BACKGROUND: Prioritized research agendas are viewed internationally as an important method for ensuring that health research meets actual areas of clinical need. There is growing evidence for speech-language therapy-prioritized research agendas, particularly in disorder-specific areas. However, there are few general research priority agendas to guide speech-language therapy research. AIMS: To collaboratively develop a prioritized research agenda for an Australian public health context with clinical speech-language therapists (SLTs), academic SLTs and consumers of speech-language therapy services. METHODS & PROCEDURES: An initial stimulus list of potential research areas for prioritization was collected from SLTs via an online survey. Two categories (service delivery and expanded scope of practice) were selected from this list for prioritization due to their relevance across multiple health services. The Nominal Group Technique (NGT) was used to develop a prioritized research agenda for each of the two categories. One NGT session was conducted with each of the three participant groups (clinical SLTs, academic SLTs, consumers) for each category (total NGT sessions = six). The prioritization data for each group within each category were summed to give a single, ranked prioritized research agenda for each category. OUTCOMES & RESULTS: Two prioritized research agendas were developed. Within each agenda, SLTs and consumers prioritized a need for more research in areas related to specific practice areas (e.g., Alternative and Augmentative Communication, Communication Partner Training), as well as broader professional issues (e.g., telehealth, working with culturally and linguistically diverse families). CONCLUSIONS & IMPLICATIONS: The current findings support the need for funding proposals and targeted projects that address these identified areas of need. WHAT THIS PAPER ADDS: What is already known on this subject Evidence-based practice is a critical component of SLT practice. There is often a disconnect between the research evidence generated and areas of clinical need, and in some areas a lack of evidence. Prioritized research agendas can help drive research in areas of clinical need. What this paper adds to existing knowledge A collaborative, prioritized SLT research agenda was developed using the NGT according to the views of clinical SLTs, academic SLTs and consumers of speech-language therapy services in a conglomerate of public health services. SLTs and consumers identified a need for further research in specific areas of SLT practice as well as broader emerging professional issues What are the potential or actual clinical implications of this work? Targeted research projects funded on a large scale are required to address these identified areas of need. Other health services around the world could replicate this prioritization process to drive research in areas of clinical need.
