Abstract
Objective. Mixed methods research (MMR) integrates quantitative and qualitative methods throughout the research process to answer complex research questions. MMR designs align with the guiding frameworks of patient-centered care and social determinants of health by effectively examining the role of contextual factors and human experiences in influencing health and rehabilitation outcomes. Reporting standards and critical appraisal tools ensure the quality and transparency of the research process. MMR standards exist; yet, there is a need for reporting guidelines and an appraisal tool that meets field standards, is applicable across rehabilitation fields of study, and can accommodate the range of possibilities for combining research approaches and methods.
Methods. Mixed Methods Reporting in Rehabilitation & Health Sciences (MMR-RHS) was developed using a systematic consensus-building process in accordance with published guidance and was preregistered with the Enhancing the Quality and Transparency of Health Research Network. MMR-RHS evolved through a sequence of steps, including extensive literature review, expert consultation, stakeholder feedback, pilot testing, and tool refinement.
Results. MMR-RHS consists of 20 criteria that align with field standards for rigor and transparency, with an emphasis on integration throughout the research process, a key component of MMR.
Conclusions. A systematic process was utilized to develop the reporting standards and an appraisal tool for MMR in rehabilitation and health science. The tool is comprehensive, includes a set of criteria grounded in MMR literature, and is flexible for application to a range of MMR designs commonly seen in rehabilitation research.
Impact. The MMR-RHS may improve the quality and transparency of MMR by supporting investigators, authors, reviewers, and editors during project development, manuscript preparation, and critical review. The tool may assist readers in critical appraisal, knowledge translation, and application of published MMR findings. Ultimately, the MMR-RHS may help legitimize mixed methods in rehabilitation and health research, an important step toward understanding the complexities of health care, patient outcomes, and evolving societal health needs.
