Assessing Intentions to Eat Low-Glycemic Index Foods by Adults with Diabetes Using a New Questionnaire Based on the Theory of Planned Behaviour

摘要

Objective: The Canadian Diabetes Association recommends that people with diabetes choose foods with low-glycemic index (GI). This study developed a questionnaire measuring Theory of Planned Behaviour (TPB) constructs relative to consuming a low-GI diet by people with diabetes so as to achieve a better understanding of which TPB constructs, demographic characteristics and diabetes-related variables best predict intention to consume a low-GI diet.
