Procrastination is a deleterious and increasingly pervasive phenomenon within the higher-academic domain, and the progressive refinement of its measurement tools proves vital to shed light and undertake this behavior. Thus, the present study examines renewed psychometric quality features of the Tuckman Procrastination Scale within an Argentinian sample. The sample was composed of 923 undergraduates from Buenos Aires City and its environs (80.7% female; 18.7% male; 0.5% non-binary; Mage = 26.60; SDage = 8.25). The Cordoban-Argentinian adaptation of the Tuckman Procrastination Scale was employed. Content validity analysis of the scale’s items was carried out upon consideration of expert judgments. Face validity of the instrument was analyzed via a pilot study with a subsample of undergraduates. Subsequently, a confirmatory factor analysis of the Tuckman Procrastination Scale structure was conducted, and the internal consistency of the resulting factor was examined. Finally, correlations with the Academic Motivation Scale were analyzed to provide evidence of convergent validity. Results of the Confirmatory Factor Analysis supported an adequate fit of the Tuckman Procrastination Scale’s structure in its Cordoban-version 15 items, while internal consistency was acceptable-to-excellent. Finally, convergent validity evidence mostly exhibited positive associations between Procrastination and both Amotivation and less self-determined motivational subscales of the Academic Motivation Scale, while negative associations were observed with regards to Intrinsic Motivation subscales.
