These include decision making, socia l and cultural contexts, perceptions and preferences, and environmental bar riers. We review factors known to increase adherence in dietary interventio ns, including education, motivation, behavioral skills, new and modified fo ods, and supportive interactions. We conclude with directions for future st udy, such as improved measurement of diet-related behavior and longitudinal , culturally sensitive interventions.
