El objetivo de la presente investigación fue identificar los rasgos de personalidad característicos de pacientes del Hospital Militar Central de Bogotá, Colombia, candidatos a cirugía Bariátrica. Para ello se revisaron las historias clínicas de 430 pacientes que asistieron a valoración psicológica como candidatos a cirugía Bariátrica, se aplicó inventario MMPI2 y se desarrolló una entrevista semi-estructurada diseñada con base en el formato de evaluación para pacientes con diagnóstico de obesidad mórbida. Se encontró que los rasgos predominantes son las combinaciones 1-2 Hipocondriasis-Depresión para los participantes que presentaban obesidad tipo I y II, y 1-8 Hipocondriasis-Esquizofrenia para los participantes que presentaban súper obesidad. Se concluye una relación entre los perfiles y los comportamientos que caracterizan a las personas obesas, pero no se evidencian dificultades en el desempeño social, tal y como lo corrobora la literatura sobre el tema a nivel mundial.

The Iowa Gambling Task (IGT) is the major plank of behavioral support for the Somatic Marker Hypothesis-a prominent theory of emotionally-based decision making. Despite its widespread use, some have questioned the ecological and discriminative validity of the IGT because a substantial proportion of neurologically-normal adults display a response pattern indistinguishable from those with ventromedial prefrontal cortical brain lesions. In a large sample of healthy adults, we examined the statistical influence of several demographic variables on two versions of the IGT, with the specific prediction that educational attainment would moderate learning across trials. Results confirmed a highly significant effect of education. On the commonly used original version of the IGT, performance tended to improve more rapidly, and reach a higher eventual positive score, as the level of education increased. Age and gender were nonsignificant effects in the model, and Caucasians had slightly better IGT performance than their non-Caucasian counterparts. Conclusions are that education level, among neurologically-normal adults, should be treated as a stratification or matching variable in case

Objective: Patients presenting for bariatric surgery have high rates of psychiatric co-morbidity and reduced health-related quality of life (HRQOL) compared to the general population. In this study, we aimed to determine the relationship between insecure attachment styles and HRQOL in bariatric surgery candidates. Methods: We assessed depression, social support, attachment avoidance, attachment anxiety, HRQOL (SF-36), and eating disorder psychopathology in 70 consecutive patients assessed for bariatric surgery. SF-36 physical (PCS) and mental component scores (MCS) were compared to a normative sample and analyzed using t-tests. Predictors of HRQOL were analyzed using multiple linear regression analyses. Results: SF-36 PCS and MCS in this pre-bariatric surgery sample were significantly lower than in an age-matched reference population. Depression, attachment anxiety, attachment avoidance and eating disorder psychopathology scores were negatively correlated with SF-36 MCS. Depression was associated with lower SF-36 PCS (p = 0.015). SF-36 MCS were significantly predicted by BDI scores (p < 0.001) and attachment avoidance (p = 0.024) in our multiple regression model. Conclusion: This is the first study to demonstrate an association between attachment avoidance and poor mental HRQOL in bariatric surgery candidates. Future studies are needed to examine the effect of attachment avoidance on post-bariatric surgery outcomes.
