    Association between depression and eating behaviors among bariatric surgery candidates in a Turkish sample
    (Springer, 2017) Sevincer, Guzin M.; Konuk, Numan; Ipekcioglu, Derya; Crosby, Ross D.; Cao, Li; Coskun, Halil; Mitchell, James E.
    Purpose The purpose of this study was to explore further whether depression is associated with problematic eating behaviors in a sample of Turkish bariatric surgery candidates. Methods: This descriptive study included 168 consecutively seen bariatric surgery candidates in a university bariatric surgery outpatient. Participants were asked to complete the Dutch Eating Behavior Questionnaire (DEBQ), the Beck Depression Inventory (BDI) and surveys assessing sociodemographic and clinical variables. Correlations and linear regression analyses were performed to evaluate the relationship between clinical and demographic variables. Results: Participants had a mean age 37.7 +/- 11.3 years and BMI of 46.4 +/- 6.7 kg/m(2) (SD = 6.7). According to BDI scores, 75.5 % of the patients had mild, moderate, or severe depressive symptomatology. Lower levels of depressive symptoms were associated with higher levels of restrictive eating (r = -0.17; p = 0.04), whereas higher levels of depressive symptoms were associated with more frequent eating in response to both internal (r = 0.3; p = 0.002) and external (r = 0.2; p = 0.04) cues. The BDI scores were significantly associated with increased external eating (beta= 0.03, p < 0.02) and emotional eating (beta= 0.03, p < 0.002) scores. BMI (beta = -0.02, p = 0.02 > 0.1) was not associated with DEBQ total scores. Conclusion: This research suggests that mild, moderate or severe depressive symptoms are observed in most of the bariatric surgical candidate patients. There is a positive correlation between severity of depression and emotional/external eating behaviors, and a negative correlation between severity of depression and restrictive eating behavior. Additional research is needed to determine whether treating depression preoperatively can assist with alleviating problematic eating behaviors.

    Determinants of Night Eating Syndrome in Bariatric Surgery Candidates
    (Yerkure Tanitim & Yayincilik Hizmetleri A S, 2016) Sevincer, Guzin M.; Bozkurt, Suleyman; Akin, Ercan; Kose, Samet
    Objective: In the present study, it was aimed to examine the clinical correlates of Night Eating Syndrome among bariatric surgery candidates and its relationship with depression, anxiety, and eating disorders. Methods: The study was conducted in a voluntary patient group (n=141) who attend to the Clinic of Bariatric and Metabolic Surgery of Faculty of Medicine of Bezmialem Vakif University between June 2013 and August 2014 to have obesity surgery. The participants were asked to complete the Night Eating Questionaire, the Eating Disorder Examination-Questionnaire (EDE-Q), the Beck Depression Inventory, and the Beck Anxiety Inventory. Eligible 111 patients who have completed all the questionnaires were included for statistical analyses. Results: The results show that 16 participants (14.4%) of the study sample got a score of 30 or over from The Night Eating Questionaire and according to proposed diagnostic criteria, 8.1% (n=9) of the study sample were identified with Night Eating Syndrome. 22.5% of the sample (n=25) had Binge Eating Disorder. Out of these participants, 43 (38.7%) scored 17 and over from Beck Depression Inventory, and 41 (% 36.9) scored 16 and over from the Beck Depression Inventory. While 8.1% (n=9) of sample group met the criteria for both Binge Eating Disorder and Night Eating Syndrome, 65.8% (n=73) met neither Binge Eating Disorder nor Night Eating Syndrome. While 16 patients (14.4%) met the criteria of Binge Eating Disorders but not met ones of Night Eating Syndrome. Moreover, 13 (11.7%) patients who did not meet the criteria for Binge Eating Disorder met the criteria of Night Eating Syndrome. Conclusion: Our results showed that Night Eating Syndrome was in mutual relationship with psychopathologies such as depression and anxiety. This relationship should be consider in the management of the Night Eating Syndrome. Recognition and proper treatment of Night Eating Syndrome is important due to its possible effect on the outcome of obesity surgery. Follow-up studies are needed to examine the effect of Night Eating Syndrome on weight loss in bariatric surgery groups.

    Night Eating Syndrome: Report of a family case
    (Elsevier, 2016) Sevincer, Guzin M.; Allison, Kelly C.
    Night eating syndrome (NES) represents a circadian delay in the pattern of eating. As there are genetic links for other eating- and circadian-based disorders, it is likely that there is a genetic basis for NES as well. We present a family case study of three identified patients and their extensive family history of NES and co-morbid mood disorders. This case report suggested that NES may have a heritable feature, particularly nocturnal ingestions. Of the seven identified cases, four had co-morbid mood disorders, and all descended from a couple with bipolar disorder and delusional disorder. More work is needed to understand the extent of genetic influence on NES, and the relationship between NES and other psychiatric disorders. (C) 2016 Elsevier Ltd. All rights reserved.

    Reliability, validity, and factorial structure of the Turkish version of the Weight Self-Stigma Questionnaire (Turkish WSSQ)
    (Aves, 2017) Sevincer, Guzin M.; Kaya, Aysenur; Bozkurt, Suleyman; Akin, Ercan; Kose, Samet
    OBJECTIVE: The Weight Self-Stigma Questionnaire (WSSQ) is a comprehensive instrument for the assessment of weight self-stigma in obesity and has been validated in several languages. The purpose of this study was to examine the psychometric properties and validate the Turkish version of the WSSQ in a sample of severely obese patients in Turkey. METHODS: A cross-cultural adaptation of the WSSQ into Turkish was carried out, strictly according to recommended methods. The questionnaires including the Sociodemographic data form, the WSSQ, Beck Depression Inventory, Beck Anxiety Inventory, Eating Disorder Examination-Questionnaire, Rosenberg Self-esteem Scale, Dutch Eating Behavior Questionnaire Emotional Eating Subscale, and Impact of Weight on Quality of Life Questionnaire were completed by 120 consecutive severely obese patients (96 female, 24 male) in the outpatient clinics of the Department of Bariatric and Metabolic Surgery in a university setting in Turkey. All statistical analyses were performed by using SPSS version 23 for Windows. RESULTS: The Cronbach's a (internal reliability) for the two subscales of the WSSQ-self-devaluation and fear of enacted stigma, and for the whole questionnaire (WSSQ Total) were 0.74, 0.81, and 0.83, respectively. The self-devaluation subscale, the enacted stigma subscale and the total WSSQ have a good internal consistency. Construct validity also appeared adequate as the WSSQ correlates with other measures largely in the manner we expected. Principal component factor analyses revealed a two-factor structure with an almost identical factor structure to that reported in the original study. Kaiser-Meyer-Olkin Measure of Sampling Adequacy was found to be 0.81 and Barlett's test of Sphericity chi(2) was found as 457.068 (p<.01). CONCLUSIONS: Our results suggested that Turkish WSSQ was a valid and reliable tool with a robust factorial structure to use for measuring weight-related self-stigma in clinical population in Turkey.
