While disability identity has been widely used in various studies of the disabled, there has been few empirical research on whether and how it differed among the disabled. This study aims to explore the factors associated with the measures of disability identity in total and its five components in individual – human value, acceptance of disability, civil rights, common ground, and external barrier. The factors considered in the study include social relations(experience of discrimination, social support), socio-demographic characteristics(sex, age, education etc.) and characteristics of disability(degree, cause, type and length of the disability). The analysis, based on the 2nd wave survey on the disabled persons conducted by SSK research team, revealed that there were common variables affecting five components in a similar way. This was the case with social support. Thus, it was reasonable to view social support as a promoter of disability identity. In the meanwhile, there were found variables with different influences according to the components of disability identity. Education level has affected on disability acceptance of all components of disability identity. For human value and acceptance of disability, effective were disability caused by accident and heavy disability: for civil rights and external barrier, experience of discrimination, physical disability, visible and hearing impairment; for common ground, age. The findings on variation in significant variables across the five components of disability identity suggest that the use of disability identity as a single measure require detailed caution in research plan. In addition, they provide a ground for more strategic approach to enhance disability identity in practice.
