Australian families of deaf and hard of hearing children: Are they using sign?

BACKGROUND

Deaf and hard of hearing (DHH) children may experience communication delays, irrespective of early intervention and technology. Australian Sign Language (Auslan) is one approach in early intervention to address language delays. Current prevalence of Auslan use among Australian families with DHH children is unknown.

AIMS

The first aim was to determine the proportion of families enrolled in an Australian statewide hearing loss databank who use Auslan with their DHH child. The second aim was to explore the relationships between indicators of child hearing loss (bilateral or unilateral hearing loss, degree of hearing loss, and device use: hearing aids and cochlear implants), family factors (maternal education, attendance at early intervention, family history of deafness, and socio-economic disadvantage) and the family's reported use of Auslan.

METHODS

We analysed the enrolment data from 997 families who participated in an Australian statewide hearing loss databank between 2012 and 2021. We described the proportion of families who used Auslan with their DHH child at home. The association between indicators of child hearing loss and family factors, and the parental reports of communication approach were examined using correlation analyses.

RESULTS

Eighty-seven of 997 parents (8.7%) reported using Auslan with their DHH child. Of these, 26 (2.6%) used Auslan as their primary language. The use of Auslan at home was associated with the following indicators of child hearing loss: bilateral hearing loss, profound compared to mild hearing loss, and cochlear implant and hearing aid use compared to no device use. The family factors associated with the use of Auslan were: referral or attendance at early intervention compared to those who did not attend, and a family history of deafness compared to those with none. No association was found between maternal education and socio-economic disadvantage and the use of Auslan.

CONCLUSION

This Australian study found a low proportion (8.7%) of families with a DHH child who reported using Auslan. Seven child hearing loss and family factors were considered, and five were significantly associated with using Auslan at home. Children with a greater degree of hearing loss, attendance at early intervention and family history of deafness tended to use Auslan.
