RESUMEN
BACKGROUND: Eating disorders (EDs), such as (atypical) Anorexia (AN) and Bulimia Nervosa (BN), are difficult to treat, causing socioeconomic impediments. Although enhanced cognitive behavioral therapy (CBT-E) is widely considered clinically effective, it may not be the most beneficial treatment for (atypical) AN and BN patients who do not show a rapid response after the first 4 weeks (8 sessions) of a CBT-E treatment. Alternatively, group schema therapy (GST) may be a valuable treatment for this ED population. Even though GST for EDs has yielded promising preliminary findings, the current body of evidence requires expansion. On top of that, data on cost-effectiveness is lacking. In light of these gaps, we aim to describe a protocol to examine whether GST is more (1) clinically effective and (2) cost-effective than CBT-E for (atypical) AN and BN patients, who do not show a rapid response after the first 4 weeks of treatment. Additionally, we will conduct (3) process evaluations for both treatments. METHODS: Using a multicenter RCT design, 232 Dutch (atypical) AN and BN patients with a CBT-E referral will be recruited from five treatment centers. Clinical effectiveness and cost-effectiveness will be measured before treatment, directly after treatment, at 6 and at 12 months follow-up. In order to rate process evaluation, patient experiences and the degree to which treatments are implemented according to protocol will be measured. In order to assess the quality of life and the achievement of personalized goals, interviews will be conducted at the end of treatment. Data will be analyzed, using a regression-based approach to mixed modelling, multivariate sensitivity analyses and coding trees for qualitative data. We hypothesize GST to be superior to CBT-E in terms of clinical effectiveness and cost-effectiveness for patients who do not show a rapid response to the first 4 weeks of a CBT-E treatment. DISCUSSION: To our knowledge, this is the first study protocol describing a multicenter RCT to explore the three aforementioned objectives. Related risks in performing the study protocol have been outlined. The expected findings may serve as a guide for healthcare stakeholders to optimize ED care trajectories. TRIAL REGISTRATION: clinicaltrials.gov (NCT05812950).

OBJECTIVE: Gastrointestinal symptoms, particularly postprandial fullness, are frequently reported in eating disorders. Limited data exist evaluating how these symptoms change in response to outpatient psychological treatment. The current study sought to describe the course of postprandial fullness and early satiation across psychological treatment for adults with bulimia nervosa and related other specified feeding or eating disorders and to test if anxiety moderates treatment response. METHODS: Secondary data analysis was conducted on questionnaire data provided by 30 individuals (80% white, M(SD)age = 31.43(13.44) years; 90% female) throughout treatment and six-month follow-up in a pilot trial comparing mindfulness and acceptance-based treatment with cognitive-behavioral therapy for bulimia nervosa. Participants completed items from the Rome IV Diagnostic Questionnaire for Adult Functional Gastrointestinal Disorders and the State Trait Anxiety Inventory. RESULTS: Postprandial fullness and early satiation both significantly decreased over time (ds = 1.23-1.54; p's < .001). Baseline trait anxiety moderated this outcome, such that greater decreases were observed for those with higher baseline anxiety (p = .02). DISCUSSION: Results extend prior work in inpatient samples by providing preliminary data that postprandial fullness and early satiation decrease with outpatient psychological treatment for bulimia nervosa. Baseline anxiety moderated this effect for postprandial fullness. Future work should replicate findings in a larger sample and test anxiety as a mechanism underlying postprandial fullness in eating disorders. PUBLIC SIGNIFICANCE: The current study found that common gastrointestinal symptoms (postprandial fullness and early satiation) decrease over the course of outpatient psychotherapy for adults with full and subthreshold bulimia nervosa. Postprandial fullness decreased more across time for those high in anxiety.

BACKGROUND: The current review broadly summarises the evidence base for pharmacotherapies and adjunctive and alternative therapies in the treatment of eating disorders and disordered eating. METHODS: This paper forms part of a Rapid Review series examining the evidence base in the field of eating disorders. This was conducted to inform the Australian National Eating Disorder Research and Translation Strategy 2021-2030. ScienceDirect, PubMed and Ovid/Medline were searched for included studies published between 2009 and 2021 in English. High-level evidence such as meta-analyses, large population studies and randomised control trials were prioritised, and grey literature excluded. Data from included studies relating to pharmacotherapy, and to adjunctive and alternative therapies in eating disorders, were synthesised and disseminated in the current review. RESULTS: A total of 121 studies were identified, relating to pharmacotherapy (n = 90), adjunctive therapies (n = 21) and alternative therapies (n = 22). Some of the identified studies involved combinations of the above (e.g. adjunctive pharmacotherapy). Evidence of efficacy of interventions across all three categories was very limited with few relevant high quality clinical trials. There was a particular scarcity of evidence around effective treatments for anorexia nervosa (AN). With treatment of bulimia nervosa (BN), fluoxetine has exhibited some efficacy leading to regulatory approval in some countries. With binge eating disorder (BED), recent evidence supports the use of lisdexamfetamine. Neurostimulation interventions show some emerging efficacy in the treatment of AN, BN and BED but some, such as deep brain stimulation can be highly invasive. CONCLUSION: Despite widespread use of medications, this Rapid Review has identified a lack of effective medications and adjunctive and alternative therapies in the treatment of EDs. An intensification of high-quality clinical trial activity and drug discovery innovation are required to better assist patients suffering from EDs.
Eating disorders have the highest mortality rates and treatment costs of all mental health conditions. This rapid review summarises the evidence around the use of medications and various alternative therapies in the treatment of eating disorders. The review highlights a lack of effective interventions for the treatment of anorexia nervosa with an urgent need to trial new treatments for this condition. Two medications show some efficacy in treating other eating disorders: the antidepressant drug fluoxetine for the treatment of bulimia nervosa, and the stimulant drug lisdexamfetamine for binge eating disorder. There is some positive evidence emerging from novel therapies that involve brain stimulation technologies. Overall, more high-quality research is needed to discover and develop new medications, and other alternative therapies, to better assist patients with eating disorders.
RESUMEN
This study explores the religious and spiritual aspects of eating disorder recovery and the role of social media in the context of a third sector community-based recovery group in the UK. Four online focus groups explored participant perspectives (17 participants in total) using thematic analysis. The qualitative findings highlight that relational support from God is important in eating disorder recovery and coping, although this can be challenged by spiritual struggles and tensions. Relational support from people is also relevant where it offers a place to share different experiences together giving a sense of community belonging. Social media was also found to be important in relation to eating disorders, either providing a community of support or exacerbating existing issues. This study suggests that the role of religion and social media should be acknowledged where it is important for that individual in relation to eating disorder recovery.

Objective: The classification of anorexia nervosa (AN) into subtypes is relevant due to their different symptomatology. However, subtypes (restricting type: AN-R; purging type: AN-P) differ also in terms of their personality functioning. Knowledge about these differences would allow for better treatment stratification. A pilot study indicated differences in structural abilities that can be assessed by the operationalized psychodynamic diagnosis (OPD) system. The aim of this study was therefore to systematically explore differences in personality functioning and personality between the two AN subtypes and bulimia nervosa (BN) using three personality (functioning) constructs. Methods: A total of N = 110 inpatients with AN-R (n = 28), AN-P (n = 40), or BN (n = 42) were recruited in three clinics for psychosomatic medicine. Assignment to the three groups was performed using a comprehensive questionnaire validated for diagnostic purposes (Munich-ED-Quest). Personality functioning was examined using OPD Structure Questionnaire (OPD-SQ), personality by using the Personality Inventory for DSM-5-Brief Form and Big Five Inventory-10. (M)ANOVAs were used to examine differences across eating disorder groups. In addition, correlation and regression analyses were conducted. Results: We observed differences on several sub- and main scales of the OPD-SQ. Whereas patients with BN showed the lowest levels, AN-R patients displayed the highest levels of personality functioning. On some sub- and main scales, such as "affect tolerance," the subtypes of AN differed from BN, whereas on the scale "affect differentiation," AN-R, differed from the other two groups. The total eating disorder pathology score of the Munich-ED-Quest best predicted overall personality structure [stand. ß = 0.650; t(104) = 6.666; p < 0.001] and self-regulation [stand. ß = 0.449; t(104) = 3.628; p < 0.001]. Discussion: Our findings confirm most of the results of the pilot study. These findings can facilitate the development of stratified treatment approaches for eating disorders.
RESUMEN
AIM: To assess the effect of visual art- and music-based interventions in the treatment of eating disorders. METHODS: This study was registered in PROSPERO (CRD42020161503). Six databases (CINAHL, EMBASE, Lilacs, PsycINFO, PubMed and The Cochrane Library) were consulted. The searches were performed on 19 June 2019, and updated on 18 March 2022. No restriction on language, date, or publication status was applied. Methodological quality was assessed using Joanna Briggs Institute's instruments. All steps were performed by two independent reviewers and a third participated in the event of disagreement. RESULTS: Eight studies were included. Few statistically significant results were found. Overall, both interventions might help to reduce negative emotional states. CONCLUSION: Visual art- and music-based interventions present limited and inconclusive scientific evidence in patients with eating disorders and therefore their effectiveness is currently unknown. A theoretical model is proposed to guide future research. Further studies are needed to clarify their clinical relevance.
RESUMEN
Eating disorders (EDs) are a non-heterogeneous group of illnesses with significant physical and mental comorbidity and mortality associated with maladaptive coping. With the exception of lisdexamfetamine (Vyvanse) for binge eating disorder, no medications have been effective for the core symptoms of ED. ED requires a multimodal approach. Complementary and integrative medicine (CIM) can be helpful as an adjunct. The most promising CIM interventions are traditional yoga, virtual reality, eye movement desensitization and reprocessing, Music Therapy, and biofeedback/neurofeedback.

OBJECTIVE: Binge-eating disorder (BED) and bulimia nervosa (BN) are characterised by binge eating. Changing unwanted behaviour is difficult, as intentions do not automatically lead to action. Implementation intentions (IIs) may help bridging the gap between intentions and behaviour. IIs are 'if-then' plans promoting goal attainment. Effects are moderated by degree of plan formation. Using mental imagery (MI) to impress IIs may strengthen plan formation and goal attainment. METHOD: In a students' sample with subjective binge eating, we compared IIs without MI, IIs with MI, and a control condition regarding their ability to reduce binge eating. Participants received three II-sessions and kept food diaries for 4 weeks. RESULTS: Results showed a significant and medium to large reduction of binge eating in both II-conditions compared to the control condition, that was sustained for 6 months. No additional effects of MI were found. CONCLUSIONS: Applying IIs results in long-lasting reductions in subjective binge eating. The absence of additional effects of MI may be due to floor effects. Also, participants in the IIs without MI condition may have applied MI without being instructed to do so. In future research, ideally with a clinical sample, it is recommended to prevent or control for this.

OBJECTIVES: Bulimia nervosa (BN) is a common psychiatric disorder among adolescent girls with potentially significant complications. Family relationships play a major role in the development and progression of this disorder. Studies in migrant populations suffering from eating disorders show contrasting results depending on the generation of migrants: first generation migrants have fewer eating disorders than the native population, while the prevalence of this disorder is more important than the latter among second and third generation migrants. In our clinical experience, we have frequently encountered so-called "mixed" families, which are families composed of one migrant parent and one non-migrant parent. Research focusing on this kind of family is scarce which is why we chose to explore their dynamic. METHODS: This study explored the issues around food and family relationships of adolescent girls suffering from BN, a topic that, to date, has not yet been studied. Ten interviews were conducted with five adolescent girls with BN between the ages of 16 and 20 and their parents, using photo-elicitation to enrich the collected data. RESULTS: The results were organized around two axes: (1) identity issues around food, that is the assimilation process described by both parents and adolescents concerning family meals and food habits, and how the adolescents struggle to manage this interbreeding; and (2) transmission issues with the consequences the migrant parent has to deal with to transmit his/her cultural identity with food while being far away from the homeland, and the difficulties between this parent and his/her child to share this heritage. Both issues, identity and transmission, appear to be central among these families. CONCLUSIONS: Our results suggest a difficulty in mentalizing identity issues in adolescent girls; the function of appeasement around non-mentalized tensions was highlighted. In our opinion, in this particular context, BN acts as a means of expressing the difficulty of their mixed culture. This enables it to draw some clinical implications, especially using mentalization-based therapy which has already shown efficacy in adolescents with borderline personality disorder and ED.

BACKGROUND: Lower bone mineral density (BMD) increases the risk of osteoporosis in individuals with eating disorders (EDs), particularly women with anorexia nervosa (AN), making them susceptible to pain and fractures throughout adulthood. In AN, low weight, hypothalamic amenorrhoea, and longer illness duration are established risk factors for low BMD, and in people with other EDs a history of AN seems to be an important risk factor for low BMD. PURPOSE: To conduct a systematic review and meta-analysis of BMD in individuals with EDs, including AN, bulimia nervosa (BN), binge-eating disorder (BED) and other specified feeding or eating disorders (OSFED) compared to healthy controls (HC). METHODS: Following PRISMA guidelines, electronic databases were reviewed and supplemented with a literature search until 2/2022 of publications measuring BMD (dual-energy X-ray absorptiometry or dual photon absorptiometry) in females with any current ED diagnosis and a HC group. Primary outcomes were spine, hip, femur and total body BMD. Explanatory variables were fat mass, lean mass and ED clinical characteristics (age, illness duration, body mass index (BMI), amenorrhoea occurrence and duration, and oral contraceptives use). RESULTS: Forty-three studies were identified (N = 4163 women, mean age 23.4 years, min: 14.0, max: 37.4). No study with individuals with BED met the inclusion criteria. BMD in individuals with AN (total body, spine, hip, and femur), with BN (total body and spine) and with OSFED (spine) was lower than in HC. Meta-regression analyses of women with any ED (AN, BN or OSFED) (N = 2058) showed low BMI, low fat mass, low lean mass and being amenorrhoeic significantly associated with lower total body and spine BMD. In AN, only low fat mass was significantly associated with low total body BMD. CONCLUSION: Predictors of low BMD were low BMI, low fat mass, low lean mass and amenorrhoea, but not age or illness duration. In people with EDs, body composition measurement and menstrual status, in addition to BMI, are likely to provide a more accurate assessment of individual risk to low BMD and osteoporosis.
Individuals with eating disorders (EDs) have an increased risk for developing osteoporosis and suffering fractures. To better understand this problem, we conducted a systematic review and meta-analysis comparing bone mineral density (BMD) of females with EDs with that of healthy people without an ED. We also tried to identify key factors linked with reduced bone mass in EDs. We included studies reporting BMD of individuals with anorexia nervosa (AN), bulimia nervosa (BN), binge-eating (BED) or other non-specified ED (OSFED), and of healthy controls. We found that people with AN had overall lower BMD than controls and also in the spine, hip, and femur. In people with BN, there was lower BMD overall and in the spine, but that must be only in those who previously had AN. In people with OSFED, BMD was lower in the spine. Having a low BMI, low fat mass, low lean mass and not having menstrual periods seem to negatively affect BMD. Therefore, this systematic review supports the idea that people with current or past AN, irrespective of their current ED diagnosis, should have their bone health assessed. For early identification of those most at risk, body composition measurements, current menstrual status, duration of amenorrhoea and presence or absence of a history of AN should be considered in clinical practice.
RESUMEN
Compulsive exercise is linked with poorer treatment outcomes in people with eating disorder (EDs). High-performance athletes represent a growing and complex subcomponent of the broader ED population, and emergent evidence indicates that different conceptualisations of compulsive exercise are needed in this population. Existing randomised controlled trials in ED populations have demonstrated small treatment effects on compulsive exercise compared with control groups; however, athletes were sparsely sampled across these studies. Thus, the extent to which current treatments for compulsive exercise in EDs are also effective in high-performance athletes is unknown. For this opinion paper, we sought representation from high-performance sports leadership, someone with lived experience of both an ED and high-performance athletics, and ED clinical experts. We discuss the utility of recommending exercise abstinence in ED treatment with athletes, as well as a number of other treatment strategies with some evidence in other contexts for further consideration and research in this population. These include using mindfulness-based interventions as an adjunct to cognitive-behavioural therapies, using wearable technologies and self-reported fatigue to inform training decisions, and incorporating greater exercise variation into training programs. We also offer practical considerations for clinicians seeking to apply foundational elements of cognitive-behavioural interventions (e.g., exposure and response prevention, cognitive restructuring, behavioural experiments) into an ED treatment program for a high-performance athlete. Future research is needed to examine characteristics of pathological compulsive exercise in athletes and whether available treatments are both feasible and effective in the treatment of compulsive exercise in athletes with an ED.
RESUMEN
Higher trait mindfulness may be protective against eating disorder (ED) pathology. However, little is understood about which specific mindfulness processes connect to specific ED symptoms. This study (Nâ¯=â¯1,056 undergraduates) used network analysis at the symptom/process level to identify: (1) central nodes, or symptoms/processes with the greatest collective connection with all other symptoms/processes; and (2) bridge nodes, or symptoms/processes driving interconnection between mindfulness processes and ED symptoms. We conducted analyses both with and without food- and body-related mindfulness items. Central nodes included: describing how one feels in detail, expressing how one feels in words, and feeling guilty about eating due to shape/weight. Bridge nodes connecting higher mindfulness processes with lower ED symptoms included: the eating disorder symptom, being uncomfortable about others seeing one eat, and the mindfulness process, not criticizing oneself for having irrational/inappropriate emotions. Bridge nodes connecting higher mindfulness processes with higher ED symptoms included: noticing sensations of the body moving when walking and noticing how food/drinks affect thoughts, bodily sensations, and emotions. Findings suggest that future research should explore whether mindfulness-based interventions for EDs may be more effective by targeting mindfulness processes related to describing, expressing, and accepting emotions, accepting discomfort when eating with others, and reducing hyper-focus on and reactivity to food-and-body related sensations.

Current treatments for binge eating disorder (BED) and bulimia nervosa (BN) only show moderate efficacy, warranting the need for novel interventions. Impairments in food-related inhibitory control contribute to BED/BN and could be targeted by food-specific inhibitory control training (ICT). The aim of this study was to establish the feasibility and acceptability of augmenting treatment for individuals with BN/BED with an ICT app (FoodT), which targets motor inhibition to food stimuli using a go/no-go paradigm. Eighty patients with BED/BN receiving psychological and/or pharmacological treatment were randomly allocated to a treatment-as-usual group (TAU; n = 40) or TAU augmented with the 5-min FoodT app daily (n = 40) for 4 weeks. This mixed-methods study assessed feasibility outcomes, effect sizes of clinical change, and acceptability using self-report measures. Pre-registered cut-offs for recruitment, retention, and adherence were met, with 100% of the targeted sample size (n = 80) recruited within 12 months, 85% of participants retained at 4 weeks, and 80% of the FoodT + TAU group completing ≤8 sessions. The reduction in binge eating did not differ between groups. However, moderate reductions in secondary outcomes (eating disorder psychopathology: SES = -0.57, 95% CI [-1.12, -0.03]; valuation of high energy-dense foods: SES = -0.61, 95% CI [-0.87, -0.05]) were found in the FoodT group compared to TAU. Furthermore, small greater reductions in food addiction (SES = -0.46, 95% CI [-1.14, 0.22]) and lack of premeditation (SES = -0.42, 95% CI [-0.77, -0.07]) were found in the FoodT group when compared to TAU. The focus groups revealed acceptability of FoodT. Participants discussed personal barriers (e.g. distractions) and suggested changes to the app (e.g. adding a meditation exercise). Augmenting treatment for BED/BN with a food-specific ICT app is feasible, acceptable, and may reduce clinical symptomatology with high reach and wide dissemination.

Eating disorders and disturbed body image have been reported in individuals with cystic fibrosis (CF) and may contribute to poor weight gain, reduced lung function and increased mortality. CF individuals often look and feel different from their peers and bear the additional burden of body-altering side effects of treatment. As a result, the impact of disorders such as binge eating, anorexia nervosa, and bulimia nervosa may adversely affect the social, emotional, and physical development of those with CF. Multiple risk factors may contribute to the development of an eating disorder in CF. Growth failure is affected by the physical impairments of CF, including pancreatic insufficiency, high energy demands, respiratory infections, and delayed and stunted growth and puberty. Psychological factors, such as CF associated depression and anxiety, intense focus on BMI, lack of control in a chronic disease, and preoccupation with morbidity and mortality, likely further contribute. Exercise inefficiency, secondary to poor lung function, low BMI and pulmonary exacerbations, and the potential for medication manipulation are also additional risk factors. The intense scrutiny around BMI may lead to a poor relationship with food, including disordered eating habits, abnormal mealtime behaviors, and stressful caregiver-patient interactions regarding meals. This further contributes to a discrepancy between ideal CF nutritional standards and the reality of the challenges of appropriate daily energy intake for an individual with CF. It is imperative that CF providers are equipped to identify potential eating disorders and disturbed body image in their CF patients. Improved screening and monitoring practices should be developed and implemented, with multidisciplinary support from all CF care team members, including dietitians, mental health professionals, and social workers, to best support holistic care and optimize outcomes. Increased attention to these concerns may help reduce CF related morbidity and mortality.
RESUMEN
BACKGROUND: This study aimed to investigate the effectiveness of mindfulness-based cognitive therapy (MBCT) as a complementary approach in patients with bulimia nervosa (BN) or binge eating disorder (BED), and to assess how the reduction of the cognitive load of words related to eating disorders (ED) could constitute an intermediate factor explaining its global efficacy. METHODS: Eighty-eight women and men participated in clinical assessments upon inscription, prior to and following 8-week group MBCT. Mindfulness skills were assessed using the five facet mindfulness questionnaire; eating behaviors were assessed using the Three Factor Eating Questionnaire (TFEQ); comorbid pathologies were assessed using the beck depression index and the state-trait anxiety inventory. The cognitive load of words associated with ED was assessed through a modified version of the Stroop color naming task. RESULTS: Mindfulness skills improved significantly (p < .05) after group MBCT. The improvement of TFEQ scores was accompanied by reduced levels of depressive mood and trait anxiety. The positive impact of MBCT on TFEQ score was directly related to an improvement of the performance in the Stroop task. CONCLUSIONS: MBCT represents an interesting complementary therapy for patients with either BN or BED, at least when cognitive and behavioral domains are concerned. Such efficacy seems to be mediated by the reduction of the cognitive load associated with ED stimuli, which offers a possible explanation of how MBCT could reduce binge-eating behaviors. Other studies are needed, in independent centers, to focus more directly on core symptoms and long-term outcome.

Approximately 1.25 million people in the UK suffer from an eating disorder, yet the treatment options show limited efficacy, warranting the need for novel approaches. This study aimed to investigate the perspectives of people with eating disorders on the use of complementary therapies and psychedelic research and treatment. Two hundred participants with eating disorders took part in this web survey study. The majority of participants (70%) had used a complementary treatment to manage their eating disorder. Participants believed that psychedelic research was worthwhile in the context of a moderate level of concern. The most popular solutions to meet these concerns included providing education around psychedelics and their effects and use in psychiatry and experiencing endorsement from professionals in the area. Moreover, participant responses emphasized the need for a safe, monitored environment and the patient-therapist rapport in the context of psychedelic treatment. The findings are explored concerning future trials of psychedelics as a treatment for eating disorders.

OBJECTIVE: Although existing research supports the efficacy of mindfulness- and acceptance-based treatments (MABTs) for eating disorders (EDs), few studies have directly compared outcomes from MABTs to standard CBT. METHOD: Participants (N = 44), treatment-seeking adults with bulimia-spectrum EDs, were screened for eligibility, consented, and randomized to receive 20 sessions of outpatient, individual CBT or MABT treatment. Treatment outcomes (binge eating and compensatory behavior episodes, global ED severity, depressive symptoms, quality of life, emotional awareness/clarity, distress tolerance, values-based decision-making, and emotion modulation) were measured at pre-treatment, post-treatment, and 6-month follow up. Data on feasibility and acceptability are also presented. RESULTS: Treatment and assessment retention rates were comparable between MABT and CBT (p range = .51-.73) and between-group differences on acceptability measures were very small (d range = 0.03-0.19). Both conditions produced notable and generally comparable changes in most treatment outcomes at post-treatment (within group d range = 0.06-1.77). DISCUSSION: The MABT and CBT conditions demonstrated comparable degrees of feasibility, acceptability, and symptom improvement, suggesting that MABTs warrant further evaluation as ED treatments.

Outcomes from cognitive behavioral therapy for binge-eating spectrum disorders are suboptimal, possibly due in part to deficits in self-regulation (i.e., the ability to control behavior in pursuit of long-term goals despite internal challenges). Mindfulness and acceptance-based treatments (MABTs) integrate behavioral treatment with psychological strategies designed to enhance self-regulation, yet little is known about how and for whom they are effective. The present study will utilize the multiphase optimization strategy to identify which of four MABT components (mindful awareness, distress tolerance, emotion modulation, values-based decision making) to include in a fully powered clinical trial. Participants (n = 256) will be randomized to 16 sessions in one of 16 conditions, each a different combination of MABT components being included or excluded from a base behavioral treatment. Our primary aim is to evaluate each component's independent efficacy on disordered eating symptoms. Our secondary aims are to confirm each component's target engagement (i.e., whether each component improves the targeted variable and outcomes), and test that each component's efficacy is moderated by baseline weaknesses in the same component (e.g., that participants with poor distress tolerance at baseline benefit most from the distress tolerance component). Our exploratory aim is to quantify the component interaction effects.

BACKGROUND: While improving emotion regulation (ER) is a central goal in the therapy of bulimia nervosa (BN), there is no experimental evidence on the efficacy of different ER strategies. (1) We hypothesized that mindfulness as well as self-compassion as contextual strategies and cognitive restructuring as classical cognitive behavioral strategy would outperform waiting in improving emotional and eating disorder related outcomes after an unpleasant mood induction. Further, we explored (2) whether contextual strategies outperformed cognitive restructuring and (3) whether comorbid mental disorders and previous treatment for BN influenced the efficacy of contextual ER strategies compared to cognitive restructuring. METHODS: Within their first 2 weeks of treatment, inpatients with BN were instructed to utilize mindfulness, self-compassion, and cognitive restructuring or to wait after a pre-induced sadness in a permuted repeated measures design. Patients further rated different emotional and cognitive outcomes on a visual analogue scale at baseline, and before and after each ER strategy. Multiple linear regression analyses were employed to compare (1) the active conditions to waiting, (2) the contextual strategies with cognitive restructuring, and (3) the latter analysis again, but separated according to comorbidity and previous treatment. RESULTS: Forty-eight female inpatients with BN (mean age = 26.44 years, SD = 6.64) completed the study. (1) Contextual ER strategies were more efficacious than waiting for eating disorder symptoms. Cognitive restructuring did not differ from waiting for any outcome. (2) Contextual strategies were more efficacious than cognitive restructuring for emotional outcomes. (3) Self-compassion was more efficacious than cognitive restructuring in patients with comorbid mental disorders and previous treatment in increasing control over the present feeling. CONCLUSIONS: Contextual strategies, especially self-compassion, seem more efficacious than waiting and cognitive restructuring in improving short-term ER in patients with BN in an experimental setting.
RESUMEN
OBJECTIVE: Mindfulness is implicated in eating disorder (ED) psychopathology. However, this literature has not been synthesized to date. The current meta-analysis examined the associations between mindfulness and ED psychopathology. METHODS: A total of 74 independent samples (effects = 576) were included. We used a multilevel random-effects model to estimate summary study-level effect sizes, and multilevel mixed-effects models to examine moderator effects. RESULTS: Mindfulness was negatively associated with ED psychopathology (r = -.25, p < .001), both concurrently (r = -.25, p < .001) and prospectively (rs = -.22 to -.24, ps < .001). Associations were strongest for binge eating, emotional/external eating, and body dissatisfaction as well as the acting with awareness and nonjudging facets. DISCUSSION: Mindfulness may be an important process in ED psychopathology. Future research should prospectively and experimentally examine the relation between mindfulness and ED psychopathology.
OBJETIVO: La atención plena (mindfulness) está implicada en la psicopatología de los trastornos de la conducta alimentaria (TCA). Sin embargo, esta literatura no ha sido sintetizada a la fecha. El presente meta-análisis examinó las asociaciones entre la atención plena y la psicopatología de los TCA. MÉTODOS: Se incluyeron un total de 74 muestras independientes (efectos = 576). Utilizamos un modelo de efectos aleatorios multinivel para estimar la síntesis de los tamaños de efecto por nivel de estudio, y los modelos de efecto mixto multinivel para examinar los efectos moderadores. RESULTADOS: La atención plena fue asociada negativamente con la psicopatología de TCA (r = −.25, p < .001), tanto concurrentemente (r = −.25, p < .001) como prospectivamente (rs = −.22-−.24, ps < .001). Las asociaciones fueron más fuertes para trastorno por atracón, alimentación emocional/externa, e insatisfacción corporal, así como también el actuar con conciencia y sin juzgar las facetas. DISCUSIÓN: La atención plena (mindfulness) puede ser un proceso importante en la psicopatología de los TCA.
