About the Validation of this Measure
Country where validated:
Brazil
Content validity:
SAHLPA is based on the REALM, a test popularly used to assess health literacy, but centred on reading skills. SAHLPA is seen as a new instrument because it includes comprehension of written health materials and thus has better content validity than the REALM.
Reliability (Cronbach Alpha):
0.73
Reliability notes:
"Adequeate reliability" -- The lower internal consistency (Cronbach’s alpha = 0.73), when compared to that of the Brazilian SAHLPA-18 version (Cronbach’s alpha = 0.90), could be explained by the lower variability in score distributions, that is known to underestimate the reliability.
