Abstract

Background. Speech and language pathology (SLP) for aphasia is a complex intervention delivered to a heterogeneous population within diverse settings. Simplistic descriptions of participants and interventions in research hinders replication, interpretation of results, guideline and research developments through secondary data analyses.

Aim. To describe the availability of participant and intervention descriptors in existing aphasia research datasets.

Method. Systematically identified aphasia research datasets contained ≥ 10 participants, time since stroke and a measure of language ability. We extracted participant and SLP intervention descriptions and considered the availability of data compared to historical and current reporting standards. We developed an extension to the TIDieR checklist to support
meaningful classification of the SLP interventions to support secondary data synthesis and analysis.

Result. Of 11,314 identified records we screened 1131 full texts and received 75 dataset contributions. We extracted data from 99 additional public domain datasets. Participant age (97.1%) and sex (90.8%) were commonly available. Prior stroke (25.8%), living context (12.1%) and socio-economic status (2.3%) were rarely available. Therapy impairment target,
frequency and duration were most commonly available but predominately described at group level. Home practice (46.3%) and tailoring (functional relevance 46.3%) were inconsistently available.

Discussion. Gaps in the availability of participant and intervention details were significant, hampering clinical implementation of evidence into practice and development of our field of research.

Conclusion. Improvements in the quality and consistency of participant and intervention data reported in aphasia research are required to maximise clinical implementation, replication in research and the generation of insights from secondary data analysis.
