Propiedades psicométricas del TMBS en universitarios

Abstract

This study analyzes the psychometric properties of the Time Management Behavior Questionnaire (TMBS), adapted for use with Colombian university students, and explores construct validity using the Rasch model, discriminant validity with regard to an academic procrastination test, and concurrent validity with average performance. The reliability and length of the scale and differential item functioning were also analyzed. The sample was made up of 494 university students from nine degree programs and two universities. The results show good fit to the Rasch model, suitable reliability values and items without differential functioning, and suggest that the Likert scale categories may be reduced from five to four. Negative significant associations were found with procrastication, and positive significant associations with grades. The conclusions offer recommendations for using the test in a Latin American context.
