Evaluating clinical reasoning in first year DPT students using a script concordance test.

BACKGROUND: A script concordance test (SCT) provides a series of clinical vignettes to assess clinical reasoning in uncertainty. Appraised throughout health education literature, SCTs are cognitive assessments of clinical reasoning, though their use in Doctor of Physical Therapy (DPT) entry-level education has not been investigated. The purpose of this study was to develop and explore the reliability and validity of a SCT for first year DPT students.

METHODS: The SCT was developed and implemented over four phases. During phases one and two, DPT program faculty consulted on course content from the first-year curriculum. Thirty clinical vignettes with three follow-up questions each were constructed. The SCT was pilot tested with five clinicians in phase three to assess question clarity. During phase four, the SCT was administered to students and a reference panel via Qualtrics. First year DPT students (n = 44) and reference panel physical therapists with at least two years of experience and advanced certification (n = 15) completed the SCT. Internal consistency was analyzed using Cronbach's Alpha. Differences between student and reference panel percent-correct scores were analyzed with a t-test. Relationships between student SCT scores and academic records were explored with Spearman's Rho.

RESULTS: The SCT had an internal consistency of 0.74. A significant difference in scores was found between the students [mean 58.5 (+/-5.31)] and reference panel [65.8 (+/-4.88), p < .01]. No significant correlations between student SCT scores and academic records were found.

CONCLUSIONS: The developed SCT was reliable and demonstrated satisfactory internal consistency among test items. The SCT successfully differentiated between groups, with the reference panel demonstrating statistically significant higher percent-correct scores compared to students. SCTs may provide means to measure clinical reasoning in DPT students and lead to novel pedagogical approaches to enhance clinical reasoning.
