Video script was divided in three blocks with their respective items: Block A – AIDS, transmission forms, signs and symptoms, diagnosis, treatment, prevention; Block B – Kinds of protection.

Among deaf people, average CVI of 0.87 was obtained. Total Cronbach's Alpha for the judges was 0.989 and, for the deaf subjects, 0.634.
