Overview of a special issue on complexity, alignment, and enrichment in communication partner training for aphasia

Background: Communication partner training (CPT) is a widely recognized approach in aphasia; yet, the critical elements that contribute to successful CPT remain unclear. Further scrutiny of theoretical constructs, rationales, approaches and outcomes is needed in order to further the development of CPT and ensure effective and efficient practices.
Aims: The objective of this introduction is to describe the rationale and create a context for the articles in this special issue on CPT in aphasia.
Main Contribution: This introduction defines communication partner training, briefly describes significant research and approaches to CPT in aphasia, and explains how the concepts of complexity, alignment and enrichment might expand our understanding of CPT and contribute to innovative research and practice in the area.
Conclusions: This introduction and special issue expands our understanding of CPT and challenges clinicians and researchers to consider additional perspectives on CPT.
