In this article, we drew from a recently completed etiological systematic literature review (SLR) using a mixed methods approach (1) to explain the process for analyzing and synthesizing the results of 201 sources and (2) to comment on the use of Creswell et al's criteria for mixed methods approaches. We provided a detailed process description of the steps involved in this SLR, and demonstrated that a mixed methods approach, traditionally not associated with a SLR, can be used, comprehensively and explicitly, to plan, collect, analyze, synthesize, and interpret data. We offered guidelines for rehabilitation professionals who are considering performing similar studies.
