Sustained effects of a psychoeducational group intervention following bariatric surgery: follow-up of the randomized controlled BaSE study.

BACKGROUND: Evidence regarding the efficacy of psychosocial interventions after bariatric surgery is rare and shows conflicting results. OBJECTIVES: The Bariatric Surgery and Education (BaSE) study aimed to assess the efficacy of a psychoeducational group intervention in patients after bariatric surgery. SETTING: The BaSE study was a randomized, controlled, multicenter clinical trial involving 117 patients who underwent bariatric surgery. Patients received either conventional postsurgical visits or, in addition, a 1-year psychoeducational group program. The present study evaluated the sustained effects of the intervention program. Mean follow-up duration was 37.9 months (standard deviation [SD] 8.2 months) after surgery. METHODS: Outcome measures were as follows: body mass index (BMI), weight loss, self-efficacy, depression severity, and health-related quality of life (HRQOL). Groups were compared using an intention-to-treat approach with a mixed model for repeated measurements. RESULTS: A total of 74 patients (63.2%) completed the follow-up (T5) assessment. Mean weight loss for all patients was 43 kg (SD 15.5 kg) at T5 (mean BMI 35.1 kg/m2). Mean excess weight loss was 60.4%. The effects of the surgery during the first postsurgical year were reflected, on average, by both decreasing weight and psychosocial burden. At the T5 time point, patients had slowly started to regain weight and to deteriorate regarding psychosocial aspects. However, at T5, patients who had participated in the intervention program (n = 39) showed significantly lower depression severity scores (p = .03) and significantly higher self-efficacy (p = .03) compared to the control group (n = 35). The 2 groups did not differ regarding weight loss and quality of life. CONCLUSION: Psychoeducational intervention shows sustained effects on both depression severity scores and self-efficacy.

A 1-year videoconferencing-based psychoeducational group intervention following bariatric surgery: results of a randomized controlled study.

BACKGROUND: For severely obese patients, bariatric surgery has been recommended as an effective therapy. OBJECTIVES: The Bariataric Surgery and Education (BaSE) study aimed to assess the efficacy of a videoconferencing-based psychoeducational group intervention in patients after bariatric surgery. SETTING: The BaSE study is a randomized, controlled multicenter clinical trial involving 117 patients undergoing bariatric surgery (mean preoperative body mass index [BMI] 49.9 kg/m(2), SD 6.4). Patients were enrolled between May 2009 and November 2012 and were randomly assigned to receive either conventional postsurgical visits or, in addition, a videoconferencing-based 1-year group program. METHODS: Primary outcome measures were weight in kilograms, health-related quality of life (HRQOL), and general self-efficacy (GSE). Secondary outcome measures were depression symptoms and eating behavior. RESULTS: 94% of the patients completed the study. Mean weight loss for all patients was 45.9 kg (SD 16.4) 1 year after surgery (mean excess weight loss [EWL] 63%). Intention-to-treat analyses revealed no differences in weight loss, EWL, HRQOL, or self-efficacy between study groups at 1 year after surgery. However, patients with clinically significant depression symptoms (CSD) at baseline assigned to the intervention group (n = 29) had a significantly better HRQOL (P = .03), lower depression scores (P = .02), and a trend for a better EWL (.06) 1 year after surgery compared with the control group (n = 20). CONCLUSION: We could not prove the efficacy of the group program for the whole study sample. However, results indicate that the intervention is effective for the important subgroup of patients with CSD.

Translation and validation of the German version of the weight self-stigma questionnaire (WSSQ).

The experience of stigmatization is widespread among obese patients. The aim of the present study was to translate the English version of the weight self-stigma questionnaire (WSSQ) into German and to evaluate the psychometric properties of the German version in a sample of severely obese persons. Between March and June 2013, in the Outpatient Department of Obesity, University Hospital Heidelberg, 94 obese patients were recruited consecutively. A comprehensive questionnaire was completed by the participants. Significant correlations between WSSQ scores and mental quality of life, weight-related quality of life, depression, shame, guilt, and psychological distress all demonstrated the construct validity of the German version of the WSSQ. Patients with a BMI ≥ 50 showed a significantly higher self-stigma compared to patients with a BMI between 35 and 50.

Body image after sleeve gastrectomy: reduced dissatisfaction and increased dynamics.

BACKGROUND: Individuals with severe obesity commonly report poor body image. Improvement in body image has been found after conservative weight reduction programs as well as after bariatric surgery (gastric bypass, biliopancreatic diversion, or gastric banding). However, no studies investigating body image after laparoscopic sleeve gastrectomy (LSG) are available. METHODS: Of 70 consecutive patients who planned to undergo LSG at a comprehensive obesity center, 62 patients were included in the study and evaluated before surgery. Their mean body mass index (BMI) was 51.3 kg/m(2) and the patients' mean age before surgery was 43.8 years. One-year follow-up data were obtained for 51 patients (82.3 %). Body image was assessed using the body image questionnaire (BIQ-20), and depression was assessed using the Patient Health Questionnaire (PHQ-9). RESULTS: Patients reported poor body image before surgery. One year after LSG, negative evaluations of the body and perceptions of body dynamics and vitality had markedly improved, without reaching healthy levels. No correlations between body image and weight-related parameters (BMI, percentage of excess weight loss) or mood after 1 year were found. CONCLUSIONS: Body image improves after LSG. This improvement might reflect changes to patients' attitudes, beliefs, and thoughts rather than real weight lost. Further studies should investigate the factors that mediate improvement of body image after bariatric surgery.
