The main purpose of this study was to explore the relationship between online social networking and offline social participation among people with disability. The results show that evaluation of OSN as a facilitator of social involvement is quite high, but is only weakly positively correlated to offline participation mean scores. However, as OSN users, people with motor disabilities tend to evaluate OSN more positively when their offline participation is more restricted, while people with vision disabilities report higher usefulness of OSN when their offline participation restriction levels are less. This suggests that people with vision impairment may lack access to assistive technologies, or those technologies are inconvenient, or OSN web design is not adapted to their needs. An additional study is needed to explore the issues related to this digital divide. The strongest motivations for why people with disabilities join OSN are related more to maintenance of offline connections and less because of seeking entertainment and information splitting. There are positive correlation between offline participation index and motives to expand one‘s social network and to seek out people with similar disabilities. It is mean that people with disabilities who have more offline participation restrictions seek to expand their social relationships and to connect to people with similar disability conditions using OSN. People with disabilities the most frequently use OSN as passive consumers, meaning they read information, visit the profiles of other OSN members, etc., and most rarely (about once a month) engage in productive activities such as sharing information, organizing events or conducting commercial activities. The conclusion can be drawn that in Lithuania people with disabilities have a relatively not very high use of OSN as facilitated opportunities to compensate their offline participation restriction, to expand their social networks and to enhance their social capital. One weakness of the current research is the low number of participants with vision and hearing impairments for comparing more statistically significant differences between all of these disability groups. To address this issue, currently an additional survey on Lithuanian OSN users with the most severe vision and hearing impairments, is currently being carried out. Also, for the sake of comparison, a similar survey needs to be conducted on OSN users without disabilities so that significant differences can be identified between social networking of the OSN visitors for those with and without disabilities.
