title: The validity and reliability of a problem-based learning implementation questionnaire.
abstract: OBJECTIVE
  The aim of this paper is to provide evidence for the validity and reliability of a questionnaire for assessing the implementation of problem-based learning (PBL). This questionnaire was developed to assess the quality of PBL implementation from the perspective of medical school graduates.
  
  
  METHODS
  A confirmatory factor analysis was conducted to assess the validity of the questionnaire. The analysis was based on a survey of 225 graduates of a problem-based medical school in Indonesia.
  
  
  RESULTS
  The results showed that the confirmatory factor analysis model had a good fit to the data. Further, the values of the standardized loading estimates, the squared inter-construct correlations, the average variances extracted, and the composite reliabilities all provided evidence of construct validity.
  
  
  CONCLUSIONS
  The PBL implementation questionnaire was found to be valid and reliable, making it suitable for evaluation purposes.
