Introduction: The Common Sense Model (CSM) posits that Illness Representations (IRs) are a patient's beliefs and expectations about an illness and that IRs guide health behavior (Leventhal, Brissette, & Leventhal, 2003). This study aimed to examine possible links between youth asthma IRs and disease-related outcomes ( controller medication adherence, asthma control, and lung function) in a sample of black and Latino youth with asthma.
