Development and validation of educational hypermedia for family members and caregivers of people with epidermolysis bullosa.

Objectives: to develop educational hypermedia to support the care of people with epidermolysis bullosa; and validate its content, functionality, usability, and efficiency.
Methods: methodological study, based on five phases: analysis and planning; modeling; implementation; evaluation; and distribution. Hypermedia was evaluated by expert judges, using the content validity index, index of agreement, and exact binomial distribution test, considering p > 0.05 and 0.80 agreement ratio to estimate the statistical reliability of CVI and IOA.
Results: in the validation with the judges, hypermedia presented excellent indices of total content validity (CVIt=0.99) and agreement for functionality, usability, and efficiency (IOA=100%), with p > 0.05 in all evaluated items.
Conclusions: the developed hypermedia was considered adequate, with good screens, descriptions, and animations, presenting itself clearly and objectively to be used by patients with epidermolysis bullosa and their family members/caregivers.
