“…Thus, our results support the findings of the literature that associate bariatric surgery with the rapid improvement of medical comorbidities. 6,[28][29][30] Another important aspect of our data is that the patients here assessed had a peculiar characteristic: with a focus on the continued empowerment of patients.…”

Introduction: Morbid obesity has multiple implications for psychological and physical health. Bariatric surgery has been selected as the treatment of choice for this chronic disease, despite the controversial impact of the surgery on psychosocial health. The objective of this study was to describe candidates for bariatric surgery and analyze changes in weight, psychopathology, personality, and health problems and complaints at 6-and 12-month follow-up assessments. Methods: Thirty obese patients (20 women and 10 men) with a mean age of 39.17±8.81 years were evaluated in different dimensions before surgery and 6 and 12 months after the procedure. Results: Six and 12 months after bariatric surgery, patients reported significant weight loss and a significant reduction in the number of health problems and complaints. The rates of self-reported psychopathology were low before surgery, and there were no statistically significant changes over time. The conscientiousness, extraversion, and agreeableness dimensions increased, but neuroticism and openness remained unchanged. All changes had a medium effect size. Conclusions: Our results suggest that patients experience significant health improvements and some positive personality changes after bariatric surgery. Even though these findings underscore the role of bariatric surgery as a relevant treatment for morbid obesity, more in-depth longitudinal studies are needed to elucidate the evolution of patients after the procedure.

“…However, since the elevations were not above the clinical cut-off for these scales, the clinical significance of this finding is unclear. A recent study using both the MMPI-2 and the Millon Multiphasic Clinical Inventory (MCMI-III) found that the K-scale from the MMPI-2 and the Schizoid, Schizotypal, and Compulsive scales from the MCMI-III predicted weight loss, but differentially at various post-operative time points (Belanger, Wechsler, Nademin, & Virden, III, 2010). Additionally, the sample used in this study was inclusive of patients who had been approved without reservation and patients who had received psychological/psychiatric treatment presurgically or concurrent with the procedure, making it difficult to draw conclusions.…”

“…In a cluster analytic approach to determine psychological profiles in 153 candidates for vertical banded gastroplasty, 3 distinct patterns were found that were comprised of combinations of high to low functioning, but these occurred across 7 domains (personality, coping, eating behavior, locus of control, body attitude, social functioning, and health-related quality of life) (van Hout, van Oudheusden, Krasuska, & van Heck, 2006). Generally, the research in the area of personality profiles has pointed to the heterogeneity of presurgical candidates and an inability to uniformly predict outcomes (Belanger 2010).…”

“…According to the same findings, a compulsive personality profile was also negatively associated with weight reduction. 37 Although the authors did not describe what they considered maladaptive eating behavior to comprise (it is unclear whether they are referring, for example, to non-compliance with nutritional guidance, to psychopathological eating behavior, bulimia, etc.) and the instrument employed to assess it is unpublished, it nevertheless appears that patients who exhibited dysfunctions in the externalizing domain were already exhibiting unhealthy eating behavior at 3 months and were more likely not to attend consultations 12 months after the procedure.…”

Trends Psychiatry Psychother. 2017;39(2):124-134. http://dx.doi.org/10.1590/2237-6089-2016 Abstract Introduction: Numerous studies have focused on psychological assessment of bariatric surgery candidates, aiming to identify which psychological variables, including personality characteristics, are related to successful surgical prognosis. Objective: To analyze, by means of a systematic literature review, longitudinal studies that investigated personality traits and disorders as possible predictors of outcomes in bariatric surgery. Method: PsycInfo, PubMed, and Scopus databases were searched for studies published between 2005 and 2015, using the keywords "bariatric" AND "personality." Quantitative longitudinal studies in English, Portuguese, or Spanish were selected for review if they assessed personality as an outcome predictor of BS in people aged 18 years or older. Results: Sixteen articles were analyzed. The results of this review suggest that externalizing dysfunctions might be associated with less weight reduction, while internalizing dysfunctions appear to be associated with somatic concerns and psychological distress. The persistence dimension (of temperament in Cloninger's model) was positively associated with greater weight loss, while neuroticism (Five Factor Model) and the occurrence of personality disorders were not predictive of weight loss. Furthermore, the results indicate a tendency towards a reduction in personality disorders and neuroticism scores, and an increase in extroversion scores, after BS. Conclusions: Assessment of personality characteristics, whether to identify their predictive power or to detect changes during the BS process, is important since it can provide grounds for estimating surgical prognosis and for development of interventions targeting this population.

Predicting Outcome of Gastric Bypass Surgery Utilizing Personality Scale Elevations, Psychosocial Factors, and Diagnostic Group Membership

Abstract: Results support the K scale of the MMPI-2 as a significant predictor of postsurgical outcome; MCMI scores on the schizoid, schizotypal, and compulsive scales appeared to be better overall predictors of outcome.
