Emotion regulation and mental well-being before and six months after bariatric surgery

Purpose According to the current state of research, mental health improves due to bariatric surgery. However, improvements in weight and psychosocial aspects often show a gradual decline with time. As emotion regulation (ER) appears to be a key variable in the successful outcome of weight loss treatments, the present study aimed at investigating ER-strategies applied by bariatric surgery candidates pre- and post-surgery and examining interactions between ER, depressive symptoms, health-related quality of life (HrQoL), and post-surgical weight loss. Methods Prior to and 6 months after bariatric surgery, 45 patients (76% women) completed self-report questionnaires assessing depressive symptoms (Beck Depression Inventory-II), HrQoL (Short Form-36 Health Survey), and ER-strategies (Emotion Regulation Inventory for Negative Emotions). Results Six months post-surgery, the patients reported significant improvements in depressive symptomatology, HrQoL, and satisfaction with ER compared to pre-surgery. Groups differing in their course of ER-satisfaction also differed in psychosocial dimensions pre- to post-surgery, increased satisfaction being related to less impairment and enhanced communication of negative emotions as a form of an adaptive regulation. Patients with higher weight loss applied the strategy of controlled expression more frequently post-surgery than pre-surgery and compared to patients with lower weight loss. Conclusions Postoperative weight loss leads to improvements in ER-satisfaction and mental well-being. As satisfaction with ER seems to be associated with less impaired mental well-being among bariatric surgery candidates, presumably even more positive psychosocial outcomes could be obtained post-surgery by implementing trainings explicitly encouraging the use of adaptive ER-strategies.
