| Summary: | Abstract The objective of this study is to analyze the validity evidence of the Academic Procrastination Scale (APS) in a sample consisting of 1979 students from public and private universities, from different courses, 67% of the students being women, aged 18 to 68 years old (M = 22.84). The principal component analysis revealed two components, also validated by confirmatory analysis, which showed a good overall fit of a two-dimensional model: Daily Study Procrastination (a = 0.75) and Exam Study Procrastination (a = 0.75). Internal consistency was estimated through Cronbach’s alpha, obtaining 0.83 for the total scale. The study concludes that APS has satisfactory psychometric properties and suggests further validation studies and also analysis of academic procrastination in higher education students.
