A content validity and cognitive interview process to evaluate an Illness Perception Questionnaire for African Americans with type 2 diabetes

摘要

ObjectiveThe Illness Perception Questionnaire (IPQ) is the only available and empirically validated tool used to gain insight into patient illness beliefs. However, the IPQ has reliability and validity problems when used with African Americans (AAs) and needs to be culturally-adapted and validated for use with this group. This study aimed to utilize findings from focus groups to culturally adapt the IPQ for use in AAs with diabetes. Ten cognitive interviews among AAs with type 2 diabetes explored patients’ interpretation and understanding of the adapted IPQ.
