Summary
A new survey effectively measures the impact of sleep medicine education. This validated instrument assesses knowledge and attitudes, proving useful for evaluating curriculum changes and educational interventions in sleep medicine.
Area of Science:
- Medical Education
- Sleep Science
Background:
- Sleep medicine education in medical curricula is historically limited.
- Initiatives like the Sleep Academic Award program aim to enhance sleep medicine training.
- Effective assessment tools are crucial for evaluating educational interventions.
Purpose of the Study:
- To develop and validate a survey instrument.
- To assess the effectiveness of curriculum development and educational interventions in sleep medicine.
Main Methods:
- A 24-item knowledge and attitude survey was developed by a panel of experts.
- The survey underwent pilot testing and modification.
- Administered to undergraduates and medical students, with sleep medicine experts as a comparison group.
Main Results:
- Item analyses (difficulty, discrimination, instructional sensitivity) met acceptable criterion-referenced test norms.
- The instrument showed discriminative validity, correlating with acknowledged expertise.
Conclusions:
- The developed instrument provides logical and empirical evidence of validity.
- It can serve as a valuable tool for assessing educational interventions in sleep medicine.
