RESUMO

Binge-spectrum eating disorders (EDs; bulimia nervosa, binge eating disorder) often develop during adolescence and are associated with serious psychological and physical consequences. Current treatments for adolescents are highly behavioral in nature and while efficacious, many patients do not reach remission indicating that current treatments fail to target a key maintenance factor for EDs. One potential maintenance factor is poor family functioning (FF). In particular, high family conflict (e.g., arguing, critical comments) and low family cohesion (e.g., warmth, support) are known to maintain ED behaviors. Poor FF can (1) cause or exacerbate an adolescent's use of ED behaviors to cope with life stress and/or (2) inhibit parents from being a resource to adolescents during ED treatment. Attachment-Based Family Therapy (ABFT) is specifically designed to improve FF, and thus may be a promising adjunct to behavioral ED intervention strategies. ABFT, however, has not been tested in adolescents with binge-spectrum EDs. Thus, the current study is the first to evaluate a 16-week adapted ABFT treatment for adolescents with EDs (N = 8, Mage = 16.00, 71.43% female, 71.43% White) fusing together behavioral treatment for EDs with ABFT for highest possible impact. Eight families were treated in an open pilot trial to examine treatment feasibility, acceptability, and preliminary efficacy on FF and eating pathology. Overall, findings were promising. ABFT + B treatment was feasible and acceptable and showed preliminary evidence that it could improve FF and ED behaviors. Future research will test this intervention in a larger sample and further examine the role of FF in maintaining ED symptoms.

RESUMO

Inhibitory control, one's ability to inhibit automatic responses to desirable stimuli, may be inadequately targeted in interventions for loss-of-control eating (LOC). Promising evidence has identified inhibitory control trainings (ICTs) as an avenue to target inhibitory control directly; however, effects of ICTs on real-world behavior are limited. Compared to typical computerized trainings, virtual reality (VR) presents several potential advantages that may address key shortcomings of traditional ICTs, i.e. poor approximation to everyday life. The present study utilized a 2 × 2 factorial design of treatment type (ICT vs sham) by treatment modality (VR vs standard computer), which allows for increased statistical power by collapsing across conditions. Our primary aim was to examine the feasibility and acceptability of six weeks of daily training among groups. A secondary aim was to preliminarily assess main and interactive effects of treatment type and modality on target engagement and efficacy (i.e., training compliance, change in LOC episodes, inhibitory control, and implicit liking of foods). Participants (N = 35) with ≥1×/weekly LOC were assigned to one of four conditions and completed ICTs daily for six weeks. The trainings were feasible and acceptable, evinced by high retention and compliance across time and condition. Although completing daily trainings across treatment types and modalities was associated with large decreases in LOC, there were no meaningful effects of either treatment type or modality, nor a significant interaction effect, on LOC or mechanistic variables. Future research should aim to increase the efficacy of ICT (both standard and VR-based) and test in fully-powered clinical trials.

RESUMO

Anhedonia is theorized as being relevant to binge eating spectrum disorders (BESDs) by palatable foods substituting the pleasure typically obtained from day-to-day activities. The current study examined whether anhedonia is associated with eating pathology at baseline and whether it predicts cognitive behavioral therapy (CBT) outcomes alone and when controlling for non-anhedonia depression symptoms. Ninety-three individuals from two randomized controlled trials completed the Eating Disorder Examination and Beck Depression Inventory-II at pre-, mid-, and post-treatment. Results showed that anhedonia was positively associated with global eating pathology at baseline, and larger pre- to mid-treatment anhedonia and non-anhedonia reductions predicted larger pre- to post-treatment global eating pathology reductions, though the anhedonia association was no longer significant when controlling for non-anhedonia depression. Anhedonia appears to be related to global eating pathology in CBT for BESDs, but not loss of control eating. Further research is needed to elucidate the relationship between anhedonia and BESDs.

RESUMO

PURPOSE: Black individuals are at risk for developing eating disorders (EDs), while also facing an increased mental health burden as a marginalized group. However, few studies have examined whether treatment-seeking Black individuals with EDs present with different symptom profiles than White individuals. This study sought to characterize baseline ED symptomatology in Black participants with bulimia nervosa spectrum or binge eating disorder spectrum pathology compared to White participants in a treatment-seeking sample. METHODS: The sample consisted of 33 Black participants and 126 White participants who participated in a clinical trial at a mid-Atlantic University from 2015 to 2020. Data was analyzed using chi-square and independent samples t-tests. RESULTS: Black participants were much less likely to engage in self-induced vomiting, despite being just as likely to meet criteria for a bulimia nervosa spectrum diagnosis and having similar rates of binge-eating and distress towards body image concerns. Black participants were more likely to experience obesity but maintained similar levels of body image concerns as White participants. CONCLUSION: Given the evidence that Black participants often are under-diagnosed, particularly with bulimia nervosa spectrum disorders, these results could suggest that weight biases and/or expectations that patients with bulimia nervosa spectrum disorders will primarily present with self-induced vomiting could be contributing to these diagnostic errors. LEVEL OF EVIDENCE: Level I, randomized controlled trials.

RESUMO

OBJECTIVE: Lesbian, Gay, and Bisexual (LGB) individuals generally experience eating disorders at higher rates than heterosexual individuals. While there is limited research examining why LGB individuals experience higher levels of eating pathology, emotion regulation (ER) deficits have been associated with higher rates of other forms of psychopathology in this population. The present study examined the impact of specific ER deficits on the relationship between LGB status and eating pathology. We hypothesized that 1) LGB individuals would report higher levels of ER deficits, and 2) ER deficits would mediate the relationship between LGB status and eating pathology. METHOD: Participants were 195 LGB and 193 heterosexual adults recruited via mTurk who completed self-report measures of eating pathology and ER deficits. RESULTS: One-way ANCOVA analyses revealed that LGB individuals reported higher levels of ER deficits compared to heterosexuals for all DERS subscales except for DERS-Awareness. Nearly all DERS subscales (DERS-Nonacceptance, DERS-Goals, DERS-Strategies, DERS-Impulse) significantly mediated the relationship between LGB status and eating pathology. DISCUSSION: Consistent with our hypotheses, LGB individuals reported higher levels of ER deficits compared to heterosexuals and specific ER deficits partially accounted for the relationship between LGB status and eating pathology. Future research should utilize longitudinal designs to examine whether the ER deficits identified in the present study prospectively predict eating pathology. Considering the immense mental health burden placed on the LGB community, it is essential that research continue to identify the unique needs of LGB individuals to more effectively treat and prevent psychopathology, including eating disorders, in this population.
