- Description
- This cross-sectional research examines psychosocial, eating and general psychopathology, health-related quality of life, weight and surgery features of prospective bariatric surgery candidates. Participants were two-hundred and twenty-five participants sourced from general and bariatric surgery-related social media websites, and through the use of advertisement posters displayed throughout the University of Newcastle, Australia. Non- and standardised measures were administered to participants through an anonymous online computer-based questionnaire that assessed participants’ psychosocial, eating and general psychopathology, health-related quality of life, weight category, weight loss, and surgical intentions. A Multiple Linear Regression was used to investigate psychosocial predictors of weight. An ANOVA assessed differences in psychopathology between groups, whilst controlling for intention to undergo bariatric surgery and weight category. A demographics analysis explained variance, including features of dropped-out participants. The results confirmed that obese participants intending to undergo bariatric surgery were more likely to suffer from Binge Eating Disorder (BED), other eating, psychosocial and psychopathological problems, including self-harm and harm to others, and trauma problems; with childhood trauma significantly positively correlating with BED in this group. Overweight participants not intending to undergo bariatric surgery were more likely to have poor work life quality. Across all weight categories and surgical intention groups, there was a significant effect of psychosocial and trauma problems, BED, childhood trauma, depression symptoms, and low self-esteem. There was no significant relationship between participants’ depression, anxiety, and stress symptoms, self-esteem and hopelessness features on participants’ weight category and intention to undergo bariatric surgery. The results highlight the significant impact of eating and other psychopathology and psychosocial features on weight category and intention to undergo bariatric surgery, particularly in the context of BED. The results further suggest that obese participants intending to undergo bariatric surgery are vulnerable to psychosocial risk factors, eating, and other psychopathologies. These findings have important implications for introducing pre- and postoperative interventions to target these problematic features to achieve successful weight loss outcomes in bariatric surgery candidates.
