Abstract

The objective was to analyze the psychometric properties of the Adapted Tuckman
Procrastination Scale (ATPS) from its application to 764 students belonging to the private
university of metropolitan Lima. The exploratory factor analysis was used as evidence of validity
related to the internal structure of the scale, obtaining a one-dimensional structure that underlies
the 15 items that make it up, however, three items obtained factorial weights less than 0.32, the
scale being 12 items that show better adjustment rates. McDonald's Cronbach and omega
reliability coefficients were greater than 0.70 in all cases, showing internal consistency. Evidence
of validity was obtained in relation to another variable, through the correlation between ATPS
scores and academic performance, being negative and statistically significant. It is concluded that
the ATPS has adequate psychometric properties to continue with validation studies and it is
recommended to expand the sample with the objective of developing scales.
