OBJECTIVES: Health literacy has been related to indicators of health outcomes in a number of populations, but not in spinal cord injury (SCI). The current study aimed to describe levels of health literacy in SCI and to investigate its possible associations with morbidity, health-related quality of life, functional independence, community participation, and life satisfaction.
DESIGN: Cross-sectional survey of 107 community-living people with SCI recruited in a New Jersey outpatient SCI center. Primary measures were the Test of Functional Health Literacy in Adults (TOFHLA), standard questions about morbidity from the Behavioral Risk Factors Surveillance Study, the Craig Handicap Assessment and Reporting Technique (CHART), Short Form-12 (SF-12), and Diener's Satisfaction with Life Scale.
RESULTS: Health literacy was marginal or inadequate (TOFHLA = 0-74) in only 14% of the sample. TOFHLA scores correlated significantly with physical health morbidity, even after control for severity of motor paralysis and education. American Spinal Injury Association (ASIA) Motor Scores were correlated with physical morbidity and CHART Physical Independence scores; and education was related to community Mobility, Occupation, and Economic Independence, and Satisfaction with Life scores, independent of other factors. Rasch analysis identified ceiling measurement limitations in the TOFHLA.
CONCLUSIONS: Health literacy levels in this sample were higher than those found in other groups. Health literacy was independently related to physical health morbidity, but its associations with other outcomes were limited, entwined with education, and affected by severity of injury. Future research might examine higher-level aspects of health literacy to overcome ceiling measurement problems. Mediators of the association between health literacy and morbidity, such as health self-care behaviors, should also be examined.
