Validation of a Health Literacy Measure for Adolescents and Young Adults Diagnosed with Cancer

Health literacy can influence long-term health outcomes. This study aimed to validate an adapted version of the Functional, Communicative and Critical Health Literacy measure for adolescent and young adult (AYA) cancer patients and survivors (N = 105; age 12-24 years). Exploratory factor analysis was used to validate the measure, and indicated that a slightly modified item structure better fit the results. Furthermore, item response theory analysis highlighted location and discrimination parameter differences among items. Acceptability of the measure was high. This is the first validation of a health literacy measure among AYAs with an illness such as cancer.
