Abstract

Background: Obesity can be a significant challenge to health and quality of life (QoL). Bariatric surgery assists with weight loss and may help improve QoL. However, not all patients benefit from surgery. Personality traits may be related to QoL outcomes after bariatric surgery, but these associations are unclear. Purpose: This research reviews the published literature on the associations between personality and QoL among post‐operative bariatric patients. Method: Four databases (CINAHL Complete, Medline with Full Text, APA PsycINFO, and Scopus) were searched from inception until March 2022. Forward searching was conducted using Google Scholar, and backward reference citation searches were also performed. Results: Five studies met inclusion criteria yielding data from N = 441 post-bariatric patients including both pre/post and cross-sectional designs. Higher agreeableness was related to lower overall health-related QoL (HRQol) and gastric HRQol and positively associated with psychological HRQol. Higher emotional stability was positively related to overall HRQol. Higher impulsivity was negatively associated with mental HRQol and was unrelated to physical HRQol. Effects for the remaining traits were either mainly mixed or null. Conclusion: Personality traits may be associated with HRQol outcomes. However, it is difficult to reliably discern the role of personality traits for HRQol and QoL outcomes given the methodological issues and few published studies. More rigorous research is needed to address these issues and clarify possible associations.
