance ". On the other hand, "rejection " during upbringing was related to higher scores in "pre-contemplation " at one year follow-up regardless of family dysfunction. Finally, "warm " perceived was related to higher scores in "action" . Conclusions: These results show the relevance of breeding in treatment important aspects in eating disorders patients.

RESUMO

The objectives of the authors in this study were two-fold: (1) to explore the role of resilience in recovery from eating disorders (EDs), and (2) to develop a model of resilience in women with EDs. Semi-structured interviews with ten women were conducted in April 2011, along with two focus groups with women who had recovered from EDs (n  = 5 women each; conducted in April 2012 at the University of Deusto, Spain), one focus group with clinical experts (n = 8; conducted in April 2012 at the Foundation Against EDs of Biskay, Spain), and six narratives from primary caregivers of ED patients living in Biskay, Spain (conducted in November 2012). All data were analyzed using a grounded theory approach. All female participants acknowledged experiencing resilience in their recovery. The analysis resulted in a conceptual model of resilience composed of the following categories: deep dissatisfaction with life, turning point, acceptance, hope, determination to change, accountability for the ED, active coping, getting social support, gaining self-knowledge, getting information about EDs, increase well-being, trait resilience, initiating new projects and living in the here and now. According to the model presented, resilience preceded the experience of recovery in women with EDs in this sample and could be a useful asset for future interventions.
