Deaf adolescents' quality of life: a questionnaire in Italian Sign Language.

For some deaf people, sign language is the preferred language, the one in which they feel most comfortable. However, there are very few assessment tools developed or adapted for sign languages. The aim of this study was to translate and adapt in Italian Sign Language (LIS) the Italian version of the Youth Quality of Life Instrument-Deaf and Hard of Hearing Module (YQOL-DHH). The YQOL-DHH is a questionnaire assessing health-related quality of life in young deaf people. The guidelines provided by the authors of the original version were followed. Further controls and changes were made to take into account variability in signers' linguistic skills. This work and availability of the YQOL-DHH questionnaire in LIS, in addition to the Italian version, will ensure accessibility for Italian deaf adolescents.
