Effectiveness of cognitive behavioural therapy

 Effect of the Intervention

The patients in the CBT-group had significant improvements in DE, anxiety, and depression compared with the control group patients. A significant reduction in BMI was also observed.

The intervention effects are presented in Figures ​Figures22 and ​and33 showing postinterventional scores for eating behaviors and affective symptoms by treatment. The between-group effect sizes for the improvements varied from high (uncontrolled eating (g = − .90, P ≤ .001), cognitive restraint (g = .92, P ≤ .001)) to moderate (emotional eating (g = − .67, P ≤ .001), anxiety (g = − .62, P ≤ .001), depression (g = − .73, P =  ≤.001)) and low (BMI (g = − .24, P = .004)).Open in a separate windowFigure 2
