Importance: Assessments that evaluate health care providers’ communication in acute rehabilitation settings remain scarce; this article contributes to the knowledge base.

Objective: To assess the reliability and validity of the Clinical Assessment of Modes–Therapist version (CAM–T) from the provider’s perspective.

Design: Cross-sectional, psychometric study.

Setting: Acute care and acute inpatient rehabilitation.

Participants: Ninety-six clients and 32 providers (occupational therapy, physical therapy, and nursing).

Measures: The CAM–T was psychometrically evaluated using classical test theory and Rasch analytic approaches.

Results: The findings offer strong evidence for the CAM–T’s reliability and validity for evaluating overall communication and adequate evidence for evaluating individual communication modes.

Conclusion and Relevance: The CAM–T may be used by providers as a self-assessment of communication in occupational therapy and in associated rehabilitation professions.

What This Article Adds: This article offers evidence in support of the CAM–T’s reliability and validity for evaluating health care providers’ communication with clients in acute rehabilitation settings. The CAM–T may be used to evaluate providers’ overall communication and individual mode use as described in the Intentional Relationship Model.
