Background: Assessment tools that assess pragmatic skills in adults with a mild-severe traumatic brain injury (TBI) are hard to access, not person-centred and have a high risk of clinician bias. The Pragmatics Profile is an informant report tool that was originally designed to assess pragmatic skills in people with a developmental disability. Aims: The aim of this study was to seek consensus from a panel of experts and create a version of the Pragmatics Profile for the TBI population. Methods and Procedures: A three-round modified Delphi methodology panel of 13 experts were invited to comment anonymously on the suitability of each question from the Pragmatics Profile modified for those with TBI until [greater than or equal to] 80% agreement was reached. Outcomes and Results: The Pragmatics Profile (TBI) included 66 questions that achieved consensus after three rounds of the Delphi panel. Qualitative analysis illuminated themes relating to adults with TBI and the need to include contextual factors. Conclusions and Implications: The outcome of this project was a revised version of the Pragmatics Profile which is suitable for adults with a mild-severe TBI, informed by experts and freely available online. Future research exploring the tool's utility and acceptability is the next step in its evaluation.
