UGARTE, Carla; QUINONES, Álvaro  and  VICENTE, Benjamín. Psychological predictors of the regain of weight in bariatric patients. Ter Psicol [online]. 2019, vol.37, n.3, pp.199-209. ISSN 0718-4808.

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.


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.


Predictive multivariate study. A total of 97 bariatric patients were evaluated.


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.


The variables locus of weight control, positive past and fatalistic present predict the regain of weight.

Keywords : Bariatric Surgery; Locus of Control; Self-efficacy; Time Perspective; Predictors of regain.
