Psychometric Properties of Adult Inventory of Procrastination in a Turkish Sample

Abstract

The present study assessed the psychometric properties of the Adult Inventory of Procrastination for Turkish adults. The Adult Inventory of Procrastination (AIP), General Procrastination Scale (GP), and Decisional Procrastination Scale were administered to 423 Turkish adults (183 women, 240 men; M (age) = 38.7, SD = 8.24) working in the governmental institutions in Turkey. The results of the confirmatory factor analysis yielded fit index values demonstrating viability of univariate factor solution as in the original. Findings also revealed that, as predicted, the AIP score was strongly correlated with GP score (r = .66). Overall, results provided evidence for the factor validity and reliability of the Turkish version of the scale for use in Turkish adult populations.
