Development of a standardised tool to capture parents’ use of language facilitation strategies Parent-child interaction therapy is widely used by SLPs in the treatment of developmental language difficulties. This family- centred intervention involves coaching parents to use language facilitation strategies, such as commenting on their child’s interests. There is currently no standardised tool available for SLPs to rate parents’ use of language facilitation strategies. This project will develop a standardised tool for capturing parents’ use of language facilitation strategies in a clinical context utilising a multiple methods phased research design. In Phase 1, identification of the language facilitation strategies to be included in the tool will be informed by a systematised review and an international eDelphi exercise with SLP clinicians (n = ≥ 30 recruited using snowball sampling) and SLP researchers (n = ≥ 30 recruited using purposeful sampling). In Phase 2, the tool will be validated for SLPs to rate parents’ use of language facilitation techniques with children aged between 18-36 months with language difficulties. Convenience sampling will be used to recruit parent-child dyads from the speech pathology clinic at the researcher’s workplace (n = ≥30). Video recordings of parent-child interactions will be independently rated by 2 SLPs using the developed tool. The internal consistency of the tool will be determined using Cronbach’s alpha.

Application of pulse rate on paediatric videofluoroscopic swallow studies Aims: To determine if a difference exists in penetration-aspiration detection and radiation dosage levels on 30 versus 15 pulses per second (pps) on paediatric videofluoroscopic swallow studies(VFSS). Hypothesis: The use of 30 pps in paediatric VFSS will have higher detections for the presence of penetration-aspiration and radiation dosage levels (within internationally accepted levels), compared to use of 15 pps in paediatric VFSS. Participants: Infants and children 0-16 years referred for a VFSS procedure at an Australian hospital. Study design: This is a prospective, unblinded, randomised controlled study that evaluates the rate of penetration-aspiration detection and radiation dosage levels in paediatric VFSS on 30 pps versus 15 pps in a cohort of infants and children. Participants will be randomised into one of two groups: 1) 30 pps or 2)15 pps by the principal researcher. A computer generated stratified randomisation list will be provided by the statistician. The treating paediatric speech pathologist and radiologist will be blinded to the group allocation, as they will be conferring and determining on the presence or absence of penetration and/or aspiration post VFSS. However, it is likely that the treating clinicians will be able to detect which studies have been completed at 30 versus 15pps, which is why formal blinding is difficult. For all examinations, the radiographer will record the dose area product (DAP) captured for each child at the conclusion of the VFSS.
