Remote assessments and behavioral interventions in post-bariatric surgery patients.

Sustained weight loss and health improvements after bariatric surgery require long-term monitoring and, for a significant minority of patients, postoperative intervention. Unfortunately, many patients demonstrate difficulty engaging in long-term follow-up and treatment due to time restrictions, geographic limitations, and financial burden. Conducting assessments and interventions remotely may help to mitigate these barriers, allowing for greater access to care and improved outcomes. This review will summarize the results of research using remote methods to conduct assessments and implement interventions with patients after bariatric surgery. Benefits and challenges of implementing these approaches will be highlighted, and future directions in this area will be discussed.

Measurement of adherence in bariatric surgery: a systematic review.

After bariatric surgery, rates of adherence to behavioral recommendations, including attending regular appointments and following specific dietary, physical activity, and vitamin use recommendations, tend to be highly variable across studies. Lack of consistency in measurement of adherence is a likely contributor to this variability, making it challenging to determine the prevalence and impact of nonadherence in this population. PubMed was searched for articles measuring behavioral adherence or compliance in patients after bariatric surgery, resulting in 85 articles. Articles were reviewed for the definition and measurement of adherence in each area (appointment attendance, as well as dietary, physical activity, and vitamin use adherence), and on the use and reporting of recommended adherence measurement strategies. Over half of the articles measured adherence to appointment attendance. Significant variability was found across adherence definitions and measurement methods, and use of recommended adherence measurement strategies was poor. Adherence was mostly commonly measured via self-report (either verbal or written) using cutoffs for adherent versus nonadherent behavior. Over half of studies assessed adherence up to ≥2 years postsurgery. Recommendations for ways to improve adherence measurement in patients who have had bariatric surgery are outlined.

Managing severe obesity: understanding and improving treatment adherence in bariatric surgery.

Severe obesity (body mass index ≥40 kg/m2) is a chronic disease that is associated with significantly increased risk of serious and chronic health problems as well as impaired quality of life. For those with severe obesity, bariatric surgery is the most effective treatment for significant and long-term weight loss and resolution of comorbid medical conditions, particularly diabetes. Long-term success is thought to depend to some degree on the patient's ability to adhere to a complex set of behaviors, including regular attendance at follow up appointments and following stringent dietary, exercise, and vitamin recommendations. Here, we summarize the current research on behavioral adherence in patients with severe obesity presenting for bariatric surgery and we highlight challenges and make recommendations for improved self-management before and after surgery.

Getting personal: a review of sexual functioning, body image, and their impact on quality of life in patients with inflammatory bowel disease.

BACKGROUND: Inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, is a chronic relapsing disorder associated with distressing physical and psychological symptoms. Many patients with IBD have impaired quality of life. Sexual functioning and body image are rated high among concerns of patients with IBD and may impact quality of life. A better understanding of the roles of sexual functioning and body image in quality of life for patients with IBD is needed because improvement in quality of life is a primary therapeutic goal. The aim of this review was to summarize the current literature on sexual functioning and body image in patients with IBD, emphasizing their impact on quality of life. METHODS: An electronic search of the literature was conducted using the PubMed, PsycINFO, and Cochrane databases. Key phrases included: "Ulcerative Colitis/Crohn's disease/Inflammatory Bowel Disease and sexual function," and "Ulcerative Colitis/Crohn's disease/Inflammatory Bowel Disease and body image." The search produced 1284 citations. We identified 56 studies, which were conducted from 1990 through April 2014, written in English, and included at least 10 adults with IBD. CONCLUSIONS: Few studies have tested directly the association between quality of life and sexual functioning and body image among patients with IBD. Results preliminarily suggest a positive relationship between quality of life and sexual functioning and body image postoperatively among patients with IBD. Future studies comprised of patients who have not had surgery are necessary to better understand the relationship between sexual functioning, body image, and quality of life in patients with active and inactive IBD.

Factor structure and predictive utility of the Binge Eating Scale in bariatric surgery candidates.

BACKGROUND: Screening for binge eating before bariatric surgery is a component of the recommended clinical practice for bariatric surgery candidates. The Binge Eating Scale (BES) is 1 of the most commonly used self-report measures of eating behaviors in preoperative evaluations; however, the factor structure of this measure has not been evaluated in the bariatric population. The aims of the present study were to report the mean, standard deviation, and reliability of the BES for patients seeking bariatric surgery; to evaluate the 2-factor structure of the BES using confirmatory factor analysis; and to investigate the association between the BES and its factors with surgical weight loss. The setting was an academic medical center. METHODS: A total of 530 patients completed the BES as a component of their psychological evaluation before undergoing Roux-en-Y gastric bypass surgery. RESULTS: Approximately one third of patients reported at least mild to moderate binge eating, with 9% of patients reporting severe binge eating on the BES. The BES demonstrated good internal consistency. The results of the confirmatory factor analysis indicated that a 2-factor structure, consisting of feelings/cognitions related to binge eating and behavioral manifestations of binge eating, was the best fit to the data. Nonsignificant correlations were found between the BES and its 2 factors with short-term postoperative weight loss. CONCLUSION: The BES measures 2 aspects of binge eating in bariatric surgery candidates, feelings/cognitions and behavioral manifestations of binge eating. Consideration of these factors in patients presenting for bariatric surgery could allow for a more detailed understanding of binge eating in this population.

Examining the Binge Eating Scale in screening for binge eating disorder in bariatric surgery candidates.

BACKGROUND: This study assessed the utility of the Binge Eating Scale (BES) as a measure of binge eating disorder (BED) in a bariatric surgery-seeking population by (a) determining the optimal BES cut score for predicting BED, (b) calculating concordance statistics, and (c) determining the predictive value of each BES item. METHODS: Four hundred seventy-three patients presented for a psychological evaluation prior to Roux-en-Y gastric bypass surgery. The BES and the SCID semi-structured interview for BED were administered. RESULTS: Receiver operating characteristic curve analyses identified an optimal BES cut score of 17, which correctly classified 78% of patients with BED. A cut score of 27 improved this statistic, but significantly increased the number of false negatives, which is undesirable for a screening assessment. Discriminant function analyses revealed that nearly all BES items significantly predicted BED. CONCLUSIONS: The BES is a valid screener of BED for patients seeking bariatric surgery; however, false positives can be expected. Administering the BES as part of a comprehensive psychological evaluation can help improve the assessment and treatment of patients presenting for bariatric surgery.

Confirmatory factor analysis of the Beck Depression Inventory-II in bariatric surgery candidates.

Screening for depression is an integral part of psychological evaluations conducted prior to bariatric surgery. The Beck Depression Inventory-II (BDI-II) is the most commonly used measure of depression in these treatment evaluations. The reliability and validity of the BDI-II has not yet been evaluated within bariatric surgery-seeking samples, evidencing a significant gap in the present literature. The purpose of the present study is to evaluate the structural validity of the BDI-II and to examine the reliability and convergent and criterion validity of this instrument within a bariatric surgery-seeking sample. The study population consisted of 505 ethnically diverse bariatric surgery candidates presenting for presurgical psychological evaluations in a midwestern urban academic medical center. Confirmatory factor analytic results indicated that a 3-factor model consisting of affective, cognitive, and somatic factors was the best fitting model of depression within this sample. Internal consistency reliability was satisfactory for each subscale, ranging from .72 to .82. Moderate to large correlations were observed between each BDI-II subscale and a measure of depression previously validated with bariatric surgery candidates indicating adequate convergent validity. On the basis of clinical interview, 14% of the sample was diagnosed with current major depression. Significant mean differences were observed between depressed and nondepressed patients with respect to each BDI-II subscale score, demonstrating criterion-related validity. The BDI-II is a reliable and valid measure of depression for bariatric surgery candidates. Understanding the factor structure of the BDI-II can be useful for planning potential presurgical psychological interventions.

Revisiting the revised master questionnaire for the psychological evaluation of bariatric surgery candidates.

BACKGROUND: This study aims to evaluate the Revised Master Questionnaire (MQR), a measure of cognitive and behavioral difficulties related to weight management, for use in bariatric surgery evaluations. The MQR's five domains include stimulus control, hopelessness, motivation, physical attribution, and energy balance knowledge, all of which are relevant to bariatric surgery evaluation. METHODS: Participants were 790 bariatric surgery candidates presenting for psychological evaluation in an urban medical center. Internal consistency reliability analyses were performed on the overall scale and subscales. Confirmatory factor analysis using principal components analysis was performed and the results compared with the original behavioral weight loss sample. Convergent validity with the Beck Depression Inventory (BDI) and Binge Eating Scale (BES) were evaluated. Differences in normative data for subgroups of the bariatric sample (by obesity category and by surgery type) were also evaluated. RESULTS: Alpha coefficients and mean inter-item correlations were largely acceptable and similar to the original behavioral weight loss sample. Factor analyses supported the consistency of the underlying factor structure. Convergent validity between the BDI and BES and relevant subscales was obtained. Overall, bariatric surgery candidates had significantly more adaptive scores than behavioral weight loss patients on three of the five scales; however, scores on physical attribution and energy balance knowledge were significantly lower. Candidates for gastric banding surgery had significantly more adaptive scores on all five subscales than candidates for gastric bypass surgery. CONCLUSIONS: The MQR evaluates important but under-assessed weight control-related constructs and has acceptable psychometric properties. Based on these findings, it is recommended for use as a component of the psychological evaluation for bariatric surgery.

Do patients seeking laparoscopic adjustable gastric banding surgery differ from those seeking gastric bypass surgery? A comparison of psychological profiles across ethnic groups.

BACKGROUND: Understanding presurgical psychological functioning is important in determining whether patients may benefit from psychological support before or after undergoing bariatric surgery. However, few studies have directly explored whether presurgical psychosocial profiles differ for patients presenting for different bariatric surgeries and what, if any, impact ethnic background might have. The present study compared presurgical depressive symptomatology, binge eating symptoms, and psychopathology in Caucasian and African American laparoscopic adjustable gastric banding (LAGB) and gastric bypass (RYGB) patients. METHODS: Patients (n=272) presenting for either LAGB or RYGB surgery completed self-report measures of depressive symptomatology (BDI), binge eating symptoms (BES), and psychopathology/personality (PAI) as part of the presurgical psychological evaluation. RESULTS: RYGB patients endorsed more depressive symptomatology, binge eating symptoms, somatic complaints, and antisocial features than LAGB patients, though higher BMI in the RYGB patients accounted for differences in binge eating symptoms. When the sample was examined by ethnic group, LAGB-RYGB differences were found only in African American, and not Caucasian, patients. CONCLUSIONS: Psychosocial profiles appear to differ for African American patients presenting for LAGB and RYGB surgeries; however, some of these differences are accounted for by differences in presurgical BMI. Gaining a better understanding of the initial psychological characteristics of bariatric surgery candidates may improve clinicians' abilities to identify and address specific areas of concern for these patients.

A survey of psychological assessment on interdisciplinary craniofacial teams.

OBJECTIVE: To explore the role of mental health professionals on craniofacial teams and determine how craniofacial teams assess for psychological concerns in their patient populations. DESIGN: Online and paper surveys. PARTICIPANTS: A total of 55 craniofacial team coordinators and 40 mental health professionals who are team members participated in this study. RESULTS: Results indicated that teams in 2007 generally viewed psychological services on their teams similarly to teams assessed in 1987. Most teams do not use formal measures in their assessment of psychological concerns, and they provide feedback via discussions with the families. Mental health professionals assess a wide variety of potential areas of concern and are generally satisfied with the referral sources available to their patients. CONCLUSIONS: Craniofacial teams appear to practice in a manner consistent with professional standards, and these teams seem to value the inclusion of mental health professionals as part of the interdisciplinary team. Implications and limitations including response rate are discussed.
