A structured interview for medical school admission, Phase 1: initial procedures and results

Area of Science:

• Medical Education
• Admissions Strategy
• Psychometrics

Background:

• Medical school interviews are often unstructured and lack reliability.
• There is a need for valid and unbiased methods for selecting medical students.

Purpose of the Study:

• To develop a structured admission interview to eliminate bias and provide valid information for medical student selection.
• To assess the preliminary reliability and validity of the developed structured interview.

Main Methods:

• 490 applicants were interviewed by two faculty members using a structured format.
• Interview scores were correlated with undergraduate GPA, MCAT scores, and Iowa Evaluation Form (IEF) scores.
• Admission status was analyzed in relation to interview performance.

Main Results:

• Good interrater agreement was observed (87%-98% agreement within one point).
• Structured interview scores showed low to moderate correlations with GPA and MCAT subscores.
• The interview accounted for 20% of the incremental variance in admission status beyond other criteria.

Conclusions:

• The structured interview provides unique information not captured by traditional metrics.
• The interview demonstrated predictive validity for admission status.
• Further follow-up data are needed to fully determine the interview's validity and utility.
