Study on the reliability and validity of standardized patient based clinical interviewing test

Abstract

Objective To evaluate reliability and validity of standardized patient based clinical interviewing test. Methods The graduating examination related data of 181 students of Traditional Chinese Medicine of Grade 2014 were collected. Cronbach'sα was used for reliability, principal component analysis and exploratory factor analysis was used for validity test, and all statistical analyses were performed in SPSS 17.0. Results Cronbach'sα for examiners' internal reliability is 0.785. Cronbach'sα for standardized patients' internal reliability is 0.645. Appropriate appearance, manner, adequate listening and expression, medical history gaining, induction and conformation of history can explain 61.762% of the variance variation. Conclusions Internal validity of test is high, and the set of items for test is appropriate, therefore this is a test worth spreading. However, the assessment of the project did not set up the doctorpatient communication barrier project and SP test scores were higher, thus resulting in a low validity, so further improvement is needed for this matter.
