Cognitive Behavioral Therapy for Bariatric Surgery Patients: Preliminary Evidence for Feasibility, Acceptability, and Effectiveness

Psychological predictors of adherence to lifestyle changes after bariatric surgery: A systematic review

Objective

Adherence to lifestyle changes after bariatric surgery is associated with better health outcomes; however, research suggests that patients struggle to follow post-operative recommendations. This systematic review aimed to examine psychological factors associated with adherence after bariatric surgery.

Methods

PubMed, PsycInfo, and Embase were searched (from earliest searchable to August 2022) to identify studies that reported on clinically modifiable psychological factors related to adherence after bariatric surgery. Retrieved abstracts (n = 891) were screened and coded by two raters.

Results

A total of 32 studies met the inclusion criteria and were included in the narrative synthesis. Appointment attendance and dietary recommendations were the most frequently studied post-operative instructions. Higher self-efficacy was consistently predictive of better post-operative adherence to diet and physical activity, while pre-operative depressive symptoms were commonly associated with poorer adherence to appointments, diet, and physical activity. Findings were less inconsistent for anxiety and other psychiatric conditions.

Conclusions

This systematic review identified that psychological factors such as mood disorders and patients' beliefs/attitudes are associated with adherence to lifestyle changes after bariatric surgery. These factors can be addressed with psychological interventions; therefore, they are important to consider in patient care after bariatric surgery. Future research should further examine psychological predictors of adherence with the aim of informing interventions to support recommended lifestyle changes.

Telephone-based cognitive behavioural therapy for patients with postoperative bariatric surgery to manage COVID-19 pandemic-related mental health issues and distress (TELE-BARICARE): a protocol for a randomised controlled trial

INTRODUCTION

Bariatric surgery is currently the most effective treatment for obesity, and is performed yearly in over 8000 patients in Canada. Over 50% of those who live with obesity also have a history of mental health disorder. The COVID-19 pandemic has made it difficult for people living with obesity to manage their weight even after undergoing bariatric surgery, which combined with pandemic-related increases in mental health distress, has the potential to adversely impact obesity outcomes such as weight loss and quality of life. Reviews of virtual mental health interventions during COVID-19 have not identified any interventions that specifically address psychological distress or disordered eating in patients with obesity, including those who have had bariatric surgery.

METHODS AND ANALYSIS

A randomised controlled trial will be conducted with 140 patients across four Ontario Bariatric Centres of Excellence to examine the efficacy of a telephone-based cognitive behavioural therapy intervention versus a control intervention (online COVID-19 self-help resources) in postoperative bariatric patients experiencing disordered eating and/or psychological distress. Patients will be randomised 1:1 to either group. Changes in the Binge Eating Scale and the Patient Health Questionnaire 9-Item Scale will be examined between groups across time (primary outcomes). Qualitative exit interviews will be conducted, and data will be used to inform future adaptations of the intervention to meet patients' diverse needs during and post-pandemic.

ETHICS AND DISSEMINATION

This study has received ethics approvals from the following: Clinical Trials Ontario (3957) and the University Health Network Research Ethics Committee (22-5145), the Board of Record. All participants will provide written informed consent prior to enrolling in the study. Results will be made available to patients with bariatric surgery, the funders, the supporting organisations and other researchers via publication in peer-reviewed journals and conference presentations.

Behavioral Interventions After Bariatric Surgery

Purpose of Review

Bariatric surgery is the most effective and durable treatment for severe obesity. Postoperative behavioral weight management approaches are available for optimizing weight change for both short- and long-term outcomes.

Recent Findings

Varying settings such as groups and telemedicine along with techniques such as cognitive behavioral therapy have been assessed in the post-bariatric surgery population. The assessment and application of these programs have been limited due to methodological, financial, and attrition-related constraints.

Summary

This review aims to summarize the current evidence for different postoperative behavioral interventions on postoperative outcomes, specifically highlighting weight loss. Future opportunities for study include mechanisms for overcoming some of the barriers to implementing these programs in clinical, non-research settings.

The Impact of Telephone-Based Cognitive Behavioral Therapy on Mental Health Distress and Disordered Eating Among Bariatric Surgery Patients During COVID-19: Preliminary Results from a Multisite Randomized Controlled Trial

Background

Patients undergoing bariatric surgery have high rates of psychiatric comorbidity, which may increase their vulnerability to COVID-19-related mental health distress. Exacerbation of mental health distress and disordered eating could have significant negative effects on long-term weight management and quality of life for these patients if untreated.

Objective

To determine the efficacy of a telephone-based cognitive behavioral therapy (Tele-CBT) intervention in improving depressive, anxiety, and disordered eating symptoms during COVID-19.

Methods

Participants were recruited as part of a larger randomized controlled trial study (clinicaltrials.gov ID: NCT03315247) between March 2020 and March 2021 and randomized 1:1 to receive Tele-CBT or standard bariatric care. Outcomes of Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Emotional Eating Scale (EES), and Binge Eating Scale (BES) were measured at baseline, immediately post-intervention, and 3 months post-intervention. Linear mixed models were used to test the effect of intervention group, time, and group-by-time interaction for each outcome.

Results

Eighty-one patients were included in the intention-to-treat analysis. Mean (SD) age of participants was 47.68 (9.36) years and 80.2% were female. There were significant group-by-time interactions for all outcomes and significant differences between groups across time. There were significant decreases in mean GAD-7 (p = 0.001), PHQ-9 (p < 0.001), EES-Total (p = 0.001), EES-Anger (p = 0.003), EES-Anxiety (p < 0.001), EES-Depression (p < 0.001), and BES (p = 0.002) scores for the Tele-CBT group at post-intervention and follow-up when compared to baseline and the control group.

Conclusion

Tele-CBT is a feasible and effective treatment for improving psychological distress and disordered eating among post-operative bariatric surgery patients during the COVID-19 pandemic.

Graphical abstract

"If you're offered help, take it": A qualitative study examining bariatric patients' experience of telephone-based cognitive behavioural therapy

The increased recognition of patients' mental health needs after bariatric surgery has resulted in the emergence of accessible psychosocial interventions; however, there is a dearth of literature on patient experience and satisfaction with these interventions. We explored patients' perceptions and experiences of telephone-based cognitive behavioural therapy (Tele-CBT) in this qualitative study. Ten participants from the Toronto Western Hospital Bariatric Surgery Program in Toronto, Canada who completed the Tele-CBT (ClinicalTrials.gov Identifier: NCT02920112) were individually interviewed from November 2014 to June 2016 until thematic saturation occurred (ie, no more new coding groups emerged). Interviews were transcribed, independently coded, checked for discrepancies, and analysed using grounded theory. Four themes emerged: (1) participants were generally satisfied with Tele-CBT (eg, therapeutic alliance, resources provided, relevance of therapy to their own bariatric journey), (2) participants noticed emotional, cognitive, and behavioural changes following therapy, (3) the optimal time to deliver the Tele-CBT was when weight loss plateaued, generally at one-year post-surgery, and (4) participants found the telephone modality convenient. CBT was generally found to be helpful and the telephone format increased convenience and accessibility. Patients reported learning skills and receiving resources that could help them improve their well-being following bariatric surgery.

Patient perspectives on psychological care after bariatric surgery: A qualitative study

Psychological interventions may be effective in improving adherence after bariatric surgery; however, there is limited research on patients' willingness to engage with psychological aftercare. This study aimed to qualitatively explore patient perspectives on psychological services in the bariatric setting. Participants reported believing that psychological care is essential for treatment success and indicated that they wanted support with adjusting to changes in lifestyle, self-identity, and relationships after surgery. Participants suggested that psychological aftercare should be recommended by their medical team and incorporated into standard management after bariatric surgery. These findings can be used to inform the design of services for bariatric surgery patients.

Cognitive Behavioral Therapy Versus Usual Care Before Bariatric Surgery: One-Year Follow-Up Results of a Randomized Controlled Trial

BACKGROUND

Although early results of bariatric surgery are beneficial for most patients, some patients regain weight later. Cognitive behavioral therapy (CBT) has been suggested as a way to improve patients' psychological health and maintaining weight loss in the longer term. The added value of preoperative CBT to bariatric surgery was examined. Pre- and posttreatment and 1-year follow-up data are presented.

METHODS

In a multi-center randomized controlled trial, CBT was compared to a treatment-as-usual (TAU) control group. Measurements were conducted pre- and posttreatment/pre-surgery (T0 and T1) and at 1-year post-surgery (T2). Patients in the intervention group received 10 individual, weekly sessions of preoperative CBT focused on modifying thoughts and behaviors regarding eating behavior, physical exercise, and postoperative life style. Outcome measures included weight change, eating behavior, eating disorders, depression, quality of life, and overall psychological health.

RESULTS

Though no significant differences between conditions were found per time point, in the CBT, condition scores on external eating, emotional eating, depressive symptoms, and psychological distress decreased significantly more over time between pre- (T0) and posttreatment (T1) pre-surgery compared to TAU. No significant time x condition differences were found at 1-year post-surgery (T2).

CONCLUSIONS

Compared to TAU, preoperative CBT showed beneficial effects on eating behavior and psychological symptoms only from pretreatment to posttreatment/pre-surgery, but not from pre-surgery to 1-year post-surgery. Preoperative CBT does not seem to contribute to better long-term outcomes post-surgery. Recent studies suggest that the optimal time to initiate psychological treatment may be early in the postoperative period, before significant weight regain has occurred.

Food Addiction Is Associated with Binge Eating and Psychiatric Distress among Post-Operative Bariatric Surgery Patients and May Improve in Response to Cognitive Behavioural Therapy

The current study examined clinical correlates of food addiction among post-operative bariatric surgery patients, compared the clinical characteristics of patients with versus without food addiction, and examined whether a brief telephone-based cognitive behavioural therapy (Tele-CBT) intervention improves food addiction symptomatology among those with food addiction. Participants (N = 100) completed measures of food addiction, binge eating, depression, and anxiety 1 year following bariatric surgery, were randomized to receive either Tele-CBT or standard bariatric post-operative care, and then, repeated the measure of food addiction at 1.25 and 1.5 years following surgery. Thirteen percent of patients exceeded the cut-off for food addiction at 1 year post-surgery, and this subgroup of patients reported greater binge eating characteristics and psychiatric distress compared to patients without food addiction. Among those with food addiction, Tele-CBT was found to improve food addiction symptomatology immediately following the intervention. These preliminary findings suggest that Tele-CBT may be helpful, at least in the short term, in improving food addiction symptomatology among some patients who do not experience remission of food addiction following bariatric surgery; however, these findings require replication in a larger sample.

The effectiveness of psychosocial interventions to support psychological well-being in post-operative bariatric patients: A systematic review of evidence

BACKGROUND

Bariatric surgery is considered an effective obesity management intervention for individuals with a BMI greater than 40, or 35 with co-morbidities. However, research documents that psychological difficulties prevalent amongst individuals seeking surgery may persist post-operatively. This systematic review aims to assess the evidence to show which psychosocial interventions support psychological well-being post-operatively.

METHODS

The review is registered with Prospero (CRD42018100280), complying with PRISMA guidelines. The research protocol included grey literature and database searches of psychosocial interventions for post-operative bariatric patients, between November 2017 and September 2019. The primary outcome was psychological well-being; secondary outcomes included weight loss maintenance and quality of life (QoL). The primary reviewer screened titles and extracted data. Study quality was assessed independently by two reviewers, using the Effective Public Health Practice Project criteria. Due to heterogeneity across studies, narrative synthesis was considered suitable for data analysis.

RESULTS

Ten studies met inclusion criteria. Psychosocial intervention content was delivered in a variety of ways (e.g., clinic, internet-based). Overall, participants (N = 382, Mage = 46.4) receiving psychosocial interventions post bariatric surgery, demonstrated improvements in psychological well-being and weight loss maintenance, compared to baseline measures and/or controls. The strength of evidence is currently limited by the small number of studies found and study quality, limiting the power to detect clinically meaningful changes; findings should therefore be considered preliminary.

CONCLUSION

Preliminary findings suggest that interdisciplinary interventions including acceptance-based approaches, psychoeducation, nutrition and lifestyle modification, delivered 1-year post-operative, are promising. Further scientific enquiry is warranted with well-designed studies and long-term follow-ups.

Preoperative and post-operative psychosocial interventions for bariatric surgery patients: A systematic review

Psychosocial interventions are increasingly being utilized to help patients prepare for, and adjust to changes following, bariatric surgery in order to optimize psychosocial adjustment and weight loss. The current systematic review examined the impact of preoperative and post-operative psychosocial interventions with a behavioural and/or cognitive focus on weight, dietary behaviours, eating pathology, lifestyle behaviours, and psychological functioning. A PsycINFO and Medline search of publications was conducted in March 2019. Two authors assessed retrieved titles and abstracts to determine topic relevance and rated the quality of included studies using a validated checklist. Forty-four articles (representing 36 studies) met the study inclusion criteria. The current evidence is strongest for the impact of psychosocial interventions, particularly cognitive behavioural therapy, on eating behaviours (eg, binge eating and emotional eating) and psychological functioning (eg, quality of life, depression, and anxiety). The evidence for the impact of psychosocial interventions on weight loss, dietary behaviours (eg, dietary intake), and lifestyle behaviours (eg, physical activity) is relatively weak and mixed. Psychosocial interventions can improve eating pathology and psychosocial functioning among bariatric patients, and the optimal time to initiate treatment appears to be early in the post-operative period before significant problematic eating behaviours and weight regain occur.

The effects of bariatric surgery on psychological aspects of eating behaviour and food intake in humans

Bariatric surgery has emerged as an increasingly popular weight loss intervention, with larger and more endurable weight loss compared to pharmacological and behavioural interventions. The degree of weight loss patients experience varies, between individuals, surgeries and over time. An explanation as to why differing weight loss trajectories exist post-surgery could be due to the complex interplay of individual differences in relation to eating behaviours and appetite. Thus the aim of this narrative review is to explore literature between 2008 and 2018, to assess the impact of impact of bariatric surgery on food selection and nutrient status, on eating behaviour traits and on disturbed and disordered eating behaviour, to determine their impact of weight loss success and weight loss trajectories. Immediately post-surgery, up until 1-2 years post-surgery, there is a reliance upon the surgery's alteration of the gastrointestinal tract to control food intake and subsequently lose weight. Energy intake is reduced, dietary adherence is higher, supplement intake is higher, appetite ratings are lower, there is a reduction in psychopathology, and an increase in wellbeing. After this point, patients become more susceptible to weight regain, as this is the point where passive observation of the weight reducing action of surgery, moves into more cognitive effort, on the part of the individual, to control energy intake. There are various factors which influence an individual's ability to successfully regulate their energy intake post-surgery, such as their level of Disinhibition, Restraint, Hunger, Emotional Eating, Uncontrolled Eating, psychopathology and wellbeing. The need for continued psychological and nutritional support post-surgery is necessary to reduce weight regain susceptibility.

Psychosocial Predictors of Response to Telephone-Based Cognitive Behavioural Therapy in Bariatric Surgery Patients

OBJECTIVE

Bariatric surgery is an empirically supported treatment for severe obesity; however, it does not directly target underlying behavioural and psychological factors that potentially contribute to obesity. Mounting evidence supports the efficacy of cognitive behavioural therapy (CBT) for improving eating psychopathology and psychological distress among bariatric patients, and telephone-based CBT (Tele-CBT) is a novel delivery method that increases treatment accessibility.

METHODS

This study aimed to identify demographic and clinical predictors of response to Tele-CBT among 79 patients who received Tele-CBT in 3 previous studies. Listwise deletion was applied, after which 58 patients were included in a multivariate linear regression adjusted for age, sex and education status, to evaluate patient rurality index (urban or nonurban), and baseline binge eating, emotional eating and depression symptoms, as predictors of tele-CBT response.

RESULTS

The predictors explained 31% of the observed variance [R²=0.312, F(4,57)=3.238, p<0.01]. Patient rurality index (beta=0.341, p<0.01) was the only statistically significant predictor of Tele-CBT response.

CONCLUSIONS

Given the limited psychosocial resources available in many bariatric surgery programs, the findings suggest that Tele-CBT may be particularly beneficial for patients residing in nonurban communities with limited access to other health-care services.

Telephone-based cognitive behavioural therapy for female patients 1-year post-bariatric surgery: A pilot study

OBJECTIVE

Although bariatric surgery is a durable treatment for patients with severe obesity, it does not directly address behavioural and psychological factors that potentially contribute to weight regain post-surgery. Psychological interventions, such as cognitive behavioural therapy (CBT), can be challenging to access due to physical limitations and practical barriers. Telephone-based CBT (Tele-CBT) can improve eating psychopathology and psychological distress before and after surgery. Given the frequent occurrence/recurrence of problematic eating-related and psychological issues many patients face 1-year post-surgery, this open-trial pilot study aimed to evaluate the effectiveness of Tele-CBT delivered 1-year post-surgery as an adjunctive treatment to the usual standard of bariatric care.

METHODS

Patients (n=43) received six 1-h Tele-CBT sessions delivered weekly beginning at 1-year post-surgery. Patients completed questionnaire packages before and after the intervention to assess changes in binge eating (BES), emotional eating (EES), depression (PHQ-9), and anxiety (GAD-7).

RESULTS

Thirty-two patients completed Tele-CBT yielding a 74.4% completion rate. Participants reported significant improvements on the Binge Eating Scale (t(31)=3.794, p=0.001), Emotional Eating Scale (t(31)=3.508, p=0.001), Patient Health Questionnaire-9 Item Scale (z=-2.371, p=0.018), and Generalised Anxiety Disorder-7 Item Scale (z=-3.546, p<0.001) immediately following Tele-CBT.

DISCUSSION

The results demonstrate that Tele-CBT delivered 1-year post-surgery may improve binge eating, emotional eating, depression, and anxiety. Additional research is warranted to examine whether these changes translate into long-term improvements in bariatric surgery outcomes.

A Pilot Study on Telephone Cognitive Behavioral Therapy for Patients Six-Months Post-Bariatric Surgery

OBJECTIVE

This study aimed to determine the feasibility and preliminary efficacy of a post-operative telephone-based cognitive behavioral therapy intervention (Tele-CBT) in improving eating pathology and psychosocial functioning.

METHODS

Six-month post-operative bariatric surgery patients (n = 19) received six sessions of Tele-CBT. Study outcome variables included binge eating (BES), emotional eating (EES), depressive symptoms (PHQ-9), and anxiety symptoms (GAD-7).

RESULTS

Retention was 73.7 % post-intervention. Tele-CBT resulted in significant reductions in mean difference scores on BES, EES-Total, EES-Anxiety, EES-Anger, PHQ9, and GAD7. Tele-CBT patients experienced a mean weight loss of 8.62 ± 15.02 kg between 6-months post-surgery (pre-Tele-CBT) and 12-months post-surgery.

CONCLUSIONS

These preliminary results suggest that post-surgery Tele-CBT is feasible and can improve post-surgery symptoms of psychopathology in this uncontrolled study, supporting the need for a randomized controlled trial.

Cognitive behavioral therapy and predictors of weight loss in bariatric surgery patients

PURPOSE OF REVIEW

Bariatric surgery is the most effective treatment for morbid obesity. However, 20-30% of patients undergoing bariatric surgery experience premature weight stabilization or weight regain postoperatively. We report on the recent literature of predictors of weight loss and the efficacy of cognitive behavioral therapy (CBT) in bariatric patients.

RECENT FINDINGS

Preoperative disordered eating behaviors do not appear to be significantly predictive of postoperative weight loss. Postoperative disordered eating behaviors, eating disorders, and depressive symptoms have been found to be associated with less optimal weight loss results. Recent studies show that CBT can contribute in reducing disordered eating behaviors and depressive symptoms. Some studies also show that pre and postoperative CBT interventions can promote weight loss. New applications of CBT such as by telephone, internet, or virtual reality might contribute to more accessible and low-cost treatments for the large group of bariatric patients worldwide.

SUMMARY

CBT seems to be effective in reducing risk factors for weight regain after bariatric surgery, such as disordered eating behavior and depression. Controlled studies with long-term follow-up and larger sample sizes are needed to investigate the long-term effect of CBT interventions on weight loss results and psychological well-being.

A Qualitative Analysis of Post-operative Nutritional Barriers and Useful Dietary Services Reported by Bariatric Surgical Patients

BACKGROUND

Outcomes studies show many bariatric patients fail to lose optimal weight or regain significant weight post-surgery. One reason for weight regain may be difficulty adhering to the postoperative diet.

METHODS

Cross-sectional survey methodology collected text data on perceived postoperative nutritional barriers and helpful dietary services reported by bariatric patients. Participants were solicited from an online obesity support website, and 440 responses related to perceived barriers and 330 responses regarding postoperative services were examined using inductive content analysis.

RESULTS

Barriers were categorized as being Internal, External, and None. Internal barriers were classified as Psychological, Physiological, and Psychophysiological, with Psychophysiological being the most commonly reported (85.9 %). Helpful services reported included categories of None, Provided, and On their Own. Sixty-two percent of participants reported receiving at least one Provided service that was helpful, including knowledge and support from professionals like registered dietitian nutritionists (RDNs). However, 22 % of participants reported seeking out at least one service On their Own such as through the Internet, and 27 % of participants reported not receiving or not using any helpful services.

CONCLUSIONS

The physiological nature of post-surgical changes and the mental stamina required of positive eating habits contribute to postoperative adherence difficulties. Many patients likely exhibit poor habits pre-surgery, and without added help to change these behaviors may regain weight. Participants in this study indicated that convenient access to an RDN was helpful. Bariatric facilities should include staff well-trained in the specific nutritional barriers patients face and provide availability of staff beyond the initial postoperative phase.

The relationship between eating psychopathology and obstructive sleep apnea in bariatric surgery candidates: A retrospective study

OBJECTIVE

Obstructive sleep apnea (OSA), eating psychopathology, and major depressive disorder (MDD) are highly prevalent in patients with severe obesity. Our study aimed to identify differences in binge-eating disorder (BED) prevalence in bariatric surgery candidates with and without OSA.

METHODS

In this retrospective study, demographic data, psychiatric diagnoses, OSA diagnosis, binge eating, depressive and quality of life (QOL) symptoms were collected from 1,099 bariatric surgery candidates from a Canadian setting. Analysis of variance was used to identify differences in psychopathology and QOL between groups with OSA and BED, BED alone, OSA alone or neither BED or OSA.

RESULTS

Study participants' mean body mass index was 49.3 kg/m² and 52.6% had a diagnosis of OSA. Patients with OSA were significantly more likely to have a diagnosis of past BED (χ²  = 6.848, p = .009) and current MDD (χ²  = 5.165, p = .023). Binge-eating (p < .001) and depressive symptoms (p < .001) were significantly higher in patients with co-morbid BED and OSA compared to patients with OSA alone or patients with no diagnosis of BED or OSA. Patients with co-morbid BED and OSA only had significantly lower physical (p < .001) and mental QOL (p = .007) compared to patients with no diagnosis of BED or OSA.

DISCUSSION

Our findings suggest that patients with a history of BED should be reassessed for OSA. Research is needed to examine whether BED may predispose individuals to developing obesity and OSA.

Analysis of the Information Quality of Bariatric Surgery Smartphone Applications Using the Silberg Scale

There is a paucity of literature that has evaluated the information quality of the current bariatric and obesity applications. Our objective was to evaluate the quality of currently available smartphone applications for bariatric-patient care using the Silberg scale. The two most widely used smartphone application online stores were searched in June 2014 and a total of 39 applications were evaluated. The average Silberg score of the 39 applications was 4.0 ± 1.76. The current gaps of information quality include the lack of provision of appropriate references, full disclosure of sponsorship, and accurate disclosure whether the application has been modified in the past month.

A pilot randomized controlled trial examining the feasibility, acceptability, and efficacy of Adapted Motivational Interviewing for post-operative bariatric surgery patients

OBJECTIVE

Non-adherence to post-operative dietary guidelines contributes to poorer outcomes following bariatric surgery. The current pilot study evaluated the impact of Adapted Motivational Interviewing (AMI) on patients' readiness for change, self-efficacy, and adherence to dietary guidelines following bariatric surgery.

METHODS

A randomized wait-list controlled trial was conducted. Post-operative bariatric patients (N=51) were randomly allocated to receive the single session AMI intervention either immediately (AMI group; n=23), or in 12weeks while continuing to receive standard bariatric care (wait list control [WLC] group; n=28).

RESULTS

Completer analyses (n=44) indicated that participants reported improvements in readiness, confidence, and self-efficacy for change immediately following the AMI intervention. They also reported improvements in binge eating symptomatology and some measures of dietary adherence across the 12-week follow-up period. Significant Group×Time interactions for confidence for change, dietary adherence, and binge eating symptomatology suggest that the AMI group improved on these outcomes whereas the control group did not.

CONCLUSIONS

These preliminary findings suggest that AMI is an acceptable and feasible intervention with the potential to improve bariatric patients' confidence for change and eating behaviors. Future research should examine these results in comparison to routinely collected postsurgery follow-up data to learn more about AMI's efficacy for improving post-surgical adherence.

A pilot randomized controlled trial of telephone-based cognitive behavioural therapy for preoperative bariatric surgery patients

BACKGROUND

Psychosocial interventions can improve eating behaviours and psychosocial functioning in bariatric surgery candidates. However, those that involve face-to-face sessions are problematic for individuals with severe obesity due to mobility issues and practical barriers.

OBJECTIVE

To examine the efficacy of a pre-operative telephone-based cognitive behavioural therapy (Tele-CBT) intervention versus standard pre-operative care for improving eating psychopathology and psychosocial functioning.

METHODS

Preoperative bariatric surgery patients (N = 47) were randomly assigned to receive standard preoperative care (n = 24) or 6 sessions of Tele-CBT (n = 23).

RESULTS

Retention was 74.5% at post-intervention. Intent-to-treat analyses indicated that the Tele-CBT group reported significant improvements on the Binge Eating Scale (BES), t (22) = 2.81, p = .01, Emotional Eating Scale (EES), t (22) = 3.44, p = .002, and Patient Health Questionnaire-9 (PHQ-9), t (22) = 2.71, p = .01, whereas the standard care control group actually reported significant increases on the EES, t (23) = 4.86, p < .001, PHQ-9, t (23) = 2.75, p = .01, and General Anxiety Disorder-7 (GAD-7), t (23) = 2.93, p = .008 over the same time period.

CONCLUSIONS

Tele-CBT holds promise as a brief intervention for improving eating psychopathology and depression in bariatric surgery candidates.
