Prevalence of mood, panic and eating disorders in obese patients referred to bariatric surgery: patterns of comorbidity and relationship with body mass index

Prevalence and Correlates of Self-Reported ADHD Symptoms in Bariatric Patients: Focus on Mood and Anxiety Comorbidity, Disordered Eating, and Temperamental Traits

PURPOSE

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition characterized by inattention, hyperactivity, and impulsivity. A positive association between ADHD and obesity has been observed, especially in adult samples. In this study, prevalence and correlates of self-reported symptoms indicative of a positive screening for ADHD were examined in patients seeking bariatric treatment.

MATERIAL AND METHODS

The study sample was composed of 260 adult patients with obesity referred for bariatric surgery to the Obesity Center of the Endocrinology Unit in Pisa University Hospital between January 2006 and November 2016 (BMI ≥ 30 kg/m2; mean ± standard deviation = 46.27 ± 7.45 kg/m2). ADHD symptoms were identified using ADHD Symptom Check-List-90-R Screening Scale. Night-eating, binge-eating/purging behaviors, and temperamental and character traits were assessed in a subsample of 95 patients.

RESULTS

Thirty participants had a positive screening for ADHD (11.5%, 95% CI = 7.9-16.1%). Patients with a positive screening showed significantly higher rates of anxiety disorders (40% vs. 16.5%, χ2 = 7.97, p = 0.005) panic disorder (40% vs. 14.3%, χ2 = 10.48, p = 0.001), and a higher severity of psychopathological symptoms and sleep disturbances than those without. In subsample analyses, ADHD symptoms severity was associated with more bulimic behaviors (r = 0.31-0.46), greater harm avoidance (r = 0.45-0.66), less self-directedness (r =  - 0.44-0.63), and cooperativeness (r =  - 0.26-0.42).

CONCLUSION

ADHD symptoms may be common in patients with obesity seeking bariatric treatment and are positively associated with disordered eating, internalizing features, and maladaptive character traits.

The Impact of Negative Emotional Dysregulation on the Outcome of Bariatric Surgery in Patients with Severe Obesity: An Observational One-Year Follow-Up Study

Background: Psychiatric symptoms are highly prevalent in patients with severe obesity, often representing pivotal factors in the development and progression of this condition. This study examines the association between negative emotional dysregulation (NED) and weight loss following bariatric surgery. Methods: Ninety-nine patients were consecutively enrolled at the Obesity Center of the Pisa University Hospital between March 2019 and February 2021, during a routine psychiatric evaluation before bariatric surgery. Psychopathological dimensions were assessed using the Mini-International Neuropsychiatric Interview (MINI), the Reactivity, Intensity, Polarity, and Stability questionnaire in its 40-item version (RIPoSt-40), the Wender-Reimherr Adult Attention Deficit Disorder Scale (WRAADDS) and the Barratt Impulsiveness Scale (BIS-11). Based on a RIPoSt-40 cut-off score of 70, subjects were divided into two groups: with (NED+) and without (NED-) NED. Results: NED+ subjects had a higher rate of psychiatric comorbidities and eating disorders than NED- patients. Of the total sample, 76 underwent bariatric surgery, and 65 of them were re-evaluated one-year after surgery. Among them, 10 of 28 NED+ subjects (37.5%) had inadequate weight loss one year after surgery compared to 5 of 37 NED- subjects (13.5%) (p = 0.035, OR 3.55, 95%, C.I. 1.05-12.03). Conclusions: Our results suggest a significant association between NED and inadequate weight loss at one-year post surgery.

Biobehavioral approach to distinguishing panic symptoms from medical illness

Panic disorder is a common psychiatric diagnosis characterized by acute, distressing somatic symptoms that mimic medically-relevant symptoms. As a result, individuals with panic disorder overutilize personal and healthcare resources in an attempt to diagnose and treat physical symptoms that are often medically benign. A biobehavioral perspective on these symptoms is needed that integrates psychological and medical knowledge to avoid costly treatments and prolonged suffering. This narrative review examines six common somatic symptoms of panic attacks (non-cardiac chest pain, palpitations, dyspnea, dizziness, abdominal distress, and paresthesia), identified in the literature as the most severe, prevalent, or critical for differential diagnosis in somatic illness, including long COVID. We review somatic illnesses that are commonly comorbid or produce panic-like symptoms, their relevant risk factors, characteristics that assist in distinguishing them from panic, and treatment approaches that are typical for these conditions. Additionally, this review discusses key factors, including cultural considerations, to assist healthcare professionals in differentiating benign from medically relevant symptoms in panic sufferers.

Effect of obesity on mood regulation and eating attitudes in mental disorders

OBJECTIVE

The precise relationship between obesity and eating habits, attitudes, and emotion regulation is still ambiguous. The purpose of this study was to investigate possible correlations among body mass index, challenges related to managing emotions, and attitudes toward eating among adult participants with known psychiatric diagnoses.

METHODS

The body mass indices of participants were calculated, and data on eating styles were collected using the Dutch Eating Behavior Questionnaire. The level of difficulty in managing emotions was evaluated using the Difficulties in Emotion Regulation Scale.

RESULTS

The research findings indicated a meaningful positive association. An observation was made between body mass index and results from the Eating Attitude Test-40, as well as the restrained eating subdimension of the Dutch Eating Behavior Questionnaire. Conversely, a meaningful reverse relationship was identified between the scores of the "strategies" subdimension of the Difficulties in Emotion Regulation Scale. No meaningful differences in eating attitudes and emotion regulation were found between non-obese and obese patients.

CONCLUSION

While a partial and meaningful correlation was observed among body mass index, eating attitudes, and emotion regulation difficulties, it is suggested that factors such as patients' age, disease duration, current body mass index, and the simultaneous presence of depression and anxiety should be considered.

Predictors of Mental Health Outcomes in a Multidisciplinary Weight Management Program for Class 3 Obesity

This study aimed to examine the potential predictors of improvement in mental health outcomes following participation in an intensive non-surgical outpatient weight management program (WMP) in an Australian public hospital. This was a retrospective cohort study of all adults with Class 3 obesity (BMI ≥ 40 kg/m2) who enrolled in the WMP from March 2018 to June 2021. The participants completed the Eating Disorder Examination Questionnaire Short Version (EDE-QS), Kessler-10 Psychological Distress Scale, and 36-Item Short-Form Survey (SF-36) at baseline and 12-month follow-up. A total of 115 patients completed 12 months in the WMP and were included in the study, with 76.5% being female, a mean ± SD age at baseline of 51.3 ± 13.8 years, a weight of 146 ± 26 kg, and a BMI of 51.1 ± 8.6 kg/m2. The participants lost an average of 8.6 ± 0.2 kg over 12 months, and greater weight loss at follow-up was significantly associated with improved global EDE-QS scores, psychological distress, and improved mental health quality of life. However, improvements in most mental health outcomes were not predicted by weight loss alone. Notably, a lower eating disorder risk at baseline was associated with less psychological distress at follow-up and greater weight loss at follow-up. Our results also found an association between reduced psychological distress and reduced binge eating frequency. These findings support the inclusion components of obesity interventions that target the psychological correlates of obesity to support improved outcomes in people with Class 3 obesity. Future studies should aim to identify which aspects of the WMP helped improve people's psychological outcomes.

Assessing the Clinical Efficacy of a Virtual Reality Tool for the Treatment of Obesity: Randomized Controlled Trial

BACKGROUND

Virtual reality (VR) interventions, based on cognitive behavioral therapy principles, have been proven effective as complementary tools in managing obesity and have been associated with promoting healthy behaviors and addressing body image concerns. However, they have not fully addressed certain underlying causes of obesity, such as a lack of motivation to change, low self-efficacy, and the impact of weight stigma interiorization, which often impede treatment adherence and long-term lifestyle habit changes. To tackle these concerns, this study introduces the VR self-counseling paradigm, which incorporates embodiment and body-swapping techniques, along with motivational strategies, to help people living with obesity effectively address some of the root causes of their condition.

OBJECTIVE

This study aims to assess the clinical efficacy of ConVRself (Virtual Reality self-talk), a VR platform that allows participants to engage in motivational self-conversations.

METHODS

A randomized controlled trial was conducted with 68 participants from the bariatric surgery waiting list from the obesity unit of the Vall d'Hebron University Hospital in Barcelona, Spain. Participants were assigned to 1 of 3 groups: a control group (CG), which only received treatment as usual from the obesity unit; experimental group 1 (EG1), which, after intensive motivational interviewing training, engaged in 4 sessions of VR-based self-conversations with ConVRself, and underwent embodiment and body-swapping techniques; and experimental group 2 (EG2), which engaged in 4 VR-based sessions led by a virtual counselor with a prerecorded discourse, and only underwent the embodiment technique. In the case of both EG1 and EG2, the VR interventions were assisted by a clinical researcher. Readiness to change habits, eating habits, and psychological variables, as well as adherence and satisfaction with ConVRself were measured at baseline, after the intervention, 1 week after the intervention, and 4 weeks after the intervention.

RESULTS

Regarding the primary outcomes, EG1 (24/68, 35%) and EG2 (22/68, 32%) showed significant improvements in confidence to lose weight compared to the CG (22/68, 32%) at all assessment points (β=-.16; P=.02). Similarly, EG1 demonstrated a significant increase after the intervention in readiness to exercise more compared to the CG (β=-.17; P=.03). Regarding the secondary outcomes, EG1 participants showed a significant reduction in uncontrolled eating (β=.71; P=.01) and emotional eating (β=.29; P=.03) compared to the CG participants, as well as in their anxiety levels compared to EG2 and CG participants (β=.65; P=.01). In addition, participants from the experimental groups reported high adherence and satisfaction with the VR platform (EG1: mean 59.82, SD 4.00; EG2: mean 58.43, SD 5.22; d=0.30, 95% CI -0.30 to 0.89).

CONCLUSIONS

This study revealed that using VR self-conversations, based on motivational interviewing principles, may have benefits in helping people with obesity to enhance their readiness to change habits and self-efficacy, as well as reduce dysfunctional eating behaviors and anxiety.

Bariatric surgery efficacy in patients with mood disorders

BACKGROUND

Mood disorders are comorbid in patients with obesity and found in approximately 22.0% to 54.8% of patients who are eligible for bariatric surgery. Given the unclear effect of mood disorders on bariatric surgery outcomes, we aimed this study to assess the impact of mood disorders index bariatric surgery weight loss outcomes.

METHODS

A retrospective study institutional database of index bariatric surgery patients at University Hospitals Cleveland Medical Center between 2016 and 2018. The primary outcome of body mass index was followed over a 4-year period. The secondary outcomes measured were mortality and suicide rates. Mood disorders defined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, included depressive and bipolar disorders obtained from electronic medical records International Classification of Diseases, Tenth Revision, coding.

RESULTS

A total of 790 patients underwent bariatric surgery between 2016 and 2018. Of these, 15 patients were excluded due to death in the postoperative period or insufficient weight loss data, and a total of 775 patients (620 women and 155 men) were included. Two hundred and ninety-five (38.1%) had an electronic medical record mood disorder diagnosis before surgery, while 480 (61.9%) did not. Both groups had a significant decrease in postoperative body mass index; however, there was no significant difference in the body mass index change between the mood disorder group (mean = 37.63, standard deviation = 9.88) and the control group (mean = 38.72, standard deviation = 9.54; t[294] = 1.40; P = .1634).

CONCLUSION

Patients with mood disorders are as successful with weight loss after index bariatric surgery as those without mood disorders. There was no significant difference in mortality rates between the mood disorder group and the control group. Hence, mood disorders should not be prohibitive for weight loss surgery.

Effects of Sleeve Gastrectomy and Roux-en-Y Gastric Bypass on Escitalopram Pharmacokinetics: A Cohort Study

BACKGROUND

Changes in the gastrointestinal physiology after bariatric surgery may affect the pharmacokinetics of medications. Data on the impact of different surgical techniques on the pharmacokinetics of commonly prescribed antidepressants such as escitalopram are limited.

METHODS

This case-only prospective study investigated escitalopram-treated patients who underwent bariatric surgery at hospitals in Central Norway. Escitalopram concentrations were assessed using serial blood samples obtained during a dose interval of 24 hours preoperatively and at 1, 6, and 12 months, postoperatively. The primary outcomes were changes in the area under the time-concentration curve (AUC 0-24 ) with secondary outcomes, including full pharmacokinetic profiling. We performed repeated-measures analysis of variance for the AUC 0-24 and secondary outcomes.

RESULTS

Escitalopram-treated obese patients who underwent sleeve gastrectomy (n = 5) and Roux-en-Y gastric bypass (n = 4) were included. Compared with preoperative baseline, dose-adjusted AUC 0-24 values were within ±20% at all time points, postoperatively in the sleeve gastrectomy and oux-en-Y gastric bypass groups, with the largest changes occurring 1 month postoperatively (+14.5 and +17.2%, respectively). No statistically significant changes in any pharmacokinetic variables over time were reported; however, there was a trend toward increased maximum concentrations after surgery ( P = 0.069).

CONCLUSIONS

Our findings suggest that bariatric surgery has no systematic effect on the pharmacokinetics of escitalopram. However, because of the substantial interindividual variation, therapeutic drug monitoring can be considered to guide postoperative dose adjustments.

Psychopathological factors and personality dimensions on dysfunctional eating behaviors in a sample of individuals with obesity

Introduction

Obesity and eating disorders are considered to be part of a broad spectrum of disorders associated with weight issues and maladaptive eating styles. Several studies show that psychopathological and personality characteristics contribute to the development and maintenance of obesity and dysfunctional eating behaviors, showing a bidirectional relationship. The purpose of this study was to understand the role of psychopathological factors and personality dimensions on dysfunctional eating behaviors in a sample of individuals with obesity.

Methods

The study was conducted with 96 individuals with obesity (31 males and 65 females) who underwent psychological assessment. The instruments administered included the Cognitive Behavioral Assessment 2.0 - Primary Scales, the Minnesota Multiphasic Personality Inventory-2, and the Eating Disorder Inventory. Relationships between dysfunctional eating behaviors and personality and psychopathological factors were explored through mediation analysis.

Results and discussion

Our results showed that difficulties related to impulse control and behavior, along with negative and dysphoric emotions, may be associated with difficulties in eating behavior. Mediation analysis showed that the combination of depressive and obsessive-compulsive symptomatology may exacerbate or contribute to the occurrence of eating disorders. These psychopathological aspects should be taken into account during the assessment of patients who decide to undergo bariatric surgery and should be targets of specific psychological interventions.

Binge Eating (BE) and Obesity: Brain Activity and Psychological Measures before and after Roux-En-Y Gastric Bypass (RYGB)

Brain activity in response to food cues following Roux-En-Y Gastric Bypass (RYGB) in binge eating (BE) or non-binge eating (NB) individuals is understudied. Here, 15 RYGB (8 BE; 7 NB) and 13 no treatment (NT) (7 BE; 6 NB) women with obesity underwent fMRI imaging while viewing high and low energy density food (HEF and LEF, respectively) and non-food (NF) visual cues. A region of interest (ROI) analysis compared BE participants to NB participants in those undergoing RYGB surgery pre-surgery and 4 months post. Results were corrected for multiple comparisons using liberal (p < 0.006 uncorrected) and stringent (p < 0.05 FDR corrected) thresholds. Four months following RYGB (vs. no treatment (NT) control), both BE and NB participants showed greater reductions in blood oxygen level-dependent (BOLD) signals (a proxy of local brain activity) in the dorsomedial prefrontal cortex in response to HEF (vs. LEF) cues (p < 0.006). BE (vs. NB) participants showed greater increases in the precuneus (p < 0.006) and thalamic regions (p < 0.05 corrected) to food (vs. NF). For RYGB (vs. NT) participants, BE participants, but not NB participants, showed lower BOLD signal in the middle occipital gyrus (p < 0.006), whilst NB participants, but not BE participants, showed lower signal in inferior frontal gyrus (p < 0.006) in response to HEF (vs. LEF). Results suggest distinct neural mechanisms of RGYB in BE and may help lead to improved clinical treatments.

Eating disorders and emotional dysregulation are associated with insufficient weight loss after bariatric surgery: a 1-year observational follow-up study

PURPOSE

Subjects with obesity, especially those seeking bariatric surgery, exhibit high rates of mental disorders and marked psychopathological traits. The primary objective of this prospective, non-interventional study was to investigate whether the presence of different psychiatric disorders, attention deficit/hyperactivity disorder (ADHD) symptomatology and emotional dysregulation influenced weight loss at 1-year follow-up after surgery.

METHODS

Subjects consecutively referred for pre-surgical evaluation at the Obesity Center of Pisa University Hospital were recruited. Psychiatric diagnoses were made through the Mini-International Neuropsychiatric Interview (MINI) and ADHD symptomatology was assessed with the Wender-Reimherr Adult Attention Deficit Disorder Scale (WRAADDS). Emotional dysregulation was investigated through the WRAADDS and self-report questionnaires. After surgery, weight and obesity-related comorbidities were monitored during follow-up.

RESULTS

Of the 99 participants recruited, 76 underwent surgery and 65 could be reevaluated 1 year after surgery. Subjects with insufficient weight loss (excess body mass index loss ≤ 53%, n = 15) had more frequent lifetime binge eating disorder (BED) and BED-mood disorders comorbidity than subjects with favorable post-surgical outcome. Additionally, they scored higher on both physician-administered and self-report scales assessing emotional dysregulation, which represents a nuclear symptom of ADHD in adults. At the logistic regression analysis, older age, higher preoperative excess body mass index and greater affective instability were predictors of reduced weight loss at 1-year follow-up.

CONCLUSION

Emotional dysregulation seems to be associated with a worse outcome after bariatric surgery. Further studies with larger samples and longer follow-up are needed to confirm the influence of different psychiatric disorders and psychopathological traits on post-surgical outcome.

The impact of COVID-19 on medium term weight loss and comorbidities in patients undergoing bariatric surgery and its association with psychological wellbeing

BACKGROUND

The COVID-19 epidemic imposed significant stressors on individuals and changed how medical care is delivered. The affect that this stress has placed on the field of bariatric surgery and the associated outcomes is not well established.

METHODS

A retrospective review of a prospectively collected database from a single academic institution was conducted. Weight loss and comorbidity outcomes were compared between a cohort of patients operated on during the pandemic and a matched group operated on prior to COVID-19. GAD-7 and PHQ-9 questionnaires were used to assess for anxiety and depression, respectively.

RESULTS

A total of 329 and 155 patients were enrolled in the pre-pandemic and COVID-19 groups respectively. There were no significant differences in pre-operative BMI (p = 0.437) or comorbidities: Type II DM (p = 0.810), hypertension (p = 0.879), sleep apnea (p = 0.502), and hyperlipidemia (p = 0.227). Post-operatively, weight loss was comparable at all time points out to 1 year. Type II DM resolution rates were higher in the control cohort at 6 months (p = 0.007), but not at 12 months (p = 1.000). There was no statistically significant difference in resolution rates between the control group and the COVID-19 group for the other measured comorbidities. There was no difference in objective measures of anxiety and depression when comparing the two groups (both p > 0.05).

CONCLUSIONS

The COVID-19 pandemic has fundamentally changed how society and medical systems function. Focusing on pre-operative dietary training and screening for inadequately managed psychological comorbidities yielded similar weight loss outcomes notwithstanding the significant societal and individual stressors with which patients were faced.

Binge Eating Before and After Bariatric Surgery

PURPOSE OF REVIEW

The purpose is to review the state of the literature of binge eating in the context of bariatric surgery including prevalence, conceptualization, assessment, course, and related sequela throughout the perioperative continuum, particularly highlighting new advancements and future directions.

RECENT FINDINGS

Accurate assessment of binge eating in bariatric samples is essential for optimization of patient outcomes. Binge eating is less prevalent after bariatric surgery; however, prevalence rates increase over time. Most studies do not find a relationship between pre-operative binge eating and suboptimal weight outcomes after surgery. Refinement in understanding and conceptualization of post-operative binge eating is needed; new conceptualizations have proposed such a definition. Emerging constructs relevant to binge eating for bariatric patients include food addiction and food insecurity. Despite the introduction of formal diagnostic criteria for binge eating disorder, many uncertainties regarding the prevalence, course, and effects of binge eating currently exist; varied assessment methods continue to be a barrier to research on binge eating in bariatric surgery samples. Consensus on operational definitions for post-operative binge eating and best practices for assessment are areas for future consideration.

Clinical correlates and prognostic impact of binge-eating symptoms in major depressive disorder

Binge-eating (BE) symptoms are relatively common in major depressive disorder (MDD), but their prognostic role is not fully understood. This study compared two groups of patients with MDD experiencing or not BE symptoms to ascertain differences in terms of clinical manifestations, presence of bipolar features, and antidepressant treatment outcomes. The study involved 482 outpatients collected within the Combining Medications to Enhance Depression Outcomes (CO-MED) trial, who were assessed with scales for depressive and hypomanic symptomatology, suicidality, comorbid mental disorders, and childhood traumas. BE symptoms were reported in 95 patients (20%). Patients with MDD experiencing BE symptoms were characterized by higher scores of negative self-outlook ( P = 0.0018), negative outlook of future ( P = 0.0014), irritability ( P = 0.0043), comorbid anxiety disorders (generalized anxiety disorder: P = 0.0006; panic disorder: P &lt; 0.0001; social phobia: P &lt; 0.0001), obsessive-compulsive disorder ( P = 0.0053), hypomanic symptoms (increased talkativeness: P = 0.0029; reduced need for sleep: P = 0.0171), and suicidality (suicidal propensity: P = 0.0013; suicidal risk: P = 0.0148; lifetime suicidal behavior: P = 0.0052). BE symptoms (OR = 2.02; 95% CI = 1.06-3.84) and depression severity (OR = 1.04; 95% CI = 1.00-1.08) were independently associated with lifetime attempted suicide. The presence of BE symptoms might indicate higher severity of depressive disorder. Suicidal risk is a major issue in these patients, whereas the association between BE and bipolar features needs further research.

Prevalence and psychiatric comorbidities of night-eating behavior in obese bariatric patients: preliminary evidence for a connection between night-eating and bipolar spectrum disorders

PURPOSE

The co-occurrence of obesity, eating and mood disorders has been frequently reported in clinical and epidemiological settings. This study aimed to explore the prevalence of night-eating obese patients referred for bariatric surgery and to identify associated psychopathology and psychiatric comorbidity.

METHODS

The sample was composed of 121 obese patients consecutively enrolled between November 2010 and May 2012 during psychiatric evaluations for bariatric intervention. Clinical features and psychiatric diagnoses were collected. Night-eating was investigated through the administration of the Night-eating Questionnaires (NEQ) and was defined as the presence of self-reported evening hyperphagia and/or nocturnal ingestions. Binge-eating and purging behaviors and general psychopathology were respectively assessed using the Bulimic Investigatory Test, Edinburgh and the Symptom Checklist-90-Revised.

RESULTS

Night-eating was reported by twenty subjects (16.5%). Patients with night-eating behavior were significantly more frequently diagnosed with bipolar spectrum disorders and with comorbid eating and mood disorders in comparison with other patients. Night-eating patients showed significantly more binging/purging behaviors and greater severity of somatization, obsessive-compulsive symptoms, phobic anxiety, psychoticism and sleep disorders. Patients with bipolar disorder type 1 or 2 scored significantly higher than those without mood disorders at NEQ total score, mood/sleep and nocturnal ingestions subscales, but also scored significantly higher than other patients with mood disorders at the latter subscale.

CONCLUSION

Patients with evening hyperphagia and/or nocturnal ingestions should be carefully evaluated to detect possible bipolar spectrum disorders and other eating disorders. Prompt management of these conditions should be provided before bariatric interventions.

Restriction of range effects in post-metabolic and bariatric surgery outcomes research: considerations for clinical decision making

BACKGROUND

Preoperative psychopathology does not consistently predict postoperative outcomes in patients who undergo metabolic and bariatric surgery (MBS). Individuals with elevated pre-MBS psychopathology may be less likely to undergo surgery, which may create a floor effect given the limited range of scores on measures of psychopathology included in postoperative analyses, thereby decreasing the power to detect clinically significant differences between groups.

OBJECTIVES

Our objective was to compare rates of clinically significant pre-MBS psychopathology across domains of functioning in patients who did and did not undergo MBS: surgical completers (SCs, n = 286) and nonsurgical completers (NSCs, n = 125).

SETTING

Academic medical center, United States.

METHODS

Participants (n = 411) were a racially diverse sample of MBS candidates who completed a preoperative psychosocial evaluation including measures of disordered eating, alcohol and tobacco use, pain catastrophizing, anxiety, and depressive symptomatology.

RESULTS

Compared with SCs, NSCs had larger scale score variance on measures of psychopathology and were more likely to be Black; to report clinically significant scores on measures of binge eating, depression, anxiety, and pain catastrophizing; and to use tobacco.

CONCLUSION

Results support the presence of a restriction-of-range effect but do not demonstrate a floor effect. These data suggest that current outcome data for MBS patients may not generalize to those who report clinically significant psychopathology at the pre-MBS psychosocial evaluation and may warrant caution when using the current literature to inform clinical decision making for this group. Findings also suggest a need for interventions that will better engage Black patients.
