Correlation p < 0.001.

Five items on the FACT scale are also included in the HL scale, increasing scale intercorrelations.

The REALM was only administered to English speakers (n = 236), and the SAHLSA was only administered to Spanish speakers (n = 239).

Hospital = Need help reading hospital materials; Forms = Confident in filling out medical forms; Info= Difficulty in understanding written medical information
