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).
