Abstract
Background: Treatments for reducing binge eating, a major contributor to obesity, are not sufficiently effective likely because they do not target poor inhibitory control (i.e., an inability to withhold an automatic response), a key driver of binge eating. Computerized inhibitory control training (ICT) is a promising method for improving inhibitory control but is relatively untested for binge eating. Methods: The present study evaluated a computer-based ICT as an adjunct to cognitive behavioral treatment (CBT) for binge eating in a pilot randomized trial. Participants (n=63) with frequent binge eating (> 1x/week) were randomized to CBT + ICT or CBT + a sham training. Trainings were completed daily, on participants home computers, for 4 weeks and weekly for 8 weeks while receiving 12 weeks of CBT. ICTs were personalized such that they trained inhibition specifically to foods participants reported as binge foods and adaptive such that the ICT became more challenging as participants improved their inhibitory control. Results: Individuals who received ICT experienced large and statistically significant improvements in inhibitory control (F=34.29, p<.01), and improvements in inhibitory control were associated with improvements in binge eating (r=.39,p=.03). Although the study was not powered for formal tests of efficacy, analyses suggested that individuals in the ICT experienced meaningfully greater improvements in binge eating compared to those in sham. Those who received sham reported binge eating with more than double the frequency than those in ICT at post-treatment (11.27 vs. 4.93 binge episodes). Furthermore, ICT produced a binge eating remission rate of 41%, compared to 24% in sham at post-treatment. These differences were largely maintained at 3-month follow-up. Conclusions: This initial trial demonstrates the initial promise of a computerized, personalized ICT to augment treatment for binge eating. Future research should examine whether ICTs can improve other types of dysregulated eating and enhance weight loss outcomes.
