“…Although no deviant personality profile has been implicated for obese individuals (16,24,25), lack of self‐confidence, neuroticism, and depression (13,26,27,28) have been reported in obese populations. We found small deviations in the personality variables neuroticism, social anxiety, egoism, and self‐esteem, which are mainly suggested to be the result of the obese state, because studies have shown that preoperative depression, anxiety, and low self‐esteem virtually disappear after surgical treatment for morbid obesity (28,29,30). Overall, our data suggest that personality does not meaningfully deviate from the norm.…”

LARSEN, JUNILLA K., RINIE GEENEN, CORA MAAS, PIETER DE WIT, TINY VAN ANTWERPEN, NICO BRAND, AND BERT VAN RAMSHORST. Personality as a predictor of weight loss maintenance after surgery for morbid obesity. Obes Res. 2004;12:1828 -1834. Objective: Personality characteristics are assumed to underlie health behaviors and, thus, a variety of health outcomes. Our aim was to examine prospectively whether personality traits predict short-and long-term weight loss after laparoscopic adjustable gastric banding. Research Methods and Procedures:Of patients undergoing laparoscopic adjustable gastric banding, 168 (143 women, 25 men, 18 to 58 years old, mean 37 years, preoperative BMI 45.9 Ϯ 5.6 kg/m 2 ) completed the Dutch Personality Questionnaire on average 1.5 years before the operation. The relationship between preoperative personality and short-and long-term postoperative weight loss was determined using multilevel regression analysis. Results: The average weight loss of patients progressively increased to 10 BMI points until 18 months after surgery and stabilized thereafter. A lower baseline BMI, being a man, and a higher educational level were associated with a lower weight loss. None of the personality variables was associated with weight outcome at short-term follow-up. Six of seven personality variables did not predict long-term weight outcome. Egoism was associated with less weight loss in the long-term postoperative period. The effect sizes of the significant predictions were small. Discussion: None of the personality variables predicted short-term weight outcome, and only one variable showed a small and unexpected association with long-term weight outcome that needs confirmation. This suggests that personality assessment as intake psychological screening is of little use for the prediction of a poor or successful weight outcome after bariatric surgery.

“…Improvements in psychological functioning after surgery have been reported (10). For example, there is evidence of reductions in anxiety, depression, and negative perception of body shape at 6-month postoperative follow-up (11). Psychological factors have been found not to predict weight loss or drop-out from treatment in the 3 years after surgery (12).…”

Gastric Bypass in a Low‐Income, Inner‐City Population: Eating Disturbances and Weight Loss

These findings indicated that eating and psychiatric disturbances did not inhibit weight loss after gastric bypass and should not contraindicate surgery. Prior binge eating, eliminated after surgery, predicted BMI loss and, thus, may have previously been a maintaining factor in the obesity of these patients. The association between health behaviors and outcome suggests possible targets for intervention to improve surgical results. Poorer outcomes among African Americans indicate that these patients should be closely monitored and supported after surgery.

Patient‐reported outcomes in bariatric surgery: a systematic review of standards of reporting

et al. 2013

Bariatric surgery is increasingly being used to treat severe obesity, but little is known about its impact on patient-reported outcomes (PROs). For PRO data to influence practice, well-designed and reported studies are required. A systematic review identified prospective bariatric surgery studies that used validated PRO measures. Risk of bias in randomized controlled trials (RCTs) was assessed, and papers were examined for reporting of (i) who completed PRO measures; (ii) missing PRO data and (iii) clinical interpretation of PRO data. Studies meeting all criteria were classified as robust. Eighty-six studies were identified. Of the eight RCTs, risk of bias was high in one and unclear in seven. Sixty-eight different PRO measures were identified, with the Short Form (SF)-36 questionnaire most commonly used. Forty-one (48%) studies explicitly stated measures were completed by patients, 63 (73%) documented missing PRO data and 50 (58%) interpreted PRO data clinically. Twenty-six (30%) met all criteria. Although many bariatric surgery studies assess PROs, study design and reporting is often poor, limiting data interpretation and synthesis. Well-designed studies that include agreed PRO measures are needed with reporting to include integration with clinical outcomes to inform practice.
