*3.4. Early Life Experiences: CTQ & RSQ*

CTQ total scores for childhood trauma revealed significant groups differences, *F*(2, 128) = 19.67, *p* < 0.001, *η*<sup>2</sup> = 0.24, with CO scoring lower than both OB-BED and OB, *p*s < 0.001, and similar scores for OB-BED and OB, *p* = 0.30. In terms of trauma subcategories, group differences were also significant, *F*(10, 248) = 4.51, *p* < 0.001, *η*<sup>2</sup> = 0.15, Wilk's Λ = 0.72, with CO scoring lower than OB-BED and OB in all categories, *p*s < 0.03, except for OB-BED in terms of sexual abuse, *p* = 0.06. OB-BED and OB did not significantly differ in any of the subcategories, *p*s > 0.05. Denial scores indicating underreporting did not differ between groups, *F*(2, 128) = 2.70, *p* = 0.07.

Attachment styles according to RSQ scores differed between groups, *F*(8, 244) = 6.32, *p* < 0.001, *η*<sup>2</sup> = 0.17, Wilk's Λ = 0.69, with differences found on separation anxiety, closeness anxiety, and lack of trust subscales. For separation anxiety, OB-BED revealed elevated scores compared to OB and CO groups, *p*s < 0.03, which themselves remained comparable, *p* = 1.00. Closeness anxiety was only elevated for OB-BED when compared to CO, *p* < 0.001, whereas all other comparisons were not significant, *p*s > 0.15. Finally, all groups differed in lack of trust, *p*s < 0.05, with OB-BED scoring higher than OB and CO, and OB scoring higher than CO. There were no significant differences on the wish to be independent subscale, *p*s > 0.25.
