Importance: No single cognitive screen adequately captures all cognitive domains that are important for inpatient occupational therapy treatment planning., Objective: To quantify the content validity of a novel 22-item cognitive screen, the Gaylord Occupational Therapy Cognitive (GOT-Cog) screen, developed to better inform inpatient occupational therapy treatment planning., Design: Delphi-style expert panel review., Setting: Long-term acute care hospital., Participants: The first panel was attended by four occupational therapists, two speech-language pathologists, one physician assistant, and two neuropsychologists; the second, by four occupational therapists, one speech-language pathologist, and one physician assistant., Intervention: Each Delphi panel discussed the relevance, essentiality, and clarity of each item. After each discussion, panelists completed a content validity survey to summarize their evaluation of each item., Outcomes and Measures: On the basis of panelists' survey responses, item- and scale-level relevance, essentiality, and clarity were quantified by calculating the respective content validity index (CVI), content validity ratio (CVR), and content clarity index (CCI). Universal agreement (UA) and κ statistics were also calculated, as appropriate., Results: Upon presenting the initial 23-item instrument covering 10 cognitive domains to the first Delphi panel, several questions were added, removed, or rewritten, resulting in a 22-item instrument representing nine domains. After the second panel, several questions were again rewritten, and the domains reorganized. All scale-level metrics improved, including CVI (from 0.87 to 1.0), UA (0.52 to 1.0), CVR (0.43 to 0.94), and CCI (2.26 to 2.92)., Conclusions and Relevance: GOT-Cog displays overall excellent content validity and can proceed to construct validity testing. Plain-Language Summary: By reporting on the content validity of the Gaylord Occupational Therapy Cognitive screen, this brief report begins the necessary process of evaluating the measure's overall validity and reliability., (Copyright © 2024 by the American Occupational Therapy Association, Inc.)
