Dyadic synchrony in deaf mothers and hearing infants.
Harriet Bowden-Howl, Rudi Dallos, Laura Goldberg and 1 others
PMID 41712462WHAT IT FOUND
Most deaf mothers and hearing infants showed adequate or better play; 21% had less warm, less engaged play that may need support.
Lower household income was linked to poorer interaction.
Key findings
01Of 28 dyads, 5 were rated sensitive, 17 adequate, 5 intervention and 1 at-risk; 21% were at the education or intervention threshold.
02Dyads at the education or intervention threshold had lower maternal sensitivity and infant cooperation, and more maternal behaviour that did not match infant cues and more infant passivity, than dyads rated sensitive or adequate.
03Lower household income was the only demographic factor linked to this poorer interaction pattern.

What it does not show
The study included only 28 deaf mother and hearing infant pairs, so it cannot show how common these interaction patterns are or prove cause. The dyads were filmed once in a laboratory-like setting, and some deaf parents may have felt judged or pressured in a predominantly hearing environment. The CARE-Index was designed for hearing dyads, and the coding may have treated deaf mothers' touch, voice or body contact differently from hearing mothers' behaviour. Mental health was poorly measured: the study asked about depression in the family but not which family member was affected or how severe it was. The paper excluded data from 62 hearing mother dyads, so comparisons between deaf and hearing parents are not made here.
Declared interests
The Economic and Social Research Council funded the work. The paper does not report other conflicts of interest.
The easy way to misread this
Do not conclude that deaf mothers are poor interaction partners. Most dyads were rated sensitive or adequate, and whether the infant heard English or BSL did not explain the lower-rated dyads. The study is small and used a coding system designed for hearing dyads, so the 21% needing support may not be generalisable.
