Predictores psicológicos de la re-ganancia del peso en pacientes bariátricos

Bariatric surgery allows a significant and accelerated weight loss in the short term. The regain of the weight is observed between 15 to 30% of the patients. The psychological factors would explain to a greater extent the recovery of weight in bariatric patients. Aim: To evaluate the predictive capacity of the variables “locus of weight control”, “temporal perspective” and “self-efficacy”, for the re-gain of weight in bariatric patients. Method: Predictive multivariate study. A total of 97 bariatric patients were evaluated. Results: The psychological variables “locus of control”, “present fatalist” and “positive past” explain 27.1% of the variance of the regain of weight (p <.001). This model correctly classifies 88.7% of patients. Conclusion: The variables locus of weight control, positive past and fatalistic present predict the regain of weight.
