*3.3. General Psychopathology: BIS-15 & BDI*

BIS-15 total impulsivity scores differed significantly between groups, *F*(2, 128) = 6.48, *p* < 0.002, *η*<sup>2</sup> = 0.09, with OB-BED scoring higher than CO, *p* < 0.001, whereas OB-BED and OB, and OB and CO remained comparable, *p*s > 0.14. Subscale analysis, *F*(6, 252) = 4.56, *p* < 0.001, *η*<sup>2</sup> = 0.10, Wilk's Λ = 0.81, revealed that overall differences were due to OB-BED scoring higher on attentional impulsivity than OB and CO, *p*s < 0.05, and OB scoring higher than CO, *p* = 0.03. All groups remained comparable on non-planning impulsivity and motor impulsivity subscales, *p*s > 0.10.

On the BDI depression inventory, OB-BED scored higher than OB and CO, *p*s < 0.04, and OB scored higher than CO, *p* < 0.001, *F*(2, 126) = 23.78, *p* < 0.001, *η*<sup>2</sup> = 0.27.
