The Self-Directed Learning Readiness Scale: a factor analysis study

Area of Science:

• Medical Education
• Psychometrics
• Lifelong Learning

Background:

• Physician practice requires continuous self-directed, lifelong learning.
• The Self-Directed Learning Readiness Scale (SDLRS) is designed to measure adult readiness for self-directed learning.
• Assessing the psychometric properties of the SDLRS is crucial for its valid application.

Purpose of the Study:

• To evaluate the factor structure of the SDLRS in a cohort of incoming medical students.
• To determine if the SDLRS accurately reflects readiness for self-directed learning in this specific population.
• To provide empirical evidence for the construct validity of the SDLRS in medical education.

Main Methods:

• A principal axis factor analysis with oblique rotation was applied to 58 SDLRS items.
• Confirmatory factor analyses were conducted using LISREL 8.54 to examine the measurement model.
• Data were collected from 972 first-year medical students over six years.

Main Results:

• A 4-factor confirmatory model demonstrated a good fit for the data.
• The model included four correlated substantive factors and a factor for reverse coding.
• These findings suggest a specific underlying structure for the SDLRS in this sample.

Conclusions:

• Medical educators should exercise caution when using the SDLRS to gauge medical students' self-directed learning readiness.
• The study suggests a need to re-evaluate the theoretical underpinnings and definitions of readiness for self-directed learning.
• Exploring alternative methodologies for assessing self-directed learning in medical students is advised.
