Assessing parent interaction with deaf infants: A quantitative survey of UK professional practice.

What is already known on this subject Parental involvement is one of the greatest predictors of deaf children's language outcomes. With many deaf children born to hearing parents, parents often need guidance with how to facilitate effective communication. A recent systematic review identified the range of parent behaviours and methods used to analyse PCI in international research studies, but little evidence or guidance exists on how professionals assess this phenomenon in practice. What this study adds This is the first survey to generate large, valuable practice-based evidence for the assessment of parents' communication behaviours as they interact with their deaf infants aged 0-3. The survey recruited a range of multidisciplinary professionals working on interaction within this field: SLTs, qualified teachers of the deaf, psychologists or psychiatrists, and professionals working within deaf child and adolescent mental health services. The study reports on which behaviours these professionals assess and how, and includes information on the goal setting behaviours of practitioners. Most respondents were highly experienced; the survey, therefore, reveals expert practice within the field. What are the potential or actual clinical implications of this work? We recommend the following practice: (1) incorporate a range of parent-based behaviours in PCI assessments, including establishing joint engagement and parental sensitivity, as well as communication-focused behaviours; (2) video record PCI assessments where possible to enable professionals and parents to watch and reflect together; (3) following assessment, set parent-focused goals in collaboration with families, ensuring parents' skills, particularly their strengths, are considered. All primary caregivers should be included in the process where possible; and (4) reassess PCI regularly (at least termly) to monitor and encourage families' progress. The timing of reviews should be discussed between parent and professional.
