The study population consisted of public administration undergraduate students that has been providing by distance education by University of Brasília, in Brazil. The sample of the study consisted of 590 Brazilian students. The scale has 41 items, with total Cronbach alpha coefficient of 0.94, and reliability coefficient (KMO) of 0.94. The correlations of each item with total point were between 0.30 and 0.79. A factor analysis was run using direct oblimin rotation for construct validity, resulting in 4 factors structure explaining 47.12% of total variability. These factors are "Personnel and Dispositional Aspects," "Procedural Characteristics," "Negative Affects" and "Internalization and habituation of usage."
