摘要：OBJECTIVE:To develop and validate a short health literacy assessment toolfor Portuguese-speaking adults.METHODS:The Short Assessment of Health Literacy for Portuguese-speaking Adults is an assessment tool which consists of 50 items that assessan individual’s ability to correctly pronounce and understand common medicalterms. We evaluated the instrument’s psychometric properties in a conveniencesample of 226 Brazilian older adults. Construct validity was assessed bycorrelating the tool scores with years of schooling, self-reported literacy, andglobal cognitive functioning. Discrimination validity was assessed by testingthe tool’s accuracy in detecting inadequate health literacy, defined as failureto fully understand standard medical prescriptions.RESULTS:Moderate to high correlations were found in the assessment ofconstruct validity (Spearman’s coefficients ranging from 0.63 to 0.76). Theinstrument showed adequate internal consistency (Cronbach’s alpha=0.93)and adequate test-retest reliability (intraclass correlation coefficient=0.95).The area under the receiver operating characteristic curve for detection ofinadequate health literacy was 0.82. A version consisting of 18 items wastested and showed similar psychometric properties.CONCLUSIONS:The instrument developed showed good validity andreliability in a sample of Brazilian older adults. It can be used in research andclinical settings for screening inadequate health literacy.
