Outcome Measures

Primary Outcomes (6)

  • Change in Binge-Eating Frequency

    Binge-eating frequency is a continuous variable of binge-eating episodes assessed using interview (Eating Disorder Examination interview). The Eating Disorder Examination uses a 28 day recall of eating behavior. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM -5) defines binge-eating as "eating, in a discrete period of time an amount of food that is definitely larger than most people would eat during a similar period of time and under similar circumstances and a sense of loss of control over eating during the episode." The number of episodes that meet this description will be counted and totaled.

    From baseline interview at study enrollment to 3 months after the 12-week treatment.
