Background:
The Cognitive Behavior Survey (CBS) assesses learner behavior in healthcare-related fields.
Purpose:
The study aims were to evaluate the factorial validity of the CBS, which purports to measure three dimensions of learner behavior--conceptualization, reflection, and memorization--and propose and test an alternative model including its time invariance.
Methods:
The CBS was administered to 3 cohorts of medical students upon matriculation and at the end of their 1st and 2nd year.
Results:
Confirmatory factor analysis (CFA) did not support the original CBS model. Exploratory factor analysis (EFA) with an independent sample provided a new model. Retesting the EFA model using CFA with the original sample yielded a model with improved fit and time invariance.
Conclusions:
This study provides evidence for the original CBS 3-factor structure but requires alternative scoring for a time-invariant model.
