Critical Thinking: A Program Review of Doctor of Audiology Students.

Purpose: Critical thinking is a crucial component of health care, and its importance has been recognized in training medical professionals. This study reports critical thinking skills for entering doctor of audiology (AuD) students and the trajectory of the change in critical thinking skills measured 2 times over a period of 3 years.

Method: This longitudinal, descriptive, and exploratory design was implemented for programmatic review. Critical thinking skills were measured using the Health Sciences Reasoning Test (HSRT; Insight Assessment) upon entering the program and compared to measurements during the final month of academic coursework. Descriptive statistics, exploratory analyses of the HSRT scores among cohorts, the relationship of the HSRT to the graduate record examinations (GREs), and changes in the HSRT over time using a repeated measures multivariate analysis of variance were conducted.

Results: There were no significant differences in critical thinking skills between any of the cohort years. There was a significant correlation between the GRE verbal scores and OVERALL HSRT. Improvements in critical thinking skills were found between the time the students entered the graduate program and their final academic semester. Greater gains were reported for students who initially scored below the 50th percentile on the OVERALL HSRT.

Conclusions: This program review showed improvement in the critical thinking skills of AuD students during their academic training program. Information regarding critical thinking skills may be useful for programs to monitor students' clinical thinking skills and possibly include clinical and didactical activities to promote critical thinking skills.
