General Description

IEQ is a self-report measure designed to measure the engagement in inflexible and rigid eating rules (e.g., “I rather follow my eating rules than eating in function of the context or my hunger or will”). IEQ presented an 11-item one-dimensional structure that revealed high internal consistency, construct and discriminant validity, and presented a good temporal stability. Findings suggested that the IEQ is a valid and useful instrument with potential implications for research on psychological inflexibility in disordered eating.
