Summary
This study validated a new radiology faculty appraisal tool. The behavior-based instrument demonstrated high reliability and validity, even after shortening, for assessing instructor effectiveness.
Area of Science:
- Medical Education
- Radiology Training
- Performance Assessment
Background:
- Effective faculty appraisal is crucial for resident education.
- Existing appraisal methods may lack objectivity and relevance.
- A behavior-based instrument was developed to address these limitations.
Purpose of the Study:
- To evaluate the reliability and validity of an experimental, behaviorally based faculty appraisal instrument in radiology residency programs.
- To compare the performance of the experimental instrument against existing institutional appraisal tools.
Main Methods:
- Radiology residents at the University of Wisconsin and Indiana University used a 53-item experimental appraisal instrument.
- Residents also completed their institution's existing appraisal form.
- The experimental instrument was subsequently shortened to 30 items.
Main Results:
- The experimental instrument showed high reliability (0.98 for both institutions).
- Correlations between the experimental and existing forms were substantial (.69 UW, .87 IU), indicating good validity.
- Shortening the instrument minimally impacted reliability and validity.
Conclusions:
- The behavior-based appraisal instrument is a reliable and valid tool for assessing radiology faculty.
- The instrument effectively captures resident perceptions of instructor effectiveness.
- A shortened version maintains the tool's psychometric properties.
