Using mixed methods research to guide evidence-based practice in speech-language pathology interventions

The practice of speech-language pathology, guided by evidence-based practice, relies on high-quality research evidence to support clinical decision-making. Mixed methods research designs, which collect and integrate both quantitative and qualitative data in order to achieve a deep understanding of a phenomenon, have been presented as a way to produce research that is relevant to the complex practice settings of speech-language pathologists.

This paper aims to demonstrate the utility of mixed methods intervention research to support clinical decision-making in speech-language pathology practice. Part one provides a description of mixed methods research including its core features, design types, and indicators of quality. Part two discusses theoretical underpinnings of quantitative and qualitative approaches, and explain paradigms or theoretical stances relevant to the interpretation of mixed methods research.

An understanding of mixed methods research can contribute to evidence-based practice in speech-language pathology practice, and can help clinicians to provide services that are person-centred and sensitive to sociocultural and contextual factors.
