The aim of this study is to explore the role of attachment styles in obesity.

The present study explored differences in insecure attachment styles between an obese sample waiting for bariatric surgery (n = 195) and an age, sex and height matched normal weight control group (n = 195). It then explored the role of attachment styles in predicting change in BMI 1 year post bariatric surgery (n = 143).

The bariatric group reported significantly higher levels of anxious attachment and lower levels of avoidant attachment than the control non-obese group. Baseline attachment styles did not, however, predict change in BMI post surgery.

Attachment style is different in those that are already obese from those who are not. Attachment was not related to weight loss post surgery.
