Objectives: This research used text mining to determine the impact of curricular experiences in each year of study on the formation of professional identity among students aspiring to become physical therapists (PTs) and occupational therapists (OTs).
Methods: This study included 210 students (126 PT and 84 OT) enrolled at a single rehabilitation university in Japan in 2020 and 2021. These participants completed an open-ended questionnaire on personal growth 6, 12, 18 and 24 months after enrollment. Text mining was used to extract frequently occurring nouns from descriptive text data at these four time points. A hierarchical cluster analysis was then performed to generate clusters. The number of students mentioning at least one noun in each cluster was counted, and the proportion of students in each cluster was compared across the four time periods using Cochran’s Q test.
Results: The 16 nouns that appeared more than 30 times in 1073 sentences were classified into four clusters: “action plan for passing the credit certification examination”, “communication skill”, “medical knowledge” and “school life with clinical practice in mind”. The proportion of students belonging to the four clusters varied across periods. “Action plan for passing the credit certification examination” and “communication skill” differed significantly across periods (p<0.0001 and p=0.0008, respectively).
Conclusions: The results reveal how students have grown in their curriculum. Their growth was transformative.
