Dialectical behavior therapy for binge eating disorder

Associations between disordered eating and body focused repetitive behaviors in college students

Objective: College students with disordered eating (DE) are at increased risk of body focused repetitive behaviors (BFRBs). Both DE and BFRBs are described as impulsive and compulsive. However, the associations of impulsive DE with impulsive BFRBs and compulsive DE with compulsive BFRBs have not been examined. Methods: 191 college-aged students completed a survey of BFRBs and DE. Results: Participants who reported hair pulling were twice as likely to report clinically significant DE than those who denied hair pulling (p = .022). Participants who endorsed distressing hair pulling (p = .026), skin picking (p = .052), and nail biting (p = .094) were twice as likely to report clinically significant DE than those who were not distressed by these behaviors. Evidence did not support the association of BFRBs and DE along an impulsive/compulsive continuum. Conclusions: Results suggest that BFRBs and DE often co-occur, and the role of impulsivity and compulsivity in these behaviors is complex.

A Brief Online Mindfulness Intervention for Women's Sexual Desire: The BROWSE Study

With growing interest in developing digital health tools for treating sexual dysfunction, this pilot study aimed to determine feasibility and gather preliminary efficacy data of a self-led online mindfulness intervention in comparison to an online psychoeducational intervention for women's low sexual desire in a community sample (N = 57). After a four-week intervention, participants showed overall improvements on sexual functioning, orgasm, sexual self-pleasure, sexual self-image, and sexual distress, in both treatment arms. Majority completed assigned homework and felt the intervention enhanced their sexual well-being. This study supports the feasibility of a self-led online mindfulness intervention that could help inform future programs.

The effect of perceived stress on binge eating behavior among Chinese university students: a moderated mediation model

Introduction

Previous studies have demonstrated a strong link between perceived stress and binge eating behavior, but the psychological mechanisms underlying such phenomenon are not fully understood. The present study further addressed this issue in a life history framework, focusing on life history strategy and distress tolerance.

Methods

Firstly, we investigated the mediation role of life history strategy on the relationship between perceived stress and binge eating behavior. Secondly, we examined the moderation role of distress tolerance on the effect of perceived stress on life history strategy, as well as on the direct effect of perceived stress on binge eating behavior. We analyzed data from 1342 Chinese university students.

Results

Results indicated that life history strategy mediates the relationship between perceived stress and binge eating behavior; distress tolerance has significant moderating effects on the direct effect of perceived stress on binge eating behavior and their indirect effect via life history strategy.

Discussion

Therefore, distress tolerance skills training and life history-based interventions might be potentially effective ways to reduce binge eating behavior triggered by perceived stress.

Early evaluation of a DBT-informed online intervention for people with eating disorders

OBJECTIVES

Eating disorders (EDs) have a worldwide prevalence of 7.8%, with towering mortality rates and high healthcare costs. The current recommended treatment for EDs principally works by directly targeting ED thoughts and behaviours, but recovery rates are low. A multifaceted link between difficulties with emotions and EDs is now widely established, and newer third-wave therapies that aim to address these underlying emotion difficulties are promising. The current study piloted an online emotion self-help intervention which was co-developed with clinicians and people with lived experienced of EDs. The intervention aimed to specifically address difficulties with emotion identification and regulation, as well as unhelpful beliefs about emotions, which are believed to give rise to and maintain ED thoughts and behaviours.

METHOD

We recruited 39 people with self-reported EDs to test this intervention over a one-week period. Our participants were asked to complete a series of questionnaires measuring emotion processes and psychopathology on Day 1 (T1) before being given access to the intervention. Participants were then asked to practice the newly acquired skills for seven days, before taking the same questionnaires on Day 9 (T2). We also asked participants to qualitatively report on their experience of the intervention.

RESULTS

We found significant improvements in ED psychopathology (ED-15), depression (PHQ-9), and anxiety (GAD-7) pre- to post-intervention, with medium to large effect sizes. All our emotion variables namely alexithymia (TAS-20), difficulties regulating emotions (DERS-SF), and unhelpful beliefs about emotions (EBQ) also showed significant changes post-intervention with medium to large effect sizes. Most importantly, changes in emotion regulation processes were linked to improved eating psychopathology. The qualitative analysis corroborated this finding, highlighting how the intervention helped them form new beliefs about emotions, which helped them reduce ED behaviours.

DISCUSSION

Significant improvements in emotion processing and regulations, as well as psychopathology, along with positive qualitative feedback, suggest that the intervention effectively met its aims of increasing awareness of the link between emotions and eating psychopathology, providing help to identify and regulate emotions, and normalising emotional experiences. While our results are promising, further research is required to assess its effectiveness longer term and in clinical settings.

Preferences for coaching strategies in a personalized virtual coach for emotional eaters: an explorative study

Objectives

Emotional eating is recognized as a potential contributor to weight gain. Emotional eaters often hide their problems because of feelings of shame about their behavior, making it challenging to provide them with the necessary support. The introduction of a virtual coach might offer a potential solution in assisting them. To find out whether emotional eaters are receptive to online personalized coaching, we presented emotional eaters with two essential proto-typical problem situations for emotional eaters: "experiencing cravings" and "after giving in to cravings," and asked them whether they preferred one of the three coaching strategies presented: Validating, Focus-on-Change and Dialectical.

Methods

An experimental vignette study (2 × 3 design) was carried out. The vignettes featured two distinct personas, each representing one of the two common problem scenarios experienced by emotional eaters, along with three distinct coaching strategies for each scenario. To identify potential predictors for recognition of problem situations, questionnaires on emotional eating (DEBQ), personality traits (Big-5), well-being (PANAS), and BMI were administrated.

Results

A total of 62% of the respondents identified themselves with "after giving in to cravings" and 47% with "experiencing cravings." BMI, emotional eating and emotional stability appeared to be predictors in recognizing both the problem situations. In "experiencing cravings," the participating women preferred Dialectical and the Validation coaching strategies. In the "after giving in to cravings" condition, they revealed a preference for the Dialectical and the Focus-on-Change coaching strategies.

Conclusion

Using vignettes allowed a less threatening way of bringing up sensitive topics for emotional eaters. The personas representing the problem situations were reasonably well recognized. To further enhance this recognition, it is important for the design and content of the personas to be even more closely related to the typical problem scenarios of emotional eaters, rather than focusing on physical characteristics or social backgrounds. This way, users may be less distracted by these factors. With the knowledge gained about the predictors that may influence recognition of the problem situations, design for coaching can be more customized. The participants represented individuals with high emotional eating levels, enhancing external validity.

Features of Addiction in Binge-Eating Disorder: Considerations for Screening and Treatment

Similarities have been reported between the diagnostic and associated characteristics of binge-eating disorder (BED) and substance-related and non-substance-related disorders. This has resulted in interest in using addiction models to inform clinical care for people with BED. The purpose of this paper was to review features of addiction in BED with a focus on clinical implications. First, we briefly summarize similarities and differences in diagnostic and mechanistic features and symptoms for BED and food addiction, substance-related disorders, and non-substance-related disorders. Then we review aspects of addiction in BED that have clinical implications for screening and treatment of this condition. Similarities in diagnostic criteria between BED and substance-related and non-substance-related disorders include loss of control, greater use than intended, continued use despite adverse consequences, and marked distress. Addiction models may help inform aspects of clinical care of BED, particularly for shared antecedents and mechanisms underlying both disorders and to enhance engagement in treatment. Yet, there are large gaps in evidence regarding the effects of many aspects of addiction models to BED. More research is needed to examine the safety and efficacy of using addiction theories and frameworks for clinical strategies for BED.

Eating disorder patients with and without PTSD treated in residential care: discharge and 6-month follow-up results

INTRODUCTION

We studied whether provisional posttraumatic stress disorder (PTSD) moderated discharge (DC) and 6-month follow-up (FU) outcomes of multi-modal, integrated eating disorder (ED) residential treatment (RT) based upon principles of cognitive processing therapy (CPT).

METHODS

ED patients [N = 609; 96% female; mean age (± SD) = 26.0 ± 8.8 years; 22% LGBTQ +] with and without PTSD completed validated assessments at admission (ADM), DC and 6-month FU to measure severity of ED, PTSD, major depressive disorder (MDD), state-trait anxiety (STA) symptoms, and eating disorder quality of life (EDQOL). We tested whether PTSD moderated the course of symptom change using mixed models analyses and if ED diagnosis, ADM BMI, age of ED onset and LGBTQ + orientation were significant covariates of change. Number of days between ADM and FU was used as a weighting measure.

RESULTS

Despite sustained improvements with RT in the total group, the PTSD group had significantly higher scores on all measures at all time points (p ≤ .001). Patients with (n = 261) and without PTSD (n = 348) showed similar symptom improvements from ADM to DC and outcomes remained statistically improved at 6-month FU compared to ADM. The only significant worsening observed between DC and FU was with MDD symptoms, yet all measures remained significantly lower than ADM at FU (p ≤ .001). There were no significant PTSD by time interactions for any of the measures. Age of ED onset was a significant covariate in the EDI-2, PHQ-9, STAI-T, and EDQOL models such that an earlier age of ED onset was associated with a worse outcome. ADM BMI was also a significant covariate in the EDE-Q, EDI-2, and EDQOL models, such that higher ADM BMI was associated with a worse ED and quality of life outcome.

CONCLUSIONS

Integrated treatment approaches that address PTSD comorbidity can be successfully delivered in RT and are associated with sustained improvements at FU. Improving strategies to prevent post-DC recurrence of MDD symptoms is an important and challenging area of future work.

Effects of DBT-based interventions on alexithymia: a systematic review

While dialectical behavior therapy (DBT) appears effective for some psychiatric conditions commonly associated with alexithymia, it is unclear whether DBT improves difficulties experienced by alexithymic individuals. This review investigated the current evidence on the effectiveness of DBT-based interventions in improving alexithymia. A qualitative synthesis of studies that investigated the efficacy of DBT on self-reported alexithymia was performed, identifying eligible studies using EBSCO/Essentials, Google Scholar, PubMed, Web of Science, and PsychINFO databases. Eight studies were identified. Overall, the results were inconclusive due to the heterogeneity of the studies but suggest that DBT-based interventions may be associated with self-reported decreases in alexithymia and increases in the ability to identify emotional states. The literature is limited by significant methodological problems, such as the low number of controlled trials, small samples, and high variability between DBT programs, which increases the risk of bias across study outcomes. More research is needed to reach conclusions regarding the effectiveness of DBT in improving alexithymia. Future studies should conduct randomized controlled trial designs (primarily with active treatment control conditions), greater standardization of DBT-based interventions, and a more in-depth examination of the level of participant involvement in long-term DBT-based interventions may help to understand whether DBT improves alexithymia difficulties.

Application of Dialectical Behaviour Therapy in treating common psychiatric disorders: study protocol for a scoping review

INTRODUCTION

Dialectical behaviour therapy (DBT) is a well-known intervention for treating borderline personality disorder, and has been increasingly adapted for other disorders. Standard DBT consists of four treatment modes, delivered over a year. Adaptations to DBT include changes to modes of delivery, treatment length, and skills modules taught to clients, or incorporating interventions from other evidence-based therapies. There is a need to synthesise existing evidence on DBT so that stakeholders-clinicians, researchers and policymakers-can understand how it has been provided for various psychiatric conditions, and whether it has been effective.

METHODS AND ANALYSIS

This study proposes a scoping review conducted according to Arksey and O'Malley's (2005) procedures, to map and summarise the literature on DBT interventions for treating a range of psychiatric concerns. Electronic databases (ie, the Cochrane Central Register of Controlled Trials, PubMed, PsycINFO, SCOPUS, EBSCOhost and ProQuest Dissertations and Theses), conference proceedings and the US National Institutes of Health Ongoing Trial Register will be searched for intervention studies that involve a control or comparison group, and that report quantitative data on pre/post-measures for psychiatric symptom severity. The initial search was conducted on 18 September 2020, and data charting has not commenced. An update will be performed in September 2022, pending this protocol's publication. Data charting will collect individual studies' characteristics, methodology and reported findings. Outcomes will be reported by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for Scoping Reviews.

ETHICS AND DISSEMINATION

No ethical approval is required for this study. The goal of dissemination is to keep DBT stakeholders abreast on latest updates in clinical applications of DBT. Findings from this research are intended to inform a more specific topic of study (eg, a meta-analysis), to further aid in the development of DBT interventions for psychiatric populations.

REGISTRATION DETAILS

The study protocol was pre-registered with the Open Science Framework on 24 August 2021 (https://osf.io/vx6gw).

Longitudinal relationships between muscle dysmorphia symptoms and suicidal ideation

INTRODUCTION

Muscle Dysmorphia (MD) is a severe subtype of body dysmorphic disorder (BDD) that shares symptomatic overlap with eating disorders. Although associations between eating disorders/BDD and suicidality are well documented, research has rarely examined associations between MD symptoms and suicidality, which is concerning given MD is associated with additional suicide risk factors compared with these disorders. Further, existing associations between MD symptoms and suicidality have yet to establish temporal ordering for these relationships. Therefore, the current study investigated longitudinal relationships between MD symptoms and suicidal ideation to establish the direction of the MD-suicidality relationship.

METHODS

Participants were 272 US men displaying sub-clinical MD symptoms who completed self-report measurement at three time points over 6 weeks. Longitudinal relationships between MD symptoms and suicidal ideation were examined using a three-wave autoregressive cross-lagged model.

RESULTS

Certain MD symptoms were longitudinally predicted by suicidal ideation. Specifically, suicidal ideation longitudinally predicted increased drive for size and appearance intolerance.

CONCLUSIONS

Results may suggest that individuals engage in MD symptoms potentially to cope with distressing thoughts of suicide. Clinicians should provide clients with comorbid MD and suicidality with appropriate coping tools to manage distress from suicidal thoughts outside of engaging in compulsive exercise characteristic of MD symptoms.

Mapping the landscape and structure of global research on binge eating disorder: Visualization and bibliometric analysis

BACKGROUND

Binge-eating disorder (BED) is a clinical syndrome and is considered the most common type of eating disorder. However, our understanding of the global performance and progress of BED research is limited.

AIM

To describe and perform a bibliometric analysis of the state of BED research.

METHODS

The term ‘Binge eating’ was searched in the title throughout the previous year’s up to December 31, 2020. We searched the Scopus and Reference Citation Analysis for publications on Binge eating. The VOSviewer software version 1.6.17 was used to produce the network visualization map of the most frequent author, collaborative relationships between countries/regions, and to determine the hotspots related to binge eating research. In addition, conventional bibliometric indicators were generated.

RESULTS

The search strategy found 2713 total articles and an average of 62 articles per year. Among them, ‘Article’ represented 82.49% of the publications (n = 2238 articles) and was the most frequent type, followed by reviews (n = 243; 8.96%). The number of publications increased steadily during the last decade of the study period. One hundred and thirty-two countries contributed to binge eating research, with 1495 (55.11%) articles published in the United States, followed by Italy with 256 (9.44%), the United Kingdom with 183 (6.75%), and Germany with 182 (6.71%). Currently, the main hot topics related to BED are ‘type of treatment and management and treatment provided to BED”; “processes and pathways to binge eating”; and ‘diagnosis, signs and symptoms, comorbidities and prevalence and associated factors with BED’.

CONCLUSION

The number of publications has increased noticeably during the previous decade. There are indeed relatively few publications on BED from low-and middle-income nations, so much is to be learned from the experience of all countries. Studies on this topic are critical in all countries to discover risk factors and effective intervention measures. Although our findings are preliminary, they imply that the future prospects for interventions aimed at BED management are bright, focusing on complex models of care and long-term maintenance of therapeutic gains.

Dialectical behavior therapy compared to cognitive behavior therapy in binge-eating disorder: An effectiveness study with 6-month follow-up

OBJECTIVE

To evaluate whether the results of a quasi-randomized study, comparing dialectical behavior therapy for binge-eating disorder (DBT-BED) and an intensive, outpatient cognitive behavior therapy (CBT+) in individuals with BED, would be replicated in a nonrandomized study with patients who more closely resemble everyday clinical practice.

METHOD

Patients with (subthreshold) BED (N = 175) started one of two group treatments: DBT-BED (n = 42) or CBT+ (n = 133), at a community eating disorder service. Measures of eating disorder pathology, emotion regulation, and general psychopathology were examined at end of treatment (EOT) and at 6-month follow-up using generalized linear models with multiple imputation.

RESULTS

Both treatments lead to substantial decreases on primary and secondary measures. Statistically significant, medium-size differences between groups were limited to global eating disorder psychopathology (d = -.62; 95% CI = .231, .949) at EOT and depressive symptoms at follow-up (d = -.45; 95% CI = .149, 6.965), favoring CBT+. Dropout of treatment included 15.0% from CBT+ and 19.0% from DBT-BED (difference nonsignificant).

DISCUSSION

Decreases in global eating disorder psychopathology were achieved faster with CBT+. Overall, improvements in DBT-BED were comparable to those observed in CBT+. Findings of the original trial, favoring CBT+ on the number of OBE episodes, emotional dysregulation and self-esteem at EOT, and on eating disorder psychopathology and self-esteem at follow-up, were not replicated. With similar rates of treatment dropout and about half of the therapy time used in CBT+, DBT-BED can be considered a relevant treatment for BED in everyday clinical practice.

PUBLIC SIGNIFICANCE

In this effectiveness study, dialectical behavior therapy (DBT) resulted in clinically relevant improvements in individuals with binge eating disorder. Changes were broadly comparable to those of cognitive behavior therapy (CBT), the current treatment of choice. Although CBT resulted in decreases in eating disorder psychopathology faster, there was a trend toward relapse in CBT at 6-month follow-up. Therefore, the less costly DBT-program can be considered a relevant treatment in clinical practice.

An Open Trial Examining Dialectical Behavior Therapy Skills and Behavioral Weight Loss for Adults With Emotional Eating and Overweight/Obesity

Third-wave cognitive behavioral interventions for weight loss have shown promise. However, sparse data exists on the use of dialectical behavior therapy for weight loss. Adapted dialectical behavior therapy skills programs may be especially well suited for adults who engage in emotional eating and are seeking weight loss. Dialectical behavior therapy is skills-based, shares theoretical links to emotional eating, and is effective in treating binge eating. The current study examined the feasibility, acceptability, and preliminary efficacy of Live FREE: FReedom from Emotional Eating, a 16-session group-based intervention. A total of 87 individuals expressed interest in the program, and 39 adults with overweight/obesity (BMI ≥25) and elevated self-reported emotional eating were enrolled. Live FREE targeted emotional eating in the initial sessions 1-9, and sessions 10-16 focused primarily on behavioral weight loss skills while continuing to reinforce emotion regulation training. Assessments were administered at baseline, posttreatment, and 6-month follow up. Enrolled participants were primarily female (97.4%) and Caucasian (91.7%). Treatment retention was strong with participants attending an average of 14.3 sessions and 89.7% of participants completing the intervention. On average, participants lost 3.00 kg at posttreatment, which was maintained at follow-up. Intent-to-treat analyses showed improvements in key outcome variables (self-reported emotional eating, BMI, emotion regulation) over the course of the intervention. Combining dialectical behavior therapy skills with conventional behavioral weight loss techniques may be an effective intervention for adults with overweight/obesity who report elevated emotional eating.

Changes in cognitive and behavioral control after lamotrigine and intensive dialectical behavioral therapy for severe, multi-impulsive bulimia nervosa: an fMRI case study

PURPOSE

Adults with bulimia nervosa (BN) and co-occurring emotional dysregulation and multiple impulsive behaviors are less responsive to existing interventions. Initial data suggest that the combination of Dialectical Behavior Therapy (DBT) and a mood stabilizer, lamotrigine, significantly reduces symptoms of affective and behavioral dysregulation in these patients. Identifying candidate neurobiological mechanisms of change for this novel treatment combination may help guide future randomized controlled trials and inform new and targeted treatment development. Here, we examined neurocognitive and symptom changes in a female patient with BN and severe affective and behavioral dysregulation who received DBT and lamotrigine.

METHODS

Go/no-go task performance data and resting-state functional MRI scans were acquired before the initiation of lamotrigine (after 6 weeks in an intensive DBT program), and again after reaching and maintaining a stable dose of lamotrigine. The patient completed a battery of symptom measures biweekly for 18 weeks over the course of treatment.

RESULTS

After lamotrigine initiation, the patient made fewer errors on a response inhibition task and showed increased and new connectivity within frontoparietal and frontolimbic networks involved in behavioral and affective control. Accompanying this symptom improvement, the patient reported marked reductions in bulimic symptoms, behavioral dysregulation, and reactivity to negative affect, along with increases in DBT skills use.

CONCLUSION

Improved response inhibition and cognitive control network connectivity should be further investigated as neurocognitive mechanisms of change with combined DBT and lamotrigine for eating disorders. Longitudinal, controlled trials integrating neuroimaging and symptom measures are needed to fully evaluate the effects of this treatment.

LEVEL OF EVIDENCE

IV: Evidence obtained from multiple time series with or without the intervention, such as case studies.

A systematic review of sociodemographic reporting and representation in eating disorder psychotherapy treatment trials in the United States

OBJECTIVE

Eating disorders (EDs) were once conceptualized as primarily affecting affluent, White women, a misconception that informed research and practice for many years. Abundant evidence now discredits this stereotype, but it is unclear if prevailing "evidence-based" treatments have been evaluated in samples representative of the diversity of individuals affected by EDs. Our goal was to evaluate the reporting, inclusion, and analysis of sociodemographic variables in ED psychotherapeutic treatment randomized controlled trials (RCTs) in the US through 2020.

METHODS

We conducted a systematic review of ED psychotherapeutic treatment RCTs in the US and examined the reporting and inclusion of gender identity, age, race/ethnicity, sexual orientation, and socioeconomic status (SES) of enrolled participants, as well as recruitment methods, power analyses, and discussion of limitations and generalizability.

RESULTS

Our search yielded 58 studies meeting inclusion criteria dating back to 1985. Reporting was at times incomplete, absent, or centered on the racial/gender majority group. No studies reported gender diverse participants, and men and people of color were underrepresented generally, with differences noted across diagnoses. A minority of papers considered sociodemographic variables in analyses or acknowledged limitations related to sample characteristics. Some progress was made across the decades, with studies increasingly providing full racial and ethnic data, and more men included over time. Although racial and ethnic diversity improved somewhat, progress appeared to stall in the last decade.

DISCUSSION

We summarize findings, consider context and challenges for RCT researchers, and offer suggestions for researchers, journal editors, and reviewers on improving representation, reporting, and analytic practices.

PUBLIC SIGNIFICANCE

Randomized controlled trials of eating disorder psychotherapeutic treatment in the US are increasingly reporting full race/ethnicity data, but information on SES is inconsistent and sexual orientation absent. White women still comprise the overwhelming majority of participants, with few men and people of color, and no gender-diverse individuals. Findings underscore the need to improve reporting and increase representation to ensure evidence-based treatments are effective across and within diverse groups.

Mindfulness and Eating Disorders: A Network Analysis

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 (N = 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.

Depression and anxiety mediate the relationship between insomnia and eating disorders in college women

Objective: This study examined the associations between insomnia, anxiety, and depression in college women with eating disorders (EDs). Participants: Six hundred and ninety women from 28 US colleges who screened positive for an ED were assessed for psychiatric comorbidities. Women were, on average, 22.12 years old, mostly White (60.1%) and undergraduates (74.3%). Methods: Two mediation models were tested to determine if depression and/or anxiety mediated the relationship between insomnia and ED symptomatology. Results: One-fifth of the sample (21.7%) reported clinically moderate and severe levels of insomnia. Both depression (B = .13, p <. 001) and anxiety (B = .13, p <. 001) significantly mediated the relationship between insomnia and ED psychopathology. Conclusions: Insomnia is relatively common in college-age women with EDs. Findings suggest that this association between ED and sleep disturbances can be explained, in part, by changes in depression and anxiety. Clinicians should consider incorporating mental health assessments for insomnia, depression, and anxiety into current ED prevention, intervention, and screening efforts on college campuses.

Body Image and Eating Disorders Among South Asian American Women: What Are We Missing?

This study used focus group methodology to examine South Asian (SA) American women's conceptualizations of eating disorders (EDs) and body dissatisfaction, and their perspectives regarding cultural influences on these conditions. Using a qualitative descriptive approach, seven focus groups were conducted (N = 54, mean age = 20.11 years, SD = 2.52). Themes (n = 15) were organized according to the amended objectification theory framework. Women described experiences of cultural stressors specifically related to living in the United States, and weight stigma from multiple sources, especially older women (e.g., mothers, relatives, and aunties). Participants also experienced pressures to achieve competing body and appearance ideals ("thin" and "healthy"). In addition, they reported pressures to possess light skin, dark black hair, minimal body hair, and marry young, and noted these pressures negatively impacted their body esteem. Findings indicate that a combination of "traditional" and culturally-influenced factors are important to consider when conceptualizing eating pathology and body image in young SA American women.

Implementation of brief dialectical behavior therapy skills training among borderline personality disorder patients in Malaysia: feasibility, acceptability, and preliminary outcomes

AIM/BACKGROUND

Even though dialectical behavior therapy (DBT) has received substantial empirical support in treating patients with borderline personality disorder (BPD), fewer studies have evaluated whether a brief DBT skills group may be effective in improving clinical outcomes in this population. Further, less is known regarding the feasibility and outcomes of DBT beyond Euro-American contexts. This paper describes outcomes from a pilot study examining the feasibility, acceptability, and clinical outcomes following completion of a shortened, 14-week DBT skills group in a sample of Muslim-majority BPD patients in Malaysia.

METHODS

Twenty patients were recruited from a public hospital and attended DBT skills groups in an outpatient clinic. Participants completed measures assessing psychological symptoms, self-harm behaviors, suicidal ideation, emotion regulation difficulties, self-compassion, and well-being pre- and post-intervention.

RESULTS

There were significant reductions in depressive symptoms, stress, and emotion regulation difficulties, as well as increases in self-compassion and well-being from pre- to post-intervention. A trend was found for decreases in frequency and types of non-suicidal self-harm behaviors, suicidal ideation, and anxiety symptoms. Qualitative content analyses of participants' feedback indicated that the vast majority of participants perceived a positive impact from the skills group, with mindfulness and distress tolerance being rated frequently as skills that were beneficial.

CONCLUSION

These preliminary findings suggest that DBT skills training is feasible and acceptable in a Muslim-majority, low resource clinical setting, and holds promise in improving clinical outcomes among BPD patients in Malaysia.

Two decades of mindfulness-based interventions for binge eating: A systematic review and meta-analysis

OBJECTIVE

Mindfulness-based interventions (MBIs) are being increasingly used as interventions for eating disorders including binge eating. This systematic review and meta-analysis aimed to assess two decades of research on the efficacy of MBIs in reducing binge eating severity.

METHODS

We searched PubMed, Scopus and Cochrane Library for trials assessing the use of MBIs to treat binge eating severity in both clinical and non-clinical samples. The systematic review and meta-analysis was pre-registered at PROSPERO (CRD42020182395).

RESULTS

Twenty studies involving 21 samples (11 RCT and 10 uncontrolled samples) met inclusion criteria. Random effects meta-analyses on the 11 RCT samples (n = 618: MBIs n = 335, controls n = 283) showed that MBIs significantly reduced binge eating severity (g = -0.39, 95% CI -0.68, -0.11) at end of trial, but was not maintained at follow-up (g = -0.06, 95% CI, -0.31, 0.20, k = 5). No evidence of publication bias was detected. On the Cochrane Risk of Bias Tool 2, trials were rarely rated at high risk of bias and drop-out rates did not differ between MBIs and control groups. MBIs also significantly reduced depression, and improved both emotion regulation and mindfulness ability.

CONCLUSION

MBIs reduce binge eating severity at the end of trials. Benefits were not maintained at follow-up; however, only five studies were assessed. Future well-powered trials should focus on assessing diversity better, including more men and people from ethnic minority backgrounds.

General impulsivity in binge-eating disorder

BACKGROUND

The nature and significance of impulse-control difficulties in binge-eating disorder (BED) are uncertain. Most emerging research has focused on food-specific rather than general impulsivity. The current study examines the clinical presentation of patients with BED categorized with and without clinical levels of general impulsivity.

METHOD

A total of 343 consecutive treatment-seeking patients with BED were categorized as having BED with general impulsivity (GI+; N = 73) or BED without general impulsivity (GI-: N = 270) based on structured diagnostic and clinical interviews. The groups were compared on demographic, developmental, and psychological features, and on rates of psychiatric and personality comorbidity.

RESULTS

Individuals with BED and general impulsivity (GI+) reported greater severity of eating-disorder psychopathology, greater depressive symptoms, and greater rates of comorbidity than those without general impulsivity (GI-).

CONCLUSIONS

A subtype of individuals with BED and general impulsivity may signal a more severe presentation of BED characterized by heightened and broader psychopathology. Future work should investigate whether these impulse-control difficulties relate to treatment outcomes.

The Impact of Repeated Attachment Priming on Paranoia, Mood and Help-Seeking Intentions in an Analogue Sample

Attachment security priming effects therapeutic change in people with depression and anxiety. Preliminary studies indicate that visualising secure attachment memories also reduces paranoia in non-clinical and clinical groups, probably due to a decrease in cognitive fusion. Benefits to clinical populations depend on the sustainability of these effects and the impact on help-seeking behaviours. The combination of paranoia and an insecure-avoidant attachment style is likely to be a particular barrier to help seeking. We used a longitudinal experimental design to test the impact of repeated attachment priming on paranoia, mood and help-seeking intentions and whether cognitive fusion mediates these effects. Seventy-nine people with high levels of non-clinical paranoia, aged 18-50 years (M = 20.53, SD = 4.57), were randomly assigned to a secure or insecure-avoidant priming condition. Participants rehearsed the visualisation prime on four consecutive days and were assessed on standardised measures of paranoia, positive and negative affect, help-seeking intentions and cognitive fusion. A series of mixed-model analyses of variance showed that security priming decreases paranoia, negative affect and cognitive fusion and increases positive affect and help seeking, compared to insecure-avoidant priming. Examining the impact of primed attachment (rather than measured attachment style) allows us to draw conclusions about the causal processes involved; mediation analyses showed indirect effects of the primes on paranoia and negative affect through cognitive fusion. With a growing understanding of (1) the impact of security priming on paranoia, affect and help-seeking behaviours, (2) causal mechanisms and (3) sustainability of effects, security priming may be developed into a viable intervention for clinical populations.

Dialectical Behaviour Therapy Improves Emotion Dysregulation Mainly in Binge Eating Disorder and Bulimia Nervosa: A Systematic Review and Meta-Analysis

Emotion dysregulation is a transdiagnostic phenomenon in Eating Disorders (ED), and Dialectical Behaviour Therapy (DBT) (which was developed for reducing dysregulated emotions in personality disorders) has been employed in patients with ED. This systematic review and meta-analysis investigated whether the effect of DBT was stronger on emotion dysregulation, general psychopathology, and Body Mass Index (BMI) in participants with ED, when compared to a control group (active therapy and waitlist). Eleven studies were identified in a systematic search in accordance with PRISMA guidelines. Most studies included participants with Binge Eating Disorder (BED) (n = 8), some with Bulimia Nervosa (BN) (n = 3), and only one with Anorexia Nervosa (AN). The pooled effect of DBT indicated a greater improvement in Emotion Regulation (ER) (g = −0.69, p = 0.01), depressive symptoms (g = −0.33, p < 0.00001), ED psychopathology (MD = −0.90, p = 0.005), Objective Binge Episodes (OBE) (MD = −0.27, p = 0.003), and BMI (MD = −1.93, p = 0.01) compared to the control group. No improvement was detected in eating ER following DBT (p = 0.41). DBT demonstrated greater efficacy compared with the control group in improving emotion dysregulation, ED psychopathology, and BMI in ED. The limitations included the small number of studies and high variability.

Skills-homework completion and phone coaching as predictors of therapeutic change and outcomes in completers of a DBT intensive outpatient programme

OBJECTIVES

Dialectical behaviour therapy (DBT) emphasizes generalization of skills to the patient's real-world context as a primary mechanism of change in treatment. To promote generalization, DBT includes weekly skills-focused homework assignments and as-needed phone coaching. Despite this central function of generalization in DBT, research on these treatment components is limited. The current study addresses this research gap by assessing the association of homework and phone coaching to DBT treatment outcomes.

DESIGN

A longitudinal study design explored the extent to which (a) completion of skills homework and (b) frequency of phone coaching were associated with therapeutic changes and treatment outcomes in a DBT intensive outpatient programme (DBT-IOP).

METHOD

Medical records and diary cards of 56 patients who had completed a four-month treatment cycle of DBT-IOP were reviewed and coded for proportion of skills homework completed, frequency of phone coaching calls, and reported urges for and engagement in suicide, non-suicidal self-injury, illicit or non-prescribed substance use, and alcohol use behaviours.

RESULTS

Completion of skills homework and frequency of phone coaching were significantly associated with (a) reduced urges for suicide, non-suicidal self-injury, illicit or non-prescribed substance use, and alcohol use from the beginning to end of treatment and (b) a lower likelihood of engaging in any of these behaviours during the final month of treatment.

CONCLUSIONS

Results suggest that within a DBT programme modified for an intensive outpatient setting, skills homework and phone coaching may enhance therapeutic change and outcomes in target behaviours. These generalization methods appear to be important ingredients of DBT effectiveness.

PRACTITIONER POINTS

In dialectical behaviour therapy (DBT), therapeutic skills homework and phone coaching are specifically designed to promote generalization of skills from the therapeutic context to the patient's real-world contexts. In a DBT intensive outpatient programme, patient engagement with therapeutic homework and phone coaching were associated with favourable therapeutic change and outcomes in target urges and behaviours. Clinicians may consider a patient's lack of homework completion and/or phone coaching to be early warning signs of poor therapeutic progress within dialectical behaviour therapy.

Outcomes of brief versions of Dialectical Behaviour Therapy for diagnostically heterogeneous groups in a routine care setting

INTRODUCTION

Brief versions of Dialectical Behaviour Therapy (DBT) may enhance patient outcomes in diverse service settings. This study examined the effectiveness of two DBT-informed treatments for diagnostically heterogeneous groups in routine practice: 5-day group training in DBT skills (DBT-5) and a 12-week DBT program (DBT-12).

METHODS

: Depression, anxiety, stress, borderline symptoms, self-esteem, and general mental wellbeing were measured at pre-and post-treatment in a sample of inpatients and outpatients (N=395). Rates of clinically significant change on these measures were calculated and effect sizes benchmarked against prior DBT outcome studies. Readmission rates were used to measure treatment response maintenance.

RESULTS

: Scores on all measures improved significantly from pre- to post-treatment. DBT-5 and DBT-12 yielded similar effect sizes compared to prior DBT outcome studies. At least 43.5% of patients were classified as recovered or improved regarding borderline symptoms at the end of both DBT-5 and DBT-12. Readmission rates were also low (5%-6.8%).

CONCLUSIONS

Brief DBT-informed treatments may offer a fast reduction in symptoms and quicker return to functioning.

Updates in the treatment of eating disorders in 2020: a year in review in eating disorders: the journal of treatment & prevention

Several important studies advancing treatment of eating disorders were published in Eating Disorders: The Journal of Treatment & Prevention in 2020. This review summarizes the recent contributions to the literature on the treatment of eating disorders, including dialectical behavior therapy, yoga for positive embodiment, and treatment innovations in children and adolescents with eating disorders. Dialectical behavior therapy can be effectively used in complex eating disorder presentations, such as with comorbid substance use disorder and with suicidal behavior, and can be adapted for culturally-responsive treatments for binge eating and for guided self-help. Yoga may promote positive embodiment, which is supported by conceptual frameworks, studies evaluating yoga treatment interventions, and systematic reviews. Advances in eating disorder treatment for children and youth include the development of the Emotional Eating Scale adapted for children and adolescents, a review of primary care interventions for eating disorder treatment, and siblings' perspectives on eating disorder treatment. Research on novel methods including telementoring and innovative treatment modalities invoking feminism are promising areas of future research.

From BIS to binge: The role of negative affect in the pathway between personality and binge eating

Recent research has highlighted the utility of using revised Reinforcement Sensitivity Theory (RST) to further understand the individual differences that influence binge eating behaviours. The current study draws on both RST and theoretical models that implicate negative affect in binge eating, with the aim of identifying indirect pathways between individual differences in RST systems and binge eating as mediated through negative affect. Undergraduate students (n = 229, M = 22.67 years of age, SD = 8.95, 76% female) completed self-report measures of revised reinforcement sensitivities, negative affect and binge eating symptoms. Bootstrapped tests of indirect effects showed that negative affect mediated the pathway between the Behavioural Inhibition System (BIS) and binge eating symptoms. Additionally, negative affect mediated the pathway between rash impulsivity and binge eating symptoms. This study supports and extends previous research by highlighting the experience of negative affect as a possible mechanism through which heightened BIS and rash impulsivity leads to binge eating.

Believing emotions are uncontrollable is linked to eating disorder psychopathology via suppression and reappraisal

OBJECTIVE

Research suggests that beliefs about emotional controllability influence the use of emotion regulation strategies, which in turn impact psychological health and illness. However, no research has yet investigated whether emotional controllability is linked to eating psychopathology. The current study investigates whether these concepts are related, as individuals with eating disorders have problems with emotion regulation.

METHOD

We collected self-report data from 718 participants from a community sample using validated questionnaires, and ran mediational analyses to assess the relationship between emotional controllability and eating psychopathology, via reappraisal and suppression, two emotion regulation strategies.

RESULTS

Our mediational analyses suggest that believing emotions to be uncontrollable relates to high levels of suppression (β = -.08), low levels of reappraisal (β = .19) and poorer eating disorder psychopathology (β = -.11). Reappraisal and suppression were found to partially mediate the relationship between emotional controllability and eating psychopathology.

DISCUSSION

The current study has demonstrated relationships that support investigations relating emotional controllability, emotion regulation and psychological health. This research has potential implications for developing interventions to target beliefs about emotions in order to help improve emotion regulation skills and eating psychopathology.

Effectiveness of a brief form of group dialectical behavior therapy for binge-eating disorder: Case series in a routine clinical setting

OBJECTIVE

While there is evidence to support the use of group dialectical behavior therapy (DBT) in the treatment of binge-eating disorder (BED), treatment is relatively long compared with other evidence-based treatments. This study explored the effectiveness of brief DBT groups for BED, delivered in a routine community setting.

METHOD

Eighty-four adults with BED entered 10-week DBT group treatment in a community eating disorders service. In total, 12 groups were conducted. Patients completed measures of eating disorder pathology, anxiety, depression, and emotional eating at the start and end of treatment, and at 1-month follow-up. Frequency of weekly binges was recorded.

RESULTS

Outcomes were similar to those of longer versions of DBT, with an attrition rate of 26%, and significant reductions in eating disorder psychopathology and emotional eating by the end of treatment and at follow-up. Over 50% of patients were abstinent from binge eating by Session 4.

DISCUSSION

Group DBT delivered in a 10-session format is clinically equivalent to longer versions of the same treatment. Future research is required to explore patterns of change and to demonstrate replicability under controlled conditions, but these findings are promising for the efficient delivery of effective treatment and reducing waiting times.

Influence of suppression and reappraisal on eating-related symptoms and ruminative thinking in anorexia nervosa and bulimia nervosa

The goal of the present study was to investigate the influence of expressive suppression and cognitive reappraisal on eating-related symptomatology in anorexia nervosa (AN) and bulimia nervosa (BN). Secondly, on the background of theoretical models proposing a reciprocal relationship between suppression and rumination, we sought to understand whether inhibition of emotional expression also affects ruminative thinking in eating disorders. Women with AN (n = 39), BN (n = 37) and a control group (CG, n = 41) were randomly assigned to either engage in suppression or reappraisal during a sadness-eliciting film clip. Levels of drive to eat, anticipated loss of control over eating and ruminative thoughts were rated before and after the induction of emotion regulation. Induced expressive suppression led to a decrease of reported drive to eat in AN and an increase of anticipated loss of control over eating in BN. All groups responded to suppression with greater rumination, whereas no significant changes were found for reappraisal. Mediation analyses on trait questionnaires pointed to rumination as a partial mediator of the correlation between suppression and eating disorder pathology. Results are discussed in line with recent empirical research and current emotion regulation theories.

A Qualitative Analysis of College Counseling Center Staff Experiences of the Utility of Dialectical Behavior Therapy Programs on Campus

Dialectical behavior therapy (DBT) is an evidence-based practice for suicidal and self-injuring behavior with growing popularity in college counseling centers (CCCs). With the exception of a single, quantitative study, no research to date investigates how DBT is used in CCCs or what factors influence program implementation. We conducted qualitative interviews with 15 CCC staff that were delivering DBT programs in order to inform a more richly detailed understanding of the process of developing and implementing a DBT program housed in a CCC.

Disordered eating in the postpartum period: Role of psychological distress, body dissatisfaction, dysfunctional maternal beliefs and self-compassion

The present cross-sectional study tested the affect regulation model of disordered eating for women in the postpartum period, whereby disordered eating is used to cope with psychological distress. Two hundred and two women who had given birth in the last two years completed an online survey of self-report measures of study variables. Path analyses supported the primary hypothesis: negative affect mediated relationships between body dissatisfaction, dysfunctional maternal beliefs, negative components of self-compassion and disordered eating behaviours, particularly binge eating. Results suggest that negative affect plays a central role in postpartum disordered eating. Interventions to address maladaptive emotion regulation strategies, specifically targeting body image distress and self-critical maternal thoughts may improve eating behaviours for this population.

Group-based DBT skills training modules are linked to independent and additive improvements in emotion regulation in a heterogeneous outpatient sample

Objective: Dialectical Behavior Therapy (DBT) was initially developed to treat symptoms of Borderline Personality Disorder (BPD), but has also been shown to improve symptoms of several other mental health conditions. Emotion regulation difficulties comprise a key target of DBT as well as a common challenge for individuals with depression, anxiety, PTSD, and other conditions. The current study investigated the impact of a DBT skills-training group on emotion regulation, and whether improvement in specific facets of emotion regulation would be linked to training in specific modules.Method: One hundred and thirty-six patients diagnosed with heterogeneous mental health conditions participated in the study. Patients were enrolled in the group on a rolling basis, and emotion regulation was assessed at the beginning and end of every six- to eight-week module.Results: Mixed model analysis revealed that each DBT skills-training module (i.e., mindfulness, distress tolerance, interpersonal effectiveness, and emotion regulation) was associated with improvements in emotion regulation (all Bonferroni corrected ps < .003).Conclusions: These findings add to the growing literature on the applicability of DBT skills-training to heterogeneous psychological conditions, particularly when patients' challenges reflect underlying difficulties with emotion regulation.

Application of three different coaching strategies through a virtual coach for people with emotional eating: a vignette study

BACKGROUND

Around 13% of the world's population suffers from obesity. More than 40% of people with obesity display emotional eating behaviour (eating in response to negative emotions or distress). It is an alternate to more effective coping strategies for negative emotions. Our study explored the opportunities for helping adults with emotional overeating using a virtual coach, aiming to identify preferences for tailored coaching strategies applicable in a personal virtual coach environment. Three different coaching strategies were tested: a validating, a focus-on-change, and a dialectical one - the latter being a synthesis of the first two strategies.

METHODS

A qualitative study used vignettes reflecting the two most relevant situations for people with emotional eating: 1. experiencing negative emotions, with ensuing food cravings; and 2. after losing control to emotional eating, with ensuing feelings of low self-esteem. Applied design: 2 situations × 3 coaching strategies.

PARTICIPANTS

71 adult women (Mage 44.4/years, range 19-70, SD = 12.86) with high scores on the DEBQ-emotional eating scale (Memo 3.65, range 1.69-4.92, SD = .69) with mean BMI 30.1 (range 18-46, SD = 6.53). They were recruited via dieticians' practices, were randomly assigned to the conditions and asked how they would face and react to the presented coaching strategies. Data were transcribed and a thematic analysis was conducted.

RESULTS

Qualitative results showed that participants valued both the validating coaching strategy and the focus-on-change strategy, but indicated that a combination of validation and focus-on-change provides both mental support and practical advice. Data showed that participants differed in their level of awareness of the role that emotions play in their overeating and the need for emotion-regulation skills.

CONCLUSION

The design of the virtual coach should be based on dialectical coaching strategies as preferred by participants with emotional eating behaviour. It should be tailored to the different stages of awareness of their emotions and individual emotion-regulation skills.

Psychosocial Interventions for Reducing Suicidal Behaviour and Alcohol Consumption in Patients With Alcohol Problems: A Systematic Review of Randomized Controlled Trials

OBJECTIVE

We aimed to provide a synthesis and evaluation of psychosocial interventions to prevent suicide and reduce self-harm, as well as alcohol intake, for patients with alcohol problems.

METHODS

The systematic review was carried out according to the PRISMA guidelines and considered articles published in English from all countries. Terms relating to suicidality and alcohol problems were used to search Medline, EMBASE and PsycINFO databases. Randomized controlled trials of psychosocial interventions targeted for outpatient settings were included.

RESULTS

Six studies with a total of 400 participants were included. Two investigated dialectic behavioural therapy (DBT), one internet-delivered DBT, one dynamic deconstructivist psychotherapy (DDP) and two integrated cognitive behavioural therapy (CBT). Face to face and online DBT was significantly associated with abstinence and reductions in consumption with only a trend for a reduction in suicide attempts in one study relative to treatment at usual (TAU). DDP yielded significant reductions in alcohol consumption and suicide attempts versus community care. CBT was significantly effective relative to TAU in reducing alcohol use and suicide attempts in one trial with adolescents but not in another trial in an adult population.

CONCLUSION

Integrated CBT has promise for adolescents, DBT may be helpful for alcohol patients with borderline personality disorder and iDBT may be useful for the wider community with heavy alcohol use. However, given the paucity of studies and the exploratory nature of these trials, there is currently no strong evidence for an effective psychosocial intervention to reduce alcohol consumption and suicidal behaviour in adults with problematic alcohol use.

The treatment of binge eating disorder with cognitive behavior therapy and other therapies: An overview and clinical considerations

Binge eating disorder (BED) is a public health problem in several countries. BED is commonly associated with comorbidities such as obesity, diabetes, and depression. Notwithstanding the health problems associated with BED, evidence-based treatments for BED are not widely used by healthcare professionals worldwide. Thus, we provide an overview of the leading evidence-based psychological therapies for BED, with the intention of informing healthcare professionals and the general community and facilitating greater provision of treatment. Cognitive behavior therapy (CBT) for BED is briefly presented, focusing mainly on adaptations and stages of the cognitive behavior therapy-enhanced (CBT-E) transdiagnostic model for eating disorders. We also succinctly discuss the use of CBT in combination with weight management interventions or pharmacotherapy, as well as the use of interpersonal therapy and dialectical behavior therapy for BED. We conclude that there is a variety of evidence-based psychological therapies that can be used by a variety of healthcare professionals (not only by psychologists) to help reduce binge eating and associated psychopathology in people with BED. Given the high and increasing prevalence of BED, as well as the availability of effective evidence-based treatments, we encourage more healthcare professionals to explore up-skilling to assist people with BED.

Group dialectical behavioral therapy for binge-eating disorder: Outcomes from a community case series

OBJECTIVE

Whilst there is evidence to support the use of group dialectical behavioral therapy (DBT) in the treatment of binge-eating disorder (BED), few studies have reported on its effectiveness when delivered in routine clinical practice. This study addressed this gap by exploring the effectiveness of group DBT for BED when delivered in a community eating disorder service.

METHOD

Participants were 56 adults who presented with BED, and were offered a 20-week DBT group. Eight groups were conducted. Measures of eating disorder pathology, anxiety, depression and emotion regulation were completed at start and end of treatment, and one-month follow-up.

RESULTS

The attrition rate was 16.1%. Abstinence rates (no objective binges in the previous month) were approximately 60% at the end of treatment and 50% at follow-up. There were significant reductions in eating disorder psychopathology (but not in mood) by end of treatment and improvements were maintained at follow-up.

DISCUSSION

Group DBT is an acceptable and effective treatment for adults with BED when delivered in a routine community setting. Findings are broadly comparable with those from research trials. The lack of significant effect on mood suggests that DBT can be effective by teaching new emotion-regulation skills, rather than changing mood per se.

Targeting affect leads to reduced paranoia in people with psychosis: a single case series

BACKGROUND

Current psychological interventions for psychosis focus primarily on cognitive and behavioural management of delusions and hallucinations, with modest outcomes. Emotions are not usually targeted directly, despite evidence that people with psychosis have difficulty identifying, accepting and modifying affective states.

AIMS

This study assessed the impact of emotion regulation skills practice on affect and paranoia in seven people who met criteria for a diagnosis of schizophrenia or schizoaffective disorder.

METHOD

The study utilised a single case ABA design and measured emotion regulation skills, affect and paranoia over baseline, intervention and withdrawal of intervention phases. We predicted that eight sessions of skills rehearsal would lead to improved emotion regulation, reduced negative affect, increased positive affect, and reduced paranoia.

RESULTS

Most participants were able to learn to regulate their emotions, and reported reduced negative affect and paranoia. There was no clear pattern of change for positive affect.

CONCLUSIONS

These findings suggest that emotion can be targeted in psychosis, and is associated with reduced paranoia. Emotion regulation may constitute a key treatment target in cognitive behavioural therapy for psychosis.

DBT-informed treatment in a partial hospital and intensive outpatient program: the role of step-down care

Few studies to date have examined Partial Hospital (PH) and Intensive Outpatient (IOP) programs that utilize a Dialectical Behavior Therapy (DBT)-informed model. Preliminary findings suggest that DBT-informed PH programs are effective in reducing clinical symptoms; however, less is known about IOP programs as well as step-down care models. The present study utilized clinically relevant outcome indices and included a heterogeneous clinical sample. Specifically, the present study assessed pre-post data to examine changes in symptoms of depression, anxiety, hopelessness, and overall degree of suffering from intake to discharge in DBT-informed PH and IOP programs as well as a step-down condition (PH to IOP). Participants included 205 adults (ages M = 35.28, SD = 12.49). The sample was predominantly female (N = 139, 67.8%) and Caucasian (N = 181, 88.3%). The sample was divided into three distinct groups: PH program patients, PH to IOP program step-down patients, and IOP patients. Findings indicated significant symptom reduction from intake to discharge for all three conditions. There were no significant differences in mean change scores in symptom reduction between the three groups. Severity of depression symptoms at intake predicted program placement. However, type of program did not predict significant changes in symptoms from intake to discharge. This DBT-informed PH and IOP program was successful at reducing various psychiatric symptoms in the sample. Clinicians might consider the advantages of placing patients with higher symptoms of depression into PH programs with the intention of transitioning to step-down care through IOP programs that utilize DBT.

Meta-analysis on the long-term effectiveness of psychological and medical treatments for binge-eating disorder

OBJECTIVE

Long-term effectiveness is a critical aspect of the clinical utility of a treatment; however, a meta-analytic evaluation of psychological and medical treatments for binge-eating disorder (BED), including weight loss treatments, is outstanding. This meta-analysis sought to provide a comprehensive evaluation of the long-term effectiveness in diverse treatments for BED regarding a range of clinically relevant outcomes.

METHOD

Based on a systematic search up to February 2018, 114 published and unpublished randomized-controlled (RCTs), nonrandomized, and uncontrolled treatment studies, totaling 8,862 individuals with BED (DSM-IV, DSM-5), were identified and analyzed using within-group random-effect modeling.

RESULTS

Effectiveness (regarding binge-eating episodes and abstinence, eating disorder and general psychopathology) up to 12 months following treatment was demonstrated for psychotherapy, structured self-help treatment, and combined treatment, while the results regarding body weight reduction were inconsistent. These results were confirmed in sensitivity analyses with RCTs on the most common treatments-cognitive-behavioral therapy and self-help treatment based on this approach. Follow-up intervals longer than 12 months were rarely reported, mostly supporting the long-term effectiveness of psychotherapy. Few follow-up data were available for pharmacotherapy, and behavioral and self-help weight loss treatment, while follow-up data were lacking for pharmacological and surgical weight loss treatment. Study quality varied widely.

DISCUSSION

This comprehensive meta-analysis demonstrated the medium-term effectiveness of psychotherapy, structured self-help treatment, and combined treatment for patients with BED, and supported the long-term effectiveness of psychotherapy. The results were derived from uncontrolled comparisons over time. Further long-term high quality research on psychological and medical treatments for BED is required.

Promoting a Healthy Lifestyle through Mindfulness in University Students: A Randomized Controlled Trial

The present study explored the effects of a second-generation mindfulness-based intervention known as flow meditation (Meditación-Fluir) in the improvement of healthy life behaviors. A sample of university students (n = 51) in Spain were randomly assigned to a seven-week mindfulness treatment or a waiting list control group. Results showed that compared to the control group, individuals in the mindfulness group demonstrated significant improvements across all outcome measures including healthy eating habits (balanced diet, intake rate, snacking between meals, decrease in consumption by negative emotional states, increased consumption by negative emotional states, amount of consumption, meal times, consumption of low-fat products), tobacco, alcohol, and cannabis consumption, and resting habits. There were differences between males and females in some of these variables and a better effect of the treatment was evident in the females of the experimental group when compared to the males. The flow meditation program shows promise for fostering a healthy lifestyle, thus decreasing behaviors related to maladaptive eating, tobacco, alcohol, and cannabis consumption as well as negative rest habits in university students. This mindfulness program could significantly contribute to the treatment of eating disorders and addictions, wherein negative emotional states and impulsivity are central features of the condition.

Emotion regulation mediates relationships between perceived childhood invalidation, emotional reactivity, and emotional eating

Dialectical Behavior Therapy (DBT) is informed by the biosocial model which suggests that emotional sensitivity and childhood invalidation interact to influence emotion dysregulation, leading to behavioral disorders. Although adapted DBT interventions have resulted in improved emotional eating, little research has been conducted to examine whether key aspects of the biosocial model apply to emotional eating. Adults ( N = 258) were enrolled via Amazon’s Mechanical Turk. Three separate mediation analyses were performed using Hayes’ SPSS macro. Results showed that emotion regulation difficulties mediated the relationships between biosocial variables (i.e. perceived maternal and paternal invalidation and emotional reactivity) and emotional eating.

Emotion Regulation Difficulties During and After Partial Hospitalization Treatment Across Eating Disorders

Emotion regulation deficits are associated with eating disorder (ED) symptoms, regardless of eating disorder diagnosis. Thus, recent treatment approaches for EDs, such as dialectical behavior therapy (DBT), have focused on teaching patients skills to better regulate emotions. The present study examined changes in emotion regulation among adult patients with EDs during DBT-oriented partial hospital treatment, and at follow-up (M[SD] = 309.58[144.59] days from discharge). Exploratory analyses examined associations between changes in emotion regulation and ED symptoms. Patients with anorexia nervosa, restricting (AN-R, n = 77), and binge-eating/purging subtype (AN-BP, n = 46), or bulimia nervosa (BN, n = 118) completed the Difficulties in Emotion Regulation Scale (DERS) at admission, discharge, and follow-up. Patients with BN demonstrated significant improvements across all facets of emotion dysregulation from admission to discharge and maintained improvements at follow-up. Although patients with AN-BP demonstrated statistically significant improvements on overall emotion regulation, impulsivity, and acceptance, awareness, and clarity of emotions, from admission to discharge, these improvements were not significant at follow-up. Patients with AN-R demonstrated statistically significant improvements on overall emotion dysregulation from treatment admission to discharge. Changes in emotion regulation were moderately correlated with changes in ED symptoms over time. Results support different trajectories of emotion regulation symptom change in DBT-oriented partial hospital treatment across ED diagnoses, with patients with BN demonstrating the most consistent significant improvements.
