Eating Disorders最新文献

Community evidence indicates high eating disorder (ED) and comorbid symptom severity among LGBTQ+ compared to cisgender heterosexual (CH) individuals. Little is known about such disparities in ED treatment samples, especially in outpatient treatment. We aimed to descriptively characterize and investigate baseline group differences in symptom severity between LGBTQ+ and CH ED outpatients at treatment intake. Data from 60 (22.3%) LGBTQ+ and 209 (77.7%) CH ED outpatients were used to examine: (1) demographic and diagnostic differences; (2) differences in ED, depressive, and emotion dysregulation symptoms. Objectives were tested using Fisher-Freeman-Halton exact and independent samples t-tests, and analyses of covariance adjusted for age and diagnosis, respectively. Most LGBTQ+ outpatients were bisexual (55.2%), and 6.5% identified as transgender and non-binary. LGBTQ+ outpatients presented to treatment at younger ages (Mean Difference [MD] = -3.39, p = .016) and reported more severe depressive symptoms (MD = 5.73, p = .004) than CH patients, but endorsed similar ED symptom and emotion dysregulation severity. Groups did not differ in other demographic or diagnostic characteristics. LGBTQ+ individuals may develop more severe depression and similarly severe EDs at earlier ages but seek outpatient care sooner than CH peers. Managing depressive symptoms may be particularly important for LGBTQ+ ED patients.

The current study assessed treatment outcome for 99 adult admissions to a residential program specifically designed for binge eating spectrum disorders (BESD). Participants completed self-report measures at admission, discharge, and 12-month follow-up and were asked to complete blood draws at admission and follow-up. Primary outcomes were eating behaviors; secondary outcomes included comorbid symptoms and physiological variables. Eating behaviors improved significantly from admission to follow-up, as did most comorbid symptoms and quality of life, despite no change in body mass index. Some variables displayed a curvilinear relationship, with some worsening of symptoms from discharge to follow-up, although scores at follow-up remained well below admission values. Participation in the treatment program was associated with reduced problematic eating and comorbid symptoms and increased quality of life up to one year after discharge. Findings from this study may encourage the development of similar residential treatment programs for BESD for those who have not responded to outpatient care or mixed milieu settings, and may prompt randomized studies testing similar treatments versus usual care.

This study examined the effect of pre-treatment levels of parental expressed emotion (EE) on early treatment response for adolescent anorexia nervosa (AN). Data were collected from 121 adolescents, ages 12-18, who met DSM-IV criteria for AN excluding the amenorrhea criterion, and their parents. Participants were randomized to family-based treatment (FBT) or adolescent-focused therapy (AFT). To examine the effects of different thresholds of EE, we used two different levels of EE in analyses. Results demonstrated that adolescents who had at least one parent with elevated EE indicated by a lower threshold (i.e. even mild levels) at baseline were less likely to achieve an early treatment response, suggesting that EE might interfere with treatment success from the start of treatment. When high EE was defined by a higher threshold, these effects were no longer significant, regardless of treatment type (FBT or AFT). These findings suggest that adolescents with AN may be more sensitive to EE than other mental illnesses, such that lower thresholds of EE impact the speed with which they are able to reduce symptoms and gain weight in treatment. It may be necessary to target parental EE prior to or early in treatment or pivot to parent-focused treatment to change the trajectory of treatment response. Future research is needed to explore ways parental EE can be reduced.

Eating disorders (EDs) are associated with emotion regulation difficulties. However, most studies have examined intrapersonal emotion regulation difficulties and strategies without consideration of interpersonal emotion regulation (IER). Thus, it remains unknown whether intrinsic IER (i.e., how people regulate their emotions through others) is associated with disordered eating. The present study examined whether putatively maladaptive IER strategies such as reassurance seeking and venting were associated with ED cognitions, behaviors, and symptom severity. Additionally, we examined whether IER strategy use varied as a function of probable ED diagnosis. A sample of 181 college students (M_age = 20.01 years, SD = 2.18) from a large northeastern university completed self-report measures of disordered eating, IER strategies, and intrapersonal emotion regulation difficulties. As predicted, reassurance seeking was associated with most ED symptomatology and ED symptom severity except for fasting frequency. Venting was only associated with body dissatisfaction. Associations between reassurance seeking and ED symptom severity and excessive exercise frequency remained significant even after controlling for sex and intrapersonal emotion regulation strategies. Finally, participants with a probable ED diagnosis reported greater reassurance seeking but not venting compared to nonprobable ED cases. These findings highlight the important associations between IER strategy use and disordered eating, namely, reassurance seeking. Additional research is needed to examine the associations between IER strategy use and disordered eating longitudinally.

Non-purging compensatory behaviors (NPCB; e.g. driven exercise, fasting, other extreme behaviors) are a subcategory of compensatory behaviors typically characterized as infrequent and less severe. Limited prior research has studied NPCB despite their increasing prevalence among adults with binge-spectrum eating disorders (B-ED). More research is needed to understand the types of NPCB present among B-ED and the association between NPCB, clinical severity, and treatment outcomes. Secondary analyses were conducted among 155 adults with B-ED in cognitive-behavioral (CBT)-based clinical trials. At baseline and post-treatment, clinical interviews of eating pathology assessed binge eating frequency, purging compensatory behavior frequency, and global eating pathology. The following NPCB were also assessed: driven exercise, 24-h fasting, 8+ waking hours of compensatory fasting, chewing and spitting, and other extreme weight control behaviors. Participants engaging in NPCB reported higher global eating pathology than those not engaging in NPCB. Frequency of chewing and spitting and 24-h fasting significantly decreased over treatment. Engagement in NPCB at baseline did not predict CBT outcomes. The current study highlights the prevalence and clinical severity of NPCB in B-ED but offers promising results regarding the potential for CBT to improve these behaviors. More research is needed on other extreme weight control behaviors reported qualitatively in our sample and on the maintenance of improvements in non-purging behaviors after CBT.
