Effects of changes in life circumstances on interaction and communication in adults with congenital deafblindness and an intellectual disability

This study examined the effects of the first 2 years of the ongoing Project CHANGE, aimed at improving interaction and communication in adults with congenital deafblindness (CDB) and an intellectual disability (ID). Six adults with no history of deafblind education participated in this study. These first 2 years of CHANGE involved an improvement in living conditions, including a transition to a new group home and interactions with specialized caregivers. Video recordings and file information were used to measure interaction and communication during baseline (T0) and two subsequent periods (T1 and T2). The results show an improvement in interaction: attention by the caregiver, confirmation by the caregiver, and affective involvement all improved. An improvement was also shown in the participants’ level of expressive communication and in the variety of their communicative behaviors. The improvements over time emphasize the need for a specific approach for persons with CDB and an ID.
