Self-affirmation improves self-control over snacking among participants low in eating self-efficacy

Area of Science:

• Behavioral Psychology
• Health Psychology
• Cognitive Psychology

Background:

• Low eating self-efficacy is linked to unhealthy eating behaviors, particularly high-calorie snacking.
• Individuals with low self-control struggle to avoid tempting snacks.
• Interventions are needed to enhance self-control over snacking in vulnerable populations.

Purpose of the Study:

• To investigate if self-affirmation can increase self-control over snacking.
• To test the hypothesis that self-affirmation benefits individuals low in eating self-efficacy.

Main Methods:

• 70 participants completed baseline measures of dietary restraint and eating self-efficacy.
• A self-affirmation or control task preceded a joystick task assessing self-control over snacking.

Main Results:

• A significant interaction showed self-affirmation moderated the link between eating self-efficacy and self-control.
• Self-affirmation increased self-control for those low in eating self-efficacy.
• Conversely, self-affirmation decreased self-control for those high in eating self-efficacy.

Conclusions:

• The study supports self-affirmation as a method to enhance self-control over snacking in individuals with low eating self-efficacy.
• Self-affirmation may be a valuable tool for managing unhealthy food choices in difficult dietary contexts.
