Psychosocial predictors of bariatric surgery success have been evaluated throughout the literature. Patients with pre-existing mental health disorders have been associated with poorer surgical outcomes. The aim of this study was to evaluate pre-existing mental health with SIPAT scores as well as psychotropic medications within this population.


Data were collected from December 2017-March2019, with 165 pre-surgical psychological evaluations for patients considering bariatric surgery. Mean age of the sample was 45.4 (SD = 11.08), and 143 females (86.7%) were interviewed. Mental health history was defined as a prior or current mental health diagnosis and psychotropic medication use was defined as current or prior use via self-report and EMR search.


Descriptive statistics followed by independent sample t-tests were completed using SPSS. 107(64.8%) of the sample had a history of mental health diagnosis and 110(66.7%) had taken psychotropic medications. Both mental health history and use of psychotropic medication use significantly predicted SIPAT scores: t(161)=-4.47, p<.001 and t(161)=-4.53, p<.001, mental health history and medical use predicting poor candidacy scores for bariatric surgery.


Prior research identified mental health history as a predictor of poorer outcomes for patients going through bariatric surgery process. Preliminary analyses examining mental health history and use of psychotorpic medications suggest that it significantly impacts surgical candidacy scores using the SIPAT. The SIPAT's total score may be a good overall indicator of a bariatric surgery patient's candidacy. Future research assessing health outcomes using the SIPAT and mental health history are necessary.
