Communication and language barriers isolate hearing impaired individuals by depriving them of the opportunities of getting knowledge through different forms of health-related messages and healthcare communication. This put them at higher risk of getting affected by different diseases due to inadequate health literacy (HL). The objective of the study was to assess the existing level of health literacy of adolescent age hearing impaired individuals, along-with to identify the major deficit areas of health literacy. The theoretical framework of the study is based on Nutbeam’s model of health literacy, which divides the HL into three major domains, (i) functional, (ii) interactive, and (iii) critical. It was a cross sectional study, in which data were collected from 299 hearing impaired students (both male and female) studying at Intermediate classes of five public colleges of special education. An adapted instrument of health literacy was used for the data collection purpose, adapted from HELMA (health literacy measure for adolescents). Moreover, to address the unique needs of hearing impaired individuals many statements were included in the instrument through an extensive review of related literature. The final instrument was bilingual (English and Urdu) and named as Health Literacy Assessment Tool for Hearing Impaired (HLAT-HI). The instrument contained major three sections having sub-sections as per the levels of health literacy. Data was collected by face to face component and through correspondence. During data collection, necessary guidelines were provided to respondents in written form and sign language. The results of the study highlighted the major deficit areas of health literacy of hearing impaired students. Their health literacy has been identified as low including major deficit areas of reading, writing, knowledge, understanding, communication, management, and decision making skills. To promote their health literacy it is recommended to use school based health literacy intervention. Moreover, community based health literacy programs for out of school hearing impaired individuals can also be started, to empower them with the latest health related knowlege and skills. It is also recommended to provide training to teachers of special needs children along-with the healthcare professionals.
