The INviting Co-workers to Evaluate Physicians Tool (INCEPT) provides valid and reliable multisource feedback on physician performance. A feasible number of evaluations ensure dependable scores, aiding professional development.
Area of Science:
- Medical Education
- Healthcare Professional Assessment
- Psychometrics
Background:
- Multisource feedback (MSF) instruments are crucial for assessing physician performance from various viewpoints.
- The INviting Co-workers to Evaluate Physicians Tool (INCEPT) is an MSF instrument designed for evaluating physicians' professional conduct.
- This study validates the INCEPT's psychometric properties and feasibility.
Purpose of the Study:
- To evaluate the validity, reliability, and feasibility of the INCEPT instrument.
- To determine the psychometric qualities of the INCEPT for physician performance assessment.
- To establish the number of evaluations required for reliable INCEPT scores.
Main Methods:
- Assessed performance of 218 physicians via feedback from 597 peers, 344 residents, and 822 coworkers.
- Employed exploratory and confirmatory factor analyses, multilevel regression, and generalizability analyses.
- Investigated psychometric qualities including internal consistency (Cronbach's α), item-total correlations, and interscale correlations.
Main Results:
- Identified three consistent factors across respondent groups: 'professional attitude,' 'patient-centeredness,' and 'organization and (self)-management.'
- Demonstrated high internal consistency (Cronbach's α ≥ 0.84) and acceptable to good fit in confirmatory factor analyses.
- Established that 3 peer, 2 resident, and 3 coworker evaluations yield reliable total scores; 3-4 from each group suffice for subscale reliability.
Conclusions:
- The INCEPT instrument offers a valid and reliable method for delivering physician performance feedback.
- The required number of evaluations for reliable scores is practical within clinical settings.
- Physicians should acknowledge differing perceptions among respondent groups when interpreting feedback.
