Psychotherapy, which includes multiple forms of treatment such as cognitive behavioral therapy and dialectical behavioral therapy, has been found to cause significant reductions in binge-eating episodes, depression, eating disorder psychopathology, and BMI 12 months after treatment. Final abstinence rates were found to range from 46 to 52%, with a total weight loss of 1.9 to 6.1kg. However, it is important to note that BMI reduction was non-significant at both 3 and 6 months following treatment, but eventually became significant by the 12-month mark.
