Person identity, also in the aspect of experiencing the self as a deaf person, plays an important role in the mental health of deaf and hard-of-hearing people. It has been demonstrated that the deaf identity is related to depression, self-esteem, and well-being. So far, there are no studies of the relation between the person identity, defined in the categories of features/attributes, also these related to the dimension of hearing vs. deaf, which people assign to themselves in comparison to others, and the acceptance of self as a deaf person. This question is the aim of the present study. The study involved 270 people with prelingual deafness who underwent cochlear implantation in their childhood, adolescence or adulthood with high competencies in the Polish phonic language. They received by post the information form and questionnaires. The feedback rate was 32.2%, which is 87 people aged between 18 and 45. In this group, 69 people use one cochlear implant, people in the remaining part of the group use 2 implants. The respondents filled out an information form containing questions about sociodemographic variables as well as data on deafness and cochlear implants. To describe person identity, the I-Others questionnaire was used (modified Questionnaire of Attributes/ Kwestionariusz Cech by M. Jarymowicz). The self-acceptance was measured using the VAS-type scale, on which the tested person marks how much they accept themselves as deaf persons. The results obtained are in the course of statistical analysis, to which t-test, ANOVA, correlations, linear regression were used.
