Abstract
This qualitative case study focused on the clinical reasoning of a certified occupational therapy assistant who had 16 years of practice experience. Observation and interview methods were used to collect data. Transcripts and field notes were coded using a priori codes of the forms of clinical reasoning of occupational therapists identified in published research. The study participant demonstrated the use of pragmatic, procedural, interactive, conditional, and narrative reasoning. We encourage further research to support these findings and to increase the understanding of the forms of clinical reasoning used by occupational therapy assistants.
