Rehabilitation healthcare professionals' competence and confidence in differentially diagnosing deafblindness from autism spectrum disorders: a cross-sectional survey in South Africa.

Deafblindness is often underdiagnosed or misdiagnosed as ASD. This is due to the lack of competence and confidence of rehabilitation healthcare professionals in diagnosing it. The findings therefore highlight the need for training of rehabilitation healthcare professionals. Training on deafblindness could be included as part of the curriculum in the various undergraduate programs. Deafblindness could also form part of the Continuous Professional Development (CPD) training programs at various healthcare facilities. A team approach to the training would be ideal as it would facilitate peer learning and support. More research is required as it would inform evidence-based assessment, and management and support strategies for children who are deafblind and their families.
