INOVATIVIDADE, ENVOLVIMENTO, ATITUDE E EXPERIÊNCIA NA ADOÇÃO DA COMPRA ON-LINE/INNOVATION, INVOLVEMENT, ATTITUDE AND EXPERIENCE IN BUYING ONLINE/INNOVACIÓN, PARTICIPACIÓN, ACTITUD Y EXPERIENCIA EN LA ADOPCIÓN DE LA COMPRA ONLINE

This work seeks to analyze the inter-relationships that exist between innovation, involvement and attitude in the decomposed model of the Theory of Planned Behavior (TPB), as applied in social psychology, and experience of using the Internet in the process of buying on-line. An integrative model was prepared that made it possible to explain the relationship that exists between these factors and purchasing from the Internet. A field survey was undertaken with a non-probabilistic sample of students. A multivariate structural equation modeling method was used and applied by the Partial Least Squares (PLS) technique for checking, explaining and comparing the relationship between the constructs. The results show that intention to buy via the Internet is directly influenced by attitude and innovativeness, and attitude is influenced by involvement. No relationship was found between experience in using the Internet and buying from it.
