This study explores cultural variance in parental health beliefs, knowledge, and information sources related to attention-deficit/hyperactivity disorder (ADHD). Structured interviews were completed by a representative community sample of 1,615 parents, including an ADHD knowledge and perceptions survey, behavioral questionnaires, and inquiries about ADHD detection and treatment. Most parents had heard about ADHD and considered themselves knowledgeable about it but were unaware of relevant school services; those who were aware rated their knowledge levels as low. Compared to their Caucasian counterparts, African American parents reported less ADHD awareness and lower self-rated knowledge. They experienced fewer cues to action, such as receiving ADHD information from teachers or reading media accounts. Furthermore, they made more etiological attributions to sugar intake and expected less benefit from treatment. Study findings suggest a compelling need for more culturally appropriate approaches to educating African American parents about the causes and treatment options for ADHD. (Contains 4 tables.)
