Efficacy of Telephone-Based Cognitive Behavioral Therapy for Weight Loss, Disordered Eating, and Psychological Distress After Bariatric Surgery: A Randomized Clinical Trial.

Importance: Weight regain after bariatric surgery is associated with recurrence of obesity-related medical comorbidities and deterioration in quality of life. Developing efficacious psychosocial interventions that target risk factors, prevent weight regain, and improve mental health is imperative. Objective: To determine the efficacy of a telephone-based cognitive behavioral therapy (tele-CBT) intervention at 1 year after bariatric surgery in improving weight loss, disordered eating, and psychological distress. Design, Setting, and Participants: This multisite randomized clinical trial was conducted at 3 hospital-based bariatric surgery programs, with recruitment between February 2018 and December 2021. Eligibility for participation was assessed among 314 adults at 1 year after bariatric surgery who were fluent in English and had access to a telephone and the internet. Patients with active suicidal ideation or poorly controlled severe psychiatric illness were excluded. Primary and secondary outcome measures were assessed at baseline (1 year after surgery), after the intervention (approximately 15 months after surgery), and at 3-month follow-up (approximately 18 months after surgery). Data were analyzed from January to February 2023. Interventions: The tele-CBT intervention consisted of 6 weekly 1-hour sessions and a seventh booster session 1 month later. The control group received standard postoperative bariatric care. Main Outcomes and Measures: The primary outcome was postoperative percentage total weight loss. Secondary outcomes were disordered eating (Binge Eating Scale [BES] and Emotional Eating Scale [EES]) and psychological distress (Patient Health Questionnaire-9 item scale [PHQ-9] and Generalized Anxiety Disorder-7 item scale [GAD-7]). The hypotheses and data-analytic plan were developed prior to data collection. Results: Among 306 patients 1 year after bariatric surgery (255 females [83.3%]; mean [SD] age, 47.55 [9.98] years), there were 152 patients in the tele-CBT group and 154 patients in the control group. The group by time interaction for percentage total weight loss was not significant (F1,160.61 = 2.09; P = .15). However, there were significant interactions for mean BES (F2,527.32 = 18.73; P < .001), EES total (F2,530.67 = 10.83; P < .001), PHQ-9 (F2,529.93 = 17.74; P < .001), and GAD-7 (F2,535.16 = 15.29; P < .001) scores between the tele-CBT group and control group across all times. Conclusions and Relevance: This study found that tele-CBT delivered at 1 year after surgery resulted in no change in short-term weight outcomes but improved disordered eating and psychological distress. The impact of these psychosocial improvements on longer-term weight outcomes is currently being examined as part of this longitudinal multisite randomized clinical trial.

Self-Compassion May Have Benefits for Body Image among Women with a Higher Body Mass Index and Internalized Weight Bias.

Negative attitudes towards one's own body are common among women and are linked to adverse consequences including negative affect, low self-esteem, and eating pathology. Self-compassion has been found effective in improving body image; however, few published studies have examined self-compassion in populations with higher BMIs despite the positive correlation between weight and body dissatisfaction. The current study examined the efficacy of a self-compassion letter-writing exercise versus two active control groups in response to a negative body image induction. The sample of college-aged females (M age = 20.91 years; SD = 5.47) was split between higher and lower BMI to determine whether self-compassion affects body image, affect, and self-esteem differently across weight groups. Weight bias internalization (WBI: i.e., internalization of society's negative stigma against those with higher BMIs) was examined as a moderator of this relationship in the higher BMI group. Results suggest that letter writing improved body image regardless of condition (p < 0.001). The self-compassion exercise promoted more adaptive body image (p = 0.007) and self-compassion (p = 0.013) than one control condition for those with high WBI. Results suggest that self-compassion can be helpful in ameliorating negative body image for females of all sizes, and that levels of WBI may alter the effect of body image interventions.

Mental health outcomes in revisional versus primary bariatric surgery patients: A matched case control study.

OBJECTIVE: To determine whether depression and anxiety symptoms differ between revisional bariatric surgery patients and primary bariatric surgery patients, as such mental health outcomes can have long-lasting impacts on weight loss and the overall success of bariatric surgery. METHODS: An exploratory matched case control study was performed with a total of 50 patients - 25 patients who had received revisional surgery and 25 who had received primary bariatric surgery. Revisional patients were matched with primary patients on sex, age (±7 years), pre-operative BMI (±8.0) and time since surgery. Mental health outcomes of depressive and anxiety symptoms, as measured by the Patient Health Questionnaire 9-Item scale (PHQ-9) and Generalized Anxiety Disorder 7-Item scale (GAD-7) respectively, were compared between groups. RESULTS: No significant differences were found between the revisional and primary bariatric surgery groups across time (pre-surgery, 1-year post-surgery, 2-year post-surgery and 3-years post-surgery) for GAD-7 (f = 0.045, p = 0.987) and PHQ-9 (f = 0.277, p = 0.842) scores. CONCLUSION: Primary and revisional bariatric surgery patients do not have significant differences in depressive and anxiety scores. Revisional bariatric surgery can thus be effective in the remission of comorbid mental health conditions as trajectories remain comparable up to 3-years following surgery.

A mixed methods investigation of reasons underlying fear of positive evaluation.

Fear of negative evaluation (FNE) is a hallmark feature of social anxiety disorder (SAD). There is also evidence that people with SAD fear receiving positive evaluation and that fear of positive evaluation (FPE) is distinct from FNE. However, researchers have speculated that concerns related to negative evaluation may actually underlie FPE. This study sought to advance our understanding of FPE by employing both quantitative and qualitative methods to assess the reasons underlying participants' endorsement of FPE on the Fear of Positive Evaluation Scale and the extent to which these reasons reflect FNE versus FPE in a sample of individuals with SAD (n = 47) and a nonclinical comparison group (n = 49). Results indicated that responses to the FPES items primarily reflected an underlying FNE. Consistent with contemporary cognitive-behavioural theories of SAD, fear of proximal or eventual negative judgement emerged as the most common reason for participants' responses on the FPES. However, participants reported other reasons that did not reflect FNE, such as fear of hurting people's feelings and uncertainty associated with positive evaluation. All of the reasons underlying participants' ratings on the FPES were reported by both the SAD group and the nonclinical comparison group; however, individuals with SAD endorsed each of the reasons to a greater extent. These findings suggest that the FPES does not exclusively assess FPE as intended; however, the emergence and endorsement of reasons other than FNE suggest that FPE exists as a distinct construct.

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. TRIAL REGISTRATION NUMBER: NCT05258578.

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.

Coping during COVID-19: The Impact of Cognitive Appraisal on Problem Orientation, Coping Behaviors, Body Image, and Perceptions of Eating Behaviors and Physical Activity during the Pandemic.

Large surveys indicate that many people perceive that their health behaviors (i.e., eating behaviors, physical activity, and self-care routines) and body image have changed during COVID-19; however, large individual variation exists. A person's cognitive appraisal of COVID-19 disruptions may help account for individual differences. Those with a negative problem orientation perceive problems as "threats", whereas those with a positive problem orientation reframe problems as "opportunities". The present experimental study examined the impact of appraisals, specifically being prompted to reflect on the changes in health routines precipitated by COVID-19 restrictions as either "threats" or "opportunities", on problem orientation, coping behaviours, body image, and perceptions of eating behaviors and physical activity in a sample of female undergraduate students (N = 363). The group that reflected on challenges/barriers reported having a more negative problem orientation, being more negatively impacted by COVID-19, engaging in more maladaptive coping behaviors, and having less positive body image compared to participants who reflected on opportunities presented during the pandemic. Findings suggest that appraisals and problem orientation are malleable, and that people who tend to fixate on the challenges associated with COVID-19 may benefit from strategically reflecting on their own resilience and new opportunities that have arisen for engaging in health behaviors.

Understanding bariatric patients' experiences of self-management post-surgery: A qualitative study.

Although most bariatric patients achieve significant weight loss and improvements in both physical and mental health-related quality of life (HRQoL) in the short-term, there is wide variability in weight and long-term HRQoL outcomes. The role of bariatric patients' self-management style in explaining variability in long-term outcomes is unclear. This qualitative study examined bariatric patients' self-management experiences after bariatric surgery in relation to long-term outcomes. A qualitative study was conducted using semi-structured individual interviews with post-surgery patients (n = 23) at a Canadian bariatric surgery program. A constant comparative approach was used to systematically analyse the data and identify overarching themes. Variation in patients' experiences and follow-up time were the two primary units of analysis. Patients were predominantly female (n = 19; 82.6%) and had a mean age of 50 ± 8.49 years. The median time post-surgery was 2 years (range: 6 months-7 years). Three distinct phases described the process of self-management post-bariatric surgery: (1) rediscovering self-esteem and confidence in one's ability to self-manage (1-month to 1.5-years post-surgery), (2) achieving weight maintenance and addressing emotion dysregulation (1.5-3-years post-surgery) and (3) embracing a flexible balanced lifestyle (beyond 3-years). Bariatric surgery patients experience distinct challenges relative to their post-surgery time course. Facilitating access to interprofessional bariatric care after surgery allowed patients to acquire the self-management knowledge and skills necessary to address challenges to following the bariatric guidelines in the long-term.

The effect of a food addiction explanatory model of eating behaviours on weight-based stigma: An experimental investigation.

Weight stigmatization and discrimination are pervasive issues that have numerous adverse consequences for those with excess weight. It has been proposed that some individuals may be addicted to hyperpalatable processed foods, resulting in weight promoting eating behaviours. The current study replicated and extended a study examining the effect of a food addiction explanation for eating behaviours on weight-based stigma and weight-controllability beliefs. Undergraduate students (N = 757) were randomly assigned to one of four conditions where they read a newspaper article accompanied by a photo of a woman 1) who was either of a higher body mass index (BMI) or a lower BMI, and 2) that attributed her eating behaviours to either food addiction or poor dietary and lifestyle choices. Stigma towards the woman and individuals with a higher BMI in general were assessed. Results indicated that the woman with a higher BMI elicited greater weight stigma. Attributing weight to food addiction increased perceptions of psychopathology towards the woman, whereas attributing weight to poor dietary and lifestyle choices elicited judgment towards the woman. Neither explanation about eating behaviours elicited stigma towards individuals with a higher BMI in general. Findings suggest that a food addiction explanation alone may not be sufficient to reduce weight stigma.

The impact of COVID-19 pandemic on bariatric patients' self-management post-surgery.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has had far reaching consequences on the health and well-being of the general public. Evidence from previous pandemics suggest that bariatric patients may experience increased emotional distress and difficulty adhering to healthy lifestyle changes post-surgery. OBJECTIVE: We aimed to examine the impact of the novel COVID-19 public health crisis on bariatric patients' self-management post-surgery. METHOD: In a nested-qualitative study, semi-structured telephone interviews were conducted with 23 post-operative bariatric patients who had undergone Roux-en-Y gastric bypass (RYGB) at a Canadian Bariatric Surgery Program between 2014 and 2020. A constant comparative approach was used to systematically analyze the data and identify the overarching themes. RESULTS: Participants (n = 23) had a mean age of (48.82 ± 10.03) years and most were female (n = 19). The median time post-surgery was 2 years (range: 6 months-7 years). Themes describing the impact of COVID-19 pandemic on patients' post-bariatric surgery self-management included: coping with COVID-19; vulnerability factors and physical isolation; resiliency factors during pandemic; and valuing access to support by virtual care. The need for patients to access post-operative bariatric care during COVID-19 differed based on gender and socioeconomic status. CONCLUSION: This study showed that the COVID-19 pandemic has impacted patients' ability to self-manage obesity and their mental health in a variety of ways. These findings suggest that patients may experience unique psychological distress and challenges requiring personalized care strategies to improve obesity self-care and overall well-being.

"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.

The Bariatric Interprofessional Psychosocial Assessment of Suitability Scale predicts binge eating, quality of life and weight regain following bariatric surgery.

Presurgical psychosocial evaluations are an important component of bariatric care; yet, bariatric programs vary widely in their assessment and interpretation of psychosocial risk. There is a need for validated clinical tools that help to standardize and streamline the assessment of variables relevant to surgical outcomes. The present study contributes to the validation of the Bariatric Interprofessional Psychosocial Assessment of Suitability Scale (BIPASS), a novel presurgical psychosocial evaluation tool, by: (a) examining the psychometric properties and optimal cutoff score, and; (b) examining the ability of the BIPASS tool to predict outcomes 1 and 2 years postsurgery, including weight regain, quality of life, psychiatric symptoms and adherence to postsurgical follow-up appointments. The BIPASS was applied retrospectively to the charts of 179 consecutively referred patients to a metropolitan bariatric surgery programme. Internal consistency for the BIPASS was acceptable, and interrater reliability was excellent. Higher BIPASS scores predicted higher binge eating symptomatology and lower mental health-related quality of life at 1 year postsurgery, and weight regain at 2 years (all P < .01). The BIPASS did not predict adherence to postsurgical follow-up appointments. Findings suggest that the BIPASS can be used to identify patients at increased risk of disordered eating, poor quality of life and weight regain early in the postsurgical course, thereby facilitating patient education and appropriate interventions.

Effect of Increasing the Dietary Protein Content of Breakfast on Subjective Appetite, Short-Term Food Intake and Diet-Induced Thermogenesis in Children.

Dietary protein affects energy balance by decreasing food intake (FI) and increasing energy expenditure through diet-induced thermogenesis (DIT) in adults. Our objective was to investigate the effects of increasing the dietary protein in an isocaloric breakfast on subjective appetite, FI, blood glucose, and DIT in 9-14 y children. Two randomized repeated measures designs were used. In experiment 1, 17 children (9 boys, 8 girls) consumed isocaloric meals (450 kcal) on four separate mornings containing: 7 g (control), 15 g (low protein, LP), 30 g (medium protein, MP) or 45 g (high protein, HP) of protein. Blood glucose and subjective appetite were measured at baseline and regular intervals for 4 h, and FI was measured at 4 h. In experiment 2, 9 children (6 boys, 3 girls) consumed the control or HP breakfast on two separate mornings, and both DIT and subjective appetite were determined over 5 h. In experiment 1, all dietary protein treatments suppressed subjective appetite compared to control (p < 0.001), and the HP breakfast suppressed FI compared with the LP breakfast and control (p < 0.05). In experiment 2, DIT was higher after HP than control (p < 0.05). In conclusion, increasing the dietary protein content of breakfast had favorable effects on satiety, FI, and DIT in children.

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.

Psychiatric Management of Bariatric Surgery Patients: A Review of Psychopharmacological and Psychological Treatments and Their Impact on Postoperative Mental Health and Weight Outcomes.

BACKGROUND: Bariatric surgery is an effective treatment for severe obesity; however, high rates of psychiatric comorbidity complicate bariatric surgery care. As a result, importance has been placed on the need for ongoing psychiatric support in patients undergoing bariatric surgery. Given the lack of conclusive presurgery psychosocial predictors of postoperative mental health outcomes, studies have now shifted their focus to understand the long-term psychosocial sequalae that arise after surgery. Increasing evidence has demonstrated the potential for psychiatric care to stabilize psychiatric symptoms and minimize patient distress. OBJECTIVE: To review psychopharmacological and psychological interventions for patients undergoing bariatric surgery and their impact on mental health and weight outcomes after surgery. METHODS: We performed a comprehensive literature search in Ovid MEDLINE for studies examining the impact of psychopharmacological and psychological treatments on bariatric patients' postoperative mental health and weight outcomes. RESULTS: Overall, 37 studies were included in the review. Preliminary evidence suggests that psychiatric medications do not negatively impact weight loss or health-related quality of life in the short term; however, more rigorous research designs are needed. There are insufficient data on specific psychiatric medications and long-term impact on weight loss and psychosocial outcomes. Postoperative psychological interventions have evidence for improving eating psychopathology, anxiety, and depressive symptoms; however, effects on weight loss remain unclear. CONCLUSION: Evidence for psychopharmacological and psychological treatments remains preliminary. Consideration should be given to integrated, stepped-care models to provide personalized psychiatric interventions after surgery. Future research on expanding current psychiatric interventions, timing of delivery, and predictors of response is needed.

The Impact of Coronavirus Disease 2019 on Bariatric Surgery: Redefining Psychosocial Care.

The global outbreak of the 2019 novel coronavirus disease has had a tremendous psychological impact on individuals around the world. Individuals with obesity are susceptible to distress and psychological sequalae secondary to this pandemic, which can have detrimental effects on obesity management. In particular, individuals undergoing bariatric surgery could experience increased emotional distress, resulting in increased eating psychopathology, mental health exacerbation, and difficulties with self-management. Addressing these challenges requires novel approaches to redefining psychosocial care before and after bariatric surgery. Emerging evidence suggests that the remote delivery of care using virtual care models, including mobile and online modalities, could extend the reach of psychosocial services to individuals after bariatric surgery and mitigate weight regain or impairment in quality of life. Because of this pandemic, the rapid integration of virtual psychosocial care in bariatric surgery programs to address patients' needs will create new opportunities for clinical and implementational scientific research.

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.

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.
