Does an implementation intention-based stress management support tool reduce stress-induced unhealthy snacking?
An implementation intention-based stress management tool effectively protects against stress-induced high-calorie snack consumption.
Supports SMS tool for stress-related snacking; extends behavioral interventions to dietary choices under stress.
BACKGROUND: Stress may indirectly contribute to disease (e.g. cardiovascular disease, cancer) by producing deleterious changes to diet. PURPOSE: The purpose of this study was to test the effectiveness of a stress management support (SMS) tool to reduce stress-related unhealthy snacking and to promote stress-related healthy snacking. METHODS: Participants were randomized to complete a SMS tool with instruction to link stressful situations with healthy snack alternatives (experimental) or a SMS tool without a linking instruction (control). On-line daily reports of stressors and snacking were completed for 7 days. RESULTS: Daily stressors were associated with unhealthy snack consumption in the control condition but not in the experimental condition. Participants highly motivated towards healthy eating consumed a greater number of healthy snacks in the experimental condition on stressful days compared to participants in the experimental condition with low and mean levels of motivation. CONCLUSIONS: This tool is an effective, theory driven, intervention that helps to protect against stress-induced high-calorie snack consumption.

O’Connor et al. (2014) conducted an RCT in Stress-induced eating. Stress management support (SMS) tool with linking instruction vs. SMS tool without linking instruction was evaluated on Daily unhealthy and healthy snack consumption. An implementation intention-based stress management support tool prevented the association between daily stressors and unhealthy snack consumption compared to a control tool.
