Abstract
BACKGROUND Symptomatic postbariatric hypoglycemia (PBH) is a known complication that can occur a few years after Roux-en-Y gastric bypass (RYGB). There is currently no established rating scale for PBH-associated symptoms developed for use in Swedish populations. The aim of the study was to translate an already existing questionnaire into Swedish and to test its reliability. METHODS The study included forward and backward translations of the original Dumping Severity Scale (DSS) questionnaire with 8 items regarding symptoms of early dumping and 6 items regarding hypoglycemia, with each item graded on a 4-point Likert scale. The reliability of the Swedish translated questionnaire (DSS-Swe) was estimated using internal consistency and test-retest methods. RESULTS A total of 200 patients were included in the study. Good internal consistency was demonstrated regarding the items related to early dumping symptoms, with a Cronbach's alpha coefficient of 0.82, and very good agreement in terms of test-retest reliability, with an overall intraclass correlation coefficient (ICC) of 0.91 (95% CI 0.88-0.93). The items related to hypoglycemia yielded a good Cronbach's alpha coefficient of 0.76 and an ICC of 0.89 (95% CI 0.85-0.91). CONCLUSION The DSS-Swe questionnaire shows good reliability regarding both internal consistency and test-retest performance for use in Swedish populations.

VALIDITY OF THE BRAZILIAN-PORTUGUESE VERSION OF MOOREHEAD-ARDELT QUALITY OF LIFE QUESTIONNAIRE II AMONG PATIENTS WITH SEVERE OBESITY.

Abstract
BACKGROUND Patients with obesity present multiple comorbid psychiatric conditions and experience impairments in health-related quality of life. Reliable and valid tools that evaluate health-related quality of life are essential for clinical practice. AIMS This study aimed to investigate the reliability and validity of the six-item Moorehead-Ardelt Quality of Life Questionnaire II among Brazilian patients with severe obesity. METHODS We assessed 387 patients (mean age 43 years, 78.8% women, mean body mass index of 46.5 kg/m²) on the waiting list of a bariatric surgery center. Trained research assistants concurrently applied the Moorehead-Ardelt Quality of Life-II, the Montgomery-Åsberg Depression Rating Scale, and the Global Assessment of Functioning for assessing health-related quality of life, comorbid depressive symptoms, and patient functioning level, respectively. RESULTS The internal consistency of the Moorehead-Ardelt Quality of Life-II was considered acceptable. The total score was correlated with the severity of depressive symptoms and functioning level. The more body mass index increases, the more health-related quality of life worsens. The Moorehead-Ardelt Quality of Life-II presented a unidimensional structure. CONCLUSIONS The unidimensional Moorehead-Ardelt Quality of Life-II is a reliable and valid measure for evaluating health-related quality of life in Brazilian patients with severe obesity. The questionnaire allows to quickly assess the health-related quality of life of patients in different bariatric contexts, considering depression and functional level.

Abstract
Background Depression has been shown to have a negative impact on the outcomes of metabolic surgery and quality of life (QOL). Currently, there are limited data on mental distress and QOL in metabolic surgery candidates in South Africa. Aim This study aimed to determine the prevalence of depressive symptoms at the time of presurgical assessment in participants undergoing metabolic surgery. Setting The Obesity and Metabolic Surgery Initiative at Tygerberg Hospital. Methods We conducted pre-operatively a retrospective cross-sectional study on patients who underwent metabolic surgery from September 2017 to September 2019. Participants were profiled in terms of metabolic parameters, depressive symptoms and QOL. Results Of the 157 participants assessed, 88% were female with a body mass index in the super obese range. Twenty-two percent of participants had depressive symptoms. Metabolic surgery candidates with depressive symptoms had a significantly poorer overall QOL score compared with those without depressive symptoms. When controlling for all other variables, an increase in QOL score was shown to decrease the odds of current depressive symptoms, whilst back pain on non-narcotic medication and having had a stroke were found to increase the odds of current depressive symptoms. Conclusion This study highlights the complex interplay between metabolic, clinical and psychiatric factors in patients undergoing metabolic surgery. The study highlights the vital role of a psychiatrist as part of a multidisciplinary team pre- and post-operatively in the early identification of depressive symptoms. Psychiatrists may have an important role to play as part of the multidisciplinary team in metabolic surgery, including screening for mental health problems pre- and post-operatively, providing psychoeducation and relevant pharmacological treatment and psychotherapy where needed. Contribution This study expands our limited knowledge of psychiatric comorbidity (in particular depressive symptoms and associated factors) in people undergoing metabolic surgery in low- and middle-income countries.

Abstract
OBJECTIVE The objective of this study is to systematically assess the quality of existing patient-reported outcome measures developed and/or validated for Quality of Life measurement in bariatric surgery (BS) and body contouring surgery (BCS). METHODS We conducted a systematic literature search in PubMed, EMBASE, PsycINFO, CINAHL, Cochrane Database Systematic Reviews and CENTRAL identifying studies on measurement properties of BS and BCS Quality of Life instruments. For all eligible studies, we evaluated the methodological quality of the studies by using the COnsensus-based Standards for the selection of health Measurement INstruments checklist and the quality of the measurement instruments by applying quality criteria. Four degrees of recommendation were assigned to validated instruments (A-D). RESULTS Out of 4,354 articles, a total of 26 articles describing 24 instruments were included. No instrument met all requirements (category A). Seven instruments have the potential to be recommended depending on further validation studies (category B). Of these seven, the BODY-Q has the strongest evidence for content validity in BS and BCS. Two instruments had poor quality in at least one required quality criterion (category C). Fifteen instruments were minimally validated (category D). CONCLUSION The BODY-Q, developed for BS and BCS, possessed the strongest evidence for quality of measurement properties and has the potential to be recommended in future clinical trials.

Eat Weight Disord 2016; 21:277-88. [PMID: 26429794 DOI: 10.1007/s40519-015-0222-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2015] [Accepted: 09/05/2015] [Indexed: 11/25/2022] Open
Abstract
PURPOSE Several health-related quality-of-life (HRQoL) dimensions are affected by obesity. Our goal was to characterize the psychometric properties of the ORWELL-R, a new obesity-related quality-of-life instrument for assessing the "individual experience of overweightness". METHODS This psychometric assessment included two different samples: one multicenter clinical sample, used for assessing internal consistency, construct validity and temporal reliability; and a community sample (collected through a cross-sectional mailing survey design), used for additional construct validity assessment and model fit confirmation. RESULTS Overall, 946 persons participated (188 from the clinical sample; 758 from community sample). An alpha coefficient of 0.925 (clinical sample) and 0.934 (community sample) was found. Three subscales were identified (53.2 % of variance): Body environment experience (alpha = 0.875), Illness perception and distress (alpha = 0.864), Physical symptoms (alpha = 0.674). Adequate test-retest reliability has been confirmed (ICC: 0.78 for the overall score). ORWELL-R scores were worse in the clinical sample. Worst HRQoL, as measured by higher ORWELL-R scores, was associated with BMI increases. ORWELL-R scores were associated with IWQOL-Lite and lower scores in happiness. CONCLUSIONS ORWELL-R shows good internal consistency and adequate test-retest reliability. Good construct validity was also observed (for convergent and discriminant validity) and confirmed through confirmatory factor analysis (in both clinical and community samples). Presented data sustain ORWELL-R as a reliable and useful instrument to assess obesity-related QoL, in both research and clinical contexts.
