ProTGTlsm: Design and evaluation of an application for the sexual education of young Mexican deaf people

Abstract

Deaf people who use sign language (SL) are one of the populations most at risk of sexually transmitted infections (STIs) and unwanted pregnancy owing to limited access to reliable information sources in their language. The purpose of this study was to design and evaluate the usability of a web application as an educational strategy to promote sexual health among young Mexican deaf people. A multidisciplinary group of six professionals and seven members of the deaf community participated in the (user-centred) design and construction of the application, called ProTGTlsm. The application consists of five modules: STIs, contraceptive methods, condom use, correct use and condom placement. The usability of the final version of ProTGTlsm was evaluated by 13 young deaf people (7 men and 6 women, aged between 18 and 29 years), according to the criteria established by the ISO 9241-11 standard. The results showed that ProTGTlsm was easy to use, informative and appealing to participants, indicating its utility as part of future measures and actions aimed at this sector of the population.
