Adapted motivational interviewing for women with binge eating disorder: A randomized controlled trial.

Abstract

In this randomized controlled trial, 108 women with binge-eating disorder (BED) recruited from the community were assigned to either an adapted motivational interviewing (AMI) group (1 individual AMI session + self-help handbook) or control group (handbook only). They were phoned 4, 8, and 16 weeks following the initial session to assess binge eating and associated symptoms (depression, self-esteem, quality of life). Postintervention, the AMI group participants were more confident than those in the control group in their ability to change binge eating. Although both groups reported improved binge eating, mood, self-esteem, and general quality of life 16 weeks following the intervention, the AMI group improved to a greater extent. A greater proportion of women in the AMI group abstained from binge eating (27.8% vs. 11.1%) and no longer met the binge frequency criterion of the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; American Psychiatric Association, 2000) for BED (87.0% vs. 57.4%). AMI may constitute a brief, effective intervention for BED and associated symptoms.

Extending Motivational Interviewing to the Treatment of Major Mental Health Problems: Current Directions and Evidence

“…Dunn et al 57 found few differences between groups on symptom measures, although the MET group showed significantly greater abstinence from binge episodes at 4-month follow-up. Moreover, Cassin et al 20 reported consistent improvements in the MET-enhanced group over self-help alone on various eating disorders and related symptoms of psychopathology. However, a well-controlled randomized study by Treasure et al 58 compared 4 sessions of either MET or CBT in the first phase of treatment for bulimia nervosa and found that while self-reported motivation predicted symptom outcomes, no significant between-group differences were obtained on any outcome measure.…”

“…Interestingly, in addition to behavioural markers of engagement in some studies (for example, treatment attendance), MI-MET has also been quite consistently found to increase self-reported motivation for change among people with eating disorders (for example, see Cassin et al, 20 Feld et al, 55 and Dean et al 56 ). This is quite different from the findings for anxiety, where MI is generally not accompanied by changes in self-reported motivation.…”

“…Within this growing body of literature, the 2 most common uses of MI have been either as a prelude or pretreatment to other therapies, [18][19][20][21] or as an approach that is integrated into standard assessment and intake procedures designed to increase motivation and engagement in treatment. [22][23][24][25] MI has also been commonly added or integrated throughout treatment as one part of a larger multi-component treatment package.…”

“…52,53 Some support has also been reported from uncontrolled 54,55 and nonrandomized 56 studies for group MI as a means of enhancing motivation before more intensive treatment for eating disorders. Two randomized studies have compared brief MET (1 session) plus self-help with self-help alone for BED, 20 and people with subthreshold bulimia and BED. 57 Both studies 20,57 found an increase in self-reported motivation for the MET-enhanced group.…”
