Inhibitory control, the ability to inhibit one’s automatic responses to desirable stimuli, may be inadequately targeted in interventions for loss-of-control eating. Promising evidence has identified inhibitory control trainings (ICTs) as an avenue to target inhibitory control directly; however, effects of ICTs on real-world behavior are limited. Compared to typical computerized trainings, virtual reality presents several potential advantages that may address key shortcomings of traditional ICTs, i.e. poor approximation to everyday life. The present study utilized a 2x2 factorial design of treatment type (ICT vs sham) by treatment modality (VR vs standard computer) to examine 1) the feasibility and acceptability of six weeks of daily training; 2) the main and interactive effects of treatment type and modality on target engagement and efficacy (i.e., training compliance, change in LOC eating episodes, inhibitory control, and implicit liking of foods). Participants (N = 35) with ≥ 1x/weekly LOC eating were assigned to one of four conditions and completed ICTs daily for six weeks. The treatment was feasible and acceptable, which was supported by high retention and compliance across time and condition. Although completing daily trainings across treatment types and modalities was associated with large decreases in LOC, there were no significant effects of either treatment type or modality, nor a significant interaction effect, on LOC or mechanistic variables. The mechanism driving overall improvements in LOC may be increased goal salience; future research should test whether goal salience interventions may be an effective and highly disseminable treatment option for LOC eating. |
