Collaboration between parents and SLTs produces optimal outcomes for children attending speech and language therapy: Gathering the evidence.

A preliminary programme theory of collaborative practice with parents was drafted using a realist approach. Potential contextual factors (C), mechanisms (M) and outcomes (O) were presented which could be configured into causal mechanisms to help explain what works for whom in what circumstances. CMO configurations were drafted, based on the relevant literature, which serve as exemplars to illustrate how this methodology could be used. In order to debate, test and expand our hypothesized programme theory for collaborative practice with parents, further testing against a broader literature is required alongside research to explore the functionality of the configurations across contexts. This paper highlights the importance of further research on collaborative practice with parents and the potential value of realist evaluation methodology. What this paper adds Current policy in education, health and social care advocates for family-centred care and collaborative practice with parents. Thereby, collaborative practice is the preferred practice for SLTs and parents. In this paper, we explore collaborative practice and use a realist evaluation approach to achieve the aim of setting a research agenda in this area. Researchers use realist evaluation, a methodology originally developed by Pawson and Tilley in the 1990s, to explore the causal link between interventions and outcomes, summarized as what works, how, for whom, in what circumstances and to what extent. Realist evaluation provides a framework to explore configurations between contexts (C), mechanisms (M) and outcomes (O). We used this methodology to take a first step at making explicit what collaborative practice is and how it might be achieved in different contexts. We did this by drafting a preliminary programme theory about collaborative practice, where we made explicit what context factors and mechanisms might influence outcomes in collaborative practice between parents and SLTs. Based on this programme theory, we argue for the need to develop a research agenda on collaborative practice with parents of children with speech, language and communication needs. The steps between a programme theory and a research agenda could entail exploring each CMO, or step in the programme theory, and evaluating it against the existing literature-both within and beyond speech and language therapy-to see how far it stands up. In this way, gaps could be identified that could be converted into research questions that would stimulate debate about a research agenda on collaborative practice. Understanding how collaborative practice can be achieved in different contexts could support SLTs to use mechanisms to optimise collaborative practice intentionally and tailor interventions to the specific needs of families, thereby enhancing collaborative practice between parents and SLTs.
