Factor analysis validation of the student feedback questionnaire for the subcutaneous swelling simulation model

Area of Science:

• Medical Education Technology
• Simulation-Based Learning
• Assessment and Evaluation

Background:

• Subcutaneous swelling simulation models are vital for hands-on medical training.
• Student feedback is crucial for refining these educational tools.
• This study validates a questionnaire for assessing student perceptions of these models.

Purpose of the Study:

• To validate a student feedback questionnaire for subcutaneous swelling simulation models.
• To ensure the questionnaire effectively captures student perceptions of simulation fidelity and clinical competency.
• To establish a reliable instrument for evaluating medical simulation effectiveness.

Main Methods:

• Developed a Student Feedback Questionnaire based on simulation model relevance.
• Administered the questionnaire to 265 students who used the simulation model.
• Utilized exploratory and confirmatory factor analysis for structural validation.

Main Results:

• Factor analysis confirmed a robust questionnaire structure with domains including fidelity and clinical competency.
• Students rated the simulation model highly and recommended it for future training.
• High factor loadings and a Cronbach's alpha of 0.91 indicated strong validity and reliability.

Conclusions:

• Factor analysis supports the multidimensionality of student feedback on simulation models.
• The validated questionnaire reliably identifies key aspects impacting student learning.
• A validated feedback instrument is essential for assessing subcutaneous swelling simulation models.
