Personality Profiles of the Morbidly Obese after Vertical Banded Gastroplasty
Obesity Surgery, 2003
Background: The authors attempted to determine if mental status could predict personality profiles, 18 months after surgery in morbidly obese patients. Methods: Personality characteristics of 100 morbidly obese patients (85 female, 15 male) were analyzed after bariatric surgery (vertical banded gastroplasty). Patients were given the Millon Clinical Multiaxial Inventory-II (MCMI-II). Data were compared with a Spanish clinical population to validate the test in our country. Results: Significant differences were found in Schizoid scale (P<0.0001), Paranoid scale (P<0.001), Histrionic scale (P<0.0001), Compulsive scale (P<0.0001), and Delusional disorder scale (P<0.0001) between the two groups. When psychiatric comorbidity appeared, there were higher values on these scales. Conclusions: Morbidly obese patients undergoing bariatric surgery show traits and personality disturbances, and the mental state impairs the personality structure.

Objective: Bariatric surgery is an effective treatment for obesity, which has been increasing worldwide. However, bariatric surgery causes dramatic physical changes that can cause significant stress. Prior research has found that psychological variables such as personality traits and levels of psychopathology can influence success after bariatric surgery (in terms of body-mass index [BMI] reduction and weight loss). However, most prior studies have been limited by small sample sizes, inconsistent follow-up, and categorical assessment of psychopathology. Methods: The present study examines the predictive utility of the Personality Assessment Inventory (PAI) scales for three bariatric surgery outcomes (BMI reduction, weight loss, and percent excess weight loss [%EWL]) across ten follow-up points five years after surgery. It also examines the largest sample of bariatric surgery-completing patients (N = 2,267) on the PAI to date. Latent growth modeling was used to examine change in the ...
Psychopathology in a sample of candidate patients for bariatric surgery
International Journal of Psychiatry in Clinical Practice, 2013
Background. The prevalence of morbid obesity and the popularity of bariatric surgery have grown in recent years. Many surgical protocols require that the candidates undergo a pre-operative psychological evaluation. We describe the psychopathological characteristics of both clinical syndromes (Axis I of the DSM-IV), as well as personality disorders (Axis II of the DSM-IV), in a sample of morbidly obese patients accepted as bariatric surgery candidates and who participate in a specifi c surgery preparatory programme, and we analyze its relationship with personality clusters. Methods. The Millon Clinical Multiaxial Inventory-III (MCMI-III) scores from 50 patients attending for bariatric surgery were cluster analyzed in hopes of identifying clinical subgroups corresponding to typical personality profi les. Results. With regard to personality disorders, the highest prevalence was found in the histrionic disorder, followed by obsessivecompulsive disorder. Cluster analysis revealed three personality profi les, which were validated by examining demographics, morphological variables, scores on anxiety and depression psychometric scales, and MCMI-III clinical scales scores. Groups were different in virtually all the MCMI-III clinical scores, as well as in depression and trait anxiety, with Cluster 3 presenting the worst scores. Conclusions. These fi ndings suggest that morbidly obese patients are heterogeneous in their psychological profi les, highlighting Cluster C disorders.
Personality characteristics and bariatric surgery outcomes: a systematic review
Trends in psychiatry and psychotherapy
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. 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. 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. 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 p...
Personality and Obese Body Mass Index
PsycEXTRA Dataset, 2000
This study investigated the relationship between obese range Body Mass Index (BMI) and personality variables as measured by the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). The sample consisted of 129 obese participants referred for preoperative psychological evaluation. Each completed an MMPI-2 and clinical interview. Multilevel linear regression analysis was used to assess the contribution of personality variables to the prediction of variance in obese range BMI. Age, Scale 9 (Hypomania), and Scale 4 (Psychopathic Deviate) emerged as statistically significant predictors of BMI. Each predicted 7.8%, 6.4%, and 3.1% of the variance of participant BMI, respectively, with a combined prediction power of 17.3%. F-scores for the final, best fit model, with age on Level 1 and Scale 9 and Scale 4 on Level 2, were statistically significant (p<.0009). Results suggest severely obese bariatric surgery candidates may be more prone to impulsivity, irritability, and instability. However, limited predictive power of MMPI-2 scales indicates restricted clinical utility.

Background: Obesity is a chronic disease that causes several medical and psychiatric complications. There are plenty of pharmacological and non-pharmacological therapies for obesity treatment. Bariatric surgery is one of the most efficient nonpharmacological treatment for morbid obesity; however, several psychological factors affect the success of bariatric surgery. This study aims to evaluate personality characteristics and eating attitude relationship with the success of bariatric surgery. Methods: This study was carried out on 75 patients with obesity who were candidates of bariatric surgery in the obesity clinic of Rasoul-e-Akram Hospital in Tehran. The patients were asked to fill the TCI and EAT-26 questionnaires before and after the surgery. Statistical analyses were performed using the SPSS-23 applying T-test, Mann-Whitney tests and Pearson and Spearman's correlation coefficient. The significance level was set at 0.05. Results: Seventy-five patients, including 13 men and ...
Personality Features in Obesity
Frontiers in Psychology, 2021
Obesity is a widespread and broadly consequential health condition associated with numerous medical complications that could increase mortality rates. As personality concerned individual’s patterns of feeling, behavior, and thinking, it may help in understanding how people with obesity differ from people with normal-weight status in their typical weight-relevant behavior. So far, studies about personality and BMI associations have mainly focused on broad personality traits. The main purpose of this study was to explore the personality and health associations among a clinical group composed of 46 outpatients with overweight/obesity (mean age = 55.83; SD = 12.84) in comparison to a healthy control group that included 46 subjects (mean age = 54.96; SD = 12.60). Both the clinical and control groups were composed of 14 males and 32 females. Several personality and psychopathological aspects were assessed with the Personality Assessment Inventory (PAI). The results of the analysis of vari...

Background: Personality pathology does not have to be a contraindication to a bariatric surgery if a proper pre-surgical assessment is done. Indicating subgroups of patients with their specific needs could help tailor interventions and improve surgical treatment outcomes. Objectives: Using the Alternative DSM-5 model for personality disorders (AMPD) and the ICD-11 model for PDs to detect subgroups of patients with obesity based on a specific constellation of maladaptive personality traits and the level of overall personality impairment. Methods: 272 consecutively consented patients who underwent a standard presurgical psychological assessment. The majority were women (58.0%), age range was 22-79 years (M = 48.06, SD = 10.70). Patients' average body mass index (BMI) was 43.95 kg/m 2. All participants were administered the Personality Inventory for DSM-5 (PID-5) from which Level of Personality Functioning Scale-Self Report (LPFS-SR) and Standardized Assessment of Severity of Personality Disorder (SASPD) scores were gained using the "crosswalk" for common metric for self-reported severity of personality disorder. The k-means clustering method was used to define specific subgroups of patients with obesity and replicated for equality testing to the samples of non-clinical respondents and psychiatric patients. Results: The cluster analysis detected specific groups in the sample of patients with obesity, which differed quantitatively from the samples of non-clinical respondents and psychiatric patients. A vast majority of patients with obesity showed above-average values in most of the PID-5 facets compared to the United States representative general community sample. In two out of the three clusters defined, patients demonstrated moderate (> M + 1.5 × SD) to severe (> M + 2.0 × SD) personality psychopathology within the Detachment and Negative Affectivity domains according to PID-5, which in one of the clusters corresponded to the mild overall impairment in both, LPFS-SR (M = 2.18, SD = 0.27) and SASPD (M = 8.44, SD = 2.38). Moreover, higher levels of psychopathology prove to be associated with higher age and use of psychiatric medication.
